Description

Technical Field

[0001] This utility model relates to the field of air dust removal technology, specifically a low-energy dust collector device. Background Technology

[0002] Dust collectors, also known as dust removal and purification equipment or particulate matter capture devices, are important equipment in modern industrial environmental governance systems. They are key environmental protection devices that separate dust from flue gas or air to achieve air purification or material recovery. Their core function is to effectively capture particulate pollutants generated in industrial production, combustion processes, or daily life, such as smelting dust, mineral crushing dust, fuel combustion fly ash, and suspended particles in living areas, through physical, chemical, or electrical forces. This reduces air pollution and protects human health. Dust collectors have advantages such as high dust removal efficiency, flexible use, and stable operation, and are widely used in dust purification in various industrial fields such as mining, cement, and building materials.

[0003] However, current dust collectors have the following drawbacks during use: as the usage time increases, dust gradually accumulates on the dust collector's filter screen, causing a decrease in dust removal efficiency and an increase in power consumption. In existing technologies, the problem of dust collector clogging is mostly solved by periodically cleaning the filter screen, which is time-consuming, labor-intensive, inefficient, and cannot clean the dust collector in the first place when it is clogged.

[0004] For example, Chinese utility model patent application number CN202321629212.7, filed on June 26, 2023, describes a waste gas dust collector, including a dust collector body with a fixed mesh on one side inside the body. This waste gas dust collector, by using filter plates, effectively increases the filtration of smaller dust particles, enhancing the dust removal efficiency and allowing dust particles of various sizes to be filtered. In contrast, this prior art uses multiple filter screens and plates to filter waste gas, but it cannot clean the clogging of the screens or plates, leading to a gradual decrease in filtration efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a low-energy dust collector device that can solve the problem of dust collector filters not being able to be cleaned in time when they are clogged.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-energy dust collector device, comprising: an axially through-type cylinder, an air inlet end and an air outlet end corresponding to the air inlet end installed inside the cylinder, a dust filter screen installed at the air outlet end, an air inlet pipe passing through the air inlet end inside the cylinder, an induction plate located between the air inlet end and the air outlet end being slidably connected to the inner wall of the cylinder, the air inlet pipe passing through the induction plate, a scraper tightly attached to the dust filter screen being fixedly installed at one end of the air inlet pipe located between the induction plate and the air outlet end, and a driving component for rotating the scraper when the induction plate slides between the air inlet end and the induction plate.

[0007] Preferably, the air inlet end includes an air inlet plate fixed to the inner wall of the cylinder and a vent hole opened on the air inlet plate, and the air inlet pipe is rotatably connected to the air inlet plate.

[0008] Preferably, the air outlet includes an air outlet plate fixed to the inner wall of the cylinder and an air outlet channel formed on the air outlet plate.

[0009] Preferably, the outer edge of the air outlet plate has a tapering slope facing the center of the air outlet plate, and a dust storage groove is formed between the tapering slope and the inner wall of the cylinder.

[0010] Preferably, the dust filter is fixedly installed inside the air outlet channel.

[0011] Preferably, the scraper includes a scraping tip that contacts the dust filter and a mounting end that is fixed to the air intake pipe.

[0012] Preferably, a guide slope is formed on the mounting end to disperse the airflow in the intake pipe.

[0013] Preferably, the driving component includes a sleeve located between the sensing plate and the air intake plate. The sleeve is fixed on the sensing plate and sleeved on the outside of the air intake pipe. The outside of the air intake pipe is provided with a spiral groove. The inner wall of the sleeve is provided with a guide protrusion that cooperates with the spiral groove. A reset spring is installed between the sensing plate and the air intake plate. A guide rod passing through the sensing plate is fixedly installed on the air intake plate. When the sleeve slides along the outside of the air intake pipe, it drives the air intake pipe and the scraper to rotate through the spiral groove and the guide protrusion.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The low-energy dust collector device can monitor the clogging status of the dust filter in real time. When the dust filter is clogged to a certain extent, it will automatically drive the scraper to rotate on the surface of the dust filter, thereby scraping off the dust on the surface of the dust filter to unclog the dust filter.

[0016] (2) This low-energy dust collector device does not require additional electronic sensing modules. It utilizes the increased air pressure inside the dust collector when the dust filter is clogged as the trigger condition and power source for the scraper, which not only ensures the stable operation of the system, but also significantly reduces the manufacturing and installation costs of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides a technical solution: a low-energy dust collector device, comprising: an axially penetrating cylindrical body 1, an air inlet end 2 and an air outlet end 3 corresponding to the air inlet end 2 installed inside the cylindrical body 1; the air inlet end 2 includes an air inlet plate 2-1 fixed to the inner wall of the cylindrical body 1 and a vent hole 2-2 opened on the air inlet plate 2-1, the vent hole 2-2 serving to balance the air pressure inside the cylindrical body 1; the air outlet end 3 includes an air outlet plate 3-1 fixed to the inner wall of the cylindrical body 1 and an air outlet channel 3-2 opened on the air outlet plate 3-1; a dust collector filter screen 4 is fixedly installed inside the air outlet channel 3-2; and an air inlet pipe 5 passing through the air inlet plate 2-1 is provided inside the cylindrical body 1. The air pipe 5 is rotatably connected to the air inlet plate 2-1. The air inlet plate 2-1 can prevent the air pipe 5 from moving axially, so that the air pipe 5 can only rotate and cannot move axially. The inner wall of the cylinder 1 is sealed and slidably connected to the sensing plate 6 located between the air inlet plate 2-1 and the air outlet plate 3-1. The air inlet pipe 5 passes through the sensing plate 6. The sensing plate 6 can slide outside the air inlet pipe 5. The air inlet pipe 5 can be rotatably connected to the sensing plate 6. A scraper 7 that is close to the dust removal filter screen 4 is fixedly installed at one end of the air inlet pipe 5 located between the sensing plate 6 and the air outlet plate 3-1. A drive component 8 is provided between the air inlet plate 2-1 and the sensing plate 6 to drive the scraper 7 to rotate when the sensing plate 6 slides.

[0025] Furthermore, the outer edge of the air outlet plate 3-1 forms a converging inclined surface 3-3 facing the center of the air outlet plate 3-1, and a dust storage groove 3-4 is formed between the converging inclined surface 3-3 and the inner wall of the cylinder 1. The air outlet plate 3-1 can also be detachably fixed to the inner wall of the cylinder 1 by means of threads or snap fasteners, so as to facilitate cleaning the dust inside the dust storage groove 3-4.

[0026] Furthermore, the scraper 7 includes a scraping tip 7-1 that contacts the dust filter screen 4 and a mounting end 7-2 that is fixed to the air intake pipe 5. A guide slope 7-3 is formed on the mounting end 7-2 to disperse the airflow of the air intake pipe 5. The airflow impacts the guide slope 7-3 and is guided along the guide slope 7-3.

[0027] Furthermore, the driving component 8 includes a sleeve 8-1 located between the sensing plate 6 and the air intake plate 2-1. The sleeve 8-1 is fixed on the sensing plate 6 and sleeved on the outside of the air intake pipe 5. The outside of the air intake pipe 5 is provided with a spiral groove 8-2. The inner wall of the sleeve 8-1 is provided with a guide protrusion 8-3 that cooperates with the spiral groove 8-2. A reset spring 8-4 is installed between the sensing plate 6 and the air intake plate 2-1. The reset spring 8-4 is used to push the sensing plate 6 to reset when the dust filter screen (4) is unobstructed. A guide rod 8-5 passing through the sensing plate 6 is fixedly installed on the air intake plate 2-1. The function of the guide rod 8-5 is to prevent the sensing plate 6 from rotating during the sliding process, thereby avoiding affecting the cooperation of the spiral groove 8-2 and the guide protrusion 8-3. When the sleeve 8-1 slides along the outside of the air intake pipe 5, it drives the air intake pipe 5 to rotate through the spiral groove 8-2 and the guide protrusion 8-3. The rotation of the air intake pipe 5 drives the scraper 7 to rotate and scrape the dust on the dust filter screen 4.

[0028] Working principle: Gas is transported through the inlet pipe 5 to the dust filter screen 4 for dust removal and filtration, and then discharged through the outlet channel 3-2. When the dust filter screen 4 is blocked, the gas cannot be discharged well from the outlet channel 3-2. The air intake of the inlet pipe 5 is greater than the air exhaust of the outlet channel 3-2, which causes the air pressure between the sensing plate 6 and the dust filter screen 4 to increase, pushing the sensing plate 6 to slide. When the sensing plate 6 slides, the guide protrusion 8-3 on the inner wall of the sleeve 8-1 slides along the spiral groove 8-2, thereby driving the inlet pipe 5 to rotate. The rotation of the inlet pipe 5 drives the scraper 7 to scrape off the dust on the filter screen 4 and push the dust into the dust storage tank 3-4.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
