Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully communicated to those skilled in the art. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0023] See Figures 1 to 5, the preferred structure of the grille hopper in this embodiment is shown in the figure. As shown in the figure, the grille hopper includes: a housing 1, a hopper core 2, and an auxiliary mechanism 3. Among them, the housing 1 is a trapezoidal cone structure with a hollow interior. The top of the housing 1 ( Figure 1 the upper part shown) is open, and the bottom of the housing 1 ( Figure 1 the lower part shown) is closed. Moreover, a discharge port is provided at the bottom of the housing 1, and the cross-sectional dimension of the bottom of the housing 1 is smaller than that of the top. Specifically, the interior of the housing 1 is hollow, the housing 1 is in the shape of a trapezoidal cone as a whole, and the cross-section of the housing 1 is a quadrilateral. The top of the housing 1 is the end with a larger cross-sectional dimension, and the bottom is the end with a smaller cross-sectional dimension.

[0024] The hopper core 2 is also a trapezoidal cone structure with a hollow interior. The hopper core 2 is arranged inside the housing 1, and there is a preset gap between the hopper core 2 and the housing 1. This preset gap can be determined according to the actual situation, and this embodiment does not impose any restrictions on it. The top of the hopper core 2 ( Figure 2 the upper part shown) is open, and the bottom of the hopper core 2 ( Figure 2 the lower part shown) is closed and provided with a discharge port, and the discharge port corresponds to the discharge port to receive the gas to be treated. Then, the gas to be treated sequentially passes through the discharge port and the discharge port, and then is conveyed into the interior of the hopper core 2. Moreover, the cross-sectional dimension of the bottom of the hopper core 2 is smaller than that of the top, and the interior of the hopper core 2 is used to hold the adsorbent. Specifically, the interior of the hopper core 2 is hollow, the hopper core 2 is in the shape of a trapezoidal cone as a whole, and the cross-section of the hopper core 2 is a quadrilateral. The top of the hopper core 2 is the end with a larger cross-sectional dimension, and the bottom is the end with a smaller cross-sectional dimension. The overall shape of the hopper core 2 is the same as that of the housing 1, but the overall size of the hopper core 2 is smaller than that of the housing 1. The hopper core 2 is placed inside the housing 1, and there is a preset gap between the outer wall of the hopper core 2 and the inner wall of the housing 1 to form a welding channel.

[0025] See Figure 4 , preferably, a connecting block 4 is provided between the outer wall of the hopper core 2 at the top and the inner wall of the housing 1. The setting of the connecting block 4 can not only connect the hopper core 2 and the housing 1 together, but also make there be a preset gap between the hopper core 2 and the housing 1. The connecting block 4 can be a round steel plug weld.

[0026] The auxiliary mechanism 3 is arranged inside the hopper core 2. The auxiliary mechanism 3 is used to promote the adsorption between the gas to be treated and the adsorbent, so that the gas to be treated and the adsorbent are effectively in contact, and the adsorption effect of the adsorbent is improved.

[0027] During specific implementation, both the housing 1 and the hopper core 2 can be made of steel plates. In this embodiment, Q345B steel plates are used to improve the processing accuracy of the grille hopper.

[0028] During specific implementation, valves are provided at both the discharge port and the discharge port.

[0029] It can be seen that in this embodiment, both the housing 1 and the hopper core 2 are trapezoidal pyramid structures with hollow interiors. The hopper core 2 is placed inside the housing 1, and the interior of the hopper core 2 contains an adsorbent. The gas to be treated is transported from the bottom of the hopper core 2 to the interior of the hopper core 2, and the gas to be treated comes into effective contact with the adsorbent, improving the adsorption effect. The auxiliary mechanism 3 can promote the adsorption between the gas to be treated and the adsorbent, further improving the adsorption effect of the adsorbent, and thus improving the treatment effect of the gas to be treated. When the grid hopper is used in a desulfurization device, it can effectively improve the desulfurization effect of the gas to be treated, solving the problem of poor desulfurization effect of the grid hopper in the prior art.

[0030] See Figures 2 to 4 In the above-mentioned embodiment, the auxiliary mechanism 3 may include: a plurality of grid plates 31. Among them, the grid plates 31 are arranged in parallel, that is, the grid plates 31 are parallel to each other, and there is a certain distance between any two adjacent grid plates 31. This distance can be determined according to the actual situation, and this embodiment does not make any restrictions on this.

[0031] Each grid plate 31 is arranged at intervals along the height direction of the hopper core 2 ( Figure 2 the direction from top to bottom shown in the figure) on the inner wall of the hopper core 2. Specifically, the hopper core 2 has four side walls, and a plurality of grid plates 31 are arranged on the inner walls of these four side walls. Each grid plate 31 on the inner wall surface of each side wall is arranged at intervals along the height direction of the hopper core 2. Preferably, the grid plates 31 are evenly distributed on the inner wall surfaces of each side wall. In the cross-sectional direction of the hopper core 2, the grid plates 31 on the inner wall surfaces of the four side walls of the hopper core 2 are also in the same cross-section, and the grid plates 31 are connected in sequence to form a circular ring, and a plurality of circular rings are arranged at intervals along the height direction of the hopper core 2.

[0032] Each grid plate 31 is inclined towards the bottom of the hopper core 2. Specifically, each grid plate 31 on the inner wall surface of each side wall is inclined, and one end of each grid plate 31 is connected to the inner wall surface of the side wall, and the other end of each grid plate 31 is inclined towards the bottom of the hopper core 2, that is, inclined downward.

[0033] Preferably, the angle β between each grid plate 31 and the horizontal cross-sectional line of the hopper core 2 is 30° - 35°. Among them, the horizontal cross-sectional line of the hopper core 2 is the horizontal line where the cross-section of the hopper core 2 is located. The horizontal direction of the hopper core 2 is perpendicular to the height direction of the hopper core 2, so each horizontal cross-sectional line is perpendicular to the height direction of the hopper core 2.

[0034] More preferably, the angle β between each grid plate 31 and the horizontal cross-sectional line of the hopper core 2 is 35°.

[0035] In specific implementation, each grid plate 31 can be a flat steel of -8*80.

[0036] In this embodiment, the inner wall surface of each side wall of the bucket core 2 is divided into 38 segments, with each segment having a distance of 60 mm, and the total length of each side wall is 2280 mm. A grid plate 31 is provided on each segment.

[0037] It can be seen that in this embodiment, by providing a plurality of grid plates 31, each grid plate 31 blocks the airflow to be treated, increases the flow path of the airflow to be treated, extends the residence time of the airflow to be treated, and further increases the contact time between the airflow to be treated and the adsorbent, enabling the airflow to be treated and the adsorbent to make full and effective contact and adsorption. It can also increase the contact area between the airflow to be treated and the adsorbent, improving the adsorption effect.

[0038] See Figure 2 and Figure 3 In the above embodiments, the bucket core 2 may include: a bottom plate, four corner folding plates 21, and four trapezoidal connecting plates 22. Among them, the four corner folding plates 21 are inclined, and the four corner folding plates 21 are respectively arranged at the four corners. Each connecting plate 22 is inclined, and a connecting plate 22 is arranged between any two adjacent corner folding plates 21. The four corner folding plates 21 and the four connecting plates 22 form a hollow trapezoidal cone.

[0039] The bottom plate is arranged at the bottom of the trapezoidal cone, and the bottom plate seals the trapezoidal cone, so the bottom plate is connected to the four corner folding plates 21 and the four connecting plates 22. The discharge port is opened on the bottom plate.

[0040] A plurality of grid plates 31 are provided on each inner wall surface of the trapezoidal cone. Specifically, a plurality of grid plates 31 are provided on the inner wall surfaces of the four connecting plates 22, and the two ends of each grid plate 31 respectively extend towards the corner folding plates 21 on both sides of the connecting plate 22.

[0041] During specific implementation, the bottom plate may be formed by butt-welding four plates, and an opening is left at the center of the four plates, and this opening is the discharge port.

[0042] During specific implementation, the four corner folding plates 21, the four connecting plates 22, and the bottom plate may all be steel plates with a thickness of 8 mm, and this steel plate may be Q345B.

[0043] It can be seen that in this embodiment, the structure of the bucket core 2 is simple and easy to implement.

[0044] See Figure 2 and Figure 3 In the above embodiments, the bucket core 2 further includes: a plurality of first reinforcing bodies 23 and four second reinforcing bodies 24. Among them, each outer wall surface of the trapezoidal cone is along the height direction of the bucket core 2 ( Figure 2A plurality of first reinforcing bodies 23 are arranged at intervals in the vertically downward direction as shown. Specifically, each outer wall surface of the trapezoidal cone is the outer wall surface of each connecting plate 22 and the outer wall surfaces of the corner folding plates 21 on both sides of the connecting plate 22. That is to say, a plurality of first reinforcing bodies 23 are arranged at intervals on the outer wall surface of each connecting plate 22 from the top to the bottom of the connecting plate 22, and each first reinforcing body 23 extends towards the corner folding plates 21 on both sides of the connecting plate 22. The top of the connecting plate 22 corresponds to the top of the bucket core 2, and the bottom of the connecting plate 22 corresponds to the bottom of the bucket core 2. Preferably, the first reinforcing bodies 23 are evenly distributed on each outer wall surface of the trapezoidal cone. The first reinforcing bodies 23 are arranged side by side, that is, the first reinforcing bodies 23 are parallel to each other.

[0045] Each second reinforcing body 24 is respectively arranged on the inner walls of the four connecting plates 22. Then, the four second reinforcing bodies 24 correspond to the four connecting plates 22 one by one, and one second reinforcing body 24 is arranged on the inner wall of each connecting plate 22. Each second reinforcing body 24 is perpendicularly connected to a plurality of grid plates 31 on the corresponding connecting plate 22. Specifically, each second reinforcing body 24 is attached to the corresponding connecting plate 22, and each second reinforcing body 24 extends from the top to the bottom of the connecting plate 22. Among them, the top of the connecting plate 22 corresponds to the top of the bucket core 2, and the bottom of the connecting plate 22 corresponds to the bottom of the bucket core 2. Each second reinforcing body 24 is perpendicular to the grid plates 31 on the corresponding connecting plate 22.

[0046] During specific implementation, each second reinforcing body 24 can be connected to all the grid plates 31 on the corresponding connecting plate 22, or each second reinforcing body 24 can be connected to some of the grid plates 31 on the corresponding connecting plate 22. Among them, the connected part of the grid plates 31 is the grid plates 31 at the top and middle of the connecting plate 22.

[0047] During specific implementation, each first reinforcing body 23 and each second reinforcing body 24 can both be angle steels.

[0048] It can be seen that in this embodiment, the settings of the first reinforcing bodies 23 and the second reinforcing bodies 24 can effectively improve the strength of the bucket core 2, and the second reinforcing bodies 24 can play a role in fixing the grid plates 31 on the connecting plates 22, preventing the grid plates 31 from falling off, especially preventing the grid plates 31 at the top of the connecting plate 22 from falling off, and effectively protecting the grid plates 31.

[0049] See Figure 1 , in the above embodiments, the housing 1 may include: four trapezoidal support plates 11, a sealing plate, and a reinforcing mechanism. Among them, the support plates 11 are all inclined, and the support plates 11 are sequentially connected to form a hollow trapezoidal cone. The sealing plate is arranged at the bottom of each support plate 11, and the sealing plate seals the bottom of each support plate 11. The discharge port is opened on the sealing plate.

[0050] Reinforcing mechanisms are provided on each support plate 11 to increase the strength of the support plate 11, thereby increasing the strength of the housing 1.

[0051] The reinforcing mechanisms may include: a plurality of first reinforcing plates 12 and four second reinforcing plates 13. Among them, a plurality of first reinforcing plates 12 are spaced along the height direction of the housing 1 ( Figure 1 the direction from top to bottom as shown) on the outer wall of each support plate 11. Specifically, the first reinforcing plates 12 are spaced from the top to the bottom of the support plate 11. Preferably, the first reinforcing plates 12 are evenly distributed. Among them, the top of the support plate 11 corresponds to the top of the housing 1, and the bottom of the support plate 11 corresponds to the bottom of the housing 1. The first reinforcing plates 12 are arranged in parallel, that is, the first reinforcing plates 12 are parallel to each other.

[0052] Each second reinforcing plate 13 is respectively arranged on the outer wall of each support plate 11. Specifically, each second reinforcing plate 13 corresponds to each support plate 11 one by one. Each second reinforcing plate 13 is attached to the outer wall of the corresponding support plate 11, and each second reinforcing plate 13 is perpendicularly connected to each first reinforcing plate 12 on the corresponding support plate 11.

[0053] In specific implementation, each support plate 11 and the plugging plate may be steel plates with a thickness of 10 mm, and the steel plates may be Q345B.

[0054] It can be seen that in this embodiment, the structure of the housing 1 is simple and easy to implement. The arrangement of the reinforcing mechanisms can effectively increase the strength of the housing 1 and extend the service life of the housing 1.

[0055] Refer to Figure 5 , in the above embodiments, the grille bucket may further include: four anti-ash accumulation wall plates 5. Among them, each anti-ash accumulation wall plate 5 is inclined. The four anti-ash accumulation wall plates 5 correspond to the four inner wall surfaces of the housing 1 one by one. The anti-ash accumulation wall plates 5 are arranged at the top of the housing 1. The first end ( Figure 5 the lower end as shown) of each anti-ash accumulation wall plate 5 is connected to the top of the corresponding inner wall surface of the housing 1, and the second end ( Figure 5 the upper end as shown) of each anti-ash accumulation wall plate 5 is placed outside the housing 1 and extends away from the top of the housing 1, and the second end of each anti-ash accumulation wall plate 5 is used to be connected to the installation structure 6. Among them, the installation structure 6 is the structure adjacent to the grille bucket. When the grille bucket is applied to a desulfurization device, the installation structure 6 may be an air chamber wall plate.

[0056] It can be seen that in this embodiment, the installation structure 6 is arranged adjacent to the grid hopper, and the installation structure 6 is arranged vertically. There is a certain distance between the top of the housing 1 and the installation structure 6. In this way, dust easily falls into the area between the housing 1 and the installation structure 6, which is not convenient for cleaning. The dust-proof wall panel 5 shields the area between the housing 1 and the installation structure 6, so that the dust can slide down from the dust-proof wall panel 5, and there is no need to clean the area between the housing 1 and the installation structure 6, which is simple and convenient.

[0057] In summary, in this embodiment, both the housing 1 and the hopper core 2 are trapezoidal pyramid structures with hollow interiors. The hopper core 2 is placed inside the housing 1, and the interior of the hopper core 2 contains an adsorbent. The gas to be treated is transported from the bottom of the hopper core 2 to the inside of the hopper core 2, and the gas to be treated makes effective contact with the adsorbent, improving the adsorption effect. The auxiliary mechanism 3 can promote the adsorption between the gas to be treated and the adsorbent, further improving the adsorption effect of the adsorbent, achieving efficient adsorption, and thus improving the treatment effect of the gas to be treated. When the grid hopper is used in a desulfurization device, it can effectively improve the desulfurization effect of the gas to be treated.
