Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a Venturi dust collector with a chip conveyor. Background Art

[0002] Wet Scrubber is an air purification device, mainly used to remove particulate matter, aerosol and gaseous pollutants from the gas. It achieves the purpose of air purification by contacting the gas with water or other liquids, so that the particulate matter and pollutants settle into the liquid. Wet Scrubber is suitable for processing high temperature, high humidity and high dust concentration gas flow.

[0003] The basic working principle of a wet venturi dust collector includes the following steps:

[0004] Air inlet: Dust-laden gas is introduced into the wet Venturi dust collector from the air inlet;

[0005] Spray system: In a wet venturi dust collector, water or other liquids are sprayed into the gas through a spray system. This can be done through nozzles, water curtains or other forms of spray equipment;

[0006] Contact with liquid: The sprayed liquid mixes with the gas, and the pollutants and particles come into contact with the liquid to form a particle-droplet complex;

[0007] Sedimentation and separation: The particle-droplet complex formed settles in the wet venturi dust collector. This can be accomplished by centrifugal force, gravity or other separation mechanisms;

[0008] Purified gas discharge: After being treated by the wet venturi dust collector, the purified gas is discharged into the atmosphere through the outlet.

[0009] As mentioned above, the wet dust collector technology uses the negative pressure of the power fan and the spray system formed by the water pump to make the liquid form a uniform water film. The airflow carrying smoke and flammable and explosive dust enters the separator (Venturi tube) evenly in the tangential direction and needs to pass through the throat of the Venturi tube equipped with washing liquid spray. The gas is rapidly accelerated at the throat of the Venturi tube, the liquid is atomized, and the relative movement of the airflow and liquid makes them fully mixed. The smoke or flammable and explosive dust, pollutants and liquid gather, and then the impurities collected by the pollutants are removed by the liquid. The collected impurities will flow into the main body of the chip conveyor from the drain port, and the sediment in the dust collector body is resolved (removed). And through the precipitation method, the impurities in the circulating water in the dust collector body are precipitated, so that the impurity content of the upper liquid is reduced, which greatly improves the use efficiency and replacement time of the circulating water.

[0010] In the prior art, there is a published patent number: 201922323105.1, and the name is: A sludge separation water tank for a wet dust collector: A sludge separation water tank for a wet dust collector is disclosed, including a water tank, on which an automatic sludge scraping mechanism, an automatic frothing mechanism and an automatic oil skimming mechanism are provided; the automatic sludge scraping mechanism includes a sludge scraping reduction motor, a sludge scraping sprocket, a sludge scraping chain, a sludge scraping plate and a mud unloading scraper, and an inclined surface is formed on one side of the water tank, and the sludge scraping sprocket includes a first sprocket located at the upper end of the inclined surface, a second sprocket located at the lower end of the inclined surface, and a third sprocket located at the bottom of the end of the water tank away from the inclined surface, and the sludge scraping reduction motor is connected to the first sprocket; the automatic frothing mechanism includes a frothing reduction motor, a frothing sprocket, a frothing chain, a frothing plate and a frothing unloading scraper; the automatic oil skimming mechanism is arranged at the liquid level position of the water tank, and the automatic oil skimming mechanism includes an oil skimming steel belt and an oil skimming motor. The utility model integrates water storage, circulating water filtering, sludge sedimentation, automatic water replenishment, automatic sludge scraping, automatic foam skimming and automatic oil skimming.

[0011] In combination with the above-mentioned patent disclosure, the current wet Venturi dust collector still has the following problems during operation:

[0012] First, the gas containing impurities is sprayed only through the spray system structure so that the impurities are mixed with the liquid and then precipitated. However, the impurities are not sprayed completely, resulting in a high impurity rate in the discharged gas.

[0013] Secondly, in the existing publicly available scraping and chip removal technology, when the scraper blade scrapes large particles or encounters other obstacles or forces, important parts in the machine are easily damaged.

[0014] Therefore, we designed a Venturi dust collector with a chip conveyor to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0044] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments.

[0045] Embodiment 1

[0046] Reference Figure 1 A Venturi dust collector with a chip conveyor is mainly composed of a dust collector body 1 and a chip conveyor body 2. The bottom of the dust collector body 1 and the chip conveyor body 2 are fixed as an integral structure by bolts. When working, water and dust inside the dust collector body 1 will flow into the inside of the chip conveyor body 2 from the drain port below the dust collector body 1.

[0047] Among them, the dust collector is installed with an electric control box with an electric control system. The electric control system is made to form continuous control and overall control for the entire equipment, and is also made according to various requirements.

[0048] In this embodiment, the dust removal body 1 includes a feed assembly 101 and a power assembly 102. At least two spray structures 103 and at least two demisting structures 104 are installed on the dust removal body 1 between the feed assembly 101 and the power assembly 102, and each spray structure 103 and each demisting structure 104 are installed inside the dust removal body 1 in an interlaced manner, and the gas inside the dust removal body 1 is subjected to multiple filtration and dust removal. This multiple filtration interlaced filtration is more efficient, and the dust content of the filtered gas is low:

[0050] Among them, the power component 102 includes a power fan 1021 and an electrical box, and the power fan 1021 and the electrical box are electrically connected. The dust removal body 1 also includes a dust removal bin 105 arranged inside. A spray 1031, a drainage cone 1051, a drainage port, a first-level defogger 1041, a second spray 1032, a second-level defogger 1042, and a power fan 1021 are installed in sequence inside the venturi tube 1011 and the dust removal bin 105. A ventilation baffle for installing a power fan is also connected above the dust removal bin 105, and an exhaust port 106 is opened on the dust removal bin 105 at the top of the power fan 1021.

[0051] It should be noted that both the primary demisting 1041 and the secondary demisting 1042 in this embodiment adopt a demisting layer structure, wherein the demisting layer is used to capture and remove suspended particles or droplets in the gas. The demisting layer of the spray tower usually uses some specific materials that can effectively capture particulate matter and withstand wet and corrosive environments.

[0052] The following are some materials commonly used in spray tower demisting layers:

[0053] Plastic fillers: Plastic fillers are usually used to construct the defogging layer, such as polypropylene (PP) or polyvinyl chloride (PVC). These plastics are corrosion-resistant and have good tolerance to wet environments;

[0054] Metal fillers: Stainless steel, aluminum alloy and other metal fillers are also often used to make demisting layers. These metals have good corrosion resistance and are suitable for handling some corrosive gas environments;

[0055] Ceramic fillers: Ceramic fillers are also used in some special gas purification applications because they have better resistance to high temperatures and corrosion;

[0056] Fiberglass: Fiberglass products can also be used to make demisting layers because they have certain corrosion resistance.

[0057] In this embodiment, the material of the demisting layer is usually selected depending on the specific application environment, gas composition and operating conditions. When selecting the material of the demisting layer, factors such as corrosion resistance, wear resistance, mechanical strength and the effect on gas flow need to be considered. The demisting layer of suitable material is selected in the above manner.

[0058] In this embodiment, the first spray 1031 and the second spray 1032 use two branch water pipe structures connected to the water pump 7;

[0059] Among them, a spray 1031 is arranged above the venturi tube 1011, the drainage cone 1051 is communicated with the venturi tube 1011, the drainage cone 1051 is communicated with the drain port, the first-level demisting cone 1041 is communicated with the drainage cone 1051, and a drain port is opened at the bottom of the drainage cone 1052, the second spray 1032 is used to clean and remove dust from the demisting layer of the first-level demisting 1041, and a second-level demisting 1042 is arranged above the second spray 1032 for further demisting, and the clean air after the second-level demisting 1042 enters the power fan 1021, and is then discharged to the outside of the exhaust port 106.

[0060] More specifically, in this embodiment Figure 1 In the process, under the negative pressure of the power fan 1021, the dust is sucked from the air suction port 1012 and then evenly enters the venturi tube 1011 after passing through the air suction port 1012. When entering the venturi tube 1011, the dust is removed by the first spray 1031. The water and dust are rapidly accelerated, the liquid is atomized, and the relative movement of the airflow and the liquid makes them fully mixed. After mixing, the liquid will flow into the drainage cone 1051 along the venturi tube 1011. The airflow will follow the direction of the power fan 1021 and pass through the first-stage mist removal 1041 to intercept the dust for the second time, and then the second-stage spray 1032 will be used to wash it again. The dust concentration will drop again. The generated water mist will pass through the second-stage mist removal 1042 and the clean air treated with water and mist will be discharged from the exhaust port 106. The liquid and the treated dust of the first spray 1031 and the second spray 1032 will flow from the drainage cone into the drainage port and into the chip conveyor body 2.

[0061] In this embodiment, refer to Figure 2The chip conveyor body 2 includes a driving assembly 201 and a scraping assembly 202, and a safety clutch 4 is connected between the driving assembly 201 and the scraping assembly 202; the driving assembly 201 includes an electric reducer 2011 and a sprocket, and the driving assembly 201 includes an electric reducer 2011, an outer sprocket set 2012 and an inner sprocket set 2013; a safety clutch and a sprocket linkage shaft 9 are installed between the outer sprocket set 2012 and the inner sprocket set 2013, a reducer chain 2014 is mounted on the outer sprocket set, and a scraping chain 2021 is mounted on the inner sprocket set 2013;

[0062] The scraper assembly 202 includes a scraper chain 2021 and scraper plates 2022 equidistantly installed on the scraper chain 2021 , and the scraper plates 2022 are detachably connected to the scraper chain 2021 .

[0063] It should be noted that there are two ways to install the electric reducer 2011: one is Figure 2 One is to install it from above. Figure 4 Way of side installation;

[0064] The slideway (guide structure 3) of the scraper chain 2021 is also divided into two types: one is Figure 2-3 The inner chain slideway 301 is used. Figure 4 The method comprises the steps of: using the inner chain pulley 302. Both methods can be used.

[0065] In this embodiment, the installation method of the electric reducer 2011 and the guide structure 3 is as follows: Figure 2 The way:

[0066] Reference Figure 2-3 The electric reducer 2011 in the chip conveyor body 1 drives the outer sprocket set 2012 to work when it is running (rotating); the power is transmitted through the outer sprocket transmission of the outer sprocket set 2012, the reducer chain 2014, and the connection of the safety clutch 4, and the power is transmitted to the inner sprocket set 2013 inside the scraper body 1 through the sprocket linkage shaft 9401 in the center of the safety clutch 4, driving the mud scraping chain 2021 on the inner sprocket set 2013 to perform transmission work.

[0067] Among them, refer to Figure 2-3 In the invention, the safety clutch 4 is installed on the transmission connection between the transmission sprocket outer sprocket group 2012 and the inner sprocket group 2013 between the reducer chain 2014 and the scraper chain 2021. The purpose of such installation is that when the scraper blade 2012 scrapes large particles or encounters other obstacles or forces during operation, the safety clutch 4 will break, disengage or slip, thereby automatically stopping the transmission of the clutch to protect important parts in the machine from damage.

[0068] More specifically, Figure 2 The power of the inner sprocket set 2013 of the chip conveyor body 1 is transmitted to the scraper chain 2021, and the scraper chain 2021 is fixed to the corresponding position through the installation position of the upper inner sprocket and the lower inner sprocket of the inner sprocket set 2013 without affecting the transmission and operation. Figure 2 The inner chain slide guide structure 3 forms a running track for the scraper chain 2021 inside the chip conveyor body 1.

[0069] The chain slide is Figure 2 The inner chain slideway 301 is divided into three layers, namely, the upper, middle and lower layers. The upper slideway is used to fix the upper scraper chain 2021 in the corresponding position to prevent the scraper chain 2021 from running off, tilting, and thus deviating. The middle slideway is used to adjust and fix the spacing between the upper and lower scraper chains 2021. The lower slideway is used to adjust the distance between the scraper plate 2022 and the bottom of the chip conveyor body 2, so that the dust and impurities deposited at the bottom of the chip conveyor body 2 are scraped away for chip removal.

[0070] The chip conveyor body 2 further includes a scraper bin 203 on which a driving assembly 201 and a scraper assembly 202 are installed, and a material vehicle 204 for collecting dust is installed outside the scraper bin 203 .

[0071] Reference Figure 2 In the figure, the scraper assembly 202 includes a scraper chain 2021 and scraper plates 2022 equidistantly installed on the scraper chain 2021. As the scraper chain 2021 runs (rotates), it drives the scraper plates 2022 installed on the scraper chain 2021. The scraper plates 2022 send the dust and impurities at the bottom of the chip conveyor body 1 into the ash discharge port and are collected together in the material discharge vehicle 204.

[0072] Reference Figure 5 In the figure, the components of the scraper blade 2022 are rubber plate 20221, bolt 20222, scraper support plate 20223, pressure plate 20224, and nut 20225. The scraper support plate 20223 is the main support plate, which is fixed on the scraper chain 2021. The function of the pressure plate 20224 is to clamp the rubber plate 20221 between the pressure plate 20224 and the scraper support plate 20223, and fix it (tighten) with bolts 20222 and nuts 20225. The rubber plate 20221 will rub against the bottom of the chip conveyor body 1 during operation. The use of rubber material will avoid damage to the bottom paint surface during friction. Rubber material also avoids irregular dust to prevent it from getting stuck or stopping operation. The components of the scraper blade 2022 can also be replaced, increased, or reduced without affecting the function, thereby reducing the overall loss of the scraper assembly 202.

[0073] It should be noted that Figure 2In the embodiment, the chip conveyor body 2 further comprises a water pump 7 arranged at the connection of the dust removal body 1, a filter screen 8 is mounted on the outer side of the bottom of the water pump 7, and a water replenishment float 5 is arranged inside the scraper bin 203;

[0074] The function of the filter 8b012 is to intercept large dust particles and impurities to prevent them from entering the water pump 7b011 area and affecting the normal use of the water pump 7;

[0075] The scraper bin 203 is provided with a water replenishing float 5, a chip conveyor body 1, Figure 1 The function of the water replenishment float 5b014 inside is to ensure the water level in the chip conveyor body 1, and the function of the drain valve b013 is to provide convenience when replacing water.

[0076] More specifically, the dust removal bin 105 is provided with a first inspection door on one side of the first-stage defogger 1041 and the second-stage spray 1032, a second inspection door is provided on one side of the second-stage defogger 1042, and a third inspection door is provided on one side of the power fan 1021, so as to facilitate the inspection of the defogger structure and the spray structure.

[0077] Embodiment 2

[0078] Reference Figure 4 The structure of the second embodiment is basically the same as that of the first embodiment, and the main difference is that:

[0079] Chain slide Figure 4 In the middle installation method, the inner chain pulley 302 is used to guide the chain slideway, and the electric reducer 2011 is installed on the side; the installation position is different, and the style of the electric reducer 2011 used is also different.

[0080] Compared with the first embodiment, the method of guiding the chain slideway by the inner chain pulley 302 is simpler in structure. When in use, it is more flexible and convenient to adjust the distance between the bottom of the scraper bin 203 and the scraper chain 2021 according to the needs. However, the guiding of the scraper chain 2021 by the inner chain pulley 302 alone has the phenomenon of poor scraping stability, and is only suitable for the chip conveyor body 1 with less sludge deposition.

[0081] Compared with Example 2, Example 1 has a relatively complicated structure, but the inner chain slide 301 is divided into three pairs of upper, middle and lower layers of the scraper chain 2021 for guiding and limiting. Compared with Example 1, the slide operation of the scraper chain 2021 is more stable and is suitable for use regardless of whether the sludge deposition is more or less.
