Technical Field

[0001] The utility model relates to the technical field of roller presses, in particular to a roller press dust collector used in cement production. Background Art

[0002] Roller press, also known as extrusion mill, roller mill, and roller press, is a new type of cement energy-saving grinding equipment developed in the mid-1980s. Roller press is designed based on the principle of bed grinding. Its main features are high pressure, full speed, full material, and bed crushing. Roller press consists of two extrusion rollers that rotate synchronously in opposite directions, one is a fixed roller and the other is a movable roller. The material is fed from above the two rollers and is continuously brought into the roller space by the extrusion rollers. After being subjected to a high pressure of 100-150MPa, it becomes a dense cake and is discharged from the bottom of the machine.

[0003] The dust problem around the roller press is more prominent, especially at the feed port, discharge port and the contact area between the roller and the material, where a large amount of dust is easily generated, and the working range of the dust collector may not be able to fully cover the various dust points of the roller press, resulting in some dust cannot be effectively collected.

One end of the dust suction pipe 2 302 faces the discharge port 101, and the other end of the dust suction pipe 2 302 is fixedly connected to the lower left wall of the dust suction box 3 to collect dust and introduce it into the dust suction box 3. The right side of the support block 7 is fixedly connected to the right side of the inner wall of the dust suction box 3, and the dust suction pump is fixedly connected to the upper surface of the support block 7 to support and drive the dust suction process to ensure the dust suction effect. The fixing assembly 10 is respectively arranged on the bottom surface and the top surface inside the dust collecting box 3, and the filter screen plate 1 8 and the filter screen plate 2 9 are arranged inside the fixing assembly 10. The filter holes of the filter screen plate 1 8 are larger than the filter holes of the filter screen plate 2 9.

[0034] Embodiment 2:

[0035] On the basis of the first embodiment, the fixing assembly 10 comprises a base 1001, a damping rod 1002, a spring 1003 and a placement slot 1004, the placement slot 1004 is opened above the base 1001, one end of the four damping rods 1002 is respectively connected to the two sides of the placement slot 1004 in pairs, the other ends of the four damping rods 1002 are respectively connected to the two sides of the filter screen plate 8 in pairs, the two ends of the four springs 1003 are connected between the two ends of the damping rod 1002, and the connection method of the filter screen plate 9 is the same as the connection method of the filter screen plate 8.

[0036] Working principle: Dust suction pipe 1 301 and dust suction pipe 2 302 are connected to the feed bin 2 and the discharge port 101 respectively to collect dust generated by the roller press 1. Dust enters the dust box 3 through dust suction pipe 1 301 and dust suction pipe 2 302, and first encounters filter screen 1 8, where large dust particles are intercepted. The airflow continues to pass through and encounters filter screen 2 9, where finer dust is further intercepted. Clean air is filtered and discharged from the air outlet of the dust box 3. The setting of filter screen 1 8 and filter screen 2 9 achieves a multi-stage filtering effect and improves dust removal efficiency.

[0037] The damping rod 1002 and spring 1003 in the fixing assembly 10 provide stable support and buffering for the filter screen, ensuring stable filtering performance. When the motor 601 is started, the connection bar 602 and the connection block 603 rotate, so that one end of the connection block 603 abuts against the filter screen, thereby generating vibration, thereby cleaning the dust on the filter screen. The three dust collection ports 304 are located on the bottom surface of the dust collection box 3, which effectively collect dust falling from the filter screen. When the dust enters the dust collection box 5, it is discharged through the dust outlet pipe 501.
