Description

Technical Field

[0001] The invention relates to a screw press, in particular to a screw press for radially adjusting the gap of a filter cartridge. Background Art

[0002] The screw press squeezes out the moisture in the material, thereby reducing the moisture content of the material. The drainage holes of the traditional screw press are fixed and cannot be adjusted for different materials. The application area is narrow, and the pressure that the screw press can withstand is small. The moisture content of the material is still high after dehydration by screw pressing. Summary of the invention

[0003] In view of the above shortcomings, the applicant has conducted research and improvement, and provided a screw press for radially adjusting the gap of the filter cartridge.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A screw press for radially adjusting the gap of a filter cartridge comprises a base, an outer shell and a filter cartridge, the outer shell being connected to the base, the filter cartridge being installed in the outer shell, and the filter cartridge being composed of a plurality of filter strips, the outer shell being circumferentially provided with a plurality of mounting through hole groups, each mounting through hole group comprising a plurality of mounting through holes uniformly distributed in the circumference of the outer shell, the mounting through holes being fixedly connected with a filter strip mounting plate, the filter strip mounting plate being connected with a gap adjusting bolt, the other end of the gap adjusting bolt being threadedly connected with the filter strip, and a locking nut being connected with the gap adjusting bolt, the outer shell being located in the filter cartridge and rotatably connected with a spiral shaft for installing a spiral sheet, the spiral shaft passing through the outer shell and being connected with a motor, the outer shell being connected with a feed hopper, the feed hopper extending into the filter cartridge, a discharge port being arranged at the other end of the filter cartridge, an adjustable back pressure mechanism being arranged at the discharge port of the filter cartridge, and a discharge port and a drain port being also arranged on the lower side of the outer shell.

[0006] As a further improvement of the above technical solution:

[0007] The filter strip mounting plate is fixedly connected to the shell by bolts.

[0008] The back pressure mechanism includes a mounting sleeve connected to the spiral shaft, the mounting sleeve is connected to a back pressure adjusting bolt, the tail end of the back pressure adjusting bolt presses against one side of a spring support plate sleeved on the spiral shaft, the other end of the spring support plate supports the spring, the other end of the spring is connected to a back pressure plate sleeved on the spiral shaft, and the back pressure plate closes the discharge port of the filter cartridge.

[0009] The filter strips include an outer arc seat and an inner arc seat, and the side walls on both sides of the inner arc seat are inclined inwards, so that the gap between the filter strips is smaller inside and larger outside.

[0010] The diameter of the screw shaft increases continuously from the feed hopper position to the discharge port position.

[0011] The spacing between the spiral plates connected to the spiral shaft decreases continuously from the position of the feed hopper to the position of the discharge port.

[0012] The motor is connected to the base, the motor is connected to the synchronous wheel, and the synchronous wheel is connected to the synchronous gear of the spiral shaft through a synchronous belt.

[0013] The lower end of the shell is connected to a drainage bucket, a drainage outlet is arranged at the lower end of the drainage bucket, and the lower end of the drainage bucket is connected to a base and communicated with a water tank connected to the base.

[0014] The beneficial effects of the present invention are as follows: the screw press for radially adjusting the gap of the filter cartridge can radially adjust the position of the filter strips by rotating the gap adjusting bolt, thereby adjusting the gap between the filter strips, which can meet the dehydration treatment of different materials and has a wide range of applications. In addition, the pressure of the back pressure plate can be adjusted by an adjustable back pressure mechanism, so that the material can be opened only when it reaches the set pressure, thereby preventing the discharge of thin materials that do not meet the water content, ensuring the dehydration quality, making the material drier, and the discharged water clearer.

The tail end of the bolt 72 is pressed against one side of a spring support plate 73 sleeved on the spiral shaft 5, and the other end of the spring support plate 73 supports a spring 74. The other end of the spring 74 is connected to a back pressure plate 75 sleeved on the spiral shaft 5. The back pressure plate 75 closes the discharge port 32 of the filter cartridge 3, and the outer shell 2 is located at the lower side of the back pressure mechanism 7 to define a discharge port 23; the outer shell 2 is located at the lower side of the filter cartridge 3 and is also connected to a drainage bucket 25, and a drainage port 24 is defined at the lower end of the drainage bucket 25, and the lower end of the drainage bucket 25 is connected to the base 1, and is communicated with a water tank 8 connected to the base 1.

[0023] The diameter of the screw shaft 5 increases continuously from the feed hopper 22 to the discharge port 32, and the spacing between the spiral pieces 51 connected to the screw shaft 5 decreases continuously from the feed hopper 22 to the discharge port 32, so that the extrusion space becomes smaller and smaller, and the moisture in the material is gradually squeezed out.

[0024] When the screw press for radially adjusting the gap of the filter cartridge of the present embodiment is used, the filter strip 31 is first connected to the gap adjusting bolt 41, and the filter cartridge 3 is formed by the filter strip 31.
