[0022] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely descriptive and not restrictive, and the protection scope of the present invention cannot be limited by them.

[0023] A split type water quality monitoring automatic dosing device, as shown in the figure, includes a square platform 1, a rectangular platform 13 and a staircase 19. Two spaced running wheels 27 are provided on any of the two symmetrical sides of the bottom of the square platform, the rectangular platform and the staircase, and the two running wheels on both sides are arranged in alignment with each other. The square platform, the rectangular platform and the staircase are provided with a fixing mechanism for connecting with each other. Among the above-mentioned running wheels, the two running wheels in the middle of the two sides can use universal wheels, the main purpose of which is to ensure that they can turn when dragging, for example: Figure 3-5 Among them, the two traveling wheels on the front and rear sides on the right are universal wheels.

[0024] The square platform is used to set a medicine tank 4, and a flap-type liquid level meter 8 is installed on the side of the medicine tank. In addition to displaying the liquid level, the flap-type liquid level meter can also send the liquid level detection data by electronic signals. The bottom of the medicine tank is fixed by a screw connection method of a column and a bolt, or by a welding method of a column and welding. The detachable screw connection method of the former is preferred, so that medicine tanks of different volumes can be replaced under the premise of ensuring overall stability, such as: using a short and fat medicine tank with a larger diameter and a shorter height or using a tall and thin medicine tank with a smaller diameter and a higher height. If the height of the medicine tank is high, the lower end of the medicine tank can be sunk to the inside of the square platform, so as to avoid the risk of easy dumping caused by too high a center of gravity. The medicine tank has a dosing port 6 and a drug outlet 7. In addition to the dosing port, an infusion tube 24 and an agitator 5 can also be set on the medicine tank so that the medicine tank can adapt to a variety of dosing methods. The round cover of the dosing port is well sealed, and an electric control valve or a manual valve can be installed on the flange of the infusion tube.

[0025] The rectangular platform is used to set up a control cabinet 17 and at least one metering pump 14, 16. Figure 1-2In the figure, one metering pump 14 is mainly used, and the other metering pump 16 is a standby. The inlet 12 and the inlet 18 of the two metering pumps are respectively connected in series with a valve, and then the two valves are connected in parallel with the connector 11 through a tee. The connector can be connected to the outlets of different medicine tanks through pipelines, valves, etc. By opening and closing the valve of the inlet, it is possible to control which metering pump is used for the output of the liquid medicine. The outlets of the two metering pumps are connected to the output pipeline 15, and the output pipeline is connected to any tank body through pipelines, valves, etc.

[0026] The control cabinet has terminals for connecting various devices. Necessary electrical equipment for automatic or manual control, such as inverters, transformers, relays, PLCs, switches, display instruments, buttons, etc., can be placed inside the control cabinet. These electrical equipment should be connected with cables in advance, and the cables should be connected to the terminals on the cable rack at the front of the cabinet. When using, just connect the terminals and external devices directly. Of course, the control cabinet needs to be waterproof to avoid short circuit failure.

[0027] The upper end surface of the staircase is in the shape of a step, which can be used for staff to go up or down the stairs. In order to cooperate with the staircase, a walkway platform 21 can be set. The size of the walkway platform is the same as that of the rectangular platform, and its bottom is also provided with walking wheels and universal wheels like the rectangular platform.

[0028] The structures of square platforms, rectangular platforms and walkway platforms are as follows: Figure 3-4 As shown, they are composed of a frame 26 at the bottom and a platform above, which are vertically stacked. The two can be fixed to each other by welding or screwing. Walking wheels and universal wheels are installed inside the lower end of the frame. The stair platform is slightly different. It has stepped steps installed on the bottom frame. Each edge of the upper end surface of the walkway platform is provided with multiple openings for inserting guardrails, such as Figure 1 As shown, the plurality of transverse openings 23 can be inserted into the

[0029] The long guardrail 22 has multiple vertical openings for inserting the shorter guardrail 25. Two types of guardrails can be installed according to the specific location and protection requirements of the aisle. The staircase is provided with multiple openings on both sides of the steps, and the inclined guardrail 20 can be inserted into the multiple openings on each side. The specific side or both sides to be inserted also needs to be determined according to the use position.

[0030] In terms of size, the length of the long side of the rectangular platform is the same as the length of the side of the square platform, and the width of the short side of the rectangular platform is half the length of the side of the square platform; the side lengths of the staircase platform are half the length of the side of the square platform; the length of the long side of the walkway platform is the same as the length of the side of the square platform, and the width of the short side of the walkway platform is half the length of the side of the square platform.

[0031] Square platforms, rectangular platforms, walkway platforms and stair platforms all require a fixing mechanism when used in combination. The specific structure is:

[0032] The fixing mechanism of the square platform includes a groove 3 and a threaded hole 2. Two mutually spaced grooves are respectively arranged on the four sides of the upper end surface of the square platform. Each groove has an opening 28 formed on the side close to the same side edge of the square platform, and a vertical threaded hole is arranged on the bottom surface of the groove. The fixing mechanism of the rectangular platform includes a groove and a threaded hole. Two mutually spaced grooves are respectively arranged on the four sides of the upper end surface of the rectangular platform. Each groove has an opening formed on the side close to the same side edge of the rectangular platform, and a vertical threaded hole is arranged on the bottom surface of the groove. Two mutually spaced grooves are respectively arranged on the four sides of the upper end surface of the walkway platform. Each groove has an opening formed on the side close to the same side edge of the walkway platform, and a vertical threaded hole is arranged on the bottom surface of the groove. The fixing mechanism of the staircase platform includes a groove and a threaded hole. Two mutually spaced grooves are arranged on the highest step of the staircase platform. The two grooves have openings formed on the side close to the same side edge of the staircase platform, and a vertical threaded hole is arranged on the bottom surface of the groove.

[0033] The fixing mechanism also includes a connecting plate, which can be placed in the mutually aligned grooves of the square platform, the long hair platform, the walkway platform and the staircase platform after they are aligned with each other. The bolts 10 installed in the openings at both ends of the connecting plate can be screwed into the threaded holes aligned with the openings, so that the connecting plate connects the grooves on both sides together.

[0034] Select the site, level the land, and measure the dimensions. Figure 1 The dosing equipment of the structure uses two square platforms, one rectangular platform, two walkway platforms and one staircase platform. The ports, pipes, electrical equipment, etc. of the equipment on each platform are not connected. First, all the platforms are transported to the site by trailer. According to the structure in the figure, different platforms are dragged by forklift, pushed manually or lifted by crane to the place, and the connecting plates are installed with bolts to combine the platforms together. In order to improve the overall stability, metal rods can also be inserted into the fixing holes made in the bottom frame of each platform, and then the metal rods can be hammered into the ground for further fixing, or long bolts can be used to screw them below the ground.

[0035] The combined structure is shown in the figure. Two square platforms and one rectangular platform constitute the upper row in the figure, while two walkways and staircases with guardrails inserted in different positions constitute the lower row in the figure. The staff goes upstairs through the staircase, then installs the pipelines and / or valves of various interfaces, pipes, flanges, etc., connects them to the final dosing tank body, connects the cables of the electronic equipment to the wiring terminals of the control cabinet, and then connects the necessary external input pipelines, external power supplies, lighting and other equipment before dosing and testing.

[0037] In the utility model, a medicine tank is installed on the square platform, a control cabinet and at least one metering pump are installed on the rectangular platform, and the staircase and walkway can be walked on or up and down. The square platform, rectangular platform, staircase and walkway adopt a modular structure. When assembling each module, a connecting plate can be embedded in the grooves on the adjacent sides, and then the connecting plate is fixed in the groove by two bolts, thereby fixing the adjacent modules together. Different modules can be combined according to the site shape of the sewage treatment plant. If the area is large enough, a walkway can be added to allow the staff to inspect or repair each device more safely. If the area is small, the square platform and rectangular platform can also be used to inspect or repair each device. Through the above modular combination method, a more flexible equipment installation method is provided when the sewage treatment plant is upgraded and renovated, and after no longer in use, the whole can be separated and dragged or lifted away separately.
