Description

Technical Field

[0001] The invention belongs to the technical field of calcium powder conveying, and in particular relates to a powder conveying device and a conveying method thereof for calcium powder production. Background Art

[0002] Calcium powder usually refers to the powder form of limestone (or its derivatives) after processing. For the complete processing of calcium powder, conveying equipment is usually required for transportation, and the intermediate product is transferred and processed. Usually a screw conveyor is used for transportation.

[0003] In the prior art, the powder conveying device used for calcium powder production usually feeds calcium powder into the conveying device for continuous conveying during use. During the conveying process, the calcium powder has a fine texture and a small particle size. During the conveying process, it is easy to adhere to the inner wall of the conveying tube, resulting in poor conveying or even blockage. However, it is difficult to clean and clear the calcium powder inside the conveying tube, and usually it is necessary to stop the machine and use external knocking. In fact, the wall thickness of the conveying tube is high, the external vibration effect is not good, the calcium powder separation effect is poor, and the conveying effect is not good.

[0004] In addition, after the transportation is completed, the residual calcium powder inside the conveying cylinder cannot be effectively and timely handled. On the one hand, it affects the total amount of calcium powder collected after transportation. On the other hand, the residual calcium powder oxidizes and regains moisture in the conveying cylinder and corrodes the inner wall of the conveying cylinder. In the current cleaning operation, when pressurized air is introduced, the spiral blades in the conveying cylinder divide the interior of the conveying cylinder into multiple groups of incompletely connected intervals. Each interval is difficult to receive wind sweeping, and effective internal cleaning still cannot be achieved. The cleaning is difficult and the effect is poor. Summary of the invention

[0016] A conveying method of a powder conveying device for calcium powder production, comprising the following operating steps:

[0017] Step 1: When in use, put the calcium powder with conveyor into the feeding funnel, and the calcium powder enters the elastic thin tube through the feeding curved hole, start the spiral conveying part, the spiral blade rotates in the elastic thin tube, and performs basic conveying;

[0018] Step 2: Start the rotating assembly. The gear 1 of the rotating assembly drives the meshing gear 2 to rotate, so that the extruded tube rotates. As the extruded tube rotates, the multiple groups of raised parts inside are driven to rotate. When the raised parts rotate to the vibration assembly, the vibration assembly is pushed to compress and hit the elastic thin tube. As the extruded tube continues to rotate, the vibration assembly is intermittently pushed to move and complete continuous vibration. The calcium powder attached to the inner wall of the elastic thin tube is detached and quickly transported out through the spiral blades.

[0019] Step 3: As the calcium powder is transported to the outlet end of the conveying cylinder and falls into the screening component, and as the spiral conveying part drives the screening component to rotate, the fine calcium powder intermittently falls into the discharging part through the rotating screening component and falls downward, and the large-particle calcium powder after screening is retained in the screening component, and as the screening component rotates, its inner wall continuously rubs against the fixed cleaning rod to complete the self-clearing;

[0020] Step 4: After the conveying is completed, when cleaning the inside of the conveying tube, directly insert the external air pipe into the feed funnel, input pressurized air through the feed curved hole, and pass it into the elastic thin tube, start the electromagnet in the support tube, so that the electromagnet is energized to generate magnetism, and adsorbs toward the metal rod on the outer side of the elastic thin tube, the metal rod moves outward and is adsorbed and fixed in the electromagnet, and as the metal rod moves and stretches, the elastic thin tube is elastically deformed and bulges outward, and a non-contact space is generated between the spiral blades and the elastic thin tube, accompanied by pressurized air blowing, the calcium powder remaining in the inner wall of the elastic thin tube is blown out directly toward the outer end of the conveying tube along the connecting gap of the elastic deformation, and the cleaning is quickly completed.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The present invention utilizes a rotating component, an extrusion tube and a protrusion, and under rotation control, the extrusion tube drives the protrusion to intermittently squeeze and push the vibration component, thereby realizing the elastic action of the vibration component, and continuously impacting and vibrating the elastic thin tube during the rotation process. The elastic effect of the elastic thin tube is utilized to realize high-frequency vibration during the conveying process, so that the calcium powder attached and accumulated on the inner wall of the elastic thin tube is peeled off, and then quickly spirally conveyed out. For the conveying of calcium powder, the actual conveying effect is greatly improved, and the blockage and poor conveying caused by the inner wall adhesion are avoided, and the use effect is good.

[0023] 2. The present invention utilizes a screening component sleeved and installed on the right end of the conveying cylinder to synchronously drive the screening component to rotate during the rotating conveying process, and cooperates with the screening holes partially opened in the screening component to ensure that screening is only achieved when the screening hole is close to the bottom, and intermittent screening of calcium powder is achieved. At the same time, the continuously rotating screening component is utilized to provide screening disturbance to avoid rapid clogging of the screening hole and affect the screening effect. In addition, in cooperation with the fixed cleaning rod, the inner wall of the screening hole is automatically cleaned during the rotation process. During the rotation process, the screening hole is automatically cleared, the operation is simple, and the self-clearing effect is good.

[0024] 3. The present invention utilizes the elasticity and thin plate characteristics of the elastic thin tube again, cooperates with the metal rod embedded on the outer side, and the electromagnet in the support tube, and uses strong magnetic attraction to fix the metal rod when the electromagnet is energized. The elastic thin tube is stretched outward due to the movement of the metal rod through the adsorption and fixing effect, thereby forming a certain non-contact space between the elastic thin tube and the spiral blades, and forming a through gap at the left and right ends of the elastic thin tube. The residual calcium powder is directly blown out through the through gap by the effect of the input pressure air, completing rapid cleaning, avoiding the spiral blades from forming multiple isolation spaces, and improving the cleaning effect of the residual calcium powder inside the conveying tube. The operation is simple and the use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] Step 2: Start the rotating assembly 10, and the gear 1 102 of the rotating assembly 10 drives the meshing gear 2 103 to rotate, so that the extrusion tube 9 rotates. As the extrusion tube 9 rotates, the multiple groups of protrusions 11 inside are driven to rotate. When the protrusions 11 rotate to the vibration assembly 8, the vibration assembly 8 is pushed to compress and hit the elastic thin tube 6.

10. A conveying method of a powder conveying device for calcium powder production according to claim 9, characterized in that: The steps include: The first step: when in use, the calcium powder to be conveyed is put into the feeding funnel (4), and the calcium powder enters the elastic thin tube (6) through the feeding curved hole (5), the spiral conveying part (3) is started, and the spiral blade (33) rotates in the elastic thin tube (6) to perform basic conveying; Step 2: Start the rotating assembly (10), and the gear 1 (102) of the rotating assembly (10) drives the meshing gear 2 (103) to rotate, so that the extrusion tube (9) rotates. As the extrusion tube (9) rotates, the multiple groups of raised parts (11) inside are driven to rotate. When the raised parts (11) rotate to the vibration assembly (8), the vibration assembly (8) is pushed to compress and hit the elastic thin tube (6). As the extrusion tube (9) continues to rotate, the vibration assembly (8) is intermittently pushed to move and complete continuous vibration. The calcium powder attached to the inner wall of the elastic thin tube (6) is detached and quickly transported out through the spiral blades (33); Step 3: As the calcium powder is transported to the outlet end of the conveying cylinder (1) and falls into the screening assembly (13), and as the spiral conveying part (3) drives the screening assembly (13) to rotate, the fine calcium powder intermittently falls into the discharging part (12) through the rotating screening assembly (13) and falls downward, and the large-particle calcium powder after screening is retained in the screening assembly (13), and as the screening assembly (13) rotates, its inner wall continuously rubs against the fixed cleaning rod (14), completing self-clearing; Step 4: After the conveying is completed, when cleaning the inside of the conveying tube (1), the external air pipe is directly inserted into the feeding funnel (4), and the pressurized air is input through the feeding curved hole (5) and passed into the elastic thin tube (6). The electromagnet (73) in the support tube (7) is started, so that the electromagnet (73) is energized to generate magnetism and adsorbs the metal rod (63) on the outer side of the elastic thin tube (6). The metal rod (63) moves outward and is adsorbed and fixed in the electromagnet (73). As the metal rod (63) moves and stretches, the elastic thin tube (6) is elastically deformed and bulges outward, and a non-contact space is generated between the spiral blade (33) and the elastic thin tube (6). Accompanied by the pressurized air blowing, the calcium powder remaining in the inner wall of the elastic thin tube (6) is blown out directly toward the outer end of the conveying tube (1) along the elastic deformation connecting gap, and the cleaning is quickly completed.
