Description

Technical Field

[0001] The present specification relates to the technical field of sewage treatment, and in particular to a high-flow, high-slag, high-efficiency, and low-energy consumption grid. Background Art

[0002] The screen is the most important auxiliary equipment in the sewage pumping station. The screen is generally composed of a group of parallel bars, which are placed obliquely at the inlet of the pumping station sump, and its inclination angle is generally 70°~80°.

[0003] However, the contact area between the existing grating and the sewage is not large, and the treatment efficiency is not high; and the slag cleaning of the grating needs to be washed by flushing water separately, and the slag cleaning efficiency is low. The slag cleaning rake teeth are usually fixed structures. When the grating is filtering sewage, if there are stones, branches or other large solids in the sewage, it is easy to get stuck between the bars. When the slag cleaning is working, it is easy to cause the rake teeth to be stuck or overloaded, resulting in grating failure or abnormal movement. In addition, the existing gratings are usually fixedly installed with bolts on the grating channel surface. When the grating is inspected and maintained, it is usually necessary to disassemble the grating as a whole and move it out of the canal before the grating can be inspected and maintained. This makes it more difficult to inspect and maintain the grating and seriously affects the operation of the sewage treatment plant. Utility Model Content

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0040] See also Figures 1 to 5 The embodiment of the present application provides a high-flow, high-slag-removal, high-efficiency, low-energy-consumption grid, comprising a mounting frame 1 , a grid 2 , a driving gear 31 , a steering gear 32 , a driving chain 33 , a driving member 34 , a rotary rake 4 , and an elastic member 5 .

[0041] Among them, Figure 1 As shown, the mounting frame 1 includes a connected vertical section 11 and an inclined section 12. The grid 2 is fixedly arranged at the bottom of the inclined section 12. The angle α between the grid 2 and the horizontal plane 300 is 30° to 70°. Figure 1 , the sewage inflow direction X is shown in FIG. The driving gear 31 is arranged inside the vertical section 11 and close to the top of the vertical section 11. The steering gear 32 is arranged inside the inclined section 12 and close to the bottom of the inclined section 12, and the steering gear 32 is located above the grid 2. The driving chain 33 is sleeved outside the driving gear 31 and the steering gear 32, and the driving chain 33 is respectively engaged with the driving gear 31 and the steering gear 32. The driving member 34 is fixedly arranged outside the vertical section 11, connected to the driving gear 31, and is used to drive the driving gear 31 to rotate, so as to drive the driving chain 33 and the steering gear 32 to rotate. The rotating rake teeth 4 are installed on the driving chain 33, move with the driving rack, and are used to clean the grid 2. The elastic member 5 is installed on the driving chain 33, and the rotating rake teeth 4 can rotate and compress the elastic member 5 to pass through the obstacle 200.

[0042] The high-flow, high-slag efficiency and low-energy consumption grid provided in this embodiment can increase the contact area between the grid 2 and the sewage by setting the angle α between the grid 2 and the horizontal plane 300 to 30°~70°, thereby increasing the amount of water flowing through the grid per unit time, so that the grid has the advantage of high flow and improves the processing efficiency of the grid.

[0043] In addition, by setting the driving gear 31, the steering gear 32, the driving chain 33 and the driving member 34, the movement of the rotary rake teeth 4 is realized, and when the moving rotary rake teeth 4 contact the grid 2, the slag on the grid 2 can be effectively and automatically cleaned without flushing water, so as to improve the slag cleaning efficiency of the grid, and the use of the driving gear 31, the steering gear 32, the driving chain 33 and the driving member 34 as the driving system can reduce energy consumption. By reasonably setting the position of the elastic member 5 and the rotary rake teeth 4 relative to the driving chain 33, the rotary rake teeth 4 can move to avoid obstacles 200 when encountering them, avoiding shutdown for maintenance and improving work efficiency.

[0044] Preferably, the angle α between the grid 2 and the horizontal plane 300 is 30° to 36°, and this angle range can further increase the contact area between the grid 2 and the sewage. The grid 2 with an inclination angle of 30° to 36° is located below the sewage surface and is used to filter the screen residue; the vertical section 11 of the mounting frame 1 is used to lift the residue, and the lifting direction is the vertical direction, and the angle with the horizontal plane 300 is 90°; the two form a variable angle grid.

[0045] In this embodiment, the vertical section 11 includes two first side walls 111, a back plate 112 and a baffle 113. The two first side walls 111 are arranged opposite to each other, and the first side wall 111 is perpendicular to the back plate 112. The inner side of each of the two first side walls 111 is provided with a driving gear 31 and a part of the driving chain 33, and the two driving gears 31 are arranged in alignment. Figure 3 As shown, the two driving gears 31 are connected by a horizontally extending driving shaft 35, and the driving member 34 is connected to one end of the driving shaft 35 and drives the driving shaft 35 to rotate, so that the driving shaft 35 drives the two driving gears 31 to rotate. The driving member 34 is arranged on the outside of one of the first side walls 111, and the driving member 34 is preferably a motor. The baffle 113 and the back plate 112 are arranged opposite to each other, the back plate 112 is a solid plate, and the baffle 113 can be provided with a transparent observation window to facilitate observation of the slag lifting situation in the vertical section 11.

[0046] Specifically, the inclined section 12 includes two second side walls 121 that are oppositely arranged, and the second side walls 121 are parallel to and integrally arranged with the first side wall 111. The inner sides of the two second side walls 121 are each provided with a steering gear 32 and the remaining portion of the driving chain 33, and the two steering gears 32 are aligned. The top edge 1211 and the bottom edge 1212 of the second side wall 121 are both inclined. The grid 2 is fixedly arranged between the bottom edges 1212 of the two second side walls 121. In one embodiment, the top edge 1211 and the bottom edge 1212 of the second side wall 121 are both arranged parallel to the grid 2, which can make the structure smoother.

[0047] like Figure 2 As shown, a rotating shaft 91 is disposed on the outer side of the first side wall 111, and a support seat 92 is connected to the side of the rotating shaft 91 away from the first side wall 111, and the support seat 92 is used to support the grille on the working surface 100. The rotating shaft 91 is rotatably connected to the first side wall 111 or the support seat 92, so that the grille as a whole can rotate around the rotating shaft 91.

[0048] Specifically, a lifting ring 10 is provided on the top edge 1211 of the second side wall 121 for connecting a lifting tool, so that the grille can be directly swung out of the ditch by pulling the lifting tool manually or with an electric hoist, which is very easy to maintain and greatly facilitates maintenance personnel.

[0049] Figure 4 and Figure 5 The moving direction Y of the drive chain 33 is shown in FIG. Figure 4 As shown, the driving chain 33 is fixedly provided with a first connecting plate 6 for fixing one end of the elastic member 5 and the middle portion 72 of the movable slag blocking plate 7 so that the two are fixed to the driving chain 33. One end of the elastic member 5 is fixedly connected to the first connecting plate 6, and the elastic member 5 is perpendicular to the driving chain 33. The elastic member 5 is preferably a spring.

[0050] A movable slag blocking plate 7 is provided between the rotary rake teeth 4 and the first connecting plate 6, one end of the rotary rake teeth 4 is fixedly connected to the movable slag blocking plate 7 by a first fastener 81, and the middle portion 72 of the movable slag blocking plate 7 is fixedly connected to the first connecting plate 6 by a second fastener 82. One end of the movable slag blocking plate 7 close to the rotary rake teeth 4 is fixedly connected to one end of the elastic member 5 away from the first connecting plate 6.

[0051] At least part of the rotating rake teeth 4 extends out of one end of the movable slag blocking plate 7 connected to the elastic member 5, and is used to contact the grid 2 to clean the grid 2. In the initial state, the rotating rake teeth 4 and the elastic member 5 are arranged in parallel, and the rotating rake teeth 4 are perpendicular to the plane of the grid 2 when contacting the grid 2. The initial state refers to the state when the rotating rake teeth 4 avoid the obstacle 200, and the rotating rake teeth 4 are in the initial state when they do not avoid the obstacle 200.

[0052] The two ends of the rotary rake teeth 4 have the same structure and material, and the material can be bronze. In this way, after one end is worn, the rotary rake teeth 4 can be removed, and the two ends can be swapped and the other end can be used as a part for cleaning the grating, thereby extending the service life of the rotary rake teeth 4.

[0053] Specifically, the end of the movable slag baffle plate 7 away from the rotary rake teeth 4 is a free end 71, and the free end 71 is located on a side of the middle portion 72 away from the elastic member 5. The middle portion 72 of the movable slag baffle plate 7 is fixed to the driving chain 33.

[0054] The rotary rake teeth 4 in this embodiment are in a swingable structure, and when encountering an obstacle, they automatically swing over the obstacle 200 and then automatically return to their original position. Figure 5 As shown, when the rotating rake teeth 4 encounter an obstacle 200, the lower end of the rotating rake teeth 4 moves to the right, driving the lower end of the movable slag blocking plate 7 to move to compress the elastic member 5 upward, the middle part 72 of the movable slag blocking plate 7 remains stationary, and the free end 71 moves downward. After the rotating rake teeth 4 are lifted over the obstacle 200, the elastic member 5 returns downward and then pushes the rotating rake teeth 4 back through the lower end of the movable slag blocking plate 7, completing the obstacle avoidance process of the rotating rake teeth 4.

[0055] In one embodiment, the grid 2 may be in a strip shape, including a plurality of bars arranged in parallel, and the distance between adjacent bars is 1 mm to 60 mm. It may be used as a fine grid or a coarse grid and is suitable for different demand scenarios.

[0056] In other embodiments, the grid 2 may be in a hole shape, including a plurality of through holes, and the hole diameter may be 15 mm, 20 mm, etc., which may be selected according to needs.

[0057] In this embodiment, a slag discharge area 20 is provided at the upper rear end corresponding to the vertical section 11 of the mounting frame 1, and an opening is provided above the back plate 112 corresponding to the slag discharge area 20. A nylon scraper is provided at the slag discharge area 20, and a fixed point is provided at the upper part of the nylon scraper, and the nylon scraper is connected to the fixed point through a second connecting plate. The lower end of the second connecting plate is fixedly connected to the nylon scraper, and the upper end can rotate around the fixed point. Therefore, when the rotating rake teeth 4 moving with the driving chain 33 carry the screen residue cleaned from the grid 2 and run upward to the slag discharge area 20, the nylon scraper will contact the inner side of the rotating rake teeth 4 and move relative to the rotating rake teeth 4, thereby pushing the screen residue off the rotating rake teeth 4 and discharging it from the slag discharge area 20 on the grid.

[0058] It should be noted that, in the description of this specification, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of this specification, unless otherwise specified, the meaning of "plurality" is two or more.

[0059] Any numerical value cited herein includes all values ​​of lower and upper values ​​that increase by one unit from the lower limit to the upper limit, and there is at least a two-unit interval between any lower value and any higher value. For example, if the value of the quantity of a component or a process variable (such as temperature, pressure, time, etc.) is stated to be from 1 to 90, preferably from 20 to 80, and more preferably from 30 to 70, the purpose is to illustrate that values ​​such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 are also explicitly listed in the specification. For values ​​less than 1, one unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples that are intended to be clearly expressed, and it can be considered that all possible combinations of numerical values ​​listed between the lowest value and the highest value are clearly stated in the specification in a similar manner.

[0060] Unless otherwise indicated, all ranges include the endpoints and all numbers between the endpoints. "About" or "approximately" used with a range applies to both endpoints of the range. Thus, "about 20 to 30" is intended to cover "about 20 to about 30", including at least the specified endpoints.
