Description

Technical Field

[0001] This utility model belongs to the field of waste pill technology in pill production, and particularly relates to a waste pill recycling device for pill production. Background Technology

[0002] Pills, such as those used in traditional Chinese medicine, are spherical preparations of traditional Chinese medicine. Due to their convenience of administration, pills are widely used in traditional Chinese medicine preparations.

[0003] In the pill production process, the pills first need to be rolled into shape using a pill-rolling equipment. After being formed, the pills need to be sieved through a rotary screen. The rotary screen removes unqualified pills by tumbling through the screen. Unqualified pills are mainly defective products such as irregular shapes or damaged pills. Qualified pills are retained in the sieve body of the rotary screen.

[0004] Substandard pills need to be recycled. However, since the pills have not been dried after being rolled into pellets, they are highly sticky. When they are directly crushed and recycled using a pulverizer, a large number of pills stick together to form lumps and easily adhere to the blades of the pulverizer.

[0005] Therefore, in existing technologies, the waste pellets after pelletizing often need to be dried in drying equipment, such as an oven, to dry the pellets before they are crushed. However, the drawback of this method is that a large number of recycled waste pellets need to be placed on drying racks and pushed into the oven, which is often used to dry normally produced pellets in the workshop, thus occupying normal production equipment.

[0006] Secondly, after drying, the pellets and drying rack need to cool down before the operator pushes the drying rack out of the oven and adds the pellets on the rack into the pulverizer. This method requires a certain amount of time for cooling, which makes it difficult to quickly recycle and process the waste pellets. Furthermore, the high-speed production line often generates a continuous stream of waste pellets. Therefore, the continuously generated waste pellets need to be quickly recycled and processed, and the recycled materials should be reused as raw materials in the production equipment to avoid the accumulation of recycled materials.

[0007] Therefore, it is crucial to improve the efficiency of waste pellet recycling by using a quick-drying, quick-baking, and rapid-entry crushing process after drying, and immediately feeding the crushed recycled material into the pellet processing equipment for mixing. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide a device for recycling waste pellets from pellet production.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A waste pellet recycling device for pellet production includes a wet pellet drying mechanism, wherein the wet pellet drying mechanism includes a drying hopper installed at the feed inlet of a crusher, and a mesh frame assembly is assembled and connected inside the drying hopper;

[0011] The space frame assembly includes a hingedly mounted downward-folding space structure and a matching upward-folding space structure; wet shot is located between the downward-folding space structure and the upward-folding space structure;

[0012] It also includes a hot air mechanism for pumping hot air into the drying hopper, with the air outlet of the hot air mechanism located between the lower and upper screen structures.

[0013] Preferably, the drying hopper includes a rectangular cylindrical hopper section and a conical hopper section at the bottom of the integrally formed rectangular cylindrical hopper section;

[0014] The discharge end of the conical hopper is fixedly installed at the feed inlet of the crusher;

[0015] The downward flipping net structure and the upward flipping net structure are hinged and installed inside the rectangular cylindrical bucket.

[0016] Preferably, the downward-folding mesh structure includes a hinged downward-folding mesh frame, and a metal mesh is fixedly connected inside the downward-folding mesh frame;

[0017] The bottom two sides of the flip-down mesh frame are respectively hinged with lower electric push rods that push the flip-down mesh frame to flip.

[0018] The lower electric push rod is hinged and installed on the side wall of the rectangular cylindrical bucket.

[0019] Preferably, the upward-turning mesh structure includes an upward-turning mesh frame that is hinged and installed, and a metal mesh is fixedly connected inside the upward-turning mesh frame;

[0020] The top two sides of the flip-up net frame are respectively hinged with upper electric push rods that push the flip-up net frame to flip.

[0021] The upper electric push rod is hinged to a support column, which is fixedly installed on the top of the drying hopper.

[0022] Preferably, the hot air mechanism includes a hot air blower, and the outlet end of the hot air blower is connected to a hot air exhaust spring tube;

[0023] The exhaust air spring tube is connected and installed on the rectangular cylindrical bucket.

[0024] Preferably, an air inlet is provided on the side wall of the rectangular cylindrical hopper, and a flange is fixedly installed at the air outlet end of the heat exhaust spring tube, and the flange is fastened to the air inlet by bolts.

[0025] Preferably, a dust extraction structure is installed above the drying hopper.

[0026] Preferably, the exhaust dust removal structure includes an exhaust hood, the bottom of which is fixedly installed on the top of the supporting column;

[0027] The exhaust hood is connected to a spring-loaded air duct at its outlet, and the spring-loaded air duct is connected to an external exhaust pipe.

[0029] Preferably, a feeding operation hole is provided on the side wall of the extended air duct.

[0030] This utility model has the following beneficial effects:

[0031] 1. The hopper can dry waste pellets (wet pellets), allowing them to be quickly dried and then directly fed into the crusher's chamber for further crushing. Simultaneously, the waste pellets are added back into the drying hopper for further drying. This ensures continuous waste pellet processing and rapid crushing. This method significantly shortens the waste pellet processing cycle, allowing waste pellets from production to be quickly reused as raw materials in the pellet production batching equipment, avoiding the accumulation of large amounts of recycled material.

[0032] 2. During the operation, when the waste shot is fed, the upper electric push rod flips the upper flipping screen frame-metal baffle to a horizontal position, thereby forming a cage structure with the upper flipping screen frame-metal baffle and the lower flipping screen frame-metal baffle, and the wet shot is placed in the cage structure.

[0033] At this time, the upward-turning mesh frame and metal baffle are used to prevent the upward hot air flow from blowing the dried pellets out of the drying hopper during the hot air drying process. As the drying degree of the waste pellets increases, the weight of the waste pellets decreases, especially the broken pellets.

[0034] 3. The drying process is achieved through a structure consisting of a downward-folding mesh frame, a metal baffle, and a lower electric push rod, allowing for rapid unloading and immediate crushing. Attached Figure Description

[0046] Example 1

[0047] like Figure 1-6 As shown, a waste pellet recycling device for pellet production includes a wet pellet drying mechanism, which includes a drying hopper 2 installed at the feed inlet of a crusher. Specifically, existing crushers all have a feeding hopper installed at the feed inlet, and the material is fed from the hopper and crushed during the crushing process.

[0048] However, the hoppers on existing crushers are incapable of drying materials. Therefore, this invention improves the structure of the hopper on existing crushers, enabling the hopper to dry waste pellets (wet pellets). After rapid drying, the pellets are directly fed from the hopper into the crusher's chamber for further crushing. Simultaneously, the waste pellets are then added back to the drying hopper 2 for further drying. This achieves uninterrupted processing of waste pellets.

[0049] Specifically, the drying hopper 2 is equipped with a mesh frame assembly 4; the mesh frame assembly 4 includes a hinged downward mesh structure and a matching upward mesh structure; the wet pellets are located between the downward mesh structure and the upward mesh structure.

[0050] During operation, waste pellets are fed directly from the drying hopper 2. The waste pellets are supported on the top-turning mesh structure. At this time, the top-turning mesh structure is flipped to a horizontal closed state, so that the waste pellets are placed in the drying chamber formed between the top-turning mesh structure, the top-turning mesh structure and the side wall of the drying hopper 2.

[0051] Specifically, the drying hopper 2 includes a rectangular cylindrical hopper section and a conical hopper section at the bottom of the integrally formed rectangular cylindrical hopper section; the discharge end 21 of the conical hopper section is fixedly installed at the feed inlet of the crusher (the installation method is the conventional installation method of crusher hopper disclosed in the prior art, specifically, a flange ring is welded on the discharge end 21 of the conical hopper section, and the flange ring is fastened to the feed inlet of the crushing equipment by bolts).

[0052] The aforementioned downward-turning mesh structure and upward-turning mesh structure are hinged and installed inside the rectangular cylindrical bucket.

[0053] Specifically, the flip-down mesh structure includes a flip-down mesh frame 42 that is hinged (the hinge method is: pins are fixedly connected to the two side walls at the rear end of the flip-down mesh frame 42, and the pins are hinged to the rectangular cylindrical hopper). While ensuring that the flip-down mesh frame 42 can flip normally, a sufficiently small gap is maintained between the flip-down mesh frame 42 and the inner side wall of the drying hopper 2 (to prevent the pellets from leaking down from the gap).

[0054] At the same time, a metal mesh 43 (made of stainless steel and capable of bearing 20-30 kg of material) is fixedly connected.

[0055] Under normal circumstances, the downward tilting screen frame 42 is in a horizontal position, and the waste pellets are loaded on the downward tilting screen frame 42. After drying is completed, the downward tilting screen frame 42 flips down and pours the dried waste pellets through the conical part of the drying hopper 2 into the crushing equipment.

[0056] The net frame 42 then flips down and returns to a horizontal position.

[0057] Specifically, the bottom front end of the bottom of the flip-down net frame 42 is hinged to two sides, and the lower electric push rods 421 are hinged to the side wall of the rectangular cylindrical bucket.

[0058] The hinge method is as follows: the pushing end of the lower electric push rod 421 is fixedly installed with a hinge sleeve, and the bottom sides of the lower flip-up mesh frame 42 are fixedly installed with hinge brackets, and the hinge brackets are fixedly installed with fixed pins that are hinged to the hinge sleeve.

[0059] Meanwhile, the bottom of the lower electric push rod 421 is fixed with an upper hinge tongue, which is fixedly mounted on the side wall of the rectangular cylindrical bucket by a pin.

[0060] After drying is complete, pour the material out in the manner described above, and then flip it to a horizontal position. At this time, the upward flipping screen structure opens (flips upward) to pour the waste pellets into the drying hopper 2, and then the upward flipping screen structure flips to a horizontal position.

[0061] Specifically, the principle and structure of the flip-up net structure are the same as those of the downward flip-up net structure. The above-mentioned upward flip-up net structure includes an upward flip-up net frame 41 that is hinged and installed. A metal baffle 43 is fixedly connected inside the upward flip-up net frame 41 (the metal baffle 43 at this position is mainly used to block dust, so the mesh design is smaller).

[0062] The top two sides of the top of the flip-up mesh frame 41 are respectively hinged to an upper electric push rod 411 (the hinge method is the same as that of the upper electric push rod 411); the upper electric push rod 411 is hinged to a support column 412 (the hinge method is the same as that of the upper electric push rod 411), and the support column 412 is fixedly installed on the top of the drying hopper 2.

[0063] During operation, when the waste shot is fed, the upper electric push rod 411 flips the upper flipping mesh frame 41-metal baffle 43 to a horizontal position, thereby forming a mesh cage structure with the upper flipping mesh frame 41-metal baffle 43 and the lower flipping mesh frame 42-metal baffle 43, and the wet shot is placed in the mesh cage structure.

[0064] At this time, the upward-turning mesh frame 41 and the metal baffle 43 are used to prevent the upward-facing hot airflow from blowing the dried fragments out of the drying hopper 2 during the hot air drying process. As the degree of drying of the waste pellets increases, the weight of the waste pellets decreases, especially the broken pellets.

[0065] Specifically, in order to achieve rapid drying, hot air with a high flow rate is often used in actual work to dry the waste pellets into a state that can be fully pulverized in a short time (the material should not stick together during the pulverization process).

[0066] The aforementioned electric push rods are all conventional electric telescopic rods disclosed in the prior art. The upper and lower flip-up net frames are made of aluminum alloy, thus they can be easily pushed by the electric telescopic rods. Furthermore, the lower electric push rod pulls the flip-up net frame downwards, making it even easier to pull it down.

[0067] Example 2

[0068] like Figure 1-6 As shown, this embodiment, based on the structure of embodiment 1, further includes a hot air mechanism for pumping hot air into the drying hopper 2 in order to achieve hot air drying. The air outlet of the hot air mechanism is located between the lower flip-up mesh structure and the upper flip-up mesh structure.

[0069] Specifically, the hot air mechanism includes a hot air blower 1 (the hot air blower 1 is a conventional hot air blower 1 used in conventional industrial production processes disclosed in the prior art, which can pump out a hot air stream of a certain flow rate and a certain temperature for drying materials, etc.), and the air outlet end of the hot air blower 1 is connected to a hot air exhaust spring tube 11; the hot air exhaust spring tube 11 is connected and installed on the rectangular cylindrical bucket.

[0070] Specifically, an air inlet is provided on the side wall of the rectangular cylindrical bucket, and a flange is fixedly installed at the air outlet end of the exhaust air spring tube 11. The flange is fastened to the air inlet by bolts.

[0071] In the above manner, the hot air blower 1 pumps hot air into the drying hopper 2, which then enters a cage structure formed by the upper flip-up mesh frame 41-metal baffle 43 and the lower flip-up mesh frame 42-metal baffle 43. The wet pellets are placed in the cage structure and are quickly dried and dehumidified by the pumped hot air.

[0072] During this process, the hot airflow for drying moves downwards and upwards, thereby achieving rapid drying of the pellets.

[0073] Example 3

[0074] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 2, in order to reduce the amount of dust generated during the drying process, an exhaust dust removal structure is installed above the drying hopper 2.

[0075] The dust extraction structure includes a dust extraction hood 3, the bottom of which is fixedly installed on the top of a support column 412 (specifically, a pad is fixedly installed on the top of the support column 412, and the dust extraction hood 3 is fixedly installed by fastening bolts on the pad).

[0076] Similar to the existing exhaust hood 3, the exhaust hood 3 has a spring duct 32 connected to its outlet end. The spring duct 32 is connected to an external exhaust pipe (similar to the existing method, the external exhaust pipe is connected to the exhaust system in the workshop to exhaust dust through the exhaust system).

[0077] In actual operation, in order to reduce dust emission, a rectangular flange base is fixedly connected to the bottom of the above-mentioned exhaust hood 3. An extended air duct (specifically by bolts) is detachably installed on the bottom of the rectangular flange base to cover the position above the drying hopper 2.

[0078] By extending the air duct 31 (the transverse cross-section of the extended air duct 31 is rectangular), the distance between it and the drying hopper 2 is reduced during operation, thereby reducing the dispersion of dust.

[0079] Meanwhile, a feeding operation hole A is provided on the front side wall of the extended air duct 31 (the feeding operation hole A increases the feeding space, making it convenient for operators to insert auxiliary tools such as sieves into the drying hopper 2 during the process of feeding waste pellets).

[0080] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
