Description

Technical Field

[0001] The utility model belongs to the technical field of dust reduction pipelines, and in particular relates to a dust reduction pipeline for concrete production. Background Art

[0002] The utility model patent with the patent authorization announcement number CN217391907U discloses a dust reduction pipe for concrete production that is easy to install, including a pipe body, a dust hopper is fixedly connected to one side of the bottom end of the pipe body, a filter is fixedly arranged on one side of the inner wall of the dust hopper, and an electric telescopic rod is fixedly installed on one side of the top of the pipe body. The movable end of the electric telescopic rod extends to the inside of the pipe body and is fixedly connected with a cleaning brush. The utility model discloses a dust reduction pipe for concrete production that is easy to install. The electric telescopic rod pushes the cleaning brush up and down to perform preliminary cleaning on the filter, and then a plurality of nozzles spray high-pressure water columns to perform high-pressure washing on the filter, which can prevent the filter from being blocked by dust and thus affect the filtering efficiency. The two support rods are locked and fixed in two mounting seats by four fixing bolts and four threaded holes respectively, so as to realize the fixed installation of the dust reduction pipe. However, when the device is used, the dust particles will be broken by rubbing with the cleaning brush, so that the filter cannot achieve the filtering effect.

[0003] The purpose of the utility model is to provide a dust reduction pipe for concrete production, which solves the problem that the existing dust reduction pipe for concrete production will cause dust particles to be broken by rubbing with a cleaning brush, thereby making the filter screen unable to achieve a filtering effect, and the device is not convenient for efficient dust reduction treatment of dust of any height.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a dust reduction pipe for concrete production, including a hanging plate, a hanging rod is welded to the lower end of the hanging plate, a pipe is hinged to the lower end of the hanging rod, an adjustment mechanism is provided on the hanging plate, a fan is fixedly installed on the inner left part of the pipe, a collecting trough is detachably installed on the lower end of the pipe, a slide cylinder is slidably connected to the inside of the pipe, a filter screen is fixedly installed on the right end of the slide cylinder, and a vibration mechanism is provided on the slide cylinder.

[0005] The principle of the utility model is that when in use, the device is adjusted according to the height with high dust content, the cylinder is started, the cylinder drives the cylinder rod to extend, the cylinder rod drives the support block to move, the support block moves to make the connecting rod deflect, and then the angle of the pipeline changes under the support of the suspension rod, so that the height of the right end of the pipeline can be adjusted, so that the device is convenient for suction and dust reduction treatment at positions with different heights, and then the fan is started to suck air, so that the air is sucked into the pipeline from the right end of the pipeline and filtered by the filter screen, the airflow drives the fan blades to rotate, the fan blades drive the support shaft to rotate, the support shaft drives the baffle rod to rotate, the baffle rod rotates and contacts with the baffle block, slides on the surface of the baffle block, so that the baffle rod moves in the right direction, the baffle rod drives the support shaft to move right, the support shaft drives the support ring to move, the support ring drives the slide cylinder to move right, and then the guide block moves right to squeeze the spring, so that the baffle rod and the baffle block are misaligned, the spring resets the guide block to reset and collide with the pipeline, so that the slide cylinder drives the filter screen to vibrate, so that the dust on the filter screen is vibrated and detached, so that the filter screen is not easy to be blocked, and the filtering efficiency of the filter screen is ensured.

[0006] The beneficial effect of the utility model is that the supporting block is driven to move by the cylinder, thereby causing the connecting rod to deflect, thereby causing the angle of the pipeline to change under the support of the suspension rod, thereby allowing the height of the right end of the pipeline to be adjusted, making it convenient for the device to perform suction and dust reduction treatment at positions of different heights.

[0007] The fan draws air in, and the airflow drives the support shaft to rotate through the fan blades, which in turn causes the stop rod to rotate and the stop block to collide and slide, which in turn causes the slide cylinder to displace with the cooperation of the spring and the guide block, so that the slide cylinder can vibrate in the pipe, causing the dust on the filter to be vibrated off, making the filter less likely to be blocked, thereby ensuring the filtering efficiency of the filter.

[0008] Furthermore, the adjustment mechanism includes a support plate, a cylinder, a connecting sleeve, a limit pin, a support block, and a connecting rod. The support plate is welded to the lower end of the hanging plate, and the cylinder is fixedly installed to the left end of the support plate. The cylinder rod of the cylinder passes through the support plate and is slidably connected to the support plate. The outer side of the cylinder rod is slidably connected to the connecting sleeve, and the right end of the connecting sleeve is welded to the support block, and the support block is slidably connected to the hanging plate. The support block is driven to move by the cylinder, thereby causing the connecting rod to deflect, thereby causing the angle of the pipeline to change under the support of the hanging rod, thereby allowing the height of the right end of the pipeline to be adjusted, so that the device is convenient for suction and dust reduction treatment at positions with different heights.

[0009] Further, the connection sleeve is internally slidably connected with a limit pin, and the limit pin and the cylinder rod are connected by threads. By setting the limit pin, the connection sleeve and the cylinder rod are connected.

[0010] Furthermore, a connecting rod is hinged at the lower end of the support block, and the connecting rod is hinged to the pipeline. By setting the connecting rod, the change of the pipeline angle is controlled.

A support ring is fixedly installed inside the slide tube, a support shaft is installed inside the support ring through a bearing, a fan blade is arranged on the right outer side of the support shaft, a baffle is fixedly connected to the left outer side of the support shaft, a baffle is fixedly connected to the inner side of the slide tube, the baffle contacts the baffle, a guide rod is welded inside the pipe, a guide block is welded on the outer side of the slide tube, and a spring is arranged on the outer side of the guide rod. The fan draws air, and the airflow drives the support shaft to rotate through the fan blades, thereby causing the baffle to rotate and collide and slide with the baffle, thereby causing the slide tube to displace under the cooperation of the spring and the guide block, thereby causing the slide tube to vibrate in the pipeline, causing the dust on the filter to be vibrated off, making the filter not easy to be blocked, and ensuring the filtering efficiency of the filter.

[0012] Furthermore, the guide block is slidably connected to the guide rod, and the guide block is slidably connected to the pipeline. The guide block is provided to guide the movement of the slide cylinder.

[0013] Furthermore, one end of the spring is fixedly connected to the guide block, and the other end of the spring is fixedly connected to the pipeline. By providing the spring, the guide block is easy to reset. BRIEF DESCRIPTION OF THE DRAWINGS
