Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, and more specifically, to a device for measuring the height of the mud bed of a deep cone thickener. Background Technique

[0002] A deep cone thickener is an efficient pulp thickening device. Its working principle is that in a machine body with a cylindrical upper part and a conical lower part, the pulp is pretreated by adding a flocculant to make the tiny particles in the pulp coagulate into larger particles. Under the action of gravity, the particles settle in the conical area of the machine body to form a high-concentration pulp. By means of a bottom flow pump or a central rotating thickener, the solid substances in the underflow are discharged to achieve the thickening and separation of the pulp. The height of the mud bed has an important impact on the performance and separation effect of the thickener. Therefore, it is necessary to regularly or real-time monitor the height of the mud bed to ensure the normal operation of the equipment and achieve the best separation effect. At the same time, by measuring the height of the mud bed, potential problems such as mud leakage and equipment failures can be discovered and solved in time, avoiding production accidents and environmental pollution.

[0003] After retrieval, it is found that in the document with the publication number CN219589759U, a device for measuring the height of the mud bed of a deep cone thickener is disclosed. In this document, the mud bed can be measured. However, during the measurement process, the rope will come into contact with the water inside the deep cone thickener. The rope will absorb water and expand, which will weaken the mutual attraction between the rope fibers. When the rope is wound up, the rope will be entangled together, making it difficult for the water inside the rope to evaporate, and corrosion and mildew will occur inside the rope, reducing the strength and durability of the rope. For this reason, we propose a device for measuring the height of the mud bed of a deep cone thickener. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a device for measuring the height of the mud bed of a deep cone thickener.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A device for measuring the height of the mud bed of a deep cone thickener, including a connecting ring. Symmetrically fixed to the outer wall of the connecting ring are two connecting frames. Fixedly connected to the inner walls of the two connecting frames are sliding rods. Springs are sleeved at both ends of the two sliding rods respectively. The circumferential outer walls of the two sliding rods are both slidably connected with sliders. The sliders are slidably connected with the inner walls of the connecting frames. Fixedly connected between the two sliders is a rotating shaft. Rotatably connected to the circumferential outer wall of the rotating shaft is a roller.

[0006] Furthermore, one end of the spring is fixedly connected to the inner wall of the connecting frame, and the other end of the spring is fixedly connected to the slider.

[0007] Further, symmetrically fixed to the outer circumferential wall of the connecting ring are two mounting holes, and rotatably connected to the inner walls of both mounting holes are connecting shafts.

[0008] Further, it further includes a mounting base. Fixedly connected to the top of the mounting base is a support plate, fixedly connected to the top of the support plate is a mounting frame, and both sides of the inner wall of the mounting frame are fixedly connected to the connecting shafts respectively.

[0009] Further, symmetrically fixed to the inner wall of the mounting base are two fixing plates. Rotatably connected between the two fixing plates is a fixed shaft. Fixedly connected to the outer circumferential wall of the fixed shaft is a winding roller. The winding roller is located between the two fixing plates. Rotatably connected to the outer end of the fixed shaft is a crank, and rotatably connected to the end of the crank is a handle.

[0010] Further, fixedly connected to the outer circumferential wall of the winding roller is a traction rope. Scale values are marked on the traction rope. The traction rope is wound in the groove on the outer wall of the winding roller. The end of the traction rope passes through the connecting ring and extends below it. Fixedly connected to the end of the traction rope is a load-bearing cone, and fixedly connected to the bottom of the outer wall of the load-bearing cone is a tray.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. For this sludge bed height measuring device of the deep cone thickener, during winding, the traction rope will drive two rollers to rotate. Under the elastic force of the springs, the two rollers can extrude the surface of the traction rope, discharging most of the water inside the expanded traction rope, thereby protecting the traction rope, reducing the corrosion of the traction rope, and increasing the service life of the traction rope.

[0013] 2. For this sludge bed height measuring device of the deep cone thickener, the tray can increase the contact area with the top of the sludge bed of the deep cone thickener, preventing the load-bearing cone from sinking into the sludge bed and avoiding deviation in the measured height.

[0014] 3. For this sludge bed height measuring device of the deep cone thickener, both ends of the two rotating shafts are connected to sliders. When installing the rollers, the two rotating shafts drive the sliders to slide along the outer wall of the sliding rod respectively, enabling the two rollers to be adjusted according to the size of the traction rope, and at the same time, the distance between the rollers can be adjusted to facilitate the disassembly and replacement of the traction rope.

One end of the spring 6 is fixedly connected to the inner wall of the connecting frame 3, and the other end of the spring 6 is fixedly connected to the slide block 5. The towing rope 18 drives the two rollers 8 to rotate. Under the elastic force of the spring 6, the two rollers 8 can squeeze the surface of the towing rope 18, discharging most of the water inside the expanded towing rope 18, thereby protecting the towing rope 18, reducing the corrosion of the towing rope 18, and improving the service life of the towing rope 18. At the same time, both ends of the two rotating shafts 7 are connected to the slide blocks 5. When installing the roller 8, the two rotating shafts 7 drive the slide blocks 5 to slide along the outer walls of the slide bars 4 respectively, so that the two rollers 8 can be adjusted according to the size of the towing rope 18, and the distance between the rollers 8 can be adjusted to facilitate the disassembly and replacement of the towing rope 18.

[0022] As Figure 1 and Figure 3 shown, two mounting holes 2 are symmetrically and fixedly connected to the circumferential outer wall of the connecting ring 1. Connecting shafts 9 are rotatably connected to the inner walls of the two mounting holes 2. It also includes a mounting seat 12.

[0023] As Figure 1 and Figure 2 shown, two fixing plates 13 are fixedly connected to the inner wall of the mounting seat 12 in a symmetric structure. A fixing shaft 14 is rotatably connected between the two fixing plates 13. A winding roller 15 is fixedly connected to the outer circumferential wall of the fixing shaft 14.

Through the tray 20, the contact area with the top of the mud bed of the deep cone thickener can be increased, preventing the load-bearing cone 19 from sinking into the mud bed and avoiding deviation in the measured height.

[0025] Working principle: Rotate the crank 16 to drive the winding roller 15 to rotate, and lower the traction rope 18 through the winding roller 15 until the tray 20 at the bottom of the load-bearing cone 19 contacts the top of the mud bed of the deep cone thickener. The depth of the existing mud bed can be known through the length of the rope lowered and the depth of the deep cone thickener exposed from the mud bed.
