Description

Technical Field

[0001] This utility model belongs to the field of coating-related technology, and in particular relates to an extraction and filtration device for water-based coating additives. Background Technology

[0002] Water-based coatings use water as a solvent or dispersion medium. They are a relatively new type of coating on the market and include three types: water-soluble coatings, water-dilutable coatings, and water-dispersible coatings (latex coatings). Water-based coatings use water-soluble resins as film-forming agents, with polyvinyl alcohol and its various modified forms being representative examples. Other types include water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. During the production of water-based coatings, various media, solutions, and additives need to be added. These additives and other auxiliary materials require filtration before mixing to prevent impurities and particulate matter from affecting the quality of the final product. However, the following drawbacks still exist in actual filtration operations: Firstly, when processing large quantities of water-based coating additives, it is necessary to transfer the additives from the container storing the large amount of additives to the corresponding filtration device. Usually, filter media such as filter screens are used for filtration. However, conventional filtration methods are limited and at most multiple layers of filter screens are used for multi-stage filtration, which cannot filter out each critical part. Secondly, some conventional filter components, after filtering out impurities, make it difficult to know the quality of the filtered impurities due to the continuous delivery and filtration of additives, and cannot be cleaned in time. Furthermore, fixed filter components also have difficulty cleaning the filtered impurities. Utility Model Content

[0003] The purpose of this utility model is to provide a water-based coating additive extraction and filtration device. By setting up a filtration component, a pretreatment component, a screw, a storage tank, and a cross-shaped structure, it solves the problems of conventional filtration methods being singular, centralized, unable to filter key areas, and unable to know the amount of impurities filtered out in a timely manner, making timely cleaning impossible.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a water-based coating additive extraction and filtration device, including a storage tank, a cross, a water pump, a pretreatment component and a filtration component. An L-shaped bracket is fixed to the outer periphery of the storage tank. The horizontal part of the bracket is located above the storage tank, and a screw is threaded through the horizontal part of the bracket. A cross is set above the storage tank below the screw. A base plate is fixed to the bottom of the cross, and a filtration component is set below the base plate. The filter assembly includes a ring frame and hanging rings fixed above the ring frame in a ring array. The bottom of the ring frame is fixed with hook-shaped support rods in a ring array, and a filter screen is fixed to the bottom of the ring frame inside all the support rods. The bottom surface of the filter screen is conical, and the tops of the hooks of all the support rods are connected and fixed. The bottom edge of the base plate is fixed with hooks arranged in a circular array, and the hooks are connected to the hanging rings below them.

[0005] Furthermore, a support plate is fixed to the lower outer periphery of the storage tank, a water pump is fixed to the support plate, a liquid extraction pipe is fixed to the water pump's pumping pipe, a liquid outlet pipe is fixed to the water outlet end of the water pump, and the end of the liquid outlet pipe away from the water pump passes through the bottom plate and extends into the filter assembly.

[0006] Furthermore, a pretreatment assembly is connected to the end of the extraction tube away from the water pump. The pretreatment assembly includes a cap that is threadedly connected to the extraction tube, and a filter basket is fixed to the bottom of the cap.

[0007] Furthermore, the diameter of the base plate is smaller than the inner diameter of the storage tank, and the length of the cross is greater than the diameter of the storage tank; a limit rod is fixed at the bottom of each cross at the opposite end, and a limit groove is provided in the storage tank in a circular array, with the limit rod inserted into the limit groove.

[0008] Furthermore, each of the cross sections has an L-shaped bent rod fixed to its top at the opposite end. The vertical part of the bent rod is fixed to the cross section, and the horizontal part of the bent rod is connected to a round head. The bottom end of the screw is rotatably connected to the round head, and a handwheel is fixed to the top end of the screw.

[0009] Furthermore, a dispersing motor is fixed at the center of the top surface of the cross, the output shaft of the dispersing motor passes through the cross and the base plate and is fixed with a dispersing disk, and blades arranged in a ring array are fixed on the outer periphery of the dispersing disk, the dispersing disk and the blades are located inside the filter assembly.

[0010] This utility model has the following beneficial effects: This invention solves the problem of conventional filtration methods being singular and centralized, failing to filter key areas, by setting up a filtration component and a pretreatment component. When extracting water-based coating additives, the extraction pipe and pretreatment component are placed inside the additive storage container, eliminating the need to dump the additives. The pretreatment component performs preliminary filtration on the additives extracted by the pump, preventing large particles from entering the pump impeller and damaging it. Next, the delivered additives enter the filtration component in the storage tank for secondary filtration. The filter screen has a cylindrical structure with an open top and a conical bottom, allowing filtration on both the bottom and sides. This large filtration area enables multi-point filtration and diversified filtration methods, significantly extending the device's service life.

[0011] This invention solves the problem of not being able to know the amount of filtered impurities in a timely manner and not being able to clean them in a timely manner by setting up a screw, storage tank, cross, and filter assembly. The filter assembly is installed below the cross, and the screw lifts the cross to suspend it, thus suspending the filter assembly. During filtration, it will not come into contact with the additives in the storage tank. The impurities filtered out in the filter assembly accumulate in the filter screen. Because the filter assembly is suspended, only a slight rotation of the screw is needed to raise the cross and the filter assembly, so that the accumulation of impurities in the filter assembly can be observed, and a new filter assembly or impurities can be replaced in a timely manner. The filter assembly can be removed by taking the lifting ring off the hook at the bottom of the base plate. 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] Please refer to Figure 8. This utility model is a water-based coating additive extraction and filtration device, including a storage tank 1, a cross 2, a water pump 3, a pretreatment component 4, and a filtration component 5. An L-shaped bracket 101 is fixed to the outer periphery of the storage tank 1. The horizontal part of the bracket 101 is located above the storage tank 1, and a screw 102 is threadedly connected through the horizontal part of the bracket 101. A cross 2 is set above the storage tank 1 below the screw 102. A base plate 201 is fixed to the bottom of the cross 2, and the filtration component 5 is set below the base plate 201. The storage tank 1 is used to store the filtered additives. The screw 102 is installed using the bracket 101. The rotation of the screw 102 can drive the height of the cross 2 to rise or fall, thereby changing the height position of the cross 2 and the filter assembly 5. The filter assembly 5 includes a ring frame 501 and hanging rings 5011 fixed above the ring frame 501 in a ring array. The bottom of the ring frame 501 is fixed with hook-shaped support rods 503 in a ring array. A filter screen 502 is fixed to the bottom of the ring frame 501 inside all the support rods 503. The bottom surface of the filter screen 502 is conical. The tops of the hooks of all the support rods 503 are connected and fixed. In the filter assembly 5, the ring frame 501 is used as the main body, and a large number of hook-shaped support rods 503 are used for support. The filter screen 502 is installed inside the support rods 503 and below the ring frame 501 to form a cylindrical basket structure with an open top. The bottom surface is set as a cone shape, which facilitates filtration of a larger area and also facilitates the accumulation of impurities. It prevents impurities from quickly covering the bottom surface of the filter screen 502, while increasing the pressure resistance of the filter screen 502 and enhancing the structural strength. A series of hooks 205 arranged in a circular array are fixed at the bottom edge of the base plate 201, and the hooks 205 are connected to the lifting rings 5011 below them. Hooks 205 are distributed at the bottom of the base plate 201 to hook the hanging ring 5011 in the filter assembly 5, so that it is suspended in the air. While ensuring stable hanging, it also ensures sufficient disassembly effect, making it convenient to clean impurities or replace the filter assembly 5 in a timely manner. The operation is convenient and simple.

[0017] A support plate 103 is fixed to the lower part of the outer periphery of the storage tank 1. A water pump 3 is fixed on the support plate 103. A liquid extraction pipe 301 is fixed to the water extraction pipe of the water pump 3. A liquid outlet pipe 302 is fixed to the water outlet end of the water pump 3. The end of the liquid outlet pipe 302 away from the water pump 3 passes through the bottom plate 201 and extends into the filter assembly 5. Using the operation of the water pump 3, the external additives are extracted through the extraction pipe 301 and then transported out through the outlet pipe 302 to the filter assembly 5 for filtration.

[0018] The end of the extraction pipe 301 away from the water pump 3 is connected to a pretreatment component 4. The pretreatment component 4 includes a cap 401 threadedly connected to the extraction pipe 301, and a filter basket 402 is fixed to the bottom of the cap 401. The pretreatment component 4 is placed directly in the storage device of the auxiliary agent and connected to the liquid extraction pipe 301 by the cap 401. The filter basket 402 below the cap 401 will perform preliminary filtration of the auxiliary agent when the water pump 3 is working, so as to prevent impurities and other particles from entering the water pump 3.

[0019] The diameter of the base plate 201 is smaller than the inner diameter of the storage tank 1, and the length of the cross 2 is greater than the diameter of the storage tank 1; the bottom of the cross 2 at the opposite end is fixed with a limit rod 203, and the storage tank 1 is provided with a limit groove 104 distributed in a ring array, and the limit rod 203 is inserted into the limit groove 104. The base plate 201 and the cross 2 serve as the installation carrier. When they are raised and lowered, they are inserted into the limit groove 104 through the limit rod 203 to ensure the stability during the raising and lowering process and prevent them from easily shaking or deviating.

[0020] L-shaped bent rods 202 are fixed to the top of each cross 2 at the far end. The vertical part of the bent rods 202 is fixed to the cross 2. The horizontal part of the bent rods 202 is connected to a round head 2021. The bottom end of the screw 102 is rotatably connected to the round head 2021. A handwheel 1021 is fixed to the top end of the screw 102. The bent rod 202 serves as a connector, with a round head 2021 installed in the middle. The round head 2021 is connected to the screw 102. When the screw 102 is rotated by the handwheel 1021, the height position of the cross 2 is changed.

[0021] A dispersion motor 204 is fixed at the center of the top surface of the cross 2. The output shaft of the dispersion motor 204 passes through the cross 2 and the base plate 201 and is fixed with a dispersion disk 2041. A ring array of blades 2042 is fixed on the outer periphery of the dispersion disk 2041. The dispersion disk 2041 and the blades 2042 are located inside the filter assembly 5. The dispersion motor 204 drives the dispersion disk 2041 and blades 2042 to rotate. Before the auxiliary agent output from the liquid outlet pipe 302 enters the filter assembly 5, it passes through the rotation path of the blades 2042 and is quickly processed, cut, dispersed and broken, reducing some blocky clumps.

[0022] The specific working principle of this utility model is as follows: First, the pretreatment component 4 is placed directly in the storage device of the auxiliary agent, and connected to the extraction pipe 301 via the cover 401. The water pump 3 operates, and the external auxiliary agent is extracted through the extraction pipe 301. The filter basket 402 below the cover 401 performs preliminary filtration on the passing auxiliary agent when the water pump 3 is working, preventing impurities and other particles from entering the water pump 3. Then, it is transported out through the outlet pipe 302 and input into the filter component 5 for filtration. At this time, the dispersion motor 204 operates, driving the dispersion disk 2041 and the blades 2042 to rotate. Before the auxiliary agent output from the outlet pipe 302 enters the filter component 5, it is quickly processed, cut, dispersed, and broken through the rotation path of the blades 2042. Then, the auxiliary agent enters the filter component 5, where it is further processed using... The ring frame 501 serves as the main body, supported by a large number of hook-shaped support rods 503. The filter screen 502 is installed inside the support rods 503 and below the ring frame 501, forming a cylindrical basket structure with an open top. The bottom surface is set as a cone shape to allow for a larger filtration area and facilitates the accumulation of impurities, preventing them from quickly covering the bottom surface of the filter screen 502. After filtering for a period of time, the height of the cross 2 is changed by turning the screw 102 through the handwheel 1021. During the up and down movement, the limit rod 203 is inserted into the limit groove 104 to ensure stability during the movement. When the accumulation of impurities in the filter assembly 5 can be observed, the process is stopped. The impurities can be cleaned or the work can continue. The lifting ring 5011 can be removed from the hook 205 at the bottom of the base plate 201 to remove the filter assembly 5.

[0023] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
