Description

Technical Field

[0001] The utility model relates to the field of desulfurization equipment, in particular to a feeding device for a flue gas purification desulfurization equipment. Background Art

[0002] Flue gas desulfurization is a process for reducing the emission of harmful substances such as sulfur dioxide in flue gas. During coal combustion and industrial production processes, flue gas often contains high concentrations of sulfur dioxide, which has a serious impact on the environment and human health. Therefore, researching and developing efficient desulfurization technologies is of great significance for reducing sulfur dioxide emissions.

[0003] Before desulfurization, baking soda particles need to be ground into powder to improve their reactivity and efficiency in the desulfurization process. Currently, the operation is to manually pour bagged baking soda particles into a grinding machine, then repackage the ground baking soda powder and transport it to a desulfurization tower for desulfurization. However, during the transfer of baking soda between different equipment, dust will be generated and a part of the baking soda raw material will be lost. Summary of the Utility Model

[0004] In order to reduce the loss of baking soda raw materials during the processing before entering the desulfurization tower, the present application provides a feeding device for a flue gas purification desulfurization equipment.

[0005] The feeding device for a flue gas purification desulfurization equipment provided by the present application adopts the following technical solutions:

[0006] A feeding device for a flue gas purification desulfurization equipment includes a loss-in-weight feeder, a screw conveyor assembly, a grinding machine, a blower, and a conveying pipeline. The screw conveyor assembly is arranged below the loss-in-weight feeder. The loss-in-weight feeder is used to control the feeding amount. The screw conveyor assembly is used to transport the raw materials given by the loss-in-weight feeder to the inlet of the grinding machine. The outlet of the grinding machine is connected to the inlet of the blower. The outlet of the blower is connected to one end of the conveying pipeline. The other end of the conveying pipeline is used to connect to a desulfurization tower.

[0007] By adopting the above technical solutions, during the entire process of grinding and transporting baking soda raw materials to the desulfurization tower, the baking soda raw materials no longer need to be repackaged and transported twice, and all are transported by mechanical equipment. Therefore, the loss of baking soda raw materials during the processing before entering the desulfurization tower can be reduced.

[0008] Preferably, the loss-in-weight feeder includes a feed bin, a cover, a stirring motor, a stirring shaft, and stirring blades. The cover is installed at the top of the feed bin. The stirring motor is fixedly arranged on the top surface of the cover. The output shaft of the stirring motor extends into the interior of the feed bin and is coaxially fixed with the stirring shaft. The stirring blades are fixedly arranged on the outer wall of the stirring shaft. The cover is provided with a feeding port and an exhaust port.

[0009] By adopting the above technical solution, the stirring motor drives the stirring shaft to drive the stirring blades to stir the materials in the bin, so that the raw materials are first broken up and enter the screw transportation assembly, which is convenient for the next step of grinding into powder.

[0010] Preferably, a baffle is hinged at the feeding port, and a filter screen is provided at the air outlet.

[0011] By adopting the above technical solution, during the stirring process after feeding, dust will come out from the feeding port and the air outlet. Therefore, the baffle can block the feeding port to prevent dust overflow, and the dust-proof net can block some dust without affecting ventilation.

[0012] Preferably, two receiving plates are provided on the bottom wall of the cover body. The receiving plates are L-shaped. One end of the receiving plate is fixed on the bottom wall of the cover body, and the other end of the receiving plate is used to support the bag containing the raw materials. The two receiving plates respectively support both sides of the bottom end of the bag.

[0013] By adopting the above technical solution, during the process of the operator pouring the bagged raw materials into the feeding port, the bag can be placed on the two receiving plates, without constantly applying force to the bag, and the process of pouring the raw materials can be easier.

[0014] Preferably, it further includes a bag-breaking component, which is used to cut the bottom of the bag placed on the two receiving plates.

[0015] By adopting the above technical solution, after the bag is placed on the receiving plate, part of the feeding port has been blocked. Cutting the bag can reduce the waste of raw materials in the bag and the amount of dust coming out of the feeding port.

[0016] Preferably, the bag-breaking component includes a connecting rod and a blade. The two ends of the connecting rod are respectively fixed on the blade and the stirring shaft. The moving path of the blade passes through the bottom end of the bag, and the two receiving plates are respectively located on both sides of the moving path of the blade.

[0017] By adopting the above technical solution, after the bag is placed, drive the stirring motor. The stirring shaft rotates to drive the connecting rod and the blade to rotate together. The blade passes through the bottom end of the bag to cut the bag, and then the stirring motor stops running. The operator shakes the bag to pour out all the raw materials.

[0018] Preferably, a number of conical positioning thorns are provided on the side surface of the receiving plate for supporting the bag.

[0019] By adopting the above technical solution, the positioning thorns can prevent the bag from directly falling into the bin.

[0020] The technical effects of the present utility model are mainly reflected in the following aspects:

[0021] 1. During the entire process of transporting the baking soda raw material to the desulfurization tower after grinding, the baking soda raw material no longer needs to be bagged and transported twice, and all transportation is carried out by mechanical equipment. Therefore, the loss of the baking soda raw material during the processing before entering the desulfurization tower can be reduced.

[0022] 2. By setting two receiving plates in the present utility model, when the operator pours the bagged raw material into the feeding port, the bag can be placed on the two receiving plates, and there is no need to continuously apply force to the bag, making the process of pouring the raw material easier.

[0023] 3. By setting a bag-breaking component in the present utility model, since the bag body blocks part of the feeding port after being placed on the receiving plate, cutting the bag body can reduce the waste of the raw material in the bag body and reduce the amount of dust coming out of the feeding port.

The screw conveying assembly 2 is arranged below the loss-in-weight feeder 1. The loss-in-weight feeder 1 is used to control the feeding amount. The screw conveying assembly 2 is used to transport the raw materials given by the loss-in-weight feeder 1 to the inlet of the grinding mill 3. The outlet of the grinding mill 3 is connected to the inlet of the blower 4. The outlet of the blower 4 is connected to one end of the conveying pipeline 5. The other end of the conveying pipeline 5 is used to connect to the desulfurization tower.

[0031] Reference Figure 1 During the entire process of grinding and transporting the baking soda raw materials to the desulfurization tower, the baking soda raw materials do not need to be bagged and transported for the second time. All transportation is done by mechanical equipment, so the loss of baking soda raw materials during the processing before entering the desulfurization tower can be reduced.

[0032] Reference Figure 1 The screw conveying assembly 2 is mainly composed of a spiral blade, a motor and an outer sleeve. The spiral blade is the main component for conveying materials in the outer sleeve, and the motor provides power. It belongs to the existing mature technology and will not be repeated here.

[0033] Reference Figure 1 and Figure 2 The loss-in-weight feeder 1 includes a silo 11, a cover 12, a stirring motor 13, a stirring shaft 14 and a stirring blade 15. The cover 12 is installed on the top of the silo 11, the stirring motor 13 is fixedly arranged on the top surface of the cover 12, the output shaft of the stirring motor 13 extends into the silo 11 and is coaxially fixed with the stirring shaft 14, the stirring blade 15 is fixedly arranged on the outer wall of the stirring shaft 14, and a feeding port 121 and an exhaust port 122 are opened on the cover 12.

[0034] Reference Figure 1 and Figure 2 The stirring motor 13 drives the stirring shaft 14 to drive the stirring blades 15 to stir the materials in the silo 11, so that the raw materials are first broken up and enter the screw conveying assembly 2, which is convenient for the next step of grinding.

[0035] Reference Figures 1-3 A baffle 16 is hinged at the feeding port 121, and a filter screen is provided at the exhaust port 122.

[0036] Reference Figures 1-3 After the materials are added, during the stirring process, dust will come out from the feeding port 121 and the exhaust port 122, so the baffle 16 can block the feeding port 121 to prevent dust from overflowing, and the dustproof net 1221 can block some dust without affecting ventilation.

[0037] Reference Figure 2 and Figure 3, there are two receiving plates 17 on the bottom wall of the cover body 12. The receiving plates 17 are arranged in an L shape. One end of the receiving plate 17 is fixed on the bottom wall of the cover body 12, and the other end of the receiving plate 17 is used to support the bag body containing raw materials. The two receiving plates 17 respectively support both sides of the bottom end of the bag body.

[0038] Refer to Figure 2 and Figure 3 , during the process of the operator pouring the bagged raw materials into the feeding port 121, the bag can be placed on the two receiving plates 17, without constantly applying force to the bag, and the process of pouring raw materials can be easier.

[0039] Refer to Figure 2 and Figure 3 , it further includes a bag-breaking component 6. The bag-breaking component 6 is used to cut the bottom of the bag body placed on the two receiving plates 17. After the bag body is placed on the receiving plate 17, part of the feeding port 121 has been blocked.

[0040] Refer to Figure 2 and Figure 3 , the bag-breaking component 6 includes a connecting rod 61 and a blade 62. Both ends of the connecting rod 61 are respectively fixed on the blade 62 and the stirring shaft 14. The moving path of the blade 62 passes through the bottom end of the bag body. The two receiving plates 17 are respectively located on both sides of the moving path of the blade 62. After the bag body is placed, drive the stirring motor 13, the stirring shaft 14 rotates to drive the connecting rod 61 and the blade 62 to rotate together. The blade 62 passes through the bottom end of the bag body to cut the bag body, and then the stirring motor 13 stops running. The operator shakes the bag body to pour out all the raw materials.

[0041] Refer to Figure 2 and Figure 3 , there are several conical positioning thorns 171 on the side surface of the receiving plate 17 for supporting the bag body. The positioning thorns 171 can prevent the bag body from directly falling into the feed bin 11.

[0042] Of course, the above are only typical examples of this application. In addition, this application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by this application.
