Description

Technical Field

[0001] This utility model belongs to the field of rubber production technology, and in particular relates to an anti-clogging filter structure for a filter press. Background Technology

[0002] Rubber is a highly elastic polymer material widely used in industry, transportation, medical care, and daily life. The production process of rubber generally involves three steps: raw material preparation, polymerization reaction, and post-processing. Filtration of raw materials is an important step in raw material preparation. To facilitate the filtration of rubber raw materials, a rubber filter is usually used. A rubber filter generally consists of a transmission system, an extrusion structure, a rubber filtering structure, a heating structure, and auxiliary structures. The rubber filtering structure is one of the important components of the rubber filter and is mainly used to filter the rubber material.

[0003] The existing patent announcement number CN222920904U discloses a filter equipment for producing high-temperature resistant PU filter adhesive, including a support frame. A drive motor is provided on the upper left side of the support frame, and a material cylinder is provided on the right side of the drive motor. A spiral rotating rod is provided concentrically inside the material cylinder, and an anti-clogging filter structure is provided on the right side of the material cylinder. The anti-clogging filter structure includes a movable shell, and the material cylinder is sleeved on the inner surface of the movable shell. A groove is provided on the inner circumferential surface of the movable shell, and a filter disc is provided in the groove.

[0004] However, it still has the following drawbacks in practical use:

[0005] The aforementioned adhesive filtering equipment filters the adhesive through filter discs 1 and 2, and cleans the filter holes 1 and 2 through cleaning columns 1 and 2. However, in practice, the small size and large number of filter holes 1 and 2 result in a large number of cleaning columns 1 and 2 required, leading to a high overall cost. Furthermore, it is not easy to prevent the adhesive from solidifying inside the filter holes 1 and 2 during the filtration process, thus reducing its practicality.

[0006] To address these issues, we provide an anti-clogging filter structure for a filter press. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Example 1

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this is the first embodiment of the present invention. This embodiment provides an anti-clogging filter structure for a filter press, including a filter head 1. One end of the filter head 1 is externally connected to the filter press. Both sides of the front and rear end faces of the filter head 1 are welded with protrusions 101. Both sides of the interior of the filter head 1 are provided with filter components 2. The filter components 2 include a mounting ring 201, a metal filter plate 202, a mounting plate 203, and a conductive post 204. The conductive post 204 heats the metal filter plate 202, making the temperature of the metal filter plate 202 similar to that of the adhesive, thereby preventing the adhesive from solidifying on the metal filter plate 202. This solves the problem of existing methods that are inconvenient to prevent the adhesive from solidifying on the metal filter plate 202.

[0034] Specifically, the mounting ring 201 is fixedly connected to both sides of the inside of the filter head 1. Metal filter plates 202 are fixedly connected to the inside of the mounting ring 201. The mounting plate 203 is fixedly connected to the protrusion 101. Conductive posts 204 penetrate through the upper and lower ends of the end face of the mounting plate 203. One end of the conductive post 204 penetrates through the through hole 201d on the mounting ring 201 and abuts against the metal filter plate 202. The mounting ring 201 is used to install the metal filter plate 202 inside the filter head 1. The metal filter plate 202 is used to filter the glue material passing through the filter head 1. The mounting plate 203 is used to install the conductive posts 204. The conductive posts 204 are used to energize the metal filter plate 202, causing the metal filter plate 202 to heat up.

[0035] Furthermore, both sides of the top and bottom of the filter head 1 are threaded with mounting rods 201a. The end of the mounting rod 201a located on the outside of the filter head 1 is fixedly connected to a limit plate 201b, and the end of the mounting rod 201a located on the inside of the filter head 1 is threaded into the threaded blind holes 201c located at the top and bottom of the mounting ring 201, respectively.

[0036] The mounting plate 203 has ear seats 203a welded to its top and bottom. The ear seats 203a are respectively attached to the top and bottom of the protrusion 101. The top and bottom of the protrusion 101 have first fixing rods 102 welded to their top and bottom. The end of the first fixing rod 102 away from the protrusion 101 passes through the ear seat 203a and is threaded to a first fastening nut 103. The first fastening nut 103 is respectively attached to the ear seat 203a. An insulating sleeve 204a is fitted on the outer wall of the conductive post 204. The other end of the conductive post 204 is fixedly connected to a terminal post 204b.

[0037] The operation process of this embodiment is as follows: the conductive post 204 is connected to the positive and negative terminals of the external power supply through the terminal post 204b, so that the current flows through the metal filter plate 202. Then, under the resistance of the metal filter plate 202, the metal filter plate 202 heats up itself, causing the adhesive solidified in the filter holes of the metal filter plate 202 to remelt, thus preventing the metal filter plate 202 from being blocked due to the solidification of the adhesive.

[0038] Example 2

[0039] Please see Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, this is the second embodiment of the present invention.

The backflushing component 3 includes a mounting frame 301, a lifting plate 302, a U-shaped frame 303, and a backflushing pipe 304. The lifting plate 302 and the U-shaped frame 303 drive the backflushing pipe 304 to rise and fall, and the backflushing pipe 304 backflushes the filter structure, thus solving the problem of the existing filter structure being difficult to unclog.

[0040] Specifically, the mounting frame 301 is fixedly connected to the top of the filter head 1. A lifting plate 302 is movably connected above the mounting frame 301. Connecting rods 302a are fixedly connected to both sides of the lower surface of the lifting plate 302. The bottom ends of the connecting rods 302a extend to the inside of the mounting frame 301 and are fixedly connected to a U-shaped frame 303. A backflush pipe 304 is fixedly connected inside the U-shaped frame 303. Multiple backflush nozzles 304a are fixedly connected to both sides of the backflush pipe 304 at equal intervals. The internal space of the mounting frame 301 is interconnected with the internal space of the filter head 1. The mounting frame 301 is used to install the lifting plate 302 and other structures on the filter head 1. The lifting plate 302 is used to drive the U-shaped frame 303 and the backflush pipe 304 to move up and down. The connecting rod 302a is used to connect the lifting plate 302 and the U-shaped frame 303. The U-shaped frame 303 is used to install the backflush pipe 304 and drive the backflush pipe 304 to move synchronously. The backflush pipe 304 and the backflush nozzle 304a are used to provide compressed air into the filter head 1 to clear the blocked filter holes.

[0041] Furthermore, a connecting plate 302b is welded to the bottom end of each connecting rod 302a. The connecting plate 302b is respectively attached to the front and rear end faces of the U-shaped frame 303. A second fixing rod 303a is welded to the front and rear end faces of the U-shaped frame 303. The end of the second fixing rod 303a away from the U-shaped frame 303 passes through the connecting plate 302b and is threadedly connected to a second fastening nut 303b. The second fastening nut 303b is attached to the connecting plate 302b.

[0042] A connecting pipe 304b passes through the center of the surface of the lifting plate 302. The bottom end of the connecting pipe 304b extends to the inside of the mounting frame 301 and is fixedly connected to the air inlet of the backflow pipe 304. A threaded rod 305 is rotatably connected to the top side of the mounting frame 301 through an L-shaped bracket 305a. A slider 305d is threadedly connected to the threaded rod 305. One side of the outer wall of the slider 305d is fixedly connected to the center position of one side of the outer wall of the lifting plate 302.

[0043] The bottom end of the vertical support arm of the L-shaped frame 305a is fixedly connected to the top side of the mounting frame 301. The horizontal support arm of the L-shaped frame 305a is fixedly connected to the drive motor 305c via the motor frame 305b. The output shaft of the drive motor 305c is fixedly connected to the top end of the threaded rod 305. The bottom end of the threaded rod 305 is rotatably connected to the top of the mounting frame 301.

[0044] The rest of the structure is the same as in Example 1.

[0045] The operation process of this embodiment is as follows: Start the drive motor 305c. The drive motor 305c drives the lifting plate 302 to move through the threaded rod 305 and the slider 305d. The lifting plate 302 drives the U-shaped frame 303 and the backflush pipe 304 to move through the connecting rod 302a. This causes the backflush pipe 304 to move into the interior of the filter head 1. The backflush pipe 304 is then connected to an air compressor through the connecting pipe 304b and the hose. Compressed air is then delivered into the filter head 1 through the backflush pipe 304 and the backflush nozzle 304a. The compressed air is used to clear the blocked filter holes.
