Description
Technical Field
[0001] The utility model relates to the field of workshop dust collectors, in particular to a dust collector for a concrete production workshop. Background Art
[0002] The dust collector in the concrete production workshop is a high-efficiency bag dust collector. It relies on filter bags made of fiber filter materials. More importantly, it purifies the gas through the dust layer formed on the surface of the filter bag. Its dust removal efficiency can reach more than 99.99%. This equipment is developed on the basis of absorbing advanced experience of similar foreign equipment and combining specific conditions at home and abroad.
[0003] The existing dust collector in concrete production workshop can efficiently remove harmful substances such as dust and exhaust gas generated in various industrial production processes, ensuring the environmental sanitation of the production workshop and the health of workers. However, when cement is dried and dehydrated during concrete production, the temperature entering the kiln is as high as 100 to 150 degrees Celsius, and the material temperature rises to 600 to 900 degrees Celsius during the carbonate decomposition stage. If high-temperature air and dust are allowed to enter the dust collector, the temperature of the internal components of the dust collector will be too high and cause damage, reducing the service life of the dust collector. Therefore, it is urgently needed to design a dust collector that can cool down. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a dust collector for a concrete production workshop to solve the technical problem of excessively high temperature of the dust collector.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dust collector for a concrete production workshop, comprising a dust collector body, an ash hopper is arranged below the dust collector body, an air inlet is opened on one side of the ash hopper, an air inlet duct is connected to the surface of the air inlet, an air cooler is arranged on the top of the air inlet duct, and a fan is arranged on one side of the air cooler.
[0006] By adopting the above technical solution, dust and part of the air are sucked into the air intake duct by the negative pressure of the first turbine fan. At this time, the air refrigerator transmits cold air to the air intake duct through the fan to cool down the part of air and dust.
[0007] Furthermore, a filter cloth bag is arranged inside the dust collector body, and a pulse device is arranged on the top of the filter cloth bag.
[0008] By adopting the above technical solution, when the pulse device is activated, compressed air is ejected at high speed through the blowpipe, inducing the surrounding air to enter the filter cartridge and eject it quickly from the inside to the outside, blowing off the dust on the outer surface of the filter cartridge. The dust then falls into the ash hopper, making the filter bag cleaner and increasing the service life of the filter bag.
[0009] Furthermore, an air outlet duct is arranged on one side of the top of the dust collector body, and a second turbine fan is arranged on the outside of the air outlet duct.
[0010] By adopting the above technical solution, the second turbine fan can guide the purified air to be discharged from the air outlet duct, provide a guiding effect for the clean gas, and improve the working efficiency of the dust collector.
[0011] Furthermore, the air intake duct has a Z-shaped structure, and a first turbine fan is provided at the first bend.
[0012] By adopting the above technical solution, the first turbine fan is equipped with a small high-speed rotating mechanism to generate a high-speed airflow, and then the dust-containing air is sucked into the equipment. When meeting the high-speed airflow, the dust particles and the airflow produce relative movement, thereby being separated and filtered, removing most of the solid particles in the gas, making the gas discharged from the dust collector cleaner.
[0013] Furthermore, a through groove is provided on one side of the bottom of the ash hopper, a sewage pipe is connected to the bottom of the through groove, and a fan is provided at one end of the sewage pipe.
[0014] By adopting the above technical solution, the solid particles discharged from the dust collector can be discharged through the sewage pipe and will not be retained in the dust collector, so that the garbage in the dust collector can be cleaned up in time, and the powder in the dust collector will not be allowed to float in the air again, thereby improving the working efficiency of the dust collector.
[0015] Furthermore, the three inner surfaces of the ash hopper are all inclined structures.
[0016] By adopting the above technical solution, the inclined structure can prevent dust accumulation and allow the dust to slide naturally along the inner wall of the ash hopper under the action of gravity, which is not only conducive to the falling of dust, but also can avoid dust accumulation in the ash hopper to the greatest extent.
[0017] Furthermore, the outer surfaces of the air outlet pipe and the air inlet pipe are both provided with a sound insulation layer, and the material of the sound insulation layer is asbestos board.
[0018] By adopting the above technical solution, the density of the asbestos board is high and the surface of the asbestos board is smooth, which can effectively isolate the noise of the dust collector, prevent the noise of the dust collector from interfering with the surrounding environment, and reduce the most direct harm of noise to the human body.
[0019] In summary, the utility model mainly has the following beneficial effects:
[0020] 1. The utility model uses an air refrigerator. First, dust and part of the air are sucked into the air intake duct by the negative pressure of the first turbine fan. At this time, the air refrigerator transmits cold air to the air intake duct through the fan to cool down the air and dust. The cooled dust and air can reduce damage to the machine and extend the service life of the dust collector.
[0021] 2. The utility model provides a sound insulation layer. In the bag dust collector, the asbestos board can be used to wrap or cushion the noise-generating components, such as the fan or the air flow channel, to reduce the radiation and propagation of noise. The provision of the sound insulation layer can effectively reduce the transmission of the noise in the dust collector to the outside world, thereby reducing the harm of noise to the human body.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0028] The following describes an embodiment of the utility model based on its overall structure.
[0029] Embodiment 1:
[0030] A dust collector for a concrete production workshop, such as Figure 1-Figure 4As shown, it includes a dust collector body 1, a ash hopper 4 is arranged at the bottom of the dust collector body 1, an air inlet 5 is opened on one side of the ash hopper 4, the surface of the air inlet 5 is connected to an air inlet duct 11, the top of the air inlet duct 11 is connected to an air refrigerator 13, and a fan 14 is arranged on one side of the air refrigerator 13. Dust and part of the air are sucked into the air inlet duct 11 by the negative pressure of the first turbine fan 8. At this time, the air refrigerator 13 transmits cold air to the air inlet duct 11 through the fan 14 to cool down the part of the air and dust. The cooled air and dust enter the dust collector, which greatly extends the service life of the dust collector.
[0031] See also Figure 1 , Figure 2 A filter bag 2 is arranged inside the dust collector body 1, and a pulse device 3 is arranged on the top of the filter bag 2. When the pulse device 3 works, compressed air is ejected at high speed through the blowing pipe, inducing the surrounding air to enter the filter cartridge, and ejected quickly from the inside to the outside, blowing off the dust on the outer surface of the filter cartridge, and the dust then falls into the ash hopper 4, making the filter bag 2 cleaner, increasing the service life of the filter bag, reducing the use cost of the dust collector, and optimizing the structure of the dust collector.
[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 An air outlet duct 10 is arranged on one side of the top of the dust collector body 1, and a second turbine fan 9 is arranged on the outer side of the air outlet duct 10. The second turbine fan 9 can guide the purified air to be discharged from the air outlet duct 10, providing a guiding effect for the clean gas and improving the working efficiency of the dust collector.
[0033] See also Figure 2 The air inlet duct 11 is in a Z-shaped structure, and a first turbine fan 8 is provided at the first bend. The first turbine fan 8 has a built-in small high-speed rotating mechanism to generate a high-speed airflow, and then the air containing dust is sucked into the equipment. When meeting the high-speed airflow, the dust particles and the airflow produce relative movement, so that they are separated and filtered, and most of the solid particles in the gas are removed, so that the gas discharged from the dust collector is cleaner, the air is cleaner, and the pollution to the environment is reduced.
[0034] See also Figure 1 , Figure 3 A through groove 12 is provided on one side of the bottom of the ash hopper 4, and a sewage pipe 6 is connected to the bottom of the through groove 12. A fan 7 is provided at one end of the sewage pipe 6. The solid particles discharged from the dust collector can be discharged through the sewage pipe 6 and will not be retained in the dust collector, so that the garbage in the dust collector can be cleaned up in time, and the powder in the dust collector will not be dispersed in the air again, which improves the working efficiency of the dust collector, avoids the operation of secondary cleaning, and improves the convenience of use of the dust collector.
[0035] See also Figure 1 , Figure 2 The three inner sides of the ash hopper 4 are all inclined structures. The inclined structure can prevent dust accumulation and allow the dust to naturally slide down along the inner wall of the ash hopper 4 under the action of gravity, which is not only conducive to the falling of dust, but also can avoid the accumulation of dust in the ash hopper 4 to the greatest extent, avoid manual cleaning of the dust inside the ash hopper 4, and improve the convenience of cleaning the ash hopper 4.
[0036] Embodiment 2:
[0037] See also Figure 2 , Figure 4 The outer surfaces of the air outlet duct 10 and the air inlet duct 11 are both provided with a sound insulation layer 15, and the material of the sound insulation layer 15 is asbestos board. The density of the asbestos board is relatively high, and the surface of the asbestos board is smooth, which can effectively isolate the noise of the dust collector and prevent the noise of the dust collector from interfering with the surrounding environment, thereby reducing the most direct harm of noise to human hearing, allowing us to stay away from high-decibel noise interference and protect our hearing.
[0038] The implementation principle of the utility model is as follows: first, dust and part of the air are sucked into the air intake duct 11 by the negative pressure of the first turbine fan 8. At this time, the air refrigerator 13 transmits cold air to the air intake duct 11 through the fan 14 to cool down the part of the air and dust. The cooled dust and air enter the filter bag 2 through the air intake duct 11, and the filter bag 2 filters the dust. The pulse device 3 cleans the filter bag to prevent the filter bag 2 from being blocked. The filtered dust falls into the ash hopper 4, and the dust in the ash hopper 4 enters the drain pipe 6 through the through groove 12. The dust in the drain pipe 6 is discharged into the dust collector under the guidance of the force of the fan 7. At the same time, the filtered air is discharged from the air outlet duct 10 under the guidance of the second turbine fan 9.
[0039] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.
