Description

Technical Field

[0001] This invention specifically relates to a waste recycling device for dust control in refractory material production, belonging to the technical field of refractory material processing equipment. Background Technology

[0002] Refractory materials are a class of inorganic non-metallic materials with a refractoriness of not less than 1580℃. Refractoriness refers to the Celsius temperature at which a conical specimen of refractory material, under no load, resists high temperatures without softening or melting. During the production and processing of refractory materials, raw materials are crushed, ground, sieved, and mixed. The mixture is then fed into a mold cavity to be made into finished products. Dust is easily generated at various points during the refractory material manufacturing process, causing environmental pollution and reducing the yield of refractory materials. Furthermore, dust can easily lead to the loss of product components, resulting in errors in the original formula and affecting the thermal shock resistance, high-temperature strength, erosion resistance, and corrosion resistance of the refractory products. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a waste recycling device for dust control in refractory material production. This device collects raw material dust on-site, completes dust recycling, and then delivers the raw materials to their processing point, achieving on-site dust recycling and on-site application.

[0005] The main controller for overall machine control.

[0006] The tunnel-type dust control equipment includes a frame body installed around the feeding port of a feeding device, with a vacuum feeder installed on the top of the feeding device; the bottom of the frame body is hollow, and elongated covers are installed on the front, back, and top surfaces of the frame body; the elongated covers have grid grooves inside the frame body; a dust extraction pipe is installed on the side of the elongated covers away from the grid grooves; the dust extraction pipe is connected to a main pipe that is closed at one end; the main pipe is connected to the feeding port of the vacuum feeder via a negative pressure fan; and a photoelectric switch is installed inside the frame body.

[0007] The fixed-point dust control equipment includes a dust collector and a dust discharge device; the dust collector and dust discharge device includes a chamber base; a dust collection hood is provided on one side of the top of the chamber base, and a vacuum negative pressure chamber is provided on the other side of the top of the chamber base; a negative pressure extraction device is provided on the vacuum negative pressure chamber; the inner side of the vacuum negative pressure chamber is filled with filter material; a filter screen is provided between the chamber base and the vacuum negative pressure chamber; a negative pressure pipe is provided at the top of the vacuum negative pressure chamber; an air inlet grille is provided on the side of the chamber base near the dust collection hood; a cylindrical silo is provided at the bottom of the chamber base; a feed neck is provided at the top of the cylindrical silo; the cylindrical silo... A return material inclined nozzle is provided at the bottom; an X-shaped valve plate is provided on the inner side of the cylindrical silo; the valve plate is fitted against the inner wall of the cylindrical silo, and a hydraulic motor is fixed to the outside of the cylindrical silo; a blow pipe is provided on the upper inner side of the return material inclined nozzle; one end of the blow pipe is closed, and the other end is connected to the blower; a blow nozzle is provided at the bottom of the blow pipe; a support is integrally formed on the bottom of the cavity seat away from the return material inclined nozzle; the support is fixed to the periphery of the open hopper, belt silo, and / or chute discharge hopper; the return material inclined nozzle is connected to the inner side of the open hopper, belt silo, and / or chute discharge hopper.

[0008] The mobile dust control equipment includes a dust collector and a material feeder, the support of which is fixed on the slider of the slide block, and a hydraulic cylinder is provided between the support and the slide block; the slide block is fixed to the periphery of the mold.

[0009] The fixed-point dust control equipment is equipped with a cloth bag sleeve at the return inlet.

[0010] The return feed nozzle of the mobile dust control device is connected to the side of the feed cylinder; an exhaust hood is provided at the top of the feed cylinder; and a feed outlet is provided at the bottom of the feed cylinder.

[0011] Furthermore, the cavity seat is a square or C-shaped structure; the return material oblique nozzle is located on the side of the cavity seat near the vacuum negative pressure chamber.

[0012] Furthermore, the air intake grille has an outer wide and inner narrow structure, which collects dust and prevents it from overflowing.

[0013] Furthermore, the vacuum feeder includes a flange discharge port located at the top of the feed cylinder; the vacuum cylinder is fixed to the flange discharge port via a flange; a filter screen is provided on the top inner side of the vacuum cylinder; an exhaust pipe is provided above the filter screen on the vacuum cylinder; and a feed pipe is provided below the filter screen on the vacuum cylinder. The gas-powder mixture enters the vacuum cylinder and is filtered through the filter screen. The gas is exhausted through the exhaust pipe, and the powder falls into the feed equipment from the flange discharge port.

[0014] Furthermore, the working process of the tunnel-type dust control equipment is as follows:

[0015] When the forklift scoops up bauxite, coke, and other ingredients from the raw material workshop and feeds them into the inlet of the feeding equipment, the feeding equipment conveys them to the crushing and screening equipment via a belt. When the forklift scoops material from the stockpile and moves towards the inlet of the feeding equipment, it triggers the photoelectric switch, which turns on the negative pressure fan. The negative pressure fan generates negative pressure, which, through the dust extraction pipe, creates negative pressure on the long hood, thereby sucking the dust generated by the falling raw materials from the grid channel into the long hood and sending it into the vacuum feeder. The vacuum feeder completes the exhaust and guides the dust into the feeding equipment, which then sends it to the processing point.

[0016] Furthermore, the working process of the fixed-point dust control equipment is as follows:

[0017] When the raw materials are crushed and enter the hopper of the screening equipment, or after screening they enter the hopper of the mixing equipment, or after mixing they enter the hopper of the metering equipment, the dust collector outside the hopper performs in-situ dust collection and material discharge. When the upper-level processing equipment sends a material discharge signal, the negative pressure extraction equipment is activated, providing negative pressure to the chamber seat through the vacuum negative pressure chamber. The negative pressure collects the dust inside the chamber seat through the dust collection hood and air inlet grille. The negative pressure separates the air and dust through the filter material and filter screen plate, and the dust falls into the cylindrical silo of the chamber seat. The negative pressure extraction equipment and the blower alternate. When the dust falls onto the valve plate and accumulates for a certain period of time, the hydraulic motor is activated, realizing the valve plate rotating 180°, thereby dividing the cylindrical silo into upper and lower chambers. The upper chamber completes the dust collection, and the blower guides the dust collected in the lower chamber to the return material incline through the blower pipe. Low-pressure blowing guides the dust into the bag sleeve, completing the dust return and preventing its overflow.

[0018] Furthermore, the working process of the mobile dust suppression equipment is as follows:

[0019] The dust extraction method of the mobile dust suppression equipment is the same as that of the fixed-point dust suppression equipment. The dust extraction of the mobile dust suppression equipment is continuous. When the material is dropped, the hydraulic cylinder pushes the slider so that the dropping port is directly above the mold cavity, so that the raw material is collected in place and sent into the mold cavity in place. The timing of the hydraulic cylinder action is: the signal of the stamping equipment falling back.

[0020] Compared with the prior art, the dust-preventing waste recycling equipment for refractory material production of the present invention is installed at the open feeding point of each processing equipment. It can collect raw material dust on-site and send the raw materials to their processing points. The composition of the collected material is consistent with the composition of the raw materials to be sent to the processing points, realizing on-site dust recycling and on-site return for application. In particular, for the end processing equipment (refractory brick stamping end), the dust recycling can ensure that the refractory brick components are not lost, thus preventing the problem of insufficient composition, and at the same time, it can purify each processing point.
