Description

Technical Field

[0001] This invention relates to the field of calcium silicate board production technology, and particularly to a flow mill based on calcium silicate board production. Background Technology

[0002] Calcium silicate board is a board made by using loose short fibers such as inorganic mineral fibers or cellulose fibers as reinforcing materials and siliceous and calcareous materials as the main binding materials. It is made by pulping, molding, and accelerating the curing reaction in high temperature and high pressure saturated steam to form calcium silicate gel.

[0003] Currently, the flow machines used for producing calcium silicate boards cannot achieve quantitative flow of the slurry. They also make it inconvenient for workers to adjust the weight of the slurry, which reduces the production precision of calcium silicate boards. Furthermore, the lack of anti-settling structures makes the slurry prone to sedimentation. Summary of the Invention

[0004] In view of this, the present invention provides a headstock machine for calcium silicate board production, which has a headstock storage component, a sealing component, a metering headstock component, and an anti-sedimentation component.

The headstock inside the metering headstock tube A and metering headstock tube B flows out automatically, ensuring that the headstock weight is always the same, thus improving the production accuracy of calcium silicate boards. When the operator pulls one of the pull handles and then releases it, the movable connecting plate moves back and forth for a period of time under the action of four return springs B, which makes the headstock inside the headstock storage tank more evenly agitated.

Beneficial effects

[0015] 1. In this invention, the quantitative slurry tube B is slidably installed on the outer wall of the quantitative slurry tube A, and two fixing screws are threadedly connected to the quantitative slurry tube B, with the inner ends of the two fixing screws contacting the quantitative slurry tube A. This allows the operator to adjust the height of the quantitative slurry tube B appropriately using the two fixing screws, facilitating control of the slurry weight.

This allows for the use of quantitative slurry pipes B of different heights, ensuring a good sealing effect. Furthermore, since the slurry discharge pipe B is fixedly installed at the bottom of the sealing plate, when the two electric telescopic rods are working, the quantitative slurry pipe B and the slurry discharge pipe B are concentrically positioned, allowing the slurry inside the quantitative slurry pipes A and B to flow out automatically, ensuring that the slurry weight is always the same and improving the production accuracy of calcium silicate boards.

[0017] 3. In this invention, the anti-settling shaft is fixedly installed at the bottom of the servo motor, and four anti-settling brackets are fixedly installed on the outer wall of the anti-settling shaft.

[0022] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

The screws 306 are threaded onto the metering slurry pipe B305, and the inner ends of the two fixing screws 306 are in contact with the metering slurry pipe A304. Their specific function is as follows: Because the metering slurry pipe B305 is slidably installed on the outer wall of the metering slurry pipe A304, and the two fixing screws 306 are threaded onto the metering slurry pipe B305, with the inner ends of the two fixing screws 306 in contact with the metering slurry pipe A304, it is convenient for workers to adjust the height of the metering slurry pipe B305 appropriately using the two fixing screws 306, making it easier for workers to control the slurry weight. Furthermore, because the sealing baffle B303 is fixedly installed on the right side of the two electric telescopic rods 302, and the top of the sealing baffle B303 is in contact with the sealing baffle A104, when the two electric telescopic rods 302 are working, the sealing baffle B303 moves to the right, sealing the slurry outlet pipe A103.

[0025] The sealing assembly 2 includes: a mounting plate 201 and a stabilizing guide shaft 202; two mounting plates 201 are provided, and the two mounting plates 201 are fixedly installed at the bottom of the slurry storage tank 102; two stabilizing guide shafts 202 are provided, and the two stabilizing guide shafts 202 are fixedly installed at the bottom of the two mounting plates 201; the sealing assembly 2 also includes: a sealing plate 203 and a slurry discharge pipe B204; the sealing plate 203 is slidably installed on the outer wall of the two stabilizing guide shafts 202; the slurry discharge pipe B204 is fixedly installed at the bottom of the sealing plate 203; the sealing assembly 2 also includes: a limiting ring 205 and a return spring A206; two limiting rings 205 are provided, and the two limiting rings 205 are fixedly installed at the bottom of the two stabilizing guide shafts 202, and the bottom of the two limiting rings 205 is flush with the bottom of the two stabilizing guide shafts 202; the return spring A206 is provided... There are two return springs A206 installed outside the two stabilizing guide shafts 202, and the two return springs A206 are located between the sealing plate 203 and the two limiting rings 205. Their specific function is as follows: because the bottom of the quantitative slurry pipe B305 is in contact with the sealing plate 203, and the two return springs A206 are located between the sealing plate 203 and the two limiting rings 205, the sealing plate 203 can move up and down, which can accommodate quantitative slurry pipes B305 of different heights, ensuring the sealing effect. Since the slurry discharge pipe B204 is fixedly installed at the bottom of the sealing plate 203, when the two electric telescopic rods 302 work, the quantitative slurry pipe B305 and the slurry discharge pipe B204 are concentrically set, so that the slurry inside the quantitative slurry pipes A304 and B305 automatically flows out, ensuring that the slurry weight is always the same and improving the production accuracy of calcium silicate board.

The four return springs B407 are fixedly installed on the left and right sides of the movable connecting plate 401, and their outer ends are fixedly connected to the slurry storage tank 102. Their specific functions are as follows: Since the anti-settling shaft 403 is fixedly installed on the bottom of the servo motor 402, and the four anti-settling brackets 404 are fixedly installed on the outer wall of the anti-settling shaft 403, when the servo motor 402 is working, the four anti-settling brackets 404 rotate, which agitates the slurry inside the slurry storage tank 102 and prevents the slurry from settling. Since the movable connecting plate 401 is slidably installed on the slurry storage tank 102, and the four return springs B407 are fixedly installed on the left and right sides of the movable connecting plate 401, and their outer ends are fixedly connected to the slurry storage tank 102, when the operator pulls one of the pull handles 406 and then releases it, the movable connecting plate 401 moves back and forth left and right for a period of time under the action of the four return springs B407, so that the slurry inside the slurry storage tank 102 is agitated more evenly.

[0027] The specific usage and function of this embodiment: In this invention, firstly, the operator installs the two support frames 101 in the appropriate position using bolts.

The setting of the sealing baffle A104 prevents the slurry inside the slurry storage tank 102 from flowing out. The sealing plate 203 can move up and down to accommodate quantitative slurry pipes B305 of different heights, ensuring the sealing effect. When the two electric telescopic rods 302 are working... 2. During operation, the quantitative slurry pipe B305 and the slurry discharge pipe B204 are concentrically set, so that the slurry inside the quantitative slurry pipes A304 and B305 flows out automatically, ensuring that the slurry weight is always the same and improving the production accuracy of calcium silicate boards. When the servo motor 402 is working, the four anti-sedimentation racks 404 rotate, which agitates the slurry inside the slurry storage tank 102 and prevents the slurry from settling.
