Detailed Implementation
[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on 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.
[0020] The following is combined with Figure 1-5The specific embodiments of this utility model are further described in detail: A device for processing hard solid waste in a laboratory includes an upper cover 1, an upper grinding disc 2, an outer shell 3, a lower grinding disc 4, a reduction motor 6, and a spring 10. The outer shell 3 is a round tube, and the upper end face of the outer shell 3 is connected to the upper cover 1 by a fixing bolt 9. A through hole A is provided at the center of the upper end face of the upper cover 1. A base 5 is provided on the lower end face of the outer shell 3, and a mounting hole 51 is provided at the edge of the base 5. The mounting hole 51 is used to install this device on a workbench.
[0021] The upper grinding disc 2 is fitted into the inner hole of the outer shell 3. The lower end of the upper grinding disc 2 is an inclined disc, and the side wall of the disc contacts the inner hole wall of the outer shell 3. The upper end of the upper grinding disc 2 is a cylinder, and a spring 10 is fitted on the cylinder. The upper end of the cylinder passes through the through hole A of the upper cover 1. The inner diameter of the through hole A is adapted to the outer diameter of the cylinder at the upper end of the upper grinding disc 2. The cylinder at the upper end of the upper grinding disc 2 can slide up and down through the through hole A. The spring 10 is engaged between the upper end face of the disc of the upper grinding disc 2 and the lower end face of the upper cover 1. The spring 10 keeps the disc of the upper grinding disc 2 under a downward force. The magnitude of the force is determined by the elastic force of the spring 10. In actual use, the solid waste is located below the upper grinding disc 2. When the solid waste is too hard, in order to protect the device, when the force on the lower end face of the upper grinding disc 2 exceeds the elastic force of the spring 10, the upper grinding disc 2 will move upward to allow the solid waste to pass through, thereby avoiding damage to the device.
[0022] The upper end of the inner wall of the outer shell 3 is provided with a limiting platform 31. The upper grinding disc 2 is installed above the limiting platform 31. The limiting platform 31 is used to control the height of the upper grinding disc 2 so that the lower end face of the upper grinding disc 2 and the upper end face of the lower grinding disc 4 maintain a certain gap, preventing the lower end face of the upper grinding disc 2 from directly contacting the upper end face of the lower grinding disc 4 and causing damage. An upper sealing ring 22 is provided on the disc side wall at the lower end of the upper grinding disc 2. The function of the upper sealing ring 22 is to prevent dust from overflowing from the upper end and polluting the environment.
[0023] The lower grinding disc 4 is a disc, and the lower grinding disc 4 is horizontally set below the upper grinding disc 2; a third grinding layer 41 is provided on the upper surface of the lower grinding disc 4; the side wall of the lower grinding disc 4 is in contact with the inner wall of the outer shell 3; a lower sealing ring 42 is provided on the side wall of the lower grinding disc 4; the function of the lower sealing ring 42 is to prevent dust from overflowing from the upper end and polluting the environment.
[0024] The lower end face of the upper grinding disc 2 forms an angle with the upper end face of the lower grinding disc 4. The point of maximum vertical distance between the upper grinding disc 2 and the lower grinding disc 4 is connected to the feed inlet 7 on the side end face of the outer casing 3, and the point of minimum vertical distance between the upper grinding disc 2 and the lower grinding disc 4 is connected to the discharge outlet 8 on the side end face of the outer casing 3. A first grinding layer 21 is provided on the lower end face of the upper grinding disc 2, and a boss 23 is provided on the lower end face of the upper grinding disc 2. The lower end face of the boss 23 is parallel to the upper end face of the lower grinding disc 4, and a second grinding layer 24 is provided on the lower end face of the boss 23. The function of the boss 23 is to control the entry direction of the solid waste. In actual use, the solid waste enters from the feed inlet 7 and rotates around the lower grinding disc 4. The boss 23 moves toward the discharge port 8. Since the distance between the upper grinding disc 2 and the lower grinding disc 4 is set from large to small, larger solid waste cannot pass through. Under the interaction of the first grinding layer 21 and the third grinding layer 41, the solid waste will be gradually ground down to meet the discharge requirements and finally discharged from the discharge port 8. The first grinding layer 21, the second grinding layer 24 and the third grinding layer 41 are made of diamond abrasive. The grinding layers are used to grind the solid waste into smaller particles. A gate valve A is provided at the discharge port 8 on the side wall of the outer shell 3. The gate valve A is used to control the opening and closing of the discharge port 8. The center of the lower end face of the lower grinding disc 4 is connected to the output shaft of the reduction motor 6. The reduction motor 6 is a low-speed motor.
[0025] The usage process of this utility model is as follows: First, assemble the device and fix it to the workbench through the mounting hole 51; before processing the waste, close the gate valve A at the discharge port 8; start the reduction motor 6, at which time the lower grinding disc 4 rotates, and the waste to be processed is fed in from the feed port 7. At this time, the waste moves towards the discharge port 8 as the lower grinding disc 4 rotates. Since the distance between the upper grinding disc 2 and the lower grinding disc 4 is set from large to small, larger solid waste cannot pass through. Under the interaction of the first grinding layer 21 and the third grinding layer 41, the solid waste... Solid waste is gradually ground down to meet discharge requirements. When the waste is too hard, the resistance to the rotation of the lower grinding disc 4 increases. When the resistance exceeds the elastic force of the spring 10, the upper grinding disc 2 moves upward to allow the solid waste to pass through, thus preventing damage to the device. As the lower grinding disc 4 rotates, the unground waste is processed again until it is completely processed. After the device has been running for a period of time, the waste has been processed. The gate valve A is opened to discharge the waste. Finally, the processed waste is collected together for further processing.
[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
[0027] The parts of this utility model not described in detail are existing technologies.
