Description

Technical Field

[0001] This invention relates to a reaction feeding device, and more particularly to a chemical safety feeding device. Background Technology

[0002] In the process of chemical production, different raw materials are often put into a reaction vessel to carry out chemical reactions in order to prepare the desired products. There are many types of chemical reactions, and acid-base neutralization reaction is a common type. For example, the preparation of cryolite (Na3AlF6) is achieved by acid-base neutralization reaction of hydrofluoric acid (HF) with AlOH and NaOH.

[0003] In acid-base neutralization chemical reactions, an acidic solution is typically placed in a reaction vessel, and then basic powder is added to the vessel. Since acid-base neutralization is a relatively vigorous exothermic reaction, the reaction rate needs to be controlled. The basic powder cannot be added all at once, but must be added gradually. A negative pressure feeding method is generally used for adding basic powder. However, with this method, the basic powder added at one time tends to concentrate in the acidic solution, causing the reaction at that location to be too vigorous.

[0004] Furthermore, in the negative pressure feeding method, materials are generally added from the top of the reactor, away from the surface of the acidic solution. This causes the alkaline powder to directly impact the liquid surface and splash, making the reaction too violent. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides a chemical safety feeding device that adds alkaline powder by rotating conveyor blades. This allows for a continuous and gradual addition of alkaline powder, avoiding the violent reaction caused by adding too much at once. The rotation of the feeding cylinder ensures comprehensive addition of alkaline powder, preventing violent reactions caused by concentrated addition.

[0007] Furthermore, a support plate is fixed to the inner wall of the receiving cylinder, and a vertically upward disturbance rod is fixed to the upper surface of the support plate. The disturbance rod is made of elastic material, and the top of the disturbance rod is located above the support rod.

[0008] Furthermore, a first discharge pipe is sleeved on the outside of the feeding pipe, and a second discharge pipe is sleeved on the outside of the first discharge pipe.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Example 1

[0025] The present invention discloses a chemical safety feeding device, comprising a reactor 1, a hopper 2, a receiving cylinder 3, a servo motor 4, and a feeding cylinder 5. A first feeding pipe 11 is fixedly connected to the top of the reactor 1. The hopper 2 is fixedly connected to the top of the reactor 1, and a second feeding pipe 21 is fixedly connected to the top of the hopper 2. A discharge port 22 is provided on the top plate of the reactor 1 corresponding to the position of the hopper 2. A seat plate 23 is provided at the center of the discharge port 22, and the seat plate 23 is fixed inside the discharge port 22 by circumferentially evenly arranged support rods 24. The receiving cylinder 3 is rotatably connected to the lower surface of the top plate of the reactor 1. The vertical projection of the discharge port 22 is located inside the top opening of the receiving cylinder 3. A cover 41 is fixedly connected to the top of the hopper 2, and the servo motor 4 is fixedly connected inside the cover 41. The servo motor 4 has a vertically downward output shaft. 42. The output shaft 42 is rotatably connected to the top plate of the hopper 2. A vertically upward rotating shaft 43 is fixedly connected to the center of the bottom plate of the receiving cylinder 3. The rotating shaft 43 is rotatably connected to the seat plate 23, and the top of the rotating shaft 43 is connected to the bottom of the output shaft 42 through a coupling 44. A conveying pipe 51 is fixedly connected to the side plate of the receiving cylinder 3. The side plate of the feeding cylinder 5 is fixedly connected to the conveying pipe 51. A conveying shaft 52 is rotatably connected to the side of the feeding cylinder 5 away from the conveying pipe 51. A spiral conveying blade 53 is fixedly connected to the conveying shaft 52 inside the conveying pipe 51. A rolling bevel gear 54 is fixedly connected to the end of the conveying shaft 52 away from the receiving cylinder 3. A spiral bevel gear ring 55 is fixedly connected to the inner wall of the reactor 1. The rolling bevel gear 54 meshes with the spiral bevel gear. A feeding pipe 56 is fixedly connected to the bottom of the feeding cylinder 5.

[0026] The inner wall of the receiving cylinder 3 is fixedly connected to a support plate 31, and the upper surface of the support plate 31 is fixedly connected to a vertically upward disturbance rod 32. The disturbance rod 32 is made of elastic material, and the top of the disturbance rod 32 is located above the support rod 24.

[0027] In this embodiment:

[0028] like Figure 1-3 As shown, when the device is in use, the acidic solution is added to the reaction vessel 1 through the first adding pipe 11, and the alkaline powder is added to the hopper 2 through the second adding pipe 21. The alkaline powder enters the receiving cylinder 3 through the discharge port 22. The servo motor 4 is started, and the servo motor 4 drives the output shaft 42, the rotating shaft 43, the receiving cylinder 3, the conveying pipe 51 and the feeding cylinder 5 to rotate synchronously.

[0029] During the rotation of the receiving cylinder 3, the disturbance rod 32 is driven to rotate. The disturbance rod 32 disturbs the alkaline powder at the discharge port 22 to prevent blockage, so that the alkaline powder can smoothly enter the receiving cylinder 3.

[0030] When the conveying pipe 51 and the feeding cylinder 5 rotate, under the action of the spiral bevel gear ring 55, the rolling bevel gear 54, the conveying shaft 52 and the conveying blade 53 rotate. The conveying blade 53 can input the alkaline powder in the receiving cylinder 3 into the feeding cylinder 5 through the conveying pipe 51. The alkaline powder falls from the feeding pipe 56, thereby realizing the feeding of alkaline powder. The addition of alkaline powder is realized by the rotation of the spiral blade, which can make the addition process continuous and slow, avoiding the violent reaction caused by adding too much at once.

[0031] The alkaline powder is added comprehensively by rotating the feed cylinder 5, avoiding the violent reaction caused by concentrated addition.

[0032] Example 2

[0033] The feed pipe 56 mentioned in this invention is fitted with a first discharge pipe 61, and a second discharge pipe 62 is fitted with the first discharge pipe 61. The outer circumference of the first discharge pipe 61 is uniformly provided with lifting grooves 63. The inner wall of the second discharge pipe 62 is fixedly connected with a lifting block 64 that is adapted to the lifting groove 63. The bottom circumference of the second discharge pipe 62 is uniformly fixedly connected with connecting rods 65, and the bottom of each connecting rod 65 is integrally fixedly connected with a float 66.

[0034] Preferably, a conical guide seat 67 is fixed to the upper surface of the float 66.

[0035] In this embodiment:

[0036] The alkaline powder is fed sequentially through the feed pipe 56, the first discharge pipe 61, and the second discharge pipe 62. Since the float 66 always floats on the surface of the acidic solution, the alkaline powder falls onto the guide seat 67, slides down, and then falls onto the acidic solution, making the feeding position close to the surface of the acidic solution, which can reduce the splashing of the solution.

[0037] Example 3

[0038] The feed pipe 56 mentioned in this invention has an annular groove 68 on its outer wall. The inner wall of the first discharge pipe 61 is fixedly connected to an annular slider 69. The first discharge pipe 61 is rotatably connected to the feed pipe 56 through the cooperation of the slider 69 and the groove 68. The outside of the first discharge pipe 61 is also fixedly connected to a drive gear 610. The inner wall of the reactor 1 is fixedly connected to a drive gear ring 612 through a mounting rod 611 evenly arranged around the circumference. The drive gear 610 meshes with the inner ring of the drive gear ring 612.

[0039] Preferably, the bottom of the float 66 is fixedly connected to a stirring shaft 613, and the stirring shaft 613 is densely covered with stirring blades 614.

[0040] In this embodiment:

[0041] During the rotation of the feed cylinder 5, the first discharge pipe 61 is driven to revolve. With the cooperation of the drive gear 610 and the drive gear ring 612, the first discharge pipe 61, the second discharge pipe 62 and the float 66 are rotated.

[0042] Under the action of centrifugal force, the alkaline powder on the feed seat 67 is circumferentially scattered, thereby further dispersing the feeding position.

[0043] Simultaneously, a stirring shaft 613 and stirring blades 614 are provided to stir the acidic solution, thereby making the mixing of alkaline powder and acidic solution more uniform and the reaction more effective.

[0044] Example 4

[0045] The reactor 1 mentioned in this invention has a transparent observation window 45 fixed to one side.

[0046] Preferably, the servo motor 4 is powered by an external power source and is equipped with a rotary switch 46 for controlling its start / stop and speed. The rotary switch 46 is fixed to the top of the hopper 2.

[0047] In this embodiment:

[0048] The reaction in the reactor 1 can be observed through the observation window 45. When the reaction is vigorous, the speed of the servo motor 4 can be reduced by the knob switch 46. Conversely, when the reaction is too slow, the speed of the servo motor 4 can be increased.

[0049] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
