Description

Technical Field

[0002] The existing tunnel sewage treatment system uses a pump to pump sewage into a plate-and-frame filter press for mud-water separation. Because the tunnel sewage contains a large amount of mud and mud cleaning is frequent, the traditional method is to build a concrete foundation and use a steel frame to suspend the plate-and-frame filter press by more than 3 meters, so that a forklift or other pneumatic machinery can remove the mud from under the equipment. The plate-and-frame filter press has a heavy weight and a large investment in the equipment foundation. Steel parts must be embedded during foundation construction, which is complex to construct. At the same time, the overhead height requires a large investment in the supporting platform, and it is inconvenient to operate, clean and replace the filter cloth, which poses certain safety hazards. In addition, because it is a temporary facility, it is inconvenient to disassemble after construction, which increases the disassembly cost.

[0003] The prior art solves the above-mentioned problems by providing a hopper and a screw conveyor, such as the patent with publication number CN202478688U; however, it has the following shortcomings: the screw conveyor is arranged outside the hopper by welding or bolting. In the former, the screw conveyor cannot be disassembled, and its subsequent maintenance and replacement are troublesome; while in the latter, the weight of the screw conveyor is entirely borne by the bolts. Due to the long use time, vibration generated during use and other problems, the bolts may fail, and when the bolts fail, there is a safety hazard of the screw conveyor falling.

[0026] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0028] Example:

[0029] like Figure 1-Figure 7 As shown, a tunnel sewage treatment device that is easy to install includes a plate and frame filter press 1. A support frame 2 is provided at the bottom of the plate and frame filter press 1. The support frame 2 is connected to a mud collecting bucket 3. The mud collecting bucket 3 is arranged below the mud outlet end of the plate and frame filter press 1; a screw conveyor 4 is provided in the mud collecting bucket 3, and the screw conveyor 4 is detachably connected to the mud collecting bucket 3 through a connecting assembly.

[0030] The support frame 2 is arranged on the equipment skid 5, so that the entire device can be placed on an equipment skid, and the device foundation only needs to be leveled, and no pre-embedding is required. While reducing the investment in foundation construction, when the project is completed, it is also convenient to move it to others for use, reducing the cost of disassembly and construction.

[0031] like Figure 1-Figure 6 As shown, the connecting assembly includes a bracket 7, a fixing seat 8 and a pressing seat 9. The bracket 7 is welded and fixed on the screw conveyor 4. The bracket 7 is provided with a clearance groove 10.

[0032] The fixing seat 8 is fixedly arranged on the inner wall of the mud collecting bucket 3 , the fixing seat 8 is located in the giving way groove 10 , the pressing seat 9 is detachably connected to the fixing seat 8 , and the bracket 7 is pressed on the inner wall of the mud collecting bucket 3 through the pressing seat 9 .

[0033] like Figure 6 and Figure 7 As shown, the fixing seat 8 is provided with a first inclined surface 11, and the first inclined surface 11 is provided with a slide rail and a threaded hole 14;

[0034] The pressing seat 9 is provided with a second inclined surface 12 adapted to the first inclined surface 11, and the second inclined surface 12 is provided with a slide groove slidably matched with the slide rail, and the upper surface of the pressing seat 9 is provided with a step hole 13, and the step hole 13 (the small size end) is connected to the slide groove;

[0035] The clamping seat 9 is connected to the fixing seat 8 via bolts 15 and threaded holes 14 , and the bolts 15 enter the threaded holes 14 via the step holes 13 .

[0036] The fixing seat 8 is welded to the inner wall of the mud collecting bucket 3 .

[0037] like Figure 7 As shown, the fixing seat 8 is connected to the mud collecting bucket 3 by screws.

[0038] An inclined baffle 16 is provided in the mud collecting bucket 3 , and an installation space is formed between the baffle 16 and the inner wall of the mud collecting bucket 3 , and the motor of the screw conveyor 4 is arranged in the installation space.

[0039] The step hole 13 includes a first waist-shaped hole and a second waist-shaped hole arranged from top to bottom, the first waist-shaped hole is larger than the second waist-shaped hole, the width of the second waist-shaped hole is adapted to the screw diameter of the bolt 15, and the width of the first waist-shaped hole is adapted to the head diameter of the bolt 15.

[0040] Among them, 1. The plate-frame filter press 1 is a prior art, and its specific structure and principle are not described here. 2. The width of the clearance groove 10 is adapted to the width of the fixing seat 8 , and the width of the clearance groove 10 is smaller than the width of the pressing seat 9 .

[0041] Working principle: After the tunnel sewage enters the plate and frame filter press 1, the sludge enters the sludge collecting bucket 3 below, where the sludge is collected and then automatically cleaned to the sludge transport truck 6 through the screw conveyor 4.

[0042] A mud bucket and a screw conveying device are installed in the mud discharge and collection area below the plate and frame filter press 1 to realize automatic mud collection and cleaning.

[0043] Because automatic mud cleaning is achieved, the space of the mud collection area can be compressed from more than 3 meters to less than 1.5 meters, the overall height of the equipment is reduced, and cleaning and replacement of the filter cloth is safe and convenient.

[0044] At the same time, the screw conveyor 4 is detachably arranged in the mud collecting bucket 3 through a connecting assembly, and the overall weight of the screw conveyor 4 is borne by the mud collecting bucket 3. There is no need to worry about the screw conveyor 4 falling during use, and the screw conveyor 4 is easy to disassemble and assemble.

[0045] When installing the screw conveyor 4, the screw conveyor 4 is hoisted into the mud bucket 3 and the clearance groove 10 on the bracket 7 is aligned with the fixed seat 8, so that the fixed seat 8 enters the clearance groove 10. In this process, the fixed seat 8 cooperates with the bracket 7 to complete the positioning of the screw conveyor frame (for the convenience of installation, the clearance groove 10 is U-shaped, and the opening of the clearance groove 10 is set downward).

[0046] When the fixing seat 8 is in place, slide the slide groove of the pressing seat 9 into the slide rail, then insert the bolt 15 into the threaded hole 14 through the step hole 13, and tighten the bolt 15. When the bolt 15 is tightened, the bolt 15 presses the pressing seat 9 down until it is pressed against the bracket 7 (to ensure the pressing effect, the bracket 7 is fixed to the pressing seat 9 by two sets of symmetrically arranged fixing seats 8).

[0047] For different models of screw conveyors 4, a larger model of screw conveyor 4 is taken as an example to explain: in order to improve the strength of the bracket 7, the thickness of the bracket 7 is increased accordingly. At this time, the corresponding bolt 15 is screwed in to a reduced depth to adapt to the bracket 7 with increased thickness, thereby improving the application range of the clamping seat 9 and the fixing seat 8.

[0048] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
