Description

Technical Field

[0001] The utility model relates to the technical field of calcium-based dry-process desulfurizing agent production, in particular to a raw material proportioning device for calcium-based dry-process desulfurizing agent production. Background Art

[0002] Calcium-based dry desulfurizers are materials used for flue gas desulfurization. Their primary component is calcium, and they perform desulfurization through a dry process. Through a process involving limestone calcination, hydration, and a desulfurization reaction, sulfur dioxide is removed from the flue gas and converted into calcium sulfate. This desulfurizer is highly efficient, environmentally friendly, and economical, making it widely used in industries such as steel mills, coking plants, and glass factories. Production of calcium-based dry desulfurizers requires a mixing device to mix the raw materials in a specific proportion.

[0003] After the existing proportioning device puts various raw materials into the mixing barrel according to the proportion, the raw materials are likely to remain in the proportioning barrel, which is inconvenient for the staff to clean. If the raw materials are not cleaned thoroughly, the accuracy of the next proportion will be affected. Utility Model Content

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Example 1

[0043] See Figure 1-4A raw material proportioning device for producing a calcium-based dry desulfurizer comprises a main body component 1, the main body component 1 comprising: a mixing drum 11, a feeding frame 12 symmetrically arranged on the top of the mixing drum 11; a proportioning mechanism 13, connected to the top of the feeding frame 12; a cleaning component 2 is provided on the mixing drum 11 and the feeding frame 12, the cleaning component 2 comprising: a bracket 211, provided on the top of the mixing drum 11; a water storage bucket 21, provided on the top of the bracket 211; a water pump 22, connected to the bottom of the water storage bucket 21; a water inlet pipe 221, which passes through the mixing drum 11; a water pump 221, connected to the bottom of the water storage bucket 21; a water pump 221, connected to the bottom of the water storage bucket 21; a water pump 221, connected to the mixing drum 1 ... Connected to the bottom of the water pump 22, the input end of the water inlet pipe 221 is connected to the water tank; the frame 23 is fixedly connected to one end of the feed frame 12 close to the center of the mixing drum 11; the telescopic hose 24 is symmetrically and through-connected to the outer wall of the water storage bucket 21; the tube body 25 is through-connected to the output end of the telescopic hose 24, and the other end of the tube body 25 passes through the top of the frame 23; the nozzle 26 is through-connected to the bottom of the tube body 25; the moving mechanism 27 is arranged on the water storage bucket 21 and the telescopic hose 24. The moving mechanism 27 includes: a motor 271 mounted on the top of the water storage bucket 21; a reciprocating screw 272 fixedly connected to the top output end of the motor 271; a threaded block 273 threadedly connected to the reciprocating screw 272; connecting pipes 274 symmetrically disposed on the outer side walls of the threaded block 273; and sleeves 275 fixedly connected to the outer side walls of the telescopic hose 24. The sleeves 275 are fixedly connected to one end of the connecting pipes 274. A solenoid valve 3 is connected through the frame 23 and is located between the feed frame 12 and the nozzle 26.

[0044] During use, the staff adds various raw materials into the proportioning mechanism 13 respectively, and the proportioning mechanism 13 releases a certain amount of raw materials. The raw materials fall into the mixing drum 11 through the feeding frame 12 for subsequent operations. After the materials inside the mixing drum 11 are taken out, the staff uses the cleaning component 2 to clean the inside of the feeding frame 12: the staff starts the water pump 22, and the water pump 22 draws the water source in the water tank connected to the water inlet pipe 221 into the water storage barrel 21, and the water is output from the water storage barrel 21 to the telescopic hose 24. The water in the telescopic hose 24 passes through the pipe body 25 and is sprayed out by the nozzle 26. The nozzle 26 cleans the feeding frame 12. The interior is flushed. During flushing, the moving mechanism 27 realizes the up and down reciprocating movement of the nozzle 26, increasing the flushing area of the nozzle 26 and enhancing the cleaning effect: the staff starts the motor 271 at the same time as the water pump 22. The motor 271 drives the reciprocating screw 272 to rotate. The threaded block 273 threaded on the reciprocating screw 272 drives the connecting pipe 274 to move up and down. Since the connecting pipe 274 is fixedly connected to the sleeve 275 on the telescopic hose 24, the connecting pipe 274 drives the pipe body 25 to move up and down, and the nozzle 26 at the bottom of the pipe body 25 is flushed up and down, achieving a better cleaning effect. When the proportioning mechanism 13 is proportioning and outputting raw materials, the solenoid valve 3 is in a closed state to prevent the raw materials from contacting the nozzle 26, reducing the proportioning accuracy and easily causing the nozzle 26 to clog. When it is necessary to clean the feed frame 12, the staff controls the solenoid valve 3 to open, which facilitates the nozzle 26 to flush the interior of the feed frame 12. The aforementioned proportioning mechanism 13 includes: a weighing system, such as an electronic scale, responsible for proportioning and metering the powders; a conveying system, such as a powered conveying mechanism, responsible for transporting the proportioned powders to their destination; and a control system, such as an electrical control system, responsible for controlling and managing the entire system. All of these are conventional technologies, and as long as they can achieve the proportioning of the raw materials, the specific structure will not be detailed here.

[0045] Example 2

[0046] On the basis of the first embodiment, an auxiliary function is added.

[0047] See Figure 1-4 The feed frame 12 and the bottom of the frame 23 both have inclined surfaces. A waterproof cover 251 is fixedly connected to the top of the frame 23, and the tube 25 is slidably connected to the inside of the waterproof cover 251. A protective tube 4 is fixedly connected to the top of the water storage bucket 21. The protective tube 4 is mounted outside the motor 271 and the reciprocating screw 272. The protective tube 4 has a through slot for the connecting tube 274 to move.

[0048] The inclined surfaces at the bottom of the feed frame 12 and the frame body 23 accelerate the falling speed of the raw materials while preventing the wastewater after the nozzle 26 is flushed from staying in the frame body 23 and the feed frame 12, thereby affecting the cleaning effect. Since the tube body 25 can move up and down, the waterproof cover 251 at the contact part between the tube body 25 and the frame body 23 prevents water from splashing out from the contact part, affecting the cleanliness of the operating environment. When the motor 271 drives the reciprocating screw 272 to rotate, the external protective tube 4 protects the reciprocating screw 272 to prevent the telescopic hose 24 from contacting the reciprocating screw 272 when the tube body 25 moves, causing wear on the telescopic hose 24, reducing the service life of the device, and greatly reducing the safety of operation.

[0049] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
