Description

A chemical material screening machine for chemical industry

Technical Field

The invention relates to the technical field of material screening, in particular to a chemical material screening machine for chemical industry.

Background Art

Chemical material screening machines are widely used in the preparation of chemical products, such as the preparation of flame retardants (PMPP piperazine pyrophosphate). Since flame retardants need to be added to materials such as PP and PE, in order to ensure uniform distribution and not affect the original mechanical properties of materials such as PE, in addition to controlling the addition formula, the particle size and purity of the product must also be guaranteed. During production, the product is crushed after drying. The original process is to directly enter the finished product silo after crushing, but during production, the crushed material will be partially agglomerated when it is transported to the finished product silo through a pipeline. Although the hardness is not large and it can be crushed by hand, it will affect the use of downstream customers, so it is necessary to screen out the agglomerates; and the particle size span of the material after crushing is large, and the downstream requires products with uniform particle size distribution, so it is necessary to screen out products that are too fine and too coarse to ensure that the prepared products meet production requirements.

A commonly used screening equipment is a rotary vibrating screen, which is driven by a motor to rotate the eccentric block, and cooperates with the screen above to achieve screening operations. The position distribution of the eccentric block affects the movement law of the material on the screen surface during screening. Therefore, in order to screen the material more efficiently, it is necessary to continuously debug the eccentric block so that the rotary vibrating screen can achieve the best effect. However, the eccentric block and the motor are usually fixed by bolts and are arranged in the base of the rotary vibrating screen. When adjusting, it is necessary to first remove the screen above and the screen frame, and then open the base to make adjustments, which is not convenient for users to debug. For this reason, a chemical material screening machine for chemical industry is proposed.

DETAILED DESCRIPTION

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

Embodiment 1, referring to Figures 1 to 5, is the first embodiment of the present invention, which provides a chemical material screening machine for chemical industry, including a supporting mechanism 1, and a vibrating mechanism 2 arranged on the supporting mechanism 1, the vibrating mechanism 2 is provided with a receiving chamber 3, and also includes a sifter 4 arranged in the receiving chamber 3; in this embodiment, the operation of the vibrating mechanism 2 can make the receiving chamber 3 vibrate, the chemical material is placed on the sifter 4, and is screened by vibration, the supporting mechanism 1 is used to place the device, and enables the receiving chamber 3 and the vibrating mechanism 2 to vibrate when the vibrating mechanism 2 is running.

Specifically, the support mechanism 1 includes a support seat 10, and a regulating groove 11 arranged on the surface of the support seat 10, and also includes a vibration seat 12 arranged on the support seat 10. In the present embodiment, the support seat 10 is placed on the ground, and a plurality of regulating grooves 11 are provided, and are evenly spaced and circumferentially distributed on the surface of the support seat 10. The arrangement of the regulating grooves 11 can facilitate the debugging personnel to put their hands into the support seat 10 to debug the vibration mechanism 2. The vibration seat 12 is composed of an elastic member, a positioning block, and a docking plate. The receiving chamber 3 is connected through the vibration seat 12. While the vibration seat 12 provides support for the receiving chamber 3, it can allow the receiving chamber 3 to generate a certain degree of movement, thereby generating vibration, and screening the chemical materials through the sifter 4.

Specifically, the accommodating chamber 3 includes a chassis 30 connected to the vibration seat 12, and a lower frame 31 arranged on the chassis 30, an upper frame 32 is arranged on the lower frame 31, and a dust cover 33 is arranged on the upper frame 32. It should be noted that the sifter 4 includes a supporting screen plate 40 and a screen 41 arranged in the accommodating chamber 3, a movable constraint frame 42 is arranged between the supporting screen plate 40 and the screen 41, and a plurality of movable vibration balls 43 are arranged in the constraint frame 42, wherein the vibration seat 12 and the chassis 30, the lower frame 31 and the upper frame 32, and the upper frame 32 and the dust cover 33 are all connected through a connector 5, and the connector 5 is composed of a connecting frame 50 and a locking device 51. The connecting frame 50 can be tightened by the locking device 51 to complete the docking between the various structures.

When the vibration mechanism 2 is in operation, the vibration causes the holding chamber 3 and the screen 4 to vibrate, and the chemical material enters the holding chamber 3 through the opening above the dust cover 33, and passes through the screen 41 with the vibration. During the vibration process, the vibrating ball 43 will jump between the supporting screen plate 40 and the screen 41, knocking the screen 41, thereby improving the screening efficiency and screening effect of the screen 41.

Preferably, the vibration mechanism 2 includes a screen 41, an eccentric assembly 20 arranged on the driving member 21, and a support frame 22 arranged on the outer wall of the driving member 21; in this embodiment, the driving member 21 is a driving motor, and two eccentric assemblies 20 are provided, and are symmetrically arranged at the upper and lower ends of the driving member 21. The driving member 21 can control the eccentric assembly 20 to rotate, and the rotation of the eccentric assembly 20 can make the support frame 22 vibrate. The support frame 22 is connected to the containing chamber 3, and the vibration of the support frame 22 will drive the containing chamber 3 to vibrate together, and then the chemical material is screened by the sifter 4 inside the containing chamber 3.

The eccentric assembly 20 includes a shaft body 200 arranged on the driving member 21, and a pendulum member 201 rotatably arranged on the shaft body 200. The outer wall of the shaft body 200 is provided with a clamping member 202, and also includes a limiting member 203 arranged outside the shaft body 200; in the present embodiment, the rotating shaft of the driving member 21 is fixedly connected to the end of the shaft body 200, and when the shaft body 200 rotates, it can drive the pendulum member 201 to rotate. When the pendulum member 201 rotates, it deflects due to centrifugal force. During the deflection process, the pendulum member 201 can maintain the clamping connection with the clamping member 202. The limiting member 203 can limit the deflection angle of the pendulum member 201 when it is not rotating, so as to prevent the clamping connection between the pendulum member 201 and the clamping member 202 from being detached.

When in use, the vibration state of the vibration mechanism 2 can be changed by controlling the No. 1 pendulum 201 to be connected to different parts of the clamping part 202. The operator can adjust the eccentric component 20 at the bottom of the driving member 21 through the adjustment groove 11. Since there is a gap between the vibration seat 12 and the support seat 10, the operator can directly reach his hand above the support seat 10 to adjust the eccentric component 20 at the top of the driving member 21.

Specifically, a connecting groove 200a is provided on the outer wall of the shaft body 200, and a blocking plate 200b is provided on the outer wall of the shaft body 200; the clamping member 202 includes a clamping plate 202a provided on the outer wall of the connecting groove 200a, and a long groove 202b provided on the clamping plate 202a. In the present embodiment, a plurality of long grooves 202b are distributed in a circle with equal spacing on the outer wall of the clamping plate 202a. The blocking plate 200b can limit the maximum deflection angle of the No. 1 pendulum component 201, and the long groove 202b is used to clamp with the No. 1 pendulum component 201, thereby limiting the position of the No. 1 pendulum component 201.

Furthermore, the No. 1 pendulum component 201 includes a No. 1 rotating ring 201a rotatably arranged on the outer wall of the shaft body 200, and a No. 1 supporting shaft 201b fixedly arranged on the outer wall of the No. 1 rotating ring 201a, a No. 1 connecting rod 201c rotatably arranged on the No. 1 supporting shaft 201b, and also includes a No. 1 counterweight block 201d fixedly arranged at the end of the No. 1 connecting rod 201c, and a No. 1 insert 201e is arranged at the end of the No. 1 connecting rod 201c. In the present embodiment, the No. 1 supporting shaft 201b is an L-shaped structure.

Among them, a support plate 200c and a limit plate 200d are fixedly provided on the outer wall of the shaft body 200, and a limit strip 200e is fixedly provided on the outer wall of the shaft body 200; the limit member 203 includes a spring 203a sleeved on the outer wall of the shaft body 200, and a push ring 203b provided at the end of the spring 203a, the push ring 203b is slidably connected to the outer wall of the shaft body 200, in this embodiment, four limit strips 200e are provided, and are distributed in a circle with equal intervals on the outer wall of the shaft body 200, the support plate 200c is connected to one end of the spring 203a, the push ring 203b can slide on the outer wall of the shaft body 200, and the movement of the push ring 203b is limited by the limit strip 200e, so that it cannot rotate between the shaft body 200, and the elastic force provided by the spring 203a can make the push ring 203b have a tendency to move close to the limit plate 200d.

Due to the elastic force of the spring 203a, the push ring 203b will approach and fit the limit plate 200d. At this time, the push ring 203b can limit the rotation of the No. 1 connecting rod 201c, so that the No. 1 plug 201e and the long groove 202b remain plugged in and connected. When the driving member 21 drives the shaft 200 to rotate, the No. 1 connecting rod 201c rotates due to the centrifugal force, and the No. 1 plug 201e deflects and enters the long groove 202b. After entering the long groove 202b, the No. 1 plug 201e can maintain a larger resistance area, thereby improving the strength of the structure. The No. 1 counterweight block 201d can rotate, thereby causing the vibration mechanism 2 to vibrate and screen the chemical materials.

When adjusting the position of the No. 1 pendulum member 201 at both ends of the driving member 21, by pressing the push ring 203b, the push ring 203b loses the interference with the No. 1 connecting rod 201c after being pressed, and the No. 1 connecting rod 201c can make the No. 1 plug 201e disengage from the insertion of the long groove 202b through further deflection. At this time, the position of the No. 1 counterweight block 201d can be changed by rotating the No. 1 rotating ring 201a, and then the position of the No. 1 pendulum member 201 at both ends of the driving member 21 can be adjusted. The vibration state of the vibration mechanism 2 can be changed by changing the position of the No. 1 pendulum member 201. After the adjustment is completed, the push ring 203b is reset under the elastic force of the spring 203a.

Embodiment 2, referring to FIG. 1 to FIG. 5 , is the second embodiment of the present invention. Different from the previous embodiment, the clamping member 202 also includes a short slot 202c provided on the clamping plate 202a. In this embodiment, the number of the short slots 202c and the long slots 202b corresponds to each other, and the short slots 202c and the long slots 202b are distributed in an intermittent manner. When in use, when the No. 1 plug 201e and the short slot 202c are controlled to be plugged in, the No. 1 pendulum member 201 can not be deflected during the rotation process. By limiting the distance between the No. 1 counterweight block 201d and the shaft body 200, the vibration state of the vibration mechanism 2 can also be adjusted.

Preferably, the inner wall of the clamping disk 202a is rotatably connected to the inner wall of the connecting groove 200a; the clamping disk 202a is evenly provided with multiple ones from bottom to top; the limiting member 203 also includes an arc plate 203c fixed on the push ring 203b, and an insertion strip 203d fixed on the inner wall of the arc plate 203c. In this embodiment, all the clamping disks 202a can be rotated, and the arc plate 203c is provided with multiple insertion strips 203d, and the multiple insertion strips 203d can be inserted into the long groove 202b or the short groove 202c.

When in use, the push ring 203b can be pressed to separate the insert 203d and the long slot 202b or the short slot 202c, and the short slot 202c and the long slot 202b can be aligned by controlling the rotation of the clamping plate 202a at different positions. When the No. 1 connecting rod 201c rotates, the No. 1 connecting rod 201c can be blocked by the short slot 202c, thereby limiting the rotation angle of the No. 1 connecting rod 201c, so that the distance between the No. 1 counterweight block 201d and the shaft body 200 is changed, further increasing the adjustment range and facilitating precise control.

The rest of the structure is the same as that of Example 1.

Embodiment 3, referring to Figures 1 to 8, is the third embodiment of the present invention. Different from the previous embodiment, the eccentric assembly 20 also includes a No. 2 pendulum member 204 rotatably arranged on the shaft body 200; the No. 2 pendulum member 204 includes a No. 2 rotating ring 204a rotatably arranged on the outer wall of the shaft body 200, and a No. 2 supporting shaft 204b fixedly arranged on the outer wall of the No. 2 rotating ring 204a, a No. 2 connecting rod 204c is rotatably arranged on the No. 2 supporting shaft 204b, and also includes a No. 2 counterweight block 204d fixedly arranged at the end of the No. 2 connecting rod 204c, and a No. 2 insert 204e is arranged at the end of the No. 2 connecting rod 204c. In this embodiment, the working principle of the No. 2 pendulum member 204 is similar to the working principle of the No. 1 pendulum member 201. Through the joint action of the No. 2 pendulum member 204 and the No. 1 pendulum member 201, the adjustment and distribution of the weight at both ends of the driving member 21 can be further improved, so that the adjustment mode of the vibration state is increased.

Specifically, a pin 201f is fixedly provided on the No. 1 rotating ring 201a; an arc-shaped groove 204f is opened on the No. 2 rotating ring 204a; the outer wall of the pin 201f and the inner wall of the arc-shaped groove 204f are slidably connected. In this embodiment, the connection strength between the No. 1 rotating ring 201a and the No. 2 rotating ring 204a can be improved by the pin 201f and the arc-shaped groove 204f, and the maximum deformation angle of the No. 1 rotating ring 201a and the No. 2 rotating ring 204a can be limited.

Furthermore, the size of the No. 1 counterweight 201d is smaller than that of the No. 2 counterweight 204d; the No. 1 counterweight 201d is provided with an inner sliding surface 201g; the No. 2 counterweight 204d is provided with an outer sliding surface 204g. In this embodiment, the weight of the No. 2 counterweight 204d is greater than that of the No. 1 counterweight 201d, so the No. 2 counterweight 204d can have a larger deflection angle when rotating, that is, the No. 2 counterweight 204d will deflect first before the No. 1 counterweight 201d. Referring to FIG. 7, the inner sliding surface 201g and the outer sliding surface 204g The setting can ensure that when the No. 1 counterweight 201d and the No. 2 counterweight 204d are deflected, only the No. 2 counterweight 204d can be deflected first, and the No. 1 counterweight 201d can be deflected together, and when resetting, only the No. 1 counterweight 201d can be reset first, and the No. 2 counterweight 204d can be reset. Therefore, it can be ensured that when the driving member 21 drives the eccentric assembly 20 to rotate and stop rotating, the position between the No. 1 counterweight 201d and the No. 2 counterweight 204d can remain relatively stable, thereby improving the stability and reliability of the eccentric assembly 20 during operation.

Preferably, the No. 1 counterweight 201d is provided with an upper conical surface 201h and a lower conical surface 201i, and the No. 1 insert piece 201e is provided with an inclined insert surface 201j; in the present embodiment, the arrangement of the No. 1 upper conical surface 201h and the No. 1 lower conical surface 201i facilitates the spring 203a to push the push ring 203b close to the limit plate 200d, and facilitates the push ring 203b to contact the No. 1 connecting rod 201c to limit the position of the No. 1 counterweight 201d, and the arrangement of the No. 1 inclined insert surface 201j facilitates the alignment and insertion of the No. 1 insert piece 201e with the long slot 202b and the short slot 202c.

In the present embodiment, the arrangement of the No. 2 upper conical surface 204h and the No. 2 lower conical surface 204i facilitates the spring 203a to push the push ring 203b close to the limit plate 200d, and facilitates the push ring 203b to contact the No. 2 connecting rod 204c to limit the position of the No. 2 counterweight 204d. The arrangement of the No. 2 inclined insert surface 204j facilitates the alignment and insertion of the No. 2 insert piece 204e with the long slot 202b and the short slot 202c.

The rest of the structure is the same as that of Example 2.

In summary, by controlling the positions of the No. 1 pendulum component 201 and the No. 2 pendulum component 204 at the upper and lower ends of the driving component 21, as well as the angle between the No. 1 pendulum component 201 and the No. 2 pendulum component 204, and the maximum deflection angle of the No. 1 pendulum component 201 and the No. 2 pendulum component 204, the vibration state of the vibration mechanism 2 can be adjusted, thereby changing the vibration state of the chemical material during screening, making it easier to adapt to different chemical materials, thereby improving the efficiency and effect of screening.
