Description

Technical Field

[0001] The invention relates to the field of stirring equipment, in particular to a batching device for chemical drug production. Background Art

[0002] Chemical drugs are the active ingredients extracted from natural minerals, animals and plants, as well as drugs made through chemical synthesis or biosynthesis, collectively referred to as chemical drugs. In the process of drug synthesis, the dosing equipment required is widely used.

[0003] When the traditional batching device is cleaned after use, water is usually added directly into the batching device, and then the water is stirred inside the batching device by the stirring blade to achieve the cleaning effect. The cleaning efficiency is relatively low. For this reason, there is a foam plastic stirring device with patent number CN214238961U, which uses a scraper in contact with the side wall of the barrel to scrape off impurities on the inner wall of the barrel to solve the above problem. However, the device has the following defects when in use. When the stirring paddle rotates, it will drive the scraper to rotate together, resulting in contact and friction with the inner wall of the barrel when there is no need to clean the inner wall of the barrel. Then, the scraper that is in contact with the inner wall of the barrel for a long time is not only easy to cause wear to the side wall of the barrel and affect its service life, but also the long-term friction between the two affects the stirring of the material in the barrel by the stirring paddle. Summary of the invention

[0004] The purpose of the present invention is to provide a batching device for chemical production.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

[0006] A batching device for chemical production includes a barrel, wherein a stirring mechanism is arranged on the top of the barrel, and the stirring mechanism includes a motor, a rotating shaft driven by the motor, and a stirring paddle arranged on the rotating shaft:

[0007] A mounting block connected to the motor output shaft is provided at the top of the rotating shaft, wherein a through hole is horizontally provided on the mounting block, and a screw tube is provided in the through hole, and the screw tubes on both sides of the mounting block are jacketed with limit tubes, wherein both ends of the screw tube are screwed with screws, and the end of the screw is connected to a scraper, and the scraper is arranged in the barrel outside the stirring paddle, wherein a cross bar corresponding to the stirring paddle is provided on one side of the scraper, and a fixed channel for accommodating the cross bar is provided at the end of the stirring paddle, wherein N-pole magnetic blocks are provided in the fixed channel and at the end of the cross bar.

[0008] Preferably, an observation window and a manhole are provided on the top cover plate of the barrel body just above the spiral tube.

[0009] Preferably, bristles are provided on the outer side wall of the scraper, wherein the distance between the bristles and the corresponding inner wall of the barrel body is smaller than the length of the cross bar in the fixed channel.

[0010] Preferably, the diameter of the limiting tube is larger than the inner diameter of the through hole, and the size of the spiral tube is adapted to the size of the through hole.

[0011] Preferably, the limiting tube is provided with a gear ring on the outer sleeve, wherein a gear meshing with the gear ring is provided in the barrel body, and a round rod extending to the outside of the barrel body is provided at one end of the gear, and a plurality of groups of protrusions corresponding to the round rods are provided at the top of the barrel body, wherein the protrusions are provided with round holes for the round rods to pass through, the round rod is located above the scraper, and a magnetic block is provided on the round rod between the protrusion and the inner wall of the barrel body.

[0012] The beneficial effects of the present invention are as follows: the present invention fixes two sets of screws through the screw tube, and the screw rods fix two sets of scrapers, thereby making the scrapers away from the inner wall of the barrel body. Therefore, when the stirring mechanism drives the scrapers to rotate, the scrapers will not contact the inner wall of the barrel body to generate friction, thereby reducing the resistance to the operation of the stirring mechanism and also improving the service life of the inner wall of the barrel body; when it is necessary to scrape and clean the inner wall of the barrel body, the gear is meshed with the gear ring, then the round rod and the gear can be rotated, and then the gear ring can be used to drive the limit tube to drive the screw tube to rotate in the through hole and on the screw rod. When the screw tube rotates, the distance between the two sets of screw rods inside it will be enlarged, and the outward-moving screw drives the scraper to move outward and resist against the inner wall of the barrel body. At this time, the outward-moving scraper drives the cross bar to slide outward in the fixed channel while being affected by the same Under the influence of the two sets of N-pole magnetic blocks, the cross bar will slide quickly from the fixed channel to the outside, so that the lower half of the scraper is close to the inner wall of the barrel body, so that when the stirring mechanism drives the screw and other components to drive the scraper to rotate, the scraper can better scrape off the impurities on the inner wall of the barrel body, and cooperate with the cleaning liquid to clean it.

DETAILED DESCRIPTION

[0015] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0016] A batching device for chemical production includes a barrel 1, wherein a stirring mechanism 2 is arranged on the top of the barrel 1, and the stirring mechanism 2 includes a motor 21, a rotating shaft 22 driven by the motor 21, and a stirring paddle 23 arranged on the rotating shaft 22:

[0017] A mounting block 3 connected to the output shaft of the motor 21 is provided at the top of the rotating shaft 22, wherein a through hole is horizontally provided on the mounting block 3, and a screw tube 4 is provided in the through hole, and the screw tubes 4 on both sides of the mounting block 3 are jacketed with limit tubes 5, wherein both ends of the screw tube 4 are screwed with screws 6, and the end of the screw 6 is connected to a scraper 7, and the scraper 7 is arranged in the barrel body 1 outside the stirring paddle 23, wherein a cross bar 8 corresponding to the stirring paddle 23 is provided on one side of the scraper 7, and a fixed channel 9 for accommodating the cross bar 8 is provided at the end of the stirring paddle 23, wherein N-pole magnetic blocks 10 are provided in the fixed channel 9 and at the end of the cross bar 8.

[0018] In this embodiment, an observation window and a manhole are arranged on the top cover plate of the barrel body 1 just above the spiral tube 4.

[0019] like Figure 1 As shown, bristles are arranged on the outer wall of the scraper 7 , wherein the distance between the bristles and the corresponding inner wall of the barrel body 1 is smaller than the length of the cross bar 8 in the fixed channel 9 .

[0020] In this embodiment, the diameter of the limiting tube 5 is larger than the inner diameter of the through hole, and the size of the spiral tube 4 is adapted to the size of the through hole.

[0021] like Figure 1 As shown, a gear ring 11 is provided on the outer sleeve of the limiting tube 5, wherein a gear 12 meshing with the gear ring 11 is provided in the barrel body 1, and a round rod 13 extending to the outside of the barrel body 1 is provided at one end of the gear 12, and a plurality of groups of protrusions 14 corresponding to the round rod 13 are provided on the top of the barrel body 1, wherein the protrusions 14 are provided with round holes for the round rod 13 to pass through, and the round rod 13 is located above the scraper 7, and a magnetic block 15 is provided on the round rod 13 between the protrusion 14 and the inner wall of the barrel body 1.

[0022] The method of use of the present invention: Figure 1 As shown, two groups of screws 6 are fixed by the screw tube 4, and the screws 6 fix two groups of scrapers 7, so that the scrapers 7 are kept away from the inner wall of the barrel body 1. When the stirring mechanism 2 drives the scrapers 7 to rotate, the scrapers 7 will not contact with the inner wall of the barrel body 1 to generate friction, thereby reducing the resistance to the operation of the stirring mechanism 2 and also improving the service life of the inner wall of the barrel body 1. At this time, the round rod 13 drives the magnetic block 15 to be magnetically connected with the inner wall of the barrel body 1, thereby driving the gear 12 to move outward and separate from the gear ring 11, so that the gear 12 and the round rod 13 will not affect the rotation of the stirring mechanism 2 and the scrapers 7;

Then, the round rod 13 and the gear 12 can be rotated, and then the limit tube 5 can be driven through the gear ring 11 to drive the screw tube 4 to rotate in the through hole and on the screw 6. When the screw tube 4 rotates, the distance between the two sets of screws 6 inside it will be enlarged, and the outward-moving screw 6 drives the scraper 7 to move outward and abut against the inner wall of the barrel body 1. At this time, the outward-moving scraper 7 drives the cross bar 8 to slide outward in the fixed channel 9, while being affected by the same Under the influence of the two groups of N-pole magnetic blocks 10, the cross bar 8 will quickly slide outward from the fixed channel 9, so that the lower half of the scraper 7 is tightly attached to the inner wall of the barrel body 1, so that when the stirring mechanism 2 drives the screw 6 and other components to drive the scraper 7 to rotate, the scraper 7 can better scrape off the impurities on the inner wall of the barrel body 1 and cooperate with the cleaning liquid to clean it.
