Description

Technical Field

[0001] This utility model relates to the field of vitrified microsphere production technology, specifically to a vitrified microsphere twin-cell electric furnace material collection and feeding device. Background Technology

[0002] Vitrified microspheres are lightweight, hollow, closed spheres formed by the instantaneous expansion of inorganic glassy materials at high temperatures. They are characterized by low density, low thermal conductivity, high strength, good chemical stability, and excellent fluidity, and are widely used in building insulation mortar, fireproof coatings, oil well cementing, deep-sea buoyancy materials, aerospace composite materials, and other fields.

[0003] Traditional material collection devices typically use simple Y-shaped or T-shaped tee pipes to merge two material streams. This structure easily causes uneven material flow velocity and turbulent impact at the merging point, resulting in insufficient mixing of the two materials and a "segregation" phenomenon. This means that during subsequent conveying, the material's composition, particle size, or temperature distribution is uneven, affecting the quality stability of the final product.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned problems and provide a material collection and feeding device for a double electric furnace with vitrified microspheres.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a material collection and discharging device for a double-unit electric furnace of vitrified microspheres, comprising: A furnace air pressure balance box fixedly connected to a ring frame; Among them, a pair of discharge pipes are connected to the furnace air pressure balance box, and an observation telescopic sleeve is fixedly connected to the end of the discharge pipe away from the furnace air pressure balance box. A dropping hopper is connected to the observation telescopic sleeve. The discharge pipe is located inside the annular frame and is connected to the furnace air pressure balance box.

[0007] Preferably, multiple support legs are symmetrically fixedly connected to the outer wall of the ring frame.

[0008] Preferably, the discharge tube is bent, with a bending angle greater than 90° and less than 180°.

[0009] Preferably, a number of hanging ears are fixedly connected around the outer wall of the hopper, and a pair of fixed frames with a number of pulleys are also fixedly connected to the outer wall of the hopper.

[0010] Preferably, it further includes: a pair of support frames, on which two scaffolds and guide frames are fixedly connected.

[0011] The advantages of this utility model compared with the prior art are as follows: This invention provides a spacious buffer and premixing space for the two streams of materials from a twin-furnace by setting up a funnel-shaped air pressure balancing box that is wider at the top and narrower at the bottom. After the materials enter the air pressure balancing box, the flow rate decreases and the impact force is buffered, allowing for thorough and uniform mixing within the box. This effectively avoids the segregation problem that occurs when materials converge in traditional three-way pipes, ensuring that the composition and state of the materials entering the next process are uniform and stable, thereby significantly improving the quality of the final product.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: like Figures 1 to 4 As shown, this utility model provides a material collection and feeding device for a double electric furnace of vitrified microspheres, including an annular frame 2.

[0020] The annular frame 2 is circular in shape, consisting of an annular positioning frame and a baffle fixedly connected to the rear end of the positioning frame. Multiple support legs 7 are then fixedly connected to the outer wall of the positioning frame in the annular frame 2. In this embodiment, there are four support legs 7, arranged diagonally. Both the positioning frame and the baffle in the annular frame 2 are made of 304 stainless steel.

[0021] A furnace pressure balancing box 1 is fixedly connected to the rear end of the baffle in the annular frame 2. Specifically, the furnace pressure balancing box 1 is funnel-shaped, wider at the top and narrower at the bottom. Discharge pipes 3 are fixedly connected to both sides of the top of the furnace pressure balancing box 1, and the bottom end of the discharge pipes 3 connects to the inner cavity of the furnace pressure balancing box 1. The discharge pipes 3 are made of 310s stainless steel with a thickness of 10mm.

[0022] Among them, the feeding pipe 3 is bent and placed obliquely backward, and the bending angle of the feeding pipe 3 is greater than 90° and less than 180°.

[0023] Meanwhile, multiple connecting brackets are fixedly connected to the adjacent sides of the two discharge pipes 3. In this embodiment, there are two connecting brackets. The two connecting brackets ensure that the two discharge pipes 3 remain relatively stable during operation, reducing vibration and relative rotation of the discharge pipes 3.

[0024] In addition, the discharge pipe 6 passes through the baffle of the annular frame 2 and the furnace air pressure balance box 1 from front to back, and extends into the inner cavity of the furnace air pressure balance box 1, and the discharge pipe 6 is fixedly connected to the furnace air pressure balance box 1.

[0025] The end of the discharge pipe 3 furthest from the furnace pressure balance box 1 is fixedly connected to an observation telescopic sleeve 4 by bolts. The observation telescopic sleeve 4 and the discharge pipe 3 are coaxially connected. The end of the observation telescopic sleeve 4 furthest from the discharge pipe 3 is fixedly connected to a dropping hopper 5 by bolts. Finally, the dropping hopper 5 is connected to an external collection box. The dropping hopper 5 is made of 310s stainless steel.

[0026] In this embodiment, when the vitrified microsphere material in the two collection boxes is fed into the corresponding discharge hopper 5, it then enters the discharge pipe 3 through the observation telescopic sleeve 4. During this process, the material flow status can be observed directly and the length can be finely adjusted.

[0027] After being transported along their respective discharge pipes 3, the two material streams converge and mix thoroughly within the inner cavity of the furnace air pressure balance box 1. Under the influence of gravity and the overall layout of the equipment, the mixed material flows downwards and is stably discharged from the furnace air pressure balance box 1 through the discharge pipe 6, and is then transported to subsequent process equipment for further processing.

[0028] Example 2: During the processing of vitrified microspheres, high temperatures can cause dust to clump together and adhere to the inner wall of the collection box. If this clump is not cleaned in time, it will affect the subsequent processing of the vitrified microspheres. To facilitate the timely removal of the slag, Example 2 is proposed.

[0029] The vitrified microsphere twin-cell electric furnace material collection and discharging device also includes a pair of support frames 8, which are I-shaped and symmetrically arranged around the annular frame 2. A pair of scaffolds 9 are fixedly connected to the top of both support frames 8. Meanwhile, guide frames 10 are fixedly connected to the upper parts of the front and rear walls of the support frames 8, and guide grooves are provided at the top of the guide frames 10.

[0030] Meanwhile, a fixed frame 502 is fixedly connected to both side walls of each hopper 5. A pulley 503 is fixedly connected to the front and rear of the bottom end of the fixed frame 502. When the hopper 5 descends, the pulley 503 can fall into the guide groove at the top of the guide frame 10.

[0031] In addition, to facilitate loading and unloading of the hopper 5, several lugs 501 are fixedly connected around the outer wall of the hopper 5. In this embodiment, there are four lugs 501. At the same time, a lifting chain is installed on the lugs 501, and the other end of the lifting chain is connected to the external collection box. When the equipment is running, the lifting chain keeps the hopper 5 in close contact with the collection box.

[0032] When it is necessary to clean the slag in the collection box, first stop the operation of the equipment and allow the entire collection and discharge device to cool down. Then, remove the bolts between the observation telescopic sleeve 4 and the discharge hopper 5, and let the observation telescopic sleeve 4 fall naturally. Then loosen the lifting chain on the hanging lug 501. At this time, since the position of the discharge hopper 5 is no longer restricted, the observation telescopic sleeve 4 will fall naturally as the lifting chain is loosened until the pulley 503 on the fixed frame 502 falls into the guide groove on the guide frame 10.

[0033] Then, slide the hopper 5 to one side along the guide groove on the guide frame 10. As the equipment continues to cool, the slag inside the collection box will naturally fall off along the inner wall of the collection box and be discharged to the outside from the outlet of the collection box. After cleaning, push the hopper 5 back under the collection box, tighten it with the lifting chain, and re-pick it up. Align the hopper 5 with the outlet of the collection box again. Finally, observe the extension of the telescopic sleeve 4 and re-fix the hopper 5 to the telescopic sleeve 4 with bolts, which greatly saves the time of maintenance and slag discharge. This also effectively protects the extensibility of the stainless steel heating furnace tubes.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.

[0035] The detailed description of known functions and components is omitted in this disclosure. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of commercially available instruments.
