Description

Technical Field

[0001] This utility model relates to the field of brine treatment technology, and in particular to a brine pretreatment device. Background Technology

[0002] In well salt production, brine containing salt is typically extracted from underground using drilling technology. The brine then undergoes purification, concentration, crystallization, and separation processes to extract salt crystals, which are then dried and packaged, thus completing the production and processing of well salt. During the brine purification process, pretreatment devices are usually used to filter the brine and remove impurities, facilitating subsequent brine processing.

[0003] A Chinese patent, such as CN220495748U, discloses a brine pretreatment device. This device uses a filter cover to filter impurities in the brine initially, and a drawer-type filter assembly to filter impurities a second time. This dual filtration provides good brine filtration. A cleaning mechanism is also included; a rotary motor on the cleaning mechanism drives a cleaning brush to rotate, cleaning the surface of the first filter screen on the filter cover and preventing clogging of the filter holes, which would hinder brine filtration. However, during the cleaning process, impurities accumulate on both the cleaning brush and the first filter screen, resulting in poor cleaning and clogging of the first filter screen. This ultimately affects its normal use and hinders brine filtration. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5As shown, a brine pretreatment device includes a pretreatment tank 1. The top of the pretreatment tank 1 is connected to a water inlet pipe 2, and the bottom is connected to a water outlet 10. The pretreatment tank 1 is equipped with a first filter element and a drawer-type filter assembly 9. The pretreatment tank 1 is also equipped with a cleaning brush assembly and a suction assembly for cleaning the first filter element. The first filter element includes a filter frame 15 installed inside the pretreatment tank 1. The filter frame 15 has a V-shaped structure, and filter screens 16 are embedded on both sides of the inner wall of the filter frame 15. The structure and principle of the drawer-type filter assembly 9 are existing technologies. For details, please refer to the prior art (authorization announcement number: CN220495748U, title: A brine pretreatment device), which will not be described in detail here.

[0023] It also includes a spray structure for rinsing the first filter element. The spray structure includes a spray ring 14 installed at the top inside the pretreatment tank 1, a spray plate 18 fixed on both sides of the inner wall of the pretreatment tank 1, and a liquid supply component provided on one side of the pretreatment tank 1. The bottom of the spray ring 14 is equipped with uniformly distributed first nozzles, and the liquid outlet end of the first nozzle faces the top of the first filter element. The top of the spray plate 18 is equipped with uniformly distributed second nozzles, and the liquid outlet end of the second nozzle faces the bottom of the first filter element.

[0024] Specifically, the liquid supply component includes a support frame installed on one side of the pretreatment tank 1, a liquid storage tank 7 and a pump body 8 installed on the support frame. One end of the pump body 8 is connected to the liquid storage tank 7 via a water pumping pipe, and the other end is connected to a liquid delivery pipe 6. One end of the liquid delivery pipe 6 is equipped with a three-way connector 5. The other two ends of the three-way connector 5 are respectively connected to a first branch pipe 4 and a second branch pipe 19. One end of the first branch pipe 4 is connected to a spray ring 14. One side of the second branch pipe 19 is connected to a third branch pipe 20. One end of the second branch pipe 19 and the third branch pipe 20 are respectively connected to two spray plates 18. The liquid storage tank 7 is provided with a water inlet for easy water filling.

[0025] As described above, during the pretreatment of brine, brine can be added into the pretreatment tank 1 through the inlet pipe 2. At this time, the brine first falls onto the filter rack 15 and is filtered by the filter screen 16. After filtration, impurities are blocked in the filter rack 15, while the brine flows down through the filter screen 16 and falls into the drawer-type filter assembly 9. At this time, the filter assembly 9 filters the brine again. After filtration, the brine flows to the bottom of the pretreatment tank 1 and is then discharged through the outlet 10. This achieves multi-stage filtration of the brine, thereby completing the pretreatment of the brine and facilitating subsequent processing of the brine.

[0026] After the device processes the brine, the filter screen 16 on the filter rack 15 can be cleaned by the cleaning component to prevent the filter screen 16 from clogging. Furthermore, the impurities on the filter rack 15 can be sucked out by the suction component to further prevent the filter screen 16 from clogging, which is conducive to the efficient filtration of the brine by the filter screen 16.

[0027] Meanwhile, after the brine is treated, the water in the storage tank 7 can be pumped out by the pump body 8, and then transported into the first branch pipe 4 and the second branch pipe 19 through the liquid delivery pipe 6 and the three-way connector 5. Then, the first branch pipe 4 transports the water into the spray ring 14 and sprays it onto the top of the filter screen 16 through the first nozzle. Meanwhile, some of the water in the second branch pipe 19 flows into the third branch pipe 20, and then the water is sent into the two spray plates 18 and sprayed onto the bottom of the filter screen 16 through the second nozzle, so as to simultaneously flush the top and bottom of the filter screen 16, thereby achieving a comprehensive flush of the filter screen 16, avoiding dead corners when cleaning the filter screen 16, and with the help of the cleaning components, the cleaning effect of the filter screen 16 can be greatly improved, which is conducive to the efficient cleaning of the filter screen 16 and facilitates the filtration treatment of brine.

[0028] Specifically, regarding the aforementioned cleaning components, such as Figures 1-4 As shown, the cleaning assembly includes a motor 3 fixed to the top of the pretreatment box 1 and a drive shaft rotatably installed inside the top of the pretreatment box 1. A cleaning plate 17 for cleaning the filter screen 16 is installed on the drive shaft.

[0029] When cleaning the filter screen 16 on the filter frame 15, the drive shaft can be driven to rotate by the motor 3. Then the drive shaft drives the cleaning brush plate 17 to rotate, so that the cleaning brush plate 17 rotates along the inner wall of the filter frame 15 to clean the filter screen 16, avoid clogging of the filter screen 16, and help ensure the filtration of brine by the filter screen 16.

[0030] In addition, regarding the aforementioned suction components, such as Figures 1-5 As shown, the sludge suction assembly includes a sludge suction pump 11 installed on one side of the pretreatment tank 1 and a sludge collection hopper 22 set at the bottom of the filter frame 15. One end of the sludge suction pump 11 is connected to a sewage discharge pipe 12, and the other end is connected to the sludge collection hopper 22 via a sludge suction pipe 13. The bottom end of the drive shaft extends into the sludge collection hopper 22 and is fitted with an auger 21.

[0031] When the impurities accumulated in the filter frame 15 are sucked out, the impurities flowing into the sludge collection hopper 22 are drawn out by the sludge pump 11 and the sludge collection pipe 13, and then discharged through the drain pipe 12. As the impurities in the sludge collection hopper 22 are sucked out, the impurities accumulated in the filter frame 15 will continuously flow into the sludge collection hopper 22, thereby achieving the purpose of sucking out the impurities in the filter frame 15, thus avoiding the filter frame 15 from becoming blocked, ensuring the subsequent use of the filter frame 15, and facilitating the filtration treatment of brine by the filter frame 15.

[0032] Furthermore, in order to facilitate the rapid discharge of impurities from inside the sludge collection hopper 22 and prevent impurities from remaining inside the sludge collection hopper 22, such as... Figure 2 and Figure 5As shown, two symmetrically distributed first guide blocks are also provided at the bottom of the sludge collection hopper 22, so that the bottom of the sludge collection hopper 22 forms a funnel shape.

[0033] Furthermore, to facilitate the rapid discharge of brine and prevent brine residue from remaining in pretreatment tank 1, such as... Figure 2 As shown, two symmetrically distributed second guide blocks are also provided at the bottom of the pretreatment box 1, so that the bottom of the pretreatment box 1 forms a funnel shape.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
