Description

Technical Field

[0001] The utility model relates to the technical field of carbon black granulation, in particular to a carbon black granule raw material filler pipeline blockage alarm device. Background Technique

[0002] Carbon black granulation is a process of making powdery carbon black with poor fluidity and easy to fly into granules in a granulator by relying on its continuous rotation. After granulation, carbon black is convenient for transportation and use, and at the same time, it also reduces the pollution to the working environment. Carbon black granulation is divided into two types: wet granulation and dry granulation. In order to continuously supply carbon black powder to the granulator, a carbon black powder storage tank is needed. Among them, the conveying pipeline between the carbon black powder storage tank and the granulator can be regarded as a filler pipeline.

[0003] In the prior art, the publication number CN207943401U discloses a carbon black powder storage tank, which includes a tank body, a top cover is arranged on the upper part of the tank body, a discharge hopper is arranged on the lower part of the tank body, the discharge hopper is connected with a conveying pipe, an air pump is arranged on one side of the upper part of the tank body, four air suction outlets are arranged in the tank body of the air pump, two air suction baffles with slopes are arranged above the two upper air suction outlets, a tank body partition plate is arranged above the two lower air suction outlets, a flow gap is arranged on the tank body partition plate, a blanking roller is arranged in the discharge hopper, a section of detachable metal hose is arranged on the conveying pipe, a flange cover for removing pipeline rust stains is arranged on one side of the conveying pipe, the conveying pipe is arranged to pass through a group of fire dikes, and an arc baffle is arranged at the air suction outlet. The carbon black powder storage tank has a simple structure, scientific and reasonable design. The air suction device at the inlet ensures that the powdery material enters the tank body more smoothly, will not dirty the inlet and cause air pollution due to powder flying, and the anti-blocking roller arranged at the outlet can ensure smooth blanking and safer production.

[0004] However, since the carbon black powder conveying pipe of this solution is not provided with a blockage alarm device, in the actual carbon black granulation production process, it is very easy to cause the phenomenon of delayed feeding due to the blockage of carbon black powder in the conveying pipe, and traditional granulators are often only detected when the carbon black powder is exhausted or lower than the minimum feeding value, which will have an adverse impact on the production of carbon black granulation.

[0005] Therefore, a carbon black granule raw material filler pipeline blockage alarm device is proposed, which has the advantage of detecting carbon black powder blockage, and thus solves the problems in the above background technique. Content of the Utility Model

[0006] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a carbon black granule raw material filler pipeline blockage alarm device is proposed.

[0008] As a further description of the above technical solution: a motor is fixed to the top of the carbon black storage tank through a mounting base, and a stirring paddle is fixed to the output end of the motor through a coupling, the part of the stirring paddle extending into the interior of the carbon black storage tank is provided with a number of columnar stirring rods, and the bottom of the stirring paddle is obliquely welded with two scrapers through a connecting rod, and the two scrapers are in contact with the inner wall of the lower conical part of the carbon black storage tank.

[0014] In the present utility model, a detection cylinder with an infrared emitting tube and an infrared receiving tube is connected to the conveying pipe of the carbon black storage tank through a flange. During detection, the infrared emitting tube embedded on the left glass sheet emits infrared rays. Since the carbon black powder is in a loose and continuous state during the feeding stage, a part of the infrared rays passing through the carbon black powder is received by the infrared receiving tube embedded in the right glass sheet cavity. The PLC controller then determines that this state is smooth feeding. When the carbon black powder is blocked in the conveying pipe and cannot be fed, the infrared rays emitted by the infrared emitting tube are blocked by the accumulated carbon black powder and cannot be received by the infrared receiving tube. Then the PLC controller determines that this state is a feeding blockage and activates the buzzer alarm to remind the staff to dredge the conveying pipe in time. Compared with the existing carbon black storage tank, it can realize the alarm for the blockage state of the conveying pipe so as to dredge it in time, which is beneficial to the efficient progress of carbon black granulation.

AsFigures 1-3 As shown in Figures 1-3 , a carbon black granule raw material filler pipeline blockage alarm device according to an embodiment of the present utility model includes a carbon black storage tank 1. A delivery pipe 5 is connected to the bottom of the carbon black storage tank 1, and a detection cylinder 6 is connected to the surface of the delivery pipe 5 through a flange. A left glass sheet 12 is embedded in the left side wall of the detection cylinder 6, and an infrared transmitting tube 13 is embedded in the convex surface of the left glass sheet 12. A maintenance nozzle 8 is welded to the periphery of the left glass sheet 12, and a sealing rubber plug 16 is inserted into the opening at the end face of the maintenance nozzle 8.

A right glass sheet 7 is embedded in the right side wall of the detection cylinder 6, and an infrared receiving tube 14 is embedded in the concave surface of the right glass sheet 7 corresponding to the infrared transmitting tube 13. A PLC controller 17 and a buzzer 18 are sequentially installed on the outer wall of the carbon black storage tank 1 from bottom to top. Both the infrared transmitting tube 13 and the infrared receiving tube 14 are electrically connected to the PLC controller 17, and the output end of the PLC controller 17 is electrically connected to the buzzer 18. A feed inlet 3 is provided on the upper left side of the carbon black storage tank 1, and an exhaust pipe with an exhaust valve 4 is provided at the edge of the top surface of the carbon black storage tank 1. In order to facilitate the maintenance of the infrared transmitting tube 13 and the infrared receiving tube 14, a maintenance nozzle 8 and a sealing rubber plug 16 are provided on the detection cylinder 6, so that the staff can reach the installation position of the left glass sheet 12 (a relief opening corresponding to the left glass sheet 12 is provided on the left side wall of the detection cylinder 6), and the left glass sheet 12 can be removed by removing the screws on the mounting ears 15. The internal space of the maintenance nozzle 8 should be larger than the size of the left glass sheet 12 to facilitate the removal of the left glass sheet 12, so as to replace and maintain the infrared transmitting tube 13 and the infrared receiving tube 14. The control mode of the present utility model is automatically controlled by the PLC controller 17. The control circuit of the PLC controller 17 can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art, and the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail;

[0023] In one embodiment, a motor 2 is fixed to the top of the carbon black storage tank 1 through a mounting base, and a stirring paddle 10 is fixed to the output end of the motor 2 through a coupling. The part of the stirring paddle 10 extending into the interior of the carbon black storage tank 1 is provided with a plurality of columnar stirring rods, and the bottom of the stirring paddle 10 is welded with two scrapers 11 at an angle through a connecting rod. The two scrapers 11 are in contact with the inner wall of the lower conical part of the carbon black storage tank 1. By starting the motor 2, the stirring paddle 10 fixed at its output end is driven to rotate. Combined with the arrangement of the plurality of columnar stirring rods and the two scrapers 11, the carbon black powder in the carbon black storage tank 1 is stirred to maintain the feeding effect of the carbon black powder. For the motor 2, the control method of the utility model is to control it by manually starting and shutting down the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in this field, and the utility model is mainly used to protect mechanical devices, so the utility model no longer explains the control method and wiring arrangement in detail.

[0024] In one embodiment, a clearance opening is opened on the left side wall of the detection tube 6 corresponding to the left glass piece 12, and the inner wall of the clearance opening is tightly connected to the side surface of the left glass piece 12, that is, the clearance opening and the left glass piece 12 are tightly fitted together, which facilitates the disassembly of the left glass piece 12. Combined with the setting of the maintenance nozzle 8, the infrared emitting tube 13 and the infrared receiving tube 14 can be replaced or maintained.

[0025] In one embodiment, the cross-sections of the left glass sheet 12 and the right glass sheet 7 are both arc-shaped, and both sides of the left glass sheet 12 and the right glass sheet 7 are coated with an anti-fingerprint coating agent. The arc-shaped left glass sheet 12 and the right glass sheet 7 correspond to the inner wall contour of the detection tube 6. The provision of the anti-fingerprint coating agent can maintain the smoothness of the left glass sheet 12 and the right glass sheet 7, and is not easy to cause carbon black powder to adhere, thereby avoiding interference with blockage detection.

[0026] In one embodiment, the end face of the feed port 3 is hinged with a cover plate 9, and a rubber pad is bonded to the side of the cover plate 9 facing the feed port 3. The arrangement of the cover plate 9 and the rubber pad is conducive to feeding and prevents the carbon black powder from leaking out.

[0027] In one embodiment, the inner diameter of the detection cylinder 6 is the same as the inner diameter of the conveying pipe 5, and a circular flange is provided at each end of the detection cylinder 6. The circular flange is provided to facilitate the connection between the detection cylinder 6 and the conveying pipe 5. The conveying pipe 5 and the detection cylinder 6 have the same inner diameter so as to maintain the smoothness of the carbon black powder in the conveying state, so that the installation of the detection cylinder 6 will not interfere with the conveying of the carbon black powder.

[0028] Working principle:

[0029] During use, first ensure that there is sufficient carbon black powder inside the carbon black storage tank 1. Then start the motor 2 to drive the stirring paddle 10 fixed to its output end to rotate, agitate the carbon black powder in the carbon black storage tank 1, maintain the feeding effect of the carbon black powder, and introduce it into the feeding end of the carbon black granulator through the conveying pipe 5. When detecting the blockage of the conveying pipe 5, the infrared emitting tube 13 embedded and installed on the left glass sheet 12 emits infrared rays. Since the carbon black powder is in a loose and continuous state during the feeding stage, part of the infrared rays passing through the carbon black powder is received by the infrared receiving tube 14 embedded and installed in the cavity of the right glass sheet 7. The PLC controller 17 then determines that this state is smooth feeding. The light (infrared rays) is converted into a certain voltage through the circuit, and whether there is a foreign object blocking (that is, the carbon black powder is blocked) is detected by detecting the change in voltage. When the carbon black powder is blocked in the conveying pipe 5 and cannot be fed, the infrared rays emitted by the infrared emitting tube 13 are blocked by the accumulated carbon black powder and cannot be received by the infrared receiving tube 14. Then the PLC controller 17 determines that this state is feeding blockage and activates the buzzer 18 to alarm, so as to remind the staff to dredge the conveying pipe 5 in time.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
