Description

Technical Field

[0001] The utility model relates to the technical field of catalyst processing, in particular to a catalyst raw material vibrating screen. Background Art

[0002] A catalyst, also known as a catalyst, is a substance that changes the reaction rate but does not change the total standard Gibbs free energy of the reaction. In the process of producing and processing catalysts, a vibrating screen is usually required to screen the catalyst raw materials.

[0003] The patent with publication number CN220611257U in the prior art discloses a vibrating screen for catalyst processing with a material guiding structure. It is used by setting horizontal guide plates on both sides of the screen frame in conjunction with a rotating mechanism composed of a rotating rod, gears, U-shaped plates, tooth blocks and screws. The horizontal guide plates can be controlled to rotate on the surface of the screen during use. The horizontal guide plates staggered on both sides can guide the raw materials to ensure the screening effect. However, during use, if the staff accidentally pours too much raw material at one time, it will easily accumulate raw materials and cause incomplete screening. The screening effect is not ideal and needs further improvement. Therefore, in order to solve the above problems, the present application proposes a catalyst raw material vibrating screen. Utility Model Content

[0008] The elastic return element comprises a return tension spring sleeved on the horizontal insertion rod, and two ends of the return tension spring are respectively fixedly mounted on the fixing protrusion and the side of the handle block.

[0009] Four supporting legs are fixedly installed on the bottom of the screening box, and moving wheels are fixedly arranged at the bottom ends of the four supporting legs.

[0011] An observation hole is provided on the side of the screening box body, and an observation window is fixedly arranged in the observation hole.

[0012] In summary, the technical effects and advantages of the utility model are:

[0013] 1. The utility model has a reasonable structure. When the control knob is turned, the adjusting plate will be driven to rotate together through the control rod, the transmission worm, the transmission worm wheel and the support rod, thereby achieving the purpose of adjusting the falling speed of the raw materials, thereby effectively reducing the situation where the raw materials are easily piled up due to careless pouring of too much raw materials at one time, resulting in incomplete screening, improving the screening effect of the device, and can be adapted and adjusted for different types of raw materials. It has a wide range of applications, simple operation, convenient use and good practicality.

[0014] 2. In the utility model, when the handle block is pulled, the horizontal rod is driven to move out of the fixed insertion hole, and the control knob is loosened. When the handle block is loosened, the horizontal rod is driven to automatically reset and insert into the fixed insertion hole under the elastic force of the reset tension spring, and the control knob is always fixed. Therefore, during use, the situation that the speed of raw material falling changes due to the self-rotation of the control knob caused by the vibration of the device can be effectively reduced, and the stability is good during use;

[0015] 3. In the utility model, when the control dial is rotated, the contact plate will be driven to move up and down through the vertical studs and vertical screw holes. When the contact plate is moved upward to leave the ground, the device can be directly pushed to move through the moving wheels. When the contact plate is moved downward to contact the ground, the friction between the device and the ground can be effectively increased, and the device can be stably placed on the ground for use, which is more practical.

Control rotating rods 8 are installed in the two mounting rotating holes for common rotation. A control knob 9 is fixedly installed on the top of the control rotating rod 8. A synchronous transmission unit for making the supporting rotating rod 5 rotate synchronously is connected to the control rotating rod 8. The synchronous transmission unit includes a transmission worm 10 fixedly sleeved on the control rotating rod 8, and a transmission worm wheel 11 meshing with the transmission worm 10 is fixedly installed on one end of the supporting rotating rod 5. A fixing unit for fixing the control knob 9 is provided on the feed hopper 4.

[0022] By means of the above structure, when the control knob 9 is rotated, the control rotating rod 8 and the transmission worm 10 will be driven to rotate. The rotation of the transmission worm 10 will drive the supporting rotating rod 5 to rotate synchronously through the transmission worm gear 11, and then drive the adjusting rotating plate 6 to rotate together, thereby achieving the purpose of adjusting the falling speed of the raw materials, thereby effectively reducing the situation where the raw materials are easily accumulated due to accidentally pouring too much raw materials at one time, resulting in incomplete screening, improving the screening effect of the device, and can be adapted and adjusted for different types of raw materials, with a wide range of applications, simple operation, easy use, and good practicality.

[0023] As a preferred implementation of this embodiment, the fixing unit includes a fixing protrusion 12 fixedly mounted on the side of the feed hopper 4, a horizontal sliding hole is provided on the side of the fixing protrusion 12, a horizontal plug rod 13 is slidably mounted in the horizontal sliding hole, a plurality of fixing sockets are evenly provided on the circumferential side of the control knob 9, one end of the horizontal plug rod 13 extends into one of the fixing sockets, a handle block 14 is fixedly mounted on the other end of the horizontal plug rod 13, and an elastic return element is mounted on the handle block 14. The advantage of such a setting is that when the handle block 14 is moved left and right, the horizontal plug rod 13 will be driven to move in or out of the fixing socket, thereby fixing or loosening the control knob 9, thereby effectively reducing the situation in which the falling speed of the raw materials changes due to the rotation of the control knob 9 caused by the vibration of the device during use, and the stability is good during use.

[0024] In this embodiment, the elastic return element includes a reset spring 15 sleeved on the horizontal insertion rod 13, and the two ends of the reset spring 15 are respectively fixedly mounted on the fixed protrusion 12 and the side of the handle block 14. The advantage of this arrangement is that when the handle block 14 is released, the handle block 14 will be automatically reset under the elastic force of the reset spring 15, and then the horizontal insertion rod 13 can be automatically inserted into the fixed insertion hole, so that the control knob 9 is always fixed, which is stable and reliable.

[0025] As a preferred implementation manner of this embodiment, four supporting legs 16 are fixedly installed at the bottom of the screening box 1, and moving wheels 17 are fixedly installed at the bottom ends of the four supporting legs 16.

A control turntable 20 is fixedly installed at the top of the two vertical studs 19, and a resistance plate 21 is fixedly installed at the bottom ends of the two vertical studs 19. The advantage of such a configuration is that when the control dial 20 is rotated, the vertical stud 19 will be driven to rotate together. At this time, under the action of the vertical screw hole, the vertical stud 19 will move up and down while rotating, thereby driving the contact plate 21 to move up and down together. When the contact plate 21 is moved upward to leave the ground, the device can be directly pushed to move by the moving wheel 17. When the contact plate 21 is moved downward to contact the ground, the friction between the device and the ground can be effectively increased, and the device can be stably placed on the ground for use, which is more practical.

[0026] As a preferred implementation of this embodiment, an observation hole is opened on the side of the screening box 1, and an observation window 22 is fixed in the observation hole. The advantage of this arrangement is that the staff can directly observe the real-time working conditions in the screening box 1 through the observation window 22.
