Description

Technical Field

[0001] The utility model relates to the technical field of molecular sieve crushing, in particular to a novel molecular sieve crushing device. Background Technique

[0002] Molecular sieve is a kind of synthetic hydrated aluminosilicate (zeolite) or natural zeolite with the function of screening molecules. Molecular sieve has a uniform microporous structure, and the pore diameters of its cavities are uniform. These cavities can adsorb molecules smaller than their diameters into the interior of the cavities, and have a preferential adsorption ability for polar molecules and unsaturated molecules.

[0003] Due to the advantages of high adsorption capacity and strong thermal stability of molecular sieve that other adsorbents do not have, molecular sieve has been widely used. After natural zeolite is collected, it is necessary to dry, purify and separate the zeolite, and crushing is an important part of the process.

[0004] The existing molecular sieve crushing devices usually only have one process of crushing zeolite with a crushing knife, and cannot perform crushing in an autonomous cycle, so the uniformity of zeolite crushing cannot be guaranteed. Moreover, it is necessary to manually screen the incompletely crushed zeolite and then pour it back into the crushing device for secondary crushing, which increases the manual workload and has low crushing efficiency. For this reason, we propose a molecular sieve crushing device. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the background technique, and a novel molecular sieve crushing device is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A novel molecular sieve crushing device includes a fixed seat and a circulating crushing component. A fixed column is fixedly installed on the top of the fixed seat, and a crushing box is fixedly installed on the top of the fixed column. A circulating screening tank is fixedly communicated with the side wall of the crushing box, and a feed hopper is fixedly communicated with the top of the crushing box. A plurality of screening holes are opened at the bottom of the circulating screening tank;

[0008] The circulating crushing component includes a first rotating shaft and a second rotating shaft that respectively pass through the front sides of the crushing box and the circulating screening tank. A reduction motor for driving the second rotating shaft is fixedly installed at the rear side of the circulating screening tank. A plurality of crushing knives are fixedly installed on the surface of a section of the first rotating shaft extending into the crushing box. A plurality of feeding plates are fixedly installed on the surface of a section of the second rotating shaft extending into the circulating screening tank, and the plurality of feeding plates are distributed in a circumferential array. First sprockets and second sprockets are respectively fixedly installed at the end parts of the first rotating shaft and the second rotating shaft, and a transmission chain is jointly sleeved between the first sprocket and the second sprocket.

[0009] Preferably, a collection box is slidably inserted on the side of the fixed seat, and door-shaped handles are fixedly installed on the front and rear side walls of the collection box.

[0010] Preferably, the crushing box is located between the axial horizontal plane and the bottom horizontal plane of the circulating screening tank.

[0011] Preferably, a triangular guide plate is fixedly installed on the inner bottom of the crushing box, and the inclined surface of the triangular guide plate is inclined downward towards the circulating screening tank.

[0012] Preferably, the diameter of the first sprocket is smaller than that of the second sprocket.

[0013] Preferably, a sliding groove for slidably connecting with the collection box is formed on the side of the fixed seat, magnetic blocks are fixedly installed on the opposite sides of the collection box and the fixed column, and the opposite surfaces of the two magnetic blocks attract each other with opposite polarities.

[0014] Compared with the existing technology, the advantages of the novel molecular sieve crushing device of the present invention are as follows:

[0015] By driving the second rotating shaft and the second sprocket to rotate through the reduction motor, under the transmission of the transmission chain, each crushing knife can rotate at a high speed to crush the zeolite. At the same time, each feeding plate can perform a circular motion to re-feed the crushed zeolite particles into the crushing box to contact each crushing knife again, realizing secondary crushing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Referring to Figures 1 - 3 , a new type of molecular sieve crushing device includes a fixed seat 1 and a circulating crushing assembly. A fixed column 2 is fixedly installed on the top of the fixed seat 1, and a crushing box 3 is fixedly installed on the top of the fixed column 2. A circulating screening tank 4 is fixedly communicated with the side wall of the crushing box 3, and a feeding hopper 5 is fixedly communicated with the top of the crushing box 3. The crushing box 3 is located between the axial center horizontal plane and the bottom horizontal plane of the circulating screening tank 4, which is beneficial for the larger zeolite particles in the circulating screening tank 4 to smoothly enter the crushing box 3 for crushing.

[0022] A plurality of screening holes 6 are opened at the bottom of the circulating screening tank 4, and the plurality of screening holes 6 are linearly and arrayedly distributed at the bottom of the circulating screening tank 4. A collection box 15 is slidably inserted into the side of the fixed seat 1. Door-shaped handles are fixedly installed on the front and rear side walls of the collection box 15. A sliding groove 17 connected to the collection box 15 in a sliding manner is opened on the side of the fixed seat 1. The collection box 15 can collect the small-particle zeolites passing through the screening holes 6, and then, by virtue of its sliding connection with the sliding groove 17, it is convenient to remove and install the collection box 15. Magnetic blocks 16 are fixedly installed on the opposite sides of the collection box 15 and the fixed column 2, and the opposite surfaces of the two magnetic blocks 16 attract each other with opposite polarities. After the collection box 15 is installed on the sliding groove 17, the attraction and fitting between the two magnetic blocks 16 can effectively improve the stability of the collection box 15 placed on the device.

[0023] The circulating crushing assembly includes a first rotating shaft 7 and a second rotating shaft 9 that respectively pass through the front sides of the crushing box 3 and the circulating screening tank 4. A reduction motor 11 for driving the second rotating shaft 9 is fixedly installed on the rear side of the circulating screening tank 4. A plurality of crushing knives 8 are fixedly installed on the surface of a section of the first rotating shaft 7 extending into the crushing box 3. A plurality of dialing plates 10 are fixedly installed on the surface of a section of the second rotating shaft 9 extending into the circulating screening tank 4, and the plurality of dialing plates 10 are circumferentially arrayed. First chain wheels 12 and second chain wheels 13 are respectively fixedly installed at the ends of the first rotating shaft 7 and the second rotating shaft 9. A transmission chain 14 is jointly sleeved between the first chain wheel 12 and the second chain wheel 13. The diameter of the first chain wheel 12 is smaller than that of the second chain wheel 13. When the reduction motor 11 controls the second rotating shaft 9 to rotate and the second chain wheel 13 rotates, the first chain wheel 12 can drive the first rotating shaft 7 and each crushing knife 8 to rotate at a high speed under the transmission of the transmission chain 14, so as to improve the crushing effect on the zeolite particles.

[0024] Furthermore, a triangular guide plate 18 is fixedly installed on the inner bottom of the crushing box 3, and the inclined surface of the triangular guide plate 18 is inclined downward toward the circulation screening tank 4, so that the zeolite particles crushed by the crushing knife 8 can slide smoothly along the inclined surface of the triangular guide plate 18 into the circulation screening tank 4 for circulation and screening.

[0025] The working principle of the utility model is:

[0026] When in use, the reduction motor 11 is first started to drive the second rotating shaft 9 and the second sprocket 13 to rotate, and the second rotating shaft 9 drives each material-dispensing plate 10 to move in a circular motion. At the same time, the second sprocket 13, under the drive of the transmission chain 14, can drive the first rotating shaft 7 and each crushing knife 8 to rotate at a high speed through the first sprocket 12, and then the zeolite raw material for preparing the molecular sieve is poured into the feed hopper 5, so that it enters the crushing box 3, and the zeolite can be crushed under the high-speed rotation of the crushing knife 8;

[0027] The crushed zeolite particles can fall into the circulating screening tank 4 under the splash of the triangular guide plate 18 and itself, and can pass through each screening hole 6 under the fluctuation of each material-diverting plate 10. At this time, the smaller zeolite particles will pass through the screening hole 6 and fall into the collecting box 15. On the contrary, the larger zeolite particles will be moved back into the crushing box 3 with the movement of the material-diverting plate 10, and will contact each crushing knife 8 again to achieve secondary crushing. In this way, the automatic circulating crushing effect of the zeolite particles can be achieved, so that there is no need to manually screen the incompletely crushed zeolite and then pour it back into the crushing device for secondary crushing, which reduces the manual workload and also improves the crushing efficiency of the zeolite.

[0028] After the final cycle of crushing is completed, the collecting box 15 is pulled out to pour out the raw materials collected therein.

[0029] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0030] 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. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
