Description

Technical Field

[0001] This utility model relates to the field of graphite processing technology, specifically a spherical graphite gas emission filtration device. Background Technology

[0002] Spherical graphite is a graphite product of varying fineness and elliptical spherical shape, produced by using high-quality, high-carbon natural flake graphite as raw material and advanced processing technology to modify the graphite surface.

[0003] The spherical graphite processing process begins in the spherical graphite workshop, where dry graphite concentrate undergoes coarse crushing, trimming, and magnetic separation to form the initial product, spherical graphite. This initial product then enters the purification workshop where it is purified at high temperature to become spherical graphite (high purity).

[0004] However, when traditional spherical graphite undergoes high-temperature purification in the purification workshop, it generates a large amount of gas, such as carbon monoxide and carbon dioxide caused by incomplete combustion. If these gases are released to the outside, they will pollute the environment. Therefore, the treatment and filtration of gases after high-temperature purification of spherical graphite is extremely important. To address this issue, we provide a spherical graphite gas emission filtration device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a spherical graphite gas emission filtration device. This device can perform multiple filtrations on the gas generated after the spherical graphite is purified at high temperature. Through the dual treatment of the gas by physical and chemical methods, it ensures that the gas will not cause air pollution after emission.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a spherical graphite gas emission filtration device, comprising a housing, wherein a conversion mechanism is provided inside the housing, the conversion mechanism comprising a filter box fixed to the inner wall of the housing, and a first vent pipe connected to the filter box and penetrating the inner wall of the housing, wherein a filter assembly is provided inside the filter box.

[0007] Furthermore, the conversion mechanism also includes a conversion box fixedly connected to the bottom wall of the box body, and a second vent pipe connected to and passing through the filter box. A one-way vent valve is installed at the lower end of the second vent pipe. By setting up the conversion box, it is convenient to store the mixture of chemical agents and water resources, so that the carbon monoxide produced by the incomplete combustion of spherical graphite can be converted into carbon dioxide that does not pollute the air and emitted through the mixture.

[0008] Furthermore, the upper surface of the conversion box is fixedly connected to a gas-gathering frame, and the output end of the gas-gathering frame penetrates the inner top wall of the box. By setting the gas-gathering frame, it is convenient to guide and discharge the filtered and converted pollution-free gas, and the gas in the conversion box can also be quickly extracted and discharged by an external air extraction device.

[0009] Furthermore, the filtration assembly includes a filter screen and an activated carbon layer located inside the filter box, as well as a pull plate connected to the filter screen and activated carbon layer. By setting up the filtration assembly, it is possible to perform the initial filtration of harmful gases generated after the spherical graphite is purified at high temperature, and to filter and block larger particles in the harmful gases.

[0010] Furthermore, the inner wall of the conversion box is fixedly connected with an output pipe and an input pipe, and the outer ends of the output pipe and the input pipe pass through the conversion box and the box body in sequence and extend to the outside of the box body. By setting the output pipe, it is convenient to extract the solution in the conversion box, and the solution can be filled into the conversion box through the input pipe.

[0011] Furthermore, a door is hinged to a pre-reserved groove on the outer surface of the box, and a handle is provided on the front of the door. By providing a door, it is easy to open the door to remove the filter assembly, and it is also easy to check the working status of the filter assembly and change the storage volume of the solution in the box.

[0012] Furthermore, a rotatable fan is installed at the output end of the gas-gathering frame. The fan is used to quickly discharge the filtered gas. By setting up the fan, it is easy to blow the fan to rotate when the gas is discharged to the outside. The rotation of the fan can accelerate the air flow rate in the gas-gathering frame and improve the gas discharge efficiency.

[0013] Compared with existing technologies, this spherical graphite gas emission filter has the following advantages:

[0014] 1. This utility model, by setting a conversion mechanism, can facilitate the filtration of harmful gases generated after the high-temperature purification of spherical graphite. It can facilitate multiple filtration and purification of gases such as carbon monoxide and carbon dioxide, and can facilitate the conversion of carbon monoxide into carbon dioxide and its emission through chemical catalyst solutions, thereby reducing air pollution. Through the dual physical and chemical treatment of the gas, it ensures that the gas will not cause air pollution after emission, and can effectively filter the harmful gases generated by the high-temperature purification of spherical graphite.

By setting a filter component, it can facilitate the initial filtration of harmful gases produced after high-temperature purification of spherical graphite, and can filter and block larger particles in the harmful gases. By setting an output pipe, it can facilitate the extraction of the solution in the conversion box.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] As described in the background section, traditional spherical graphite generates a large amount of gas during high-temperature purification in a purification workshop, such as carbon monoxide and carbon dioxide due to incomplete combustion. If emitted to the outside, these gases will pollute the environment. Therefore, this embodiment provides a spherical graphite gas emission filtration device. This device can perform multiple filtrations on the gas generated after high-temperature purification of spherical graphite. Through dual physical and chemical treatment of the gas, it ensures that the gas will not pollute the air after emission.

[0023] See Figure 1 - Figure 4 This embodiment proposes a spherical graphite gas emission filtration device, including a housing 1. A conversion mechanism 2 is provided inside the housing 1. The conversion mechanism 2 includes a filter box 202 fixed to the inner wall of the housing 1, and a first vent pipe 201 connected to the filter box 202 and penetrating the inner wall of the housing 1. A filter assembly is provided inside the filter box 202.

[0024] refer to Figures 1 to 4 The conversion mechanism 2 facilitates the filtration of harmful gases produced after the spherical graphite is purified at high temperature. It facilitates multiple filtration and purification of gases such as carbon monoxide and carbon dioxide, and facilitates the conversion of carbon monoxide into carbon dioxide through chemical catalyst solutions and other agents for emission, thereby reducing air pollution.

[0025] As a supplement, chemical catalysts used to convert carbon monoxide into carbon dioxide, such as iron-chromium and copper-zinc catalysts, can be combined with water resources to convert carbon monoxide into gases that do not pollute the air and are then discharged.

[0026] The conversion mechanism 2 also includes a conversion box 203 fixedly connected to the bottom wall of the box 1, and a second vent pipe 204 connected to the filter box 202 and passing through the conversion box 203. A one-way vent valve 205 is installed at the lower end of the second vent pipe 204.

[0027] By setting up the conversion box 203, it is convenient to store the mixture of chemical reagents and water resources, so that the carbon monoxide produced by the incomplete combustion of spherical graphite can be converted into carbon dioxide that does not pollute the air and then emitted through the mixture.

[0028] Mixtures for carbon monoxide conversion, such as iron-chromium and copper-zinc compounds, can be combined with water resources to convert carbon monoxide into gases that do not pollute the air, thus avoiding air pollution caused by carbon monoxide emissions.

[0029] Furthermore, the upper surface of the conversion box 203 is fixedly connected to the gas gathering frame 206, and the output end of the gas gathering frame 206 penetrates the inner top wall of the box body 1.

[0030] By setting up the gas collection frame 206, it is easy to guide the emission of the filtered and converted pollution-free gas. It is also possible to quickly extract and discharge the gas in the conversion box 203 through an external air extraction device. The conversion box 203 is made of transparent material, which makes it easy to check the storage level of the solution in the conversion box 203 and whether it needs to be replaced.

[0031] The filter assembly includes a filter screen 3 and an activated carbon layer 4 located inside the filter box 202, as well as a pull plate 5 connected to the filter screen 3 and the activated carbon layer 4. By setting up the filter assembly, it is possible to perform the first filtration of harmful gases generated after the spherical graphite is purified at high temperature. It can filter and block larger particles in the harmful gases, thereby reducing the burden of subsequent secondary treatment of toxic gases and improving the filtration and emission efficiency of harmful gases.

[0032] The pull plate 5 facilitates the removal of the filter screen 3 and activated carbon layer 4. Furthermore, when installing the filter screen 3 and activated carbon layer 4, the pull plate 5 ensures close contact with the filter box 202, preventing harmful gases from leaking from the connection point.

[0033] The inner wall of the conversion box 203 is fixedly connected to the output pipe 6 and the input pipe 7, and the outer ends of the output pipe 6 and the input pipe 7 pass through the conversion box 203 and the box body 1 in sequence and extend to the outside of the box body 1.

[0034] By setting the output pipe 6, it is easy to extract the solution in the conversion box 203, and the solution can be filled into the conversion box 203 through the input pipe 7. The ends of the output pipe 6 and the input pipe 7 inside the conversion box 203 are both located at the bottom of the conversion box 203, which facilitates the extraction and filling of the solution.

[0035] The outer surface of the housing 1 has a reserved groove for hinged door 8, and the front of door 8 is provided with a handle. By providing door 8, it is easy to open door 8 to take out the filter assembly, and it is easy to check the working status of the filter assembly and the storage amount of solution in the conversion box 203.

[0036] A rotatable fan 9 is installed at the output end of the gas collection frame 206. The fan 9 is used to quickly discharge the filtered gas. By setting the fan 9, it is easy to blow the fan 9 to rotate when the gas is discharged to the outside, so that the fan 9 can quickly discharge the purified gas in the conversion box 203 and improve the efficiency of gas discharge.

[0037] Working principle: When spherical graphite is processed and purified at high temperature, the gas generated during the purification process is transmitted to the filter box 202 through the first vent pipe 201, which is tightly connected to the exhaust port of the high-temperature purification chamber. The filter screen 3 and activated carbon layer 4 in the filter box 202 perform the first filtration of the gas, which can facilitate the initial filtration of larger particles in the gas. Then, the gas is transmitted to the bottom of the conversion box 203 through the second vent pipe 204. The mixed solution in the conversion box 203, such as iron-chromium system, copper-zinc system, etc., is mixed with water to convert carbon monoxide in the gas into harmless carbon dioxide. This can filter and convert the carbon monoxide generated during the high-temperature purification of spherical graphite, so that the harmless carbon dioxide can be quickly discharged by the fan 9.
