Description

Technical Field

[0001] This patent relates to the field of ethyl cellulose production technology, specifically to an anti-agglomeration ethyl cellulose reactor. Background Technology

[0002] Ethyl cellulose is a high molecular weight compound that is a white or light brown powder at room temperature. Ethyl cellulose is an ethyl ether of cellulose and is a long-chain polymer with β-dehydrated glucose units linked by acetal. It is one of the most widely used water-insoluble cellulose derivatives.

[0003] In industrial production, ethyl cellulose needs to be dissolved. The existing method is to use a reactor with a stirring shaft for stirring and dissolving. However, during the stirring and dissolving process, ethyl cellulose tends to clump together when it comes into contact with the solution, which prevents it from making full contact with the solution and results in poor dissolution efficiency.

[0004] Therefore, an ethyl cellulose reactor that prevents clumping is needed. Summary of the Invention

[0005] The purpose of this patent is to provide an anti-agglomeration ethyl cellulose reactor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this patent provides the following technical solution: an anti-agglomeration ethyl cellulose reactor, comprising a reactor body, a cover installed on the upper wall of the reactor body, a stirring mechanism installed on the upper wall of the cover, and the stirring mechanism being inserted into the reactor body through the lower wall of the cover.

[0007] An electrically controlled push rod is installed on the upper wall of the cover. The output end of the electrically controlled push rod passes through the lower wall of the cover and is inserted into the main body of the reactor. There are two electrically controlled push rods. A fixing ring is installed on the output end of the two electrically controlled push rods. A filter plate is installed on the inner side of the fixing ring. A rolling roller is installed on the side wall of the stirring mechanism. The rolling roller can fit against the upper wall of the filter plate.

[0008] Preferably, the stirring mechanism includes a motor frame, a motor, a stirring shaft, and stirring blades. The motor frame is installed on the upper wall of the cover, the motor is installed on the side wall of the motor frame, the motor is electrically connected to an external power source, the output end of the motor is installed through the lower wall of the cover, and stirring blades are installed on the side wall of the stirring shaft.

[0009] Preferably, the stirring shaft includes a connecting cylinder, a sleeve, and a sliding rod. The connecting cylinder is installed on the upper wall of the sleeve and is sleeved on the outside of the motor output end. The sliding rod is slidably installed inside the sleeve, and the stirring blade is installed on the outside of the sliding rod.

[0010] Preferably, the rolling roller includes a connecting shaft and a rotating ring. The connecting shaft is installed on the side wall of the stirring shaft, and the rotating ring is sleeved on the outside of the connecting shaft, allowing the rotating ring to rotate on the outside of the connecting shaft.

[0011] Preferably, a spring is installed in the inner cavity of the sleeve, and the lower wall of the spring is in contact with one end of the sliding rod located inside the sleeve.

[0012] Preferably, a sealing ring is fitted to the inner wall of the reactor body, and the sealing ring can fit against the inner wall of the cover.

[0013] Compared with existing technologies, the beneficial effects of this patent are:

[0014] When dissolving ethyl cellulose, this device can use an electrically controlled push rod to move the fixed ring and filter plate upwards, thereby scooping out the clumps of ethyl cellulose in the solution inside the reactor. During the upward movement, the crushing roller in the stirring mechanism will come into contact with the filter plate, so that the stirring mechanism, while rotating, will crush the clumps of ethyl cellulose on the filter plate through the crushing roller, thereby improving the dissolution efficiency.

Detailed Implementation

[0019] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] Please see Figure 1-3This patent provides a technical solution: an anti-agglomeration ethyl cellulose reactor, including a reactor body 1, a cover 2 installed on the upper wall of the reactor body 1, a stirring mechanism 3 installed on the upper wall of the cover 2, and the stirring mechanism 3 is inserted into the reactor body 1 through the lower wall of the cover 2.

[0021] When dissolving ethyl cellulose, the solution and ethyl cellulose need to be injected into the reactor body 1 first. Then, by starting the motor 32 in the stirring mechanism 3, the stirring shaft 33 and the stirring blade 34 are driven to rotate, thereby mixing the ethyl cellulose and the solution in the reactor body 1. The solution is an organic solvent, such as resin, wax and plasticizer.

[0022] An electric push rod 4 is installed on the upper wall of the cover 2. The output end of the electric push rod 4 passes through the lower wall of the cover 2 and is inserted into the reactor body 1. There are two electric push rods 4. The output ends of the two electric push rods 4 are equipped with fixing rings 5. Filter plates 6 are installed on the inner side of the fixing rings 5. A rolling roller 7 is installed on the side wall of the stirring mechanism 3. The rolling roller 7 can fit against the upper wall of the filter plate 6.

[0023] To avoid ethyl cellulose clumping during mixing, which would result in low mixing efficiency, this device incorporates an electrically controlled push rod 4 on its cover 2. This push rod 4 moves the fixing ring 5 and filter plate 6 inside the reactor body 1 upwards, allowing the clumped ethyl cellulose in the solution to be removed. During this removal process, the crushing roller 7 below the stirring mechanism 3 comes into contact with the filter plate 6. Simultaneously, the motor 32 continues to rotate the stirring shaft 33, causing it to crush the clumped ethyl cellulose through the crushing roller 7, thereby improving the mixing efficiency of ethyl cellulose and the organic solvent.

[0024] Specifically, the stirring mechanism 3 includes a motor frame 31, a motor 32, a stirring shaft 33, and a stirring blade 34. The motor frame 31 is installed on the upper wall of the cover 2, the motor 32 is installed on the side wall of the motor frame 31, the motor 32 is electrically connected to an external power source, the output end of the motor 32 is installed through the lower wall of the cover 2 and the stirring shaft 33 is installed thereon, and the stirring blade 34 is installed on the side wall of the stirring shaft 33.

[0025] Specifically, the stirring shaft 33 includes a connecting cylinder 331, a sleeve 332 and a sliding rod 333. The connecting cylinder 331 is installed on the upper wall of the sleeve 332. The connecting cylinder 331 is sleeved on the outside of the output end of the motor 32. The sliding rod 333 is slidably installed inside the sleeve 332. The stirring blade 34 is installed on the outside of the sliding rod 333.

[0026] In this paper, the cross-sections of the sliding rod 333 and the tower 332 are both square, so as to prevent the sliding rod 333 from rotating together with the sleeve 332 when the motor 32 drives the stirring shaft 33 to rotate.

[0027] Furthermore, during the upward movement of the fixed ring 5 and the filter plate 6, the sliding rod 333 can retract into the sleeve 332 under the pushing action of the filter plate 6, thus avoiding interference with the movement of the fixed ring 5 and the filter plate 6.

[0028] Specifically, the rolling roller 7 includes a connecting shaft 71 and a rotating ring 72. The connecting shaft 71 is installed on the side wall of the stirring shaft 33, and the rotating ring 72 is sleeved on the outside of the connecting shaft 71. The rotating ring 72 can rotate on the outside of the connecting shaft 71.

[0029] The roller 7 proposed in this paper is located below the agitator blade 34 to avoid the agitator blade 34 from contacting the filter plate 6, which would cause the filter plate 6 to be scratched and affect the filtration of agglomerated ethyl cellulose.

[0030] Specifically, a spring 8 is installed in the inner cavity of the sleeve 332, and the lower wall of the spring 8 is in contact with one end of the sliding rod 333 located inside the sleeve 332;

[0031] By providing a spring 8 inside its sleeve 332, a downward thrust can be provided to the sliding rod 333, thereby enabling the rolling roller 7 to fit more tightly against the filter plate 6 when the rolling roller 7 is in contact with the filter plate 6.

[0032] Specifically, a sealing ring 9 is fitted to the inner wall of the reactor body 1, and the sealing ring 9 can fit against the inner wall of the cover 2.

[0033] Working principle: First, the solution and ethyl cellulose are injected into the reactor body 1. Then, the motor 32 in the stirring mechanism 3 is started, which drives the stirring shaft 33 and the stirring blade 34 to rotate, thereby mixing the ethyl cellulose and the solution in the reactor body 1. In order to avoid the ethyl cellulose from clumping together during the mixing process, which would result in low mixing efficiency, the device is equipped with an electrically controlled push rod 4 on its cover 2, which can drive the fixing ring 5 and the filter plate 6 in the reactor body 1 to move upward, so that the clumped ethyl cellulose in the solution can be scooped out. During the scooping process, the crushing roller 7 below the stirring mechanism 3 will come into contact with the filter plate 6. At the same time, the motor 32 will continue to drive the stirring shaft 33 to rotate, so that it will crush the clumped ethyl cellulose through the crushing roller 7, thereby improving the mixing efficiency of ethyl cellulose and organic solvent.

[0034] It will be apparent to those skilled in the art that this patent is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this patent. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this patent is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this patent. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
