Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to a factory production sewage treatment device. Background Art

[0002] After use, purified water changes its physical and chemical properties, becoming wastewater containing various impurities. Chemical wastewater is wastewater discharged from chemical production, including process wastewater, cooling water, exhaust gas scrubbers, and equipment and site wash water. If discharged without treatment, these wastewaters can cause varying degrees of contamination, endangering human health and impacting industrial and agricultural production. Existing chemical wastewater filtration equipment generally relies on chemical treatment, which can easily generate additional pollutants and complicate the treatment process.

[0003] Chinese patent application number CN215946959U discloses a chemical production wastewater treatment device, which includes a filter box, a reaction box, a water inlet on the filter box, a drain outlet on the reaction box, and a primary filter plate inside the filter box. It also includes a cleaning device and a mixing device. This device can perform preliminary filtration on the wastewater, which helps to increase the subsequent chemical reaction rate and thus improve the wastewater purification efficiency.

[0004] However, the above scheme still has certain shortcomings. The scheme lacks the process of static sedimentation of sewage, and is directly filtered through the filter plate, which increases the filtration pressure of the filter plate and is not sufficient. As a result, the sewage that is not sufficiently filtered will directly participate in the subsequent mixing process, resulting in poor dosing and mixing effects. At the same time, the filter plate of this scheme is only cleaned on one side, and the filter plate is not cleaned sufficiently, which can easily affect the filtration effect. The impurities after cleaning are difficult to recover and are easily mixed into the water again. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0023] See Figure 1-Figure 3 , the utility model provides a technical solution:

[0024] like Figure 1-Figure 3 As shown, a factory produces sewage treatment equipment, including a water inlet 1, a water storage tank 2, a filter box 4, a mixing box 6 and a water outlet 7, the water inlet 1 is located at the bottom of one side of the water storage tank 2, a first connecting port 3 is provided between the water storage tank 2 and the filter box 4, the first connecting port 3 is located at the top of the water storage tank 2, a second connecting port 5 is provided between the filter box 4 and the mixing box 6, and the water outlet 7 is located on one side of the bottom of the mixing box 6; a filter plate 9 and a cleaning assembly 8 are provided in the filter box 4, and the cleaning assembly 8 includes two groups of collecting boxes 81 symmetrically arranged about the filter plate 9, a roller brush 82 is provided in the collecting box 81, and the two collecting boxes 81 are connected by a connecting frame 83, and the connecting frame 83 is an inverted U-shaped structure. A telescopic cylinder 85 is provided on both sides of the connection, and the cylinder seat of the telescopic cylinder 85 is fixed to the outer wall of the filter box 4, and the piston rod of the telescopic cylinder 85 is connected to both sides of the top of the connecting frame 83.

[0025] Through the above technical solution, sewage enters the water tank 2 through the water inlet 1. Since the first connecting port 3 between the water tank 2 and the filter box 4 is located at the top of the water tank 2, the water level of the water tank 2 needs to reach the first connecting port 3 before it can flow into the filter box 4. During this process, the sewage in the water tank 2 is allowed to settle to a certain extent, so that large particles of impurities in the sewage will remain in the filter box 4, reducing the filtering pressure of the filter plate 9 in the filter box 4 and improving the subsequent filtering effect of the filter plate 9.

[0026] The sewage in the filter box 4 is filtered through the filter plate 9, and the impurities generated by the filtration are adsorbed on the sieve holes of the filter plate 9. At this time, the collection boxes 81 on both sides are attached to the two sides of the filter plate 9. Since the two collection boxes 81 are connected by a connecting frame 83, and the connecting frame 83 is connected to the telescopic cylinder 85, the telescopic cylinder 85 drives the connecting frame 83 and the collection box 81 to move up and down, so that the roller brush 82 in the collection box 81 continuously brushes both sides of the filter plate 9. At the same time, the impurities brushed off will be stored in the collection box 81, which is convenient for subsequent treatment of impurities and prevents impurities from continuing to follow the filtered water flow into the next treatment process.

[0027] The water filtered by the filter plate 9 enters the mixing box 6 through the second connecting port 5 to be mixed with the medicine, and finally the purified water flows out through the water outlet 7.

[0028] Furthermore, the width of the collecting box 81 is adapted to the width of the filter box 4 , and both ends of the roller brush 82 are rotatably connected to the inner wall of the collecting box 81 , and the roller brush 82 abuts against the filter plate 9 .

[0029] Through the above technical solution, the width of the collecting box 81 is adapted to the width of the filter box 4, that is, the width of the collecting box 81 is adapted to the width of the filter plate 9. The collecting box 81 is driven up and down by the telescopic cylinder 85, so that the collecting box 81 can cover the filter plate 9. When the collecting box 81 moves through the telescopic cylinder 85, the internal roller brush 82 abuts against the filter plate 9, causing the roller brush 82 to rotate, and the filter plate 9 is continuously cleaned by the roller brush 82, so that the roller brush 82 can clean as much of the filter plate 9 as possible, and at the same time, the impurities cleaned can be collected by the collecting box 81.

[0030] Furthermore, the collecting box 81 is detachably connected to the connecting frame 83 , and a brush 84 is provided on the end surface of the collecting box 81 that contacts the filter plate 9 .

[0031] Through the above technical solution, the end surface of the collection box 81 that contacts the filter plate 9 is provided with a circle of brushes 84. The brushes 84 can assist in cleaning. At the same time, the contact between the brushes 84 and the filter plate 9 can prevent impurities in the collection box 81 that have been swept away by the roller brush 82 from flowing out of the collection box 81, thereby providing a certain degree of water filtering. After the filter plate 9 is cleaned, the collection box 81 is lifted out of the filter box 4 by the telescopic cylinder 85. Since the collection box 81 is detachably connected to the connecting frame 83, the collection box 81 can now be removed for cleaning.

[0032] Furthermore, the lifting height of the telescopic cylinder 85 is the same as the height of the filter box 4 .

[0033] Through the above technical solution, when the roller brush 82 is not cleaned, the telescopic cylinder 85 is at the maximum lifting height, and the collection box 81 and the connecting frame 83 are pushed out to the top of the filter box 4 through the telescopic cylinder 85; when the telescopic cylinder 85 contracts, the collection box 81 and the connecting frame 83 gradually fall into the filter box 4 until the contraction cylinder is completely retracted, and the bottom of the collection box 81 is in contact with the bottom of the filter box 4.

[0034] Furthermore, the height of the filter plate 9 is the same as the height of the filter box 4 .

[0035] Through the above technical solution, the filter plate 9 and the filter box 4 have the same height and width, so that sewage can only enter the other side through the filter plate 9.

[0036] Furthermore, the volume of the filter box 4 is smaller than that of the water storage tank 2 , and the filter box 4 , the water storage tank 2 and the mixing box 6 are at the same height.

[0037] Through the above technical solution, the filter box 4 is supported by the columns to the same height as the water tank 2, and the first connecting port 3 and the second connecting port 5 are at the same height.

[0038] Furthermore, a multi-blade stirring shaft 61 is provided in the stirring box 6 , and a drug feeding port 62 is provided on the top of the stirring box 6 .

[0039] Through the above technical solution, the medicine and sewage can be conveniently mixed fully through the multi-blade stirring shaft 61, thereby improving the mixing effect.

[0040] Furthermore, the water inlet 1 and the water outlet 7 are both provided with valves.

[0041] Through the above technical solution, both the water inlet 1 and the water outlet 7 are provided with one-way valves to prevent water from flowing back.

[0042] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant field. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention shall be protected by the claims appended hereto.
