Description

Technical Field

[0001] This utility model relates to a filter press with an easy-to-disassemble filter screen. Background Technology

[0002] Thermoplastic elastomers are a class of materials that exhibit the elasticity and flexibility of traditional vulcanized rubber at room temperature, while being able to be processed and recycled like thermoplastic plastics at high temperatures. These materials combine the advantages of rubber and plastics, possessing the high elasticity and aging resistance of rubber, as well as the easy processing and reprocessability of plastics.

[0003] Because thermoplastic elastomers may contain large impurities, unmelted particles, gel points, or other foreign matter, they need to be heated and melted before being filtered to improve the appearance quality of the product, enhance the consistency and stability of the material, and thus help ensure the stability of product quality.

[0004] In the use of a filter press, the filter screen is a key filtration element, and its performance directly affects the filtration effect and production efficiency. Currently, most traditional filter presses use a fixed or bolt-connected filter screen installation structure. Although this can meet the basic filtration requirements to a certain extent, it has many shortcomings in actual use. For example, the filter screen is prone to clogging after long-term use and needs to be replaced or cleaned regularly. The existing filter screen disassembly and assembly process is cumbersome and complicated, which is not only time-consuming and labor-intensive, but may also cause damage to the filter screen or equipment due to improper disassembly. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a filter press that facilitates the cleaning of the filter screen by removing the disassembly part from the housing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a motor, a housing, a filter screen located on the rear side of the housing, and a feed hopper located on the top of the housing and communicating with the interior of the housing. The motor is fixedly mounted with an auger inserted into the housing, and also includes a disassembly and assembly part detachably connected to the rear side of the housing. The filter screen is located on the disassembly and assembly part.

[0007] The present invention is further configured such that: the outer periphery of the housing is provided with an external thread, the disassembly part is provided with a connecting ring for fitting the housing, and the connecting ring is provided with a threaded groove corresponding to the external thread.

[0008] The present invention is further configured to include a fixing ring made of rubber. The disassembly and assembly part includes a left mating plate, a right mating plate, and a connecting section located between the connecting ring and the left and right mating plates. The left and right mating plates are rotatably mounted on the left and right sides of the connecting section, respectively. The filter screen includes a first mounting section detachably connected to the left mating plate and a second mounting section detachably connected to the right mating plate. The fixing ring is sleeved around the middle of the left and right mating plates and is fastened to the left and right mating plates.

[0009] The present invention is further configured such that: the left mating plate is provided with a plurality of left limiting blocks protruding circumferentially, the right mating plate is provided with a plurality of right limiting blocks protruding circumferentially, and the fixing ring is provided with a left limiting slot and a right limiting slot respectively corresponding to each left limiting block and the right limiting block.

[0010] The present invention is further configured such that each of the left limiting blocks is arranged in a trapezoidal shape with a narrow outer edge and a wide inner edge, and the shape and size of each of the right limiting blocks are the same as those of the left limiting blocks.

[0011] The present invention is further configured such that: the left mating plate is provided with a left mounting groove for the first mounting section to be installed, and a connecting groove is provided on both the front and rear sides of the left mounting groove; and the left mating plate is provided with a limiting plate on both the left and right sides of the first mounting section.

[0012] The present invention is further configured such that: the left mating plate is provided with positioning blocks protruding on both the upper and lower sides of the first mounting section, and the first mounting section is provided with positioning slots corresponding to each positioning block.

[0013] By adopting the above technical solution, after the motor is started, the output shaft of the motor can drive the rod on the auger (i.e., screw conveyor) to rotate, thereby causing the blades on the rod to rotate. Under the action of friction between the material and the screw blades and the shell, the material is pushed forward and to the right along the shell, thus realizing the material conveying. The working principle and wiring method of the motor will not be specifically explained here. As the heated and molten thermoplastic elastomer enters the feed hopper, it is pushed to the right by the rotation of the auger and can then move closer to the filter screen on the right. A screen or filter screen or other device is used to filter the molten material. The molten elastomer in its molten state is effectively filtered through a fine filter medium to remove impurities, thereby improving the product's appearance quality, enhancing material consistency and stability, and helping to ensure stable product quality. With prolonged use of the filter press, the disassembly section on the right side can be removed from the housing and moved to fall under the water flow to clean the filter screen inside. After cleaning, the disassembly section can be reinstalled to continue using the filter screen. Therefore, the detachable connection between the disassembly section and the housing facilitates the cleaning of the filter screen. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] like Figures 1-6 As shown, this utility model discloses a filter press with an easy-to-disassemble filter screen, including a motor 1, a housing 2, a filter screen 3 located on the rear side of the housing 2, and a feed hopper 4 located on the top of the housing 2 and communicating with the interior of the housing 2. The motor 1 is fixedly installed with an auger 5 inserted into the housing 2 by means of key connection or other means. Sealing rings can also be installed on the front and rear sides of the insertion position between the output shaft of the motor 1 and the housing 2, thereby improving the sealing performance at this position. It also includes a disassembly and assembly part 6 that can be detachably connected to the rear side of the housing 2 by means of bolts, buckles, or other means. The filter screen 3 is located on the disassembly and assembly part 6. The auger 5 (this is prior art, and the specific structure is not described in detail) is a continuous conveying device that uses rotating spiral blades to push materials forward in the closed housing 2. After the motor 1 is started, the output shaft of the motor 1 can drive the rod on the auger 5 to rotate, thereby rotating the blade part on the rod. Under the action of friction between the heated and molten elastic body, the spiral blades, and the housing 2, The material is pushed backward along the shell 2 to achieve material conveying. The working principle and wiring method of the motor 1 will not be explained in detail here. After the heated and molten thermoplastic elastomer enters the feed hopper 4, it is pushed to the right by the rotation of the auger 5 and can approach the filter screen 3 on the right. Using a screen or filter, the molten elastomer in the molten state is passed through a fine filter medium to effectively remove impurities, thereby improving the appearance quality of the product, enhancing the consistency and stability of the material, and helping to ensure the stability of product quality. With the long-term use of the filter press, after the disassembly part 6 on the right is removed from the shell 2, it can be moved and fall under the water flow to clean the filter screen 3 inside the disassembly part 6. After cleaning, the disassembly part 6 can be reinstalled to continue using the filter screen 3. Therefore, the detachable connection between the disassembly part 6 and the shell 2 provides convenience for cleaning the filter screen 3.

[0030] The outer periphery of the housing 2 is provided with an external thread 21, and the disassembly and assembly part 6 is provided with a connecting ring 61 that fits onto the housing 2. The connecting ring 61 is provided with a threaded groove 611 corresponding to the external thread 21. By providing an external thread 21 on the outer periphery of the housing 2 and a threaded groove 611 at the corresponding position on the connecting ring 61 on the disassembly and assembly part 6, the disassembly and assembly of the housing 2 and the disassembly and assembly part 6 are facilitated.

[0031] The system also includes a retaining ring 7 made of rubber. The disassembly / assembly part 6 includes a left mating plate 62, a right mating plate 63, and a connecting section 64 located between the connecting ring 61 and the left and right mating plates 62 and 63, respectively. The left and right mating plates 62 and 63 are rotatably mounted on the left and right sides of the connecting section 64, respectively. The filter screen 3 includes a first mounting section 31 that is detachably connected to the left mating plate 62 by fastening, bolts, or other means, and a second mounting section 32 that is detachably connected to the right mating plate 63 by fastening, bolts, or other means. The retaining ring 7 is sleeved on the left mating plate 6. 2. The right mating plate 63 is circumferentially connected to the left mating plate 62 and the right mating plate 63. Since the left mating plate 62 and the right mating plate 63 are rotatably mounted on the connecting plate, by applying an outward force to the fixing ring 7 on the left mating plate 62 and the right mating plate 63, they can be removed from the left mating plate 62 and the right mating plate 63. This allows the left mating plate 62 and the right mating plate 63 to be rotated, thereby removing the first mounting section 31 detachable from the left mating plate 62 and the second mounting section 32 detachable from the right mating plate 63. Furthermore, because the filter screen 3 includes... The first mounting section 31 and the second mounting section 32 are connected, so removing the first mounting section 31 and the second mounting section 32 facilitates cleaning of both parts of the filter screen 3. When only partial cleaning of the filter screen 3 is needed, the filter screen 3 at that location can be removed without removing the entire disassembly section 6. After cleaning, by rotating to the left, one end of the left mating plate 62 and the right mating plate 63 abuts against the connecting section 64. Then, the retaining ring 7 is bent to fit over the middle of the left mating plate 62 and the right mating plate 63, completing the fastening connection. This allows the retaining ring 7 to... The filter screen 3 is stably positioned between the left mating plate 62 and the right mating plate 63, meaning that the left mating plate 62 and the right mating plate 63 will not rotate arbitrarily without the action of external force, thus ensuring that the filter screen 3 can function as a filter for adhesive. At the same time, due to the presence of the fixing ring 7, as the auger 5 rotates and drives the heated and molten elastic body to move towards the filter screen 3, its movement will not cause the left mating plate 62 and the right mating plate 63 to separate due to the force of the filter screen 3, thus ensuring that the two are stably connected. In addition, the connection strength between the left mating plate 62 and the right mating plate 63 can be further improved by connecting the left mating plate 62 and the right mating plate 63 with bolts.

[0032] The left mating plate 62 is circumferentially provided with several left limiting blocks 621, and the right mating plate 63 is circumferentially provided with several right limiting blocks 631. The fixing ring 7 is respectively provided with a left limiting slot 71 and a right limiting slot 72 corresponding to each left limiting block 621 and right limiting block 631. During the process of bending the fixing ring 7 to fit into the middle position of the left mating plate 62 and the right mating plate 63, each left limiting block 621 and right limiting block 631 will respectively enter into the corresponding left limiting slot 71 and right limiting slot 72. The right limiting slot 72 is located inside the right limiting slot, so that the retaining ring 7 can be stably fitted around the left mating plate 62 and the right mating plate 63 without the action of external force. This prevents the left mating plate 62 and the right mating plate 63 from rotating to the right and separating from the connecting section 64. When it is necessary to rotate them to the right to remove the first mounting section 31 and the second mounting section 32 for cleaning, the retaining ring 7 can be bent to separate the left limiting slot 71 and the right limiting slot 72 from the left limiting plug 621 and the right limiting plug 631.

[0033] Preferably, each of the left limiting blocks 621 is arranged in a trapezoidal shape with a narrower outer side and a wider inner side. The shape and size of each of the right limiting blocks 631 are the same as those of the left limiting blocks 621. The trapezoidal design of the left limiting blocks 621 and the right limiting blocks 631 (narrower outer side and wider inner side) ensures that when the fixing ring 7 is bent and inserted between the left mating plate 62 and the right mating plate 63, the left limiting slot 71 and the right limiting slot 72 on the fixing ring 7 will first be located outside each of the left limiting blocks 621 and the right limiting blocks 631. Since the length of the outer end face of the left and right limiting blocks is less than the length of the inner end face, it facilitates the alignment of the left limiting slot 71 and the right limiting slot 72 with the left limiting blocks 621 and the right limiting blocks 631.

[0034] The left mating plate 62 is provided with a left mounting groove 622 for the first mounting section 31 to be inserted, and connecting grooves 623 are provided on both the front and rear sides of the left mounting groove 622. Limiting plates 624 are provided on both the left and right sides of the left mating plate 62 for the first mounting section 31. During the process of inserting the first mounting section 31 into the left mounting groove 622 of the left mating plate 62, after the first mounting section 31 is completely inserted into the left mounting groove 622, the limiting plates 624 on the left and right sides will be located on the front and rear sides of the first mounting section 31 respectively, so that the first mounting section 31 cannot fall off the left mounting groove 622 without the action of external force. At the same time, due to the existence of each connecting groove 623, the rubber that is heated and melted by the filter screen 3 can pass through each connecting groove 623 and reach the right side of the disassembly part 6 and be collected.

[0035] The left mating plate 62 has positioning blocks 625 protruding from both the upper and lower sides of the first mounting section 31. Each positioning block 625 in the first mounting section 31 has a corresponding positioning slot 311. Due to the presence of the positioning blocks 625, during the process of inserting the first mounting section 31 into the left mounting groove 622, the portion initially in contact with each positioning block 625 must forcibly pass over the positioning blocks 625 to allow each positioning block 625 to be inserted into its corresponding positioning slot 311 in the first mounting section 31. Without external force, the left and right sides of the first mounting plate are restricted by the positioning plate 624 and are restricted forward by the positioning blocks 625, making it difficult for them to fall out of the left mating plate 62, thus facilitating the fixation of the first mounting section 31 to the left mating plate 62. When the fixing ring 7 is removed and the left mating plate 62 is rotated to the right, the positioning slots 311 and the positioning blocks 625 can be separated by applying a forward force to the first mounting section 31, thereby removing the first mounting section 31 from the left mounting slot 622 and facilitating cleaning.

[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
