Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a self-cleaning outlet filter for the production of environmentally friendly plasticizers. Background Technology

[0002] The self-cleaning outlet filter for environmentally friendly plasticizer production is a high-efficiency filtration device used in the production process of environmentally friendly plasticizers. It effectively filters impurities and particles that may be carried along with the material when it exits the reactor after the environmentally friendly plasticizers have reacted, ensuring product quality. This filter has a self-cleaning function, automatically removing impurities from the filter screen after filtration to prevent clogging and ensure consistent and stable filtration performance. Compared to traditional filters, it significantly reduces the frequency and cost of manual cleaning, improving production efficiency. In short, the self-cleaning outlet filter for environmentally friendly plasticizer production combines multiple advantages such as high-efficiency filtration, self-cleaning, and environmental friendliness, making it an indispensable key piece of equipment in the production process of environmentally friendly plasticizers.

[0003] According to Chinese Utility Model Publication No. CN222239147U, a self-cleaning filter for producing DOTP environmentally friendly plasticizers is disclosed. In this utility model, the raw material is placed on the top cover, allowing it to enter the machine housing through the feed hole and be filtered by a filter screen. A drive motor rotates the rotating arm, which in turn drives the drive gear to reciprocate via a linkage rod. The drive gear, in turn, meshes with the driven gear, accelerating the rotation of the shaft. The shaft then drives the disc, connecting column, and filter screen to reciprocate, thus using centrifugal force to remove filter residue from their surfaces. Finally, a water pump is activated to introduce water into the outlet. Inside the cylinder, water is sprayed out from the outlet nozzle to wash the filter residue, further filtering the residual material on the surface and dispersing the filter residue to prevent clogging. When the disc rotates, it drives the horizontal plate, square plate, square frame and counterweight plate to move in a circular motion. The counterweight plate is thrown outward under the action of centrifugal force and compresses the compression spring. When the disc reciprocates, the rotation speed will experience a cycle of acceleration and deceleration, which causes the centrifugal force of the counterweight plate to increase and decrease in a cycle. This drives the round rod to move back and forth relative to the disc. The round rod, through cooperation with the guide hole, drives the cleaning arm to rotate back and forth around the connecting column, thereby scraping the top and bottom of the filter screen to prevent filter residue from clogging. The filtered material is discharged by activating the control valve.

[0004] However, there are some issues to consider when implementing the above technical solutions: First, some impurities that are similar in size to the filter screen will get stuck in the mesh of the filter screen. After the cleaning arm sweeps over the filter screen, it cannot remove the impurities from the mesh. After long-term use, this will cause the mesh to become clogged and affect the filtration efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a self-cleaning outlet filter for the production of environmentally friendly plasticizers, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning outlet filter for producing environmentally friendly plasticizers, comprising a filter cylinder, a liquid inlet and outlet mechanism, and a self-cleaning filtration mechanism. A column is welded to the outer bottom of the filter cylinder, a controller is fixedly connected to the front of the filter cylinder, the liquid inlet and outlet mechanism is fixedly connected to the center of the upper and lower ends of the filter cylinder, and the self-cleaning filtration mechanism is fixedly connected to the left side and the inside of the filter cylinder.

[0007] Preferably, the liquid inlet and outlet mechanism includes an upper tee pipe, a raw liquid inlet solenoid valve, a cleaning liquid inlet solenoid valve, a lower tee pipe, a raw liquid outlet solenoid valve, and a cleaning liquid outlet solenoid valve. The upper tee pipe is fixedly connected to the center of the top of the filter cylinder, the raw liquid inlet solenoid valve is fixedly connected to the top of the upper tee pipe, and the cleaning liquid inlet solenoid valve is fixedly connected to the right side of the upper tee pipe. The lower tee pipe is fixedly connected to the center of the bottom of the filter cylinder, the raw liquid outlet solenoid valve is fixedly connected to the right side of the lower tee pipe, and the cleaning liquid outlet solenoid valve is fixedly connected to the bottom of the lower tee pipe. The raw liquid inlet solenoid valve, the cleaning liquid inlet solenoid valve, the raw liquid outlet solenoid valve, and the cleaning liquid outlet solenoid valve are electrically connected to the controller.

[0008] Preferably, the filter self-cleaning mechanism includes a motor, a drive shaft, a rotating frame, an isolation rod, a filter screen, a vibrator, a support frame, a sealing strip, and a sealing groove. The motor is fixedly connected to the left side of the filter cylinder. The motor is electrically connected to the controller. The output shaft of the motor is fixedly connected to one end of the drive shaft. The other end of the drive shaft is welded to the rotating frame, which is rotatably connected to the filter cylinder.

[0009] Preferably, an isolation rod is fixedly connected inside the rotating frame, and a filter screen is fixedly connected to the inner side of the isolation rod.

[0010] Preferably, a vibrator is fixedly connected to the bottom end of the isolation rod, and the vibrator is electrically connected to the controller.

[0011] Preferably, the filter cartridge has a support frame welded inside, and two sets of the support frame are provided, with the support frame corresponding to the position of the rotating frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model incorporates a vibrator. When the vibrator operates, the vibration is transmitted through an isolation rod to dislodge the filter screen, preventing the accumulation of impurities that would affect subsequent use. The model also includes a motor, a drive shaft, and a rotating frame. When the motor operates, it drives the drive shaft to rotate, which allows the rotating frame to flip, switching between filtration and self-cleaning modes. After flipping, the impurities can fall directly into the lower half of the filter cylinder.

[0015] This invention improves the stability of the rotating frame during filtration by providing a support frame, preventing plasticizer impact from causing the frame to shift. The use of a sealing strip and sealing groove, in conjunction with the sealing strip, prevents unfiltered plasticizer from passing through the gap between the support frame and the rotating frame, thus maintaining its purity. A liquid inlet and outlet mechanism is also included. During filtration, the raw liquid inlet and outlet solenoid valves are open, while the cleaning liquid inlet and outlet solenoid valves are closed. When cleaning is required, the cleaning liquid inlet solenoid valve opens, while the raw liquid inlet, outlet, and cleaning liquid outlet solenoid valves close. Finally, the cleaning liquid outlet solenoid valve opens to drain the waste liquid. Attached Figure Description

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.

[0025] Please see Figure 1-4 An embodiment of this utility model provides: an environmentally friendly plasticizer production self-cleaning outlet filter, including a filter cylinder 1, a liquid inlet and outlet mechanism 4 and a filter self-cleaning mechanism 5. A column 2 is welded to the bottom outer side of the filter cylinder 1, a controller 3 is fixedly connected to the front of the filter cylinder 1, the liquid inlet and outlet mechanism 4 is fixedly connected to the center of the upper and lower ends of the filter cylinder 1, and the filter self-cleaning mechanism 5 is fixedly connected to the left side and inside of the filter cylinder 1.

[0026] Specifically, the liquid inlet and outlet mechanism 4 includes an upper three-way pipe 401, a raw liquid inlet solenoid valve 402, a cleaning liquid inlet solenoid valve 403, a lower three-way pipe 404, a raw liquid outlet solenoid valve 405, and a cleaning liquid outlet solenoid valve 406. The upper three-way pipe 401 is fixedly connected to the center of the top of the filter cylinder 1. The raw liquid inlet solenoid valve 402 is fixedly connected to the top of the upper three-way pipe 401, and the cleaning liquid inlet solenoid valve 403 is fixedly connected to the right side of the upper three-way pipe 401. The lower three-way pipe 404 is fixedly connected to the center of the bottom of the filter cylinder 1. The raw liquid outlet solenoid valve 402 is fixedly connected to the right side of the lower three-way pipe 404, and the cleaning liquid outlet solenoid valve 406 is fixedly connected to the bottom of the lower three-way pipe 404. The washing liquid drain solenoid valve 406, the raw liquid inlet solenoid valve 402, the cleaning liquid inlet solenoid valve 403, the raw liquid drain solenoid valve 405, and the cleaning liquid drain solenoid valve 406 are electrically connected to the controller 3. During filtration, the raw liquid inlet solenoid valve 402 and the raw liquid drain solenoid valve 405 are open, and the cleaning liquid inlet solenoid valve 403 and the cleaning liquid drain solenoid valve 406 are closed to perform filtration. When cleaning is required, the cleaning liquid inlet solenoid valve 403 is open, and the raw liquid inlet solenoid valve 402, the raw liquid drain solenoid valve 405, and the cleaning liquid drain solenoid valve 406 are closed to perform cleaning. Finally, the cleaning liquid drain solenoid valve 406 is opened to drain the waste liquid.

[0027] Specifically, the filter self-cleaning mechanism 5 includes a motor 501, a drive shaft 502, a rotating frame 503, an isolation rod 504, a filter screen 505, a vibrator 506, a support frame 507, a sealing strip 508, and a sealing groove 509. The motor 501 is fixedly connected to the left side of the filter cylinder 1. The motor 501 is electrically connected to the controller 3. The output shaft of the motor 501 is fixedly connected to one end of the drive shaft 502. The other end of the drive shaft 502 is welded to the rotating frame 503. The rotating frame 503 is rotatably connected to the filter cylinder 1. When the motor 501 works, it drives the drive shaft 502 to rotate, which can cause the rotating frame 503 to flip, switching between filtration and self-cleaning states. After flipping, impurities can fall directly into the lower half of the filter cylinder 1.

[0028] Specifically, an isolation rod 504 is fixedly connected inside the rotating frame 503, and a filter screen 505 is fixedly connected to the inner side of the isolation rod 504. The filter screen 505 filters out impurities in the plasticizer.

[0029] Specifically, a vibrator 506 is fixedly connected to the bottom of the isolation rod 504. The vibrator 506 is electrically connected to the controller 3. When the vibrator 506 works, it vibrates through the isolation rod 504 to dislodge the filter screen 505, thus preventing the accumulation of impurities in the filter screen 505 from affecting subsequent use.

[0030] Specifically, a support frame 507 is welded inside the filter cartridge 1. Two sets of support frames 507 are provided, and the support frames 507 correspond to the position of the rotating frame 503. The support frames 507 can improve the stability of the rotating frame 503 during filtration and prevent the rotating frame 503 from shifting due to plasticizer impact.

[0031] Specifically, a sealing strip 508 is adhered to the surface of the support frame 507, and sealing grooves 509 are provided on both sides of the rotating frame 503. The sealing grooves 509 and the sealing strips 508 are tightly fitted together. The cooperation between the sealing grooves 509 and the sealing strips 508 can prevent unfiltered plasticizer from passing through the gap between the support frame 507 and the rotating frame 503, thus affecting the purity of the plasticizer.

[0032] Working principle: During filtration, the raw liquid inlet solenoid valve 402 and raw liquid outlet solenoid valve 405 are open, while the cleaning liquid inlet solenoid valve 403 and cleaning liquid outlet solenoid valve 406 are closed, initiating filtration. The filter screen 505 then filters impurities from the plasticizer. The support frame 507 improves the stability of the rotating frame 503 during filtration, preventing the rotating frame 503 from shifting due to plasticizer impact. The sealing groove 509 cooperates with the sealing strip 508 to prevent unfiltered plasticizer from passing through the gap between the support frame 507 and the rotating frame 503, thus avoiding interference. Regarding the purity of the plasticizer, when cleaning is required, the motor 501 drives the transmission shaft 502 to rotate, causing the rotating frame 503 to flip. The cleaning fluid inlet solenoid valve 403 opens, allowing the cleaning fluid to enter. At the same time, the vibrator 506 operates, vibrating through the isolation rod 504 to dislodge the impurities stuck in the filter screen 505, preventing long-term accumulation from affecting subsequent use. The original liquid inlet solenoid valve 402, the original liquid outlet solenoid valve 405, and the cleaning fluid outlet solenoid valve 406 are closed for cleaning. Finally, the cleaning fluid outlet solenoid valve 406 is opened to drain the waste liquid.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
