Description

Technical Field

[0001] This utility model relates to the field of coating production technology, and in particular to a filtration device for producing acrylic resin coatings. Background Technology

[0002] Acrylic resin coatings are coatings with chlorinated polyvinyl chloride resin as the main film-forming substance. During their production, solvents, pigments, curing agents, stabilizers, fillers, and other auxiliary components need to be added. Factors affecting product quality during coating production include: raw material quality, production process, production environment, and production equipment. In actual production, raw materials or equipment may introduce impurities such as particles and fibers, which will affect the quality of the coating film. In the existing technology, a filtration device with an internal filter plate is used for filtration. However, in practical applications, the following problems exist: (1) the filter plate may become clogged during filtration and needs to be disassembled and replaced, resulting in low filtration efficiency; (2) the coating is affected by temperature, and there is a problem of sedimentation and agglomeration during filtration. Therefore, in order to address the above problems, it is necessary to develop a filtration device for acrylic resin coating production. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a filtration device for the production of acrylic resin coatings, which greatly improves the filtration efficiency and prevents the coating from depositing and clumping, thus effectively ensuring the quality of the coating.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A filtration device for producing acrylic resin coatings includes a main body with an inlet at the top and an outlet at the bottom. Inside the main body is a filter plate and a rotating shaft passing through the filter plate. The rotating shaft is hollow, with one end connected to a motor and the other end connected to a heat transfer medium pipe. The rotating shaft is equipped with a first dispersing component, a second dispersing component, and a third dispersing component connected to the shaft. Below the second dispersing component is a first scraping component that adheres to the upper surface of the filter plate. Above the third dispersing component is a second scraping component that adheres to the lower surface of the filter plate.

[0006] As an improved technical solution, the first dispersion component and the third dispersion component include a hollow dispersion ring, the dispersion ring being provided with a plurality of dispersion rods connected to the dispersion ring, and the dispersion rods being provided with a plurality of dispersion blades.

[0007] As an improved technical solution, the second dispersing component includes a first dispersing disk and a second dispersing disk connected to the rotating shaft. Both the first and second dispersing disks are hollow structures. The first and second dispersing disks are connected by a hollow connecting column, and the connecting column is provided with multiple dispersing plates. The upper and lower surfaces of the first dispersing disk are respectively provided with a first dispersing block connected to the first dispersing disk, and the upper and lower surfaces of the second dispersing disk are respectively provided with a second dispersing block connected to the second dispersing disk.

[0008] As an improved technical solution, Y-shaped dispersing rods are distributed on the first dispersing disks corresponding to two adjacent first dispersing blocks and on the second dispersing disks corresponding to two adjacent second dispersing blocks.

[0009] As an improved technical solution, the first scraping component includes multiple scraping plates fixed on the rotating shaft, the bottom of the scraping plates is provided with rake teeth, and the top of the scraping plates is provided with multiple dispersing teeth.

[0010] As an improved technical solution, the second scraping component includes a conical seat disposed on the rotating shaft, and a plurality of guide rods are inclinedly disposed on the conical seat, with a scraper at the upper end of each guide rod.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are:

[0012] The filtration device for acrylic resin coating production includes a main body with an inlet and an outlet at the top and bottom, respectively. Inside the main body are filter plates and a rotating shaft passing through them. The rotating shaft is hollow, with one end connected to a motor and the other end connected to a heat transfer medium pipe. The rotating shaft is equipped with a first dispersion component, a second dispersion component, and a third dispersion component connected to it. Below the second dispersion component is a first scraper component that adheres to the upper surface of the filter plate; above the third dispersion component is a second scraper component that adheres to the lower surface of the filter plate. In actual production, the coating enters the main body through the inlet, and the heat transfer medium flows along the heat transfer medium pipe into the rotating shaft and the interiors of the first, second, and third dispersion components connected to it. After the motor starts, the rotating shaft and the first, second, and third dispersion components work together to stir the coating, ensuring uniform heating during filtration and preventing sedimentation and agglomeration. Furthermore, during filtration, the first and second scraper components scrape away the coating accumulated on the filter plate as the rotating shaft rotates, preventing clogging. The above-mentioned filtration device greatly improves filtration efficiency and effectively solves the problems of sedimentation and agglomeration and filter plate clogging caused by temperature differences during coating filtration. It also greatly improves filtration efficiency and ensures coating quality.

[0013] The first and third dispersion components include hollow dispersion rings with multiple dispersion rods connected to them, and multiple dispersion blades on the dispersion rods. The heating medium enters the dispersion rings and dispersion rods of the first and third dispersion components along the rotating shaft. As the shaft rotates, it provides the temperature required for the coating during filtration. Simultaneously, the dispersion rings, dispersion rods, and multiple dispersion blades stir and mix the coating, ensuring uniform heating, preventing the coating from depositing and clumping, and improving the dispersibility of the coating.

[0014] The second dispersion component includes a first dispersion disc and a second dispersion disc connected to a rotating shaft, both of which are hollow structures. The first and second dispersion discs are connected by a hollow connecting column, on which multiple dispersion plates are mounted. The upper and lower surfaces of the first dispersion disc each have a first dispersion block connected to it, and the upper and lower surfaces of the second dispersion disc each have a second dispersion block connected to it. The heating medium in the rotating shaft sequentially enters the interior of the first dispersion disc, the second dispersion disc, the connecting rod, the first dispersion block, and the second dispersion block to heat the coating. As the rotating shaft rotates, the first and second dispersion discs, the connecting rod, the first dispersion block, the second dispersion block, and the multiple dispersion plates achieve stirring and dispersion of the coating, ensuring uniform heating and facilitating filtration.

[0015] Y-shaped dispersing rods are distributed on the first dispersing disks corresponding to two adjacent first dispersing blocks and on the second dispersing disks corresponding to two adjacent second dispersing blocks. By setting the Y-shaped dispersing rods, the stirring and dispersing range of the coating is increased, which is more conducive to the filtration of the coating.

[0016] The first scraping component includes multiple scraper blades fixed on a rotating shaft. The scraper blades have rake teeth at the bottom and multiple dispersing teeth at the top. The rotating shaft drives the scraper blades to rotate. The dispersing teeth at the top of the scraper blades achieve the mixing and dispersion of the coating, while the rake teeth at the bottom of the scraper blades prevent the coating from accumulating on the filter plate and clogging it.

[0017] The second scraping component includes a conical seat mounted on a rotating shaft, with multiple guide rods inclined on the conical seat, each guide rod having a scraper at its upper end. The rotating shaft drives the conical seat, guide rods, and scrapers to rotate, and the scrapers scrape the coating material off the lower surface of the filter plate, with some of the coating material flowing along the guide rods to the bottom of the main body; at the same time, the guide rods also disperse and stir the coating material.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] A filtration device for acrylic resin coating production, such as Figure 1As shown, the device includes a body 1, with an inlet 10 at the top and an outlet 11 at the bottom. Inside the body 1 is a filter plate 2 and a rotating shaft 3 penetrating the filter plate 2. The rotating shaft 3 is hollow, with one end connected to a motor 4 and the other end connected to a heat medium pipe 6 via a rotary joint 5. The rotating shaft 3 is equipped with a first dispersing component 7, a second dispersing component 8, and a third dispersing component 9 connected to it. Below the second dispersing component 8 is a first scraping component 12 that adheres to the upper surface of the filter plate 2. Above the third dispersing component 9 is a second scraping component 13 that adheres to the lower surface of the filter plate 2. The first dispersing component 7 and the third dispersing component 9 include a hollow dispersing ring 70 (connected to the rotating shaft via a connecting pipe). The dispersing ring 70 has multiple dispersing rods 71 ​​connected to it, and each dispersing rod 71 has multiple dispersing blades 72. The second dispersing component 8 includes a first dispersing disk 80 and a second dispersing disk 81 connected to the rotating shaft 2. Both the first dispersing disk 80 and the second dispersing disk 81 are hollow structures (connected to the rotating shaft via connecting pipes). The first dispersing disk 80 and the second dispersing disk 81 are connected by a hollow connecting column 82, on which multiple dispersing plates 83 are provided. The upper and lower surfaces of the first dispersing disk 80 are respectively provided with first dispersing blocks 800 connected to the first dispersing disk 80, and the upper and lower surfaces of the second dispersing disk 81 are respectively provided with second dispersing blocks 810 connected to the second dispersing disk 81. The first scraping component 12 includes multiple scraping plates 120 fixed on the rotating shaft 2. The bottom of the scraping plate 120 is provided with rake teeth 1200, and the top of the scraping plate 120 is provided with multiple dispersing teeth 121. The second scraping component 13 includes a conical seat 130 disposed on the rotating shaft 2. Multiple guide rods 131 are inclinedly disposed on the conical seat 130, and a scraper 132 is provided at the upper end of each guide rod 131.

[0022] In actual production, the produced coating enters the main body through the feed inlet. The heat medium enters the rotating shaft along the heat medium pipe, and then enters the dispersion rings and dispersion rods of the first and third dispersion components, as well as the first dispersion disc, second dispersion disc, connecting rod, first dispersion block, and second dispersion block of the second dispersion component. After the motor starts, the rotating shaft, the first dispersion component (dispersion ring and dispersion rod), the second dispersion component (first dispersion disc, second dispersion disc, connecting rod, first dispersion block, and second dispersion block), and the third dispersion component (dispersion ring and dispersion rod) work together to stir the coating, ensuring that the coating is heated evenly during filtration and preventing sedimentation and agglomeration. In addition, during filtration, the rotating shaft drives the scraper of the first scraper component to rotate. The dispersion teeth on the top of the scraper plate achieve stirring and dispersion of the coating, and the rake teeth at the bottom of the scraper plate prevent the coating from accumulating on the filter plate and clogging it. The first and second scraper components scrape off the coating accumulated on the filter plate as the rotating shaft rotates, preventing clogging on the upper surface of the filter plate. Simultaneously, the rotating shaft drives the conical seat, guide rod, and scraper of the second scraping component to rotate. The scraper scrapes down the coating on the lower surface of the filter plate, and some of the coating flows along the guide rod to the bottom of the main body. The guide rod also disperses and stirs the coating. This filtration device significantly improves filtration efficiency, effectively solving the problems of coating deposition and agglomeration caused by temperature differences and filter plate clogging during filtration, thus greatly improving filtration efficiency while ensuring coating quality. After filtration, coating meeting the standards is discharged from the outlet for repackaging.

[0023] Y-shaped dispersing rods 84 are distributed on the first dispersing disks 80 corresponding to two adjacent first dispersing blocks 800 and on the second dispersing disks 81 corresponding to two adjacent second dispersing blocks 810. By setting the Y-shaped dispersing rods, the stirring and dispersing range of the coating is increased, which is more conducive to the filtration of the coating.

[0024] The first dispersing component 7 is equipped with a spray pipe 14 above it, and a discharge port 15 is provided on the body corresponding to one side of the filter plate (the discharge port is equipped with a sealing cover, which is hinged to the discharge port). After filtration, the coating material that meets the standard is discharged from the outlet; the washing liquid enters the interior of the spray pipe through a conveying pump, and the sprayed washing liquid washes the filter plate, while the large particles of impurities trapped on the filter plate are discharged from the discharge port on one side.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
