Description

Technical Field

[0001] The utility model belongs to the technical field of reactors, and particularly relates to a feeding device for a reactor. Background Art

[0002] In many areas of modern industry, such as chemical engineering, pharmaceuticals, and food processing, reactors are core equipment for chemical reactions or physical processes, and their performance and efficiency have a crucial impact on production outcomes. The dosing device, an indispensable component of the reactor, undertakes the critical task of accurately and efficiently feeding raw materials into the reactor.

[0003] Traditional reactor dosing operations present a series of pressing challenges. Regarding quantitative dosing, due to the lack of precise control methods and effective measurement mechanisms, operators often rely on subjective experience and rough estimates. This approach not only introduces significant errors, making it difficult to achieve precise dosing requirements, but also severely impacts the chemical composition and process stability of the reaction due to inconsistent dosing amounts. This can lead to inconsistent product quality, failing to meet high-standard production requirements, while also causing unnecessary waste of raw materials and increasing production costs.

[0004] The problem of material adhesion is also prominent. During the feeding process, due to the physical and chemical properties of the materials, they are very easy to adhere to the inner walls, corners and various contact surfaces of the feeding device. As the number of feeding times increases, the adhered materials continue to accumulate. This not only occupies the effective feeding space and reduces the actual feeding amount, thereby affecting the normal progress of the reaction, but may also cause the materials to deteriorate, agglomerate and other adverse changes due to long-term retention, thereby affecting the effect of subsequent reactions and product quality. In addition, the cleaning of adhered materials is difficult, requiring a lot of manpower and time for maintenance, increasing production complexity and downtime.

[0005] To this end, we proposed a feeding device for a reactor, which can not only achieve the effect of quantitative feeding, but also prevent the material from sticking. Utility Model Content

[0006] The purpose of the present invention is to provide a feeding device for a reactor, which can not only achieve the effect of quantitative feeding, but also prevent the material from sticking.

[0007] The technical solutions adopted in this application are as follows:

[0008] A feeding device for a reactor comprises a reactor body, wherein a feeding assembly is provided on the top of the reactor body;

[0009] The feeding assembly includes a first feeding shell connected to the reactor body, a cylindrical hollow shell is installed on the top of the first feeding shell, a rotating assembly is provided on the cylindrical hollow shell, and a rotating disk is provided on the rotating assembly located inside the cylindrical hollow shell. Two symmetrical arc surfaces and two symmetrical planes are provided on the outer side of the rotating disk, and the two symmetrical arc surfaces are both fitted with and slid on the inner wall of the cylindrical hollow shell. A rectangular groove located on the rotating disk is opened on the two symmetrical planes, and four elastic components are provided on the inner wall of the bottom of the rectangular groove. The four elastic components are provided with sliding plates that fit with and slide on the inner wall of the rectangular groove, and a material receiving shell connected to the cylindrical hollow shell is provided on the top.

[0010] Furthermore, the rotating assembly includes a motor disposed on the cylindrical hollow shell, and an output end of the motor is connected to the rotating disk.

[0011] Furthermore, a sealing layer is provided on the two arc-shaped surfaces.

[0012] Furthermore, the elastic component includes four through holes opened on the sliding plate, and a movable rod is provided inside each through hole. The bottom of the movable rod is connected to the inner wall of the bottom of the rectangular groove, and a limiting plate is provided on the top of the movable rod. A spring is provided on the movable rod, and the spring is located between the sliding plate and the inner wall of the rectangular groove.

[0013] Furthermore, scrapers are provided on both sides of the top of the sliding plate, and the scrapers are in contact with the inner wall of the rectangular groove.

[0014] Furthermore, the feed opening of the material receiving shell is smaller than the cross-sectional area of the rectangular groove.

[0015] The technical effects achieved by this utility model are:

[0016] When feeding, the two arc-shaped surfaces on the rotating disk fit with the inner wall of the cylindrical hollow shell, and the rectangular grooves on the two planes correspond to the first feeding shell and the receiving shell respectively. Then, the external material enters the cylindrical hollow shell through the receiving shell. Because the top rectangular groove corresponds to the receiving shell, the material directly enters the top rectangular groove. The weight on the sliding plate inside the top rectangular groove becomes heavier, so that the sliding plate moves downward on the inner wall of the rectangular groove and squeezes the elastic component. When the material reaches the required amount, the cylindrical hollow shell is driven to rotate by the rotating component. During the rotation, the two arc-shaped surfaces seal the receiving shell to prevent material leakage. At the same time, the rectangular groove filled with material rotates to the position of the first feeding shell. At this time, the material enters the first feeding shell from the inside of the rectangular groove by gravity. Due to the weight reduction and the effect of gravity, the sliding plate moves inside the rectangular groove, thereby clearing the material adhering to the inner wall of the rectangular groove to prevent the material from adhering. The feeding is repeated in sequence. The device can not only achieve the effect of quantitative feeding, but also prevent the material from adhering. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0024] like Figure 1-4As shown, the technical solution adopted by the present invention is as follows: a feeding device for a reactor, comprising a reactor body 1, a feeding assembly is provided on the top of the reactor body 1;

[0025] The feeding assembly includes a first feeding shell 2 connected to the reactor body 1, a cylindrical hollow shell 3 is installed on the top of the first feeding shell 2, a rotating assembly is provided on the cylindrical hollow shell 3, and a rotating disk 4 is provided on the rotating assembly located inside the cylindrical hollow shell 3. Two symmetrical arc surfaces 5 and two symmetrical planes 6 are provided on the outside of the rotating disk 4. The two symmetrical arc surfaces 5 both fit and slide with the inner wall of the cylindrical hollow shell 3. Rectangular grooves 7 located on the rotating disk 4 are opened at the positions of the two symmetrical planes 6. Four elastic components are provided on the inner wall of the bottom of the rectangular groove 7. The four elastic components are provided with sliding plates 8 that fit and slide with the inner wall of the rectangular groove 7, and a material receiving shell 9 connected to it is provided on the top of the cylindrical hollow shell 3.

[0026] The rotating assembly includes a motor 10 provided on the cylindrical hollow shell 3, and the output end of the motor 10 is connected to the rotating disk 4. The rotating disk 4 is driven to rotate by the motor 10, thereby achieving feeding.

[0027] At the same time, a sealing layer is provided on the two arc-shaped surfaces 5 , and the material receiving shell 9 can be sealed by the sealing layer to prevent material leakage.

[0028] like Figure 4 As shown, the elastic component includes four through holes opened on the sliding plate 8, and a movable rod 11 is arranged inside each through hole. The bottom of the movable rod 11 is connected to the bottom inner wall of the rectangular groove 7, and a limiting disk is arranged on the top of the movable rod 11. A spring 12 is sleeved on the movable rod 11, and the spring 12 is located between the sliding plate 8 and the inner wall of the rectangular groove 7.

[0029] When the sliding plate 8 is subjected to gravity, the sliding plate 8 moves on the movable rod 11 through the through hole, thereby squeezing the spring 12. When the rectangular slot 7 rotates to the position of the first feed shell 2, the sliding plate 8 returns to its original position under the influence of gravity and the elastic force of the spring 12, allowing the material to be discharged.

[0030] Scrapers 13 are provided on both sides of the top of the sliding plate 8. The scrapers 13 are in contact with the inner wall of the rectangular groove 7. The scrapers 13 can scrape off the material adhered to the inner wall of the rectangular groove 7 to prevent clogging.

[0031] The feed opening of the material receiving housing 9 is smaller than the cross-sectional area of the rectangular groove 7. This arrangement enables the material entering the material receiving housing 9 to directly enter the rectangular groove 7 without causing material leakage.

[0032] It should be noted that there is a certain cavity between the two planes 6 and the cylindrical hollow shell 3. The area of this cavity can be set. The setting method is the height of the plane 6 opened on the rotating disk 4. This cavity will not affect the discharge of the material. Even if the material enters the cavity, the rotation of the rotating disk 4 will drive the material in the cavity to move, which will not affect the discharge of the material.

[0033] The working principle of this utility model is: when feeding, if Figure 2 As shown, at this time, the two arc-shaped surfaces 5 on the rotating disk 4 are fitted with the inner wall of the cylindrical hollow shell 3, and the rectangular grooves 7 on the two planes 6 correspond to the first feeding shell 2 and the receiving shell 9 respectively. Then, the external material enters the cylindrical hollow shell 3 through the receiving shell 9. Because the top rectangular groove 7 corresponds to the receiving shell 9, the material directly enters the top rectangular groove 7. The weight on the sliding plate 8 inside the top rectangular groove 7 becomes heavier, so that the sliding plate 8 moves downward on the inner wall of the rectangular groove 7 and squeezes the elastic component. When the material reaches the required When measuring, the cylindrical hollow shell 3 is rotated by the rotating assembly. During the rotation, the two arc-shaped surfaces 5 seal the material-jointing shell 9 to prevent material leakage. At the same time, the rectangular trough 7 filled with material rotates to the position of the first feed shell 2. At this time, the material enters the first feed shell 2 from the inside of the rectangular trough 7 by gravity. Due to the weight reduction and the effect of gravity, the sliding plate 8 moves inside the rectangular trough 7, thereby clearing the material adhering to the inner wall of the rectangular trough 7 to prevent the material from adhering. The feeding is repeated in this reciprocating manner. This device can not only achieve the effect of quantitative feeding, but also prevent the material from adhering.

[0034] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
