Description

Technical Field

[0001] The utility model relates to the field of squeezers, in particular to a squeezer for chemical raw materials. Background Art

[0002] Chemical raw material pressing device is a device used to extract chemical raw materials. This device is usually used to squeeze out the active ingredients in plant or animal raw materials for further processing or use. This device can be used to extract a variety of chemical raw materials, such as plant essential oils, animal fats, resins, etc.

[0003] The existing patent number is: CN209666360U, which discloses "A press for processing chemical raw materials". In this patent, the chemical raw materials are added into the filter screen cylinder through the chemical raw material feed pipe, and the bidirectional squeezing drive motor is started. The chemical raw materials are transported to the filter screen cylinder away from one end of the chemical raw material discharge pipe under the rotation of the spiral conveying shaft. The liquid in the chemical raw material is squeezed out through the extrusion between the spiral conveying shaft, the filter screen cylinder and the chemical raw material, and the separated liquid flows into the liquid holding cavity through the filter screen cylinder. At the same time, the separated liquid flows out through the chemical raw material discharge pipe. After the chemical raw material is squeezed, the spiral conveying shaft is rotated in the opposite direction to transport the squeezed chemical raw material to the top of the chemical raw material discharge pipe through the spiral conveying shaft. The squeezed chemical raw material is discharged through the chemical raw material discharge pipe, thereby facilitating the rapid recovery of the chemical raw material. However, in the above patent, a chemical raw material discharge pipe and a chemical raw material liquid discharge pipe are provided to discharge solids and liquids. When there are too many raw materials inside the press box, some unpressed raw materials leak out from the chemical raw material discharge pipe, thereby affecting the normal pressing of all raw materials. At the same time, multiple discharge pipes are provided, and different storage devices need to be placed at different positions, which is extremely inconvenient to operate. Utility Model Content

[0020] When the press is used to squeeze chemical raw materials, the entire press is stably placed by the base frame 1. After the motor 7 is started, the output shaft of the motor 7 rotates with the rotating shaft through the transmission box 8, so that the spiral blade 4 rotates inside the pressing cylinder 2, and the raw materials are added to the pressing cylinder 2 through the feed hopper on the pressing cylinder 2. Under the action of the spiral blade 4, the raw materials move toward the lower hopper 5 and are squeezed, and the liquid in the raw materials is squeezed out and discharged through the lower hopper 5. In this process, the filtering structure 6 plays a filtering role to prevent the solid raw materials from being discharged from the lower hopper 5. When the squeezing work is completed, the filtering structure 6 is started to make way, and the solid raw materials can be discharged from the lower hopper 5.

[0021] According to the above implementation scheme, the filter structure 6 includes a telescopic cylinder 601, a telescopic shaft 603, a filter frame 604, a filter screen 605 and a connecting assembly 606, the telescopic shaft 603 is arranged on the telescopic cylinder 601, the filter screen 605 is installed on the filter frame 604, and the filter frame 604 is connected to the telescopic shaft 603 through the connecting assembly 606, the filter structure 6 also includes a mounting bolt 602, the mounting bolt 602 is arranged on the telescopic cylinder 601, and the telescopic cylinder 601 is fixed to the lower hopper 5 by the mounting bolt 602. The filter screen 605 is fixedly connected to the filter frame 604, and the filter frame 604 passes through the strip hole on the lower hopper 5. The filter frame 604 is provided with a threaded hole 607. The connecting assembly 606 includes a follower rod 6061, a connecting plate 6062, a circular hole 6063 and a connecting bolt 6064. The follower rod 6061 is fixedly connected to the connecting plate 6062, and the follower rod 6061 is connected to the telescopic shaft 603. The circular hole 6063 is provided on the connecting plate 6062, and the connecting plate 6062 is in contact with the filter frame 604. The connecting bolt 6064 passes through the circular hole 6063, and the end of the connecting bolt 6064 is connected to the circular hole 6063. A hopper 5 is provided to cooperate with the filtering structure 6. When the filtering frame 604 is inside the hopper 5, the hopper 5 can only discharge liquid, and the solid is blocked and intercepted by the filtering structure 6. When the filtering frame 604 moves to make way, the hopper 5 can discharge solid. The same hopper 5 can be used to realize batch discharge of solid and liquid, and the use effect is excellent. The upper surface of the filtering frame 604 It is flush with the filter screen 605. During the process of pulling the filter frame 604, the inner wall of the lower hopper 5 can be scraped to prevent solid raw materials from remaining on the filter screen 605. The filter frame 604 is driven by the telescopic cylinder 601, which can not only quickly move the filter frame 604, but also ensure the stability of the filter frame 604 when in use. Through the set connecting component 606, the filter frame 604 and the connecting component 606 are detachably arranged, and can be quickly disassembled and replaced, and can be operated without disassembling the telescopic cylinder 601 and other structures.

[0022] During the squeezing of chemical raw materials, the filter frame 604 with the filter screen 605 is in a closed state, and the filter screen 605 is located inside the lower hopper 5. At this time, when squeezing is performed, the liquid in the raw material passes through the filter screen 605 and is discharged, and the solid remains on the filter screen 605. When the squeezing is completed, the telescopic cylinder 601 fixed by the mounting bolt 602 is started, and the telescopic shaft 603 moves with the filter frame 604 through the connecting component 606, so that the filter frame 604 moves with the filter screen 605 to make way, and the solid raw material can be discharged. The solid can be discharged from the lower hopper 5. After the solid is discharged, the telescopic cylinder 601 is started again, and the telescopic shaft 603 can be reset with the filter frame 604 through the connecting component 606. When necessary, the filter frame 604 can be quickly disassembled for replacement and other operations. When disassembling, the connecting bolts 6064 in the round hole 6063 and the threaded hole 607 are removed, so that the connecting plate 6062 on the follower rod 6061 is no longer fixedly connected to the filter frame 604, and then the filter frame 604 is pulled out to perform related operations. The structure is simple and the operation is convenient and fast.
