Description

Technical Field

[0001] This utility model relates to the field of emulsion processing technology, specifically to a waste liquid cleaning device in the processing of waterborne polyurethane emulsions. Background Technology

[0002] Waterborne polyurethane coatings are a type of green and environmentally friendly coating, but the production process still generates three types of waste: wastewater, waste gas, and solid waste. Among these, wastewater is the main source of pollution, containing large amounts of organic matter such as COD, BOD, and SS, as well as heavy metal ions. If discharged directly without treatment, it will cause serious environmental pollution.

[0003] In existing technologies, when cleaning emulsion wastewater, it is usually mixed directly with a certain amount of precipitant to cause the suspended particles in the wastewater to settle, thereby purifying the wastewater. However, since there are many impurities in the wastewater, direct sedimentation may increase the wastewater treatment time, thereby reducing work efficiency and having poor effect, making it inconvenient to use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a waste liquid cleaning device in the process of waterborne polyurethane emulsion processing, so as to solve the technical problems of low waste liquid cleaning efficiency and poor treatment effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste liquid cleaning device for the processing of waterborne polyurethane emulsions, comprising a fixed box, a plurality of support rods fixedly connected to the bottom of the fixed box, a feed pipe fixedly connected to one side of the outer wall of the fixed box, a through groove opened on the surface of the feed pipe, a movable rod movably sleeved on the inner wall of the through groove, a connecting plate fixedly connected to the bottom of the movable rod inside the feed pipe, a baffle fixedly connected to one side of the connecting plate, a slot matching the baffle opened on one side of the feed pipe on the through groove, a fixing block fixedly connected to one side of the top of the movable rod, a spring fixedly connected to the lower surface of the fixing block and fixedly connected to the upper surface of the feed pipe, a pull rod rotatably connected to the top of the movable rod, a limiting plate fixedly connected to the outer wall of the fixed box above the pull rod, an opening opened at the contact position between the feed pipe and the fixed box, and mounting blocks fixedly connected to both sides of the opening on the inner wall of the fixed box, and a filter screen movably installed between the two sets of mounting blocks.

[0006] By adopting the above technical solution, the baffle can be moved by pulling the rod in conjunction with the connecting plate, and the pulling rod is limited and fixed by the limiting plate. When the bottom end of the baffle separates from the bottom end of the inner wall of the feed pipe, the waste can enter the fixed box through the feed pipe. When the waste enters the fixed box, it is filtered by using a filter screen to remove impurities from the waste, thus facilitating subsequent waste processing. The operation is simple and convenient.

[0007] Furthermore, sealing gaskets are fixedly installed at the bottom ends of both the connecting plate and the baffle, and sliders are fixedly connected to both ends of the connecting plate. A groove matching the slider is opened on the inner wall of the feed pipe.

[0008] By adopting the above technical solution, the sealing gasket can be used to seal the connection between the baffle and the connecting block and the feed pipe, and the slider and the slide groove can limit the position of the connecting plate.

[0009] Furthermore, T-shaped blocks are fixedly connected to both ends of the filter screen, and spring retaining beads are fixedly connected to one side surface of the top of the T-shaped blocks. T-shaped grooves matching the T-shaped blocks are opened on one side surface of the two sets of mounting blocks, and connecting blocks are fixedly connected to the top of the two sets of mounting blocks. The spring retaining beads are movably engaged with the connecting blocks.

[0010] By adopting the above technical solution, the filter screen can be limited by the T-shaped block and the T-shaped groove, and the filter screen can be fixedly installed by the spring retaining ball.

[0011] Furthermore, a transmission assembly is movably connected inside the fixed box. The transmission assembly includes a second motor fixedly installed at the top of the outer wall of the fixed box. The output end of the second motor extends into the interior of the fixed box and is connected to a threaded rod via a coupling. Two sets of connecting rods are symmetrically fixedly connected to the outer wall of the bottom end of the threaded rod. A stirring rod is fixedly connected to the end of the connecting rod away from the threaded rod.

[0012] By adopting the above technical solution, the second motor can drive the stirring rod to rotate through the threaded rod, thereby facilitating the mixing of the precipitant and waste materials.

[0013] Furthermore, a movable plate is movably sleeved on the outer wall of the threaded rod, and a water guide block is fixedly connected to the lower surface of the movable plate. Multiple sets of nozzles are fixedly installed at the bottom end of the water guide block.

[0014] By adopting the above technical solution, the nozzle can be moved by the movable plate, which facilitates the cleaning of the inner wall of the fixed box.

[0015] Furthermore, a corrugated pipe connected to the water guide block is fixedly connected to the upper surface of the movable plate. The end of the corrugated pipe away from the water guide block extends to the outside of the fixed box and is fixedly connected to the external water pipe.

[0016] By adopting the above technical solution, water can be transmitted to the inside of the water guide block through the corrugated pipe, which facilitates the cleaning of the inner wall of the fixed box.

[0017] Furthermore, a scraper ring is fixedly connected to the outer wall of the movable plate by a fixing rod, and a limit groove is formed on the outer wall of the scraper ring. A limit rod matching the limit groove is fixedly connected to the inner wall of the fixed box.

[0018] By adopting the above technical solution, impurities adhering to the inner wall of the fixed box can be scraped off using a scraper ring, thereby facilitating the cleaning of the fixed box.

[0019] In summary, the present invention has the following beneficial effects: The present invention uses a pull rod and a connecting plate to move the baffle, which facilitates the entry of waste liquid into the fixed tank through the feed pipe. The baffle facilitates the quantitative control of the waste liquid entering the fixed tank. When the waste liquid enters the fixed tank, it is filtered through a filter screen to remove suspended particles and impurities from the water. In addition, a precipitant is used to achieve the purpose of purification, which improves the treatment effect and work efficiency of waste liquid to a certain extent. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] A waste liquid cleaning device for the processing of waterborne polyurethane emulsions, such as Figure 1-8 As shown, it includes a fixed box 100, with multiple sets of support rods 110 fixedly connected to the bottom of the fixed box 100, and a feed pipe 111 fixedly connected to one side surface of the outer wall of the fixed box 100, through which waste liquid can be discharged into the fixed box 100.

[0032] For example, a through groove 1111 is provided on the surface of the feed pipe 111, and a movable rod 112 is movably sleeved on the inner wall of the through groove 1111. The movable rod 112 can be limited by the through groove 1111.

[0033] For example, the bottom end of the movable rod 112 is fixedly connected to a connecting plate 113 inside the feed pipe 111, and a baffle 1132 is fixedly connected to one side surface of the connecting plate 113. The movable rod 112 can move the baffle 1132 by cooperating with the connecting plate 113, thereby making it easier to open the feed pipe 111 and facilitate the waste material to enter the fixed box 100.

[0034] For example, the surface of the feed pipe 111 is provided with a slot 1112 that matches the baffle 1132 on one side of the through groove 1111. The baffle 1132 can be limited by the slot 1112.

[0035] For example, a fixing block 114 is fixedly connected to one side surface of the top end of the movable rod 112, and a spring 1141 fixedly connected to the upper surface of the feed pipe 111 is fixedly connected to the lower surface of the fixing block 114. The setting of the spring 1141 facilitates the resetting of the baffle 1132.

[0036] For example, a pull rod 1142 is rotatably connected to the top of the movable rod 112, and a limiting plate located above the pull rod 1142 is fixedly connected to the outer wall of the fixed box 100. The pull rod 1142 can be used to pull the baffle 1132 to move, and the limiting plate can be used to limit the pull rod 1142.

[0037] For example, an opening is provided at the contact position between the feed pipe 111 and the fixed box 100, and mounting blocks 115 located on the inner wall of the fixed box 100 are fixedly connected to both sides of the opening. A filter screen 116 is movably installed between the two sets of mounting blocks 115. When waste enters the fixed box 100 through the feed pipe 111, the waste is filtered by the filter screen 116. The filter screen 116 can be installed by the mounting blocks 115.

[0038] In some examples, please refer to Figure 3 , Figure 4 , Figure 8 Both the connecting plate 113 and the baffle 1132 are fixedly installed with sealing gaskets at their bottom ends. The sealing gaskets facilitate the sealing of the contact points between the baffle 1132 and the connecting plate 113 and the feed pipe 111.

[0039] For example, both ends of the connecting plate 113 are fixedly connected to sliders 1131, and the inner wall of the feed pipe 111 is provided with a groove that matches the sliders 1131. The connecting plate 113 can be sealed by the sliders 1131 cooperating with the grooves.

[0040] In some examples, please refer to Figure 7 Both ends of the filter screen 116 are fixedly connected to T-shaped blocks 1161. A spring retaining bead 1162 is fixedly connected to one side of the top of the T-shaped block 1161. One side of the surface of the two sets of mounting blocks 115 is provided with a T-shaped groove 1152 that matches the T-shaped block 1161. The top of the two sets of mounting blocks 115 is fixedly connected to a connecting block 1151. The spring retaining bead 1162 is movably engaged with the connecting block 1151. The mutual cooperation between the T-shaped block 1161 and the T-shaped groove 1152 facilitates the limiting use of the filter screen 116. By engaging the spring retaining bead 1162 onto the connecting block 1151, the filter screen 116 can be fixedly installed.

[0041] In some examples, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 A transmission assembly 120 is movably connected inside the fixed box 100. The transmission assembly 120 includes a second motor 121 fixedly installed on the top of the outer wall of the fixed box 100. The output end of the second motor 121 extends into the interior of the fixed box 100 and is connected to a threaded rod 122 via a coupling. Two sets of connecting rods 123 are symmetrically fixedly connected to the outer wall of the bottom end of the threaded rod 122. A stirring rod 1231 is fixedly connected to the end of the connecting rod 123 away from the threaded rod 122. When the second motor 121 drives the threaded rod 122 to rotate forward, the threaded rod 122, in conjunction with the connecting rod 123, drives the stirring rod 1231 to rotate, thereby facilitating the stirring of the waste liquid and the precipitant and accelerating the reaction rate.

[0042] In some examples, please refer to Figure 5 and Figure 6 A movable plate 124 is movably sleeved on the outer wall of the threaded rod 122. A water guide block 125 is fixedly connected to the lower surface of the movable plate 124. Multiple sets of nozzles 1251 are fixedly installed at the bottom of the water guide block 125. The nozzles 1251 can be moved and used by the movable plate 124. Water is sprayed out by the nozzles 1251, which facilitates rinsing the inner wall of the fixed box 100.

[0043] In some examples, please refer to Figure 5 and Figure 6 A corrugated pipe 127 connected to the water guide block 125 is fixedly connected to the upper surface of the movable plate 124. The end of the corrugated pipe 127 away from the water guide block 125 extends to the outside of the fixed box 100 and is fixedly connected to the external water pipe. Water can be transmitted to the inside of the water guide block 125 by using the corrugated pipe 127, which facilitates cleaning of the inner wall of the fixed box 100.

[0044] In some examples, please refer to Figure 5 and Figure 6 The outer wall of the movable plate 124 is fixedly connected to a scraper ring 126 by a fixing rod. The scraper ring 126 can scrape off the impurities adhering to the inner wall of the fixed box 100, thereby facilitating the cleaning and use of the fixed box 100.

[0045] For example, a limiting groove 1261 is provided on the outer wall of the scraper ring 126, and a limiting rod that matches the limiting groove 1261 is fixedly connected to the inner wall of the fixing box 100. The scraper ring 126 can be limited by the limiting groove 1261 and the limiting rod.

[0046] The working principle of this utility model is as follows: When in use, the connecting plate 113 is pulled by the pull rod 1142 in conjunction with the movable rod 112. The connecting plate 113 drives the baffle 1132 to move upward. By rotating the pull rod 1142, the pull rod 1142 is limited by the limiting plate, so that the waste material can enter the fixed box 100 through the feed pipe 111.

[0047] Furthermore, when waste enters the fixed box 100, it is filtered through the filter screen 116 to remove impurities. When the filter screen 116 needs to be replaced or cleaned, the filter screen 116 can be disassembled and used by pulling the filter screen 116 upward to separate the spring retaining ball 1162 from the connecting block 1151.

[0048] Furthermore, after the waste enters the fixed box 100, the second motor 121 is started, which drives the threaded rod 122 to rotate forward. The threaded rod 122, through the connecting rod 123, drives the stirring rod 1231 to rotate, thereby facilitating the stirring of the precipitant and the waste. After the impurities in the waste settle, the purified waste can be discharged.

[0049] Secondly, after the waste is discharged, when the threaded rod 122 is reversed by the second motor 121, the movable plate 124 descends, and the water source is transmitted to the water guide block 125 through the corrugated pipe 127. Then, the water is sprayed on the inner wall of the fixed box 100 through the nozzle 1251, which facilitates the cleaning of the fixed box 100. At the same time, the movable plate 124 drives the scraper ring 126 to descend, and the scraper ring 126 scrapes off the impurities adhering to the inner wall of the fixed box 100, which further cleans the fixed box 100 and facilitates its subsequent treatment of waste liquid.
