Description

Technical Field

[0001] This utility model belongs to the field of calcium oxide processing technology, and specifically relates to a calcium oxide powder feeding device. Background Technology

[0002] Calcium oxide (CaO), commonly known as quicklime, is an important inorganic chemical raw material widely used in construction, metallurgy, chemical industry, agriculture and other fields. The processing of calcium oxide mainly includes calcination, crushing and sieving. The calcium oxide powder feeding device is a system used to automatically transport calcium oxide powder from the storage container to the subsequent processing equipment (such as mixers, reaction vessels, etc.), and is an important piece of equipment for calcium oxide powder processing.

[0003] Existing calcium oxide powder feeding devices work by pouring calcium oxide powder into a storage container, then using a motor to drive a rotating shaft connected to it. This causes the bolts on the outer arc surface of the shaft to rotate, and the rotating spiral blades push the calcium oxide powder along the pipeline, thus feeding the calcium oxide powder. However, when feeding the calcium oxide powder stored in the storage container, gravity causes the powder to settle downwards, which may accumulate at the discharge port at the bottom of the storage container. This affects the smooth conveying of calcium oxide powder, requiring personnel to tap the storage container to refill it, which is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a calcium oxide powder feeding device. The dispersing paddle moves up and down repeatedly as it rotates back and forth around the vertical center of the hopper, quickly and evenly dispersing the material in the hopper, keeping the material in a loose state so that it can be smoothly fed in the future.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a calcium oxide powder feeding device, including a base frame, a support frame one on the base frame, a hopper on the support frame one, a conveying pipe between the hopper and the base frame, a support frame two on the base frame, a feeding pipe between the support frame two and the conveying pipe, a rotating seat at the top of the hopper, multiple sliding cylinders on the rotating seat, a sliding rod slidably mounted inside each sliding cylinder, and a dispersing paddle at the bottom of each sliding rod; a driving mechanism on the hopper for driving the movement of the dispersing paddle; a feeding hopper on the outside of the hopper, and a discharge hopper at the top of the feeding pipe.

[0006] As a further improvement of this utility model, a drive seat is provided on the upper surface of the hopper, an internal gear ring is provided inside the drive seat, and an adjusting screw is rotatably provided inside the sliding cylinder. A gear is fixedly sleeved on the upper end of each adjusting screw, and the gear is meshed with the internal gear ring. The adjusting screw is threadedly connected to the adjacent sliding rod. A motor is provided on the upper surface of the drive seat, and a linkage shaft is provided in the middle of the rotating seat. The output shaft of the motor is fixed to the linkage shaft by a coupling.

[0007] As a further improvement of this utility model, a rotating rod is rotatably arranged inside the conveying pipe, and a spiral blade is fixedly sleeved on the outside of the rotating rod. A motor is installed on the conveying pipe, and the output shaft of the motor is fixed to the rotating rod by a coupling.

[0008] As a further improvement of this utility model, a rotating shaft is provided inside the feeding pipe, and a spiral blade is fixedly sleeved on the outer arc surface of the rotating shaft. A motor is provided on the outside of the feeding pipe, and the output shaft of the motor is fixed to the rotating shaft by a coupling.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the output shaft of motor three drives the linkage shaft connected to it to rotate back and forth, which in turn drives the dispersing paddle on the lower side of the slide bar to rotate back and forth around the vertical center of the hopper, so as to quickly and evenly disperse the calcium oxide powder material in the hopper.

[0011] Secondly, during the rotation of the rotating seat, the gear at the top of the adjusting screw driven by the rotating seat moves back and forth around the vertical center of the hopper in an arc trajectory, quickly and evenly dispersing the material in the hopper, keeping the material in the hopper in a loose state so that the material can be smoothly fed in later.

[0012] Thirdly, the first motor operates, and the rotation of the first spiral blade causes the calcium oxide powder material falling into the conveying pipe to be transported from the inside of the conveying pipe into the inside of the feeding pipe. The output shaft of the second motor drives the shaft connected to it to rotate, and the rotation of the second spiral blade causes the calcium oxide powder material entering the feeding pipe to be transported to the uppermost side of the inside of the feeding pipe.

[0013] Fourth, the combination of conveying pipe and feeding pipe allows calcium oxide powder to be conveyed and fed stably and smoothly while avoiding dust generation. Attached Figure Description

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 2 , 4 As shown, the system includes a base frame 101, a support frame 102 on the base frame 101, a hopper 103 on the support frame 102, a conveying pipe 105 between the hopper 103 and the base frame 101, a support frame 206 on the base frame 101, a feeding pipe 107 between the support frame 206 and the conveying pipe 105, a rotating seat 201 at the top of the inside of the hopper 103, a plurality of sliding cylinders 202 on the rotating seat 201, a sliding rod 203 slidably disposed inside each sliding cylinder 202, and a dispersing paddle 204 disposed at the bottom end of each sliding rod 203.

[0022] like Figure 2 , 3As shown, a drive mechanism is provided on the hopper 103, which is used to drive the movement of the dispersing paddle 204; a drive seat 207 is provided on the upper surface of the hopper 103, and an internal gear ring 208 is provided inside the drive seat 207. Adjusting screws 205 are rotatably provided inside the sliding cylinders 202. Gears 206 are fixedly sleeved on the upper end of the adjusting screws 205. The gears 206 are meshed with the internal gear ring 208. The adjusting screws 205 are threadedly connected to the adjacent sliding rods 203 respectively; a motor 209 is provided on the upper surface of the drive seat 207, and a linkage shaft is provided in the middle of the rotating seat 201. The output shaft of the motor 209 is fixed to the linkage shaft by a coupling.

[0023] like Figure 2 , 4 As shown, a rotating rod 109 is rotatably mounted inside the conveying pipe 105, and a spiral blade 110 is fixedly sleeved on the outer side of the rotating rod 109. A motor 111 is mounted on the conveying pipe 105, and the output shaft of the motor 111 is fixed to the rotating rod 109 by a coupling. A rotating shaft 112 is rotatably mounted inside the feeding pipe 107, and a spiral blade 113 is fixedly sleeved on the outer arc surface of the rotating shaft 112. A motor 114 is mounted on the outer side of the feeding pipe 107, and the output shaft of the motor 114 is fixed to the rotating shaft 112 by a coupling.

[0024] like Figure 1 , 2 As shown, a feed hopper 104 is provided on the outside of the hopper 103, and a discharge hopper 108 is provided at the upper end of the feeding pipe 107.

[0025] When in use, the calcium oxide powder to be processed is poured from the feed hopper 104 into the inside of the hopper 103, and the calcium oxide powder is initially stored in the hopper 103.

[0026] The output shaft of motor 209 drives the connected linkage shaft to rotate reciprocally, which in turn drives the rotating seat 201 to rotate. This, in turn, causes the sliding rod 203 on the lower side of the sliding cylinder 202 to rotate reciprocally around the vertical center of the hopper 103. This, in turn, causes the dispersing paddle 204 on the lower side of the sliding rod 203 to rotate reciprocally around the vertical center of the hopper 103, rapidly and evenly dispersing the calcium oxide powder material within the hopper 103. During the rotation of the rotating seat 201, the gear 206 at the top of the adjusting screw 205 moves reciprocally around the vertical center of the hopper 103 in an arc trajectory. The gear 206's reciprocating movement around the vertical center of the hopper 103 in an arc trajectory further contributes to this effect. During operation, the meshing relationship between the gear 206 and the internal gear ring 208 drives the gear 206 to rotate, which in turn causes the adjusting screw 205 to rotate back and forth in an arc trajectory around the vertical center of the hopper 103. In turn, the thread relationship between the adjusting screw 205 and the slide rod 203 causes the slide rod 203 to move up and down in the back and forth rotation around the vertical center of the hopper 103. This causes the dispersing paddle 204 on the lower side of the slide rod 203 to move up and down in the back and forth rotation around the vertical center of the hopper 103, which quickly and evenly disperses the material in the hopper 103, keeping the material in the hopper 103 in a loose state so that the material can be smoothly fed in the future.

[0027] Operated by motor 111 and motor 114, calcium oxide powder falls from hopper 103 into conveying pipe 105. The output shaft of motor 111 drives the rotating rod 109 connected to it to rotate, which in turn drives the spiral blade 110 on the outer arc surface of the rotating rod 109 to rotate. The rotation of the spiral blade 110 causes the calcium oxide powder falling into the conveying pipe 105 to be conveyed into the feeding pipe 107. The output shaft of motor 114 drives the rotating shaft 112 connected to it to rotate, which in turn drives the spiral blade 113 on the outer arc surface of the rotating shaft 112 to rotate. The rotation of the spiral blade 113 causes the calcium oxide powder entering the feeding pipe 107 to be conveyed to the uppermost side of the feeding pipe 107, and finally discharged from the discharge hopper 108.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
