Description

Technical Field

[0001] The utility model belongs to the technical field of cyclone mills and relates to a full-automatic hammer-type cyclone mill. Background Art

[0002] The hammer cyclone mill is a device used to crush materials and is widely used in the chemical, pharmaceutical, and food industries. Its main working principle is to use high-speed rotating hammers to impact and crush the materials, and then separate the crushed materials from the air flow through a cyclone separator.

[0003] Existing hammer cyclone mills, for example, a hammer cyclone mill disclosed in Chinese patent literature [patent number: 202322013046.4; application publication number: CN220496494U], includes a casing and a feed hopper, a feeding mechanism, a grinding mechanism, a heat dissipation mechanism and a collection mechanism located in the casing. The feed hopper, the feeding mechanism, the grinding mechanism and the collection mechanism are connected by pipes. The heat dissipation mechanism includes a cooling fan and a water cooling plate. The cooling fan is installed in the casing and opposite to the grinding mechanism. The water cooling plate is installed in the grinding mechanism.

[0004] This type of hammer cyclone mill structure enables the use of a hammer cyclone mill to grind a large amount of powder at one time. However, the hammer cyclone mill structure includes a collecting mechanism and a locking mechanism. The collecting mechanism includes an upper collecting mechanism and a lower collecting mechanism. The upper and lower collecting mechanisms are locked by a locking mechanism. The locking mechanism includes a movable part, a locking member, and a fixed member. When connecting, the operator needs to lift the lower collecting mechanism, align the movable part with the fixed member, and then lock it with the locking member, which makes the connection complicated. When disassembling, the operator needs to hold the lower collecting mechanism and then remove the locking members one by one to disconnect the movable part and the fixed member, separating the upper and lower collecting mechanisms so that the sample powder in the lower collecting mechanism can be removed. However, since the collected sample powder in the lower collecting mechanism has a certain weight, it is inconvenient for the operator to hold it and remove the locking member, which makes it difficult to remove the sample powder and clean the collecting mechanism. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems existing in the prior art and to propose a fully automatic hammer cyclone mill, which solves the technical problem of how to make it convenient to take out the sample powder.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a fully automatic hammer cyclone mill, comprising a chassis, a feeding structure, an abrasive structure, a suction tube and a receiving cup arranged in the chassis, the feeding structure being connected to the suction tube through the abrasive structure, and characterized in that a lifting structure is provided in the chassis, the receiving cup is placed on the lifting structure, the bottom of the suction tube has an annular sealing groove, and after the lifting structure drives the receiving cup to move upward, the cup mouth of the receiving cup can be embedded in the sealing groove, so that the receiving cup and the suction tube are sealed and connected.

[0007] During processing, the lifting structure works, and the lifting structure drives the receiving cup to move upward so that the receiving cup and the suction tube are sealed and connected, and the sample is poured into the feeding structure. The feeding structure transports the sample to the abrasive structure, and the abrasive structure grinds the sample into powder. The suction tube is connected to a vacuum system, which generates a vacuum to absorb the powder into the suction tube and drop it into the receiving cup, automatically completing the powder processing. After the processing is completed, the lifting structure drives the receiving cup to move downward so that the receiving cup is separated from the suction tube, and the operator can move the receiving cup down. The receiving cup is easy to take and put, making it easy to take out the sample powder and also easy to clean the receiving cup. The sealing groove is located at the bottom of the suction tube. After the lifting structure drives the receiving cup to move upward, the cup mouth of the receiving cup automatically embeds into the sealing groove. Under the action of the lifting structure, the receiving cup is positioned so that the receiving cup and the suction tube are sealed and connected. After the lifting structure drives the receiving cup to move downward, the cup mouth of the receiving cup automatically leaves the sealing groove. And because the receiving cup is directly placed on the lifting structure, it is easy to remove the receiving cup. The feed structure and the abrasive structure are both existing technologies, and the specific structures are not described in detail.

[0008] In the aforementioned fully automatic hammer cyclone mill, the lifting structure includes a lifting plate with an upwardly bent positioning piece at its peripheral edge. The bottom of the receiving cup can rest against the lifting plate, and the positioning piece can rest against the circumferential outer wall of the bottom of the receiving cup. This structure allows the receiving cup to be placed directly on the lifting plate, and the positioning piece can position the receiving cup, making it easy to place and remove the receiving cup and to remove the sample powder.

[0009] In the above-mentioned fully automatic hammer cyclone mill, the cup opening of the receiving cup has a sealing edge protruding outward along the circumference, and the sealing edge can be embedded in the sealing groove. The provision of the sealing edge increases the contact area, increases the sealing area, and improves the sealing performance.

[0010] In the aforementioned fully automatic hammer cyclone mill, the radial width of the sealing groove of the receiving cup is 1.5-2.5 times the radial width of the sealing baffle. This structure ensures that the mouth of the receiving cup can be inserted into the sealing groove, ensuring a sealed connection between the receiving cup and the suction tube.

[0011] In the above-mentioned fully automatic hammer cyclone mill, a sealing ring is provided in the sealing groove, which improves the sealing performance between the receiving cup and the suction cylinder.

[0012] In the aforementioned fully automatic hammer cyclone mill, the housing includes a recessed space located directly below the suction cylinder. The lifting plate and the receiving cup are both located within the recessed space. The recessed space provides storage space and facilitates the placement and removal of the receiving cylinder, thereby facilitating easy removal of sample powder.

[0013] In the above-mentioned fully automatic hammer cyclone mill, the lifting structure also includes a screw slider assembly and a lifting arm, the inner end of the lifting arm is fixedly connected to the slider of the screw slider assembly, and the outer end extends into the recessed space and is fixedly connected to the lifting plate.

[0014] In the aforementioned fully automatic hammer cyclone mill, the suction cylinder comprises a cylinder body connected to the abrasive structure and a cover body for connecting to a vacuum system. The sealing groove is located at the bottom of the cylinder body. The inner sidewall of the top of the cylinder body has a plurality of spaced L-shaped locking grooves. The outer sidewall of the cover body has a plurality of protruding and spaced locking blocks. The locking blocks fit into the locking grooves and rotate to securely connect the cylinder body and the cover body. This structure facilitates connection and disassembly of the cylinder body and the cover body, and facilitates cleaning of the suction cylinder.

[0015] Compared with the existing technology, the fully automatic hammer cyclone mill provided by the utility model has the following advantages:

[0016] 1. The receiving cup of this hammer cyclone mill is raised and lowered by a lifting structure, so that the receiving cup and the suction tube are sealed by plugging, making it easy to take the receiving cup and place it, thereby making it easy to take out the sample powder and also easy to clean the receiving cup.

[0017] 2. The cylinder body and the cover body of the suction cylinder are fixed by inserting and rotating the locking groove and the locking block. The cylinder body and the cover body are easy to connect and disassemble, making the suction cylinder easy to clean. BRIEF DESCRIPTION OF THE DRAWINGS
