Description

Technical Field

[0001] This application relates to cleaning equipment, and more particularly to a cleaning device for diatomaceous earth filter discs. Background Technology

[0002] Diatomaceous earth filtration equipment is widely used in fluid filtration industries such as food, chemical, and pharmaceutical. The core filtration component is the filter disc. During long-term operation, the resin in the fluid continuously mixes with the diatomaceous earth and adheres to the mesh pores of the filter disc, easily causing mesh blockage. This significantly reduces the permeability and filtration accuracy of the filter disc, directly leading to a decrease in the overall filtration effect, reduced filtration efficiency, and substandard product filtration quality.

[0003] Currently, the industry primarily relies on manual cleaning to clean clogged diatomaceous earth filter discs, which has several unavoidable drawbacks: First, the mixture of diatomaceous earth and resin creates highly adhesive dirt, making it difficult to thoroughly remove deep-seated impurities from the mesh through manual wiping and rinsing. This results in poor cleaning effectiveness, with residual clogging remaining after cleaning and inadequate filtration performance recovery. Second, manual cleaning requires the use of acetone chemical cleaning solution, which has a pungent odor and creates a harsh working environment. Long-term operation can damage the health of operators, leading to poor work tolerance and high turnover rates. Third, manual cleaning is cumbersome, labor-intensive, and limits the number of items that can be cleaned per person per session, resulting in extremely low cleaning efficiency. This makes it unsuitable for the maintenance needs of industrialized mass production equipment and severely restricts the normal operation of production lines. Fourth, there are no standardized recycling channels for wastewater and waste generated during manual cleaning. Direct discharge of these materials can lead to material waste and environmental pollution, resulting in low resource utilization.

[0004] Currently, there is no dedicated automated cleaning equipment for diatomaceous earth filter discs. The industry urgently needs a dedicated cleaning equipment that is highly automated, thoroughly cleans, safe and environmentally friendly, and suitable for batch operations, to replace manual cleaning and solve many of the pain points of existing technologies.

[0024] The technical solutions of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Combination Figure 1-3 As shown, the cleaning device 100 for diatomaceous earth filter discs includes:

[0026] The acetone cleaning module includes a feeding platform 101 with diatomaceous earth filter discs. A cleaning tank 102 is formed behind the feeding platform 101. Two rows of roller brush assemblies are symmetrically arranged inside the cleaning tank 102. Each row of roller brush assemblies includes multiple roller brushes 103 arranged horizontally side by side. A horizontal channel 119 is formed between the two rows of roller brush assemblies for the diatomaceous earth filter discs to pass through. The horizontal channel 119 extends to the feeding platform 101. A row of circulating spray pipes 104 is formed above the area between two adjacent roller brushes 103. The circulating spray pipes 104 spray acetone solution.

[0027] The clean water cleaning module includes a conveyor roller platform 105 supported behind the horizontal channel 119, and multiple rows of clean water spray pipes 106 are formed above the conveyor roller platform 105.

[0028] In this embodiment, the diatomaceous earth filter discs are sequentially passed through the feeding platform, the cleaning tank, and the conveyor roller platform, and then subjected to high-pressure rinsing and roller brushing, followed by cleaning with clean water. During the high-pressure cleaning, acetone solution is used to effectively clean the highly adhesive diatomaceous earth filter discs. This mechanism requires almost no manual labor and realizes automated conveying of filter discs, brush cleaning, spray rinsing, repeated fine washing, and integrated recycling of wastewater and waste materials, while ensuring operational safety and improving cleaning quality and operational efficiency.

[0029] Furthermore, a circulation tank 107 is formed at the bottom of the cleaning tank 102. The acetone solution sprayed in the cleaning tank 102 is collected in the circulation tank 107 and circulated to the circulation spray pipe 104 by the pump 108.

[0030] In this embodiment, the acetone solution needs to be recycled and reused. The roller brush and spray are set inside the chassis to prevent the acetone solution from leaking out and to achieve circulating spray cleaning.

[0031] Furthermore, the pump 108 is connected to the circulating spray pipe 104 and the cleaning tank 102 by on-off valves 109 respectively.

[0032] In this embodiment, it is used to control opening and closing.

[0033] Furthermore, a grating sensing PLC system 110 is installed at the entrance and exit of the horizontal channel 119, respectively.

[0034] In this embodiment, it is possible to sense whether the disc is entering or leaving. Since the equipment cannot occupy too much space, the size of the cleaning tank needs to be limited. This means that the disc needs to be rolled back and forth and high-pressure cleaned multiple times to be thoroughly cleaned. Therefore, a grating sensor PLC needs to be set up. After sensing the disc, the roller can be reversed and moved in the opposite direction multiple times to achieve thorough cleaning of the disc.

[0035] Furthermore, a collection chamber 111 is formed below the conveyor roller platform 105. The collection chamber 111 collects the wastewater and waste materials after the water spraying and collects them into the recycling box 113 via the chute 112.

[0036] In this embodiment, the water used for rinsing cannot be reused for spraying; it must be collected and processed separately.

[0037] Furthermore, a clean water tank 114 is provided below the conveyor roller platform 105, and the second pump 115 pumps clean water to the clean water spray pipe 106 for output through pipeline.

[0038] In this embodiment, the device is specifically modularized, and the corresponding functions are achieved by assembling multiple modules.

[0039] Furthermore, the conveying roller platform 105 includes a plurality of rotating rollers 116 arranged side by side, and the diameter of the diatomaceous earth filter disc is greater than twice the distance between two adjacent rotating rollers 116.

[0040] In this embodiment, since there is a certain distance between the two rollers, in order to prevent the disc from falling, theoretically the diameter of the disc should be larger than the distance between the two rollers to prevent the risk of the disc falling. In practice, the diameter of the disc is 400-500mm and the gap between the rollers is 100-200mm.

[0041] Furthermore, the gap between two adjacent roller brushes 103 is only wide enough for the brush bristles to pass through.

[0042] In this embodiment, since the horizontal passage is actually the distance between the two rows of roller brush assemblies, the disc is driven forward by the rotation of the roller brushes. In order to prevent the disc from getting stuck between the two roller brushes, there is almost no gap between the roller brushes, that is, only the brush bristles can pass through.

[0043] Furthermore, the roller brushes 103 of the same row of roller brush assemblies rotate in the same direction, while the roller brushes 103 of the two rows of roller brush assemblies rotate in opposite directions, and the diatomaceous earth filter disc moves back and forth multiple times within the horizontal channel 119.

[0044] In this embodiment, for example Figure 3 In terms of direction, the upper row of rollers initially moves clockwise, and the lower row moves counterclockwise. This way, the disc is brushed while being moved forward. When it reaches the exit of the horizontal channel, the upper and lower rows of rollers move in opposite directions simultaneously, brushing and retracting the disc. After repeating this process multiple times, the disc is output.

[0045] Furthermore, a support 117 is provided below the conveyor roller platform 105, and a cover 118 is provided above the feeding platform 101 and the conveyor roller platform 105, respectively.

[0046] In this embodiment, the equipment is protected and danger is prevented. Furthermore, the diffusion of gas, namely acetone chemical cleaning solution, can be reduced to a certain extent to prevent spillage.

[0047] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
