Description

Technical Field

[0001] This utility model relates to the field of circulating water treatment technology, and specifically to a pretreatment device for circulating water treatment equipment. Background Technology

[0002] Pretreatment of circulating water is a crucial step in industrial production. Its main purpose is to ensure the stability and reliability of the circulating water quality through a series of treatment processes to meet production requirements. Suspended solids and particulate matter in circulating water can cause equipment blockage and water quality deterioration. Therefore, these particulate impurities need to be removed through filtration.

[0003] Utility model patent CN216986717U discloses a wastewater pretreatment device, comprising: a box body with a hollow interior forming a receiving space and an opening at the top; an inlet located on the side wall of the box body; an outlet located on the bottom wall of the box body; a toothed disc located at the opening, coaxially arranged and rotatably connected to the box body; a screen barrel coaxially arranged with the box body, capable of being fitted inside the box body and hung on the toothed disc; the screen barrel and the inner wall of the box body forming an impurity sedimentation zone; and a scraper assembly for removing sediment in the impurity sedimentation zone. With this technical solution, since the screen barrel and the box body are detachably connected, the screen barrel can be disassembled from the box body after wastewater treatment for cleaning. Based on the scraper assembly, sediment in the impurity sedimentation zone can be cleaned quickly and effectively after wastewater treatment. However, when cleaning filtered particulate impurities, the screen barrel needs to be disassembled, increasing manual operation time and making the cleaning of filtered particulate impurities inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a pretreatment device for circulating water treatment equipment to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A pretreatment device for a circulating water treatment equipment includes a water receiving filter bucket, with a drain pipe above the water receiving filter bucket and a water receiving pipe below the water receiving filter bucket.

[0007] A rotary slag-discharging drive assembly is provided on one side of the water receiving filter bucket. The rotary slag-discharging drive assembly includes a vertical rotating rod. A second conical tooth is fixedly connected to the outer wall of the vertical rotating rod. A first conical tooth meshes with the outer wall of the second conical tooth. The first conical tooth is fixedly connected to the outer wall of the water receiving filter bucket through a crossbar. A collar is rotatably connected to the outer wall of the crossbar. An L-shaped connecting rod is fixedly connected to the bottom surface of the collar. The end of the L-shaped connecting rod away from the collar is fixedly connected to the outer wall of the vertical rotating rod near the bottom end.

[0008] A further improvement of this utility model is that a slag receiving plate is rotatably connected to the outer wall near the bottom of the vertical rotating rod.

[0009] A further improvement of this utility model is that an angle sensor is provided on the outer wall of the vertical rotating rod near the bottom, and a brake stepper motor is fixedly connected to the bottom end of the vertical rotating rod.

[0010] A further improvement of this utility model is that a slag discharge pipe is fixedly connected to the bottom surface of the slag receiving tray.

[0011] A further improvement of this utility model is that a filter screen is fixedly connected to the inner wall of the water receiving filter bucket.

[0012] A further improvement of this utility model is that the number of water receiving filter buckets is four sets, and the four sets of water receiving filter buckets are distributed in a ring at equal intervals on the outer wall of the vertical rotating rod.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. This utility model provides a pretreatment device for circulating water treatment equipment. Four sets of water receiving filter buckets alternately perform filtration and slag discharge, and the impurities can be cleaned without stopping the machine. This solves the problem of intermittent "filtration-slag discharge" in traditional single filter bucket devices, significantly improving the pretreatment efficiency of large-flow circulating water. An angle sensor provides real-time feedback of the rotation angle, and a brake stepper motor precisely controls the movement of the vertical rotating rod, ensuring that the revolution and rotation of the water receiving filter buckets are coordinated and consistent, and guaranteeing the long-term stable operation of the equipment.

[0015] 2. This utility model provides a pretreatment device for a circulating water treatment equipment. Through the meshing transmission of bevel teeth one and bevel teeth two, the water receiving filter bucket rotates synchronously during the revolution. When the opening is downward, it can automatically pour out impurities without manual intervention, reducing labor intensity and avoiding blockage caused by untimely cleaning.

[0016] 3. This utility model provides a pretreatment device for circulating water treatment equipment. The arc-shaped slag receiving tray is adapted to the tilting trajectory of the water receiving filter bucket, ensuring that all impurities fall into the slag receiving tray. It works in conjunction with the slag discharge pipe to achieve directional slag discharge, avoiding secondary pollution caused by the scattering of impurities. At the same time, the cooperation between the brake stepper motor and the angle sensor ensures the precise movement of the water receiving filter bucket, further improving the reliability of slag discharge.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] Example 1

[0025] like Figure 1-4 As shown, this utility model provides a pretreatment device for a circulating water treatment equipment, including a water receiving filter 1, a drain pipe 2 above the water receiving filter 1, and a water receiving pipe 3 below the water receiving filter 1.

[0026] A rotary slag-discharging drive assembly 5 is provided on one side of the water receiving filter hopper 1. The rotary slag-discharging drive assembly 5 includes a vertical rotating rod 8. A second bevel tooth 13 is fixedly connected to the outer wall of the vertical rotating rod 8. A first bevel tooth 12 meshes with the outer wall of the second bevel tooth 13. The first bevel tooth 12 is fixedly connected to the outer wall of the water receiving filter hopper 1 via a crossbar. A collar 11 is rotatably connected to the outer wall of the crossbar. An L-shaped connecting rod 10 is fixedly connected to the bottom surface of the collar 11. The end of the L-shaped connecting rod 10 away from the collar 11 is fixedly connected to the outer wall of the vertical rotating rod 8 near the bottom. An angle sensor 9 is provided on the outer wall of the vertical rotating rod 8 near the bottom. A brake stepper motor 6 is fixedly connected to the bottom of the vertical rotating rod 8.

[0027] There are four sets of water receiving filter buckets 1, which are distributed in a ring at equal intervals on the outer wall of the vertical rotating rod 8.

[0028] In this embodiment, four sets of water-receiving filter buckets 1 alternately perform filtration and slag discharge, and the impurities can be cleaned without stopping the machine. This solves the problem of intermittent "filtration-slag discharge" in traditional single filter bucket devices, significantly improving the pretreatment efficiency of large-flow circulating water. Angle sensor 9 provides real-time feedback on the rotation angle, and brake stepper motor 6 precisely controls the movement of vertical rotating rod 8, ensuring that the revolution and rotation of water-receiving filter bucket 1 are coordinated and consistent, and ensuring long-term stable operation of the equipment.

[0029] Example 2

[0030] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a slag receiving plate 4 is rotatably connected to the outer wall of the vertical rotating rod 8 near the bottom end.

[0031] The bottom surface of the slag receiving tray 4 is fixedly connected to the slag discharge pipe 7.

[0032] A filter screen 14 is fixedly connected to the inner wall of the water receiving filter bucket 1.

[0033] Example 3

[0034] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the module of bevel tooth 12 and bevel tooth 13 is 2mm, and the tooth ratio is 1:1, to ensure that the rotation angle of the water receiving filter bucket 1 matches the revolution angle (rotation 90° when revolution is 90°).

[0035] The radius of curvature of the slag receiving tray 4 is matched with the radius of the revolution trajectory of the water receiving filter 1, ensuring that when the opening of the water receiving filter 1 is downward, the trajectory of the impurities being poured completely covers the slag receiving tray 4.

[0036] Angle sensor 9 is a photoelectric encoder, which is electrically connected to brake stepper motor 6 through PLC controller to realize real-time monitoring of rotation angle and closed-loop control of motor speed.

[0037] The working principle of the pretreatment device of this circulating water treatment equipment will be explained in detail below.

[0038] like Figure 1-4 As shown, the circulating water in the drain pipe 2 is first discharged into the water receiving filter 1. The filter screen 14 on the inner wall of the water receiving filter 1 filters the water flow and intercepts particulate impurities in the water. The filtered clean water is discharged through the water receiving pipe 3 below the water receiving filter 1, realizing the filtration function in the pretreatment.

[0039] The equipment's cyclic operation is driven by a brake stepper motor 6: the brake stepper motor 6 drives the vertical rotating rod 8 to rotate, and the vertical rotating rod 8 drives the collar 11 to rotate synchronously through the L-shaped connecting rod 10; the collar 11 is fitted on the outer wall of the crossbar, one end of the crossbar is fixedly connected to the water receiving filter 1, and the other end is fixed with a bevel tooth 12. Therefore, when the collar 11 rotates, it drives the water receiving filter 1 to make a circular motion (revolution) with the vertical rotating rod 8 through the crossbar; at the same time, the bevel tooth 12 meshes with the bevel tooth 13 fixed on the outer wall of the vertical rotating rod 8, driving the water receiving filter 1 to rotate synchronously during the revolution.

[0040] There are four sets of water receiving filter buckets 1, which are distributed in a ring at equal intervals on the outer wall of the vertical rotating rod 8. In the initial state, the opening of the first set of water receiving filter buckets 1 faces upward and receives water from the drain pipe 2. When the vertical rotating rod 8 rotates 90°, the opening of the second set of water receiving filter buckets 1 faces to the right. When it rotates 180°, the opening of the third set of water receiving filter buckets 1 faces downward, and the particles and debris intercepted inside tilt under their own weight. Since the slag receiving plate 4 is arc-shaped when viewed from above, the debris can fall accurately into the slag receiving plate 4 and be discharged through the slag discharge pipe 7 on the bottom surface of the slag receiving plate 4. When it rotates 270°, the opening of the fourth set of water receiving filter buckets 1 faces to the left. When it rotates 360°, it returns to its original position, completing one cycle.

[0041] Angle sensor 9 monitors the rotation angle of vertical rotating rod 8 in real time and sends the feedback signal to brake stepper motor 6 to achieve precise control of speed and start / stop, ensuring that the revolution and rotation of water receiving filter 1 are coordinated and the filtration and slag discharge process is continuous and uninterrupted.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
