Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of roller crushers, in particular to an anti-blocking and dust suppression device for roller crushers. Background Art
[0002] In the design of roller crushers, the discharge port is often equipped with a vertically guided tube body so that the material falls directly and is transported to the conveyor belt. However, this design brings potential problems during use. For example, the conveyor belt surface may be damaged by the direct impact of the material, thereby shortening the service life of the conveyor belt. In addition, the distance between the lower end of the tube body and the conveyor belt is often difficult to completely make up. This situation mainly manifests itself in two aspects: when the distance between the lower end of the tube body and the conveyor belt surface is large, the material may be ejected from the conveyor belt due to direct impact, resulting in material spillage and fine powder dusting; on the other hand, when the distance between the lower end of the tube body and the conveyor belt surface is small, larger materials may be blocked by the lower end of the tube body, thereby scratching the conveyor belt and making the conveyor belt unusable.

[0042] The discharge port of a roller crusher is often equipped with a vertical pipe body. The material falls directly from the discharge port and directly impacts the conveyor belt 600 at the bottom, which will shorten the service life of the conveyor belt 600. In addition, there is a certain distance between the end of the pipe body and the conveyor belt 600. Large-sized materials are prone to rebound after impact, resulting in material spillage, fine powder and dust, and blockage of the lower end of the pipe body.
[0043] In view of this, if Figure 1 As shown, this solution provides an anti-blocking and dust suppression device for a roller crusher, comprising a buffering and unloading assembly 100 and a unloading and crushing assembly 200;
[0044] The buffer blanking assembly 100 includes a stepped buffer plate 110;
[0045] The falling material crushing assembly 200 includes two roller conveyors 210 arranged opposite to each other;
[0046] The buffer discharge assembly 100 is arranged below the crushing roller 300 of the roller crusher;
[0047] The material dropping and crushing assembly 200 is disposed at the lower portion of the buffering material dropping assembly 100 .
[0048] After using this device, the stepped buffer plate 110 can effectively slow down the falling speed of the material, preventing the material from falling directly from a high place and impacting the conveyor belt 600, and the roller conveyor 210 can crush the falling large pieces of material to avoid blockage caused by large pieces of material.
[0049] like Figure 1 As shown, the buffer blanking assembly 100 is provided with at least two stepped buffer plates 110 corresponding to each other;
[0050] The side of the stepped buffer plate 110 close to the material has an inclined surface 111 that gradually slopes downward from the upper right to the bottom.
[0051] Specifically, according to the size of the roller crusher, two or four stepped buffer plates 110 can be set. When applied to a smaller roller crusher, two stepped buffer plates 110 are respectively arranged on both sides parallel to the axis of the crushing roller 300. When applied to a larger roller crusher, four stepped buffer plates 110 corresponding to each other can be set. The inclined surface 110 is inclined downward from the end close to the outer wall to the end close to the center of the material to increase the material discharge speed and avoid a large amount of material accumulation on the stepped buffer plate 110.
[0052] Preferably, the falling material breaking assembly 200 includes a hydraulic cylinder 220;
[0053] The hydraulic cylinder 220 is fixedly connected to the roller conveyor 210 .
[0054] Specifically, the hydraulic cylinder 220 is connected to the two ends of the roller conveyor through a connecting rod. Each roller conveyor 210 on both sides is provided with a hydraulic cylinder 220. The distance between the two roller conveyors 210 can be adjusted according to the actual production conditions of the material to increase the speed at which the material falls to the conveyor belt 600.
[0055] like Figure 1 As shown, a monitoring component is also included;
[0056] The monitoring assembly includes a first material level meter 410 and a second material level meter 420;
[0057] The first material level meter 410 is arranged above the second material level meter 420;
[0058] The first material level meter 410 is connected to the crushing roller 300 via an electrical signal;
[0059] The second material level meter 420 is electrically connected to the falling material crushing assembly 200;
[0060] The monitoring component includes a first state, a second state, and a third state;
[0061] In the first state, the second material level meter 420 does not detect any material, and the monitoring component controls the crushing roller 300 to increase its rotation speed;
[0062] In the second state, the first material level meter 410 does not detect material, and the second material level meter 420 detects material. At this time, the monitoring component controls the roller conveyor 210 to increase the speed.
[0063] In the third state, the first material level meter 410 detects material, and the monitoring component controls the crushing roller 300 to reduce its rotation speed.
[0064] Specifically, the first material level meter 410 is located close to the crushing roller 300 to maximize the material discharge speed without causing a large amount of material to pile up; the second material level meter is set according to the volume in the buffer discharge assembly, and is generally set in the middle position between the crushing roller 300 and the roller conveyor 210.
[0065] In order to avoid dust caused by falling materials, a downward-inclined guide trough 500 is provided at the lower part of the falling material crushing assembly 200. The inclination direction of the guide trough 500 is the same as the movement direction of the conveyor belt 600. Preferably, the guide trough 500 and the falling material crushing assembly 200 are connected in an articulated manner and fixed by long holes and threads, so that the guide trough 500 can adjust the distance between the guide trough 500 and the conveyor belt 600 according to the parameters of the material (such as the degree of crushing, dryness and wetness, falling material speed, etc.), so as to maximize the avoidance of material spillage and fine powder dusting to pollute the production environment.
[0066] The beneficial effects of this program are analyzed as follows:
[0067] This solution effectively solves various problems caused by materials directly falling onto the conveyor belt 600 during the discharge process of the roller crusher by providing a buffer discharge component 100 and a drop crushing component 200.
[0068] First, the stepped buffer plate 110 in the buffering discharge component 100 can slow down the falling speed of the material, avoid impact on the conveyor belt 600, and thus extend its service life. The roller conveyor 210 in the falling and crushing component 200 further crushes large pieces of material to prevent material blockage and spillage.
[0069] Furthermore, the adjustable distance between the guide trough 500 and the conveyor belt 600 effectively guides materials, reduces fine dust, and improves the production environment. A hydraulic cylinder 220 adjusts the distance between the two roller conveyors 210 to accommodate different materials and optimize drop speed and efficiency. A monitoring component monitors material accumulation in real time and automatically adjusts parameters to prevent blockage.
[0070] Therefore, the device significantly improves the discharge efficiency and equipment reliability, extends the life of the conveyor belt 600, reduces material spillage and dust, and improves the production environment.
[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
