Description
Technical Field
[0001] The utility model relates to the technical field of chemical raw material production equipment, and particularly relates to a chemical material screening device for chemical production. Background Art
[0002] In the process of chemical production, material screening is a key step, which directly affects product quality and production efficiency. In traditional screening devices, during feeding, chemical raw material is directly poured onto the sieve plate of the screening device, or a feeding device is used to feed the sieve plate of the screening device, and the sieve plate is controlled to shake to achieve the screening effect. During the screening process, the amount of material falling on the sieve plate and the feeding speed often affect the screening efficiency of the sieve plate in the screening device. Because when the amount of chemical raw material falling on the sieve plate is greater than the screening rate of the sieve plate, continuous accumulation of chemical raw material on the sieve plate will occur, which will not only affect the screening rate of the sieve plate, but also easily cause blockage of the sieve plate, resulting in frequent shutdowns for cleaning during the production process, increasing production costs and time consumption. If the amount of material falling on the sieve plate is less than the screening rate of the sieve plate, the maximum screening efficiency of the screening device cannot be fully exerted.

[0026] Referring to Figures 1-5 , a chemical material screening device for chemical production, including a support frame 1, a material bucket 2, a discharge hopper 21, a rotating shaft 31, a motor 3, and a sieve plate 202. The material bucket 2 and the discharge hopper 21 are both arranged in the support frame 1, and the discharge hopper 21 is fixedly installed at the bottom of the material bucket 2. Guide rods 22 and two slide rods 23 arranged in parallel are fixedly installed on the inner walls of both sides of the support frame 1. The guide rod 22 and the two slide rods 23 are hermetically slidably connected to the discharge hopper 21 and the material bucket 2 respectively, which can provide stable support for the material bucket 2 and the discharge hopper 21, and at the same time can provide guidance for them when the material bucket 2 and the discharge hopper 21 move reciprocally horizontally. An installation opening is provided at the bottom of the material bucket 2, and the sieve plate 202 is fixedly installed in the installation opening. The top of the material bucket 2 is open and is in hermetically slidable contact with the inner wall of the top side of the support frame 1. A feed pipe 11 communicating with the material bucket 2 is fixedly installed on the support frame 1. The motor 3 is arranged on the top of the support frame 1. The rotating shaft 31 is axially fixedly connected to the output shaft of the motor 3 and extends into the material bucket 2. A support bar 33 is radially fixedly installed on the rotating shaft 31. A first spiral blade 32 and a second spiral blade 34 are respectively fixedly installed on the rotating shaft 31 and the support bar 33, and the spiral directions of the first spiral blade 32 and the second spiral blade 34 are opposite, which can realize the up-and-down turning of chemical raw materials when the rotating shaft 31 rotates;
[0027] Two rotating rods 4 are rotatably mounted on the support bar 33 in the radial direction. At the top ends of the two rotating rods 4, gear discs 42 are fixedly sleeved. On the top inner wall of the support frame 1, a toothed disc 43 is fixedly mounted with the rotating shaft 31 as the center. The two gear discs 42 are both engaged with the toothed disc 43. A plurality of stirring rods 41 are fixedly mounted on each of the two rotating rods 4. When the rotating shaft 31 drives the support bar 33 to move, the rotating rods 4 and the stirring rods 41 can be controlled to stir the chemical raw material in the material barrel 2, so that efficient stirring can be carried out in cooperation with the first spiral blade 32 and the second spiral blade 34. On one inner wall of the support frame 1, a plurality of springs 52 are fixedly mounted. On the side of the plurality of springs 52 away from the inner wall of the support frame 1, they are all fixedly connected to the material barrel 2. On the top inner wall of the support frame 1, a rotating pin 5 is rotatably mounted. At the bottom end of the rotating pin 5, an eccentric wheel 51 that is in movable contact with the outer side of the material barrel 2 is fixedly sleeved. When the rotating pin 5 rotates, the material barrel 2 can be controlled to move to the left through the eccentric wheel 51. At the same time, under the action of the spring 52, the material barrel 2 can be controlled to move to the right as the eccentric wheel 51 rotates, so that the material barrel 2 can move reciprocally left and right. On the rotating shaft 31 and the rotating pin 5, a left pulley 61 and a right pulley 6 are respectively fixedly sleeved. A same belt 62 is drivingly connected between the left pulley 61 and the right pulley 6. When the rotating shaft 31 rotates, the rotating pin 5 can be driven to rotate.
[0028] In this embodiment, in order to enable the rotating rod 4, the stirring rod 41, the first spiral blade 32 and the second spiral blade 34 to better cooperate in the stirring operation and further improve the uniformity of turning and mixing, the rotating rod 4 and the stirring rod 41 are both located between the first spiral blade 32 and the second spiral blade 34. A plurality of dial rods 201 are fixedly mounted on the inner side wall of the material barrel 2.
[0029] In this embodiment, in order to clean the sieve plate 202 while turning and stirring the chemical raw material, so as to avoid the phenomenon of blockage of the sieve plate 202 and at the same time not affect the self-rotation of the rotating rod 4, the bottom ends of the two rotating rods 4 are rotatably mounted with the same scraping bar 35. The scraping bar 35 is in movable contact with the top side of the sieve plate 202, and the scraping bar 35 is fixedly connected to the first spiral blade 32 and the second spiral blade 34.
[0030] In this embodiment, in order to avoid the accumulation of chemical raw materials on the support bar 33, the top side of the support bar 33 is arranged in an arc shape.
[0031] In this embodiment, in order to provide shielding protection for the left pulley 61, the belt 62 and the right pulley 6 and at the same time support the motor 3, a U-shaped plate 12 is fixedly mounted on the top of the support frame 1. The motor 3 is fixedly mounted on the top side of the U-shaped plate 12. The left pulley 61, the belt 62 and the right pulley 6 are all located inside the U-shaped plate 12.
[0032] Working principle: When in use, first turn on the power supply and introduce the chemical raw material to be screened into the material bucket 2 through the feed pipe 11. The motor 3 drives the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 realizes the up-and-down turning of the chemical raw material in the material bucket 2 through the support bar 33, the first spiral blade 32, and the second spiral blade 34, thereby promoting the uniform dispersion of the chemical raw material. At the same time, the rotation of the rotating shaft 31 drives the two rotating rods 4 to rotate through the meshing of the gear 42 and the gear disk 43, and then enables the multiple stirring rods 41 to perform stirring operations in the material bucket 2.
[0033] During the stirring process, the material bucket 2 performs left-right reciprocating motion under the combined action of the spring 52 and the eccentric wheel 51, which helps to further improve the screening efficiency of the sieve plate 202. The rotation of the rotating rod 4 and the stirring rod 41 combined with the reciprocating motion of the material bucket 2 makes the entire stirring process more efficient and uniform, avoiding the situation that the chemical raw material accumulated on the sieve plate 202 affects the normal screening of the sieve plate 202.
[0034] The contact between the scraping bar 35 and the sieve plate 202 can effectively clean the sieve plate 202, prevent blockage, and ensure that the chemical raw material smoothly passes through the sieve plate 202 and enters the discharge hopper 21. In addition, the arc surface design on the top side of the support bar 33 avoids the accumulation of chemical raw materials on the support bar 33, ensuring the smooth operation of the chemical material screening device for chemical production.
[0035] The U-shaped plate 12 not only provides shielding protection for the left pulley 61, the belt 62, and the right pulley 6, but also provides a stable support for the motor 3, ensuring the stability and durability of the entire chemical material screening device for chemical production.
[0036] The above has introduced in detail a chemical material screening device for chemical production provided by the present utility model. Specific embodiments are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
