Description

Technical Field

[0001] The utility model relates to the technical field of dust treatment in internal mixer technology, and specifically relates to an air conveying device for internal mixer dust. Background Art

[0002] In the prior art, an internal mixer, also known as a kneader, can be mainly used for the production of rubber in chemical enterprises, such as the production of cable materials. Its specific working principle is to introduce matrix resin, inorganic flame retardant, filler, and various additives into the internal mixer, and at a certain temperature, through the shearing force of the rotor in the machine, the raw materials are mixed to make mixed rubber.

[0003] However, during the specific working process of the internal mixer, a lot of dust will be generated during the production of rubber and plastic inside. On the one hand, the dust will seriously affect the working efficiency and quality of the internal mixer. On the other hand, it will have a greater impact on the staff and also have a great impact on the workshop environment. Therefore, it is necessary to treat this dust.

[0004] First of all, the dust collection work is relatively convenient. A dust collection bin can be directly installed at the rear end of the internal mixer to collect the dust generated by the internal mixer. However, during the specific treatment, usually the dust treatment workshop is set in another production plant at a certain distance from the internal mixer. Therefore, a conveying mechanism is also needed to convey this dust to the treatment equipment, but in the prior art, the efficient conveyance of this dust is often not achieved.

[0005] Therefore, in order to solve the above problems, it is necessary to develop an air conveying device for internal mixer dust with a reasonable structure that can efficiently achieve dust conveyance. Content of the Utility Model

[0006] The purpose of the utility model is to provide an air conveying device for internal mixer dust aiming at the deficiencies existing in the prior art. Its technical solution is as follows:

[0007] An air conveying device for internal mixer dust includes a dust collection bin. A pneumatic conveying bin is arranged below the dust collection bin through a feeding pipeline. A horizontal partition is arranged in the pneumatic conveying bin. The area above the partition is set as a storage area, and the area below the partition is set as a pulse area. Feeding openings are also arranged on both sides of the partition. The dust in the dust collection bin falls into the storage area through the feeding pipeline, and then falls into the pulse area through the feeding openings in the storage area.

[0008] Push devices are installed on both outer sides of the pneumatic conveying bin. The two push devices are both horizontally arranged and are both located above the partition. The main shaft of the push device horizontally extends into the storage area, and correspondingly passes through the feeding opening downward in an L-shaped structure, and a feeding blocking plate is installed at the shaft end.

[0009] The described blanking plug plate is closely arranged on the lower end face of the partition board, and the size of the blanking plug plate is correspondingly set. The blanking plug plate can correspondingly block the whole blanking port, and can be moved under the drive of the pushing device to open the blanking port.

[0010] On the right lower end of the pulse area of the pneumatic conveying bin, a pulse pressure device is also arranged through an air inlet pipe, and an air outlet pipe is correspondingly installed on the left lower end. The air outlet pipe is correspondingly connected and installed with a pulse conveying pipe. Through the pulse pressure device, the dust in the pulse area can be sent into the pulse conveying pipe in a stamping manner.

[0011] Furthermore, inclined installation areas are arranged on both sides of the dust collecting bin, and vibration motors are correspondingly installed on the installation areas on both sides.

[0012] Furthermore, a blanking valve is installed on the blanking pipe.

[0013] Furthermore, inclined installation areas are respectively arranged on both upper ends of the pneumatic conveying bin, and stirring motors are installed on the installation areas on both sides. The shaft body of the stirring motor extends into the storage area, and a stirring rod is installed at the shaft end.

[0014] Furthermore, two pushing devices are correspondingly installed on both sides of the pneumatic conveying bin. The main shafts of the two pushing devices on each side correspondingly extend into the pneumatic conveying bin, and the main shafts of the two pushing mechanisms are located at the front and rear positions of the blanking port.

[0015] Furthermore, a first solenoid valve is installed on the air inlet pipe, a second solenoid valve is installed on the air outlet pipe, and a bypass pipe is also arranged on the pulse pressure device. A third solenoid valve is installed on the bypass pipe, and a number of branch pipes are arranged on the bypass pipe. The branch pipes are correspondingly connected to the pulse conveying pipe.

[0016] Beneficial effects: The utility model has the following beneficial effects:

[0017] 1) In this device, the material of the dust is conveyed by the pulse air pressure conveying method, which has the characteristics of long conveying distance, simple control and high conveying efficiency. When specifically conveying the dust in this device, the blanking port is blocked by the blanking plug plate to form a sealed space, realizing the efficient conveying of the dust. The structural setting is ingenious and reasonable.

[0018] 2) In this device, after the dust is discharged in the dust collecting bin and falls into the pneumatic conveying bin, the pneumatic conveying bin is provided with an upper storage area and a lower pulse area through the partition board. One of the two areas is used for storing materials, and the other area is used for pulse feeding. The structural setting is reasonable.

[0019] 3) In this device, the blocking and opening of the material discharge port can be realized specifically through the setting of the pushing device and the material discharge blocking plate. When it is opened, the discharge of dust can be realized. When it is blocked, the lower pulse area becomes a closed area, which can not only not affect the dust discharge but also increase the dust pulse feeding effect. Description of the Drawings

[0023] The present utility model will be further illustrated below in conjunction with the drawings and specific embodiments. These embodiments are implemented on the premise of the technical solution of the present utility model. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model.

[0024] As Figure 1 , Figure 2 and Figure 3 shown, a pneumatic conveying device for dust in a mixer includes a dust collection bin 1. A pneumatic conveying bin 3 is arranged below the dust collection bin 1 through a material discharge pipe 2. A horizontal partition 4 is arranged in the pneumatic conveying bin 3. The area above the partition 4 is set as a storage area 5, and the area below the partition 4 is set as a pulse area 6. Material discharge ports 7 are arranged on both sides of the partition 4. Dust in the dust collection bin 1 falls from the material discharge pipe 2 into the storage area 5, and then falls from the material discharge port 7 in the storage area 5 into the pulse area 6;

[0025] Pushing devices 8 are installed on both outer sides of the pneumatic conveying bin 3. The two pushing devices 8 are both horizontally arranged and are both located above the partition 4. The main shaft 9 of the pushing device 8 horizontally extends into the storage area 5, and correspondingly passes through the material discharge port 7 downward in an L-shaped structure, and a material discharge blocking plate 10 is installed at the shaft end;

[0026] The material discharge blocking plate 10 is closely arranged on the lower end face of the partition 4, and the size of the material discharge blocking plate 10 is correspondingly set. The material discharge blocking plate 10 can correspondingly block the entire material discharge port 7, and can be moved under the drive of the pushing device 8 to open the material discharge port 7;

[0027] On the right lower end of the pulse area 6 of the pneumatic conveying bin 3, there is also a pulse pressure device 12 installed through an air inlet pipe 11. On the left lower end, an air outlet pipe 13 is correspondingly installed. The air outlet pipe 13 is correspondingly connected to a pulse conveying pipe 14. Through the pulse pressure device 12, the dust in the pulse area 6 can be sent into the pulse conveying pipe 14 in a stamping manner.

[0028] On both sides of the dust collection bin 1, there are also inclined installation areas 15, and vibration motors 16 are correspondingly installed on the installation areas 15 on both sides.

[0029] A blanking valve 17 is installed on the blanking pipe 2.

[0030] On both upper ends of the pneumatic conveying bin 3, there are also inclined installation areas 15 respectively. On the installation areas 15 on both sides, stirring motors 18 are installed. The shaft body of the stirring motor 18 extends into the storage area 5, and a stirring rod 19 is installed at the shaft end.

[0031] Two corresponding pushing devices 8 are installed on both sides of the pneumatic conveying bin 3. The main shafts 9 of the two pushing devices 8 on each side correspondingly extend into the pneumatic conveying bin 3, and the main shafts 9 of the two pushing mechanisms are located at the front and rear sides of the blanking port 7.

[0032] A first solenoid valve 101 is installed on the air inlet pipe 11, a second solenoid valve 102 is installed on the air outlet pipe 13, and the pulse pressure device 12 is also provided with a bypass pipe 20. A third solenoid valve 103 is installed on the bypass pipe 20, and the bypass pipe 20 is provided with several branch pipes 21. The branch pipes 21 are correspondingly connected to the pulse conveying pipe 14.

[0033] The specific working process of this device is as follows: First, the dust in the dust collection bin makes the dust fall from the blanking pipe into the pneumatic conveying bin through the vibration of the vibration motors on both sides. There is a blanking valve installed on the blanking pipe, which can control the blanking process, the blanking amount, etc. at any time.

[0034] The falling dust first falls into the storage area of the pneumatic conveying bin, that is, on the partition plate. There are blanking ports on the partition plate itself, but the blanking ports are blocked by the blanking plug on the lower end face as a whole. However, driven by the pushing devices on both sides, the blanking plug can be driven to move left and right, and the main shaft of the pushing device can just pass through the position of the blanking port and then install the blanking plug correspondingly. The structural design is relatively ingenious.

[0035] When the blanking plug is moved away by the pushing devices on both sides, the position of the blanking port is opened, and the dust in the storage area can fall downward from the blanking port into the pulse area. During the blanking process, the blanking can be assisted by the action of the stirring motor and the stirring rod, and the dust will not accumulate.

[0036] After a certain amount of dust has fallen from the material discharge opening, the material discharge blocking plate is driven by the pushing device to completely block the material discharge opening. At this time, a sealed space is formed in the lower pulse area. Then, the pulse pressure device, the first solenoid valve on the intake pipe, and the second solenoid valve on the outlet pipe are opened. The dust in the pulse area is sent into the pulse conveying pipe through the pulse pressure equipment to achieve conveying.

[0037] After that, control is used to open the material discharge opening. After the dust is discharged, the next dust conveying is realized, and then the overall dust conveying work is completed. Since the upper material discharge opening is correspondingly closed during the pulse material conveying of this device, a sealed space is formed in the pulse area. Therefore, the material conveying is very efficient and does not affect the material discharging process.

[0038] Moreover, a bypass pipe and a branch pipe are provided in this device. During the process of dust discharging from the material discharge opening, the first solenoid valve and the second solenoid valve can be closed, and then the third solenoid valve on the bypass pipe is opened. Then, pulse air pressure is introduced into the bypass pipe. The branch pipe is connected to the pulse conveying pipe. Therefore, during this process, air pressure can be directly conveyed into the pulse conveying pipe to achieve the conveying of dust. The overall structural setting is very reasonable and ingenious.

[0039] The above specific implementation manner is only a preferred embodiment of the present invention, and is not used to limit the implementation and the scope of the claims of the present invention. Any equivalent changes and modifications made based on the content of the patent protection scope of the present invention shall be included within the scope of the patent application of the present invention.
