Description

Technical Field

[0001] This utility model relates to the field of material processing equipment, and in particular to an anti-clogging mechanism for a reactor discharge valve. Background Technology

[0002] A reaction vessel is a container used for chemical reactions, physical changes, or synthesis, commonly used in industrial production. In a reaction vessel, raw materials undergo a chemical reaction under specific conditions of temperature, pressure, and agitation to generate new chemical substances. It is typically made of corrosion-resistant materials such as stainless steel, glass, and alloys to hold the reactants and withstand the high temperatures and pressures generated during the reaction. Ensuring sufficient contact between the reactants promotes the reaction. There are many types of agitators, such as paddle, anchor, and spiral agitators. Because many reactions require specific temperatures, reaction vessels are equipped with heating and cooling systems to regulate the reaction temperature. Common heating methods include electric heating and steam heating. Some chemical reactions require high pressure, and the reaction vessel may need a pressure control system to maintain the required pressure range.

[0003] However, existing equipment often encounters the following problems during use:

[0004] In traditional reactors, viscous materials tend to accumulate around the valve discs during the discharge process, leading to blockages and affecting discharge efficiency and normal equipment operation. Utility Model Content

[0005] The main purpose of this invention is to provide an anti-clogging mechanism for the discharge valve of a reactor, which effectively solves the problem mentioned in the background art that viscous materials tend to accumulate around the valve disc during the discharge process, causing blockage and affecting the discharge efficiency and normal operation of the equipment. This invention seals the valve disc when the air bladder is inflated to ensure that the material does not leak. During the flipping process, the flipping action of the valve disc and the expansion toughness of the air bladder can effectively prevent viscous materials from accumulating at the edge of the valve disc, ensuring that the material is discharged smoothly.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A reaction vessel discharge valve anti-clogging mechanism includes:

[0008] The main discharge pipe body is placed vertically.

[0009] An annular recess is provided on the inner wall of the main discharge pipe;

[0010] A valve disc, which is horizontally placed on the inner wall of the main discharge pipe;

[0011] An annular airbag covers the outer periphery of the valve disc. Under normal conditions, the annular airbag inflates to seal the annular recess.

[0012] A flipping rod, one end of which is connected to the valve disc, is a hollow rod. The valve disc can rotate horizontally to vertically with the flipping rod. The flipping rod passes through the main discharge pipe and extends to the outside of the main discharge pipe.

[0013] The air tube is built into the inner wall of the flipping rod, one end of the air tube is connected to the annular airbag, and the other end of the air tube is connected to the central shaft of the flipping gear.

[0014] The flipping gear is located at the end of the flipping rod away from the main discharge tube;

[0015] Valve core, which is embedded in the central shaft of the reversing gear.

[0016] Also includes:

[0017] A feeding motor is installed on the body of the main feeding pipe.

[0018] A drive belt, one end of which is fitted onto the output end of the feeding motor;

[0019] A supporting housing, which is fixedly connected to the body of the main discharge pipe;

[0020] A top rotating shaft wheel is located inside the bearing housing, and the top rotating shaft wheel is connected to the output end of the feeding motor via the transmission belt;

[0021] A bottom rotating shaft wheel is located below the top rotating shaft wheel, and the axis of the bottom rotating shaft wheel is movably connected to the interior of the bearing housing;

[0022] A rotating shaft rod, wherein the rotating shaft rod is arranged longitudinally, and both ends of the rotating shaft rod are coaxially connected to the top rotating shaft wheel and the bottom rotating shaft wheel;

[0023] The meshing teeth are located on the edge of the bottom rotating shaft wheel. Multiple meshing teeth are arranged adjacently. When the annular airbag deflates and contracts, the meshing teeth trigger the flipping gear once per revolution, causing the valve disc to flip from the horizontal sealing position to the vertical material discharge position.

[0024] An auxiliary feeding branch pipe is provided, which is obliquely arranged and is connected to the main feeding pipe.

[0025] The bottom rotating wheel has five equally spaced meshing teeth on its edge, with a tooth pitch ratio of 1:1 between each meshing tooth.

[0026] The drive belt is controlled by a tensioner.

[0027] The annular airbag is made of high-temperature resistant silicone material.

[0028] The valve disc is circular, and when the valve disc is in the vertical discharge position, its edge forms a double-sided pouring channel with the inner wall of the main discharge pipe.

[0029] The valve core is connected to the air pipe.

[0030] Compared with the prior art, the beneficial effects of this utility model are: the annular airbag and valve flap flipping mechanism in this utility model effectively solve the problem of viscous substances. When the airbag is inflated, it seals the valve flap to ensure that the material does not leak, and the expansion toughness of the airbag can effectively prevent viscous substances from accumulating around and at the edges of the valve flap. Compared with the traditional lifting and blocking and discharging, the flipping discharging ensures that the material is released smoothly. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] like Figure 1-4 As shown, this utility model provides an anti-clogging mechanism for the discharge valve of a reactor. The anti-clogging mechanism for the discharge valve of the reactor includes a main discharge pipe body 1, an annular recess 2, a valve disc 3, an annular air bladder 4, a flipping rod 5, an air pipe 6, a flipping gear 7, and an air valve core 8.

[0040] The main discharge pipe 1 is placed vertically. The inner wall of the main discharge pipe 1 has an annular recess 2. The vertical design of the main discharge pipe 1 facilitates the smooth flow of material through the pouring channel of the valve disc 3. The annular recess 2 is located on the inner wall of the pipe, primarily to form a sealing fit with the outer periphery of the annular airbag 4, preventing material leakage. The valve disc 3 is placed horizontally on the inner wall of the main discharge pipe 1. The valve disc 3 is circular. When in the vertical discharge position, its edge forms a double-sided pouring channel with the inner wall of the main discharge pipe 1. The valve disc 3 is designed to be circular and can be rotated from horizontal to vertical, its function being to control the flow of material. The design of the valve disc 3, where its edge forms a pouring channel with the inner wall of the main discharge pipe 1, effectively guides the material outflow, making it particularly suitable for discharging viscous materials.

[0041] In this invention, an annular airbag 4 covers the outer periphery of the valve disc 3. Under normal conditions, the annular airbag 4 inflates to seal the annular recess 2. The annular airbag 4, covering the outer periphery of the valve disc 3 and normally inflated, primarily functions to seal the annular recess 2. When the annular airbag 4 is inflated, it ensures that the valve disc 3 is in a closed state, preventing material leakage or blockage. The annular airbag 4 is made of high-temperature resistant silicone, capable of meeting the requirements of operation in high-temperature environments.

[0042] In this invention, one end of the flipping rod 5 is connected to the valve disc 3. The flipping rod 5 is a hollow rod, and the valve disc 3 can rotate horizontally to vertically with the flipping rod 5. The flipping rod 5 passes through the main discharge pipe 1 and extends to the outside of the main discharge pipe 1. The flipping rod 5 is used to drive the valve disc 3 to rotate. It is designed as a hollow rod, and the flipping rod 5 enables the valve disc 3 to rotate from a horizontal position to a vertical discharge position. This design can ensure that the material can be discharged smoothly in viscous conditions.

[0043] In this invention, the air pipe 6 is built into the inner wall of the flipping rod 5. One end of the air pipe 6 is connected to the annular air bladder 4, and the other end is connected to the central shaft of the flipping gear 7. The air pipe 6 is built into the flipping rod 5 and connected to the annular air bladder 4. The inflation and deflation of the annular air bladder 4 are controlled by the cooperation of the air pipe 6 and the valve core 8. The design of the valve core 8 allows the annular air bladder 4 to be inflated or deflated in a timely manner, thereby controlling the sealing or discharging state of the valve disc 3. The flipping gear 7 is located at the end of the flipping rod 5 away from the main discharge pipe 1. The flipping gear 7 is connected to the flipping rod 5 through the operation of the valve core 8, driving the valve disc 3 to flip from the sealing state to the discharging state. The meshing teeth 15 interact with the flipping gear 7 to ensure precise control and smooth operation during the flipping process of the valve disc 3. In particular, the design of the meshing teeth 15 allows the flipping of the valve disc 3 to be driven by the deflation process of the material, which can avoid errors caused by human control. The valve core 8 is embedded in the central shaft of the flipping gear 7. The valve core 8 is connected to the air pipe 6.

[0044] In this invention, the feeding motor 9 is installed on the body of the main feeding pipe 1. The feeding motor 9 and the transmission belt 10 work together, with the transmission belt 10 driving the bottom rotating shaft 13 to rotate via the top rotating shaft 12. This design allows the material feeding process to be completed mechanically, providing efficient power output and ensuring the stability and continuity of the material feeding process. One end of the transmission belt 10 is sleeved on the output end of the feeding motor 9; the transmission belt 10 is controlled by a tensioning pulley. The supporting housing 11 is fixedly connected to the body of the main feeding pipe 1, providing support for the system and enabling components such as the top rotating shaft 12 and the bottom rotating shaft 13 to operate stably. The top rotating shaft 12 and the bottom rotating shaft 13 are connected by a rotating shaft 14, forming a complete power transmission structure. This design ensures the stability and durability of the transmission system. The top rotating shaft wheel 12 is located inside the bearing housing 11 and is connected to the output end of the feeding motor 9 via the transmission belt 10. The bottom rotating shaft wheel 13 is located below the top rotating shaft wheel 12 and its axis is movably connected to the interior of the bearing housing 11. The bottom rotating shaft wheel 13 has five equally angled meshing teeth 15 on its edge, and the tooth pitch ratio of each adjacent meshing tooth 15 is 1:1.

[0045] In this invention, the rotating shaft 14 is longitudinally arranged, and its two ends are coaxially connected to the top rotating shaft wheel 12 and the bottom rotating shaft wheel 13. Engaging teeth 15 are located on the edge of the bottom rotating shaft wheel 13, and multiple engaging teeth 15 are arranged adjacently. When the annular airbag 4 deflates and contracts, the engaging teeth 15 trigger the flipping gear 7 once per revolution, causing the valve disc 3 to flip from the horizontal sealing position to the vertical discharge position. The auxiliary discharge branch pipe 16 is obliquely arranged and communicates with the main discharge pipe body 1. The oblique design of the auxiliary discharge branch pipe 16 aims to provide a second flow channel for the material, ensuring smooth discharge after the valve disc 3 flips, and avoiding blockage caused by excessively high material viscosity. When the annular airbag 4 is inflated or deflated through the valve core 8, its outer surface forms a dynamic interference fit seal with the annular recess 2.

[0046] It should be noted that, in the anti-clogging mechanism of the reactor discharge valve designed in this utility model, when a viscous material needs to be discharged, the valve core 8 is pulled out. After the valve core 8 on the central shaft of the rotating gear 7 is pulled out, the annular air bladder 4 around the valve disc 3 gradually deflates and contracts. Since the annular recess 2 on the inner diameter pipe wall of the main discharge pipe 1 is filled and sealed by the annular air bladder 4 around the valve disc 3, once the annular recess 2 loses its filling by the annular air bladder 4, some viscous material will slowly flow out from the gap around the valve disc 3. At this time, the discharge motor 9 is started, and the output end of the motor rotates, driving the transmission belt 10. The transmission belt 10 drives the top rotating shaft wheel 12, and the top rotating shaft wheel 12 rotates, driving the bottom rotating shaft wheel 13 below through the rotating shaft rod 14. The wheel 13 has a few meshing teeth 15 arranged vertically on its edge. After rotating for nearly one revolution, these meshing teeth 15 come into contact with the flipping gear 7. The flipping gear 7 rotates and drives the flipping rod 5 on one side. The flipping rod 5 rotates axially and drives the circular valve 3 that blocks the material to flip from horizontal to vertical. The viscous material will be unblocked and will pour out through both sides of the valve 3. Finally, the material is discharged through the auxiliary discharge branch pipe 16. Since the outer periphery of the valve 3 is a contracted annular air bladder 4, the viscous material will adhere to the outer surface of the contracted annular air bladder 4 during the discharge process. When used for the second time, the valve 3 returns to the horizontal position. After the annular air bladder 4 is swollen and refilled by the valve core 8, it can still be sealed. It will not be blocked by the adhesion of viscous material and will not be unable to be used normally.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
