[0001] This utility model relates to the field of calcium carbide furnace raw material processing, specifically a closed conveying device for feeding raw material into a calcium carbide furnace. Background Technology

[0002] The calcium carbide furnace is the main equipment for producing calcium carbide. Inside the furnace, the high temperature generated by the electric arc melts the furnace charge, causing a reaction that produces calcium carbide. Because the reaction temperature reaches over 2000℃, most refractory materials cannot withstand such high temperatures. Therefore, the furnace volume must be larger than the reaction space. In other words, a layer of furnace charge should be left between the reaction zone and the furnace lining to protect the lining.

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.

[0018] like Figure 1-4 As shown, this utility model provides a technical solution: a closed conveying device for feeding raw materials in a calcium carbide furnace, including a guide cylinder 1. The outer surface of the guide cylinder 1 is equipped with a feeding component 2 and a dust suppression component 3. The feeding component 2 includes an arc-shaped plate 201, a flow guide hood 202, and a support rod 203. The arc-shaped plate 201 is hinged to the upper surface of the guide cylinder 1. The guide cylinder 1 enables the transportation of raw materials, thereby facilitating subsequent processing of the raw materials. At the same time, the arc-shaped plate 201 enables the feeding of raw materials, thereby facilitating subsequent feeding by workers.

[0019] The flow guide hood 202 is installed on the upper surface of the guide cylinder 1. The flow guide hood 202 can guide the flow of materials, thereby ensuring the normal conveying of subsequent materials. The support rod 203 is installed on the upper surface of the guide cylinder 1. The other end of the support rod 203 is fixedly connected to the fixing cover 204. The fixing cover 204 can guide the material feeding to a certain extent, thereby facilitating the subsequent processing of the material.

[0020] The dispensing component 2 also includes a guide plate 205, which is installed inside the guide cylinder 1. A motor 207 is installed in the guide cylinder 1. The output end of the motor 207 is fixedly connected to the other end of the stirring blade 206. Through the operation of the motor 207, the stirring blade 206 can be driven to rotate. Then, the guide plate 205 guides the flow of materials, so that the stirring blade 206 can realize the conveying of raw materials and ensure the normal use of subsequent raw materials.

[0021] The dispensing component 2 also includes two inclined plates 208, both of which are installed inside the guide cylinder 1. The inclined plates 208 are triangular in shape and can guide the raw materials to a certain extent, thereby preventing residues from appearing inside the guide cylinder 1.

[0022] The dispensing component 2 also includes a cylinder 209, which is installed inside the guide cylinder 1. A slide rod 210 is slidably connected inside the cylinder 209. One end of the slide rod 210 is fixedly connected to a circular plate 211, and a spring 212 is installed between the circular plate 211 and the cylinder 209. The other end of the slide rod 210 is fixedly connected to a horizontal plate 213. A column 214 is fixedly connected to the outer surface of the horizontal plate 213, and the outer surface of the column 214 contacts the outer surface of the arc plate 201. Through the contact between the column 214 and the arc plate 201, and with the spring 212, the slide rod 210 can be provided with a certain restoring ability, so that the arc plate 201 can be in a closed state, thereby preventing dust leakage.

[0023] The dust suppression component 3 also includes a port 301, which is located on the upper surface of the guide cylinder 1. A fan 302 is installed inside the port 301. By operating the fan 302, dust inside the guide cylinder 1 can be extracted. The airflow from the fan 302 can then guide the dust to a certain extent, making it easier to clean the dust later.

[0024] The dust suppression assembly 3 also includes a conveyor belt 303 and a motor 305. The conveyor belt 303 is installed on the upper surface of the guide cylinder 1. A connecting pad 304 is installed on the outer surface of the conveyor belt 303. The connecting pad 304 has a certain degree of adhesion, which enables it to adsorb dust and facilitates subsequent dust cleaning.

[0025] The motor 305 is mounted on the upper surface of the guide cylinder 1. The output end of the motor 305 is fixedly connected to the drive wheel 306. The outer surface of the conveyor belt 303 is fixedly connected to the driven wheel 307. The driven wheel 307 and the drive wheel 306 are connected by a belt 308. The operation of the motor 305 can drive the drive wheel 306 to rotate. The transmission connection between the drive wheel 306 and the driven wheel 307 can realize the rotation of the conveyor belt 303, which facilitates the subsequent cleaning of dust.

[0026] The dust suppression assembly 3 also includes a scraper 309 and a collection plate 310. The scraper 309 is installed on the upper surface of the guide cylinder 1. The outer surface of the scraper 309 is in contact with the outer surface of the connecting pad 304, which can scrape off the dust. The bottom surface of the collection plate 310 is installed on the upper surface of the guide cylinder 1. The scraped dust will enter the interior of the collection plate 310, which will facilitate subsequent operation by the staff.

[0027] When processing the raw materials, the section to be processed is first placed inside the guide cylinder 1 from the fixed cover 204. The section will contact the arc plate 201. Using the weight of the section itself, the arc plate 201 can be opened. During the opening of the arc plate 201, the slide rod 210 will slide, thereby the spring 212 will be pulled open under pressure. Then the column 214 will disengage from the arc plate 201, thus the arc plate 201 will be opened, and the section will fall into the guide cylinder 1. Then the motor 207 is started, and the output end of the motor 207 carries... The rotating impeller 206 guides the flow of materials in the process section. The dust generated during the flow is drawn by the fan 302 and sent to the surface of the connecting pad 304, where the dust adheres. As the conveyor belt 303 rotates, the scraper 309 scrapes off the dust from the surface of the connecting pad 304, thus treating the dust and preventing environmental pollution and waste of raw materials during transportation.
