Description

Technical Field

[0001] The utility model relates to the technical field of waste paper, in particular to a slag removal filter for waste paper. Background Art

[0002] Waste paper refers to recyclable and renewable resources that are discarded after use in production and life, including various high-grade paper, yellow cardboard, waste cardboard boxes, trimming paper, packing paper, paper for enterprises and units, paper for engineering projects, books, periodicals and newspapers, etc.

[0003] In order to achieve better environmental protection needs, waste paper will be recycled and reused after use. Before recycling, the waste paper will be crushed to a certain size. There will inevitably be some waste residue after the crushed waste paper. In order to better recycle and reuse it, a residue removal filter will be used to filter the waste residue.

[0004] Currently, most of the slag removal filters on the market achieve the ultimate filtering purpose by making the filter plate vibrate under the action of a vibration motor. However, the vibration motor is prone to wear due to long-term vibration use, which requires frequent replacement of the vibration motor when the filter is used, increasing costs. In addition, the waste residue on the filter plate will clog the filter holes after long-term use, thereby affecting the passability of the waste paper residue and reducing the filtration efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a waste paper slag filter to solve the problem that the existing slag filter mentioned in the above background technology mostly achieves the ultimate filtering purpose by making the filter plate vibrate under the action of a vibration motor. However, the vibration motor is easy to wear out after long-term vibration use, so that the vibration motor needs to be frequently replaced when the filter is used, which increases the cost. In addition, the waste residue of the filter plate will clog the filter hole after long-term use, thereby affecting the passability of the waste paper residue and reducing the filtering efficiency.

[0012] In the utility model, the first motor is started to drive the transmission shaft to drive the cam to rotate, the insertion rod moves in the annular groove on the cam surface and drives the sliding rod to slide in the limit rod. As the cam continues to rotate, the sliding rod drives the impact rod to do reciprocating motion, thereby intermittently hitting the connecting rod. The connecting rod is forced to squeeze the spring. At the same time, the sliding rod is forced to drive the filter frame to slide up and down along the slide groove, so that the waste residue in the filter frame is filtered by shaking up and down, thereby meeting better usage requirements, and the motor can reduce the loss caused by vibration and increase the service life.

[0013] In the utility model, the second motor is started to drive the ball screw to rotate, and the external slider then drives the sliding plate and the scraper to reciprocate along the surface of the filter screen in the filter frame, so that the scraper scrapes the waste residue in the filter holes of the filter screen, avoiding the filter holes from being blocked due to long-term use, thereby affecting the passability of the waste residue, and improving the filtration efficiency.

The bottom of the limit rod 508 is fixedly connected with an impact rod 509, the inner wall of the installation box 501 is fixed with a support plate 5010, the top of the support plate 5010 is fixedly connected with a spring 5011, the other end of the spring 5011 is connected with a connecting rod 5012, the elastic performance of the spring 5011 itself drives the connecting rod 5012 to perform an extrusion and reset movement, the end of the connecting rod 5012 is fixed with a sliding rod 5013, the sliding rod 5013 is fixedly connected to the filter frame 4, and the sliding rod 5013 is slidably connected in the slide groove 3.

[0029] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the surface of the cam 505 is provided with an annular groove for facilitating the movement of the insertion rod 506 , and the annular groove provides a margin for the movement of the insertion rod 506 , so that the sliding rod 507 sleeved on the outside of the insertion rod 506 reciprocates with the rotation of the cam 505 .

[0030] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the impact rod 509 and the connecting rod 5012 are arranged at the same horizontal vertical plane. Through this design, the sliding rod 507 can drive the impact rod 509 to hit the connecting rod 5012 during the reciprocating motion, thereby driving the filter frame 4 installed at the end of the connecting rod 5012 through the sliding rod 5013 to shake and filter the waste residue.

[0031] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the slag removal mechanism 6 includes a second motor 601 fixed to the side wall of the filter frame 4, and a ball screw 602 is fixed to the output end of the second motor 601 through a coupling. It should be noted that the coupling is a prior art technology, and its specifications and models need to be selected and determined according to the actual specifications of the second motor 601. The specific selection calculation method adopts the prior art in this field, so it is not elaborated in detail. The outer sleeve of the ball screw 602 is provided with a sliding block 603, and the end of the sliding block 603 is connected to a sliding plate 604.

[0034] The use method and advantages of the utility model: When the waste paper slag removal filter is working, the working process is as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, waste is poured into the waste paper filter body 1 through the feed hopper 2 and falls into the filter frame 4, and the first motor 503 is started to drive the transmission shaft 504 to drive the cam 505 to rotate. When the cam 505 rotates, the insertion rod 506 moves in the annular groove on its surface, and at the same time, the sliding rod 507 sleeved on the outside of the insertion rod 506 slides in the limiting rod 508. When the sliding rod 507 slides, it drives the impact rod 509 at the bottom to impact the connecting rod 5012, and the connecting rod 5012 is forced to squeeze the spring 5011. As the cam 505 continues to rotate, the sliding rod 507 and the impact rod 509 make reciprocating motions and intermittently impact the connecting rod 5012, and through the elastic performance of the spring 5011 itself, the sliding rod 5013 at the end of the connecting rod 5012 drives the filter frame 4 to swing back and forth along the slide groove 3, thereby achieving the effect of filtering waste residues and meeting better usage requirements, and the motor can reduce the loss caused by vibration and improve the service life.

[0036] The filter holes of the filter 401 will be clogged with waste residues after long-term use. To clean it, the second motor 601 is started to drive the ball screw 602 to rotate. During the rotation, the slider mounted on the outside thereof slides and drives the scraper 606 at the bottom of the sliding plate 604 to perform horizontal reciprocating motion along the surface of the filter 401. At the same time, the limiting slider 605 on the side wall of the sliding plate 604 slides along the side wall of the filter frame 4, so that the scraper 606 scrapes the waste residues in the filter holes of the filter 401, thereby avoiding the filter holes of the filter 401 being clogged due to long-term use, thereby affecting the passability of the waste residues and improving the filtering efficiency.
