Description

Technical Field

[0001] The present application relates to the technical field of limestone powder production, and specifically to a dust suppression device for desulfurized limestone powder production. Background Art

[0002] Desulfurization limestone powder is a material used to remove sulfur dioxide from exhaust gas. Its main component is calcium carbonate, which has the characteristics of high-efficiency desulfurization. When it comes into contact with sulfur dioxide, it can react chemically to convert harmful gases into harmless substances, thereby protecting the atmospheric environment from pollution. During its production process, a large amount of dust will be generated. If it is not cleaned up in time, it will cause pollution to the air and the environment.

[0003] Application No. 202322057268.6 discloses a dust reduction device for the production of desulfurized limestone powder, including a device shell, a filter screen, a collecting box, a connecting block and an atomizing net, etc. By adding desulfurized limestone powder and grinding it with a grinding rod, qualified desulfurized limestone powder will pass through the holes of the material inspection plate and will be adsorbed by the water mist sprayed by the atomizing net when passing through the atomizing net area. Unqualified products will be isolated by the material inspection plate and fall into the collecting box under the action of gravity. This can solve the problem of dust generation during the production process and the problem of dirt accumulation affecting the production qualification rate and efficiency in subsequent production, thereby improving the work efficiency and quality. Moreover, by starting the dust suction fan, the desulfurized limestone powder dust generated during feeding will be sucked into the dust suction fan through the dust suction pipe. After a batch of materials is processed, the desulfurized limestone powder in the dust suction fan will be taken out for processing. Through this device, the subsequent cleaning trouble and material waste are solved, thereby improving the work efficiency and material utilization rate.

[0004] However, in use, there are the following defects:

[0005] Although an atomizing net is used to generate water mist to absorb the stone powder, thereby solving the dust problem, the atomizing net is set below the material inspection plate. During the atomizing adsorption process, the stone powder soaked in water will stick to the bottom of the material inspection plate. Over time, the holes of the material inspection plate may be clogged, thereby preventing the normal passage of limestone powder and affecting the continuous use efficiency of the device. Utility Model Content

[0006] The purpose of the present application is to provide a dust suppression device for the production of desulfurized limestone powder, which solves the problem proposed in the background technology that although an atomizing net is used to generate water mist to adsorb stone powder, thereby solving the dust problem, since the atomizing net is arranged below a material inspection plate, during the atomizing adsorption process, water-soaked stone powder will stick to the bottom of the material inspection plate, which may cause the holes of the material inspection plate to be clogged over time, thereby hindering the normal passage of limestone powder and affecting the continuous use efficiency of the device.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a dust reduction device for the production of desulfurized limestone powder, comprising a box body, a partition, a guide plate, a collecting trough and an atomizing nozzle, a filling port is opened and connected on the left side of the top of the box body, a ventilation slot is opened in the upper right corner of the inner side of the box body, and two layers of filter screens are detachably installed on the side wall of the ventilation slot, a partition is fixedly installed on the left side of the bottom of the ventilation slot, a crushing roller is movably installed between the lower left side wall of the partition and the inner left side wall of the box body, and guide plates are fixedly connected between the partitions on both sides of the crushing roller and the inner left side wall of the box body, a material picking plate is movably inserted and connected to the left side wall of the box body below the crushing roller, a collecting trough is laterally slidably connected to the bottom of the box body below the material picking plate, and a pulling slot is opened below the right side wall of the box body.

[0008] In this technical solution, the raw material of desulfurized limestone powder is added to the box body through the filling port. In order to prevent the generation of dust, the driving motor will be powered on and work at this time, exhausting air to the right side, thereby generating wind pressure at the filling port, sucking the dust into the box body or the ventilation slot, and opening the cleaning door to clean the ventilation slot after the end. The raw material reaches the crushing roller through the guide plate. After the driving motor is powered on, it drives the crushing roller to rotate, thereby crushing the raw material. The powder of suitable size will pass through the falling hole, while the powder of unqualified size will remain on the surface of the material inspection plate, and can be collected by pulling out the material inspection plate later, and poured into the filling port again for processing. The generation of dust can be reduced through the partition, water inlet pipe and atomizing nozzle. When the powder enters When the dust reaches the collecting tank below, the atomizing nozzle sprays the water in the water inlet pipe in an atomized state, and after combining with the dust, it falls back into the collecting tank. Due to the separation of the partition, the combination of dust and water mist can be prevented from sticking to the material inspection plate and blocking the falling hole, thereby ensuring the normal material discharge efficiency of the device. At the same time, the desulfurized limestone powder can be collected through the water-permeable membrane, the drain and the drawing groove. In the continuous spraying process of the atomizing nozzle, water will gradually accumulate in the collecting tank. The accumulated water is combined with the desulfurized limestone powder. At this time, a water-permeable membrane is provided, so that the water can leave the drain through the water-permeable membrane, thereby reducing the water accumulation capacity in the collecting tank. Subsequently, the collecting tank is pulled out of the drawing groove and simply dried to obtain the desulfurized limestone powder, thereby improving the production and collection efficiency of the device.

[0009] As an optional solution of the technical solution of the present application, a rectangular groove is opened on the right side of the bottom of the collecting tank, and a water-permeable membrane is detachably installed at the opening of the rectangular groove.

[0010] As an optional solution to the technical solution of the present application, a drainage channel is opened at the bottom of the box body below the rectangular groove, and the other end of the drainage channel is located on the right side wall of the box body below the pull-out groove.

[0011] As an optional solution of the technical solution of the present application, a water inlet pipe is fixedly connected between the left side wall of the partition and the inner right side wall of the box body, and a plurality of atomizing nozzles are evenly arranged at the bottom of the water inlet pipe.

[0012] As an optional solution of the technical solution of the present application, a drive motor is fixedly installed on the left side wall of the box body facing the left end of the crushing roller, and the rear end of the transmission shaft of the drive motor is fixedly connected to the crushing roller.

[0013] As an optional solution to the technical solution of the present application, an exhaust fan is fixedly installed above the right side wall of the box, and the exhaust fan is connected to the ventilation slot. A cleaning door is movably installed at the upper right corner of the surface of the box, and the cleaning door is connected to the ventilation slot.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can reduce the generation of dust through the partition, water inlet pipe and atomizing nozzle. When the powder enters the collection tank below, the atomizing nozzle sprays the water in the water inlet pipe in an atomized state, combines with the dust and makes it fall back into the collection tank. Due to the separation of the partition, the combination of dust and water mist can be prevented from sticking to the material inspection plate and blocking the drop hole, thereby ensuring the normal material discharge efficiency of the device.

[0016] 2. The present application can collect desulfurized limestone powder through a permeable membrane, a drainage channel and a pulling trough. During the continuous spraying of the atomizing nozzle, water will gradually accumulate in the collecting trough. The accumulated water is combined with the desulfurized limestone powder. At this time, a permeable membrane is provided so that the water can leave the drainage channel through the permeable membrane, thereby reducing the water accumulation capacity in the collecting trough. Subsequently, the collecting trough is pulled out of the pulling trough and simply dried to obtain the desulfurized limestone powder, thereby improving the production and collection efficiency of the device.
