Abstract

Technical Field
[0001] This utility model belongs to the field of ash removal hoppers, and in particular relates to an ash removal hopper for glass kilns. Background Technology
[0002] To meet environmental protection requirements, industrial flue gas needs to be desulfurized and denitrified. During the treatment process, quicklime powder needs to be added to the flue gas. The quicklime powder reacts with acidic pollutants in the flue gas to produce waste ash (mainly including quicklime, hydrated lime, calcium carbonate, calcium sulfate and other substances).
[0003] To ensure that the flue gas meets emission standards, a dust collector is needed to remove dust from the flue gas. For ease of understanding by those skilled in the art, the dust collector is described as a ceramic tube dust collector. The ceramic tube dust collector includes a filter cartridge, a pulse jet air manifold, and a dust collection hopper. The filter cartridge is used to intercept waste ash in the flue gas, and the pulse jet air manifold is used to spray air into the filter cartridge so that the waste ash adhering to the filter cartridge falls into the dust collection hopper.
[0004] For glass kilns, the flue gas contains not only the aforementioned waste ash, but also needle-like glass fibers. The filter cartridge is used to intercept the glass fibers, and the pulse jet air manifold can also cause the glass fibers to fall into the ash removal hopper.
[0005] In the original technology, the ash removal hopper used in the glass furnace consisted of a cylindrical box and a frustum-shaped funnel, through which waste ash and glass fibers could flow out from the bottom of the frustum-shaped funnel under the guidance of the funnel.
[0006] In the aforementioned technologies, when multiple ash removal hoppers are centrally located, there are significant gaps between the cylindrical housings of adjacent ash removal hoppers. While ensuring that the volume of all ash removal hoppers meets production line design standards, the number of ash removal hoppers is large, and the total floor space occupied by all ash removal hoppers is substantial.
[0007] To solve the above problems, such as Figure 1 and Figure 2 As shown, the applicant attempted to replace the ash removal hopper 1 with a different specification. The ash removal hopper 1 includes a square box 2 and a frustum-shaped funnel 3. When multiple ash removal hoppers 1 are set up together, no gap is required between the square boxes 2 of adjacent ash removal hoppers 1. While ensuring that the volume of all ash removal hoppers 1 meets the production line design standards, and with the height of the ash removal hoppers 1 remaining unchanged, the number of ash removal hoppers 1 is reduced, and the footprint of all ash removal hoppers 1 is smaller.
[0008] In actual production, because the included angle between the two adjacent sides of the truncated quadrangular funnel 3 is an acute angle and the glass fiber has a needle-like structure, the glass fiber gets stuck at the included angle between the two adjacent sides. As a result, the waste ash and glass fiber adhere to the included angle between the two adjacent sides of the truncated quadrangular funnel 3 and cannot be discharged in time. This leads to ash blockage in the ash removal hopper, which cannot discharge the waste ash and glass fiber normally.
[0009] To solve the above problems, the applicant attempted to weld a 100mm wide flat iron at the junction of two adjacent sides of the truncated quadrangular funnel 3, thereby changing one acute angle at the junction of the two adjacent sides into two obtuse angles. The two obtuse angles are the included angles between the flat iron and the two adjacent sides, thereby improving the ash removal hopper blockage.
[0010] During continued production, the applicant discovered that welding flat iron could only improve the situation of ash clogging in the ash removal hopper, but could not fundamentally solve the problem of ash clogging in the ash removal hopper. After long-term use, the ash removal hopper would still experience ash clogging, affecting safe production. Utility Model Content
[0011] The purpose of this utility model is to provide an ash removal hopper for glass kilns, which solves the technical problem of ash blockage in ash removal hoppers while ensuring that the ash removal hopper occupies a small area when centrally arranged.
[0012] To achieve the above objectives, the technical solution for the ash removal hopper for glass kilns provided by this utility model is as follows:
[0013] A dust removal hopper for a glass kiln includes a square box, a square-shaped tube, and a frustum-shaped funnel. The square box, the square-shaped tube, and the frustum-shaped funnel are connected in sequence from top to bottom. The projection of the circular lower end of the square-shaped tube in the horizontal plane is located within the projection of the square upper end of the square-shaped tube in the horizontal plane.
[0014] The beneficial effects of the ash removal hopper for glass kilns provided by this utility model are as follows: This utility model is an improved invention. The core innovation of this utility model lies in the fact that it simultaneously adopts a square box and a frustum-shaped funnel, and uses a square-top-round-bottom tube to achieve a transition, thus possessing the advantages of both square box and frustum-shaped funnel. The square box ensures that the ash removal hopper occupies a small area when centrally arranged, and the frustum-shaped funnel avoids ash blockage; at the same time, the inner wall of the square-top-round-bottom tube has no dead corners, so it can prevent glass fiber from getting stuck in the square-top-round-bottom tube, thereby ensuring that the ash removal hopper is completely free from ash blockage.

[0021] To address the problems in the background technology, the core inventive concept of this utility model is to combine a square box and a frustum-shaped funnel using a square tube, thereby enabling the ash removal hopper to simultaneously possess the advantages of both a square box and a frustum-shaped funnel.
[0022] The present invention will be further described in detail below with reference to an embodiment of an ash removal hopper for a glass kiln.
[0023] like Figure 3 As shown, the ash removal hopper for a glass kiln includes a square box 2, a square-bottomed circular tube 4, and a frustum-shaped funnel 5, which are connected sequentially from top to bottom. The projection of the circular lower end of the square-bottomed circular tube 4 in the horizontal plane lies within the projection of the square upper end of the square-bottomed circular tube 4 in the horizontal plane, thus avoiding interference between the square-bottomed circular tube 4 and the frustum-shaped funnel 5 of adjacent ash removal hoppers when multiple square boxes 2 are arranged close together. The square-bottomed circular tube 4 is mainly made of carbon steel and / or stainless steel, preferably stainless steel. The square box 2 and the frustum-shaped funnel 5 are made of the same material as the box and funnel in the prior art, preferably stainless steel.
[0024] Preferably, the lower end of the square box 2 is welded to the upper end of the square tube 4, and the lower end of the square tube 4 is welded to the upper end of the frustum-shaped funnel 5, resulting in a simple structure.
[0025] Alternatively, square flanges and round flanges can be installed at the upper and lower ends of the square-to-ground circular pipe 4, respectively, and a corresponding square flange can be installed at the lower end of the square box 2, and a corresponding round flange can be installed at the upper end of the frustum-shaped funnel 5, so that the square-to-ground circular pipe 4 is flangedly connected to both the square box 2 and the frustum-shaped funnel 5. In this case, due to the presence of the square flanges, there will be gaps between the square boxes 2 of adjacent ash removal hoppers.
[0026] Among them, the Tianfangdiyuan pipe 4 is an existing technology and can be purchased as a whole. For specific customization, you can contact companies such as Hebei Huikuo Pipeline Equipment Manufacturing Co., Ltd. or Cangzhou Ruiyi Pipeline Equipment Co., Ltd.
[0027] To facilitate understanding of this utility model by those skilled in the art, the following provides a detailed description of the Tianfangdiyuan tube 4.
[0028] The "square-earth-round tube 4" refers to a tube with a square inlet and a round outlet, formed by combining triangular and fan-shaped arc plates. It can also be cast in one piece, resulting in a relatively smooth inner wall surface and preventing fiberglass from getting stuck. In contrast, the "round-earth-square tube" refers to a tube with a round inlet and a square outlet.
[0029] Tianfangdiyuan pipe 4 is an irregularly shaped pipe fitting used to connect square pipes (replaced by square box 2 in this utility model) and round pipes (replaced by frustum-shaped funnel 5 in this utility model). It belongs to the pipe fitting category in hardware parts. Its main function is to realize the transition connection of pipes with different cross-sectional shapes in ventilation, air conditioning, chemical, power plant and other systems.
[0030] This utility model employs both a square box 2 and a frustum-shaped funnel 5, and uses a square-to-round tube 4 for transition, thus combining the advantages of both the square box 2 and the frustum-shaped funnel 5. The square box 2 ensures a small footprint when the ash removal hoppers are centrally arranged, while the frustum-shaped funnel 5 prevents ash blockage. At the same time, the inner wall of the square-to-round tube 4 has no dead corners, so it can prevent glass fiber from getting stuck inside the tube, thus ensuring that the ash removal hopper is completely free from ash blockage.
[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some technical features, or organically combine different specific implementation methods to create the specific implementation methods shown in the accompanying drawings. Of course, those skilled in the art can also create other specific implementation methods not shown in the accompanying drawings. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
