A feed inlet anti-clogging hammer crusher

Abstract

This utility model discloses a feed inlet anti-clogging hammer crusher, including a hammer crusher body, a feed inlet, a screen plate assembly, a drive device, and a control device. The hammer crusher body is fixedly installed, and the feed inlet is installed above the hammer crusher body. Screen plate assemblies are respectively installed on opposite side walls inside the feed inlet. The screen plate assemblies can swing relative to the side walls. The drive device is connected to the screen plate assembly and is used to drive the screen plate assembly to swing.

When there are many large materials or the material level is high, the screen plate spacing can be increased in time to provide a spacious feeding space for the material, fundamentally preventing material from clogging in the feed inlet and ensuring the long-term stable operation of the crusher.

Description

Technical fields:

[0001] This utility model relates to the field of feed inlet anti-blocking technology, specifically to a feed inlet anti-blocking hammer crusher. Background technology:

[0002] Hammer crushers are widely used in the crushing and processing of materials such as coal and ore due to their high crushing capacity. However, in actual operation, the feed inlet of hammer crushers often faces the problem of blockage. On the one hand, when there are large-sized material blocks in the feed, these blocks can easily get stuck in the narrow part of the feed inlet, hindering the normal conveying of subsequent materials. On the other hand, if the feed speed is not matched with the crushing speed, the material in the feed inlet will accumulate too high, which will also cause blockage. The feed inlet structure of traditional hammer crushers is usually fixed and lacks the function of dynamic adjustment according to the actual feeding situation (such as the distribution of material block size, material level, etc.). Once blockage occurs, it will not only reduce the working efficiency of the crusher and increase the energy consumption of the equipment, but may also cause equipment overload damage due to prolonged blockage, significantly increasing maintenance costs and downtime, seriously affecting the continuity of production and the economic benefits of enterprises. Utility Model Content:

[0003] Therefore, this utility model provides a feed inlet anti-clogging hammer crusher to overcome the problems of the prior art.

The control device is connected to the drive device and a detection component inside the feed inlet, respectively, and is used to control the drive device to operate according to the detection signal of the detection component, thereby adjusting the angle between the screen plate assemblies and the side walls and changing the distance between the two screen plate assemblies.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 , Figure 2 As shown, a feed inlet anti-clogging hammer crusher mainly consists of a hammer crusher body 1, a feed inlet 2, a screen plate assembly, a drive device, and a control device. The hammer crusher body 1 is fixedly installed on a support frame and is the core crushing component of the crusher. The feed inlet 2 is installed above the hammer crusher body 1 and is used for material input.

[0017] The screen plate assembly includes a screen plate 3 and a swing plate 5. The screen plate 3 is fixedly installed on the swing plate 5. The swing plate 5 is hinged to the opposite side wall inside the feed inlet 2 via a hinge shaft. This hinge method allows the swing plate 5 to swing freely around the hinge shaft, thereby driving the screen plate 3 to change its angle and realize the adjustment of the size of the feed channel.

[0018] The driving device includes a push plate 6 and an electric push rod 7. One end of the push plate 6 is fitted with the swing plate 5, and the contact end between the push plate 6 and the swing plate 5 is spherically shaped to reduce friction during the pushing process and ensure that the push plate 6 can stably apply force to the swing plate 5 regardless of the angle of the screen plate 3. The other end of the push plate 6 extends out of the feed inlet 2 and is fixedly connected to the output end of the electric push rod 7. The electric push rod 7 is fixedly mounted on the outside of the feed inlet 2 by a positioning frame 8. When the electric push rod 7 is started, its output end pushes the push plate 6, and the push plate 6 pushes the swing plate 5 to rotate around the hinge axis, thereby causing the screen plate 3 to swing.

[0019] The control device includes a controller 9. A level gauge 4 is fixedly installed on the inner wall of the feed inlet 2 and at the lower end of the screen plate assembly. In this embodiment, the level gauge 4 is a radar level gauge. The level gauge 4 is electrically connected to the controller 9 to transmit the real-time measured level data in the feed inlet 2 to the controller 9. The electric push rod 7 is electrically connected to the controller 9. The controller 9 controls the action of the electric push rod 7 according to the level information transmitted by the level gauge 4 and the preset program to realize the automatic adjustment of the angle of the screen plate 3.

[0020] Actual work process:

[0021] In the initial state, the screen plate 3 is at a certain angle, and the two screen plates 3 maintain a suitable distance so that the material can enter the hammer crusher body 1 normally from the feed inlet 2 for crushing. At this time, the radar level gauge 4 installed on the inner side wall of the feed inlet 2 and located at the lower end of the screen plate 3 monitors the material level in the feed inlet in real time.

[0022] When the proportion of large coal pieces in the feed increases, or when the material accumulates in the feed inlet 2, causing the material level to gradually rise and approach the preset high value, the radar level gauge 4 will transmit the detected signal to the controller 9.

[0023] After receiving the signal from the level gauge 4, the controller 9 makes a judgment based on the internally preset program. If it is determined that the angle of the screen plate 3 needs to be adjusted to increase the feeding space and prevent blockage, the controller 9 issues a command to control the electric push rod 7 to start.

[0024] The output end of the electric push rod 7 pushes the push plate 6. Since the contact end between the push plate 6 and the swing plate 5 is spherical, the push plate 6 can smoothly push the swing plate 5 to rotate around the hinge axis, thereby causing the screen plate 3 to swing and increasing the distance between the two screen plates 3. At this time, large coal pieces can enter the crusher body 1 more smoothly through the feed inlet 2, effectively avoiding blockage at the feed inlet 2.

[0025] As the crushing operation proceeds, when the material level drops to a suitable range, or when the proportion of large coal pieces decreases, the level gauge 4 transmits the signal to the controller 9 again. The controller 9 controls the electric push rod 7 to reverse its movement, so that the screen plate 3 returns to a suitable angle, maintaining effective control over the feed particle size and ensuring the continuous and stable operation of the crusher.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
