Description

Technical Field

[0001] The utility model relates to the technical field of polyacrylamide grinding, in particular to a polyacrylamide vibration screening and grinding device. Background Art

[0002] Polyacrylamide is a linear organic macromolecular polymer and also a macromolecular water treatment flocculant product, which can specifically adsorb suspended particles in water and act as a bridge between particles. During processing, a grinder is usually used to grind polyacrylamide to make powder particles.

[0003] When the existing polyacrylamide vibration screening and grinding device is used, the polyacrylamide raw materials are first screened by a vibrating screen plate and then ground. When a large amount of material is fed at one time, it is difficult to complete rapid screening by relying on vibration alone, and the raw materials are easily accumulated on the surface of the screen plate, resulting in reduced screening efficiency.

[0004] Therefore, in order to address the problem that raw materials are easily accumulated on the surface of the screen when the above-mentioned existing polyacrylamide vibration screening and grinding device is in use, thereby reducing the screening efficiency, a material shifting structure can be designed that can continuously shift the raw materials on the surface of the screen during operation to avoid raw material accumulation and reduce screening efficiency. Utility Model Content

[0005] In order to overcome the problem that when a large amount of material is fed at one time in the existing polyacrylamide vibration screening and grinding device is in use, it is difficult to complete rapid screening by relying on a single vibration of the screen plate, and the raw materials are easily accumulated on the surface of the screen plate, resulting in reduced screening efficiency.

[0006] The technical scheme of the utility model is: a polyacrylamide vibration screening and grinding device, comprising an equipment shell; also comprising a screw, a movable seat, a connecting rod and a material shifting rod, bases are installed at the corners of the bottom surface of the equipment shell, a top cover is arranged on the top surface of the equipment shell, material guide plates are installed on the left and right sides of the upper position of the inner surface of the equipment shell, the ends of the two material guide plates are connected with electromagnetic valves, the upper surface of the electromagnetic valve is provided with a grinding roller, a protective cover is installed on the front side surface of the equipment shell, screws are rotatably connected to the upper ends of the left and right sides of the inner surface of the equipment shell, the outer surface of the screw is threadedly connected to the movable seat, a connecting rod is installed on the bottom surface of the movable seat, an array-distributed material shifting rod is installed on the bottom surface of the connecting rod, and a material discharge port is arranged on the bottom surface of the equipment shell.

[0007] Preferably, by setting a screw rod, when the screw rod rotates, the moving seat threadedly connected to its surface will move left and right, thereby driving the connecting rod to move left and right, so that the material pushing rod at the bottom of the connecting rod can push the polyacrylamide material, improving the screening efficiency, and thus solving the problem that in the existing polyacrylamide grinding device during use, no pushing structure is provided on the surface of the sieve plate, and the material is likely to accumulate on the surface of the sieve plate, resulting in a reduction in screening efficiency.

[0008] As a preference, at the upper end of the left surface of the equipment housing, a first mounting plate is provided, and on the upper surface of the first mounting plate, a driving motor is provided. The output end of the driving motor is connected to the left end surface of the screw rod. By setting the driving motor, during operation, it will drive the screw rod to rotate, thereby realizing the automated operation of the material pushing process.

[0009] As a preference, at the upper front side of the inner surface of the equipment housing, a positioning groove is opened. On the front end surface of the connecting rod, a positioning block is installed, and the positioning block is slidably connected to the positioning groove. By opening the positioning groove, when the connecting rod moves, the positioning block will slide inside the positioning groove, and the positioning groove can limit the sliding direction of the positioning block, improving the smoothness of the device operation.

[0010] As a preference, at the upper part inside the equipment housing and below the connecting rod, a first sieve plate is provided. On the front and rear side surfaces of the first sieve plate, sliding blocks are installed, and the first sieve plate is slidably connected to the inner surface of the equipment housing through the sliding blocks. By setting the sliding blocks, the first sieve plate can be easily disassembled and assembled by means of sliding insertion, so as to facilitate the replacement of the first sieve plate with different pore diameters to adapt to the screening requirements.

[0011] As a preference, a recovery channel is installed on the left surface of the equipment housing. At both the front and rear ends of the top surface of the recovery channel, air extraction pumps are installed. At a lower position inside the equipment housing, a second sieve plate is provided. By setting the second sieve plate, the ground polyacrylamide material will fall onto the surface of the second sieve plate for screening. The qualified powder will fall downward to the discharge port, and the powder with larger particle size will remain on the surface of the second sieve plate. At this time, when the air extraction pumps are started, the powder with larger particle size will be transported again to the grinding operation end through the recovery channel under the action of suction for secondary grinding, so as to improve the finished product quality.

[0012] As a preference, on the left surface of the second sieve plate, a hinge rod is installed. On the right side of the bottom surface of the second sieve plate, symmetrically arranged hinge seats are installed. The output end of an electric push rod is connected to the bottom surface of the hinge seat, and the bottom surface of the electric push rod is connected to the inner bottom surface of the equipment housing. By the telescoping of the electric push rod, the right end of the second sieve plate will be tilted upward, and the left end will rotate around the hinge rod, so as to pour the material on the surface of the second sieve plate towards the suction inlet of the recovery channel, facilitating the suction of the material.

[0013] Preferably, a second mounting plate is installed at the upper position of the front surface of the equipment shell, and a vibration motor is installed on the upper surface of the second mounting plate. By setting the vibration motor, vibration will be generated during operation, thereby improving the screening efficiency of the first sieve plate and the second sieve plate.

[0014] Advantages of the present utility model:

[0015] 1. By setting the screw rod, when the screw rod rotates, the moving seat threadedly connected to its surface will move left and right, thereby driving the connecting rod to move left and right, so that the feeding rod at the bottom of the connecting rod can stir the polyacrylamide material, improving the screening efficiency, thus solving the problem that in the existing polyacrylamide grinding device during use, no stirring structure is provided on the surface of the sieve plate, and the material is likely to accumulate on the surface of the sieve plate, resulting in a reduction in screening efficiency;

[0016] 2. By setting the driving motor, it will drive the screw rod to rotate during operation, thereby realizing the automated operation of the feeding process. And by opening the positioning groove, when the connecting rod moves, the positioning block will slide inside the positioning groove, and the positioning groove can limit the sliding direction of the positioning block, improving the smoothness of the device operation;

[0017] 3. By setting the second sieve plate, the ground polyacrylamide material will fall on the surface of the second sieve plate for screening. The qualified powder will fall downward to the discharge port, and the powder with larger particle size will remain on the surface of the second sieve plate. At this time, start the air extraction pump, and the powder with larger particle size will be conveyed again to the grinding operation end through the recovery channel for secondary grinding under the action of suction, thereby improving the product quality.
