Description

Technical Field

[0001] The utility model relates to the technical field of coal screening, and particularly relates to a vibrating coal screening machine. Background Art

[0002] In the coal mining and processing industries, as the core equipment for coal grading, the performance of vibrating coal screening machines directly affects the quality and production efficiency of coal products. In the design of traditional vibrating coal screening machines, an inclined screen structure is generally adopted. This design concept is mainly based on the principle of natural sliding under the action of gravity, that is, coal materials slide along the inclined screen surface due to gravity, and at the same time, under the vibration of the screen, particle separation is achieved. However, with the development of the coal industry and the continuous improvement of the quality requirements for coal products, the following significant limitations have gradually emerged in this traditional design;

[0003] Although the inclined screen can accelerate the flow of coal materials by using gravity, in the actual screening process, the particle size distribution of coal materials is often complex and diverse. Due to their small own mass, fine particles have a very short residence time on the screen and are difficult to fully contact the screen holes, resulting in a large amount of fine coal materials not passing through the screen holes in time and being carried out by large particle coal materials, thus reducing the overall screening efficiency and accuracy. This not only increases the burden of subsequent processing procedures but also affects the final quality of coal products. Therefore, we make improvements on this and propose a vibrating coal screening machine. Summary of the Invention

[0032] As recorded in the background art, although the inclined screen can utilize gravity to accelerate the flow of coal material, in the actual screening process, the particle size distribution of coal material is often complex and diverse. Due to their small own mass, fine particles have a very short residence time on the screen and are difficult to fully contact the screen holes, resulting in a large amount of fine coal material not passing through the screen holes in time and being carried out by the large particle coal material, thus reducing the overall screening efficiency and accuracy. This not only increases the burden of subsequent processing procedures but also affects the final quality of coal products.

[0033] To solve this technical problem, the present utility model provides a vibrating screening coal machine, which is applied to the screening of coal material.

[0034] Specifically, please refer to Figures 1-4 , the vibrating screening coal machine specifically includes:

The driving part is used to drive the first support frame 1 to rotate to realize the adjustment of the vibrating screening part.

[0036] For the vibrating screening coal machine provided by the present utility model, in the present application, the adjusting part can drive the first support frame 1 to rotate, and then realize the adjustment of the vibrating screening part, and can adjust the inclination direction of the vibrating screening part, so that the coal material to be screened can reciprocate between both ends of the vibrating screening part, and then the coal material can be more fully dispersed and contacted on the vibrating screening part, and the fine particles can more effectively pass through the screen holes, significantly improving the screening efficiency and accuracy.

[0037] To enable those skilled in the art to better understand the solution of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings.

[0038] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0039] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0040] For Embodiment 1, please refer to Figures 1-4 , a vibrating screening coal machine, including a first support frame 1 and a bottom frame 3 arranged below the first support frame 1. A vibrating screening part is arranged on the first support frame 1. Adjusting parts are arranged between both sides of the first support frame 1 and the bottom frame 3. The adjusting part includes a bearing shaft 102 installed on the side surface of the first support frame 1. A bearing seat 101 is sleeved on the outer surface of the bearing shaft 102 through a bearing. The bearing seat 101 is fixedly connected to the bottom frame 3, and a driving part is arranged between the bearing seat 101 and the first support frame 1. The driving part is used to drive the first support frame 1 to rotate to realize the adjustment of the vibrating screening part. Through the adjusting part of the present application, the first support frame 1 can be driven to rotate, and then the adjustment of the vibrating screening part can be realized. The inclination direction of the vibrating screening part can be adjusted, so that the coal material to be screened can reciprocate between both ends of the vibrating screening part, and then the coal material can be more fully dispersed and contacted on the vibrating screening part, and fine particles can pass through the sieve holes more effectively, significantly improving the screening efficiency and accuracy.

[0041] Furthermore, as Figures 1-4 shown, the driving part includes a reduction motor 104 installed on the bearing seat 101 and an arc-shaped rack 103 installed on the first support frame 1. The output shaft of the reduction motor 104 is fixedly connected with a gear 105. The gear 105 meshes with the arc-shaped rack 103. The reduction motor 104 can drive the arc-shaped rack 103 to rotate through the gear 105, and then the angle of the first support frame 1 can be adjusted, so that the inclination direction of the first support frame 1 and the vibrating screening part is changed.

[0042] Furthermore, as Figures 1-4 shown, two cylinders 4 are further installed on the top of the bottom frame 3. The tops of the cylinders 4 correspond to the bottom of the first support frame 1. During transportation, the first support frame 1 is supported and limited by the cylinders 4, which can prevent the first support frame 1 from rotating during transportation and affecting the transportation.

[0043] For Embodiment 2, the vibrating screening coal machine provided in Embodiment 1 is further optimized. Specifically, the vibrating screening part includes a second support frame 2 located above the first support frame 1. A plurality of elastic parts are arranged between the second support frame 2 and the first support frame 1. The arrangement of the elastic parts enables the second support frame 2 to vibrate, so as to facilitate the screening of coal material.

[0044] Furthermore, as Figures 1-4As shown in the figure, the elastic member includes a spring 203 installed on the first support frame 1. The spring 203 is connected to a connecting seat 202, and the connecting seat 202 is fixedly connected to the side surface of the second support frame 2. The setting of the spring 203 can facilitate the vibration of the second support frame 2.

[0045] Furthermore, as Figures 1-4 shown in the figure, a vibration motor 204 is installed on the side surface of the second support frame 2. The setting of the vibration motor 204 can drive the second support frame 2 to vibrate, so as to facilitate the screening of coal materials.

[0046] In Embodiment 3, the vibrating screening coal machine provided in Embodiment 1 or 2 is further optimized. Specifically, as Figure 2 、 Figure 5 and Figure 6 shown in the figure, a screen main body 201 is fixedly installed inside the second support frame 2. A discharge port 205 is provided on one side of the first support frame 1. A blocking plate 206 for blocking the discharge port 205 is installed on the outside of the second support frame 2 through a hinge. The blocking of the discharge port 205 by the blocking plate 206 enables the pulverized coal not to be discharged temporarily during the reciprocating tilting process of the second support frame 2, so as to ensure the screening of the pulverized coal.

[0047] Furthermore, as Figure 6 shown in the figure, buckles 207 are installed between both sides of the blocking plate 206 and the second support frame 2. The buckles 207 are used for limiting the position of the blocking plate 206.

[0048] Furthermore, as Figure 5 shown in the figure, a second discharge port 209 is fixedly installed at the bottom of the second support frame 2. The second discharge port 209 is used for the centralized discharge of the fine materials after screening.

[0049] Furthermore, as Figure 4 and Figure 5 shown in the figure, a first discharge hopper 208 is fixedly installed on one side of the second support frame 2. The position of the first discharge hopper 208 corresponds to the position of the discharge port 205. The first discharge hopper 208 is used for the centralized discharge of the coarse materials after screening.

[0050] The usage process of the vibrating screening coal machine provided by the present utility model is as follows:

[0051] The piston rod of the air cylinder 4 descends, and the reduction motor 104 drives the first support frame 1 to rotate through the gear 105 and the arc-shaped rack 103, so that the first support frame 1 and the second support frame 2 tilt towards one direction, pour pulverized coal onto the screen body 201, and then the vibration motor 204 drives the second support frame 2 to vibrate to screen the pulverized coal. During the screening process, the reduction motor 104 drives the first support frame 1 to rotate through the gear 105 and the arc-shaped rack 103, so that the first support frame 1 and the second support frame 2 tilt towards the other direction, tilt back and forth like this, and finally tilt towards the discharge port 205, so that the pulverized coal moves towards the discharge port 205. After opening the plugging plate 206, the coarse pulverized coal is discharged from the discharge port 205 to the first discharge hopper 208, and then discharged from the first discharge hopper 208.
