Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicinal material drying, and in particular to energy-saving heat-insulating drying equipment for wolfberry processing. Background Art

[0002] Traditional Chinese medicine is mainly composed of plant medicine, animal medicine and mineral medicine. Because plant medicine accounts for the majority of traditional Chinese medicine, it is also called Chinese herbal medicine. There are about 5,000 kinds of traditional Chinese medicine used in various parts of China, and the prescriptions formed by combining various medicinal materials are countless. In the production process of traditional Chinese medicine, drying is a very important process.

[0003] At present, the commonly used drying equipment for Chinese medicinal materials mainly adopts a static drying method, that is, the Chinese medicinal materials are spread flat on the placement rack. This method can achieve good drying effects when the Chinese medicinal materials are only spread in a single layer and no accumulation occurs. However, when processing medicinal materials such as wolfberries, it is usually necessary to spread the wolfberries to a certain thickness for drying, which inevitably leads to accumulation between the wolfberry particles, resulting in uneven heating and affecting the drying efficiency. In addition, after drying, the wolfberries need to be manually collected layer by layer, which is not only cumbersome but also inefficient. Summary of the invention

When the air guide cover rotates along with the central axis, the wind blown by the fan blades is sent into the upper and lower spaces in the cabinet, and is dispersed by the spiral stirring plates so that the input wind can evenly wrap the medicinal materials.

[0006] As a further description of the above technical solution: The laying frame comprises a surrounding frame, and two semicircular shelves are rotatably connected to the bottom of the inner wall of the surrounding frame. The semicircular shelves are provided with a plurality of elliptical holes that are adapted to the sizes of the fully dried wolfberries.

[0007] As a further description of the above technical solution: One side of the two surrounding frames is equipped with a swing unit; The swing unit includes an arc guide seat, one side of the arc guide seat is slidably connected to an arc slider in an arc slide groove, one side of the arc slider is rotatably connected to an arc telescopic rod through a connecting column, and one end of the central axis that penetrates into the heat preservation and drying cabinet is connected to the arc telescopic rod.

[0008] As a further description of the above technical solution: The inner top wall of the heat preservation and drying cabinet is rotatably connected with a vertical shaft, a positioning plate is fixed to the bottom end of the vertical shaft, a mounting plate is detachably fixed to the lower surface of the positioning plate, and the top end of the vertical rod is detachably fixed to the lower surface of the mounting plate.

[0009] As a further description of the above technical solution: A discharging unit is provided on the lower surface of the semicircular shelf; The discharging unit includes a material receiving barrel mounted on a vertical rod, a material discharge trough is provided in the middle of the inner bottom wall of the material receiving barrel, a frustum is clamped in the material discharge trough, a connecting frame is fixed on the frustum through a support, a supporting frame is provided on the lower surface of the semicircular shelf, a connecting rod is fixed on the outer walls of a plurality of the supporting frames, and the connecting frame is detachably fixed to the lower surface of the lowest supporting frame.

[0010] As a further description of the above technical solution: A material guide table is arranged below the heat preservation drying cabinet, an electric push rod is fixed to the lower surface of the material guide table, and one end of the electric push rod that penetrates into the heat preservation drying cabinet is connected to the cone through a bearing.

[0011] As a further description of the above technical solution: The air guide cover is detachably fixed on the central axis, and one end of the air guide cover is rotatably connected to the inner wall of the heat preservation and drying cabinet.

[0012] As a further description of the above technical solution: The air supply unit also includes an air inlet frame fixed on the outer wall of the heat preservation and drying cabinet, a motor is installed in the middle of the outer wall of the air inlet frame, the output end of the motor is spline-connected to one end of the central axis, and the top and bottom of the outer wall of the air inlet frame are clamped with filters by opening air inlet grooves.

[0013] As a further description of the above technical solution: A mounting frame is detachably fixed on the inner wall of the air inlet frame, and a plurality of heating wires are arranged on the mounting frame.

[0014] As a further description of the above technical solution: The spiral stirring plate is provided with a variable diameter air outlet channel connected with the air supply pipe, and an air deflector plate is fixed on one side of the lower surface of the mounting plate and one side of the material receiving barrel.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. Through the set medicinal material laying unit, swing unit and air supply unit, after the wolfberries of the same specifications are placed in the laying frame, the central axis drives the fan blades to send the air heated by the electric heating wire into the heat preservation drying cabinet to dry the wolfberries. During the process, the central axis drives the arc telescopic rod to rotate, and then drives the arc guide seat to rotate the laying frame periodically left and right through the arc slider, so that the wolfberries can remain active during the drying period, avoid being piled up for a long time, and ensure that the wolfberries can be heated evenly; At the same time, when supplying air, the air supply pipe can supply air to the upper and lower spaces in the cabinet at intervals during the rotation process to ensure the uniform temperature in the cabinet. During the rotation process, the spiral stirring plate continuously stirs the hot air in the cabinet to make the hot air distribution more even, avoiding the situation where the temperature of the cabinet space far from the air outlet is lower than that of the space near the air outlet, further ensuring that the wolfberry is heated evenly. 2. Through the semicircular shelf and the discharging unit, during the drying process of wolfberries, the dried wolfberries gradually fall down layer by layer through the elliptical holes on the surface of the semicircular shelf as the laying frame swings, and the staff does not need to pour out the wolfberries layer by layer after opening the cabinet door. It is only necessary to place the collection frame for receiving the dried wolfberries in front of the material guide table, and then drive the cone table downward by the electric push rod to open the discharge chute, so that the wolfberries collected in the material receiving barrel can fall into the collection frame as a whole. At the same time, after the cone table moves down, the support frame also moves down. In this state, the semicircular shelf tilts downward under the action of its own gravity. At this time, the wolfberries left on its surface will also slide downward due to the tilting force, thereby ensuring that the wolfberries can be completely collected.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1 - Fig.11 As shown, the present invention provides: An energy-saving heat preservation and drying device for processing wolfberry, comprising a heat preservation and drying cabinet 10, wherein a medicinal material laying unit 20 is installed in the heat preservation and drying cabinet 10, wherein the medicinal material laying unit 20 comprises a round table 21 which is assembled and rotatably connected to the inner bottom wall of the heat preservation and drying cabinet 10, wherein a plurality of laying frames 23 are fixed on the round table 21 through a vertical rod 22, wherein specifically, a slot matching the vertical rod 22 is provided on the surface of the round table 21, wherein the bottom end of the vertical rod 22 is inserted into the slot, and a hexagonal bolt is threadedly connected on the outer wall of the round table 21, wherein after the vertical rod 22 is inserted into the slot, the vertical rod 22 can be fixed in the slot by tightening the bolt, and the subsequent disassembly is convenient; like Figure 2 , Figure 3 and Figure 8 As shown, the laying frame 23 includes a surrounding frame 231, and two semicircular shelves 232 are rotatably connected to the bottom of the inner wall of the surrounding frame 231. The semicircular shelves 232 are provided with a plurality of elliptical holes 233 that are adapted to the size of the fully dried wolfberries. In particular, when the wolfberries are fully dried, they can fall downward through the elliptical holes 233. Specifically, a first sliding frame that is adapted to the vertical rod 22 is fixed on the outer wall of the surrounding frame 231, and a first bolt is threadedly connected to the outer wall of the first sliding frame. The vertical rod 22 is provided with a plurality of threaded holes that are adapted to the first bolt, so that the surrounding frame 231 can be fixed to the vertical rod 22 through the first bolt on the first sliding frame; like Figure 2 , Figure 3 , Figure 4 and Fig. 9 As shown, one side of the two surrounding frames 231 is jointly equipped with a swing unit 30; The swing unit 30 includes an arc guide seat 31, one side of the arc guide seat 31 is slidably connected to an arc slider 33 in an arc slot 32, one side of the arc slider 33 is rotatably connected to an arc telescopic rod 34 through a connecting column, and one end of the central axis 41 that penetrates into the heat preservation and drying cabinet 10 is connected to the arc telescopic rod 34; The inner top wall of the heat-insulating drying cabinet 10 is rotatably connected to a vertical axis, a positioning plate is fixed to the bottom end of the vertical axis, a mounting plate 24 is detachably fixed to the lower surface of the positioning plate, and the top of the vertical rod 22 is detachably fixed to the lower surface of the mounting plate 24. Specifically, during the rotation of the central axis 41, the arc telescopic rod 34 will be driven to rotate together, thereby driving the arc guide seat 31 through the arc slider 33 to drive the laying frame 23 to perform periodic reciprocating rotation left and right around the vertical axis. At the same time, by adjusting the length of the arc telescopic rod 34, the amplitude of the left and right rotation of the laying frame 23 can be changed. The left and right rotation of the laying frame 23 can make the wolfberries placed in the laying frame 23 shake periodically to avoid accumulation, so that the wolfberries can fully contact with the hot air during the drying period, thereby accelerating the drying process.

[0020] like Figure 4 and Fig. 9 As shown, an air supply unit 40 is mounted on the outer wall of the heat preservation drying cabinet 10. Preferably, a discharge hole is opened on one side of the inner wall of the heat preservation drying cabinet 10, and a solenoid valve is provided in the discharge hole, which can remotely control the opening and closing of the discharge hole and the flow rate; The air supply unit 40 includes a central axis 41 rotatably connected to the heat preservation drying cabinet 10, a fan blade 42 is mounted on the central axis 41, and an air outlet member 43 connected to the central axis 41 is mounted on the inner wall of the heat preservation drying cabinet 10; The air supply unit 40 also includes an air inlet frame 44 fixed on the outer wall of the heat preservation drying cabinet 10, a motor 45 is installed in the middle of the outer wall of the air inlet frame 44, the output end of the motor 45 is spline-connected to one end of the central axis 41, the top and bottom of the outer wall of the air inlet frame 44 are clamped with filters by opening air inlet slots, and a mounting frame is detachably fixed on the inner wall of the air inlet frame 44, and a plurality of electric heating wires 46 are arranged on the mounting frame; Specifically, when the starter motor 45 controls the central axis 41 to drive the fan blades 42 to rotate, the power of the heating wire 46 is turned on, so that the wind blown out through the fan blades 42 is heated by the heating wire 46 and enters the heat preservation and drying cabinet 10 to dry the wolfberries.

[0021] like Figure 4 , Figure 7 , Fig. 9 and Fig.10 As shown, the air outlet member 43 includes an air guide cover 431 and an air supply pipe 432 mounted on the air guide cover 431. The air guide cover 431 is detachably fixed to the central axis 41, and one end of the air guide cover 431 is rotatably connected to the inner wall of the heat preservation and drying cabinet 10. A plurality of air supply holes 433 are provided on the air supply pipe 432. A plurality of spiral stirring plates 434 are mounted at the bottom of the outer wall of the air supply pipe 432. The air guide cover 431 rotates along with the central axis 41 to deliver the air blown by the fan blades 42 into the upper and lower spaces in the cabinet, and is dispersed by the spiral stirring plates 434 so that the delivered air can evenly wrap the medicinal materials. A variable diameter air outlet channel 435 connected to the air supply pipe 432 is provided in the spiral stirring plate 434. Preferably, the inner diameter of the variable diameter air outlet channel 435 decreases from the air inlet to the air outlet, so that the air entering the variable diameter air outlet channel 435 can be accelerated and then sent out. A deflector plate 436 is fixed to one side of the lower surface of the mounting plate 24 and one side of the receiving barrel 51. Specifically, during the left and right periodic rotation of the laying frame 23, the mounting plate 24 and the material receiving barrel 51 will be driven to move together, so that the air deflector plate 436 can swing left and right. During the process, the wind blown out from the air supply hole 433 can be shifted to both sides, thereby improving the fluidity of the hot air and making the hot air distribution more even. At the same time, during the rotation of the air supply pipe 432, when the air supply hole 433 rotates to the bottom to supply air to the lower space, the spiral stirring plate 434 is at the top, and the wind accelerated by the variable diameter air outlet channel 435 will impact the hot air in the upper space. Similarly, during the rotation process, the wind delivered by the variable diameter air outlet channel 435 will continuously impact the hot air at different positions, thereby improving the fluidity of the hot air.

[0022] like Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the lower surface of the semicircular shelf 232 is provided with a discharging unit 50; The discharging unit 50 includes a receiving barrel 51 assembled on the vertical rod 22. Preferably, a plurality of through holes are provided on the inner bottom wall of the receiving barrel 51. A material discharge trough is provided in the middle of the inner bottom wall of the receiving barrel 51. A cone 52 is clamped in the material discharge trough. A connecting frame is fixed on the cone 52 through a support column 53. A supporting frame 54 is provided on the lower surface of the semicircular shelf 232. A connecting rod 55 is fixed on the outer walls of the plurality of supporting frames 54. The connecting frame is detachably fixed to the lower surface of the lowest supporting frame 54. In particular, a plurality of holes larger than the elliptical hole 233 are provided on the surface of the supporting frame 54 to prevent the wolfberries in the middle from getting stuck on the holes on the surface of the supporting frame 54 when falling. Specifically, a second sliding frame adapted to the vertical rod 22 is fixed on the outer wall of the receiving barrel 51, and a second bolt is threadedly connected on the outer wall of the second sliding frame. Through the second bolt, the position of the receiving barrel 51 can be fixed after being sleeved on the surface of the vertical rod 22; A material guide table 57 is installed below the heat preservation drying cabinet 10. An electric push rod 56 is fixed to the lower surface of the material guide table 57. One end of the electric push rod 56 that penetrates into the heat preservation drying cabinet 10 is connected to the cone 52 through a bearing. Specifically, after drying is completed, the collection frame for receiving the dried wolfberries is placed in front of the material guide platform 57, and then the electric push rod 56 is started to drive the cone 52 to move downward, so that the material discharge chute is gradually opened, so that the wolfberries collected in the receiving barrel 51 can fall down through the material discharge chute to the surface of the material guide platform 57 and then slide into the collection frame for collection. After the cone 52 moves downward, the support 53 will also drive the support frame 54 to move downward, so that the semicircular shelf 232 tilts downward, and the wolfberries remaining on the surface of the semicircular shelf 232 will slide downward. When there are wolfberries remaining in the elliptical hole 233 on the surface of the semicircular shelf 232, the cone 52 is controlled by the electric push rod 56 to move back and forth up and down, so that the semicircular shelf 232 shakes, so that the wolfberries in the hole can also be cleaned out, and no subsequent secondary cleaning is required.

[0023] Specifically, when the energy-saving heat preservation drying equipment for wolfberry processing is working / in use: 1. Laying out medicinal materials: Spread a certain amount of wolfberries on each layer of the semicircular shelf 232; 2. Start the device: The motor 45 is started to rotate the central axis 41, driving the fan blades 42 and the air outlet 43 to rotate, and at the same time, the electric heating wire 46 is powered on to start heating and air supply. The rotation of the central axis 41 also drives the arc guide seat 31 through the arc telescopic rod 34 to drive the laying frame 23 to perform periodic reciprocating rotation left and right, so that the medicinal materials remain in an active state; 3. Drying process monitoring: Observe the temperature and humidity changes in the heat preservation drying cabinet 10 to ensure that the drying process proceeds smoothly, and adjust the power and air supply of the heating wire 46 as needed to control the drying speed and effect; 4. Discharging after drying: Turn off the power of the motor 45 and the heating wire 46, wait for the equipment to cool down, and then place the collection frame for receiving the dried wolfberries in front of the material guide table 57, then start the electric push rod 56 to drive the cone 52 to move downward, so that the discharge chute gradually opens, and the wolfberries fall into the collection frame from the receiving barrel 51. If there are still residual wolfberries on the surface of the semicircular shelf 232 or in the elliptical hole 233, the electric push rod 56 can be used to control the cone 52 to move back and forth up and down, so that the semicircular shelf 232 will shake, and the residual wolfberries can be cleaned up.

[0024] 5. Equipment cleaning and maintenance: Clean the residual medicinal materials and dust inside the heat preservation drying cabinet 10 and on the laying frame 23 and other components, and check whether the various components of the equipment are intact. If there is any damage or wear, replace or repair it in time.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
