Description

Technical Field

[0001] The utility model relates to the technical field of construction waste treatment equipment, in particular to a construction waste dust removal pipeline anti-blocking device. Background Art

[0002] At present, most of the pipelines in the construction industry are ordinary dust removal pipelines. The composition of construction waste is complex, the content of light materials is high, and the types and sizes of light materials vary. Therefore, the dust removal pipelines of wind selection equipment and environmental dust removal pipelines often inhale a large amount of light materials due to negative pressure, causing pipeline blockage, which requires a lot of manpower and material resources to clean up, and the cleaning process is more dangerous due to the confined space. During the dust removal process of wind selection equipment, some lighter light materials such as wood chips, plastic films, paper pieces, etc. will enter the bag dust collector along the dust removal pipeline with the dust-containing airflow. After being collected by the bag dust collector, they will be discharged through the unloading screw conveyor at the bottom of the bag dust collector and the external star-shaped ash discharge valve that matches it, causing the impurity content of the dust removal ash to be too high and the purity to decrease. Moreover, when the content of light materials is high, the light materials will be stuck in the gap between the spiral blades and the outer shell of the spiral conveyor, causing the spiral blades to fall off the main shaft, causing equipment failure, or the light materials will be stuck in the gap between the blades and the shell of the star-shaped ash discharge valve, causing the blades to stop rotating and the pipeline to be blocked.

[0003] In order to solve the above-mentioned problems, Chinese patent CN220160856U provides a dust collector, including a dust collecting body, which has a dust collecting chamber inside, and is provided with an air inlet and an air outlet connected to the dust collecting chamber; a feed pipe, which has a feeding channel inside, and a feed port and a discharge port connected to the feeding channel are formed at both ends, respectively, the discharge port is connected to the air inlet, and the feed port is used to supply materials to enter the feeding channel; a filter screen is arranged inside the feed pipe and located between the feed port and the discharge port, the filter screen blocks the feeding channel, and the filter screen has a plurality of mesh holes arranged at intervals, and the mesh holes penetrate along the flow direction of the material. In the above-mentioned prior art, during the process of conveying the material to the dust collecting body through the feed pipe, the light matter mixed in the dust is intercepted by the filter screen, and the dust can continue to be conveyed through the mesh holes of the filter screen, thereby realizing the separation of light matter in the material. Since the light matter is blocked, the risk of the internal structure of the dust collector being worn by the light matter, blockage and equipment failure is reduced. However, after a period of use, the mesh of the filter screen of the dust collector in the prior art is easily clogged, and it needs to be disassembled and cleaned regularly, which not only consumes manpower but also affects the production progress.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Embodiment 1:

[0022] Reference Figure 1 and Figure 2 As shown, a device for preventing dust removal pipes from being blocked by construction waste is improved in that: it comprises a shell, a ventilation duct and a turntable mechanism are installed inside the shell, the ventilation duct is arranged on the left side of the shell and is sealedly connected to the shell, the ventilation duct comprises an air inlet channel and an air outlet channel, the lower end of the air inlet channel extends out of the shell, and the upper end is placed in the shell, and the upper port of the air inlet channel is larger than its lower port; the upper end of the air outlet channel extends out of the shell, and the lower end is placed in the shell, the upper port of the air inlet channel extends out of the shell, and the lower port is placed in the shell, the upper port of the air inlet channel matches the lower port of the air outlet channel in size and corresponds in position to each other, and the lower port of the air outlet channel is larger than its upper port; the turntable mechanism comprises a filter disc 32, the filter disc 32 is placed between the air inlet channel and the air outlet channel and can rotate relative to the ventilation duct, the size of the filter disc 32 at least covers the upper port of the air inlet channel, and a light material discharge port 23 is provided at the lower right end of the shell.

[0023] In this embodiment, when working, the upper port of the air inlet channel is larger than its lower port, and the dust-containing air flows from the narrower lower port of the air inlet channel to the wider upper port, the airflow is gradually dispersed and the flow rate is gradually reduced, and the light matter in the air is also dispersed throughout the upper port of the entire air inlet channel, and is adsorbed below the filter disc 32 through the blocking of the filter disc 32, and the air with the light matter removed flows out through the air outlet channel and enters the subsequent equipment.

When the size of the filter disc 32 is larger than the size of the upper port of the air inlet channel, and its size can cover the upper port of the air inlet channel during the entire rotation process of the filter disc, the filter disc 32 can be set to rotate slowly at a constant speed.
