Description

Technical Field

[0001] This utility model relates to a spray tower base that is easy to maintain. Background Technology

[0002] In industrial coating processes (such as automobile manufacturing, furniture processing, and mechanical parts spraying), waste gas containing a large amount of paint mist particles is generated. Direct emission of this gas not only causes air pollution but also harms the health of operators. Therefore, specialized purification equipment is needed to treat the paint mist waste gas. Spray towers, as the current mainstream paint mist pretreatment equipment, are widely used in the waste gas treatment systems of coating production lines due to their advantages such as simple structure, low operating costs, and high paint mist capture efficiency.

[0003] The core structure of existing paint mist treatment spray towers typically includes a tower body, a spray system, a demister, and a water circulation system. During the spraying process, after the water interacts with the paint mist, it contains particulate impurities. Since the water is recycled, failing to filter it can damage the water pump. Furthermore, recirculating unfiltered water back into the spray tower to filter the paint mist reduces the filtration efficiency.

[0004] The existing water tank in the spray water circulation section is the part used for water treatment. The water tank is located at the bottom of the spray tower and has the same diameter as the spray tower. It is in a sealed state and can only be cleaned and maintained through a maintenance port. The diameter of the maintenance port is limited, making the operation quite troublesome. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art, thereby providing a spray tower base that is easy to maintain and has a good filtration effect on circulating water, while also being easy to clean and maintain the filter tank.

[0006] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0007] This utility model discloses a spray tower base that is easy to maintain, comprising a base and a filter tower located on the base; the base includes a circular and hollow primary water filter tank and a square and hollow secondary water filter tank; the primary water filter tank is located directly below the filter tower; a water discharge plate is provided in the middle of the primary water filter tank; a water discharge port is provided in the middle of the water discharge plate, and the water discharge plate is a "trumpet shape" that is wider at the top and narrower at the bottom, so that the water coming from the filter tower will flow out of the water discharge port more naturally.

[0008] Preferably, a support plate is distributed below the water discharge base plate to allow the water discharge base plate to be located inside the primary water filter tank; multiple support members are evenly distributed between the water discharge base plate and the edge of the primary water filter tank.

[0009] As a preferred option, a cover is also provided on the primary water filter tank.

[0010] Preferably, the secondary filter tank is located on one side of the primary filter tank; an outlet is provided on the wall of the primary filter tank at the connection between the primary and secondary filter tanks.

[0011] Preferably, a baffle is provided between the two filter screens a below the water discharge base plate.

[0012] Preferably, symmetrical filter screens a are provided on both sides of the inner side of the primary water filter bucket with the water outlet as the center.

[0013] Preferably, the secondary water filter tank is divided into a pre-water tank and a post-water tank; a filter screen b is provided between the pre-water tank and the post-water tank.

[0014] Preferably, filter a has an 8mm filter hole and filter b has a 3mm filter hole.

[0015] Preferably, motor cover plates are symmetrically arranged above the rear water tank for placing the motor.

[0016] Preferably, the bottom of the base is provided with crisscrossing reinforcing channel steel.

[0017] The beneficial effects of this utility model are:

[0018] This application divides the base (i.e., the water pool of the water circulation part of the same type of spray tower) into a primary water filter tank and a secondary water filter tank. The diameter of the primary water filter tank is larger than the diameter of the filter tower. Since the water after spraying will contain particulate impurities, these impurities will adhere to the inside of the primary water filter tank, requiring cleaning and maintenance. Traditionally, this part is located directly below the filter tower and can only be maintained and cleaned through the maintenance port. However, the primary water filter tank of this application can be easily maintained and cleaned by opening the cover.

[0019] In addition, the two-stage water filter design, along with filter screens a and b, allows the water to be better cleaned and filtered during circulation, ensuring the purity of the water during the circulation process. Attached Figure Description

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0027] like Figure 1-2 As shown in Figure 6, a spray tower base that is easy to maintain is mainly used to filter paint mist during painting operations and then discharge it to meet environmental protection standards.

[0028] The system includes a base 1 and a filter tower 3 located on the base 1. The filter tower 3 is the main part for filtering paint mist, and this part is the same as the prior art in this application, using the same principle. The base 1 includes a circular and hollow primary water filter tank 1.1 and a square and hollow secondary water filter tank 1.6. The primary water filter tank 1.1 is located directly below the filter tower 3. A water discharge plate 1.3 is provided in the middle of the primary water filter tank 1.1. More specifically, the filter tower 3 is vertically located above the water discharge plate 1.3, and both have the same diameter. A water discharge port 1.11 is provided in the middle of the water discharge plate 1.3, and the water discharge plate 1.3 is a "trumpet shape" with a larger top and a smaller bottom. This allows the water coming down from the filter tower 3 to flow out more naturally from the water discharge port 1.11 without obstruction or accumulation on the water discharge plate 1.3, allowing the water remaining in the filter tower 3 to enter the primary water filter tank 1.1.

[0029] See Figure 3-4As shown, a support plate 1.13 is distributed below the water discharge base plate 1.3 to place the water discharge base plate 1.3 inside the primary water filter tank 1.1; multiple support members 1.10 are evenly distributed between the edges of the water discharge base plate 1.3 and the primary water filter tank 1.1 to enhance the stability of the water discharge base plate 1.3, so that its bottom is supported by the support plate 1.13 and its top is supported by the support members 1.10 from the side.

[0030] A cover plate 1.2 is also provided on the primary water filter tank 1.1. Specifically, the cover plate 1.2 is placed on the support member 1.10 and covers the opening between the primary water filter tank 1.1 and the discharge bottom plate 1.3; that is, the diameter of the primary water filter tank 1.1 is larger than the diameter of the discharge bottom plate 1.3. Furthermore, this application enlarges the primary water filter tank 1.1 so that the water filter tank is on the outer ring of the filter tower 3, and a cover plate 1.2 is provided on top of it. This makes the later maintenance of the primary water filter tank 1.1 very convenient. In existing spray towers of the same type, the water filter tanks are all of the same diameter as the filter tower, and the water filter tanks can only be maintained and cleaned through a single maintenance port, which is very inconvenient; while in this application, cleaning can be easily carried out by simply opening the cover plate 1.2.

[0031] The secondary filter tank 1.6 is located on one side of the primary filter tank 1.1. An outlet 1.14 is provided on the wall of the primary filter tank 1.1 at the connection point between the primary and secondary filter tanks 1.1 and 1.6. This allows water from the primary filter tank 1.1 to flow into the secondary filter tank 1.6 through the outlet 1.14. Furthermore, the secondary filter tank 1.6 is semi-open, operating on the same principle as the primary filter tank 1.1, making maintenance and cleaning more convenient.

[0032] Below the water discharge base plate 1.3, a baffle 1.12 is provided between the two filter screens a1.8. Specifically, the entire primary water filter tank 1.1 is a cylindrical tank. After filter screens a1.8 are installed on both sides of the water outlet 1.14, the baffle 1.12 blocks the opening between the two filter screens a1.8, so the water in the entire primary water filter tank 1.1 can only flow out through the filter screens a1.8.

[0033] The inner side of the primary water filter tank 1.1 is equipped with symmetrical filter screens a1.8 on both sides centered on the outlet 1.14. Specifically, the filter screens a1.8 are located inside the primary water filter tank 1.1, that is, below the two supporting members 1.10. This makes the primary water filter tank 1.1 form a filtration structure. Since the primary water filter tank 1.1 has only one outlet 1.14, when the water in the primary water filter tank 1.1 is full to the position of the outlet 1.14, it will automatically flow into the secondary water filter tank 1.6. However, there are filter screens a1.8 on both sides of the outlet 1.14, which ensures that the water flowing from the primary water filter tank 1.1 to the secondary water filter tank 1.6 is filtered water, thus achieving a filtration function.

[0034] The secondary water filter tank 1.6 is divided into a pre-filter tank 1.4 and a post-filter tank 1.7. A filter screen b1.9 is installed between the pre-filter tank 1.4 and the post-filter tank 1.7. Specifically, when the water in the primary water filter tank 1.1 passes through the filter screen a1.8 and enters the secondary water filter tank 1.6, it first enters the pre-filter tank 1.4, and then passes through the filter screen b1.9 to enter the post-filter tank 1.7. In this way, the water entering the post-filter tank 1.7 has undergone two filtrations, the first by the filter screen a1.8 and the second by the filter screen b1.9, thus ensuring that most of the impurities in the water can be filtered out.

[0035] The filter screen a1.8 has an 8mm filter hole, and the filter screen b1.9 has a 3mm filter hole.

[0036] The rear water tank 1.7 is symmetrically equipped with motor cover plates 1.5 above it for housing the motor. Specifically, the working principle of the spray tower is that after the paint mist enters, it is washed by the water flow. In this way, most of the particulate impurities in the paint mist are carried away by the water flow. Then the paint mist enters the packing zone (the working principle of the existing spray tower is that the water is filtered first, and then it enters the packing zone for further filtration. The packing zone can be a filter material such as hollow balls. This is common knowledge and will not be described in detail by the applicant). The water used to filter the paint mist is recycled. It is sprayed from the bottom of the spray tower by the motor through a water pump. The recycled water also needs to be filtered, otherwise the impurities in the water will damage the water pump and affect the filtration effect of the spray tower.

[0037] See Figure 5 As shown, the bottom of the base 1 is provided with crisscrossing reinforcing channel steel 1.15 to support the base 1 and increase the load-bearing capacity of the base 1.

[0038] The beneficial effects of this utility model are:

[0039] This application divides the base (i.e., the water pool of the water circulation part of the same type of spray tower) into a primary water filter tank and a secondary water filter tank. The diameter of the primary water filter tank is larger than the diameter of the filter tower. Since the water after spraying will contain particulate impurities, these impurities will adhere to the inside of the primary water filter tank, requiring cleaning and maintenance. Traditionally, this part is located directly below the filter tower and can only be maintained and cleaned through the maintenance port. However, the primary water filter tank of this application can be easily maintained and cleaned by opening the cover.

[0040] In addition, the two-stage water filter design, along with filter screens a and b, allows the water to be better cleaned and filtered during circulation, ensuring the purity of the water during the circulation process.
