And the downward movement of the pushing plate can push the impact block to move, hitting the inner wall of the outer shell, performing a dual movement, accelerating the falling of the coal tar on the inner wall of the outer shell, and can comprehensively pre-treat the coal tar during processing, facilitating subsequent processing.

[0017] 2. When the lifting plate below moves up and down, the coal tar pretreatment equipment can scrape the bottom inner wall of the outer shell, preventing the treated coal tar from remaining on it, enabling the comprehensive discharge of coal tar, and the two lifting plates move simultaneously, reducing manual operation and improving work efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a coal tar pretreatment device, including a housing 1, a processing mechanism 2 is arranged on the outer side of the housing 1, both sides of the bottom end of the housing 1 are provided with brackets 3, and the number of the brackets 3 is two, and both brackets 3 are fixedly connected to the housing 1.

[0025] The processing mechanism 2 includes a fixing plate 201, the fixing plate 201 is located at the top of the housing 1 and is fixedly connected to the housing 1. A motor 202 is arranged below the fixing plate 201, the end of the output shaft of the motor 202 is provided with a threaded rod 203, and a circular plate 204 is arranged at the bottom end of the fixing plate 201. A pushing plate 205 is arranged on the inner wall of the circular plate 204, the inner wall of the pushing plate 205 is arc-shaped. An impact block 206 is arranged at the bottom end of the fixing plate 201. A lifting plate 207 is arranged on one side of the threaded rod 203. The cross-sectional shapes of the circular plate 204, the lifting plate 207 and the pushing plate 205 are all "mouth" shaped. The number of the lifting plates 207 is two, and the two lifting plates 207 are arranged vertically and collinearly. A steel wire rope 208 is fixedly arranged at the top end of the top lifting plate 207.

[0026] The threaded rod 203 passes through the circular plate 204 and is threadedly connected to the circular plate 204. A round block 209 is fixedly arranged on the side of the impact block 206 away from the housing 1.

[0027] A vertical rod 210 is arranged between the two lifting plates 207. A filter screen 211 is fixedly arranged on the inner wall of the housing 1. The vertical rod 210 passes through the filter screen 211 and is movably connected to the filter screen 211. A lead ball 212 is arranged inside the vertical rod 210, and the number of the lead balls 212 is multiple.

[0028] Sealing plates 213 are arranged on both the bottom inner wall and the top inner wall of the housing 1. The sealing plates 213 are fixedly connected to the housing 1 by screws. A guiding rod 214 is arranged on the top of the bracket 3. The guiding rod 214 passes through the circular plate 204 and is movably connected to the circular plate 204.

[0029] A groove 215 is arranged on the inner wall of the housing 1. One end of the impact block 206 extends into the groove 215. A spring 216 is arranged inside the groove 215, and the spring 216 is in contact with the impact block 206. The spring 216 is arranged around the outer surface of the impact block 206.

[0030] During operation, first remove the upper sealing plate 213, open the top end of the outer shell 1, and then place the coal tar inside the outer shell 1. Filter the coal tar through the filter screen 211 in the outer shell 1. During the filtering process, use the motor 202. Since the end of the output shaft of the motor 202 is in transmission connection with the threaded rod 203, the rotation of the motor 202 drives the threaded rod 203 to rotate. During the rotation of the threaded rod 203, the annular plate 204 threadedly connected to the threaded rod 203 moves downward at the same time. Because the annular plate 204 is movably connected to the guide rod 214, the annular plate 204 moves downward along the guide rod 214. The annular plate 204 is fixedly connected to the steel wire rope 208 and the push plate 205 respectively, so that the bottom end of the steel wire rope 208 and the push plate 205 move downward at the same time, improving the work efficiency. When the steel wire rope 208 moves downward, the lifting plate 207 fixedly connected to the steel wire rope 208 moves upward. During the upward movement of the lifting plate 207, because the lifting plate 207 contacts the inner wall of the outer shell 1, the inner wall of the outer shell 1 is scraped, reducing the coal tar remaining inside the outer shell 1. And the two lifting plates 207 are fixedly connected by the vertical rod 210. When the upper lifting plate 207 moves upward, the lower vertical rod 210 and the lifting plate 207 move upward at the same time. Through the upward movement of the lower lifting plate 207, the inner wall of the bottom end of the outer shell 1 is scraped, and all the materials can be pretreated. Since the vertical rod 210 is movably connected to the filter screen 211, the upward movement of the vertical rod 210 is ensured. When the push plate 205 moves downward, it can contact the round block 209. Through the continuous downward movement of the push plate 205, the round block 209 is pushed to move towards the outer shell 1, and the impact block 206 fixedly connected to the round block 209 enters the outer shell 1. The cross-sectional shape of the impact block 206 is cross-shaped, and the spring 216 is arranged around the outer surface of the impact block 206 and is squeezed by the spring 216 in the groove 215. Through the movement of the impact block 206, the inner wall of the outer shell 1 can be impacted, accelerating the falling of the coal tar on the surface of the outer shell 1. And when the push plate 205 moves upward, the setting of the steel wire rope 208 will not affect the upward movement of the push plate 205.

[0031] At the same time, the content not described in detail in this specification belongs to the prior art well known to those skilled in the art.
