Technical Field
[0001] This application relates to the field of coating filtration technology, specifically to a continuous filtration and separation device for coating production. Background Technology
[0002] In the paint production process, filtration and separation to remove impurities is a crucial step in ensuring paint quality. Traditional paint filtration and separation devices often have several shortcomings. For example, some devices use intermittent filtration, requiring shutdown to clean residual impurities from the filter components after filtering a certain amount of paint. This not only reduces production efficiency but also increases production costs. Furthermore, existing filtration devices are poorly designed in terms of material conveying and circulating filtration, failing to flexibly control the material conveying speed according to actual production conditions. This can easily lead to material accumulation or over-conveying, further affecting the filtration effect.
[0003] Therefore, there is an urgent need for a filtration and separation device for paint production that can achieve continuous filtration and separation, improve filtration efficiency, and flexibly control material conveying. Summary of the Invention
[0004] To address the aforementioned technical problems, this application solves the issue that existing technologies require shutdowns for paint production and cannot achieve continuous filtration.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a continuous filtration and separation device for paint production, comprising a support frame, a separation tank fixedly mounted on the support frame, filter holes provided on the separation tank, a conveying cylinder fixedly mounted on the separation tank, a conveying spiral blade rotatably mounted on the conveying cylinder, a conveying box fixedly mounted at the end of the conveying spiral blade away from the separation tank, an inclined surface provided on the conveying box, filter holes provided on the inclined surface, an inner baffle fixedly mounted at the end of the conveying box away from the conveying spiral blade, and a rotating drum rotatably mounted on the inner baffle.
[0006] Preferably, a small fixed ring is rotatably arranged on the conveying cylinder, and multiple bottom scrapers are fixedly installed on the small fixed ring. A large fixed ring is fixedly installed at the end of the bottom scraper away from the small fixed ring. The large fixed ring is rotatably connected to the inner wall of the separation barrel. Multiple side scrapers are fixedly arranged on the large fixed ring, and an internal toothed ring is fixedly installed at the end of the side scraper away from the large fixed ring.
[0007] Preferably, a slanted retaining ring is fixedly installed on the separation barrel, the projection of the slanted retaining ring covers the inner gear ring, an outer drive shaft is rotatably arranged on the slanted retaining ring, and an inner gear is fixedly arranged at one end of the outer drive shaft near the slanted retaining ring. The inner gear meshes with the inner gear ring, and the inner gear is also covered by the slanted retaining ring.
[0008] Preferably, a motor is fixedly mounted on the support frame, and a main shaft is fixedly mounted on the output end of the motor. The main shaft is rotatably connected to the conveyor box and the separation bucket. The main shaft is fixedly connected to the conveying spiral blade. A main bevel gear is fixedly mounted on the main shaft. A secondary drive shaft is rotatably mounted on the conveyor box. A secondary bevel gear is fixedly mounted on the end of the secondary drive shaft near the main shaft. The secondary bevel gear meshes with the main bevel gear. An external gear is fixedly mounted on the end of the secondary drive shaft away from the main shaft.
[0009] Preferably, an external gear ring is fixedly installed on the rotating drum, the external gear ring meshes with an external gear, an external baffle is rotatably mounted on the rotating drum, a conveyor and two side plates are fixedly mounted on the external baffle, the side plates are fixedly mounted on the conveyor, and a side bracket is fixedly mounted on the side plate, the rotating drum is rotatably connected to the side bracket.
[0010] Preferably, a receiving plate is fixedly installed on the side support. The receiving plate is a conical funnel with an output port for discharging materials.
[0011] The technical solution provided in this application has the following advantages compared with the prior art:
[0012] 1. This application forms a circulating filter by conveying spiral blades and a conveyor box. When the material slides down the inclined surface of the conveyor box, it is filtered again. Substances that do not meet the requirements fall back into the separation tank to continue filtering until the machine stops. The entire process does not require stopping the machine midway to clean the filter holes, ensuring the continuity of filtration and greatly improving filtration efficiency.
[0013] 2. The personnel of this application can selectively control the rotation speed of the conveying spiral blades according to the amount of unfilterable material stored in the separation tank, thereby flexibly controlling the upward conveying speed of the material. This avoids conveying too much filterable material or causing too much unfilterable material to accumulate due to slow conveying speed, thus effectively ensuring the filtration effect.
[0014] 3. By setting up bottom scrapers and side scrapers, this application can automatically scrape off the material on the inner wall and bottom of the separation tank during the operation of the device, so that the material enters the conveying cylinder through the lower opening of the conveying cylinder for conveying, which effectively avoids the material from accumulating and clogging the filter holes at the lower end of the separation tank for a long time, and ensures the stability of filtration efficiency and effect.
[0015] 4. In this application, the rotating drum lifts the material and then drops it onto the conveyor by gravity for transport. At the same time, a receiving plate is set up to receive the filtered material, which realizes efficient material discharge and collection, and provides convenience for subsequent processes.

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0024] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0025] like Figures 1 to 6As shown, a continuous filtration and separation device for paint production includes a support frame 101. A separation tank 102 is fixedly mounted on the support frame 101. The separation tank 102 has filter holes. A conveying cylinder 104 is fixedly mounted on the separation tank 102. A conveying spiral blade 105 is rotatably mounted on the conveying cylinder 104. A conveying box 121 is fixedly mounted at the end of the conveying spiral blade 105 away from the separation tank 102. The conveying box 121 has an inclined surface with filter holes. The connection between the conveying box 121 and the conveying spiral blade 105 is... The conveyor box 121 is provided with an opening for inputting the material output from the conveying spiral blade 105. The conveyor box 121 is bidirectionally inclined and has output ports at both ends. After the material output from the conveying spiral blade 105 enters the conveyor box 121, it slides along the inclined surface and uses gravity. An inner baffle 122 is fixedly installed at the end of the conveyor box 121 away from the conveying spiral blade 105. A rotating drum 123 is rotatably mounted on the inner baffle 122. A guide plate is provided on the rotating drum 123 to lift the material, move it to a higher position, and then let it fall, which facilitates the conveying.
[0026] Specifically, during paint production, the material to be filtered is poured into the separator 102 through the opening at the top. The paint moves towards the center on the conical slope at the bottom of the separator 102, i.e., the location of the conveyor cylinder 104. The lower end of the conveyor cylinder 104, where it contacts the bottom of the separator 102, has multiple openings, such as... Figure 5 and Figure 6 As shown, the material enters the conveying cylinder 104 through multiple openings, and then is driven to rotate by the conveying screw 105. The screw 105 conveys the material upward inside the conveying cylinder 104. After the material reaches the upper end of the conveying screw 105, it is no longer restricted by the conveying cylinder 104 and enters the conveying box 121. Then, guided by the inclined surface on the conveying box 121, it is output from multiple directions, i.e., it slides onto the rotating drum 123, and then output to the external collection or the next processing step. When the material slides down the inclined surface of the conveying box 121, it will be filtered again through the filter holes on the inclined surface of the conveying box 121. Some of the material that meets the requirements is filtered and falls back into the separation tank 102 through the filter holes to continue filtering. This process is repeated until the machine stops, and all the material is filtered from the lower end of the separation tank 102. During the filtration process, a circulating filtration is formed by conveying spiral blades 105 and conveying box 121. The operator can selectively control the rotation speed of conveying spiral blades 105 according to the amount of unfilterable material accumulated in separation tank 102, thereby controlling the upward conveying speed of material and avoiding conveying too much filterable material or too slow conveying speed, which would cause too much unfilterable material to accumulate and affect filtration.
[0027] like Figure 5 and Figure 6As shown, a small fixed ring 108 is rotatably mounted on the conveying cylinder 104. Multiple bottom scrapers 106 are fixedly installed on the small fixed ring 108. A large fixed ring 107 is fixedly installed at the end of the bottom scraper 106 away from the small fixed ring 108. The large fixed ring 107 is rotatably connected to the inner wall of the separation barrel 102. Multiple side scrapers 109 are fixedly mounted on the large fixed ring 107. An internal toothed ring 110 is fixedly installed at the end of the side scraper 109 away from the large fixed ring 107.
[0028] Specifically, the bottom scraper 106 is attached to the bottom of the separation tank 102. The end of the bottom scraper 106 away from the small fixing ring 108 is provided with an extension that extends vertically upward. This extension is attached to the side of the inner wall of the separation tank 102. Thus, when the side scraper 109 drives the large fixing ring 107, the bottom scraper 106 and the small fixing ring 108 to rotate, the bottom scraper 106 scrapes off the material at the bottom and part of the side of the separation tank 102, while the side scraper 109 scrapes off the material on the upper part of the inner wall of the separation tank 102 that is not reached by the bottom scraper 106.
[0029] like Figure 5 and Figure 6 As shown, a slanted baffle ring 111 is fixedly installed on the separation tank 102. The projection of the slanted baffle ring 111 covers the internal gear ring 110. An external drive shaft 113 is rotatably mounted on the slanted baffle ring 111. An internal gear 112 is fixedly mounted on one end of the external drive shaft 113 near the slanted baffle ring 111. The internal gear 112 meshes with the internal gear ring 110 and is also covered by the slanted baffle ring 111. The external drive shaft 113 is also rotatably mounted on the support frame 101. When the material filtered by the inclined filter holes of the conveyor box 121 falls, it is blocked and restricted by the slanted baffle ring 111 to prevent it from dripping onto the internal gear ring 110 and the internal gear 112. Furthermore, the slanted baffle ring 111 is inclined, which can guide the dripping material back into the separation tank 102.
[0030] Specifically, a pulley is provided at the end of the outer drive shaft 113 away from the inclined stop ring 111. This pulley is connected to the main shaft 115 via a belt. When the main shaft 115 rotates, the belt drives the outer drive shaft 113 to rotate on the support frame 101 and the inclined stop ring 111. The internal gear 112 on the outer drive shaft 113, due to its meshing with the internal gear ring 110, drives the internal gear ring 110 to rotate on the inner wall of the support frame 101, thereby driving the side scraper 109, the large fixed ring 107, the bottom scraper 106, and the small fixed ring 108 to rotate. The side scraper 109, the large fixed ring 107, and the bottom scraper 106 all... The rotating ring 108 rotates on the inner wall of the separating drum 102, while the small fixed ring 108 rotates on the conveying drum 104. This causes the material to be pushed and scraped off by the side scraper 109 and the bottom scraper 106, allowing the material to enter the conveying drum 104 through the opening at the lower end of the conveying drum 104. The material is then conveyed upward by the conveying spiral blade 105, allowing the material remaining on the separating drum 102 after filtration to be removed. This prevents the material from accumulating for a long time and clogging the filter holes at the lower end of the separating drum 102, which would affect the filtration efficiency and effect. It also ensures continuous filtration without the need to stop the machine midway to clean the filter holes, thus removing the material that cannot be filtered from the separating drum 102.
[0031] like Figures 1 to 5 As shown, a motor 114 is fixedly mounted on the support frame 101, and a main shaft 115 is fixedly mounted on the output end of the motor 114. The main shaft 115 is rotatably connected to the conveying box 121 and the separation bucket 102. The main shaft 115 is fixedly connected to the conveying spiral blade 105. A main bevel gear 116 is fixedly mounted on the main shaft 115. A secondary drive shaft 118 is rotatably mounted on the conveying box 121. A secondary bevel gear 117 is fixedly mounted on the end of the secondary drive shaft 118 near the main shaft 115. The secondary bevel gear 117 meshes with the main bevel gear 116. An external gear 119 is fixedly mounted on the end of the secondary drive shaft 118 away from the main shaft 115.
[0032] Specifically, a motor 114 is installed on the support frame 101, and the power of the motor 114 drives the main shaft 115. The main shaft 115 then drives the conveying spiral blade 105 and the outer drive shaft 113 to rotate, thereby realizing the pushing and scraping of materials by the bottom scraper 106 and the conveying of materials by the conveying spiral blade 105. When the main shaft 115 rotates, the main bevel gear 116 on the main shaft 115 meshes with the secondary bevel gear 117, thereby driving the secondary bevel gear 117 and the secondary drive shaft 118 to rotate on the conveying box 121. The external gear 119 at the end of the secondary drive shaft 118 away from the main shaft 115 meshes with the external gear ring 120, thereby driving the external gear ring 120 and the rotating drum 123 to rotate on the side support 127. The inner baffle 122 blocks the end of the rotating drum 123 near the conveying box 121.
[0033] like Figure 2As shown, an external gear ring 120 is fixedly installed on the rotating drum 123. The external gear ring 120 meshes with an external gear 119. An outer baffle 125 is rotatably mounted on the rotating drum 123. A conveyor 124 and two side plates 126 are fixedly mounted on the outer baffle 125. The side plates 126 are fixedly mounted on the conveyor 124. A side bracket 127 is fixedly mounted on the side plates 126. The rotating drum 123 is rotatably connected to the side bracket 127.
[0034] Specifically, a side plate 126 and a conveyor 124 are installed on the side support 127, with one end of the conveyor 124 extending into the rotating drum 123. The rotating drum 123 rotates the material to the upper part, and then the material falls onto the conveyor belt of the conveyor 124 under the action of gravity. The conveyor 124 is controlled by external power to transport the material on the conveyor belt. During the conveyor 124's transport, the side plate 126 blocks the sides to ensure the material is transported.
[0035] like Figure 4 As shown, a receiving plate 128 is fixedly installed on the side support 127. The receiving plate 128 is a conical funnel with an output port for discharging materials.
[0036] Specifically, the material is filtered through the filter holes at the lower end of the separation tank 102, and after filtration, it falls onto the receiving plate 128, where it is received and then guided through the conical funnel of the receiving plate 128 for collection or transport to other places.
[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
