[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0031] Please see Figure 5-6 As shown, this utility model provides a technical solution for an integrated drying and grinding device for leeches: The integrated drying and grinding device for leeches designed in this way mainly consists of two parts: a drying and screening chamber 1 and a grinding and drying chamber 2. The two are connected by a telescopic mechanism. The three hidden slots 10 of the telescopic mechanism are arranged in a circumferential array on the upper surface of the drying and screening chamber 1. An electric push rod 11 is installed in each hidden slot 10. The telescopic end of the electric push rod 11 is fixed to the bottom surface of the grinding and drying chamber 2. A high-temperature resistant sealing ring is installed on the upper surface of the drying and screening chamber 1. Support legs are set at the bottom. A PLC controller is installed on the surface. A feed inlet 5 is set on the top cover 3. When it is not necessary to clean the material on the vibrating screen 92, the drying and screening chamber 1 and the grinding and drying chamber 2 are closed and sealed by the high-temperature resistant sealing ring. Moreover, the electric push rod 11 is retracted into the hidden slot 10.
[0032] like Figure 2 and 3 As shown, both the drying and screening chamber 1 and the grinding and drying chamber 2 have inner chambers 6 on their inner walls. Heating tubes 61 are arranged around the inner chambers 6. The heating tubes 61 can be common heating elements such as resistance heating wires. Temperature sensors are installed in both inner chambers 6, and the detection probes of the temperature sensors extend into the drying and screening chamber 1 and the grinding and drying chamber 2 to detect their internal temperature. With the cooperation of the PLC controller, the heating temperature and time of the heating tubes 61 can be controlled.
[0033] like Figure 3-4As shown, the grinding and drying chamber 2 is internally fixed with an upper grinding disc 7 and a lower grinding disc 71. The upper surface of the upper grinding disc 7 has a conical protrusion in the middle, which is fixed to the inner wall of the grinding and drying chamber 2 by a connecting column and has a gap, so that the powdered material can fall into the lower grinding disc 71 through the gap by centrifugal force during high-speed grinding. The upper surface of the lower grinding disc 71 is concave, and a discharge port 72 is opened in the middle. The drive mechanism 4 is installed on the top cover 3 and includes a motor housing 41, a drive motor, a reducer and a drive shaft 42. The drive shaft 42 extends through the top cover 3 into the interior of the grinding and drying chamber 2. The output end of the drive motor is connected to the drive shaft 42 through the reducer. The drive shaft 42 is connected to the top cover 3 by a bearing to ensure smooth rotation of the drive shaft 42.
[0034] like Figure 3 and 4 As shown, the grinding roller assembly includes a lower grinding roller 46 and an upper grinding roller 45. The lower grinding roller 46 is connected to the bottom end of the drive shaft 42, located on the upper surface of the lower grinding disk 71, and has a gap with the surface of the lower grinding disk 71. Its lower shape is adapted to the inner shape of the lower grinding disk 71. The upper grinding roller 45 is mounted on the surface of the drive shaft 42 through a fixed seat 43 and a support rod 44, located on the upper surface of the upper grinding disk 7 and has a gap with it. In the grinding roller assembly, the lower grinding roller 46 is fixed to the bottom end of the drive shaft 42, and the upper grinding roller 45 is rotatably connected to the fixed seat 43 through the support rod 44. The fixed seat 43 is fixed to the surface of the drive shaft 42. By rotating the drive shaft 42, the lower grinding roller 46 and the upper grinding roller 45 can be driven to perform grinding operations on the lower grinding disk 71 and the upper grinding disk 7, respectively.
[0035] like Figure 4 As shown, the cleaning mechanism 8 is installed on the fixed base 43 and consists of a support rod 81, a connecting rod 82, a front scraper 83, and a cleaning brush 84. The bottom surface of the front scraper 83 contacts the surface of the upper grinding disc 7, and the bristles on the lower surface of the cleaning brush 84 contact the surface of the upper grinding disc 7. The support rod 81 of the cleaning mechanism 8 is fixed on the fixed base 43, and the lower end of the connecting rod 82 is connected to the front scraper 83 and the cleaning brush 84 respectively through a connecting plate. Moreover, the front scraper 83 and the cleaning brush 84 can be disassembled for easy maintenance. In addition, the top cover 3 can also be opened to facilitate cleaning of the grinding and drying chamber 2.
[0036] like Figure 3 As shown, a receiving hopper 9 is installed inside the drying and screening chamber 1. A detachable vibrating screen 92 is installed inside the receiving hopper 9, and multiple vibrating motors 91 are installed on the outer side. The bottom of the receiving hopper 9 is funnel-shaped, and a discharge port 93 is opened at the bottom. After the leeches are dried and ground, they fall onto the vibrating screen 92 inside the receiving hopper 9. The vibrating screen 92 is used to vibrate and screen the materials, and the materials that meet the particle size requirements fall into the bottom of the receiving hopper 9 through the vibrating screen 92 and are discharged from the discharge port 93.
[0037] The working principle of this utility model is as follows: First, the dried leeches are placed into the grinding and drying chamber 2 through the feed port 5 on the top cover 3. The heating tube 61 and temperature sensor in the grinding and drying chamber 2 and the drying and screening chamber 1 are started to heat up the grinding and drying chamber 2 and the drying and screening chamber 1 to facilitate the initial drying of the leeches. At the same time, the drive motor of the drive mechanism 4 works at low speed, driving the drive shaft 42 to rotate, which in turn drives the upper grinding roller 45 and the lower grinding roller 46 to rotate slowly at low speed. During the drying process, the upper grinding roller 45 rotates on the upper surface of the upper grinding disc 7, and the lower grinding roller 46 rotates on the upper surface of the lower grinding disc 71, which slightly grinds and turns the leeches. On the one hand, it makes the leeches heat more evenly and improves the drying efficiency. On the other hand, it performs low-speed grinding treatment on the leeches.
[0038] Once the leeches are dried to a certain degree, the PLC controller controls the drive motor to work at high speed, driving the upper grinding roller 45 and the lower grinding roller 46 to rotate at high speed, thus fully grinding the dried leeches. The drying process can continue during the grinding process. In addition, during the grinding process, the cleaning mechanism 8 rotates with the rotation of the drive shaft 42. The front scraper 83 and the cleaning brush 84 continuously clean the surface of the upper grinding disc 7, scraping off and sweeping away the material attached to the surface of the upper grinding disc 7 to avoid material residue and ensure the grinding effect and the cleanliness of the equipment.
[0039] Moreover, the conical protrusion design in the middle of the upper surface of the upper grinding disc 7 can guide the material to spread in all directions, making it easier for the upper grinding roller 45 to grind. The concave design of the upper surface of the lower grinding disc 71 is adapted to the lower shape of the lower grinding roller 46, which can make the material better gather and grind during the grinding process. The ground material falls into the receiving hopper 9 in the drying and screening chamber 1 through the discharge port 72 in the middle of the lower grinding disc 71.
[0040] After the material falls into the receiving hopper 9, the vibrating motor 91 is started. The vibrating motor 91 drives the vibrating screen 92 to vibrate and screen the ground material. The material that meets the particle size requirements falls into the bottom of the receiving hopper 9 through the vibrating screen 92 and is discharged from the discharge port 93. The material that does not meet the particle size requirements remains on the vibrating screen 92 and can be manually removed and added to the grinding and drying chamber 2 for further grinding. Moreover, the ground leech powder that falls on the vibrating screen 92 can continue to be dried using the temperature in the drying and screening chamber 1 during the vibrating screen, further improving the drying efficiency of the leech.
[0041] The entire processing is controlled by a PLC controller on the surface of the drying and screening chamber 1. Parameters such as heating temperature, drying time, grinding speed, and vibration frequency of the vibrating screen can be set to achieve automated operation and improve the stability and reliability of the processing.
[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
