Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement production technology, specifically to a grate device for cement production. Background Technology
[0002] Cement, also known as cement, is a powdery hydraulic inorganic binder that hardens when mixed with water. It is usually not used alone but rather combined with sand and gravel (aggregates) to form mortar or concrete. The main raw material of cement is lime or calcium silicate. After hardening, it can resist the erosion of fresh water or salt water. As an important binder, it is widely used in civil engineering, water conservancy, national defense and other projects. Cement is an important basic construction material. It is not only widely used in industrial and civil buildings, but also in transportation, water conservancy, agriculture and forestry and seaport projects. The cement industry has broad prospects.
[0003] In the actual production and processing of cement, after grinding, the cement powder needs to be transported to the dry powder silo via pipelines. However, during this process, impurities and filter cloths often get mixed in. Existing grate devices have fixed filter holes that cannot be adjusted. Due to the stickiness of cement, the grate is easily clogged, making cleaning difficult. This causes impurities and filter cloths to easily jam the conveying device during transport, increasing the workload of maintenance workers and affecting normal, continuous, and stable production. Therefore, this utility model proposes a grate device for cement production to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a grate plate device for cement production, so as to solve the problem mentioned in the background art that the fixed size of the grate plate filter holes and the inability to remove debris cause the device to jam.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a grate device for cement production, comprising: a tank body, the inner wall of which is connected to a rotating ring, a first grate plate, and a second grate plate. The second grate plate is identical to the first grate plate and is rotatably connected to it. An arc-shaped plate is engaged with the rotating ring. A claw hook is fixedly connected to one end of the surface of the arc-shaped plate. A threaded rod is connected to the arc-shaped plate through a connecting pipe. The lower end of the arc-shaped plate contacts the upper surface of the first grate plate.
[0006] Preferably, the inner wall of the tank is fixedly connected to the first grate, the inner wall of the tank is rotatably connected to the second grate, the rotating ring is rotatably connected to the inner wall of the tank, a motor is fixedly connected to the upper end of the inner wall of the tank, an inlet is opened at the upper end of the tank, and an outlet is opened at the lower end.

[0017] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a grate device for cement production, comprising: a tank body 1, with an inlet at the upper end and an outlet at the lower end. Material enters the tank body 1 through the inlet, passes through the device, and then enters a transportation channel through the outlet. The inner wall of the tank body 1 is fixedly connected to a first grate 14, and a rotating ring 2 is rotatably connected to the inner wall of the tank body 1. This allows for the overall fixation and positioning of the components inside the tank body 1, preventing shaking and displacement. A motor 4 is fixedly connected to the upper end of the inner wall of the tank body 1, serving as the overall power source. The inner wall of the tank body 1 and the first grate 14 are both rotatably connected to a second grate 15. The rotation of the second grate 15 allows for the adjustment of the size of the filter holes between the first grate 14 and the second grate 15.
[0019] A fixed post 6 is fixedly connected to the output end of the motor 4, and a threaded rod 9 is fixedly connected to the other end of the fixed post 6. When the motor 4 starts, both the fixed post 6 and the threaded rod 9 will start to rotate. The lower end of the threaded rod 9 is rotatably connected to the first grate plate 14, making its rotation smoother. A rotating groove is opened on the surface of the fixed post 6, and an abutment block 7 is rotatably connected to the inner wall of the rotating groove. The size and shape of the abutment block 7 match the rotating groove. A spring 8 is fixedly connected to the inner ring surface of the abutment block 7. The spring 8 can make the abutment block 7 quickly return to its original position. The other end of the spring 8 is fixedly connected to the fixed post 6. The outer arc surface and side surface of the abutment block 7 are in contact with the pipe cover 5. When the fixed post 6 drives the abutment block 7 to rotate in the direction of the end rotatably connected to the fixed post 6, the abutment block 7 will be squeezed by the pipe cover 5, which will then compress the spring 8 and close into the rotating groove. When the fixed post 6 drives the abutment block 7 to rotate away from the end rotatably connected to the fixed post 6, the fixed post 6 forces the pipe cover 5 to rotate synchronously under the action of the abutment block 7.
[0020] The end of the arc-shaped plate 12 away from the claw hook 13 is fixedly connected to the connecting pipe 10. The surface of the threaded rod 9 is threadedly connected to the connecting pipe 10. Three guide plates 11 are slidably connected to the surface of the connecting pipe 10. The guide plates 11 can provide vertical guidance and horizontal limiting for the connecting pipe 10. The lower end of the guide plate 11 is rotatably connected to the upper surface of the first grate plate 14. The other end of the guide plate 11 is slidably connected to the pipe cover 5. When the pipe cover 5 starts to rotate, it can drive the guide plate 11 to start rotating. The rotation of the guide plate 11 can drive the connecting pipe 10 to rotate, which in turn drives the arc-shaped plate 12 to rotate. The outer wall of the pipe cover 5 is rotatably connected to the handle 3. The midpoint of the handle 3 is located above the tank body 1. The forward rotation direction of the motor 4 is clockwise. There are three arc-shaped plates 12, and the outer arc surface is bent clockwise.
[0021] When this device is in operation, after verifying that the device is working correctly, rotating the second grate 15 can adjust the overlap of the filter holes between the first grate 14 and the second grate 15, thereby adjusting the size of the filter holes. Then, start the motor 4. When the motor 4 starts rotating forward, it will drive the tube cover 5 to rotate through the abutment block 7, which in turn drives the arc plate 12 to rotate towards the outer arc surface. The centrifugal force provided by the rotation forces the filter cloth and other debris to move towards the claw hook 13. At this time, the claw hook 13, the threaded rod 9, and the tube cover 5 are relatively stationary. After filtration is completed, it is necessary to remove the debris from the claw hook 13. At this time, start the motor 4 to rotate in the reverse direction, so that the abutment block 7 is engaged in the rotating groove. Then, by lifting the handle 3, the tube cover 5 is moved upward. At this time, the tube cover 5 is slidably connected to the guide plate 11, so that the guide plate 11 stops rotating. At the same time, the threaded rod 9 continues to rotate, so that the connecting pipe 10 moves upward under your action, which makes it easier to clean the claw hook 13. The device as a whole can effectively clean the filter cloth and other debris, thereby avoiding the situation where the machine is jammed.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
