Description

Technical Field

[0001] This utility model relates to the field of paper tape filter technology, specifically a vacuum paper tape filter for pretreatment of degreasing liquid in automotive coatings. Background Technology

[0002] In the field of paper belt filter processing, paper belt filters are widely used in the purification, treatment and recycling of machine tool fluids such as cutting fluids or grinding fluids because they have higher filtration accuracy and a higher degree of automation compared to other particulate matter separation methods.

[0003] However, current paper belt filters still have some problems in use. Usually, wastewater is poured directly onto the paper belt, causing impurities in the wastewater to be loosely distributed on the paper belt. Subsequently, the paper belt is circulated and transported by the conveying mechanism to filter the wastewater. However, this method results in low utilization of the paper belt and impurities on the paper belt of varying thicknesses, resulting in only average filtration capacity for wastewater. To address these issues, we propose a vacuum paper belt filter for the pretreatment of automotive coating degreasing fluid. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum paper tape filter for pretreatment of automotive coating degreasing solution, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum paper tape filter for pretreatment of automotive coating degreasing liquid, comprising a housing, a steel mesh motor mounted on the housing, a steel mesh transmission mechanism driven by the steel mesh motor, the steel mesh transmission mechanism for conveying the paper tape, a belt sealing mechanism on one side of the steel mesh transmission mechanism, a drain pump mounted on the outside of the housing, the housing and the drain pump connected by a pipe, a filter paper roll mounted on the housing, a wastewater diversion box mounted above the housing, a wastewater sensor mounted on the wastewater diversion box, a water purifier mounted on the outside of the housing, a vacuum fan fixedly mounted on the housing, the suction pipe end of the vacuum fan fixedly connected to the inside of the housing, the exhaust pipe end of the vacuum fan positioned above the steel mesh transmission mechanism, a collection box mounted on one side of the exhaust pipe, and an electrical control box mounted on the housing.

[0009] As a further preferred embodiment of this technical solution, the circular holes are equally spaced at the lower outer side of the diversion pipe, and the diversion pipe is equally spaced on the outer side of the transverse pipe.

[0010] This utility model provides a vacuum paper tape filter for pretreatment of automotive paint degreasing solution, which has the following advantages: This invention introduces wastewater into a wastewater diversion box, where it is dispersed above a steel mesh transmission mechanism. The wastewater is poured onto a paper tape, and a vacuum fan draws air from the box, reducing the internal pressure and accelerating the flow of liquid from the filter cloth into the box. This negative pressure significantly increases the transport capacity of the filter medium, and the formation of a large amount of filter cake improves the utilization rate of the filter medium. The filter cake forms an additional, high-quality filter layer, thereby enhancing filtration capacity and efficiency. Simultaneously, the hot air from the vacuum fan dries the contaminated filter cloth, allowing contaminant particles adhering to it to detach and fall into the collection box for effective collection.

[0011] This invention features a belt sealing mechanism and a specially structured rubber sealing plate that forms a seal between the bottom and the filter paper, and a seal between the side and the housing. An automatically adjustable spring ensures a good seal between the rubber sealing plate and the filter paper, while also allowing the filter paper to move forward. This bidirectional seal provides a better sealing effect, preventing fine pollutant particles from leaking from the side.

[0012] This utility model features a wastewater diversion box. As wastewater enters the vertical pipe, it passes through the horizontal pipe and is then dispersed within the diversion pipe. Through the cooperation of the round hole and the guide hole, the wastewater can be diverted and guided, allowing it to be evenly poured onto the paper tape. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] This utility model provides a technical solution as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in this embodiment, a vacuum paper tape filter for pretreatment of automotive paint degreasing solution includes a housing 1. A steel mesh motor 2 is mounted on the housing 1, and a steel mesh transmission mechanism 3 is driven by the steel mesh motor 2. The steel mesh transmission mechanism 3 is used for conveying the paper tape. A belt sealing mechanism 4 is provided on one side of the steel mesh transmission mechanism 3. A drain pump 5 is provided on the outside of the housing 1. The housing 1 and the drain pump 5 are connected by a pipe. A filter paper roll 6 is mounted on the housing 1. A sewage diversion box 7 is provided above the housing 1. A sewage sensor 8 is provided on the sewage diversion box 7. A water purifier 9 is provided on the outside of the housing 1. A vacuum fan 10 is fixedly mounted on the housing 1. The end of the suction pipe 11 of the vacuum fan 10 is fixedly connected to the inside of the housing 1. The end of the exhaust pipe 12 of the vacuum fan 10 is... Above the steel mesh transmission mechanism 3, a collection box 14 is provided on one side of the exhaust pipe 12. An electrical control box 13 is provided on the box body 1. Sewage enters the sewage diversion box 7 and is dispersed above the steel mesh transmission mechanism 3. The sewage is poured onto the paper tape. The vacuum fan 10 draws air from the box body 1, reducing the internal pressure of the box body 1 and accelerating the flow of liquid on the filter cloth to the box body 1. The negative pressure can greatly increase the conveying capacity of the medium. Furthermore, the formation of a large amount of filter cake increases the utilization rate of the filter medium. The formed filter cake constitutes an additional high-quality filter layer, thereby improving the filtration capacity and efficiency. At the same time, the hot air from the vacuum fan 10 can dry the contaminated filter cloth, allowing the contaminant particles stuck to the filter cloth to fall off and be effectively collected inside the collection box 14.

[0017] like Figure 2 and Figure 3 As shown, the belt sealing mechanism 4 includes a belt strip 15, a rubber sealing plate 16 tightly attached to the belt strip 15, a U-shaped plate 17 fixedly installed on the outer side of the rubber sealing plate 16, a column 18 fixedly installed on the U-shaped plate 17, the column 18 inserted into the inside of the fixing sleeve 19, the fixing sleeve 19 fixedly installed on the connecting plate 20, the connecting plate 20 fixedly set inside the box 1, a spring 21 sleeved on the outer side of the column 18, and the U-shaped plates 17 arranged sequentially on the outer side of the rubber sealing plate 16. The rubber sealing plate 16 tightly adheres to the inner wall of the box 1. With the belt sealing mechanism 4, the specially structured rubber sealing plate 16 forms a seal with the filter paper at the bottom and a seal with the box 1 on the side. Through the automatically adjustable spring 21, a good seal is formed between the rubber sealing plate 16 and the filter paper, which also ensures that the filter paper can move forward. This bidirectional seal can form a good sealing effect, preventing fine pollutant particles from leaking from the side.

[0018] like Figure 1 and Figure 4As shown, the sewage diversion box 7 includes an inlet tank 22, a vertical pipe 23 fixedly installed inside the inlet tank 22, a horizontal pipe 24 fixedly installed at the bottom end of the vertical pipe 23, a diversion pipe 25 fixedly installed on the outside of the horizontal pipe 24, a circular hole 26 opened on the outside of the diversion pipe 25, a guide hole 27 opened at the bottom of the inlet tank 22, the guide holes 27 are evenly distributed on the inlet tank 22, the circular holes 26 are evenly opened at the lower position on the outside of the diversion pipe 25, and the diversion pipe 25 is evenly arranged on the outside of the horizontal pipe 24. With the sewage diversion box 7, as sewage enters the interior of the vertical pipe 23, it can pass through the interior of the horizontal pipe 24 and then be dispersed into the interior of the diversion pipe 25. Through the cooperation between the circular hole 26 and the guide hole 27, the sewage can be diverted and guided, so that the sewage can be evenly poured onto the paper tape.

[0019] This utility model provides a vacuum paper tape filter for pretreatment of automotive paint degreasing solution, and its specific working principle is as follows: During operation, the device operates by personnel via the electrical control box 13. The steel mesh motor 2 starts, driving the steel mesh transmission mechanism 3 to move. This allows the filter paper roll 6 to be laid on the steel mesh transmission mechanism 3 and move in position. Simultaneously, it activates the belt sealing mechanism 4, causing the belt strip 15 to move below the rubber sealing plate 16. The specially structured rubber sealing plate 16 forms a seal between its bottom and the filter paper, and a seal between its sides and the housing 1. Through an automatically adjustable spring 21, a good seal is formed between the rubber sealing plate 16 and the filter paper, ensuring the filter paper can move forward. This bidirectional seal provides a good sealing effect, preventing fine pollutant particles from leaking from the sides. Wastewater then enters the vertical pipe 23, passes through the horizontal pipe 24, and is then dispersed into the diversion pipe 25. With the cooperation of the circular hole 26 and the guide hole 27, the sewage can be diverted and guided, so that the sewage can be evenly poured onto the paper tape. The sewage enters the sewage diversion box 7 and is dispersed above the steel mesh transmission mechanism 3. The sewage is poured onto the paper tape, and the vacuum blower 10 draws air from the box 1, which reduces the internal pressure of the box 1 and accelerates the flow of liquid on the filter cloth to the box 1. The negative pressure can greatly increase the conveying capacity of the medium, and the formation of a large amount of filter cake can improve the utilization rate of the filter medium. The formed filter cake constitutes an additional high-quality filter layer, thereby improving the filtration capacity and filtration efficiency. At the same time, the hot air from the vacuum blower 10 can dry the contaminated filter cloth, and the contaminant particles stuck on the filter cloth can fall off and fall into the collection box 14 for effective collection.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
