[0002] A sealing diaphragm is a key functional component that achieves sealing and media isolation through elastic deformation. Its core function is to separate the drive mechanism from the media to avoid corrosion or contamination. At the same time, it completes fluid transportation or flow control through physical deformation. During the production of sealing diaphragms, various sealing diaphragm raw materials are generally mixed and stirred by a mixing device.

[0003] Existing diaphragm material mixing devices typically use a stirring rod to mix the diaphragm material. However, due to the limited mixing range of the stirring rod, some materials may remain in dead zones and not participate in the mixing process, thus affecting the mixing effect of the diaphragm material.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] See also Figures 1-3 As shown, according to an embodiment of the present invention, a raw material mixing device for the production of sealing diaphragm sheets is provided, including: a storage cylinder 1, the bottom of which is hemispherical, a guide pipe 2 is provided at the axial position of which, and an air injection mechanism 3 is provided at the bottom end of the storage cylinder 1 for injecting air into the guide pipe 2.

[0032] A conical block 4 is positioned above the feed tube 2, with its sharp end inserted into the top opening of the feed tube 2.

[0033] The exhaust mechanism 5 is located at the top of the storage cylinder 1 and is used to exhaust the gas at the top of the storage cylinder 1.

[0034] The filter mechanism 6 is located below the exhaust mechanism 5 and is used to filter harmful substances in the gas and heat the gas before introducing it into the gas injection mechanism 3.

[0035] In this embodiment, when using the improved sealing diaphragm raw material mixing device, please refer to... Figure 1 and Figure 2 As shown, when the exhaust mechanism 5 is activated, airflow is continuously injected into the feed pipe 2. Due to the obstruction of a large amount of raw material on the outer periphery of the feed pipe 2 and the inertia of the airflow itself, almost all the gas flows upward along the feed pipe 2 and is discharged from the top opening of the feed pipe 2. Then, the airflow discharged from the top opening of the feed pipe 2 diffuses to the surroundings and is discharged out of the storage cylinder 1 by the exhaust mechanism 5. Then, the airflow flows into the filter mechanism 6 to filter out harmful substances in the gas (such as dust particles or odors) and heats the gas to a suitable temperature. Then, it is reintroduced into the gas injection mechanism 3 to form an internal gas circulation in the device and keep the raw material in the storage cylinder 1 in a high-temperature environment for a long time, so that the odor in the raw material can be quickly dissipated. During the mixing and stirring of the raw material, the odor and dust and other harmful substances in the raw material are removed to avoid the release of odor and dust and other harmful substances to the outside during the mixing and stirring of the raw material or when it slides out of the storage cylinder 1, which would affect the health of the workers.

[0036] Please refer to Figure 2 and Figure 3 As shown, after the gas internal circulation is formed, the gas flow rate in the guide pipe 2 is relatively fast, so a pressure difference is formed in the guide pipe 2. Combined with the pressure of the raw material at the top of the storage cylinder on the raw material at the bottom of the storage cylinder 1, some of the raw material in the storage cylinder slides into the guide pipe along the inner arc wall at the bottom of the storage cylinder. It is then carried by the airflow and moves upward along the guide pipe 2. When the raw material moves to the position of the cone block 4, the raw material falls outward along the outer arc wall of the cone block 4 and falls back to the top of the raw material to accumulate. This process is repeated to gradually complete the mixing and stirring of the raw material. There are no dead corners, and the mixing and stirring effect of the raw material in the sealed diaphragm is good.

[0037] It should be noted that the operation of the device can be controlled by an external control unit, so that the staff can control the running time of the device when mixing different amounts of raw materials.

[0038] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the storage cylinder 1 includes two parts: a cylinder body 11 and a cylinder cover 12, and the cylinder cover 12 is threaded into the top opening of the storage cylinder 1.

[0039] In this embodiment, please refer to Figure 1 and Figure 2 As shown, when the device is in use, the operator unscrews the cylinder cap 12 from the top opening of the cylinder body 11. At this time, various raw materials can be poured into the storage cylinder 1 in the corresponding proportion through the top opening of the cylinder body 11 (the raw materials can be rubber materials, fluoroplastic materials, thermoplastic elastomers, etc.). The feeding operation of the device is simple.

[0040] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the feed tube 2 includes a threaded tube 21, which is fixedly installed in the bottom opening of the storage cylinder 1. A guide tube 22 is fixedly installed above the threaded tube 21 by several connecting rods.

[0041] In this embodiment, please refer to Figure 2 and Figure 3 As shown, when the raw material is poured into the storage cylinder, some of the raw material at the bottom of the storage cylinder 1 slides along the inner wall of the storage cylinder and slides into the guide pipe 2 through the gap between the guide pipe 22, the threaded pipe 21 and several connecting rods. When the air is injected into the guide pipe 2, due to the large amount of raw material in the storage cylinder blocking the gap between the guide pipe 22, the threaded pipe 21 and several connecting rods and the inertia of the airflow itself, almost all of the airflow flows directly upward into the guide pipe 22, and carries a small amount of raw material at the threaded pipe 21 upward with it. The device has a simple structure and low production cost.

[0042] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the top end of the conduit 22 is flared and fits with the bottom side of the cap 12 with a gap. The inner and outer circumferences of the bottom opening of the conduit 22 are both arc-shaped.

[0043] The bottom opening of the threaded pipe 21 is threaded with a cap 23, and the top side of the cap 23 is provided with several vent holes 24 at equal intervals.

[0044] In this embodiment, please refer to Figure 2 and Figure 3 As shown, the flared opening at the top of the conduit 22 is designed to increase the cross-sectional area of ​​the opening at the top of the conduit 22, so that the material sliding out of the opening at the top of the conduit 22 can diffuse directly outward.

[0045] The gas injected into the feed pipe 2 will first be injected into the cap 23, and then the airflow will be divided into several small streams that flow upward through the exhaust hole 24 and into the threaded pipe 21 and the guide pipe 22.

[0046] The raw material that slides into the feed tube 2 is placed on the cover 23 and will not slide out of the feed tube 2. The gas injected into the feed tube 2 is first injected into the cover 23. Since the amount of gas passing through the several exhaust holes 24 is limited, a high-pressure chamber can be formed in the cover 23 to increase the pressure difference at both ends of the exhaust holes 24, thereby increasing the flow rate of the gas discharged from the exhaust holes 24.

[0047] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the air injection mechanism 3 includes a heat insulation shell 31, the top of which is inserted into the cover 23 and rotatably connected to the cover 23 through a bearing. The interior of the shell has a cavity 32 and a cavity 33 formed from top to bottom. An air pump 34 is fixedly installed in the cavity 32, and the air pump 34’s inlet and outlet ends are respectively inserted into the cavity 33 and the cover 23.

[0048] In this embodiment, please refer to Figure 2 and Figure 4 As shown, during the use of the device, the air pump 34 is started to continuously draw gas from the second cavity 33 and inject the gas into the cover 23. (The air pump 34 can be a high-temperature vortex pump or a high-temperature resistant centrifugal fan, etc.) Since the air pump 34 is located in the first cavity 32 and is isolated by the heat insulation shell 31, the temperature of the environment in which the air pump 34 is running can be reduced.

[0049] After the raw materials are mixed and stirred, the workers unscrew the cap 23 from the threaded tube 21 to release the blockage. At this time, the raw materials in the storage cylinder 1 slide into the threaded tube 21 along the inclined inner wall at the bottom of the storage cylinder 1 and slide out of the storage cylinder 1 from the threaded tube 21. Then, the storage device can be placed directly below the threaded tube 21 so that the raw materials fall directly into the storage device.

[0050] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 5 As shown, the exhaust mechanism 5 includes a mesh ring 51, which is fixedly installed on the outer peripheral wall of the top of the storage cylinder 1. The inner ring wall of the mesh ring 51 is coplanar with the inner ring wall of the storage cylinder 1. A ring tube 52 is fixedly sleeved on the outer peripheral wall of the storage cylinder 1 at the position corresponding to the mesh ring 51. The outer ring wall of the mesh ring 51 is inserted into the opening of the ring tube 52. Several connecting pipes 53 are fixedly installed through the bottom side of the ring tube 52 at equal intervals.

[0051] In this embodiment, please refer to Figure 2 and Figure 5 As shown, the airflow discharged from the top opening of the feed pipe 2 blows onto the conical block 4, thereby dividing the airflow into several parts relatively evenly along the conical inclined surface of the conical block 4. Then, the divided airflow flows towards the mesh ring 51, flows into the ring pipe 52 after passing through the holes of the mesh ring 51, and is discharged from the ring pipe 52 by the connecting pipe 53. Due to the driving effect of the airflow between the conical block 4 and the mesh ring 51 on the raw material, the raw material can be diffused to a wider range in all directions.

[0052] By using several connecting pipes 53 to guide the airflow from various locations within the ring pipe 52, a large pressure difference can be avoided at certain locations of the ring pipe 52, which would affect the diffusion flow of the airflow discharged from the top opening of the feed pipe 2 to the surrounding areas.

[0053] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the filter mechanism 6 includes a housing 61, which is located at the bottom end of the connecting pipe 53 and is fixedly sleeved on the outer periphery of the storage cylinder 1. The top end of the housing 61 is provided with a cover 62, and the bottom end of the cover 62 is inserted into the top opening of the housing 61. The bottom end of the connecting pipe 53 is fixedly inserted through the cover 62. A filter element 63 is slidably installed inside the housing 61. The bottom end of the filter element 63 is provided with a mesh plate 64, and the mesh plate 64 is fixedly connected to the inner wall of the housing 61. Several heating tubes 65 are fixedly installed on the bottom side of the housing 61, and the bottom opening of the heating tubes 65 is connected to the inside of the cavity 33 through a pipe connector.

[0054] In this embodiment, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the gas discharged from the connecting pipe 53 flows directly through the cover 62 into the top of the outer shell 61. Then the gas passes through the holes of the filter element 63 and the mesh plate 64 (the filter element 63 can be a HEPA + activated carbon composite filter purifier), flows to the bottom of the outer shell 61, and finally passes through the heating pipe 65 and is guided into the cavity 33 by the pipe connector (the pipe connector can be composed of several rubber tubes and several interfaces) for the air pump 34 to draw in. During this process, the filter element 63 removes odors and dust and other harmful substances from the gas, and the heating pipe 65 completes the heating of the gas.

[0055] When replacing filter element 63, the operator lifts the cover 62 upwards. As the flexible tube (connecting tube 53 is a flexible tube) deforms and bends, the cover 62 can be directly removed from the outer shell 61. Then, the filter element 63 can be directly removed from the outer shell 61 through the top opening of the outer shell 61 (the distance between the ring tube 52 and the outer shell 61 is greater than the height of the filter element 63). Then, a new filter element 63 is inserted into the outer shell 61, and the cover 62 is reinserted into the top opening of the outer shell 61 to complete the replacement of filter element 63.

[0056] It should be noted that when the air pump 34 is running, it can continuously draw gas from the housing 61 through the pipe connector, so that a negative pressure chamber is formed inside the housing 61, thereby firmly adsorbing and fixing the cover 62 to the top of the housing 61. The gas inside the housing 61 will not overflow from the top opening of the housing 61, thus affecting the use of the device.

[0057] Working principle: When using this improved sealing diaphragm raw material mixing device, the operator pours various raw materials into the storage cylinder, and then starts the air pump 34 and heating pipe 65 to form a gas circulation in the device, thereby completing the mixing and stirring of the raw materials by the airflow.

[0058] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0059] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
