DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0023] The embodiment of the present application provides an underground brine sedimentation tank, which can solve the problem of impurities accumulated on the side walls and bottom of the brine sedimentation tank in the related art, which is mainly handled by manual cleaning, which requires a lot of time and manpower and has the problem of incomplete cleaning.

[0024] See also Figure 1-Figure 3 An underground brine sedimentation tank comprises: a sedimentation tank 1 having a chamber 2 for brine sedimentation therein; a scraping mechanism 3 for cleaning the chamber 2 is arranged on the sedimentation tank 1, and the scraping mechanism 3 comprises a driving member 31, a scraper plate 32, a linear slide rail 33 and a pair of scrapers 34, wherein the driving member 31 is arranged on the sedimentation tank 1, the scraper plate 32 is slidably arranged inside the chamber 2 and is used to scrape impurities on both sides and at the bottom of the chamber 2, the driving member 31 is connected to the scraper plate 32 and is used to drive the scraper plate 32 to move along the length direction of the chamber 2; a pair of scrapers 34 are relatively slidably arranged on both sides of the scraper plate 32 and are used to scrape impurities at both ends of the chamber 2, and the linear slide rail 33 is connected to the scraper 34 and is used to drive the scraper 34 to move along the width direction of the chamber 2.

[0025] In actual operation, the brine is first introduced into the chamber 2 of the sedimentation tank 1. In the chamber 2, the brine gradually settles due to gravity, and the suspended particles and insoluble substances therein gradually settle to the bottom of the chamber 2. After a period of sedimentation, most of the impurities in the brine are removed, forming relatively clear brine.

[0026] After a period of use, when a large amount of impurities are attached to the bottom and side walls of the sedimentation tank 1, the driving member 31 is turned on, and the driving member 31 drives the scraper 32 to move along the length direction of the chamber 2. Driven by the driving member 31, the scraper 32 scrapes off the impurities attached to the bottom and both sides of the chamber 2, and the scraped impurities are pushed to one end of the chamber 2 as the scraper 32 moves.

[0027] Furthermore, in order to improve the scraping effect, the linear slide rail 33 is repeatedly opened at the starting and end positions of the scraper blade 32. The scraper 34 is driven by the linear slide rail 33 to move along the width of the chamber 2, thereby being able to scrape the side walls at both ends of the chamber 2 to ensure the cleanliness of the interior of the chamber 2.

[0028] Through this automatic cleaning mechanism, the sedimentation tank 1 can maintain a high-efficiency sedimentation effect for a long time, avoiding the problem of reduced sedimentation efficiency due to impurity accumulation. Through the automated cleaning process, the labor intensity of workers is greatly reduced, production costs are reduced, and cleaning efficiency is improved. In addition, this method can completely scrape away impurities in the chamber 2 without leaving dead corners, ensuring the cleanliness of the sedimentation tank 1, avoiding possible safety risks in the manual cleaning process, and ensuring the safety of workers.

[0029] It should be noted that the scraper blade 32 in this embodiment is rectangular, and the two ends and the bottom of the scraper blade 32 are respectively in contact with the two sides and the bottom of the chamber 2, and the length and width of the scraper blade 32 are respectively adapted to the length and width of the chamber 2.

[0030] The design of the scraper 32 fully considers the shape and size of the chamber 2 of the sedimentation tank 1 to ensure that it can effectively scrape away impurities in the chamber.

[0031] Specifically, the scraper blade 32 is designed to be rectangular, so that the scraper blade 32 can move stably in the chamber 2. The two ends of the scraper blade 32 fit with the two sides of the chamber 2, so as to scrape off impurities attached to the side walls; and its bottom fits with the bottom of the chamber 2, so as to scrape off impurities deposited on the bottom.

[0032] In addition, the length and width of the scraper blade 32 are respectively adapted to the length and width of the chamber 2, ensuring that the scraper blade 32 can cover the entire bottom and side wall of the chamber 2 without leaving any dead corners. When the driving member 31 drives the scraper blade 32 to move along the length direction of the chamber 2, the scraper blade 32 can completely and efficiently scrape away impurities in the chamber.

[0033] Specifically, Figure 2 and Figure 4As shown, in this embodiment, the driving member 31 includes a group of shells 311, a group of driving motors 312 and a group of racks 313. One group of the shells 311 is relatively arranged on the sedimentation tank 1, and one group of the driving motors 312 is relatively arranged on the scraper 32. The rack 313 is arranged inside the shell 311, and the output shaft of the driving motor 312 is provided with a gear 314 meshing with the rack 313.

[0034] In actual operation, the shell 311 is set on the sedimentation tank 1 as the fixed part of the mechanism. Through the rotation of the drive motor 312, the gear 314 on its output shaft will engage with the rack 313, so that through the interaction between the gear 314 and the rack 313, the rotational motion of the drive motor 312 is converted into the linear motion of the scraper 32, thereby driving the scraper 32 to move along the length of the chamber 2.

[0035] It can be understood that a groove is provided at one end of the housing 311 close to the scraper blade 32 , and the rack 313 is provided above the groove.

[0036] In this embodiment, a waterproof housing is provided outside the driving motor 312 .

[0037] The linear guide rail 33 in this embodiment is also called a linear guide rail, a linear guide rail or a linear slide rail, and is mainly used in high-precision or fast linear reciprocating motion places, and can bear a certain torque to complete high-precision uniform linear motion. This moving part is mainly composed of a guide rail, a slider and a ball or a contact surface between the sliders, and its working principle can be based on rolling friction or sliding friction, which is a prior art and will not be repeated here.

[0038] It can be understood that the scraping mechanism 3 in this embodiment is made of a corrosion-resistant and wear-resistant material to meet the special requirements of the brine environment.

[0039] Preferably, Figure 3 As shown, the present embodiment also includes a blocking net 4, which is arranged in the middle of the scraper 32 and is used to collect impurities floating on the surface of the brine in the chamber 2.

[0040] The blocking net 4 is placed in the middle of the scraper 32, and its main function is to collect impurities floating on the surface of the brine in the chamber 2. When the scraper 32 moves along the length direction of the chamber 2 under the drive of the driving member 31, the blocking net 4 will also move with it, scraping and collecting the floating impurities from the surface of the brine.

[0041] The design of the barrier net 4 can be adjusted according to the characteristics of the brine and the size of the impurities to ensure that it can effectively intercept the floating impurities. At the same time, the material of the barrier net 4 also needs to consider corrosion resistance to adapt to the special requirements of the brine environment.

[0042] In this embodiment, a liquid inlet pipe 5 is provided on the sedimentation tank 1 , and the liquid inlet pipe 5 is used to deliver external brine into the chamber 2 .

[0043] An important component of the sedimentation tank 1 is the liquid inlet pipe 5 , which is arranged on the sedimentation tank 1 , and its main function is to allow external brine to flow smoothly into the chamber 2 .

[0044] In this embodiment, a conveying mechanism 6 is provided on the sedimentation tank 1, and the conveying mechanism 6 includes a pump body and a discharge pipe. The liquid inlet of the pump body is connected to the chamber 2, and the liquid outlet of the pump body is connected to the discharge pipe and is used to deliver the precipitated brine to the next treatment tank.

[0045] A conveying mechanism 6 is provided on the sedimentation tank 1, and its main function is to efficiently and stably convey the brine after sedimentation to the next treatment tank to ensure the continuity and efficiency of brine treatment.

[0046] When the pump body is started, it can directly extract the brine that has been precipitated from the chamber 2, and the liquid outlet of the pump body is connected to the drainage pipe, which transports the brine extracted by the pump body to the next treatment tank.

[0047] It is understandable that the material of the drain pipe is corrosion-resistant and wear-resistant material to meet the special requirements of the brine environment.

[0048] Further, such as Figure 2 As shown, the present embodiment also includes a sludge discharge mechanism 7, which includes a delivery pipe and a sludge pump. The liquid inlet of the sludge pump is connected to the chamber 2, and the liquid outlet of the sludge pump is connected to the delivery pipe and is used to pump out the sludge deposited inside the chamber 2.

[0049] When the sludge pump is started, the sludge deposited at the bottom of the chamber 2 is extracted, and the liquid outlet of the sludge pump is connected to the delivery pipe, and the extracted sludge is delivered to the designated discharge location or treatment equipment through the delivery pipe.

[0050] By setting the silt removal mechanism 7, the underground brine sedimentation tank 1 can remove the silt in the chamber regularly or in time according to the silt accumulation situation. This not only helps to keep the inside of the sedimentation tank clean and improve the sedimentation effect of brine, but also can extend the service life of the sedimentation tank and reduce the maintenance cost caused by silt accumulation.
