Problems solved by technology

Due to the clearance fit between the roller and the side baffle, part of the material enters the gap between the roller and the side baffle during the extrusion process, causing serious wear on the end surface of the roller and the side baffle, resulting in the poor sealing of the crushing chamber and affecting the powder. grinding efficiency, requiring frequent replacement of roller press side dams
However, the side baffles of the roller press are fixed on the body, so it is inconvenient to replace the side baffles and takes a long time, which seriously affects the equipment operation rate of the roller press.
At the same time, the pressure on the upper side of the side baffle is relatively small, and the wear is relatively small, and the lower part is the main wear area. However, since the side baffle is a whole piece, even if only the lower part is severely worn, it can only be stopped to replace the whole side baffle or Removal of entire side dams for repairs, resulting in greater waste and lower equipment operating rates
In addition, the wear of the material on the end surface of the roller is gradually intensified, and the gap between the replaced side baffle and the roller is getting larger and larger, and it is impossible to form a closed crushing cavity with the end surface of the roller. In the end, the entire roller can only be scrapped, resulting in higher maintenance costs

Embodiment 1

[0038] Such as figure 1 As shown, the roller press side baffle mechanism of the present invention includes a side baffle 1, a wear-resistant part 2 and a feed mechanism 4, wherein the side baffle 1 is fixed above the roller working surface 0-50 mm from the end surface of the roller, And perpendicular to the centerline of the roller; a wear-resistant part 2 is arranged on the outside of the roller press and is perpendicular to the side baffle 1. The working surface area of ​​the wear-resistant part 2 depends on the pressure. The wear-resistant part 2 can be Push from the outside of the roller press to the inside of the roller press, together with the inner side of the side baffle 1 and the working surface of the roller (not the end surface of the roller) to form a crushing cavity. Therefore, the present invention transforms the friction of the material between the traditional side baffle 1 and the end surface of the roller into the friction of the material between the side baff...

Embodiment 2

[0040] Such as figure 2 , image 3 As shown, the roller press side baffle mechanism of the present invention includes a side baffle 1, a wear-resistant part 2 and a feed mechanism 4, wherein the side baffle 1 is fixed above the roller working surface 0-50mm away from the end surface of the roller, And perpendicular to the center line of the roller; on the inner side of the side baffle 1, a wear-resistant part 2 and a feed mechanism 4 are provided, wherein the wear-resistant part 2 is vertically arranged on the center line of the side baffle 1, so that the wear-resistant part 2. It can be pushed from the inner side of the side baffle 1 along the center line on the slide rail 3 from top to bottom to below the lower edge of the side baffle 1, so that the working surface of the wear-resistant part 2 and the inner side of the side baffle 1 work together with the rollers. The surface (not the end surface of the roller) forms the crushing chamber. Therefore, the present invention ...

Embodiment 3

[0042] Such as Figure 4 As shown, this embodiment is similar to Embodiment 1, the difference is that the driving mechanism of the feed mechanism in this embodiment is a hand wheel, wherein the wear-resistant part 2 is fixedly connected with the driving mechanism, and the driving mechanism is connected with the The slide rail 3 cooperates so that the wear-resistant part 2 can move along the direction of the slide rail 3 on the slide rail 3, so that the end of the wear-resistant part 2 extends to the bottom of the side baffle plate 1 to supplement the worn part. In this example, manual control is adopted, so the driving mechanism adopts the handwheel 5, and the screw rod is connected to the hand wheel 5, so the screw rod can be driven to rotate by controlling the handwheel 5, and the wear-resistant parts are driven to move on the slide rail 3, thereby realizing Advance and retreat of wear parts. When the wear-resistant part 2 cannot form an effective crushing cavity with the w...

Abstract

The invention discloses a side baffle mechanism of a roller press, and belongs to the technical field of roller presses. According to the side baffle mechanism of the roller press, provided by the invention, a fixed side baffle is arranged on the roller press; wear-resistant elements are arranged on the outer side of the roller press or the inner side of the side baffle plate, and are connected onto a feeding mechanism; and the feeding mechanism pushes the end parts of the wear-resistant elements to extend below the baffle so as to replenish the abrasive parts of the wear-resistant elements, so that one end part of each wear-resistant element and the inner side surface of the side baffle form a crushing cavity together with a roller operating surface. The side baffle mechanism of the roller press, provided by the invention, can replenish the abrasive parts of a traditional side baffle manually or automatically; in replacement, the whole side baffle is not required to be dismounted, and only the abrasive parts are replaced; and the abrasion problem on the roller end surface can be solved effectively, thereby achieving the aims of improving the device running rate and lowering the device maintaining expense.

Description

technical field [0001] The invention relates to a side baffle plate mechanism of a roller press, which is suitable for roller presses used in cement, metallurgy, mining and other industries. Background technique [0002] Roller press is a kind of high-efficiency and energy-saving grinding equipment, which has been widely used in cement, metallurgy and ore industries. The traditional roller press consists of a pair of relatively rotating rollers and side baffles at both ends of the rollers to form a closed crushing chamber, and the material is squeezed by the rollers and then discharged from the gap between the rollers. Due to the clearance fit between the roller and the side baffle, part of the material enters the gap between the roller and the side baffle during the extrusion process, causing serious wear on the end surface of the roller and the side baffle, resulting in the poor sealing of the crushing chamber and affecting the crushing process. Grinding efficiency, which...
