Description

Technical Field

[0001] The invention belongs to the technical field of filtering devices, and in particular relates to an electrophoresis waste liquid filtering device. Background Art

[0002] Electrophoresis is the process by which charged particles migrate toward an electrode with opposite electrical properties under the influence of an electric field. Electrophoresis is a technique that uses the different speeds of charged particles in an electric field to achieve separation. Electrophoretic coating is a special coating formation method developed in the past 30 years. Electrophoretic paint films offer the advantages of a full, uniform, smooth, and even coating. Their hardness, adhesion, corrosion resistance, impact resistance, and permeability are significantly superior to other coating processes. It is also water-soluble, non-toxic, and easily automated, making it widely used in the automotive, electronics, building materials, hardware, and other industries. Consequently, electrophoretic wastewater is generated and has become a widely used type of industrial wastewater, characterized by a wide variety of pollutants and a complex composition. The existing method for treating electrophoresis waste liquid mainly uses various filtering devices to directly filter the waste liquid. Since the electrophoresis waste liquid contains various substances such as water-soluble resins, pigments, fillers, etc., the method of direct filtration using gravity is less efficient. An existing method is to use centrifugal filtration equipment to centrifuge it. However, after the existing centrifugal filtration equipment is used, a large amount of intercepted impurities remain in the centrifugal cylinder, which needs to be manually cleaned before it can be filtered again. Summary of the Invention

[0003] The purpose of the present invention is to provide an electrophoresis waste liquid filtering device, which solves the problem that after the existing electrophoresis waste liquid filtering device is used, a large amount of intercepted impurities remain in the centrifugal cylinder of the existing centrifugal filtering equipment, which needs to be manually cleaned before it can be filtered again.

[0004] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] An electrophoresis waste liquid filtration device comprises a first filtration module and a second filtration module, wherein the first filtration module and the second filtration module are arranged correspondingly, and the second filtration module is used to re-filter the waste liquid filtered by the first filtration module;

[0006] The first filtration module includes a funnel, a centrifugal cylinder, a driving mechanism, and a filter assembly. The funnel is provided with a centrifugal cylinder, the centrifugal cylinder is connected to the driving mechanism, and a plurality of filter assemblies are fixed to the inner wall of the centrifugal cylinder along the circumference. The driving mechanism is used to drive the centrifugal cylinder to rotate so that the waste liquid in the centrifugal cylinder enters the filter assembly under the action of centrifugal force.

[0007] The filter assembly includes a mounting box, a sealing cylinder, a filter cylinder, a scraper mechanism, and a rotating mechanism. The mounting box is in the shape of an elongated strip, and a mounting opening is provided on one side of the mounting box. A sealing cylinder is rotatably installed in the mounting opening. The sealing cylinder is arranged parallel to the mounting box, and a filter cylinder is coaxially fixed in the sealing cylinder. A water inlet is provided through the side of the sealing cylinder, and a plurality of filter holes are provided on the inner wall of the filter cylinder corresponding to the water inlet. A plurality of scraper mechanisms are arranged around the sealing cylinder in the mounting box.

[0008] The rotating mechanism is used to drive the sealing cylinder and the filter cylinder to rotate by utilizing centrifugal force, so that the scraper mechanism can scrape off impurities on the surface of the filter cylinder;

[0009] The rotating mechanism includes a rotating shaft, a fixed plate, a crank-connecting rod structure, a telescopic rod, and a telescopic structure. The rotating shaft is coaxially fixedly connected to the filter cylinder and the sealing cylinder. The telescopic rod is penetrated by the fixed plate. The telescopic rod is telescopically mounted on the fixed plate through the telescopic mechanism. The fixed plate is connected to the mounting box. The telescopic rod is arranged radially parallel to the centrifugal cylinder. One end of the telescopic rod is transmission-connected to the rotating shaft through the crank-connecting rod structure, so that the rotating shaft can be synchronously driven to rotate by the crank-connecting rod structure when the telescopic rod performs reciprocating telescopic motion.

[0010] Furthermore, a sealing strip tightly fitted therewith is provided on the mounting openings on both sides of the sealing cylinder, and a curved surface adapted to the sealing cylinder is provided on the sealing strip on the side facing the sealing cylinder.

[0011] Furthermore, the scraper mechanism includes a scraper, a scraper seat, and an elastic element. One end of the scraper seat is connected to the mounting box, and the other end of the scraper seat is provided with a mounting groove. The scraper can be telescopically mounted in the mounting groove through the elastic element.

[0012] Furthermore, the scraper is a rubber scraper.

[0013] Furthermore, a counterweight is fixedly mounted on one end of the telescopic rod away from the rotating shaft.

[0014] Furthermore, the second filter module includes a bottom box, a filter screen, a reciprocating motion mechanism, and a transmission mechanism. The filter screen is arranged in the bottom box. The reciprocating motion mechanism is used to drive the filter screen to perform reciprocating motion in the horizontal direction. The reciprocating motion mechanism is connected to the drive mechanism through the transmission mechanism.

[0015] The present invention has the following beneficial effects:

[0016] By setting up two filter modules, after filtering using the centrifugal force generated by the first filter module, the water is filtered again using gravity in the filter screen of the second filter module, and the filtering effect is better and faster; and the filter assembly set in the first filter module can use the centrifugal force generated by the rotating centrifuge barrel to automatically remove intercepted impurities, so that the operator does not need to clean the first filter module frequently.

[0027] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] See also Figure 1-6 The present invention is a pull-plate type weighing sensor, comprising a first filter module and a second filter module, wherein the first filter module and the second filter module are correspondingly arranged, and the second filter module is used to filter the waste liquid filtered by the first filter module again;

[0029] The first filter module includes a funnel 1, a centrifugal drum 3, a driving mechanism, and a filter assembly 9. The funnel 1 is provided with a centrifugal drum 3, which is connected to the driving mechanism. Several filter assemblies 9 are fixed circumferentially to the inner wall of the centrifugal drum 3. The driving mechanism is used to drive the centrifugal drum 3 to rotate so that the waste liquid in the centrifugal drum 3 enters the filter assembly 9 under the action of centrifugal force. The driving mechanism includes a driving motor 4 and a driving shaft 2. The driving shaft 2 is coaxially fixedly connected to the centrifugal drum 3. The driving shaft 2 is connected to the driving motor 4, and the driving motor 4 is used to drive the shaft 2 to rotate. The second filter module includes a bottom box 5, a filter screen 6, a reciprocating motion mechanism 8, and a transmission mechanism 7. The bottom box 5 is provided with a filter screen 6. The reciprocating motion mechanism 8 is used to drive the filter screen 6 to reciprocate in the horizontal direction. The reciprocating motion mechanism 8 is connected to the driving mechanism in the first filter module through the transmission mechanism 7. The reciprocating motion mechanism 8 includes a guide rod, a sliding sleeve, a pull rod, a fixed disk, a rack, and an incomplete gear. A guide rod is arranged on each side of the filter screen 6, and the two guide rods are arranged parallel to each other. A sliding sleeve is sleeved on each guide rod, and the sliding sleeves are fixedly connected to the filter screen 6. The pull rod is arranged on the bottom box 5, and the pull rod is arranged parallel to the guide rod. The inner end of the pull rod is connected to the filter screen 6, and a fixed disk is fixed to the outer end of the pull rod. A spring is sleeved on the pull rod between the fixed disk and the bottom box 5, and the rack is arranged parallel to the pull rod. An incomplete gear meshing with it is arranged on one side of the rack; the transmission mechanism 7 includes a transmission shaft and a sprocket structure. The transmission shaft is coaxially fixedly connected to the incomplete gear, and the transmission shaft is arranged parallel to the drive shaft 2. The transmission shaft is connected to the drive shaft 2 through a sprocket structure.

[0030] As attached Figure 2-3As shown, the filter assembly 9 is installed on the centrifugal cylinder 3 in an embedded installation manner, so that the sealing cylinder 902, the filter cylinder 904, and the bottom end of the installation box 901 can be partially exposed outside the centrifugal cylinder 3, thereby facilitating the discharge of liquid and impurities. The filter assembly 9 includes the installation box 901, the sealing cylinder 902, the filter cylinder 904, the scraper mechanism 905, and the rotating mechanism. The installation box 901 is in the shape of an elongated strip, and a mounting opening is provided on one side of the installation box 901. The sealing cylinder 902 is rotatably installed in the mounting opening. The sealing cylinder 902 is arranged parallel to the installation box 901. The filter cylinder 904 is coaxially fixed in the sealing cylinder 902. A water inlet is provided through the side of the sealing cylinder 902. A plurality of filter holes are provided on the inner wall of the filter cylinder 904 corresponding to the water inlet. A plurality of scraper mechanisms 905 are provided in the installation box 901 around the sealing cylinder 902.

[0031] The rotating mechanism is used to utilize centrifugal force to drive the sealing cylinder 902 and the filter cylinder 904 to rotate, so that the scraper mechanism 905 can scrape impurities off the surface of the filter cylinder 904. Because the outer diameter of the sealing cylinder 902 is larger than that of the filter cylinder 904, impurities on the surface of the filter cylinder 904 will not be scraped off by the inner wall of the mounting opening of the mounting box 901 and fall into the centrifugal cylinder 3 during the rotation process of the filter cylinder 904. Only when the filter cylinder 904 rotates into the mounting box 901 can the scraper mechanism 905 scrape impurities off the surface of the filter cylinder 904, so that the scraped impurities fall outside the centrifugal cylinder 3.

[0032] A sealing strip 903 is provided on each side of the mounting opening of the sealing cylinder 902, which fits tightly therewith. The sealing strip 903 has a curved surface on the side facing the sealing cylinder 902 that matches the sealing cylinder 902. If the gap between the sealing cylinder 902 and the mounting box 901 is too large, some waste liquid will enter the mounting box 901 directly through the gap without being filtered and be discharged. Therefore, two sealing strips 903 are provided. The curved surface of the sealing strip 903 can increase the contact area between the sealing strip 903 and the sealing cylinder 902, thereby achieving a better sealing effect.

[0033] The scraper mechanism 905 includes a scraper, a scraper seat, and an elastic element. One end of the scraper seat is connected to the installation box 901, and the other end of the scraper seat is provided with a mounting groove. The scraper can be retractably installed in the mounting groove through the elastic element.

[0034] The scraper is a rubber scraper. The retractable scraper is provided because the outer diameter of the sealing cylinder 902 is larger than that of the filter cylinder 904. Therefore, when the filter cylinder 904 rotates to the side of the installation box 901, the scraper is pushed outward by the elastic element to a certain distance, so that the scraper can still contact the surface of the filter cylinder 904, thereby achieving the scraping operation.

[0035] When the present invention is in use, in the initial state, as shown in the attached Figure 6As shown, a filter hole is opened on the filter cartridge 904 in each filter assembly 9 and one side is placed in the installation box 901. When the driving mechanism in the first filter module is started, the driving mechanism drives the centrifugal cylinder 3 to rotate. At this time, the centrifugal force generated by the rotation of the centrifugal cylinder 3 will cause the telescopic rod 909 on the filter assembly 9 to move outward. The telescopic rod 909 synchronously drives the rotating shaft 907 to rotate through the crank connecting rod structure 908. The rotating shaft 907 drives the sealing cylinder 902 and the filter cartridge 904 to rotate. As shown in the attached figure Figure 5 As shown, at this time, the side of the filter cartridge 904 with the filter holes will be placed outside the installation box 901; then the waste liquid is poured into the rotating cylinder, and under the action of centrifugal force, the waste liquid quickly passes through the multiple filter mechanisms arranged on the inner wall of the rotating cylinder, and the filter assembly 9 of the filter mechanism intercepts a large amount of impurities on the outer surface of the filter cartridge 904; when the waste liquid is filtered, the driving mechanism is stopped, the centrifugal cylinder 3 stops rotating, the telescopic rod 909 automatically resets, and the filter cartridge 904 also resets to its initial state. During this process, the scraper mechanism 905 will scrape off the impurities intercepted on the surface of the filter cartridge 904, so that the operator does not need to frequently clean the first filter module.

[0036] A specific application of this embodiment is as follows: the rotating mechanism includes a rotating shaft 907, a fixed plate 9010, a crank-connecting rod structure 908, a telescopic rod 909, and a telescopic structure. The rotating shaft 907 is coaxially fixedly connected to the filter cartridge 904 and the sealing cartridge 902. The fixed plate 9010 is provided with a telescopic rod 909, which is telescopically mounted on the fixed plate 9010 via the telescopic mechanism. The fixed plate 9010 is connected to the mounting box 901. The telescopic rod 909 is arranged radially parallel to the centrifugal cylinder 3. One end of the telescopic rod 909 is transmission-connected to the rotating shaft 907 via the crank-connecting rod structure 908, so that when the telescopic rod 909 performs reciprocating telescopic motion, the crank-connecting rod structure 908 can synchronously drive the rotating shaft 907 to rotate. A counterweight is fixedly mounted on the end of the telescopic rod 909 away from the rotating shaft 907. When the rotating mechanism is in use, it is driven by the centrifugal force generated by the rotation of the centrifugal cylinder 3, so a counterweight is provided to make the telescopic rod 909 more easily telescopic under the action of the centrifugal force.
