Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a screening and discharge device for a double roll crusher. Background Technology

[0002] When crushing materials, the double roll crusher uses two crushing rolls that rotate in opposite directions to crush the material between the two rolls.

[0003] Currently, double roll crushers cannot guarantee complete crushing in one go when crushing materials, resulting in incompletely crushed materials mixed in. To avoid blockage at the discharge point, screening plates are usually used to intercept and filter large particles. However, existing double roll crushers do not have the function of re-crushing large particles intercepted on the screening plate. As a result, after long-term use, too much material accumulates on the screening plate, affecting the discharge speed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background art by proposing a screening and discharge device for a double roll crusher.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screening and discharge device for a double roll crusher, comprising:

[0007] Crushing and screening tank;

[0008] The feed hopper is fixedly connected to the top of the crushing and screening tank;

[0009] The crushing assembly includes two crushing rollers symmetrically rotatably mounted inside a crushing and screening tank, with the two crushing rollers positioned below the feed hopper. Two gears are rotatably mounted on the surface of the crushing and screening tank, and the two gears mesh with each other and are respectively coaxially fixed to the two crushing rollers. A drive motor for driving one of the crushing rollers to rotate is fixedly mounted on the other side of the crushing and screening tank, and a turntable coaxially fixed to the other crushing roller is also rotatably mounted on the same side of the crushing and screening tank.

[0010] The screening plate is rotatably installed inside the crushing and screening tank and positioned below the two crushing rollers;

[0011] A swing assembly is used to drive the screening plate to reciprocate and rotate.

[0012] Two circulating feeding assemblies are used to feed the material intercepted on the upper surface of the screening plate into the feed hopper, and are respectively installed on both sides of the crushing and screening tank.

[0013] Preferably, the circulating feeding assembly includes a feeding hopper fixedly connected to the side of the crushing and screening tank, the other end of the feeding hopper is inclined downward and fixedly connected to a feeding cylinder, and the feeding cylinder is vertically arranged. The upper end of the side of the feeding cylinder is fixedly connected to a feeding pipe, and the other end of the feeding pipe extends inclinedly into the feeding hopper. A spiral blade is rotatably installed inside the feeding cylinder, and a first bevel gear coaxially fixed to the spiral blade is rotatably installed at the bottom of the feeding cylinder.

[0014] A fixed pipe is fixedly installed inside the crushing and screening tank. A dual-shaft motor is fixedly installed inside the fixed pipe. The two drive ends of the dual-shaft motor are each fixedly installed with a second bevel gear through a rotating shaft. The two second bevel gears mesh with two first bevel gears respectively. Both rotating shafts movably pass through the fixed pipe and the side of the crushing and screening tank.

[0015] Preferably, the oscillating assembly includes a rotating shaft that moves through the center of the crushing and screening tank, and the rotating shaft is fixedly inserted through the center of the screening plate. An oscillating frame is fixedly installed at the end of the rotating shaft. An eccentric shaft is movably connected inside the oscillating frame, and the eccentric shaft is fixedly installed on the side of the turntable away from the crushing and screening tank and off the center of the turntable.

[0016] Preferably, two support plates are symmetrically fixedly installed at the bottom of the crushing and screening tank, and a fixing seat is fixedly installed at the other end of the two support plates.

[0017] Preferably, both ends of the fixed tube extend longitudinally through the surface of the crushing and screening tank.

[0018] Compared with existing technologies, the advantages of the screening and discharge device for a double-roll crusher provided by this utility model are as follows:

[0019] When the crushing roller is rotating and crushing the material, the turntable drives the eccentric shaft to move in a circular motion. By sliding the turntable in the swing frame, the swing frame is moved back and forth to drive the screen plate to rotate reciprocally through the rotating shaft, thereby shaking the material on the screen plate and speeding up the screening speed of the material.

[0020] The dual-shaft motor is started, and driven by the two sets of second bevel gears and the first bevel gear, the two spiral blades rotate synchronously, which transports the material at the bottom of the feeding cylinder from bottom to top, and then feeds it back into the feeding hopper through the feed pipe. It is then crushed again by the two crushing rollers, thereby realizing the cyclic crushing of the material, so as to avoid too much incompletely crushed material accumulating on the screening plate, thereby improving the material discharge speed.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1 to 4 A screening and discharge device for a double-roll crusher, comprising:

[0028] Crushing and screening tank 1; two support plates 19 are symmetrically fixedly installed at the bottom of the crushing and screening tank 1, and the other end of the two support plates 19 is fixedly installed with a fixing seat 20, which plays a supporting and fixing role for the crushing and screening tank 1.

[0029] The feed hopper 2 is fixedly connected to the top of the crushing and screening tank 1; the crushing assembly includes two crushing rollers 3 symmetrically rotatably installed inside the crushing and screening tank 1, with the two crushing rollers 3 positioned below the feed hopper 2. Two gears 4 are rotatably installed on the surface of the crushing and screening tank 1, and the two gears 4 mesh with each other and are respectively coaxially fixed to the two crushing rollers 3. A drive motor 5 for driving one of the crushing rollers 3 to rotate is fixedly installed on the other side of the crushing and screening tank 1, and a turntable 6 coaxially fixed to the other crushing roller 3 is also rotatably installed on the same side of the crushing and screening tank 1. During crushing, the drive motor 5 is started to control the crushing roller 3 fixed to its drive end to rotate. Subsequently, under the transmission of the two gears 4, the other crushing roller 3 rotates in the opposite direction, thereby crushing the material.

[0030] Screening plate 7 is rotatably installed inside crushing and screening tank 1 and positioned below the two crushing rollers 3. Screening plate 7 can intercept large particles of material that are not completely crushed above it.

[0031] The oscillating assembly is used to drive the screening plate 7 to reciprocate and rotate. The oscillating assembly includes a rotating shaft 16 that moves through the center of the crushing and screening tank 1 and is fixedly inserted through the center of the screening plate 7. An oscillating frame 17 is fixedly installed at the end of the rotating shaft 16. An eccentric shaft 18 is movably connected inside the oscillating frame 17 and is fixedly installed on the side of the turntable 6 away from the crushing and screening tank 1 and off the center of the turntable 6. When the other crushing roller 3 rotates, it drives the eccentric shaft 18 to move in a circular motion through the turntable 6. By sliding the eccentric shaft 18 in the oscillating frame 17, the oscillating frame 17 is moved back and forth to drive the screening plate 7 to reciprocate and rotate through the rotating shaft 16, thereby shaking the material on the screening plate 7 and accelerating the screening speed of the material by the screening plate 7.

[0032] Two circulating feeding assemblies are used to feed the material intercepted on the upper surface of the screening plate 7 into the feed hopper 2, and are respectively installed on both sides of the crushing and screening tank 1. The circulating feeding assembly includes a feed hopper 8 fixedly connected to the side of the crushing and screening tank 1. The other end of the feed hopper 8 is inclined downward and fixedly connected to a feed cylinder 9, which is vertically arranged. The upper end of the side of the feed cylinder 9 is fixedly connected to a feed pipe 10, and the other end of the feed pipe 10 extends inclinedly into the feed hopper 2. A spiral blade 11 is rotatably installed inside the feed cylinder 9, and a first bevel gear 12 coaxially fixed to the spiral blade 11 is rotatably installed at the bottom of the feed cylinder 9. A fixed pipe 13 is fixedly installed inside the crushing and screening tank 1, and a dual-shaft motor 14 is fixedly installed inside the fixed pipe 13. The two ends of the fixed pipe 13 extend longitudinally through the surface of the crushing and screening tank 1, allowing the two ends of the fixed pipe 13 to circulate with the outside, so as to facilitate the air convection at both ends to effectively dissipate heat from the dual-shaft motor 14.

[0033] The two drive ends of the dual-shaft motor 14 are each fixedly mounted with a second bevel gear 15 via a rotating shaft, and the two second bevel gears 15 mesh with the two first bevel gears 12 respectively. Both rotating shafts movably pass through the fixed pipe 13 and the side of the crushing and screening tank 1.

[0034] The working principle of this utility model is as follows:

[0035] When in use, first start the drive motor 5, then pour the material to be crushed into the feed hopper 2, so that it slides into the crushing and screening tank 1;

[0036] At this time, the drive motor 5 controls the crushing roller 3 fixed to its drive end to rotate. Then, under the transmission of the two gears 4, the other crushing roller 3 rotates in the opposite direction, which can crush the material. The completely crushed material passes through the screen plate 7 and is discharged through the bottom of the crushing and screening tank 1, while the incompletely crushed material is intercepted above the screen plate 7.

[0037] Next, when the other crushing roller 3 rotates, it drives the eccentric shaft 18 to move in a circular motion through the turntable 6. By sliding within the swing frame 17, it moves the swing frame 17 back and forth to drive the screen plate 7 to rotate reciprocally through the rotating shaft 16, thereby shaking the material on the screen plate 7 and accelerating the screening speed of the material by the screen plate 7. At the same time, when the screen plate 7 swings back and forth, the material on its surface that is not completely crushed will automatically slide into the two feeding hoppers 8 and enter the two feeding cylinders 9.

[0038] Finally, the dual-shaft motor 14 is started. Under the transmission of the two sets of second bevel gears 15 and first bevel gears 16, the two spiral blades 11 are driven to rotate synchronously, conveying the material at the bottom of the feeding cylinder 9 from bottom to top, and then feeding it back into the feeding hopper 2 through the feeding pipe 10. It is then crushed again by the two crushing rollers 3, thereby realizing the cyclic crushing of the material to avoid the accumulation of too much incompletely crushed material on the screening plate 7, thereby improving the material discharge speed.

[0039] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
