[0026] The technical scheme of the present invention is further elaborated in detail below in conjunction with specific embodiments. The parts of the present invention that are not described and disclosed in detail in the following embodiments should be understood as the prior art known or should be known to those skilled in the art, such as the specific structure of the coal mine water purification system 12, the model and specific structure of the one-way valve 802, the model of the heating tube 10 and how to heat it, the model of the pH detector 11, the models of the outlet pipe 1201 and the inlet pipe 1202, the model of the circulating pump 13, how to prepare the cleaning liquid, etc.

[0027] Example 1

[0028] A pipe cleaning device for a coal mine water purification system, such as Figure 1-Figure 4 As shown, it includes: a supply box 1 for storing cleaning liquid, the supply box 1 transports the cleaning liquid to the coal mine purification water system 12 through a circulation pump 13, and the cleaning liquid is transported to the coal mine purification water system 12 through a water inlet pipe 1202 to descale the pipeline of the coal mine purification water system 12. When descaling the coal mine purification water system 12, the acidity of the cleaning liquid will gradually decrease. Therefore, a storage box 8 for replenishing the cleaning liquid to the supply box 1 is provided above the supply box 1. After the cleaning liquid flows out from the outlet pipe 1201 of the coal mine purification water system 12, a lot of scale has been mixed in the cleaning liquid. If it continues to circulate into the coal mine purification water system 12, it will interfere with the descaling effect of the cleaning liquid. Therefore, a filtering and recycling mechanism is provided on the upper part of the supply box 1, and the filtering and recycling mechanism includes a liquid dispersion plate 6 and a filter screen 3 distributed up and down, and there is a gap between the liquid dispersion plate 6 and the filter screen 3, and the liquid dispersion plate 6 is located below the storage box 8. The cleaning liquid flows out through the outlet pipe 1201 and enters the supply box 1 through the filter 3. At this time, the filter 3 will filter out the agglomerated scale in the cleaning liquid. At this time, the cleaning liquid in the storage box 8 flows to the filter 3 along the liquid dispersion plate 6. The cleaning liquid can further rinse the agglomerated scale on the filter 3 to reduce the scale on the filter 3. At the same time, the cleaning liquid flowing out of the outlet pipe 1201 can also rinse the scale on the filter 3 to reduce the scale on the filter 3. Under the action of these two methods, the scale on the filter 3 becomes less and less, and the agglomerated scale entering the cleaning liquid becomes less and less, and it is not easy to clog the pipeline; and the cleaning liquid flowing out of the storage box 8 is dispersed by the liquid dispersion plate 6, and enters the supply box 1 through the filter 3, thereby increasing the acidity of the cleaning liquid in the supply box 1 and further improving the scale removal effect.

[0029] The above is a basic implementation of the present invention, and further improvements, optimizations and limitations can be made on the above basis to obtain the following embodiments:

[0030] Example 2

[0031] This embodiment is an improved solution based on the embodiment 1, and its main structure is the same as that of the embodiment 1, and the improvement is that: in order to better allow the cleaning liquid in the storage box 8 to flow to the liquid dispersion plate 6, the liquid dispersion plate 6 disperses the cleaning liquid so that a larger area of ​​scale on the filter 3 can be contacted by the cleaning liquid, the liquid dispersion plate 6 is connected to the supply box 1 through the inclined guide plate 602. The guide plate 602 is provided with a guide groove 6021, and the cleaning liquid flows better to the liquid dispersion plate 6 along the guide groove 6021, and the width of the guide groove 6021 gradually decreases along the flow direction of the cleaning liquid, so that the cleaning liquid can have a greater impact effect; the width of the guide groove 6021 can also be gradually increased along the flow direction of the cleaning liquid, so that the cleaning liquid has a larger diffusion area when flowing down along the guide groove 6021.

[0032] Example 3

[0033] This embodiment is an improvement on the embodiment 2, and its main structure is the same as that of the embodiment 2, with the improvement being that in order to realize the detachable connection between the guide plate 602 and the supply box 1, a mounting strip 7 is fixedly connected to the guide plate 602, and the mounting strip 7 is connected to the box wall of the supply box 1 through a plurality of mounting bolts 702, and a plurality of countersunk holes 701 for accommodating the heads of the mounting bolts 702 are provided on the mounting strip 7 to prevent the cleaning liquid from directly contacting the mounting bolts 702 and causing the mounting bolts 702 to loosen.

[0034] Example 4

[0035] This embodiment is an improved solution based on the embodiment 1, and its main structure is the same as that of the embodiment 1, and the improvement lies in that: the bottom of the storage box 8 is provided with an opening, and the opening is connected with a mounting pipe 801, and a one-way valve 802 is fixedly arranged inside the mounting pipe 801. Since the storage box 8 also stores cleaning liquid, the overall weight is relatively large, and a bearing block 804 for carrying the storage box 8 is fixedly arranged on the mounting bar 7, and a receiving groove is provided on the bearing block 804, and a plug 803 is fixedly arranged in the receiving groove, and the plug 803 can be inserted into the one-way valve 802, and a liquid outlet channel 805 connected with the plug 803 is provided at the bottom of the receiving groove. When the plug 803 is inserted into the one-way valve 802, the cleaning liquid in the storage box 8 will flow out, flow out of the liquid outlet channel 805 through the plug 803, and then flow to the filter 3 through the liquid dispersion plate 6. When the cleaning liquid in the storage liquid needs to be replenished, the storage box 8 is lifted, and the cannula 803 leaves the one-way valve 802, and the remaining cleaning liquid in the storage box 8 will not flow out, which will harm the health of the operator. The pipeline cleaning device includes a controller, and a PH detector 11 for detecting the PH value of the cleaning liquid is connected to the supply box 1, and the circulation pump 13 and the PH detector 11 are both connected to the controller. The PH detector 11 detects the PH value of the cleaning liquid. In order to automatically replenish the cleaning liquid as needed, a valve can be set at the liquid outlet channel 805. The valve is connected to the controller, and the valve is controlled to be open according to the detection of the PH value.

[0036] Example 5

[0037] This embodiment is an improved solution based on the embodiment 1, and its main structure is the same as the embodiment 1, and the improvement is that: in order to make the cleaning liquid flowing onto the liquid dispersion plate 6 more uniform, a plurality of through holes 601 for the cleaning liquid to pass through are provided on the liquid dispersion plate 6, and the inner diameter of the through hole 601 gradually increases along the flow direction of the cleaning liquid. As the cleaning liquid gradually flows forward, the impact of the cleaning liquid gradually weakens. Therefore, in order to ensure that the cleaning liquid can flow forward more, the inner diameter of the through hole 601 gradually increases along the flow direction of the cleaning liquid, so that the cleaning liquid first flows through the through hole 601 with a small aperture to the filter screen 3 and contacts the scale, and the remaining cleaning liquid continues to flow forward.

[0038] Example 6

The cleaning liquid flowing out of the coal mine purification water system 12 through the outlet pipe 1201 will first flow to the mounting plate 2, and flow along the mounting plate 2 to the filter screen 3. In order to prevent the water from being flushed out of the filter screen 3 due to excessive flow, and the scale in this part of the cleaning liquid is not filtered, therefore, a baffle 4 will be provided on the frame, and all the scale will be gathered in the scale collection area 14.

[0040] In order to enable the filter 3 to be detachably connected to the supply box 1, the mounting plate 2 and the supply box 1 are clamped together by a clamping plate 5, and the clamping plate 5 includes an extension portion 501 and a restriction portion 502 that are fixedly connected, and the extension portion 501 and the restriction portion 502 are perpendicular to each other, and the extension portion 501 and the mounting plate 2 are fixedly connected, and the side wall of the supply box 1 can contact the surface of the extension portion 501 and the restriction portion 502.
