Description

Technical Field

[0001] This invention belongs to the technical field of waste gas treatment, specifically relating to an internal inlet plate type bar screen cleaner. Background Technology

[0002] In the existing technology, the internal flow type bar screen cleaner introduces water into the machine casing, and uses a ring-shaped bar screen structure to remove debris and other things that need to be cleaned from the water and collect them. Compared with the bar screen mechanism commonly used in the existing technology, it is more efficient and has a more reasonable structural design.

[0003] In the prior art, the structural design of internal flow type bar screen cleaning devices usually requires the installation of internal bar screen components. You can refer to the "An Internal Flow Type Bar Screen Cleaner" disclosed in Publication (Announcement) No.: CN221253993U. This technical solution is relatively novel. It sets the internal bar screen components as a triangular ring structure instead of a straight up and down ring structure, which can increase the cleaning efficiency.

[0004] However, existing technologies still have significant drawbacks. In existing technologies, the grilles can usually only rotate in one direction and can only clean one area, resulting in low work efficiency. There are also large dead corners inside the casing, and cleaning can only be achieved by relying on water flow to carry the debris to the cleaning area, which is not efficient.

[0005] To solve the above-mentioned technical problems, it is necessary to develop a reasonably structured, internally inlet plate bar screen cleaning machine that improves work efficiency. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an internally inlet plate type bar screen cleaning machine; its technical solution is as follows:

[0007] An internal flow plate-type bar screen cleaner includes a casing, inside which are arranged two sets of identical first plate-type bar screens and a second plate-type bar screen. A fixed shaft shared by the first and second plate-type bar screens is arranged at the lower middle position of the casing. A first roller and a second roller are mounted on the fixed shaft. Several of the first roller and the second roller are arranged on the fixed shaft, and the two sets of rollers are arranged alternately and at intervals. Both sets of rollers can rotate on the fixed shaft.

[0008] The first plate grid assembly includes a first drive roller and a first conveyor belt; the second plate grid assembly includes a second drive roller and a second conveyor belt. The first drive roller and the second drive roller are respectively disposed on the upper left and right sides of the machine housing, such that the two drive shafts are respectively located on the upper left and right sides of the fixed shaft. The first conveyor belt is correspondingly fitted onto the first roller of the fixed shaft and the first drive roller on the left side, and the second conveyor belt is correspondingly fitted onto the second roller of the fixed shaft and the second drive roller on the right side, such that the first conveyor belt and the second conveyor belt are both arranged in a symmetrical oblique V-shape within the machine housing.

[0009] Both the first and second conveyor belts are equipped with transverse grid plates, and the first drive roller on the left rotates counterclockwise, while the second drive roller on the right rotates clockwise. The first conveyor belt is lifted to the left to remove contaminants, and the second conveyor belt is lifted to the right to remove contaminants.

[0010] Furthermore, inlets are provided on both sides of the lower end of the housing, and the inlets are located above the fixed shaft.

[0011] Furthermore, a first sludge collection box is provided directly below the first drive roller, and a second sludge collection box is provided directly below the second drive roller. Debris on the first conveyor belt falls into the first sludge collection box, and debris on the second conveyor belt falls into the second sludge collection box.

[0012] Furthermore, the first roller and the second roller are alternately spaced on a fixed shaft. After the first conveyor belt and the second conveyor belt are fitted onto the first drive roller and the second drive roller, a left empty area is formed between adjacent first conveyor belts; a right empty area is formed between adjacent second conveyor belts.

[0013] The left empty area is provided with a third plate-type grid group, and the right empty area is provided with a fourth plate-type grid group; the third plate-type grid group and the fourth plate-type grid group have the same structural form.

[0014] Furthermore, the third plate grid assembly includes a third driven roller and a third driving roller; the fourth plate grid assembly includes a fourth driven roller and a fourth driving roller; the third driven roller and the fourth driven roller are respectively located on the left and right sides of the fixed shaft; while the third driving roller is located on the right side of the first driving roller, and the fourth driving roller is located on the left side of the second driving roller, and the third driving roller and the fourth driving roller are respectively located on both sides of the upper end of the intermediate shaft;

[0015] Several third conveyor belts are fitted between the third drive roller and the third driven roller, and the third conveyor belts pass through the empty area on the left side. Each third conveyor belt is equipped with a grid plate. Several fourth conveyor belts are fitted between the fourth drive roller and the fourth driven roller, and the fourth conveyor belts pass through the empty area on the right side.

[0016] Furthermore, the third and fourth conveyor belts are symmetrically arranged at an angle, with the third conveyor belt crossing the first conveyor belt in the empty area on the left, and the fourth conveyor belt crossing the second conveyor belt in the empty area on the right; the direction of movement of each conveyor belt is not affected.

[0017] Furthermore, the rotation direction of the third drive roller is set to clockwise, so that the third conveyor belt is lifted from the left side to achieve cleaning;

[0018] The fourth drive roller is set to rotate counterclockwise, so that the fourth conveyor belt is lifted from the right side to achieve cleaning.

[0019] Furthermore, an intermediate sludge collection box is provided directly below the first drive roller and the second drive roller, through which debris falling from the third and fourth conveyor belts is collected.

[0020] Furthermore, the first drive roller, the second drive roller, the third drive roller, and the fourth drive roller are all connected to drive motors, which are fixed to the machine housing. The first sludge collection box, the second sludge collection box, and the intermediate sludge collection box can all be fixed inside the machine housing or be configured as detachable structures that can be removed from the machine housing.

[0021] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0022] 1) The technical solution of the present invention completes the internal flow cleaning work through four sets of plate grilles, which can clean the inside of the casing completely without dead angles. The first and second plate grille sets are mainly responsible for cleaning the debris in the middle area, while the third plate grille set is responsible for cleaning the debris in the left area and the fourth plate grille set is responsible for cleaning the debris in the right area. The four sets of plate grilles work together to effectively improve the cleaning efficiency and quality.

[0023] 2) In this invention, the first plate grid group and the second plate grid group are respectively provided with a first conveyor belt and a second conveyor belt. The two are arranged in a V-shaped structure. One lifts and cleans the debris to the left and the other lifts and cleans the debris to the right. As long as the debris is located in the middle position, it can be cleaned. The structure is ingenious and reasonable.

[0024] 3) In this invention, the first conveyor belt and the second conveyor belt are respectively installed on the fixed shaft via the first roller and the second roller. The fixed shaft is shared. After the conveyor belt is fitted onto the drive roller, it forms a left empty area and a right empty area, which facilitates the subsequent installation of the third plate grid group and the fourth plate grid group.

[0025] 4) The third and fourth plate grid groups in this invention can be located in the debris in the left and right areas of the casing, respectively, and the third conveyor belt can be installed in the empty areas on the left and right sides, respectively. This increases the cleaning area while reducing the overall space occupied, resulting in a reasonable structure.

[0026] 5) The present invention also reasonably sets the positions of the first sewage collection box, the second sewage collection box and the intermediate sewage collection box, which can correspondingly receive the debris falling from the first conveyor belt, the second conveyor belt, the third conveyor belt and the fourth conveyor belt, and the structure is reasonable.

Detailed Implementation

[0036] The present invention will be further illustrated below with reference to specific embodiments. These embodiments are implemented based on the technical solutions of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0037] like Figure 1 As shown, an internal flow plate type bar screen cleaning machine includes a housing 1, inside which are arranged two sets of identical first plate bar groups and second plate bar groups; a fixed shaft 2 shared by the first plate bar groups and the second plate bar groups is arranged at the middle position of the lower end of the housing 1. A first roller 101 and a second roller 201 are mounted on the fixed shaft 2. Several first rollers 101 and several second rollers 201 are arranged on the fixed shaft 2, and the two sets of rollers are arranged alternately and at intervals, and both sets of rollers can rotate on the fixed shaft 2.

[0038] like Figure 2 As shown, the first plate grid assembly includes a first drive roller 102 and a first conveyor belt 103; the second plate grid assembly includes a second drive roller 202 and a second conveyor belt 203. The first drive roller 102 and the second drive roller 202 are respectively disposed on the upper left and right sides of the housing 1, so that the two drive shafts are respectively located on the upper left and right sides of the fixed shaft 2; the first conveyor belt is correspondingly mounted on the first roller 101 and the first drive roller 102 on the left side of the fixed shaft 2, and the second conveyor belt 203 is correspondingly mounted on the second roller 201 and the second drive roller 202 on the right side of the fixed shaft 2, so that the first conveyor belt 103 and the second conveyor belt 203 are symmetrically arranged in an oblique V-shape within the housing 1.

[0039] like Figure 3 and Figure 8 As shown, both the first conveyor belt 103 and the second conveyor belt 203 are provided with transverse grid plates 3, and the first drive roller 102 on the left side rotates counterclockwise, and the second drive roller 202 on the right side rotates clockwise. The first conveyor belt 103 is lifted to the left to remove dirt, and the second conveyor belt 203 is lifted to the right to remove dirt.

[0040] The lower end of the housing 1 is provided with inlet ports 4 on both sides, and the inlet ports 4 are located above the fixed shaft 2; a first sludge collection box 104 is provided directly below the first drive roller 102, and a second sludge collection box 204 is provided directly below the second drive roller 202. Debris on the first conveyor belt 103 falls into the first sludge collection box 104, and debris on the second conveyor belt 203 falls into the second sludge collection box 204.

[0041] The first roller 101 and the second roller 201 are alternately arranged on the fixed shaft 2. The first conveyor belt 103 and the second conveyor belt 203 are fitted after the first drive roller 102 and the second drive roller 202. A left empty area 5 is formed between adjacent first conveyor belts 103; a right empty area 6 is formed between adjacent second conveyor belts 203; a third plate grid group is provided in the left empty area 5, and a fourth plate grid group is provided in the right empty area 6; the third plate grid group and the fourth plate grid group have the same structural form.

[0042] like Figure 4 and Figure 5 As shown, the third plate grid assembly includes a third driven roller 301 and a third driving roller 302; the fourth plate grid assembly includes a fourth driven roller 401 and a fourth driving roller 402; the third driven roller 301 and the fourth driven roller 401 are respectively located on the left and right sides of the fixed shaft 2; while the third driving roller 302 is located on the right side of the first driving roller 102, and the fourth driving roller 402 is located on the left side of the second driving roller 202, and the third driving roller 302 and the fourth driving roller 402 are respectively located on both sides of the upper end of the intermediate shaft.

[0043] Several third conveyor belts 303 are fitted between the third drive roller 302 and the third driven roller 301. The third conveyor belts 303 pass through the empty area 5 on the left side. Each third conveyor belt 303 is provided with a grid plate 3. Several fourth conveyor belts 403 are fitted between the fourth drive roller 402 and the fourth driven roller 401. The fourth conveyor belts 403 pass through the empty area 6 on the right side.

[0044] like Figure 6 and Figure 7 As shown, the third conveyor belt 303 and the fourth conveyor belt 403 are symmetrically arranged at an angle. The third conveyor belt 303 crosses the first conveyor belt 103 in the empty area 5 on the left, and the fourth conveyor belt 403 crosses the second conveyor belt 203 in the empty area 6 on the right. The movement direction of each conveyor belt is not affected.

[0045] The rotation direction of the third drive roller 302 is set to clockwise, so that the third conveyor belt 303 is lifted from the left side to achieve cleaning; the rotation direction of the fourth drive roller 402 is set to counterclockwise, so that the fourth conveyor belt 403 is lifted from the right side to achieve cleaning.

[0046] An intermediate sludge collection box 7 is provided directly below the first drive roller 102 and the second drive roller, through which debris falling from the third conveyor belt 303 and the fourth conveyor belt 403 is collected.

[0047] The first drive roller 102, the second drive roller 202, the third drive roller 302 and the fourth drive roller 402 are all connected to drive motors 8, and the drive motors 8 are fixed on the housing 1. The first sludge collection box 104, the second sludge collection box 204 and the intermediate sludge collection box 7 can all be fixed inside the housing 1, or can be set as a detachable structure, so that they can be taken out from the housing 1.

[0048] This invention comprises four sets of plate grid groups, each with a different cleaning position. Firstly, the first and second plate grid groups are symmetrical V-shaped structures. The lower ends of the first conveyor belt 103 and the second conveyor belt 203 are mounted on a fixed shaft 2 via first rollers 101 and 201, while the upper ends are respectively fitted onto first drive rollers 102 and 202. Since the first rollers 101 and 201 are alternately fitted onto the fixed shaft 2, the first and second conveyor belts 103 and 203 are strip-shaped, forming a left-side empty area 5 and a right-side empty area 6. These empty areas are used to house the third and fourth plate grid groups, respectively, without affecting the cleaning of the first and second conveyor belts 203.

[0049] During the cleaning process, debris enters the casing 1 through the inlet 4. The first conveyor belt 103 on the left rotates counterclockwise and moves to the upper left. The debris is then lifted to the left by the grid plate 3 on the first conveyor belt 103 and flips after reaching the first drive roller 102. Since the first conveyor belt 103 is angled, the debris on the grid plate 3 falls into the first collection tank 104 after flipping. This is the cleaning process of the first conveyor belt 103. The cleaning process of the second conveyor belt 203 is the same as that of the first conveyor belt 103. The second conveyor belt moves to the right, so the debris is carried to the right and falls into the second collection tank 204 after flipping from the second drive roller 202, thus achieving cleaning.

[0050] The first conveyor belt 103 and the second conveyor belt 203 in this invention are mainly used to clean up debris in the middle area of ​​the inlet 4. The debris in this area can be lifted and carried away by the first conveyor belt 103 or the second conveyor belt 203. The lower ends of the two conveyor belts are installed on the same fixed shaft 2 by the first roller 101 and the second roller 201, without the need for separate shafts. The two conveyor belts can be cleaned and transported simultaneously by setting different conveying directions by the first drive roller 102 and the second drive roller 202 on the upper side. At the same time, according to the structural design, the left empty area 5 and the right empty area 6 are left for setting the third plate grid group and the fourth plate grid group.

[0051] The third and fourth plate grid groups of this invention are structurally identical, specifically including an upper driving roller, a lower driven roller, and a conveyor belt in the middle, with grid plates 3 mounted on the conveyor belt. However, the third and fourth plate grid groups in this invention are respectively located in the left empty area 5 and the right empty area 6. In this invention, the third driven roller 301 is located directly to the left of the intermediate shaft, the fourth driven roller 401 is located directly to the right of the intermediate shaft, the third driving roller 302 is located directly to the right of the first driving roller 102, and the fourth driving roller 402 is located directly to the left of the second driving roller 202. This arrangement ensures that both the third and fourth conveyor belts are obliquely positioned, and that the third conveyor belt is obliquely inserted into the left empty area 5 of the first conveyor belt 103, and the fourth conveyor belt is obliquely inserted into the right empty area 6 of the second conveyor belt 203, thus making reasonable use of the empty space on both sides.

[0052] Furthermore, by setting the rotation direction of the third drive roller 302 and the fourth drive roller 402, the third conveyor belt is lifted to the right. As a result, the debris located in the area on the left side of the inlet 4 will be lifted and carried away by the third conveyor belt. After passing the upper third drive roller 302, it falls into the lower intermediate sludge collection box 7. Similarly, the fourth conveyor belt is lifted to the left. As a result, the debris located in the area on the right side of the inlet 4 will be lifted and carried away by the fourth conveyor belt. After flipping over the fourth drive roller 402, the debris falls into the lower intermediate sludge collection box 7, completing the cleaning work.

[0053] The technical solution of this invention completes the internal cleaning work through four sets of plate grilles, which can clean the inside of the casing 1 completely without dead angles. The first and second plate grille sets are mainly responsible for cleaning debris in the middle area, while the third plate grille set is responsible for cleaning debris in the left area and the fourth plate grille set is responsible for cleaning debris in the right area. The four sets of plate grilles work together to effectively improve the cleaning efficiency and quality.

[0054] The above embodiments are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
