Description

Technical Field

[0001] This application belongs to the field of feed technology, and specifically relates to an improved structure for feed of p-chlorophenylglycine. Background Technology

[0002] Chlorophenylglycine (chemical formula: C8H8CLNO2), also known as DL-chlorophenylglycine, has a melting point of 220-230℃ and is a toxic substance. It should never be ingested and is irritating to the eyes, respiratory system, and skin. Appropriate protective clothing must be worn when handling chlorophenylglycine. Industrially, it is mainly used for pharmaceutical synthesis. The preparation of chlorophenylglycine requires materials such as ammonia, sodium cyanide, chlorobenzaldehyde, and ammonium bicarbonate. Ammonium bicarbonate needs to be fed into the reactor through a feeding hopper. However, during storage and transportation, ammonium bicarbonate can absorb moisture and clump, affecting the accuracy of the feeding process. Sometimes, the metered powder cannot all enter the reactor, affecting the precise material ratio and consequently the quality of the final product, even causing product spoilage. In existing equipment, ammonium bicarbonate often adheres to the walls of the feeding hopper, hindering accurate feeding.

[0003] Our company's existing patent, application number 201920612184.5, entitled "A Quantitative Feeding Device for the Production of p-chlorophenylglycine," discloses a device comprising a body and a fixing mechanism. The outer wall of the end of the body has a feeding port, a hopper is fixedly connected to the top of the body, and a discharge port is opened at the bottom of the body. A top cover is provided at the top of the hopper, and a handle is fixedly connected to the top of the top cover. The fixing mechanism includes a small steel ball, and a square groove is opened on the lower surface of the top cover. The small steel ball is installed inside the square groove. A slot is opened on the outer wall of the hopper, and a strong magnet is fixedly connected inside the slot. However, during use, it was found that the ammonium bicarbonate in the raw material tends to clump and adhere to the side wall of the hopper, affecting the accuracy of feeding, thus requiring improvement. Utility Model Content

[0004] The purpose of this invention is to provide an improved structure for feeding p-chlorophenylglycine, and to prevent the raw materials (such as ammonium bicarbonate) used to prepare p-chlorophenylglycine from adhering to the inner wall, thus affecting the accuracy of feeding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An improved feeding structure for p-chlorophenylglycine includes a batching silo for feeding various raw materials required for the preparation of p-chlorophenylglycine; it also includes a crushing device disposed within the batching silo, a cleaning device for cleaning adhering substances on the inner wall of the batching silo, and a screw conveyor disposed below the batching silo, wherein the cleaning device is mounted on the crushing device; the screw conveyor is in sealed communication with the batching silo.

[0007] Furthermore, the batching hopper is equipped with a cover; the crushing device includes a crushing shaft rotatably connected to the cover, a reduction motor for driving the crushing shaft to rotate, and a crushing rod fixedly installed on the crushing shaft.

[0008] Furthermore, the crushing rods are arranged in at least three layers from top to bottom along the stirring shaft, with each layer having four crushing rods, and the four crushing rods are evenly distributed along the outer circle of the stirring shaft.

[0009] Furthermore, reinforcing ribs are provided between adjacent breaking rods within each layer.

[0010] Furthermore, the cleaning device includes a support plate fixedly connected to one end of the crushing rod away from the stirring shaft, a silicone plate fixedly connected to the support plate, and a pressure plate fixedly connected to the silicone plate; the pressure plate presses the silicone plate onto the support plate by bolts and nuts; the silicone plate is used to clean the adhesive on the inner wall of the mixing hopper.

[0011] Furthermore, the hatch cover is detachably connected to the ingredient hopper.

[0012] Furthermore, the hatch cover is equipped with a feeding port.

[0013] Compared with the prior art, the significant beneficial effects achieved by this utility model are as follows:

[0014] With the addition of crushing and cleaning devices, when materials such as ammonium bicarbonate are added to the batching hopper, the rotating stirring shaft and crushing rod can break up the lumps of material. At the same time, the silicone plate of the cleaning device scrapes against the inner wall of the batching hopper to prevent it from sticking to the inner wall and affecting the accuracy of feeding.

[0015] By adding reinforcing ribs, the problem of a relatively long crushing rod being fixed to the stirring shaft at only one end, resulting in a weak connection and easy breakage over time, can be avoided. Attached Figure Description

[0024] Example 1

[0025] like Figure 1-4 As shown,

[0026] An improved feeding structure for p-chlorophenylglycine includes a batching silo 1 for feeding various raw materials required for the preparation of p-chlorophenylglycine; it also includes a crushing device 4 disposed within the batching silo 1, a cleaning device for cleaning adhering substances on the inner wall of the batching silo 1, and a screw conveyor 5 disposed below the batching silo 1, wherein the cleaning device is installed on the crushing device 4; the screw conveyor 5 is in a closed connection with the batching silo 1. The screw conveyor 5 is an externally purchased device and belongs to mature existing technology.

[0027] The detailed structure is as follows: the batching bin 1 is equipped with a cover 2; the crushing device 4 includes a stirring shaft 41 rotatably connected to the cover 2, a reduction motor 3 for driving the stirring shaft 41 to rotate, and a crushing rod 44 fixedly installed on the stirring shaft 41.

[0028] The housing of the geared motor 3 is fixed to the cover 2 by bolts, and the output end of the geared motor 3 is fixed to one end of the stirring shaft 41 by a coupling (not shown in the figure, but common knowledge).

[0029] like Figure 2 As shown, the crushing rod 44 is arranged in at least three layers from top to bottom along the stirring shaft 41. One layer is arranged at the bottom of the stirring shaft 41, one layer is arranged near the cover 2, and one layer is arranged on the stirring shaft 41 between these two layers. In this way, the material in the batching bin 1 can be fully crushed.

[0030] like Figure 4 As shown, each layer of the crushing rod 44 is provided with four crushing rods 44, which are evenly distributed along the outer circle of the stirring shaft 41.

[0031] like Figure 3 As shown, the cleaning device includes a support plate 42 fixedly connected to the end of the crushing rod 44 away from the stirring shaft 41, a silicone plate 43 fixedly connected to the support plate 42, and a pressure plate 45 fixedly connected to the silicone plate 43. The pressure plate 45 presses the silicone plate 43 onto the support plate 42 using bolts and nuts. The silicone plate 43 is used to clean the adhesive residue on the inner wall of the mixing hopper 1. The length of the silicone plate 43 is arranged along the length of the inner wall of the mixing hopper 1. Utilizing the elasticity and toughness of the silicone plate, it can adhere tightly to the inner wall of the mixing hopper 1, avoiding scratches to the inner wall caused by inelastic and non-tough plates.

[0032] Work process,

[0033] When a certain amount of various raw materials (methanol, ammonia, sodium cyanide, chlorobenzaldehyde, and ammonium bicarbonate) are added to the mixing silo 1 as needed, the geared motor 3 is started, which drives the stirring shaft 41 to rotate. The stirring shaft 41 drives the crushing rod 44 to rotate, which can crush the lumpy raw materials. When the crushing rod 44 rotates, it drives the silicone plate 43 to scrape along the inner wall of the mixing silo 1, scraping off the ammonium bicarbonate adhering to the silo wall, so as to avoid the adhering material affecting the accuracy of feeding.

[0034] Example 2

[0035] The structure of this embodiment is largely the same as that of Embodiment 1.

[0036] The difference is that,

[0037] like Figure 4 As shown, reinforcing ribs 46 are provided between adjacent crushing rods 44 in each layer. Since only one end of the crushing rod 44 is fixed to the stirring shaft 41, the connection strength of the crushing rod 44 is relatively low, and it is easy to break during use. After setting the reinforcing ribs 46, the overall connection strength can be increased and the service life can be extended.

[0038] Example 3

[0039] The structure of this embodiment is largely the same as that of embodiment 2.

[0040] The difference is that,

[0041] like Figure 1 As shown, the hatch cover 2 is detachably connected to the batching hopper 1. A flange is provided on the top of the batching hopper 1, and a sealing gasket is provided between the hatch cover 2 and the flange. The hatch cover 2 and the flange are fixed together by bolts and nuts.

[0042] The hatch cover 2 is provided with a feeding port 21 and a sealing cover. The port is opened when feeding and closed when not feeding to prevent debris from falling into the mixing chamber 1.
