Description

Technical Field

[0001] The utility model relates to the technical field related to cracking, in particular to a feed hopper anti-blocking device. Background Art

[0002] Pyrolysis is a reaction process in which a substance decomposes when heated. Many inorganic and organic substances will undergo decomposition reactions when heated to a certain degree. In the past, the pyrolysis process did not involve catalysts, and other energy, such as reactions caused by ultraviolet radiation. At present, in order to improve the efficiency of pyrolysis, increase the yield of pyrolysis products, and prepare products that are not easy to prepare by conventional pyrolysis, more and more research is being done on adding catalysts to the pyrolysis process for catalytic pyrolysis. Some catalytic pyrolysis processes such as adding catalysts such as CaO and MgO to the pyrolysis of plastics have been used in industrial production.

[0003] Before cracking, the cracking material needs to be crushed. For example, when crushing waste tires, the waste tires are placed in a feed hopper containing crushing rollers. However, when multiple waste tires are placed in the feed hopper, the crushing teeth on the crushing rollers have insufficient contact force with the waste tires, resulting in the waste tires being unable to be crushed, causing the feed hopper to be blocked, affecting work efficiency.

Detailed implementation manners

[0025] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0026] The special word "exemplary" here means "serving as an example, embodiment or illustration". Any embodiment described as "exemplary" here does not have to be interpreted as being superior to or better than other embodiments.

[0027] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the gist of the present application.

[0028] The present utility model aims to propose a device for preventing blockage of a feeding hopper, which is applied to the feeding hopper for crushing waste tires before pyrolysis, to eliminate the situation where tires are stacked in the feeding hopper and cannot be fed and crushed. The main purpose is to provide a downward extrusion force for the tires placed in the feeding hopper, so that the tires can be quickly crushed by the crushing rollers. The specific implementation manners are as follows:

[0029] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a feeding hopper anti-blocking device is installed on the feeding hopper 1 and is used to perform an extrusion action when the feeding hopper 1 is blocked; it includes symmetrically arranged movable receiving plates 2, and the movable receiving plates 2 are driven to rotate by a driving member installed on the feeding hopper 1, and when the receiving plates 2 rotate from the vertical state to the horizontal state, they can be connected to a telescopic driving member installed on the feeding hopper 1 and move towards each other or in the opposite direction under the action of the telescopic driving member; it further includes an extrusion unit, and the extrusion unit is installed on the movable receiving plate 2.

[0030] In this embodiment, when the waste tires are normally crushed by the crushing roller in the feed hopper 1, the two movable receiving plates 2 are vertically arranged on both sides of the feed hopper 1 so as not to affect the normal feeding of materials such as tires. When the tires in the feed hopper 1 are blocked, the driving member is started to drive the movable receiving plates 2 to rotate from a vertical position to a horizontal position. Then the movable receiving plates 2 are connected to the telescopic driving member, and the telescopic driving member drives the two movable receiving plates 2 to move toward each other to achieve the blocking of the feed hopper 1. Then, the extrusion unit is used to extrude downward to ensure that no material overflow occurs when the tires and other materials are squeezed. At the same time, the tires and other materials are squeezed toward the crushing roller to achieve rapid crushing and eliminate blockage.

[0031] Furthermore, slide grooves 12 are symmetrically arranged on both sides of the movable supporting plate 2, and a slider 11 is slidably installed in the slide groove 12. The connecting shaft 10 fixed on the slider 11 is rotatably connected to the feed hopper 1 and connected to the driving member. Preferably, the slider 11 is arranged in a "工" shape, and the shape of the slide groove 12 is adapted to the shape of the slider 11.

[0032] As can be seen from the above, since the connecting shaft 10 and the feed hopper 1 are in a rotationally connected state, and the slider 11 is fixed to the connecting shaft 10, the slider 11 will not be displaced relative to the feed hopper 1, so that the movable receiving plate 2 can be driven to rotate when the slider 11 rotates.

[0033] It should be noted that the length of the slide groove 12 is smaller than the length of the movable receiving plate 2 (the length of the movable receiving plate 2 mentioned here refers to a side parallel to the length of the slide groove 12), so as to prevent the slider 11 from being separated from the slide groove 12.

[0034] Furthermore, the driving component includes a motor 4 installed on the feed hopper 1, and the output shaft of the motor 4 is connected to the connecting shaft 10 through a transmission belt 5. When the motor 4 is working, the connecting shaft 10 is driven to rotate by the action of the transmission belt 5. When the connecting shaft 10 rotates, the movable supporting plate 2 is driven to rotate through the action of the slider 11, thereby realizing the driving requirements.

[0035] It should be supplemented that, when the movable supporting plate 2 is in a vertical position, due to the deadweight of the movable supporting plate 2, the movable supporting plate 2 will be in a vertical position.

[0036] See also Figure 1 and Figure 2, the telescopic driving member includes a double-acting cylinder 6 installed on the feed hopper 1. A connecting member 8 is fixed to the end of the piston rod 7 of the double-acting cylinder 6. A convex column 9 is formed on the side of the connecting member 8 facing the feed hopper 1; the convex column 9 is adapted to an arc-shaped groove 13 formed on the movable receiving plate 2, so that when the movable receiving plate 2 rotates to the horizontal placement state, the convex column 9 can move into the arc-shaped groove 13.

[0037] When the movable receiving plate 2 is in the vertical placement state, the piston rod 7 of the double-acting cylinder 6 is at the maximum elongation. When the movable receiving plate 2 rotates from the vertical placement state to the horizontal placement state, the arc-shaped groove 13 provided on the movable receiving plate 2 rotates towards the convex column 9, and finally the convex column 9 is snapped into the arc-shaped groove 13. Subsequently, the piston rod 7 of the double-acting cylinder 6 contracts, which can drive the two movable receiving plates 2 to move towards each other, so that the opposite surfaces of the two movable receiving plates 2 abut against each other to block the feed hopper 1, thus realizing the driving requirement.

[0038] Furthermore, the extrusion unit includes:

[0039] At least one electric telescopic rod 3 installed on the movable receiving plate 2;

[0040] A pressing plate 15 placed in an embedded groove 14 formed on the movable receiving plate 2;

[0041] The movable end of the electric telescopic rod 3 penetrates through the movable receiving plate 2 and is fixed to the pressing plate 15.

[0042] When the two movable receiving plates 2 come into contact, the pressing plate 15 on the movable receiving plate 2 is exactly above the feeding end of the feed hopper 1. Subsequently, the electric telescopic rod 3 extends, which can drive the pressing plate 15 to extrude the materials in the feed hopper 1.
