Description

Technical Field

[0001] This utility model relates to a curtain grouting sewage treatment device, belonging to the field of sewage treatment technology. Background Technology

[0002] Curtain grouting is a grouting project that involves injecting grout into the fissures and pores of rock or soil layers to form a continuous water-blocking curtain, thereby reducing seepage flow and lowering seepage pressure. Its main function is to prevent or reduce the seepage of groundwater in the foundation and ensure the safe operation of hydraulic structures. However, curtain grouting generates a large amount of wastewater, and the discharge of wastewater can pollute the natural environment, thus requiring wastewater purification treatment.

[0003] The existing patent number CN215480360U describes a curtain grouting wastewater treatment device. This device uses multiple treatment tanks to perform solid-liquid separation and purification of wastewater. However, the volume of each tank is limited, making it impossible to continuously purify large amounts of wastewater. Furthermore, the operation process is complex, which is not conducive to efficient wastewater treatment. The wastewater treatment additives are added directly, making it impossible to accurately control the required dosage, which can lead to incomplete wastewater treatment or waste due to excessive dosage. In addition, the device's method for treating flocculated wastewater mainly involves squeezing and dewatering the wastewater, internal particles, and flocs. The treated water is then discharged, but the solid residue inside is temporarily stored on the top of the dewatering plate. To remove the solid residue, all equipment must be shut down, which affects the wastewater treatment efficiency. Repeatedly opening and closing the tanks also increases the labor intensity and work efficiency of the staff. Utility Model Content

A support ball is rotatably connected to the lower outer side of the rotating inner box, and the support ball is in rolling connection with the outer processing box. The interior of the rotating inner box is provided with processing slots, and the number of processing slots is four.

[0008] Furthermore, a first motor is fixedly connected to the middle position of the upper plate of the support frame, and a transmission gear is fixedly connected to the upper end of the output shaft of the first motor.

A water inlet groove is opened on the inner side of the guide wheel, and a liquid inlet pipe is sealed to the upper front end of the pretreatment box. A bifurcated pipe is sealed to the left front end of the pretreatment box, and the bifurcated pipe is sealed to the liquid inlet pipe.

[0010] Furthermore, the inside of the guide box is rotatably connected to a drug feeding wheel, and the front end of the guide box is fixedly connected to a third motor, the output shaft of the third motor being fixedly connected to the drug feeding wheel.

[0011] Furthermore, a second stepper motor is fixedly connected to the middle position of the upper end of the separation box, and the output shaft of the second stepper motor is fixedly connected to the rotating circular frame.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a guide wheel to guide wastewater, and a coarse filter at the front end to filter particles such as grinding wheels. The rotation of the guide wheel allows the filtered coarse particles to be discharged through a slag discharge frame. The coarsely filtered wastewater then enters the treatment tank at the rear of the rotating inner chamber through the inlet pipe and branch pipe. The rotating inner chamber is then driven by a first-step motor, and during this rotation, a measured amount of chemicals, flocculants, and coagulants are added to the wastewater treatment tank via the rotation of the chemical feeding wheel. Combined with the rotation of the mixing blades and side wall scrapers, the chemicals, flocculants, and coagulants are thoroughly mixed with the wastewater. This allows the device to continuously treat wastewater and avoids the problem of poor wastewater treatment results caused by inaccurate control of the chemical dosage.

[0015] This invention introduces a system where, after the purified and flocculated wastewater is guided into the separation tank through a guide pipe, the wastewater first enters the lower filter screen for solid-liquid separation. The second stepper motor rotates the filter screen forward. Once the filter screen is at the lower end of the dewatering pressure plate, the hydraulic cylinder is activated, causing the dewatering pressure plate to press down, effectively dewatering the solids. After the dewatering pressure plate rises, the filter screen is rotated to the right end of the separation tank. Driven by an electric push rod and a pusher plate, the filter screen and the dewatered residue inside are removed. This allows the device to quickly separate solids and liquids and remove residues without affecting the continuous operation of the overall equipment, further improving wastewater treatment efficiency.

[0031] Please refer to Example 2 Figure 1 , Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that: the lower right end of the guide pipe 11 is sealed with a separation box 12, the separation box 12 is fixedly connected to the base 1, the upper inside of the separation box 12 is rotatably connected with a rotating circular frame 13, the inner side of the rotating circular frame 13 is provided with a filter screen 14, the filter screen 14 can receive the flocculated sewage and perform solid-liquid separation through the function of the filter screen 14, and the filter screen 14 can rotate with the rotating circular frame 13 after it is driven to rotate, so as to realize the continuous solid-liquid separation treatment of a large amount of flocculated sewage. The lower front end of the separation box 12 is sealed with a drain pipe 15, and the water after solid-liquid separation can be discharged through the drain pipe 15.

[0032] A second stepper motor 29 is fixedly connected to the middle position of the upper end of the separation box 12.

The rotation of the second stepper motor 29 can drive the rotating frame 13 to rotate at a precise angle. A hydraulic cylinder 30 is fixedly connected to the front side of the upper end of the separation box 12. A dewatering pressure plate 31 is fixedly connected to the lower end of the inner movable rod of the hydraulic cylinder 30. The extension driven by the hydraulic cylinder 30 can drive the dewatering pressure plate 31 to move downward, thereby squeezing and dewatering the material residue in the filter screen cylinder 14 at the corresponding position.

[0033] An electric push rod 32 is fixedly connected to the lower right end of the interior of the separation box 12. A push plate 33 is fixedly connected to the upper end of the movable rod inside the electric push rod 32. The upper end face of the push plate 33 is in contact with the lower end face of the filter screen cylinder 14. A material inlet is opened on the right side of the upper wall of the separation box 12. The push plate 33 can push the filter screen cylinder 14 at the material inlet upward by the extension of the electric push rod 32, so as to facilitate the removal of the dewatered residue.

[0034] Working principle of this utility model: When in use, wastewater is injected into the pretreatment tank 7 through the inlet pipe 8. The rotation of the second motor 21 causes the guide wheel 22 to rotate. The wastewater enters the inlet pipe 25 after being filtered through the front outlet and the coarse filter screen 23. The filtered particulate impurities are guided downwards and finally discharged through the slag discharge frame 24. During the rotation of the guide wheel 22, some of the wastewater carried by it enters the inlet pipe 25 through the branch pipe 26. Finally, the coarsely filtered wastewater enters the rear treatment tank of the rotating inner tank 4. The rotation of the first stepper motor 16 causes the inner rotating chamber 4 to rotate under the support of the supporting balls 17. When the wastewater treatment tank rotates to the left and front sides, the rotation of the third motor 28 causes the chemical feeding wheel 27 to quantitatively feed different chemicals and flocculants into the treatment tank, avoiding the problem of poor wastewater treatment effect due to inaccurate chemical addition. In conjunction with the rotation of the first motor 18, the transmission gear 19 drives the driven gear 20 to rotate, so that the mixing blade 5 and the side wall... The scraper 6 can fully mix the agent and sewage, causing the sewage to flocculate. After the inner rotating chamber 4 rotates and drives the flocculated treatment tank to move to the right end, the flocculated sewage is discharged through the guide pipe 11, realizing continuous purification and flocculation treatment of sewage. After the sewage enters the separation box 12 through the guide pipe 11, it first enters the filter screen 14 on the left. The filter screen 14 can separate most of the water, which falls downward into the lower part of the separation box 12. The second stepper motor 29 drives the rotating circular frame 13 to rotate. After the separating screen cylinder is positioned below the dewatering pressure plate 31, the hydraulic cylinder 30 drives the dewatering pressure plate 31 to squeeze and dewater the sludge and flocculents inside the filter screen cylinder 14, so that the dewatered water is discharged through the drain pipe 15. The remaining material residue, after rotating to the right end with the rotating frame 13, is lifted upward with the filter screen cylinder 14 by the pushing action of the electric push rod 32 and the push plate 33, so that the material residue can be removed without affecting the normal operation of the equipment and improving the wastewater treatment efficiency.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
