Description

Technical Field

[0001] This utility model relates to the technical field of slag powder production equipment, and in particular to a slag powder spiral collecting device. Background Technology

[0002] Although slag is a byproduct of blast furnace ironmaking, it plays an important role in concrete and cement production. Slag powder is mainly used as an admixture in cement and as an additive in ready-mixed concrete. Its function is to improve the early strength of cement and concrete and improve certain properties of concrete (such as workability, early strength, and heat of hydration).

[0003] In the production process of slag powder, the slag needs to be crushed and then the powder needs to be collected using a collection device. For example, a dust collector for slag powder production disclosed on the China Patent Network (announcement number CN214515280U) introduces air containing powder into the device and uses electrostatic adsorption to adsorb the powder, and then uses water spraying to collect the dust.

[0004] This method results in the collected slag powder containing a large amount of moisture. To make it usable directly, a drying process is required, which wastes water resources. Furthermore, different types of concrete require different particle sizes of slag powder, so it is necessary to differentiate the particle size of the slag powder. This collection method can only collect the powder and does not have the ability to screen the powder. Utility Model Content

[0005] To overcome the problem that most collected slag powder contains a large amount of moisture, requiring an additional drying process to reach a level suitable for direct use, which wastes water resources, and lacks particle size screening capabilities.

A fixing frame is provided on the top of the second separation cylinder, and the fixing frame is fixedly connected to the second separation cylinder.

[0009] Preferably, the vibration assembly includes a first drive motor, a drive block, and a movable frame. The first drive motor is located above the fixed frame, and the drive block is located at the bottom of the fixed frame. The drive block is fixedly connected to the output end of the first drive motor, and the movable frame is located above the collection bag.

[0010] Preferably, the bottom of the drive block is provided with interlocking beads, which are equidistant from each other around the circumference, and the upper part of the movable frame is provided with interlocking holes that cooperate with the interlocking beads.

A connecting pipe 4 is provided on one side of the first separating cylinder 1, and a fan 3 is provided on one side of the connecting pipe 4. The second separating cylinder 2 is provided on one side of the first separating cylinder 1. The fan 3, the connecting pipe 4, the first separating cylinder 1, and the second separating cylinder 2 are interconnected. A collecting bag 5 for collecting powder is provided inside the second separating cylinder 2, and a vibration assembly is provided above the collecting bag 5. The first separating cylinder 1... A discharge seat 7 is provided at the bottom of the second separation cylinder 2, and an auger 8 is provided inside the auger 8 to convey the powder. By setting up the first separation cylinder 1 for cyclone separation, the larger particle size material is separated, and the smaller particle size material enters the second separation cylinder 2 with the air and is then filtered and collected by the collection bag 5. The vibration component applies a small amplitude high frequency vibration to the collection bag 5 to shake off the material attached to the collection bag 5 for collection. The discharge seat 7 collects the two different particle sizes of material and conveys them out of the device in two directions through the auger 8.

[0025] Please see Figure 2In this embodiment, a spiral guide plate 102 is provided on the inner side of the first separation cylinder 1 to guide air to move spirally downward along the inner wall of the first separation cylinder 1. A discharge pipe 101 is provided on the inner side of the first separation cylinder 1, and a feed pipe 103 is provided on one side of the first separation cylinder 1. The feed pipe 103 introduces air containing powder into the first separation cylinder 1, and under the guidance of the spiral guide plate 102, the air moves spirally downward along the inner wall of the first separation cylinder 1. The powder with a larger particle size leaves from the bottom channel of the first separation cylinder 1 under the action of gravity, and the powder with a smaller particle size enters the discharge pipe 101 with the air and leaves the first separation cylinder 1.

[0026] Please see Figure 3 In this embodiment, a partition plate 201 is provided on the inner side of the second separation cylinder 2. The partition plate 201 is fixedly connected to the bottom end of the collection bag 5. A fixing frame 202 is provided on the top of the second separation cylinder 2. The fixing frame 202 is fixedly connected to the second separation cylinder 2. Air containing small-diameter powder enters the bottom space of the partition plate 201 and moves from the bottom to the top of the second separation cylinder 2. Under the filtering effect of the collection bag 5, the powder is blocked and retained inside the collection bag 5.

[0027] Please see Figure 4 In this embodiment, the vibration assembly includes a first drive motor 6, a drive block 205, and a movable frame 203. The first drive motor 6 is disposed above the fixed frame 202, and the drive block 205 is disposed at the bottom of the fixed frame 202. The drive block 205 is fixedly connected to the output end of the first drive motor 6. The movable frame 203 is disposed above the collection bag 5. The bottom of the drive block 205 is provided with interlocking beads 206, which are equidistantly arranged around the circumference. The movable frame 203 has an opening at its top that connects to the interlocking beads 206. The matching round hole 204 is provided with guide rods 207 on both sides of the movable frame 203. The guide rods 207 pass through the fixed frame 202 and are slidably connected to the fixed frame 202. A spring 208 is provided on the outside of the guide rod 207. The first drive motor 6 causes the drive block 205 to rotate, so that the matching round ball 206 continuously separates from and re-fits with the matching round hole 204, thereby continuously pushing the movable frame 203 to move downward and upward under the elastic action of the spring 208, generating a small high-frequency vibration on the collecting bag 5, shaking off the powder.

[0028] Please see Figure 5In this embodiment, a collection chamber 701 is provided above the discharge seat 7. The collection chamber 701 is connected and communicates with the first separation cylinder 1 or the second separation cylinder 2. Discharge ports 702 are provided at the bottom of both ends of the discharge seat 7. A second motor 801 is provided at one end of the auger 8. A partition block 703 is provided on the inner side of the discharge seat 7. The spiral blades of the auger 8 on both sides of the partition block 703 are in opposite directions. The collection chamber 701 collects the two particle sizes of powder collected by the first separation cylinder 1 and the second separation cylinder 2. The second motor 801 drives the auger 8 to rotate. The auger 8 with opposite spiral directions at both ends generates conveying forces in opposite directions, conveying the powder out from the discharge port 702.

[0029] When the device is in use, the connecting pipe 4 is connected to the crushing device. The blower 3 generates air to blow the powder into the first separation cylinder 1. The feed pipe 103 introduces air containing powder into the first separation cylinder 1, and under the guidance of the spiral guide plate 102, the air moves spirally downward along the inner wall of the first separation cylinder 1. The larger particle size powder leaves from the bottom channel of the first separation cylinder 1 under the action of gravity, while the smaller particle size powder enters the discharge pipe 101 with the air and leaves the first separation cylinder 1. The air containing the small particle size powder enters the bottom space of the partition plate 201 and moves from the bottom to the top of the second separation cylinder 2. Under the filtering action of the collection bag 5, the powder... The powder is blocked inside the collection bag 5. The first drive motor 6 causes the drive block 205 to rotate, causing the fitting ball 206 to continuously separate from and fit into the fitting hole 204, thereby continuously pushing the movable frame 203 downward and upward under the elastic action of the spring 208, generating a small high-frequency vibration on the collection bag 5, shaking off the powder. The collection chamber 701 collects the two particle sizes of powder collected by the first separation cylinder 1 and the second separation cylinder 2. The second motor 801 drives the auger 8 to rotate. The auger 8 with opposite spiral directions at both ends generates opposite conveying forces, conveying the powder out from the discharge port 702.

[0030] Through the above steps, the first separating cylinder 1 is used for cyclone separation to separate materials with larger particle sizes. The materials with smaller particle sizes enter the second separating cylinder 2 with the air and are then filtered and collected by the collection bag 5. The vibration component applies small-amplitude high-frequency vibration to the collection bag 5 to shake off the materials attached to the collection bag 5 for collection. The discharge seat 7 collects materials of two different particle sizes and conveys them out of the device in two directions through the auger 8.
