Description

TECHNICAL FIELD

[0001] The utility model relates to cement grinding equipment technical field, specifically a ball mill feed chamber inner circle automatic material cleaning device. BACKGROUND

[0002] Ball mill is important grinding equipment in cement grinding field, and the main working part is rotary cylinder, and the material is crushed and ground by the impact and grinding action of the steel ball, steel segment and other grinding medium (or grinding body) loaded in the cylinder. The material enters the feed chamber through the mill inlet chute, and then the material is guided into the ball mill through the feed chamber. In order to improve the grinding efficiency, liquid grinding aid is usually added from the ball mill feed port, but due to the excessive addition of grinding aid or excessive water, the material coagulation ring is formed near the inner circle of the mill head side of the feed chamber, which seriously causes the material to be reversed, and affects the normal operation of the mill.

[0003] The existing technology is to enter the machine warehouse inside by using the opportunity of shutdown, and the coagulation ring is cleaned manually, which is time-consuming and laborious, the operation environment is poor, there are more dust, and there are various safety risks such as mechanical injury and object strike. INVENTION CONTENTS

[0004] The utility model aims at solving the above problems, and provides a ball mill feed chamber inner circle automatic material cleaning device which does not need to stop cleaning.

[0005] The utility model solves the problem, and the technical scheme adopted is:

[0006] A ball mill feed chamber inner circle automatic material cleaning device, which comprises a support rod located in the feed chamber and fixed at one end on the mill inlet chute shell, the other end of the support rod extends to the mill head side and is inclined upward, a scraping mechanism is connected to the other end of the support rod, and the scraping mechanism is in gap with the top of the inner circle of the feed chamber.

[0007] The utility model adopting the above technical scheme has the prominent characteristics compared with the prior art:

[0008] The scraping mechanism utilizes the self-rotation of the ball mill to automatically clean the sticky material on the inner circle of the feed chamber, effectively avoids the coagulation shutdown accident, and improves the equipment operation efficiency.

[0009] As a preferred embodiment, the further technical scheme of the utility model is:

[0010] Further, the scraping mechanism comprises a T-shaped scraper, the horizontal section of the scraper is in gap cooperation with the top of the inner circle of the feed chamber, and the vertical section of the scraper is fixed to the end of the support rod away from the mill inlet chute.

[0011] Further, a reinforcing rib is arranged between the bottom of the end of the support rod away from the mill inlet chute and the bottom end of the vertical section of the scraper. DRAWINGS

[0012] Figure 1 Structure schematic view of the embodiment of the present application;

[0013] In the figure, the marks are: the inlet chute 1, the feeding cavity 2, the support rod 3, the scraper 4, and the reinforcing rib 5. DETAILED DESCRIPTION

[0014] The present application will be further described in connection with the embodiments, and the purpose is only to better understand the content of the present application, therefore, the examples do not limit the protection scope of the present application.

[0015] The automatic material cleaning device in the inner ring of the feeding cavity of the ball mill feeding cavity comprises a support rod 3 located in the feeding cavity 2 and fixed at one end of the inlet chute 1 shell, the other end of the support rod 3 extends to the mill head side and is inclined upward, a material scraping mechanism is connected to the other end of the support rod 3, the material scraping mechanism is matched with the inner ring top of the feeding cavity 2, and the support rod 3 is inclined to prevent interference to the feeding.

[0016] Further, the material scraping mechanism comprises a T-shaped scraper 4, the horizontal section top of the scraper 4 is matched with the inner ring top of the feeding cavity 2, when the ring is formed, the horizontal section of the scraper 4 is automatically cleaned on the ring by the self-rotation of the ball mill, the vertical section middle of the scraper 4 is fixed to the end of the support rod 3 away from the inlet chute 1, the scraper 4 is made of channel steel, the horizontal section and the vertical section of the scraper 4 are fixed by welding, and the horizontal section of the scraper 4 cleans the sticky material when the feeding cavity 2 rotates.

[0017] Further, the reinforcing rib 5 is arranged between the bottom of the end of the support rod 3 away from the inlet chute 1 and the vertical section bottom end of the scraper 4, the reinforcing rib 5 is made of channel steel, the two ends of the reinforcing rib 5 are fixed by welding between the scraper 4 and the support rod 3, and the stability is ensured through the reinforcing rib 5.

[0018] The device does not need to provide additional power, utilizes the self-rotation of the ball mill to realize automatic cleaning of the sticky material, does not need to open the equipment maintenance door to enter the inside of the equipment to clean the sticky material, avoids dangerous operations such as limited space and high-altitude operation, completely eliminates many safety risks such as high-altitude falling, oxygen suffocation, high-temperature heat stroke, burial, silicosis and the like, effectively avoids environmental pollution caused by dust overflow, is not limited to cleaning the sticky material in the shutdown state, avoids that the sticky material is attached and solidified for a long time to form a sticky material that is difficult to clean, and reduces the labor intensity of the post personnel.

[0019] The above only describes the preferred and feasible embodiments of the present application, and is not limited to the scope of the present application, and equivalent changes made by applying the content of the present application and the drawings are included in the scope of the present application.
