Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sludge deposition thickness measuring device for wastewater treatment supervision. Background Technology

[0002] After the sewage is treated in the sewage tank, it needs to be discharged. Then, the depth of the sludge in the sewage needs to be measured. The amount of sludge deposited in the tank is calculated based on the length of the treatment tank. The current method for measuring sludge is to insert a measuring ruler into the sludge in the sewage tank to check the depth of the sludge. However, if the sludge accumulated in the sewage tank is thick, it will be very difficult for the measuring personnel to continue inserting the measuring ruler into the sludge after it has been inserted deep into the sludge. To address this problem, a device exists, such as Chinese Utility Model Patent No. CN214620965U, which discloses a sludge deposition measuring device for sewage discharge treatment tanks used in supervision. The device includes a carrier box, a lifting motor fixedly connected to one side of the carrier box, an output shaft driven by the lifting motor near the carrier box, the output shaft penetrating the carrier box near the lifting motor and extending into the carrier box, a clamping tube fixedly connected to the end of the output shaft away from the lifting motor, a drive rod rotatably connected inside the carrier box, the drive rod away from the lifting motor penetrating the carrier box and extending to the side of the carrier box away from the lifting motor, a drive worm gear fixedly connected to the outer wall of the drive rod, a clamping rod fixedly connected to the end of the drive worm gear away from the drive rod, and a hexagonal slot adapted to the outer wall of the clamping rod provided at the end of the clamping tube near the clamping rod. The device uses a motor-driven worm gear structure to insert a scale rod into the sludge to measure the sludge thickness. However, if the scale rod is directly inserted into the sludge, the sludge will adhere to the scale rod, obscuring the scale and affecting the reading. Furthermore, as a standard measuring component, the scale rod should be kept clean. If the scale rod is directly inserted into the sludge for measurement, it will affect the service life of the scale rod in the long run. Utility Model Content

[0003] The purpose of this invention is to provide a sludge deposition thickness measuring device for wastewater treatment supervision. This invention employs a separate measuring rod and scale rod structure to measure sludge thickness, improving measurement accuracy and maintaining a clean and clear scale.

[0004] The technical solution of this utility model is as follows: a sludge deposition thickness measuring device for sewage treatment supervision, comprising a supporting main frame, a longitudinal lifting assembly on the supporting main frame, a right-angle frame on the upper part of the longitudinal lifting assembly, a screw motor on the right-angle frame, and a screw rod connected to the output end of the screw motor; a positioning cylinder at the end of the longitudinal lifting assembly, a measuring rod inside the positioning cylinder via a limiting structure, the measuring rod being connected to the screw rod via a threaded part, a reference seat at the end of the positioning cylinder, and a pointer on the side of the reference seat; a scale rod placement frame on the side of the positioning cylinder, a scale rod that can be raised and lowered and slidably placed inside the scale rod placement frame, the pointer corresponding to the scale on the scale rod, and a sliding auxiliary component on the scale rod, the auxiliary component being flush with and corresponding to the end of the measuring rod.

[0005] In the aforementioned sludge deposition thickness measuring device for sewage treatment supervision, the longitudinal lifting assembly includes a slide rail disposed on one side of the column of the main support frame, and a matching movable seat is provided on the slide rail; a cylinder is provided at the upper end of the main support frame, the extended end of the cylinder is connected to the movable seat, and the positioning cylinder is disposed at one end of the movable seat.

[0006] In the aforementioned sludge deposition thickness measuring device for sewage treatment supervision, the inner side of the positioning cylinder is provided with a longitudinal limiting groove extending along its length direction, and the side of the measuring rod has a side strip that slides in cooperation with the longitudinal limiting groove.

[0007] In the aforementioned sludge deposition thickness measuring device for sewage treatment supervision, the inner side of the scale rod placement frame has a through groove, and the inner wall of the through groove has a side groove communicating with the through groove; the upper end of the measuring rod has a guide post that fits into the through groove, and the side of the guide post has ribs that fit into the side groove.

[0008] In the aforementioned sludge deposition thickness measuring device for wastewater treatment supervision, the pointer includes a main rod connected to a reference base, one end of which has a tip that is perpendicular to the scale surface of the scale rod and aligned with its scale.

[0009] In the aforementioned sludge deposition thickness measuring device for wastewater treatment supervision, the auxiliary component includes a sliding block sleeved on a scale rod, with a screw on one side of the sliding block abutting against the scale rod; a horizontal rod is hinged to the front side of the sliding block, and the horizontal rod can be rotated to be flush with the end of the measuring rod.

[0011] In the aforementioned sludge deposition thickness measuring device for wastewater treatment supervision, the movable base is a movable base with ribs.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. In this utility model, the longitudinal lifting assembly can drive the positioning cylinder to descend smoothly until the reference seat at the end of the positioning cylinder accurately contacts the sludge surface. At this point, the longitudinal lifting assembly immediately stops operating. Simultaneously, the scale rod, upon contacting the sludge surface, will smoothly move upward along the scale rod placement bracket. Then, the screw motor is started. The screw motor, with its stable power output, drives the screw rod to rotate at high speed. Since the screw rod and the measuring rod are tightly connected by threads, the measuring rod will gradually penetrate into the sludge under the drive of the screw rod until the end of the measuring rod reliably contacts the bottom of the sewage tank. At this point, the screw rod... After the rotary motor stops running, the longitudinal lifting assembly begins to reset, slowly raising the reference base and measuring rod. The scale rod then falls naturally, and the auxiliary component is moved flexibly to ensure that it is precisely aligned with the end of the measuring rod. At this point, the pointer will accurately point to the corresponding scale on the scale rod. By reading the scale value between the pointer and the auxiliary block, the sludge thickness can be obtained quickly and accurately. This separate structure design of the measuring rod and the scale rod not only significantly improves the accuracy of the measurement but also ensures that the surface of the scale rod is always clean and the scale is clear, effectively avoiding measurement errors caused by the scale being obstructed.

[0014] 2. The scale rod of this utility model adopts a rib and side groove structure for guidance. During the movement of the scale rod, the rib and side groove are closely matched, which provides a solid and reliable guarantee for the smooth movement of the scale rod, greatly improves the stability of the scale rod in the measurement process, and further ensures the accuracy of the measurement results.

[0015] 3. The auxiliary component of this utility model is used to assist in reading the measurement. It allows the sliding block to be easily moved along the scale bar to the corresponding position, ensuring that the horizontal bar is closely aligned with the end of the measuring rod and precisely flush with it. This design greatly improves the convenience of reading the measurement, effectively reduces the difficulty for operators, and improves the overall efficiency of the measurement work.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0024] Example: A sludge deposition thickness measuring device for wastewater treatment supervision, including a main support frame 1, as shown in the attached diagram. Figure 1 As shown, the main support frame is placed beside the sewage tank. A longitudinal lifting assembly 2 is installed on the main support frame 1. A right-angle frame 3 is installed on the upper part of the longitudinal lifting assembly 2. A screw motor 4 is installed on the right-angle frame 3, and the output end of the screw motor 4 is connected to a screw rod 5. The movable end of the longitudinal lifting assembly 2 is equipped with a positioning cylinder 6. The longitudinal lifting assembly 2 includes a slide rail 13 located on one side of the column of the main support frame 1. A matching movable seat 14 is provided on the slide rail 13. The right-angle frame 3 is connected to the movable seat 14 with bolts, facilitating the installation and disassembly of the two components. The movable seat 14 has... The ribbed movable seat 14 enhances the structural strength of the movable seat through the ribs; a cylinder 15 is provided at the upper end of the supporting main frame 1, and the extended end of the cylinder 15 is connected to the movable seat 14. The extended end of the cylinder has double nuts. When the extended end of the cylinder is installed with the movable seat, the lower nut is removed, the extended end of the cylinder passes through the movable seat, and then the lower nut is screwed on, with one nut close to the upper part of the movable seat and the other close to the lower part, thus connecting the extended end of the cylinder to the movable seat; the positioning cylinder 6 is located at one end of the movable seat 14, and a measuring rod 7 is provided inside the positioning cylinder 6 via a limiting structure, as shown in the attached diagram. Figure 3As shown, the measuring rod 7 is connected to the screw rod 5 via a threaded part. The rotation of the screw rod causes the measuring rod to move up and down along the positioning cylinder. The end of the positioning cylinder 6 has a reference seat 8. The reference seat plays the role of positioning and measurement start mark in this sludge deposition thickness measuring device. The pointer set on the side of the reference seat, together with the scale rod, provides an intuitive reading reference for measuring the sludge thickness. To ensure accuracy, the sludge is leveled at the measurement point to allow the reference base to be placed stably. A pointer 9 is connected to the side of the reference base 8. The pointer 9 includes a main body rod 22 connected to the reference base 8. One end of the main body rod 22 has a tip 26, which is perpendicular to and aligned with the scale surface of the scale rod 11. The pointer can be detached. A scale rod holder 10 is provided on the side of the positioning cylinder 6. A scale rod 11 that can be raised and lowered and slidably is provided inside the scale rod holder 10. The pointer 9 corresponds to the scale on the scale rod 11. The scale rod 11 has a slidable auxiliary component 12, which is flush with the end of the measuring rod 7. The auxiliary component 12 includes a sliding block 23 fitted onto the scale rod 11, as shown in the attached figure. Figure 6 As shown, one side of the sliding block 23 has a screw 24 that abuts against the scale rod 11. After the sliding block moves to a certain position, the screw is tightened to position the sliding block. A horizontal rod 25 is hinged to the front side of the sliding block 23. The horizontal rod 25 can be rotated to be flush with the end of the measuring rod 7. The auxiliary component is used to assist in reading the measurement. It can easily move the sliding block along the scale rod to the corresponding position, so that the horizontal rod is close to the end of the measuring rod and is accurately kept flush with the end of the measuring rod. The end of the measuring rod is a pointed tip, that is, the horizontal rod and the pointed tip are kept horizontal. The reading state is as shown in the attached figure. Figure 2 As shown. This design greatly improves the convenience of reading, effectively reduces the difficulty of reading for operators, and improves the overall efficiency of measurement work. Without auxiliary parts, there is a gap between the end of the measuring rod and the scale rod, and reading by visual inspection will result in inaccurate readings. The gap between the pointer and the scale rod prevents the movement of the sliding block from interfering with the pointer. The horizontal rod and the sliding block are connected by screws. When the horizontal rod is rotated, it becomes flush with the end of the measuring rod, and the width of the horizontal rod is the same as the thickness of the sliding block. After rotating it to be flush, the screw is tightened. The inner side of the positioning cylinder 6 is provided with a longitudinal limiting groove 16 extending along its length. The side of the measuring rod 7 has a side strip 17 that slides with the longitudinal limiting groove 16. Only through this limiting structure can the longitudinal movement of the measuring rod be realized.

[0025] The inner side of the scale rod holder 10 has a through groove 18, and the inner wall of the through groove 18 has a side groove 19 communicating with the through groove 18, as shown in the attached figure. Figure 5 As shown; the upper end of the measuring rod 7 has a guide post 20 that matches the through groove 18, as shown in the attached figure. Figure 4As shown, the guide post 20 has ribs 21 on its side that fit into the side groove 19. The scale rod is guided by the rib and side groove structure. During the movement of the scale rod, the ribs and side grooves are closely engaged, providing a solid and reliable guarantee for the smooth movement of the scale rod, greatly improving the stability of the scale rod during the measurement process, and further ensuring the accuracy of the measurement results.

[0026] The working principle of this utility model is as follows: The longitudinal lifting assembly 2 is activated, and the cylinder 15 on the main support frame 1 pushes the moving seat 14, causing the positioning cylinder 6 to descend smoothly. When the reference seat 8 at the end of the positioning cylinder 6 precisely contacts the sludge surface, the longitudinal lifting assembly 2 stops operating. Simultaneously, the scale rod 11, upon contacting the sludge surface, moves smoothly upward along the scale rod placement frame 10. The screw motor 4 on the right-angle frame 3 is activated, driving the screw rod 5 at the output end to rotate at high speed. Since the screw rod 5 and the measuring rod 7 are tightly connected by threads, the measuring rod 7, driven by the screw rod 5, gradually penetrates into the sludge along the longitudinal limiting groove 16 inside the positioning cylinder 6. The side strip 17 on the side of the measuring rod 7 engages with the longitudinal limiting groove 16, ensuring that the measuring rod 7 descends vertically and stably until the end of the measuring rod 7 reliably contacts the bottom of the sewage tank. At this point, the screw motor 4 stops operating. The longitudinal lifting assembly 2 begins to reset, slowly lifting the reference seat 8 and the measuring rod 7, while the scale rod 11 naturally falls downward. The auxiliary part 12 on the movable scale rod 11 is moved, and the horizontal rod 25 is rotated to the side of the measuring rod 7. The horizontal rod 25 on the front side of the sliding block 23 is precisely aligned with the end of the measuring rod 7. The position of the sliding block 23 is fixed by tightening the screw 24. At this time, the pointer 9 on the side of the reference seat 8 accurately points to the corresponding scale on the scale rod 11. By reading the scale value between the pointer 9 and the sliding block 23, the sludge thickness can be obtained quickly and accurately.
