Description

Technical Field

[0001] This utility model relates to the field of chemical feeding technology, and in particular to a chemical safety feeding device. Background Technology

[0002] In chemical production processes, it is often necessary to add powdered reactants to reaction vessels. Currently, there are situations where manual feeding of materials is required. However, during material addition, the reaction can sometimes be violent, causing splashing. If the reaction vessel is opened abruptly to add materials, it can pose a safety hazard.

[0003] According to the search, Chinese patent number CN222789172U discloses a chemical safety feeding device. The feeding device includes an operating table and a conveying bin fixedly installed on the operating table, as well as a feed inlet fixedly installed on the top of the conveying bin and a discharge outlet fixedly installed on the bottom of the conveying bin. A drive motor is fixedly installed at one end of the conveying bin on the top of the operating table. An auger that penetrates into the conveying bin is fixedly installed on the output end of the drive motor. A dispersing feeding mechanism is provided at the end of the conveying bin away from the drive motor.

[0004] To avoid the problem of excessively rapid local heating caused by the material being too concentrated in the reaction liquid during feeding, the aforementioned public document adopts a dispersing feeding mechanism to ensure that the falling material is dispersed more evenly. Although this method improves the uniformity of the material to a certain extent, in actual use, in the early stage of feeding, even with the dispersion of multiple feeding holes on the feeding hopper, because the initial feeding material is small, most of it falls into the reaction liquid from the feeding holes below the discharge port of the conveying bin, which can still easily lead to the problem of excessively rapid local heating due to the concentrated feeding of material.

[0005] To address the aforementioned problems, this application proposes a chemical safety feeding device. Utility Model Content

[0006] This invention provides a chemical safety feeding device to solve the above-mentioned technical problems.

[0007] To solve the above-mentioned technical problems, this utility model provides a chemical safety feeding device, including a feeder, and a feeding mechanism is installed below the feeder's outlet;

[0008] The feeding mechanism includes an annular cylinder, inside which a material distribution plate is fixedly connected. The top of the material distribution plate has multiple material distribution holes that are wider at the top and narrower at the bottom. A pushing mechanism is installed above the material distribution plate, a sealing mechanism is installed below the material distribution plate, and a subdivision mechanism is installed below the sealing mechanism. A housing is fixedly connected to one side of the annular cylinder. Both the sealing mechanism and the subdivision mechanism are located inside the annular cylinder and extend into the housing.

[0009] Preferably, the sealing mechanism includes a baffle plate located at the bottom of the distribution plate and inside the annular cylinder extending into the housing. The top of the baffle plate has multiple through holes that are adapted to the bottom of the distribution hole. An electric push rod is fixedly connected to the inner wall of the housing, and the end of the piston rod of the electric push rod is fixedly connected to one side of the baffle plate.

[0010] Preferably, a through-hole is provided on one side of the annular cylinder, through which the baffle plate passes. A support ring is fixedly connected to the inner wall of the annular cylinder. The support ring is located at the top of the baffle plate and plays a supporting and limiting role for the baffle plate. Two positioning ribs are fixedly connected to the front and rear sides of the inside of the shell, respectively, and the baffle plate is located between two adjacent positioning ribs.

[0011] Preferably, the subdivision mechanism includes a screen plate, which is fixedly connected inside the annular cylinder. A motor is fixedly connected to the bottom of the housing.

The bottom of the push plates is in contact with the top of the distribution plate.

[0013] Compared with related technologies, the chemical safety feeding device provided by this utility model has the following beneficial effects:

[0014] When distributing materials through the combination of a feeder, a distribution plate, and the distribution holes on the distribution plate, the distribution holes can be blocked initially by a sealing mechanism. When the amount of material increases, the blockage can be released, and the material can be further distributed in conjunction with the pushing mechanism. After the initial distribution, the falling material can be further screened by a fine separation mechanism, so that the material falls more evenly into the reaction liquid for reaction. This ensures that the material is evenly distributed throughout the feeding process, effectively avoiding the problem of localized rapid heating caused by concentrated material feeding. It is very convenient and safer to use. Attached Figure Description

Detailed Implementation

[0020] Please see Figure 1-4 The technical solution provided by this utility model specifically includes the following embodiments:

[0021] A chemical safety feeding device includes a feeder 1, and a feeding mechanism is installed below the discharge port of the feeder 1;

[0022] The feeding mechanism includes an annular cylinder 2, inside which a material distribution plate 3 is fixedly connected. The top of the material distribution plate 3 has multiple material distribution holes 4 that are wider at the top and narrower at the bottom. A pushing mechanism is installed above the material distribution plate 3, and a sealing mechanism is installed below the material distribution plate 3. A subdivision mechanism is installed below the sealing mechanism. A housing 9 is fixedly connected to one side of the annular cylinder 2. The sealing mechanism and the subdivision mechanism are both located inside the annular cylinder 2 and extend into the housing 9.

[0023] The sealing mechanism includes a baffle plate 10, which is located at the bottom of the distribution plate 3 and extends into the housing 9 from inside the annular cylinder 2. The top of the baffle plate 10 has multiple through holes 11 that are adapted to the bottom of the distribution hole 4. An electric push rod 15 is fixedly connected to the inner wall of the housing 9, and the piston rod end of the electric push rod 15 is fixedly connected to one side of the baffle plate 10.

[0024] When there is little material on the distribution plate 3 in the early stage, the baffle plate 10 can be pulled by the electric push rod 15 to make the through hole 11 and the distribution hole 4 misaligned. At this time, the material cannot fall on the distribution plate 3. When there is more material, the baffle plate 10 can be moved by the electric push rod 15 to make the through hole 11 and the distribution hole 4 connected. With the continuous operation of the pushing mechanism, the material falling from the distribution plate 3 can be more even.

[0025] The annular cylinder 2 has a through-hole 13 on one side, through which the baffle plate 10 passes. A support ring 12 is fixedly connected to the inner wall of the annular cylinder 2. The support ring 12 is located at the top of the baffle plate 10 and plays a supporting and limiting role for the baffle plate 10. Two positioning ribs 14 are fixedly connected to the front and rear sides of the inside of the housing 9, and the baffle plate 10 is located between two adjacent positioning ribs 14.

[0026] The support ring 12 can support the baffle plate 10 so that it is always in close contact with the bottom of the distribution plate 3. When the baffle plate 10 moves, the positioning rib 14 can play a positioning and guiding role for the baffle plate 10.

[0027] The subdivision mechanism includes a screen plate 16, which is fixedly connected inside the annular cylinder 2. A motor 17 is fixedly connected to the bottom of the housing 9. The output shaft of the motor 17 passes through the annular cylinder 2 and extends into the annular cylinder 2. A shaped wheel 18 is fixedly connected to the output shaft of the motor 17, and the shaped wheel 18 is located below the screen plate 16.

[0028] When the screen plate 16 in the subdivision mechanism catches the dispersed falling material, the motor 17 drives the shaped wheel 18 to rotate and continuously strike the screen plate 16, so that the screen plate 16 can vibrate continuously to shake off the material above it. The material passing through the screen plate 16 can fall into the reaction liquid more evenly.

[0029] The pushing mechanism includes a mounting base 5, which is fixedly connected to the top of the inner end of the annular cylinder 2. A reduction motor 6 is fixedly connected to the center of the top of the mounting base 5. A shaft 7 is fixedly connected to the output shaft of the reduction motor 6. The end of the shaft 7 is movably connected to the center of the top of the distribution plate 3. A plurality of push plates 8 are fixedly connected to the outer end of the shaft 7. The bottom of the push plate 8 is in contact with the top of the distribution plate 3.

[0030] The pushing mechanism can push the material piled on the distribution plate 3 to spread it out, so that the material can fall through the distribution hole more evenly.

[0031] Working principle:

[0032] The feeder 1 feeds material onto the distribution plate 3 inside the annular cylinder 2. When the material falls onto the distribution plate 3, the baffle plate 10 is pulled to the right by the electric push rod 15, causing the through hole 11 to be misaligned with the distribution hole 4. Therefore, the bottom of the distribution hole 4 is blocked by the baffle plate 10, preventing the material from falling off the annular cylinder 2. During this time, the pushing mechanism continues to operate. When the material reaches a certain amount, the material accumulated on the distribution plate 3 is continuously pushed and evenly distributed on the distribution plate 3 by multiple push plates 8. Then, the through hole 11 is... The electric push rod 15 pushes the baffle plate 10 to connect the through hole 11 with the distribution hole 4. Then the material on the distribution plate 3 can be evenly dispersed and fall through the distribution hole 4 and the through hole 11. The falling material will fall onto the screen plate 16. During this period, the motor 17 continuously drives the shaped wheel 18 to rotate, so that the shaped wheel 18 quickly hits the screen plate 16, causing the screen plate 16 to vibrate continuously. Therefore, the material falling on the screen plate 16 is more evenly dispersed, and then falls into the reaction liquid to react.
