Technical Field
[0001] This utility model relates to the field of screening device technology, specifically a material screening device for chemical product production. Background Technology
[0002] Material screening is a crucial step in chemical production, directly impacting product quality and production efficiency. However, traditional material screening devices for chemical production are often limited to basic screening functions, presenting significant challenges in handling agglomerated materials generated during the screening process. Specifically, chemical materials tend to clump together during screening due to material characteristics, storage conditions, or vibrations during transportation. These agglomerated materials not only affect screening efficiency but can also adversely impact subsequent production processes. Existing screening devices often lack effective methods for handling the filtered-out agglomerated materials.
[0003] Traditional processing methods typically involve collecting the clumps after screening and transferring them to a crushing plant for further crushing before re-screening. This process not only increases the number of steps in the production process and reduces production efficiency, but also increases production costs and the consumption of manpower and resources. Therefore, it is necessary to design a material screening device for chemical product production to solve these problems. Utility Model Content
[0004] The purpose of this invention is to provide a material screening device for chemical product production, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a material screening device for chemical product production, comprising a first support member, a vibrating screen body being slidably connected to the upper end of the first support member, the vibrating screen body being able to reciprocate through a first drive assembly, four sets of shock absorbers being installed at the top of the vibrating screen body, the four sets of shock absorbers being connected to a second support member, the second support member cooperating with a second drive assembly to drive a stirring member to rotate, and the stirring member being universally connected to multiple sets of hammers.
[0006] Preferably, the second drive assembly includes a first motor and a rotating rod. A set of the first motors is mounted on the top of the second support member, and the output end of the first motors is connected to a set of the rotating rods, which are connected to the stirring member.
[0007] Preferably, the stirring component includes a stirring base and stirring rods. The bottom end of the stirring rod is connected to a set of stirring bases.

The bottom end of each set of stirring rods is equidistantly and universally connected to multiple sets of hammers.
[0008] Preferably, two sets of sliding blocks are installed at the bottom of the vibrating screen body, and two sets of sliding rods are installed at the top of the first support member, with the two sets of sliding blocks slidably connected to the two sets of sliding rods respectively.
[0009] Preferably, the first drive assembly includes a third support member, a second motor, a turntable, and a connecting rod. A set of the third support members is installed on one side of the first support member, a set of the second motor is installed on one end of the third support member, the output end of the second motor is connected to a set of the turntable, the turntable is eccentrically hinged to a set of the connecting rods, and the other end of the connecting rods is hinged to one side of the vibrating screen body.
[0010] Preferably, the top plate of the first support member has a set of through holes, and the inner cavity of the first support member can accommodate a set of collection boxes.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. The vibrating screening and hammer crushing processes of this utility model are carried out simultaneously, forming an efficient screening and crushing cycle. The shock absorption components ensure that the two processes are independent and do not interfere with each other, improving the overall work efficiency.

The speed of the first motor and the crushing force of the hammer can be adjusted according to the screening condition and degree of agglomeration of the material to meet different production needs. The hammer's impact on the agglomerated material breaks it down, allowing the crushed material to re-enter the screening process, reducing screening blockage caused by agglomeration. Through continuous and efficient crushing and screening cycles, the overall production efficiency and screening effect are improved. The universal joint design of the hammer and the stirring rod reduces wear and damage caused by material impact and lowers maintenance costs.
[0014] 3. This utility model uses a second motor to drive the turntable to rotate, which in turn drives the connecting rod and the vibrating screen body to reciprocate, thus achieving efficient screening of materials. The reciprocating movement increases the residence time of materials on the screen, improving screening efficiency. The sliding connection design between the slide block and the slide rod ensures that the vibrating screen body remains stable during reciprocating movement and will not deviate from the trajectory due to vibration or external force. This design improves the stability and reliability of the entire screening system. The collection box can be easily placed and removed, facilitating the processing and storage of materials.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1
[0023] Please refer to Figure 1-5 As shown, this utility model provides a material screening device for chemical product production, including a first support member 1. The upper end of the first support member 1 is slidably connected to a vibrating screen body 2. The vibrating screen body 2 can reciprocate through a first drive component. Four sets of shock absorbers 3 are installed at the top of the vibrating screen body 2. The four sets of shock absorbers 3 are connected to a second support member 4. The second support member 4, in conjunction with the second drive component, can drive the agitator to rotate. The agitator is universally connected to multiple sets of hammers 5.
[0024] The vibrating screen body 2 reciprocates through the first drive component. This swaying motion causes the material to be screened on the screen mesh and separated according to particle size. Smaller particles pass through the screen holes more easily due to the combined effects of gravity, vibration, and friction, while larger particles are retained on the screen surface.
[0025] For agglomerated materials, the second drive assembly is activated, driving the agitator to rotate. The agitator is universally connected to multiple sets of hammers 5. As the agitator rotates, the hammers 5 perform circular motion, breaking up the agglomerated materials on the screen. The broken materials then re-enter the screening process, achieving continuous screening and crushing. Four sets of shock absorbers 3 are installed at the top of the vibrating screen body 2. These shock absorbers 3 are connected to the second support member 4. The shock absorbers 3 effectively reduce the impact of the vibration of the vibrating screen body 2 on the circular motion of the hammers 5, ensuring that the hammers 5 can stably perform the crushing operation.
[0026] Vibrating screening and hammer crushing processes are carried out simultaneously, forming an efficient screening and crushing cycle. The shock absorber 3 ensures that the two processes are independent and do not interfere with each other, improving overall work efficiency. There is no need to collect the clumps of material after screening for crushing, saving manpower, material resources and production costs. The efficient screening and crushing cycle reduces equipment downtime and improves equipment utilization and production efficiency.
[0027] Specifically, the second drive assembly includes a first motor 6 and a rotating rod 7. A set of first motors 6 is installed at the top of the second support member 4. The output end of the first motor 6 is connected to a set of rotating rods 7. The rotating rods 7 are connected to the stirring component. The stirring component includes a stirring seat 8 and stirring rods 9. A set of stirring seats 8 is connected to the bottom end of the rotating rods 7. Three sets of stirring rods 9 are installed circumferentially on the outer wall of the stirring seat 8. Multiple sets of hammers 5 are equidistantly connected to the bottom end of each set of stirring rods 9.
[0028] When it is necessary to break up clumps of material, the first motor 6 is started, and the rotating rod 7 rotates accordingly. The bottom end of the rotating rod 7 is connected to the stirring seat 8, which rotates together with the rotating rod 7. Three sets of stirring rods 9 are installed circumferentially on the outer wall of the stirring seat 8. Therefore, when the stirring seat 8 rotates, the stirring rods 9 also make circular motions. Under the action of the universal joint, the hammer 5 can flexibly break up the clumps of material on the screen.
[0029] The universal joint design of the hammer 5 makes the crushing process more flexible and can adapt to agglomerated materials of different shapes and sizes. The speed of the first motor 6 and the crushing force of the hammer 5 can be adjusted according to the screening condition and degree of agglomeration of the material to meet different production needs. The hammer 5 crushes the agglomerated material, allowing the crushed material to re-enter the screening process, reducing screening blockage caused by agglomeration. Through continuous and efficient crushing and screening cycles, the overall production efficiency and screening effect are improved. The universal joint design of the hammer 5 and the stirring rod 9 reduces wear and damage caused by material impact and lowers maintenance costs.
[0030] The vibrating screen body 2 has two sets of sliding blocks 10 installed at its bottom end and two sets of sliding rods 11 installed at its top end. The two sets of sliding blocks 10 are slidably connected to the two sets of sliding rods 11 respectively. The first drive assembly includes a third support 12, a second motor 13, a turntable 14 and a connecting rod 15. A third support 12 is installed on one side of the first support 1. A second motor 13 is installed at one end of the third support 12. The output end of the second motor 13 is connected to a turntable 14. The turntable 14 is eccentrically hinged to a connecting rod 15. The other end of the connecting rod 15 is hinged to one side of the vibrating screen body 2. A set of through holes 16 are opened on the top plate of the first support 1. A set of collection boxes 17 can be placed in the inner cavity of the first support 1.
[0031] When the vibrating screen body 2 needs to reciprocate, the second motor 13 is started, and the turntable 14 rotates accordingly. The turntable 14, as a transmission component, has an eccentric design that is key to achieving the reciprocating movement of the vibrating screen body 2. When the turntable 14 rotates, the connecting rod 15 reciprocates under the action of eccentric force. The other end of the connecting rod 15 is hinged to one side of the vibrating screen body 2. Therefore, the reciprocating movement of the connecting rod 15 will pull the vibrating screen body 2 to reciprocate. The slide block 10 is slidably connected to the slide rod 11, so that the vibrating screen body 2 can remain stable during reciprocating movement and will not deviate from the preset trajectory. The top plate of the first support member 1 has a set of through holes 16, which allow the screened material to fall into the collection box 17 below through the through holes 16. The collection box 17 is placed in the inner cavity of the first support member 1 and is used to collect the screened material.
[0032] The second motor 13 drives the turntable 14 to rotate, which in turn drives the connecting rod 15 and the vibrating screen body 2 to reciprocate, thus achieving efficient screening of materials. The reciprocating movement increases the residence time of materials on the screen and improves screening efficiency. The sliding connection design between the slide block 10 and the slide rod 11 ensures that the vibrating screen body 2 remains stable during reciprocating movement and will not deviate from the trajectory due to vibration or external force. This design improves the stability and reliability of the entire screening system. The collection box 17 can be easily placed and removed, facilitating the processing and storage of materials.
[0033] Working principle: When it is necessary to break up agglomerated materials, the first motor 6 is started, and the rotating rod 7 rotates accordingly. The bottom end of the rotating rod 7 is connected to the stirring seat 8, which rotates together with the rotating rod 7. Three sets of stirring rods 9 are installed circumferentially on the outer wall of the stirring seat 8. Therefore, when the stirring seat 8 rotates, the stirring rods 9 also make circular motion. Under the action of the universal joint, the hammer 5 can flexibly break up the agglomerated materials on the screen. When it is necessary to make the vibrating screen body 2 reciprocate, the second motor 13 is started, and the turntable 14 rotates accordingly. The turntable 14, as a transmission component, has an eccentric design to realize the reciprocating movement of the vibrating screen body 2. The key to the movement is that when the turntable 14 rotates, the connecting rod 15 reciprocates under the action of eccentric force. The other end of the connecting rod 15 is hinged to one side of the vibrating screen body 2. Therefore, the reciprocating movement of the connecting rod 15 will pull the vibrating screen body 2 to move back and forth. The slide block 10 is slidably connected to the slide rod 11, so that the vibrating screen body 2 can remain stable during reciprocating movement and will not deviate from the preset trajectory. The top plate of the first support member 1 has a set of through holes 16, which allow the screened material to fall into the collection box 17 below through the through holes 16. The collection box 17 is placed in the inner cavity of the first support member 1 and is used to collect the screened material.
