Description

Technical Field

[0001] The utility model relates to a dust removal pipeline protection device, in particular to a dust removal pipeline impurity removal and dust cleaning device. Background Art

[0002] Gangue crushing is an essential step in coal mine paste filling systems. The crushing and transporting of gangue generates a large amount of dust, necessitating the installation of a dust collector 1. Gangue transported from underground is often mixed with numerous woven bags, plastic netting, and other debris. These debris are crushed along with the gangue. Due to their light weight, they are sucked into the hopper by the dust collector 1. During discharge, they can easily become entangled with the impeller of the discharger, causing blockage. Excessive dust accumulation in the hopper can affect dust removal effectiveness.

[0003] In addition, since the dust removal pipe is too long, dust and large particles are easily deposited, especially at some bends, resulting in poor airflow and affecting the dust removal effect.

[0004] If there are too many particles deposited in the pipeline, it will affect the dust removal effect. Cleaning the sediment in the dust removal pipeline requires dismantling the equipment, which will cost a lot of manpower and material resources, and even require personnel to enter the pipeline for cleaning, and the working conditions are very harsh. Utility Model Content

[0005] The purpose of the utility model is to provide a dust removal pipeline impurity removal and dust cleaning device to solve the problem of blockage caused by light debris entangled in the dust removal pipeline and the poor air flow caused by the deposition of large particles of dust.

[0006] The purpose of the utility model is achieved as follows: a dust collecting pipe is connected to the air inlet of the dust collector;

[0007] The dust collection duct impurity removal and dust cleaning device includes: dust collection duct, grate filter device, sedimentation chamber and gate;

[0008] The grate filter device is installed in the dust collecting pipe, and the impurities and dust in the dust collecting pipe are filtered through the grate filter device; a sedimentation chamber is installed at the lower end of the dust collecting pipe, and the sedimentation chamber is located at the lower end of the grate filter device; a gate is connected to the bottom of the sedimentation chamber.

[0009] The grate filter device has a "U"-shaped bracket, and an observation door is provided at the opening of the "U"-shaped bracket, including: a hinge, a handwheel, a slide, a grate and an observation door; one end of the observation door is connected to one end of the opening of the "U"-shaped bracket through a hinge, and the other end of the opening of the "U"-shaped bracket is connected to the observation door through a handwheel, and there is a handle on the observation door; there is a slide inside the "U"-shaped bracket, and the grate is inserted into the slide.

[0010] The grate has a U-shaped frame, which is the same as the U-shaped bracket. A filter is arranged in the U-shaped frame. A handle is connected to the flat end surface of the grate.

[0011] Beneficial effects: Due to the above solution, flexible debris entering the pipeline is filtered by the grate. When the grate is too full, the grate can be quickly replaced by simply opening the observation door without stopping the machine. The sedimentation chamber receives the grate filter device, which blocks large dust particles below. Large dust particles are deposited in the sedimentation chamber. By opening the lower gate of the sedimentation chamber, the deposited large dust particles are cleared and transferred for processing.

[0012] An inspection door and chute are installed in the grate filter unit to allow for quick installation and removal of the grate. Two to three spare grates are prepared. Flexible debris drawn from the gangue crushing system enters the pipeline and is blocked by the grate. Periodically, the inspection door is opened to check the amount of debris on the grate. If there is a large amount of debris, the grate is removed and replaced with a spare. The inspection door is closed and debris removed from the replaced grate.

[0013] Due to the establishment of the sedimentation chamber, the cross-sectional area here increases and the wind speed decreases. Large particles will settle here and fall into the sedimentation chamber. The deposited particles can be discharged by opening the gate at the bottom of the sedimentation chamber.

[0014] This simple, practical structure offers easy maintenance, allowing troubleshooting without stopping the equipment. The grate filter, settling chamber, and gate facilitate handling of both lightweight debris and large dust particles within the dust removal duct. This system is particularly suitable for applications where the material contains excessive amounts of flexible debris and the dust removal duct is long and has numerous bends.

[0015] When there are debris in the dust removal duct, it can be immediately processed without affecting production. It can also conveniently clean the dust particles deposited in the duct, solving the problem of blockage caused by light debris entangled in the discharger impeller and the problem of poor air flow caused by the accumulation of large particles of dust in the dust removal duct. The purpose of the utility model is achieved.

[0016] Advantages: The structure is simple and practical, low cost, easy to operate, and ensures the smooth progress of production.

[0017] This structure can trap debris sucked into the dust collector in the pipe and remove it promptly, preventing it from entering the dust collector hopper and clogging the dust discharge valve. It also makes it easier to clean dust deposited in the pipe, preventing excessive dust from affecting dust removal efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
