Description

Technical Field

[0001] This utility model relates to the field of paint production technology, and in particular to a feeding device for exterior wall paint production. Background Technology

[0002] In the field of architectural coatings production, exterior wall paints, due to their need for weather resistance and stain resistance, require stringent standards for the accuracy of raw material proportioning and the stability of material feeding during production. A feeding device for exterior wall paint production, as a key piece of equipment connecting raw material storage and mixing, is responsible for accurately conveying solid powder and liquid raw materials to the mixing stage according to process requirements. Its performance directly affects the quality stability and production efficiency of exterior wall paint products, and is an important guarantee for achieving large-scale, continuous production of exterior wall paints.

[0003] In existing technologies, the feeding device for exterior wall paint production usually adopts a split design. Solid powder feeding mostly relies on the weight of the silo for feeding, while liquid raw materials are drawn by a pump and discharged directly through a pipeline. The technical principle is mainly to use gravity to make the raw materials flow, and the feeding start and stop are controlled by a manual valve. Some devices will install a vibrator at the bottom of the powder silo in an attempt to reduce powder agglomeration through vibration. The liquid pipeline is only equipped with a regular on / off valve to control the flow.

[0004] However, existing technologies often encounter problems in the solid powder feeding process: powder tends to stick and remain on the inner wall of the silo, and clumps of powder can easily cause blockages in the conveying channel, leading to interruptions in feeding and requiring frequent shutdowns for cleaning. This severely affects the continuity of feeding, increases labor costs and production time, and makes it difficult to meet the needs of high-efficiency production. Therefore, a feeding device for exterior wall paint production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a feeding device for exterior wall paint production, which aims to improve the problem of clogging caused by existing powder residue, resulting in interruption of feeding.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feeding device for producing exterior wall paint includes a base plate, a material collection hopper fixedly connected to the right side of the base plate, a material storage component above the material collection hopper, and a liquid storage component on the side of the material storage component.

[0008] The storage assembly includes a storage tank, a fixing component at the bottom of the storage tank, the fixing component being fixedly connected to the top of the base plate, a drive motor being fixedly connected to the top of the storage tank, a drive shaft being fixedly connected to the output end of the drive motor, a feed pipe being provided on the side of the drive motor, the bottom of the feed pipe being fixedly connected to the top of the storage tank, the drive shaft being located inside the storage tank, a connecting block being fixedly connected to the outer wall of the drive shaft, multiple scrapers being fixedly connected to the outer wall of the connecting block, the scrapers being distributed in a circumferential pattern, a screw conveyor being fixedly connected to the bottom of the drive shaft, a discharge pipe being fixedly connected to the center of the bottom of the storage tank, and the bottom outer wall of the screw conveyor being slidably connected to the inner wall of the discharge pipe.

The bottoms of the multiple support columns are fixedly connected to the top of the base plate.

[0011] As a further description of the above technical solution:

[0012] The liquid storage assembly includes a liquid storage tank, and an inlet pipe is fixedly connected to the top of the liquid storage tank.

[0013] As a further description of the above technical solution:

[0014] A control valve is fixedly connected to the bottom of the outer wall of the storage tank, and an outlet pipe is fixedly connected to the output end of the control valve.

[0015] As a further description of the above technical solution:

[0016] A dustproof box is fixedly connected to the outer wall of one end of the liquid outlet pipe, and the bottom of the dustproof box is aligned with the top of the collection hopper.

[0017] As a further description of the above technical solution:

[0018] One end of the liquid outlet pipe is slidably connected to a sealing cap, which is located inside the dustproof box. Symmetrical connecting arms are fixedly connected to the outer wall of the sealing cap.

[0019] As a further description of the above technical solution:

[0020] A connecting shaft is provided above the connecting arm, and the tops of both connecting arms are fixedly connected to the outer wall of the connecting shaft. Both ends of the connecting shaft are rotatably connected to the inner wall of the dustproof box.

[0021] As a further description of the above technical solution:

This solves the problem of raw material contamination caused by impurities easily entering the outlet pipe when it is idle, and improves the cleanliness of liquid feeding.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a feeding device for exterior wall paint production, comprising a base plate 1 made of Q235B steel plate. The base plate 1 serves as the basic load-bearing component of the entire device, supporting the collecting hopper 4, the material storage assembly, and the liquid storage assembly, ensuring the stability of the device during operation. The collecting hopper 4 is fixedly connected to the right side of the base plate 1 by welding. The collecting hopper 4 is made of 304 stainless steel plate, bent and welded, and is funnel-shaped with a polished inner wall. It is used to collect raw materials fed from the material storage assembly and the liquid storage assembly, and centrally transport them to the subsequent mixing equipment.

[0035] The storage assembly above the collecting hopper 4 is used to store solid powdery raw materials. It consists mainly of a storage tank 5, which is welded from 304 stainless steel plate and is cylindrical. A sealing cap is welded to the top to prevent the raw materials from getting damp or contaminating with impurities. A fixing assembly at the bottom of the storage tank 5 is used to stably fix it above the base plate 1. The support plate 2 of the fixing assembly is made of Q345B steel plate. The bottom of the storage tank 5 is bolted to the top of the support plate 2. The support plate 2 is located directly above the collecting hopper 4 to ensure accurate material feeding into the collecting hopper 4. Support columns 3 are welded to the four corners of the support plate 2. The bottom of the support columns 3 is welded to the top of the base plate 1 to support the support plate 2 and the storage tank 5, ensuring... The storage tank 5 is installed at a certain height. The top of the storage tank 5 is fixedly connected to the drive motor 10 by bolts. The drive motor 10 is a three-phase asynchronous motor, which is used to provide rotational power to the transmission shaft 11. The drive motor 10 is existing technology and will not be described in detail in this article. The output end of the drive motor 10 is fixedly connected to the transmission shaft 11 by a coupling. The transmission shaft 11 is made of 45 steel and has a chrome-plated surface. It is located inside the storage tank 5 and is used to transmit the power of the drive motor 10 to drive the scraper 13 and the screw conveyor 14 to rotate. The feed pipe 6 on the side of the drive motor 10 is made of seamless steel pipe and is welded to the top of the storage tank 5 at the bottom. It is connected to the inside of the storage tank 5 and is used to inject solid powder raw materials into the storage tank 5. A connecting block 12 is welded to the outer wall of the drive shaft 11. The connecting block 12 is made of 45 steel and is used to connect the drive shaft 11 and the scraper 13. Multiple scrapers 13 are welded to the outer wall of the connecting block 12 in a circular pattern. The scrapers 13 are made of 304 stainless steel and the gap between them and the inner wall of the storage tank 5 is controlled at 1-2 mm. They are used to scrape off the powder adhering to the inner wall of the storage tank 5 when rotating, so as to avoid material waste and blockage. The bottom of the drive shaft 11 is connected to the screw conveyor 14 by a key. The screw conveyor 14 is made of 304 stainless steel and the diameter of the screw blades is adapted to the bottom of the storage tank 5. It is used to convey the powder in the storage tank 5 downward. The discharge pipe 7 is welded to the center of the bottom of the storage tank 5. The discharge pipe 7 is made of 304 stainless steel and is connected to the inside of the storage tank 5. The bottom outer wall of the screw conveyor 14 and the inner wall of the discharge pipe 7 form a clearance fit to ensure that the powder falls accurately into the collection hopper 4 through the discharge pipe 7.

[0036] Reference Figure 4 and Figure 5The liquid storage assembly centers on a storage tank 9, which is welded from 304 stainless steel plate and is cylindrical in shape with a sealed cap welded to the top. It stores liquid raw materials required for exterior wall paint production, such as emulsions and solvents. The material has excellent corrosion resistance, preventing chemical reactions between the liquid raw materials and the tank. An inlet pipe 8, also made of 304 stainless steel, is welded to the top of the storage tank 9 and connects to the interior of the tank. This inlet pipe injects liquid raw materials into the storage tank 9. Its port can be connected to a delivery pump or other liquid supply equipment to ensure smooth injection of the liquid raw materials. A control valve 15, a stainless steel ball valve, is fixedly connected to the bottom of the outer wall of the storage tank 9 via a flange. The control valve 15 has excellent sealing and corrosion resistance. The control valve 15 is used to control the output and cut-off of liquid raw materials inside the storage tank 9. The liquid flow rate can be adjusted by rotating the valve stem to meet the needs of different production conditions. The control valve 15 is existing technology and will not be described in detail here. The output end of the control valve 15 is fixedly connected to the outlet pipe 16 via a flange. The outlet pipe 16 is made of 304 stainless steel and is used to transport the liquid raw materials output by the control valve 15 to the collection hopper 4. Its inner wall is polished to reduce liquid residue in the pipe. One end of the outlet pipe 16 is fixedly connected to the outer wall of a dustproof box 17 by bolts. The dustproof box 17 is made of 304 stainless steel plate and has a rectangular structure with an open bottom aligned with the top of the collection hopper 4. It is used to protect the outlet end of the outlet pipe 16 from external dust. Impurities entering the outlet pipe 16 cause contamination. A sealing cap 23 is slidably connected to one end of the outlet pipe 16. The sealing cap 23 is made of food-grade silicone, is disc-shaped, and matches the size of the outlet end of the outlet pipe 16. Located inside the dustproof box 17, it seals the outlet end of the outlet pipe 16 after liquid delivery to prevent contaminants from entering. Symmetrical connecting arms 22 are bolted to the outer wall of the sealing cap 23. The connecting arms 22 are made of Q235B steel plate and are used to connect the sealing cap 23 and the connecting shaft 21, transmitting the rotational movement of the connecting shaft 21. The connecting shaft 21, located above the connecting arms 22, is made of 45# steel and its two ends are rotatably connected to bearing seats pre-set on the inner wall of the dustproof box 17 via bearings. The connecting shaft 21 is used to drive the connecting arm 22 and the sealing cover 23 to rotate, thereby opening and closing the outlet end of the liquid outlet pipe 16. A rocker arm 20 is fixedly connected to one side of the connecting shaft 21 by a key. The rocker arm 20 is made of Q235B steel plate and is used to convert the thrust of the electric actuator 19 into the rotational force of the connecting shaft 21. A fixing block 18 is fixedly connected to one side of the inner wall of the dust box 17 by welding. The fixing block 18 is used to fix the electric actuator 19. The electric actuator 19 is fixedly connected to the inside of the fixing block 18 by bolts. The electric actuator 19 is an electric actuator used to provide power for the rotation of the rocker arm 20. The electric actuator 19 is existing technology and will not be described in detail in this article. Its output end is rotatably connected to one end of the rocker arm 20 by a pin to ensure that the rocker arm 20 can rotate flexibly.

[0037] Working principle: When using this external wall paint production feeding device, solid powder raw materials are first injected into the storage tank 5 through the feed pipe 6, and liquid raw materials are injected into the storage tank 9 through the liquid inlet pipe 8. When processing and mixing are required, the drive motor 10 at the top of the storage tank 5 drives the transmission shaft 11 to rotate. The rotation of the transmission shaft 11 causes the connecting block 12 to drive the scraper 13 to rotate. The scraper 13 slides on the inner wall of the storage tank 5 to scrape off the powder adhering to the inner wall. On the other hand, it also drives the screw conveyor 14 to rotate. When the screw blades of the screw conveyor 14 rotate, they can generate axial thrust on the powder. Even clumps of powder can be forcibly pushed into the collection hopper 4, thereby achieving stable feeding and avoiding blockage.

[0038] After the powder is conveyed, the control valve 15 extracts the liquid material from the storage tank 9 and discharges it into the collection hopper 4 through the outlet pipe 16. At this time, the output end of the electric actuator 19 pulls one end of the rocker arm 20 to move. The movement of one end of the rocker arm 20 causes the connection point between its other end and the connecting shaft 21 to rotate, which in turn causes the connecting shaft 21 to rotate the connecting arm 22 at its bottom. The rotation of the connecting arm 22 causes the sealing cover 23 to rotate as well, thereby opening the outlet end of the outlet pipe 16. After the liquid material is conveyed, the output end of the electric actuator 19 pushes the rocker arm 20 to move in the opposite direction, thereby causing the sealing cover 23 to return to its original position and seal the outlet end of the outlet pipe 16, thus preventing the outlet pipe 16 from being contaminated.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
