Description

Technical Field

[0001] This utility model relates to the technical field of pipeline inspection devices, specifically a blockage detection device for material conveying pipelines. Background Technology

[0002] In the rubber compounding process, especially in large-scale internal mixer systems of modern automated production, a lot of powder is automatically transported to the internal mixer through pipelines for compounding. Under normal circumstances, the material transport is smooth. However, there have been many instances where, due to valve or material abnormalities, material accumulates and blocks above the valve, preventing the material from being transported to the internal mixer. Since the material has already left the weighing scale, and the weighing scale is accurate, it is often difficult to detect the blockage in time. It can only be discovered during subsequent testing or weighing after compounding. By this time, a batch of defective products may have already been produced. Therefore, it is necessary to detect pipeline blockages in a timely manner and clean and eliminate the fault in order to improve the production qualification rate.

[0003] Chinese patent CN215916667U discloses a detection device for detecting pipe blockage, comprising a pipe, a support base mounted on the upper right side of the pipe, a base fixedly connected to the bottom of the support base, a connecting ring provided on the right end face of the pipe, a clamping block mounted on the left end of the pipe, a placement frame fixedly connected to the upper end face of the pipe, a detection mechanism embedded inside the placement frame, a drainage cavity mounted on the input end of the detection mechanism, a filtering mechanism and a stirring mechanism mounted inside the drainage cavity, the output end of the filtering mechanism being connected to the input end of the detection mechanism, the detection mechanism including an indicator fan blade mounted on the upper end face of the placement frame, a rotating shaft fixedly connected to the bottom end of the indicator fan blade, a bolt mounted on the bottom end of the rotating shaft, a sealing ring bonded to the upper end face of the bolt, and a rotating fan blade mounted in the middle of the rotating shaft.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent cannot repeatedly test or assist in loosening the powder inside the pipe.

[0006] Therefore, those skilled in the art have provided a material conveying pipeline blockage detection device to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a material conveying pipeline blockage detection device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A material conveying pipeline blockage detection device includes a conveying pipe, and further includes: a conveying device, a detection mechanism, and a quick adjustment device. The conveying device is installed on the upper side of the conveying pipe, the detection mechanism is installed on the left side of the conveying device, and the quick adjustment device is installed on the right side of the conveying device. The conveying device includes: a powder butterfly valve, a vertical pipe, and a maintenance pipe. One end of the powder butterfly valve is fixedly connected to the upper side of the conveying pipe, and the vertical pipe is fixedly connected to the end of the powder butterfly valve away from the conveying pipe. The maintenance pipe is fixedly installed on the left side of the vertical pipe. The detection mechanism includes: a filling block and a laser level gauge. The filling block is fixedly installed inside the maintenance pipe, and the laser level gauge is fixedly installed inside the filling block. The detection mechanism further includes: an auxiliary cleaning mechanism installed on the filling block.

[0010] Furthermore, the auxiliary cleaning mechanism includes: a support frame, a limiting frame, and a sliding plate. The support frame is fixedly installed on the filling block, the limiting frame is fixedly installed on the support frame, and the two sliding plates are slidably connected to the limiting frame from the side. A strip-shaped slot is provided in the middle of the sliding plate.

[0011] Furthermore, the filling block has multiple circular openings, and the end of the sliding plate away from the limiting frame is slidably connected to the circular openings;

[0012] Furthermore, a limiting rod is fixedly installed at one end of the support frame near the filling block, and the limiting rod is set in the strip slot;

[0013] Furthermore, the auxiliary cleaning mechanism also includes: a swing assembly, which is installed at the end of the support frame away from the filler block. The swing assembly includes: a geared motor, a crankshaft, and connecting rods. The geared motor is fixedly installed on the support frame, the crankshaft is rotatably connected to the support frame, the input end of the crankshaft is fixedly connected to the output shaft of the geared motor, and a plurality of connecting rods are rotatably connected to the crankshaft.

[0014] Furthermore, the end of the connecting rod away from the crankshaft is hinged to the end of the sliding plate away from the filler block;

[0015] Furthermore, the quick adjustment device includes: a fixed frame, a connecting frame, and a vertical rod. The two fixed frames are disposed on the right side of the vertical pipe, and the connecting frame is fixedly connected to the left side of the fixed frame. The connecting frame is located on the left side of the vertical pipe, and the two vertical rods are fixedly installed between the two fixed frames.

[0016] Furthermore, the quick adjustment device also includes: an irregularly shaped sliding frame, a radar level gauge, and fixing blocks. The irregularly shaped sliding frame is slidably connected to the vertical rod, the radar level gauge is fixedly installed on the side of the irregularly shaped sliding frame, and the two fixing blocks are threadedly connected to the front and rear sides of the irregularly shaped sliding frame. Tightening the fixing blocks fixes the irregularly shaped sliding frame to the vertical rod. The fixing blocks can be configured as screws.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a vertical pipe of the conveying device for inputting powder, a powder butterfly valve for opening and closing the channel between the vertical pipe and the conveying pipe, and a maintenance pipe for maintaining the powder butterfly valve and its upper vertical pipe. A filler block blocks the maintenance pipe to prevent powder from entering the maintenance pipe, which would lead to inaccurate powder conveying, reduced powder conveying, incorrect proportioning, and subsequent product abnormalities. A laser level gauge is used for the initial detection of whether there is blockage between the powder butterfly valve and the vertical pipe, and a radar level gauge is used for the secondary detection of whether there is blockage in the vertical pipe. This allows for multiple detections to determine whether there is blockage in the pipe and improves the detection accuracy. Loosening the fixing block of the quick adjustment device allows the irregular sliding frame to move up and down. The up and down movement of the irregular sliding frame drives the radar level gauge, which can quickly adjust the detection height to adapt to different types of powder. This facilitates the rapid adjustment of the radar level gauge to adapt to different types of powder and whether there is blockage at different conveying rates for the same type of powder.

[0018] 2. The rotation of the output shaft of the speed reducer motor of the swing assembly drives the crankshaft to rotate. The rotation of the crankshaft drives the connecting rod to rotate alternately. The alternating rotation of the connecting rod drives the sliding plate to slide alternately. The alternating sliding of the sliding plate loosens the powder back and forth, avoiding the accumulation of powder and causing blockage. This helps to loosen the powder in the pipeline.

[0028] The conveying device 2 is used to convey powder, the detection mechanism 3 is used to detect whether the powder is blocked, and the detection mechanism 3 can also help loosen the powder to avoid blockage.

[0032] The sliding plate 35 of the auxiliary cleaning mechanism slides back and forth on the filling block 31 to loosen the powder in the vertical pipe 22, reducing the probability of powder blockage between the vertical pipe 22 and the powder butterfly valve 21. The limiting frame 34 is used to limit the sliding of the sliding plate 35.

[0033] A limiting rod 38 is fixedly installed at one end of the support frame 33 near the filling block 31. The limiting rod 38 is set in the strip slot 36 and is used to limit the sliding of the sliding plate 35.
