Description

Technical Field

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

[0002] A filter press is a device used for solid-liquid separation, primarily to separate solid particles suspended in a liquid. During the use of a filter press, solid-liquid separation can lead to the accumulation of a large number of solid particles on the filter cloth or filter plates. This not only reduces filtration efficiency and processing capacity but may also cause the filter plates to become clogged or corroded. Therefore, a filter press cleaning device is required to clean it.

[0003] For example, CN214714623U discloses a cleaning device for a filter press, including a cleaning plate. A water pump is fixedly connected to the upper surface of the cleaning plate, and a water-binding belt column is also fixedly connected to the upper surface of the cleaning plate.

The multi-functional fixing leg includes a vertical sliding plate, a fixed support leg, and a horizontal L-shaped sliding plate. A vertical groove is formed on the upper surface of the fixed support leg, and a vertical sliding plate is movably connected inside the vertical groove. This cleaning device for a filter press, through the setting of the multi-functional fixing leg, can meet the size of the fixing arm on the filter press, allowing the device to be fixed for cleaning on filter presses of different specifications, increasing the practicality of the device. The height of the device can be adjusted by the multi-functional fixing leg, and the cleaning area, intensity, and cleanliness can all be adjusted, meeting the versatility of the device's use.

[0004] The above-mentioned patent has the following defects in use:

[0005] The cleaning of filter presses mainly relies on water spraying, which is relatively simple and takes a lot of time to ensure thorough cleaning, resulting in low cleaning efficiency and water waste. Therefore, this utility model proposes a filter press cleaning device. Utility Model Content

[0025] 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.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a filter press cleaning device, including a filter press body 1, a water storage tank 2 at the bottom of the filter press body 1, an activated carbon filter plate 4 embedded and connected at the top of the water storage tank 2, and the top of the activated carbon filter plate 4 in contact with the bottom of the filter press body 1, an L-shaped plate 3 fixedly connected to one end of the water storage tank 2, and a spraying and scraping mechanism 7 between the front end of the water storage tank 2 and the top of the L-shaped plate 3, and a pair of connecting pieces 10 fixedly connected to both the front and rear ends of the filter press body 1, and both pairs of connecting pieces 10 are threadedly connected to the top of the water storage tank 2 by bolts.

[0027] When cleaning is required during use, the filter press body 1 is first connected to the water storage tank 2 via the connecting plate 10 and bolts. The activated carbon filter plate 4 can filter and adsorb the water that falls during cleaning, removing fixed particles and odors, restoring the water to its cleanliness for recycling, reducing water waste and improving resource utilization. After cleaning, the filter press body 1 can be separated from the water storage tank 2 again via the connecting plate 10 and bolts.

[0028] like Figure 1-2 As shown, a water inlet 5 is cut at the top of the water storage tank 2, and a sealing plug 6 is fitted on the top of the water inlet 5, with the outer wall of the sealing plug 6 in close contact with the inner wall of the water inlet 5.

[0029] During use, this solution allows the sealing plug 6 to be opened when water is added to the water storage tank 2, so that water can enter the water storage tank 2 through the water inlet 5. After adding water, the sealing plug 6 is closed to prevent dust from entering the water storage tank 2.

[0030] like Figure 1-3As shown, the spraying and scraping mechanism 7 includes multiple water pumps 701. The bottom ends of the multiple water pumps 701 are fixedly connected to the top end of the L-shaped plate 3. Water guide pipes 702 are fixedly connected between the front ends of the multiple water pumps 701 and the front end of the water storage tank 2. Multiple telescopic hoses 703 are embedded and connected to the top end of the L-shaped plate 3. The top ends of the multiple telescopic hoses 703 are fixedly connected to the bottom ends of the multiple water pumps 701. Spray rows 704 are fixedly connected to the bottom ends of the multiple telescopic hoses 703. Scrapers 705 are fixedly connected to the bottom ends of the spray rows 704. The outer walls of the multiple scrapers 705 are in contact with the inner wall of the filter press body 1. A lifting mechanism 8 is provided between the top end of the water storage tank 2 and the top ends of the multiple spray rows 704. Both ends of the multiple scrapers 705 are inclined, and the surfaces of the multiple scrapers 705 are polished.

[0031] During operation, multiple water pumps 701 draw water from the water storage tank 2 through the water guide pipe 702 and flow it into the telescopic hose 703. The water is then sprayed outward through the spray nozzle 704 and directed towards the interior of the filter press body 1. At the same time, multiple scrapers 705 scrape the interior of the filter press body 1, achieving simultaneous water spraying and scraping cleaning. This allows for rapid and comprehensive cleaning of the filter press body 1, reducing cleaning time, minimizing water waste, and improving cleaning efficiency.

[0032] like Figure 1-3 As shown, the lifting mechanism 8 includes an electric telescopic rod 801 fixedly connected to the top of the water storage tank 2. A movable plate 802 is fixedly connected to the top of the electric telescopic rod 801. The top of the movable plate 802 has multiple round holes, and the movable plate 802 is respectively fitted onto the outer wall of multiple telescopic hoses 703 through the multiple round holes. Multiple pairs of round rods 803 are fixedly connected to the bottom of the movable plate 802, and the bottom of the multiple pairs of round rods 803 are respectively fixedly connected to the top of multiple spray nozzles 704. A movable vibrating material mechanism 9 is provided between one end of the movable plate 802 and the inner wall of the L-shaped plate 3.

[0033] During use, the electric telescopic rod 801 pulls the movable plate 802 downward, which in turn drives multiple spray nozzles 704 and scrapers 705 downward through multiple pairs of round rods 803. This causes the multiple spray nozzles 704 and scrapers 705 to penetrate deep into the interior of the filter press body 1, so as to thoroughly clean the filter press body 1.

[0034] like Figure 1-2 and Figure 4As shown, the movable vibrating material mechanism 9 includes a pair of auxiliary telescopic rods 901. One end of each pair of auxiliary telescopic rods 901 is fixedly connected to one end of the movable plate 802. The ends of each pair of auxiliary telescopic rods 901 away from the movable plate 802 are fixedly connected to movable hemispheres 902. Springs 903 are sleeved on the outer walls of each pair of auxiliary telescopic rods 901, and the two ends of the springs 903 are fixedly connected to the auxiliary telescopic rods 901 and the movable hemispheres 902, respectively. Multiple pairs of fixed hemispheres 904 are fixedly connected to the inner wall of the L-shaped plate 3. The outer walls of each pair of movable hemispheres 902 are in contact with the inner wall of the L-shaped plate 3 and are located on top of the multiple pairs of fixed hemispheres 904.

[0035] During operation, when the movable plate 802 moves downward, a pair of auxiliary telescopic rods 901 move synchronously, driving a pair of movable hemispheres 902 to move along the inner wall of the L-shaped plate 3. During this movement, they repeatedly come into contact with multiple pairs of fixed hemispheres 904. Under the pressure of the protruding outer walls of the multiple pairs of fixed hemispheres 904, the pair of movable hemispheres 902, assisted by the elastic displacement of the auxiliary telescopic rods 901 and springs 903, repeatedly separate and collide with the inner wall of the L-shaped plate 3, generating vibration. This vibration is transmitted to the movable plate 802 and multiple pairs of round rods 803 through the auxiliary telescopic rods 901, causing the solid particles remaining on the connected spray nozzles 704 and scrapers 705 to fall off under the action of vibration. This prevents residue from forming and avoids interference with the cleaning of the filter press body 1, ensuring the cleaning effect of the spray nozzles 704 and scrapers 705.

[0036] Working principle: First, the filter press body 1 is connected to the water storage tank 2 via the connecting piece 10 and bolts. Then, the electric telescopic rod 801 pulls the movable plate 802 downward, causing it to move downward through multiple pairs of round rods 803, driving multiple spray nozzles 704 and scrapers 705 to penetrate into the interior of the filter press body 1. At the same time, multiple water pumps 701 draw water from the water storage tank 2 through the water guide pipe 702, flowing into the telescopic hose 703, and then spraying it outward through the spray nozzles 704, spraying it into the interior of the filter press body 1. Simultaneously, multiple scrapers 705 can scrape the interior of the filter press body 1, achieving simultaneous water spraying and scraping cleaning. When the movable plate 802 moves downward, a pair of auxiliary telescopic rods 901 move synchronously, driving a pair of movable hemispheres 902 to move along the inner wall of the L-shaped plate 3, and repeatedly interacting with multiple... When the fixed hemispheres 904 come into contact, the pair of movable hemispheres 902 are squeezed by the protruding outer walls of the multiple pairs of fixed hemispheres 904. With the assistance of the elastic displacement of the auxiliary telescopic rod 901 and the spring 903, the pair of movable hemispheres 902 are driven to repeatedly separate and collide with the inner wall of the L-shaped plate 3, generating vibration. This vibration is transmitted to the movable plate 802 and the multiple pairs of round rods 803 through the auxiliary telescopic rod 901, causing the solid particles remaining on the spray nozzle 704 and scraper 705 connected to them to fall off under the action of vibration, achieving a thorough cleaning. Then, the water that falls off after cleaning is filtered and adsorbed by the activated carbon filter plate 4 to remove the fixed particles and odors, so that the water is clean again for recycling. After cleaning, the filter press body 1 is disassembled and separated from the water storage tank 2 by the connecting piece 10 and the bolts.

[0037] The wiring diagrams for the filter press body 1, water pump 701, and electric telescopic rod 801 in this solution are common knowledge in the field. Their working principles are well-known technologies, and the appropriate models are selected based on actual use. Therefore, the control methods and wiring layouts for the filter press body 1, water pump 701, and electric telescopic rod 801 will not be explained in detail.
