Operation effect of installation brush of mechanical grille cleaning machine

The mechanical grille is a kind of sewage treatment equipment which can continuously and automatically intercept and remove all kinds of sundries in the fluid It can be widely used in urban sewage treatment Tap water manufacturing industry, power plant intake, in addition, it can also be used as the pre screening equipment in the wastewater treatment process of textile industry, food industry, paper industry, leather products and other manufacturing industries It is one of the solid-liquid screening equipment in China at present Rotary soft brush is installed on the original frame of rotary grille machine at the slag discharge port In addition to the rotation of mechanical grille, the soft brush also cleans up the dirt picked up along with the rotation, greatly improving the working efficiency, reducing the pressure of mechanical grille, and improving the service life of the machine Rotary grid cleaning machine (also known as "solid-liquid separator") is widely used in urban sewage treatment plant, water company, pump station, power plant intake, automatic interception and removal of floating objects in the water, to ensure the normal operation of the next process, and also can be used in the solid-liquid separation equipment of textile industry, textile factory, breeding farm, tannery, paper industry, brewing, sugar manufacturing and food industry Working principle: mechanical grille is a group of rotary grille chains assembled by a tooth rake Under the drive of the motor reducer, the tooth harrow chain rotates against the water flow in a large direction, scoops up the scum suspended on the water surface, and when the tooth harrow chain is transported to the upper end of the machine, because of the guide of the groove wheel and the curved rail, the relative self-cleaning movement occurs between each group of tooth harrow, and most of the solid substances fall down by gravity The other part uses the reverse movement of the sweeper to clean up the sundries stuck on the tooth rake According to the large direction of water flow, the tooth rake chain is similar to the grid, and the tooth rake clearance assembled on the tooth rake chain shaft can be selected according to the application conditions When the tooth rake separates the solid suspended matter in the fluid, it can ensure the smooth flow of water The whole working process is continuous or intermittent Product features The main advantages of the machine are high degree of automation system, efficient separation, small driving force consumption, low noise and good anti-corrosion performance The upgraded rotary grid cleaner rotates the soft brush on the customized installation of the inspection port to achieve better cleaning effect It can ensure the continuous stability of the work without human care, and it has set the mechanical overload safety guarantee Protective device, when the machine breaks down, the shear pin is cut off, which can prevent the machine from overload and damage the machine parts The machine can adjust the operation interval of the machine at will according to the needs of customers to achieve periodic operation; it can automatically control the start and stop of the machine according to the liquid level difference between the front and rear of the grid; and it has manual control function to facilitate maintenance Customers can choose according to different work needs Because the machine architecture design is reasonable, when the machine is working, it has too strong self-cleaning ability, and will not produce blocking phenomenon, so the daily repair workload is very small Performance characteristics 1 Automatic control of scraper movement (according to customer requirements, select program controller and liquid level difference control) 2 A set of guide rope mechanism is designed carefully, which completely solves the trouble of disordered rope 3 The limit switches of the upper and lower height width ratio are set When the scraper is lowered to the bottom of the well, the galvanized steel wire rope loses its gravity, and the loose rope switch of the upper moving pulley mechanism acts; when the scraper is at the rising limit position, the switch acts and the power supply is cut off instantly 4 A set of induction switch is set to control the opening and closing of the scraper to ensure that the opening and closing action of the scraper is in place and reliable 5 Over torque protection device is set When the working load of scraper exceeds the design value, the device will act, cut off the power supply and give an alarm 6 When there is too much garbage piled up at the bottom of the well, the scraper will be lowered and blocked, the upper end of the rope release switch will act, stop lowering and closing the rake, and the accumulated garbage will be removed in batches Technical parameters and model selection: the machine is customized according to the flow of water required by the customer, the width and depth of the civil engineering channel, the gap between the teeth and harrow, etc The specification and model of the machine are divided into shg300-3600 according to the machine width If the machine width is more than 1800mm, it will be made into parallel machine, and the middle part will share the wall panel The gap of tooth rake grid can be divided into 1mm, 3mm, 5mm, 10mm, 15mm, 20mm, 30mm, 40mm, 50mm and other required specifications and models The selection is based on the flow of water, the ratio of lifting height to width, the total amount of solid-liquid separation equipment, the appearance and particle size of the separated substances, and different materials The machine groove depth is customized by the customer, and can be customized according to the customer's needs and the actual application situation Generally not less than 0.8m, not more than 15m The control system of the system is selected or provided by the customer The general quotation does not include the control cabinet It can be applied when the three-phase power supply is connected to the site The local start stop control button is selected on the field control cabinet, and the start stop button of the machine and the start stop and accident signal indicators are set on the field control cabinet In order to save energy consumption, all signal indicators are energy-saving type, and the motor protector is set in the control cabinet The connection between PLC system and control cabinet of the whole plant can be considered for the control cabinet The data signal reflecting the machine operation from the control cabinet is sent to the control room In addition, the control data signal from PLC to the control cabinet controls the opening and shutting down of the grid The control cabinet can be made of carbon steel anti-corrosion or 304 stainless steel shell, which is rainproof outside the room.
