DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. 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 implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0031] Example:

[0032] The utility model provides a sewage pipe capable of filtering out calcium slag. Figure 1-Figure 3 As shown, it includes a slag removal part 100, a first tube 200 and a second tube 300, wherein:

[0033] The slag removal section 100 is used to remove calcium slag in wastewater. The slag removal section 100 has an inlet and an outlet, i.e., a water inlet and a water outlet. Wastewater enters the slag removal section 100 from the water inlet, and then the calcium slag in the wastewater is intercepted in the slag removal section 100 and removed from the wastewater, and the wastewater with the calcium slag removed goes out from the outlet.

[0034] One end of the first tube 200 is connected to the source of calcium-containing wastewater, that is, the wastewater produced by the enterprise in producing lithium carbonate flows into the first tube 200, and the other end of the first tube 200 is connected to the inlet of the above-mentioned slag removal part 100. In this way, with the help of the first tube 200, the wastewater containing calcium slag is introduced into the above-mentioned slag removal part 100, and one end of the second tube 300 is connected to the pump body for pumping wastewater, and the other end of the second tube 300 is connected to the outlet of the above-mentioned slag removal part 100. When the pump body is powered on, the wastewater removed from the calcium slag in the slag removal part 100 will reach the pump body through the diversion of the second tube 300. The above-mentioned pump body can be a water pump or a sewage pump, as long as it can pump wastewater. Of course, the pump body is connected to a power supply to power the pump body, and the water outlet of the pump body can be connected to a wastewater treatment plant through a pipeline to send wastewater to the wastewater treatment plant. Optionally, the length of the above-mentioned first tube 200 is less than that of the above-mentioned second tube 300.

[0035] Through the above structure, the wastewater containing calcium slag first flows into the above-mentioned slag removal part 100 through the first pipe 200, and the slag removal part 100 intercepts the calcium slag in the wastewater therein, and then the wastewater with most of the calcium slag removed by the slag removal part 100 flows to the pump body through the second pipe 300. In this way, the calcium slag content in the wastewater flowing to the second pipe 300 and the pump body is very small, and a very small amount of calcium slag is directly discharged from the pump body under the flow of water, and is extremely difficult to adhere to the inner wall of the second pipe 300, thereby reducing the probability of calcium slag clogging the second pipe 300 and the probability of calcium slag damaging the pump body.

[0036] Based on the above structure, the sewage pipe provided by the utility model can not only transport wastewater to the pump body, but also remove most of the calcium slag in the wastewater during the transportation process to keep the wastewater transportation path unobstructed and the pump body operating normally.

[0037] An optional implementation of this embodiment is as follows: the above-mentioned slag removal part 100 intercepts the calcium slag therein through the filter screen 130 and sedimentation. Specifically, the slag removal part 100 includes a cylinder 110, an upper cover 120 and a filter screen 130, wherein:

[0038] The top of the cylinder 110 is penetrated to form a cylinder mouth, or a through hole is opened on the top of the cylinder 110, and the through hole constitutes the cylinder mouth of the cylinder 110. The upper cover 120 covers the above-mentioned cylinder mouth and seals the cylinder mouth of the cylinder 110, thereby preventing foreign impurities from falling into the cylinder 110, and also preventing waste water in the cylinder 110 from overflowing from the cylinder mouth. Of course, a sealing ring can also be installed between the upper cover 120 and the edge of the cylinder mouth of the cylinder 110 to better achieve a sealing effect.

[0039] The filter screen 130 can be a wire mesh or a mesh cloth, and the filter screen 130 is installed inside the cylinder 110. A water inlet chamber 140 is formed between the filter screen 130 and the bottom of the cylinder 110. The inlet is arranged on the side wall of the water inlet chamber 140. A water outlet chamber 150 is formed between the filter screen 130 and the cylinder cover, and the outlet is arranged on the side wall of the water outlet chamber 150. In this way, the wastewater first enters the water inlet chamber 140, and the filter screen 130 intercepts most of the calcium slag in the wastewater, and then the wastewater enters the water outlet chamber 150 and finally exits from the outlet. Of course, in order to allow the intercepted calcium slag to be smoothly settled at the bottom of the water inlet chamber 140 (that is, to be precipitated at the bottom of the cylinder 110), the pump body in this embodiment is intermittently operated, and an on-off valve is installed in the first pipe 200, and the on-off valve is also intermittently on and off, so that the wastewater in the above-mentioned slag removal part 100 can be left to stand and the calcium slag therein can be settled.

[0040] When the calcium slag settled in the cylinder 110 needs to be removed, the upper cover 120 is opened and the filter screen 130 is removed, and the calcium slag settled at the bottom of the cylinder 110 is removed with a tool, which may be a mud pump or a plastic scoop with an extension rod.

[0041] Of course, the above-mentioned slag removal part 100 can also be a centrifugal slag removal machine or a filter press.

[0042] Optionally, the filter screen 130 is installed obliquely in the cylinder 110, and the filter screen 130 is located at the upper part of the cylinder 110, and the end of the filter screen 130 close to the inlet is higher than the end close to the outlet, so that the volume of the water inlet chamber 140 is larger than the water outlet chamber 150, thereby providing a better and more spacious space for the precipitation of calcium slag.

[0043] Optionally, the position of the inlet on the cylinder 110 is lower than the outlet, so that the waste water enters low and exits high in the slag removal section 100 , which is also more conducive to the precipitation of calcium slag in the water inlet chamber 140 .

[0044] In order to more conveniently discharge the calcium slag deposited at the bottom of the water inlet chamber 140, optionally, in the present embodiment, a slag discharge pipe 400 is also connected and arranged on the lower wall of the cylinder body 110, and the slag discharge pipe 400 has a slag inlet and a slag outlet, and the slag inlet is connected to the lower part or the bottom of the water inlet chamber 140, and a sealing member 500 is also detachably installed on the slag discharge pipe 400, and the sealing member 500 is used to seal the above-mentioned slag outlet.

[0045] When slag discharge is not required, the slag outlet of the slag discharge pipe 400 is blocked by the sealing member 500, and the calcium slag settles at the bottom of the water inlet chamber 140, and part of the calcium slag also enters the slag discharge pipe 400. When slag discharge is required, the sealing member 500 is opened, and clean water is added to the cylinder 110 through the cylinder mouth of the cylinder 110 or the first pipe 200, so that the calcium slag settled at the bottom of the cylinder is flushed out from the slag discharge pipe 400, and the flushed calcium slag is collected by a bucket or other container.

[0046] Optionally, the sealing member 500 may be a ball valve, so as to more conveniently control the opening and closing of the slag outlet of the slag discharge pipe 400. Of course, the sealing member 500 may also be a cover screwed on the slag outlet of the slag discharge pipe 400.

[0047] In order to facilitate the staff to check the specific situation in the above-mentioned cylinder 110 at any time, in this embodiment, a window is opened in the above-mentioned upper cover 120, and a transparent glass plate 121 is installed in the window. Of course, a transparent plastic plate can also be used instead of the above-mentioned transparent glass plate 121. The transparent glass plate 121 blocks the above-mentioned window. Through the above-mentioned transparent glass plate 121, the staff can clearly see the specific situation in the above-mentioned cylinder 110.

[0048] In order to facilitate the disassembly and assembly of the upper cover 120, an optional implementation of this embodiment is that a first ring 600 is provided on the outer edge of the upper cover 120, a first through hole 610 is opened in the first ring 600, a second ring 700 is provided on the outer wall at the mouth of the cylinder 110, a second through hole 710 corresponding to the first through hole 610 is opened in the second ring 700, and a bolt 800 and a nut 900 are also included. The bolt 800 passes through the first through hole 610 and the second through hole 710 and is screwed with the nut 900. In this embodiment, the first ring 600 and the upper cover 120 are integrally formed, and the second ring 700 and the cylinder 110 are integrally formed.

[0049] With the cooperation of the bolts 800 and the nuts 900 , the upper cover 120 is stably mounted on the barrel mouth and is convenient for assembly and disassembly.

[0050] Of course, the upper cover 120 may also be connected to the mouth of the cylinder 110 by screwing.

[0051] In order to make the upper cover 120 more firmly installed at the mouth of the cylinder 110, in this embodiment, the number of the first through holes 610 and the second through holes 710 is multiple, and the multiple first through holes 610 and the multiple second through holes 710 correspond to each other to form multiple groups of holes, and the multiple groups of holes are evenly distributed around the cylinder 110. Each group of holes is installed with a bolt 800, and each bolt 800 is screwed with a nut 900. Specifically, the number of the first through holes 610 and the second through holes 710 is four, six, or eight.

[0052] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
