Description

Technical Field

[0001] This utility model mainly relates to the field of insulating coating production technology, specifically to a raw material filtration device for insulating coating production. Background Technology

[0002] In the production of insulating coatings, the purity of raw materials plays a crucial role in the performance of the final product. Traditional raw material filtration methods have many limitations. For example, some simple filter devices rely solely on fixed filter screens, which are easily clogged by impurities. Once clogged, the filtration efficiency drops sharply, requiring frequent shutdowns for manual cleaning. This not only increases labor costs but also severely impacts production efficiency. Moreover, it is difficult to ensure that the filter screen is thoroughly cleaned during the cleaning process, and residual impurities may affect subsequent filtration effects, leading to unstable product quality.

[0003] Furthermore, for insulating coating raw materials with complex compositions, containing various additives and solid particles of different sizes, traditional filtration devices lack an effective stirring mechanism. The raw materials are prone to stratification and sedimentation within the filtration container, preventing some materials from fully contacting the filter screen for filtration. This results in incomplete filtration, incomplete removal of impurities, and negatively impacts key quality indicators of the insulating coating, such as insulation performance and adhesion. Utility Model Content

[0004] 1. The technical problem to be solved by the utility model:

[0005] This invention provides a raw material filtration device for the production of insulating coatings, in order to solve the technical problems existing in the background art.

[0006] 2. Technical Solution:

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: a raw material filtration device for the production of insulating coatings, comprising a circular tank, an inlet on the tank, a discharge pipe at the bottom, a drive motor at the top, the drive motor being fixedly connected to a rotating shaft, the rotating shaft being rotatably mounted at the center of the tank, a filter cylinder being concentrically arranged inside the tank, filter holes being provided on the side wall and bottom of the filter cylinder, a discharge space being formed between the filter cylinder and the tank, and a cleaning component and a stirring component being provided on the rotating shaft, the cleaning component being used to clean the filter holes, and the stirring component being used to stir the raw materials.

[0008] Preferably, the bottom of the tank is provided with several support feet, and the top end is provided with a top cover. The top cover is provided with a motor mounting bracket for installing the drive motor, and the discharge pipe is provided with a solenoid valve.

[0009] Preferably, the stirring assembly comprises a mounting ring fixed on the rotating shaft, and a plurality of stirring rods are fixedly mounted on the mounting ring at equal distances.

[0010] Preferably, the cleaning assembly comprises a connecting cylinder fixed on the side wall of the rotating shaft, and an installation block is arranged at the other end of the connecting cylinder.

[0011] Preferably, a limiting block is fixedly mounted on the connecting cylinder, an installation block is arranged on the connecting cylinder, a movable column is fixedly mounted on one end of the installation block close to the connecting cylinder, the movable column is slidingly installed in the connecting cylinder, a spring is sleeved and mounted on the connecting cylinder, one end of the spring is fixed on the limiting block, and the other end of the spring is fixed on the installation block.

[0012] 3. Beneficial effects:

[0013] Compared with the prior art, the technical scheme has the following beneficial effects:

[0014] The filter hole of the filter cylinder can effectively intercept impurity particles in the raw material, and the purity of the insulating coating raw material is ensured. By reasonably setting the size of the filter hole, impurities of different particle sizes can be removed, and the requirements of the insulating coating production on the purity of the raw material can be met. When producing high-precision insulating coating, removing the tiny impurities can improve the insulation performance and stability of the coating. The continuous cleaning of the filter hole by the cleaning assembly prevents the filter hole from being blocked, and maintains the high filtering performance of the filtering device. Even if the filter hole is blocked by impurities during the filtering process, the cleaning brush can clean it in time, so that the raw material can continuously and stably pass through the filter hole into the discharging space, and the filtering efficiency is prevented from being reduced or interrupted due to the blockage of the filter hole. The cooperation of the cleaning assembly and the filter cylinder ensures that the filtering device can work continuously and efficiently. The production efficiency is improved, and the production cost is reduced.

[0015] The stirring of the raw material by the stirring assembly makes the raw material uniformly distributed in the filter cylinder, and promotes the uniformity of the filtering process. For the insulating coating raw material with complex composition and easy stratification, stirring can prevent stratification of the raw material, and ensure that each part of the raw material can be fully filtered, thereby improving the filtering quality. For the insulating coating raw material containing various additives and solid particles of different particle sizes, stirring can uniformly disperse the additives in the raw material, and simultaneously make the solid particles uniformly contact with the filter hole for filtering. Thus, the impurities in the raw material can be removed accurately, and the purity of the produced insulating coating is higher and the performance is more stable. The reduction of impurities can reduce the risk of electric conduction of the insulating coating during use, improve the insulation performance, and prolong the service life of the insulating coating.

[0030] A plurality of supporting legs 11 are arranged at the bottom of the tank body 1, a top cover 12 is arranged at the upper end of the tank body 1, a motor mounting seat for mounting the driving motor 2 is arranged on the top cover 12, and an electromagnetic valve 15 is arranged on the discharge pipe 14.

[0031] The stirring assembly 6 comprises a mounting ring 61 fixed on the rotating shaft 3, and a plurality of stirring rods 62 are fixedly installed on the mounting ring 61 at equal distances.

[0032] The cleaning assembly 5 includes a connecting cylinder 51 fixed on the side wall of the rotating shaft 3, and the other end of the connecting cylinder 51 is provided with a mounting block 52, and the mounting block 52 is provided with a cleaning brush 53. The connecting cylinder 51 is fixedly installed with a limiting block 54, the mounting block 52 is provided with a connecting block 55, the connecting block 55 is fixedly installed with a movable column 56 close to one end of the connecting cylinder 51, the movable column 56 is slidingly installed in the connecting cylinder 51, the connecting cylinder 51 is sleeved and installed with a spring 57, one end of the spring 57 is fixed on the limiting block 54, and the other end is fixed on the connecting block 55.

[0033] Working principle: The insulating coating raw material enters the filter cylinder 4 in the tank body through the feed port 13 on the tank body 1. At this time, the driving motor 2 is in a stopped state, the electromagnetic valve 15 closes the discharge pipe 14, and the raw material starts to accumulate in the filter cylinder 4.

[0034] Start the driving motor 2, and the driving motor 2 drives the rotating shaft 3 to start rotating. The stirring assembly 6 on the rotating shaft 3 rotates, and the stirring rod 62 stirs the raw material in the filter cylinder 4. The stirring effect is to make the raw material uniformly distributed, prevent the raw material from depositing or locally accumulating in the filter cylinder 4, and ensure that all the raw material can be fully contacted with the filter holes 41 of the filter cylinder 4 for filtering. For example, for some insulating coating raw materials containing solid particles and liquid components, stirring can uniformly disperse the solid particles in the liquid, avoiding large particle agglomeration to block the filter holes 41.

[0035] With the stirring, the liquid part and smaller particle impurities in the raw material start to enter the discharge space 7 through the filter holes 41 under the action of the pressure difference. The size of the filter holes 41 is determined according to the particle size of the impurities to be filtered, for example, for removing impurities with a particle size greater than 100 microns, the diameter of the filter holes 41 can be set to 80-100 microns.

[0036] While the rotating shaft 3 rotates, the cleaning assembly 5 also works. The connecting cylinder 51 rotates with the rotating shaft 3, and drives the cleaning brush 53 on the mounting block 52 to clean the filter holes 41 of the filter cylinder 4. When the cleaning brush 53 encounters the blockage on the filter holes 41, due to the action of the spring 57, the movable column 56 slides in the connecting cylinder 51, and the mounting block 52 can move flexibly within a certain range, so that the cleaning brush 53 can better fit the surface of the filter holes 41, effectively removing the blockage. For example, if some sticky impurities adhere to the filter holes 41, the cleaning brush 53 can increase the cleaning force of the blockage with the assistance of the spring 57, to ensure the smoothness of the filter holes 41.

[0037] The filtered raw material enters the discharge space 7, and when it is necessary to discharge the filtered raw material, the electromagnetic valve 15 is opened, and the raw material flows out of the tank body 1 through the discharge pipe 14 and enters the subsequent production process or storage container.

[0038] When the filtering work is completed or the set filtering time, raw material processing amount and other conditions are reached, the driving motor 2 is stopped, the electromagnetic valve 15 is closed, and the whole filtering device stops working. At this time, the filtering device can be checked and maintained, such as cleaning the impurities remaining in the filter cartridge 4, checking the wear condition of the cleaning assembly 5 and the stirring assembly 6, and the like, so as to prepare for the next filtering operation.

[0039] The driving motor 2 drives the stirring assembly 6 and the cleaning assembly 5 to work, the electromagnetic valve 15 controls the opening and closing of the discharging pipe 14, and the whole filtering process can be controlled through an automatic control system. According to the preset filtering time, raw material flow and other parameters, the automatic system can automatically start and stop the filtering device, realize the automatic filtering operation without manning, reduce the workload of manual operation and human error, and improve the stability and reliability of production.

[0040] The above-described embodiments only express certain implementation manners of the present application, the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application; it should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application; therefore, the protection scope of the present application patent should be subject to the appended claims.
