Filter plate cleaning device for filter press

Abstract

This utility model relates to the field of filter press technology, specifically a filter plate cleaning device for a filter press. It includes a filter press frame, with filter plates mounted on the upper end of the frame. A cleaning mechanism is installed on the top of the frame, and a waste liquid circulation mechanism is located above the frame. By incorporating the cleaning mechanism, a hydraulic press drives a sliding block to move left and right on the base frame, pushing it above the filter plates for cleaning. After being pressurized by a water pump, the liquid flows through a telescopic pipe and a guide channel, then is sprayed out by a nozzle for cleaning. The cleaning height can be adjusted by a hydraulic device. The waste liquid circulation mechanism allows the connecting rod to move along with the sliding block, enabling the water collection tank to collect waste liquid as the cleaning components above move. The waste liquid is filtered through a filter screen and flows into a circulating water tank. The filtered liquid is then pumped by a water pump through a delivery pipe and the water tank, achieving wastewater recycling and reducing sewage discharge costs.

Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically to a filter plate cleaning device for a filter press. Background Technology

[0002] With the continuous acceleration of modern industrial production and increasingly stringent requirements for environmental protection and resource utilization, filter presses, as key equipment for achieving efficient solid-liquid separation, are widely used in many fields such as chemical and pharmaceutical industries, playing an indispensable role. During operation, the filter plates, as the core components, frequently come into contact with the filtered materials. With the increase in the number of uses, a large number of impurities will adhere to the surface of the filter plates and the pores of the filter cloth, gradually forming stubborn deposits, affecting the filtration performance and working efficiency of the filter plates, and thus restricting the smooth progress of the entire production process. Traditional manual cleaning methods not only consume a lot of manpower, but also make it difficult to guarantee the cleaning effect, which can no longer meet the pace of large-scale and automated production. Therefore, a filter plate cleaning device for filter presses has emerged.

[0003] However, existing filter plate cleaning devices for filter presses have the following problems: First, the nozzles cannot flexibly cover all areas of the filter plate, resulting in some areas having residual impurities due to insufficient water rinsing. It is difficult to systematically clean the filter plate from top to bottom, and stubborn deposits on the top and bottom of the filter plate cannot be effectively removed. At the same time, single-sided or partial cleaning methods cannot take into account both sides of the filter plate, resulting in reduced cleaning efficiency and affecting the overall operational stability and production continuity of the filter press. Second, the wastewater generated from rinsing the filter plates will be directly discharged or discarded, and cannot be recycled, resulting in a large waste of water resources and increasing the water consumption cost in the enterprise's production. The lack of circulating rinsing capacity requires the enterprise to continuously replenish a large amount of water, causing the cleaning cost to rise continuously with the expansion of production scale. Furthermore, it is impossible to use the relatively clean wastewater after filtration for preliminary rinsing, which reduces cleaning efficiency and results in inefficient use of resources. Utility Model Content

[0004] The purpose of this invention is to provide a filter plate cleaning device for a filter press to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a filter plate cleaning device for a filter press, comprising a filter press frame, a filter plate being provided at the upper end of the filter press frame, a cleaning mechanism being installed at the top of the filter press frame, and a waste liquid circulation mechanism being provided above the filter press frame.

[0006] Preferably, the cleaning mechanism includes a base frame fixedly connected to the top of the filter press frame, a hydraulic press fixedly connected to one side of the base frame, the hydraulic press outputs power to move the slide in the horizontal direction, the slide is fixedly connected to rollers through two openings to facilitate the movement of the slide, and the limiting groove opened along the top surface of the base frame of the rollers facilitates the movement of the slide under the force of the hydraulic press, reducing the frictional resistance when the slide moves.

[0007] Preferably, water tanks are fixedly connected to both sides of the slide block. A water pressure pump is installed on the top surface of the water tank to pressurize the water for subsequent cleaning. A telescopic pipe is installed on the bottom surface of the water tank, and a guide channel is fixedly connected to the bottom surface of the telescopic pipe. A nozzle is installed on one side of the guide channel. After the water pressure pump pressurizes the liquid in the water tank, the liquid flows through the telescopic pipe into the guide channel and is then sprayed out by the nozzle to clean both sides of the filter plate. The water tank is connected to the guide channel through a hydraulic device. The hydraulic device outputs power to make the guide channel move in the vertical direction to achieve all-round cleaning of the filter plate.

[0008] Preferably, the waste liquid circulation mechanism includes a connecting rod fixedly connected to one side of the slide, and a water receiving tank fixedly connected to one side of the connecting rod to collect the cleaning waste liquid above. Four pulleys are fixedly connected to the bottom surface of the water receiving tank. The pulleys move along the guide rails opened on the filter press frame. When the slide is subjected to the force of the hydraulic press, it moves in the horizontal direction, which drives the connecting rod to move the water receiving tank. At this time, the pulleys move in the guide rails to reduce the movement resistance of the water receiving tank.

[0009] Preferably, a filter screen is fixedly connected to the inner edge of the opening on one side of the water receiving tank to filter the water after cleaning. A circulating water tank is fixedly connected to one side of the water receiving tank, and the liquid in the water receiving tank flows through the filter screen into the circulating water tank. A water pump is installed on the top surface of the circulating water tank, and the water pump draws the filtered liquid in the circulating water tank into a delivery pipe installed on it. One end of the delivery pipe is connected to the water tank to realize the recycling of the liquid.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model incorporates a cleaning mechanism consisting of a hydraulic press and a water pump. The hydraulic press drives the slide to move left and right on the base frame, pushing the cleaning mechanism above the filter plates for individual cleaning. The friction during movement is reduced by rollers fixed on one side of the slide and limiting grooves on the base frame. Water tanks fixed on both sides of the slide are pressurized by the water pump, and the liquid flows through the telescopic pipe and guide groove, and is then sprayed out by the nozzles to clean both sides of the filter plates. The height of the guide grooves can be adjusted by the hydraulic device to achieve all-round cleaning of the filter plates from top to bottom, ensuring that the nozzles can accurately cover all areas of the filter plates, avoiding cleaning blind spots, and forming a continuous flushing path. This effectively removes stubborn impurities from the surface and pores of the filter plates. The dual-side synchronous cleaning design achieves all-round cleaning of both sides of the filter plates, shortens the cleaning cycle, reduces manual intervention, lowers labor intensity, and improves the overall operating efficiency and production continuity of the filter press.

[0012] 2. This utility model incorporates a waste liquid circulation mechanism by adding a water receiving tank and a water pump. When the slide moves, the connecting rod connected to one side moves accordingly, allowing the water receiving tank to collect waste liquid by moving with the cleaning parts above. The pulleys below the water receiving tank reduce the resistance during its movement. The waste liquid collected by the water receiving tank flows into the circulating water tank after being filtered through the filter screen installed on it. The filtered liquid flows through the delivery pipe and the water tank under the suction of the water pump, realizing the recycling of wastewater. This achieves dual optimization of resource utilization and cost control, reducing the amount of water replenishment and lowering the company's water costs. The secondary rinsing not only effectively utilizes the filtered water resources, but also removes most of the loose dirt on the surface of the filter plate through circulating water in the initial rinsing stage, reducing the pressure and water consumption of subsequent cleaning, improving cleaning efficiency, and reducing sewage discharge costs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6The present invention provides an embodiment of a filter plate cleaning device for a filter press, comprising a filter press frame 1, a filter plate 2 disposed on the upper end of the filter press frame 1, a cleaning mechanism 3 installed on the top of the filter press frame 1, and a waste liquid circulation mechanism 4 disposed above the filter press frame 1.

[0025] Furthermore, the cleaning mechanism 3 includes a base frame 301 fixedly connected to the top of the filter press frame 1. A hydraulic press 302 is fixedly connected to one side of the base frame 301. The hydraulic press 302 outputs power to move the slide 303 in the horizontal direction. The slide 303 is fixedly connected to rollers 304 through two openings to facilitate the movement of the slide 303. The rollers 304 have a limiting groove 305 opened along the top surface of the base frame 301 to facilitate the movement of the slide 303 under the force of the hydraulic press 302, reducing the frictional resistance when the slide 303 moves. The hydraulic press 302 drives the slide 303 to move left and right on the base frame 301. The frictional force during movement is reduced by the rollers 304 fixed on one side of the slide 303 and the limiting groove 305 opened on the base frame 301. The hydraulic press 302 pushes the cleaning mechanism 3 above the filter plates 2 for cleaning one by one.

[0026] Furthermore, water tanks 306 are fixedly connected to both sides of the slide 303. A water pressure pump 307 is installed on the top surface of the water tank 306 to pressurize the water for subsequent cleaning. A telescopic pipe 308 is installed on the bottom surface of the water tank 306, and a guide groove 309 is fixedly connected to the bottom surface of the telescopic pipe 308. A nozzle 310 is installed on one side of the guide groove 309. After the water pressure pump 307 pressurizes the liquid in the water tank 306, the liquid flows through the telescopic pipe 308 into the guide groove 309, and is then sprayed out by the nozzle 310 to clean both sides of the filter plate 2. The water tank 306 is connected to the guide channel 309 via a hydraulic device 311. The hydraulic device 311 outputs power to make the guide channel 309 move in the vertical direction to achieve all-round cleaning of the filter plate 2. After being pressurized by the water pressure pump 307, the water tank 306 fixed on both sides of the slide 303 flows through the telescopic pipe 308 and the guide channel 309, and is then sprayed out by the nozzle 310 to clean both sides of the filter plate 2. The height of the guide channel 309 can be adjusted by the hydraulic device 311 to achieve all-round cleaning of the filter plate 2 from top to bottom.

[0027] Furthermore, the waste liquid circulation mechanism 4 includes a connecting rod 401 fixedly connected to one side of the slide 303. A water collection tank 402 is fixedly connected to one side of the connecting rod 401 to collect the cleaning waste liquid above. Four pulleys 403 are fixedly connected to the bottom surface of the water collection tank 402. The pulleys 403 move along the guide rail 404 opened on the filter press frame 1. When the slide 303 is subjected to the force of the hydraulic press 302, it moves horizontally, driving the connecting rod 401 to move the water collection tank 402. At this time, the pulleys 403 move within the guide rail 404 to reduce the movement resistance of the water collection tank 402. When the slide 303 moves, the connecting rod 401 connected to one side moves accordingly, so that the water collection tank 402 moves with the displacement of the cleaning parts above to collect waste liquid. The pulleys 403 below the water collection tank 402 can reduce its resistance during movement.

[0028] Furthermore, a filter screen 405 is fixedly connected to the inner edge of the opening on one side of the water receiving tank 402 to filter the cleaned water. A circulating water tank 406 is fixedly connected to one side of the water receiving tank 402, allowing the liquid in the water receiving tank 402 to circulate. The liquid in the water receiving tank 402 flows into the circulating water tank 406 after being filtered by the filter screen 405. A water pump 407 is installed on the top surface of the circulating water tank 406. The water pump 407 draws the filtered liquid in the circulating water tank 406 into a conveying pipe 408 installed on it. One end of the conveying pipe 408 is connected to the water tank 306 to realize the recycling of the liquid. The waste liquid collected by the water receiving tank 402 flows into the circulating water tank 406 after being filtered by the filter screen 405 installed on it. The filtered liquid flows through the conveying pipe 408 and the water tank 306 successively under the suction of the water pump 407, realizing the recycling of wastewater.

[0029] Working principle: The hydraulic press 302 drives the slide 303 to move left and right on the base frame 301. Friction during movement is reduced by rollers 304 fixed on one side of the slide 303 and limiting grooves 305 on the base frame 301. The hydraulic press 302 pushes the cleaning mechanism 3 above the filter plates 2 for cleaning. Water tanks 306 fixed on both sides of the slide 303 are pressurized by the water pump 307. The liquid flows through the telescopic pipe 308 and the guide channel 309, and is then sprayed out by the nozzle 310 to clean both sides of the filter plates 2. The height of the guide channel 309 can be adjusted by the hydraulic press. Adjustment of position 311 enables comprehensive cleaning of filter plate 2 from top to bottom. When slide 303 moves, connecting rod 401 connected to one side moves accordingly, allowing water tank 402 to collect waste liquid as the cleaning parts above move. The pulley 403 below water tank 402 reduces resistance during movement. Waste liquid collected by water tank 402 is filtered through filter screen 405 and flows into circulating water tank 406. The filtered liquid is then pumped by water pump 407 and flows through conveying pipe 408 and water tank 306, realizing the recycling of wastewater.
