Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary facilities for carbon molecular sieve production, and in particular to a feeding device for a kneader. Background Technology

[0002] Currently, carbon molecular sieves are mostly produced using phenolic resin as raw material, through processes such as grinding, drying, ball milling, mixing and kneading, extrusion, sieving, sintering and carbonization, and pore adjustment. In the mixing and kneading process, fine phenolic resin powder is mixed with environmentally friendly binders such as CMC or PVA, adjusting the moisture content to a dough-like state of 10-15%, and then extruded into a sheet. When feeding the fine phenolic resin powder into the kneader, the kneader's cover is opened, and the powder is manually poured in. This process inevitably generates dust. Although a dust extraction hood is installed above it, the particle size of the fine phenolic resin powder is very small, ranging from 1 to 10 μm, making it extremely easy to fly and disperse. Therefore, it still causes localized dust pollution, affecting the workshop's working environment and the health of the workers.

[0003] Therefore, it is necessary to develop a feeding device for a kneader to address the aforementioned shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for a kneader, which uses an elevated silo for enclosed feeding, reducing dust during the feeding process and improving the working environment.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model relates to a feeding device for a kneader, which is located directly above the main body of the kneader. It includes a heightening bracket, a hopper, and an electric valve. The heightening bracket spans the main body of the kneader, and the hopper is mounted on the middle beam of the heightening bracket and located above the main body of the kneader. The electric valve is located at the discharge port at the bottom of the hopper. A feed pipe connector communicating with the kneading cavity is provided on the top surface of the flip-top cover of the main body of the kneader. A flexible material distribution tube connects the feed pipe connector and the discharge port at the bottom of the hopper.

[0007] Furthermore, it also includes a weighing sensor. Four support plates are evenly distributed around the bottom circumference of the silo tank. The weighing sensor is installed between the support plates and the central beam of the heightening bracket. The weighing sensor feeds back signals to the equipment's electrical control system.

[0008] Furthermore, a top cover is connected to the top opening of the silo tank via flange bolts, and an inlet communicating with the inner cavity of the silo is provided on the top surface of the top cover. The discharge port of the screw conveyor is connected to the inlet via a flexible cloth cylinder.

[0009] Furthermore, it also includes a vent pipe, and the top surface of the flip-up cover is also provided with a vent pipe connector that connects to the kneading cavity. The top surface of the cover is also provided with a venting interface that connects to the hopper cavity. The vent pipe connects between the vent pipe connector and the venting interface.

[0010] Furthermore, it also includes a snap-fit ​​ring sleeve, the root of which is fixedly connected to the top surface of the top cover, and the cantilever end of which is a ring structure and is sleeved outside the vent pipe for auxiliary support.

[0011] Furthermore, the vent pipe is specifically made of plastic corrugated pipe.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This utility model of a kneader feeding device adds a silo tank above the kneader body to temporarily store the fine phenolic resin powder to be added. Opening an electric valve allows the material to flow downwards under its own weight into the kneading cavity of the kneader body, eliminating the need for manual feeding. Feeding occurs with the flip-top cover closed, reducing dust spillage. A flexible material distribution cylinder connects the feed pipe joint and the silo tank, ensuring both unimpeded feeding and easy opening of the flip-top cover. This utility model of a kneader feeding device uses an elevated silo tank for enclosed feeding, reducing dust during the feeding process and improving the working environment.

[0014] Furthermore, by adding a weighing sensor between the heightening bracket and the silo tank, the amount of material fed into the silo tank can be fed in real time. When the set feeding weight is reached, the electrical control system controls the electric valve to close and prevent further feeding. This replaces manual weighing and reduces labor intensity. By adding a feed inlet on the top surface of the top cover and connecting it to the discharge outlet at the top of the screw conveyor via a distribution cylinder, automatic feeding of the silo tank can be achieved, reducing the labor intensity of manual feeding. By adding the aforementioned material level sensor, the material top surface position in the silo tank can be monitored, preventing material shortages and overflows. By setting a vent pipe between the vent pipe joint and the vent interface, the kneading cavity of the kneader body and the storage cavity of the silo tank are connected. When the electric valve is opened to feed material, there is no air resistance, making feeding smoother. At the same time, the dust raised when the material is fed into the kneading cavity can be returned to the storage cavity through the vent pipe, reducing dust overflow and avoiding waste.

[0019] The core of this utility model is to provide a feeding device for a kneader, which uses an elevated silo tank for enclosed feeding, reducing dust during the feeding process and improving the working environment.

[0020] The technical solutions of the present utility model 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 the present utility model, and not all of them. 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.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In one specific implementation, such as Figure 1 and Figure 2 As shown, the feeding device of this utility model kneader is located directly above the kneader body 1, and includes a heightening bracket 2, a hopper 3, and an electric valve 5. The heightening bracket 2 spans across the kneader body 1 and is a welded steel bracket. The hopper 3 is mounted on the middle beam of the heightening bracket 2 and is located above the kneader body 1, with the hopper 3 arranged vertically. The electric valve 5 is located on the discharge port at the bottom of the hopper 3, and can be a gate valve or a butterfly valve. The top surface of the flip-up cover 101 of the kneader body 1 is provided with a feed pipe connector 103 that communicates with the kneading cavity, and the two are welded together. A flexible material distribution tube connects the feed pipe connector 103 and the discharge port at the bottom of the hopper 3.

[0023] By adding a hopper 3 above the kneader body 1, the fine phenolic resin powder to be added is temporarily stored. The material flows downwards into the kneading cavity of the kneader body 1 by its own weight after opening the electric valve 5, avoiding manual feeding. Feeding is carried out with the flip-top cover 101 closed, reducing dust spillage. A flexible material distribution tube connects the feed pipe joint 103 and the hopper 3, ensuring that feeding is not hindered while allowing the flip-top cover 101 to be opened. This kneader feeding device uses an elevated hopper for enclosed feeding, reducing dust during the feeding process and improving the working environment.

[0024] In one specific embodiment of this utility model, such as Figure 1 As shown, the feeding device of this kneader also includes a weighing sensor 6. Four support plates are evenly distributed around the bottom circumference of the hopper 3, and the base of each support plate is directly welded to the outer wall of the hopper 3. The weighing sensor 6 is installed between the support plates and the central beam of the lifting bracket 2; that is, the hopper 3 is mounted on the lifting bracket 2 via the weighing sensor 6. There are also four weighing sensors 6, which feed back signals to the equipment's electrical control system.

[0025] By adding a weighing sensor 6 between the riser bracket 2 and the silo tank 3, the amount of material fed into the silo tank 3 can be fed in real time. When the set feeding weight is reached, the electrical control system controls the electric valve 5 to close to prevent further feeding. This replaces manual weighing and reduces the intensity of manual labor.

[0026] In one specific embodiment of this utility model, such as Figure 1 As shown, a top cover 301 is connected to the top opening of the silo tank 3 by flange bolts. The top surface of the top cover 301 is provided with a feed inlet 302 that communicates with the inner cavity of the silo. The two are welded together. The screw conveyor 8 is set at an inclination, with the bottom end being the feeding end. The discharge port at the top of the screw conveyor 8 is connected to the feed inlet 302 through a flexible material distribution cylinder.

[0027] Specifically, it also includes a level sensor, which is installed in the middle of the top cover 301. The level sensor monitors the top surface position of the material in the silo tank 3. The level sensor is a non-contact infrared sensor and feeds back a signal to the equipment's electrical control system.

[0028] By adding a feed inlet 302 to the top surface of the top cover 301 and connecting it to the discharge port at the top of the screw conveyor 8 via a material distribution cylinder, automatic feeding of the silo tank 3 can be achieved, reducing the labor intensity of manual feeding; by adding the material level sensor, the position of the material top surface of the silo tank 3 can be monitored, avoiding material shortage and overflow.

[0029] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the feeding device of the kneader of this utility model also includes an air pipe 7. The top surface of the flip-up cover 101 is also provided with an air pipe connector 104 that connects to the kneading cavity. The top surface of the top cover 301 is also provided with an air interface 303 that connects to the material hopper cavity. The air pipe 7 connects between the air pipe connector 104 and the air interface 303.

[0030] Specifically, such as Figure 1 As shown, the feeding device of the kneader of this utility model also includes a snap ring sleeve 4. The root of the snap ring sleeve 4 is fixedly connected to the top surface of the top cover 301 by screws. The cantilever end of the snap ring sleeve 4 is a ring structure and is sleeved on the outside of the air pipe 7 for auxiliary support.

[0031] Specifically, such as Figure 1 As shown, the vent pipe 7 is specifically made of plastic corrugated pipe.

[0032] Obviously, the vent pipe 7 can also be a rubber hose or a regular plastic hose. However, the plastic corrugated pipe has better flowability and will not be bent or blocked due to the action of the flip-top cap 101.

[0033] By setting a vent pipe 7 between the vent pipe connector 104 and the vent interface 303, the kneading cavity of the kneader body 1 and the storage cavity of the hopper 3 are connected. When the electric valve 5 is opened to discharge material, there is no air resistance, and the material discharge is smoother. At the same time, the dust raised when the material is discharged into the kneading cavity can also return to the storage cavity through the vent pipe 7, reducing the overflow of dust and avoiding waste.

[0034] The working principle of the feeding device of this utility model kneader is as follows: During the feeding process into the kneader body 1, the hydraulic cylinder 102 is initially in the ejected state, and the flip-top cover 101 is closed and fastened to the top opening of the kneading chamber of the kneader body 1. The operator operates the control panel of the equipment's electrical control system, opening the electric valve 5. The phenolic resin powder temporarily stored in the silo tank 3, under its own weight, enters the kneading chamber of the kneader body 1 through the discharge port at the bottom and the material distribution cylinder, and then through the feed pipe connector 103. The raised dust can return upwards along the vent pipe 7 to the storage chamber of the silo tank 3, preventing dust overflow. When the signal from the weighing sensor 6 reaches the set feeding mass, the electrical control system controls the electric valve 5 to close, preventing further feeding. When the kneader body 1 discharges material, the hydraulic cylinder 102 retracts, pulling the swing arm 105, causing the flip-top cover 101 to flip open, and then the kneading chamber of the kneader body 1 flips outwards to discharge the material.

[0035] In summary, the feeding device for this kneader, by adding a hopper 3 above the kneader body 1, temporarily stores the fine phenolic resin powder to be added. Opening the electric valve 5 allows the material to flow downwards under its own weight into the kneading cavity of the kneader body 1, avoiding manual feeding. Feeding occurs with the flip-top cover 101 closed, reducing dust spillage. A flexible material distribution tube connects the feed pipe joint 103 and the hopper 3, ensuring both feeding and the ability to open the flip-top cover 101. This feeding device uses an elevated hopper for enclosed feeding, reducing dust during the feeding process and improving the working environment. Furthermore, by adding a weighing sensor 6 between the elevated support 2 and the hopper 3, the amount of material fed into the hopper 3 can be fed in real time. When the set feeding weight is reached, the electrical control system closes the electric valve 5 to prevent further feeding. This replaces manual weighing, reducing labor intensity. By adding a feed inlet 302 to the top surface of the top cover 301 and connecting it to the discharge outlet at the top of the screw conveyor 8 via a material distribution cylinder, automatic feeding of the hopper 3 can be achieved, reducing the labor intensity of manual feeding. By adding the material level sensor, the position of the material top surface of the hopper 3 can be monitored, avoiding material shortages and overflows. By setting a vent pipe 7 between the vent pipe connector 104 and the vent interface 303, the kneading cavity of the kneader body 1 and the storage cavity of the hopper 3 are connected. When the electric valve 5 is opened to discharge material, there is no air resistance, and the material discharge is smoother. At the same time, the dust raised when the material is discharged into the kneading cavity can also return to the storage cavity through the vent pipe 7, reducing the overflow of dust and avoiding waste.
