Description

Technical Field

[0001] The invention belongs to the technical field of glucose storage tank lifting, and in particular relates to a glucose storage tank lifting device and a lifting method for sewage treatment. Background Art

[0002] In the biological treatment process of sewage treatment, especially aerobic biological treatment process, microorganisms need carbon sources to maintain growth and metabolic activities to decompose organic pollutants in sewage. Glucose can be added to the sewage treatment system as a high-quality carbon source to provide energy and nutrients for microorganisms. For large sewage treatment plants, liquid glucose is usually used. From the perspective of convenience of addition, glucose in the storage tank is transported to the treatment process through a pipeline system, and the metering is relatively easy to control.

[0003] For the liquid glucose delivery system that enters the treatment process by gravity flow, the storage tank needs to have a certain height to ensure that sufficient pressure can be provided to allow the liquid to flow out smoothly. Since the tank body of the glucose storage tank is large, special lifting equipment is required to lift it. In existing equipment, a rope is usually tied to the outside of the tank body, and the operator hangs the rope on the hook to achieve the lifting operation of the tank body. However, when the tank body is lifted to the specified height, the hook will detach from the rope body by descending and then lift the next group of tank bodies again. However, in this method, since the rope body is relatively soft, the hook may be entangled with the rope body when it descends, and it still needs to be manually untangled. The operation process is cumbersome, time-consuming and labor-intensive, thereby reducing the lifting efficiency. Therefore, in order to solve the above problems, a lifting device and lifting method for a glucose storage tank for sewage treatment are proposed. Summary of the invention

[0014] Preferably, the cylinder is also provided with a protection component located above the support component;

[0015] The protection component comprises an elastic connecting rod elastically hinged to the inside of the cylinder, and one end of the elastic connecting rod extends to the outside of the cylinder to abut against the inner wall of the pipe mouth of the storage tank body.

[0016] Preferably, the protection assembly further comprises a push rod movably connected to the inside of the cylinder and a positioning hole provided on the elastic connecting rod, wherein the bottom end of the push rod passes through the elastic inclined block and extends to the bottom of the elastic inclined block;

[0021] S2, when the cylinder body moves downward through the top of the storage tank body and enters the storage tank body, the tank mouth of the storage tank body will first squeeze the support rod and turn it upward. During this process, the support rod will drive the end of the spring combination rod to first push the elastic pick to rotate and then enter the slot through the slide groove. Then the cylinder body continues to move downward and the support rod passes through the tank mouth and resets and opens. At this time, the end of the spring combination rod abuts against the bottom of the elastic pick;

[0022] S3, then the cylinder body moves upward, the opened support rod will abut against the inner wall of the storage tank body and rotate downward during the upward movement of the cylinder body.

When the end of the spring combination rod contacts the top of the bending groove, the support rod cannot rotate. At this time, the cylinder body can move upward to lift the tank body, eliminating the problem of cumbersome rope hanging process and reduced lifting efficiency during the lifting of the tank body.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 8 As shown, the present invention provides a glucose storage tank lifting device for sewage treatment, comprising a cylinder 1 and a storage tank body 6, wherein a steel cable 11 is arranged on the top of the cylinder 1, and further comprising: an adjustment component 3, which is movably mounted on the bottom of the cylinder 1; a support component 2, which is arranged in a circumferential array on the cylinder 1;

[0038] The adjustment component 3 includes a column 31 movably connected to the bottom of the cylinder 1. The column 31 is provided with a bending groove 32, a vertical groove 33 and a slide groove 34 in an array on the outer circumference. The top and bottom of the bending groove 32 are vertical and inclined respectively. The bottom end of the vertical groove 33 is connected to the bottom end of the bending groove 32 and the slide groove 34. The top end of the slide groove 34 is connected to the bending part of an adjacent group of bending grooves 32. An elastic paddle 35 located at the connection between the vertical groove 33 and the slide groove 34 is elastically hinged on the column 31. The depths of the vertical groove 33 and the bending groove 32 are equal and both are greater than the depth of the slide groove 34.

[0039] The support assembly 2 includes a support rod 21 hinged on the cylinder 1, a convex shaft 22 is symmetrically fixed to the support rod 21, an elastic member 23 for supporting the convex shaft 22 is fixedly connected to the cylinder 1, and a spring combination rod 24 whose ends can slide in the column 31, the bending groove 32, the vertical groove 33 and the sliding groove 34 respectively is elastically supported inside the support rod 21;

[0040] In the initial state, the end of the support rod 21 is located at the bottom of the vertical groove 33 and abuts against the top of the elastic pick 35. The cylinder 1 is also provided with a circumferential array of notches 12, and the top of the notch 12 can be connected to the bottom of the slide groove 34.

[0041] The top height of the vertical groove 33 is higher than the top height of the bending groove 32;

[0042] By adopting the above scheme, when the cylinder 1 descends, it enters the storage tank body 6 from the top of the storage tank body 6. First, the tank mouth of the storage tank body 6 will squeeze the support rod 21 and make it flip upward. In this process, the support rod 21 will drive the end of the spring combination rod 24 to first push the elastic paddle 35 to rotate and enter the slot 12. Then the cylinder 1 continues to descend and the support rod 21 passes through the tank mouth and resets and opens. At this time, the end of the spring combination rod 24 abuts against the bottom of the elastic paddle 35. Then the cylinder 1 goes up, and the opened support rod The support rod 21 will abut against the inner wall of the storage tank body 6 and rotate downward during the upward movement of the cylinder 1. During this process, the support rod 21 will also drive the end of the spring combination rod 24 to enter the bending groove 32 from the top of the slide groove 34 under the guidance of the elastic paddle 35. When the end of the spring combination rod 24 abuts against the top of the bending groove 32, the support rod 21 cannot rotate. At this time, the cylinder 1 can move upward to lift the storage tank body 6, eliminating the problem of cumbersome rope hanging process and reduced lifting efficiency during the lifting of the tank body.

[0043] At the same time, after the tank body 6 is lifted to the specified position, the cylinder 1 moves downward to release the support rod 21 from the contact with the inner wall of the tank body 6. The support rod 21 will rotate and reset under the action of the elastic force of the elastic member 23. At this time, the end of the spring combination rod 24 is at the bottom of the vertical groove 33 and contacts the top of the elastic paddle 35. At this time, the cylinder 1 moves upward, and the support rod 21 will rotate downward due to the squeezing of the inner wall of the tank body 6, so that the end of the spring combination rod 24 slides to the top of the vertical groove 33. At this time, the slope of the support rod 21 is greater than the slope when the support rod 21 lifts the tank body 6. At this time, the support rod 21 can be detached from the tank body 6 through the tank mouth of the tank body 6, which solves the problem that the rope untying process during lifting of the tank body may require manual intervention and reduce the lifting efficiency.

[0044] like Figure 1-Figure 6 As shown, the cylinder 1 is also elastically connected to an elastic inclined block 4 located above the spring combination rod 24, and the bottom of the elastic inclined block 4 is inclined toward the column 31;

[0045] When the elastic inclined block 4 moves upward, the spring on the upper part thereof will be compressed; when the end of the support rod 21 moves upward to the bending position of the bending groove 32, a gap is left between the end of the support rod 21 and the bottom of the elastic inclined block 4;

[0046] The top of the elastic inclined block 4 is columnar; a protrusion 311 located just above the vertical portion of the vertical slot 33 is fixedly connected to the top of the column 31, and when the end of the spring combination rod 24 slides in the vertical portion of the bending slot 32, the top of the elastic inclined block 4 abuts against the protrusion 311;

[0047] By adopting the above scheme, when the spring combination rod 24 goes up along the vertical part of the bending groove 32, the top end of the spring combination rod 24 will be restricted by the bottom inclined surface of the elastic inclined block 4, thereby ensuring that when the support rod 21 is lifting the tank body 6, the top end of the spring combination rod 24 can always be in the bending groove 32, thereby improving the stability of the device when lifting the tank body 6.

[0048] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, when the end of the spring combination rod 24 slides from the bottom of the bending groove 32 to the vertical groove 33 and moves upward along the vertical groove 33, the protrusion 311 and the top of the elastic inclined block 4 are misaligned in the vertical direction. At this time, the bottom end of the elastic inclined block 4 is squeezed by the top of the spring combination rod 24 and can move upward;

[0049] By adopting the above scheme, when the spring combination rod 24 slides into the vertical groove 33, since the protrusion 311 and the elastic inclined block 4 are misaligned in the vertical direction, the cylinder 1 moves upward, and the support rod 21 is squeezed by the inner wall of the tank body 6 and rotates, driving the end of the spring combination rod 24 to slide to the top of the vertical groove 33 and push the elastic inclined block 4 upward. At the same time, the support rod 21 can also detach from the tank body 6 through the tank mouth of the tank body 6.

[0050] like Figure 1-Figure 6 As shown, the cylinder 1 is also provided with a protection assembly 5 located above the support assembly 2; the protection assembly 5 includes an elastic connecting rod 52 elastically hinged inside the cylinder 1, and one end of the elastic connecting rod 52 extends to the outside of the cylinder 1 to abut against the inner wall of the pipe mouth of the storage tank body 6;

[0051] The protection assembly 5 further includes a push rod 51 movably connected to the inside of the cylinder 1 and a positioning hole 53 provided on the elastic connecting rod 52. The bottom end of the push rod 51 penetrates the elastic inclined block 4 and extends to the bottom of the elastic inclined block 4.

[0052] The inner diameter of the positioning hole 53 is larger than the diameter of the push rod 51 and the top end of the push rod 51 can be inserted into the positioning hole 53 when the push rod 51 moves upward; the push rod 51 is also provided with a step located above the elastic inclined block 4 for limiting the descending distance of the push rod 51;

[0053] By adopting the above scheme, when the end of the spring combination rod 24 abuts against the elastic inclined block 4, the end of the spring combination rod 24 will first push the push rod 51 upward and make the top of the push rod 51 fit into the positioning hole 53. At this time, the angle of the elastic connecting rod 52 is restricted. At this time, the gap between the bending part of the elastic connecting rod 52 and the inner wall of the tank mouth of the tank body 6 can be reduced, thereby reducing the shaking amplitude of the cylinder 1 inside the tank body 6, thereby improving the stability of the device when lifting the tank body 6.

[0054] The working principle and use process of the present invention:

[0055] First, the steel cable 11 is controlled by the hoisting equipment to drive the cylinder 1 upward or downward;

[0056] When the cylinder 1 passes through the top of the storage tank body 6 and enters the storage tank body 6 while descending, the tank mouth of the storage tank body 6 will first squeeze the support rod 21 and make it flip upward. During this process, the support rod 21 will drive the end of the spring combination rod 24 to first push the elastic pick 35 to rotate and then enter the slot 12. Then, the cylinder 1 continues to descend and the support rod 21 passes through the tank mouth and resets and opens. At this time, the end of the spring combination rod 24 abuts against the bottom of the elastic pick 35.

[0057] Then the cylinder 1 moves upward, the opened support rod 21 abuts against the inner wall of the storage tank body 6 and rotates downward during the upward movement of the cylinder 1. During this process, the support rod 21 also drives the end of the spring combination rod 24 to enter the bending groove 32 from the top of the slide groove 34 under the guidance of the elastic paddle 35. When the end of the spring combination rod 24 abuts against the top of the bending groove 32, the support rod 21 cannot rotate. At this time, the cylinder 1 moves upward to lift the storage tank body 6.

[0058] When the tank body 6 is lifted to the specified position, the cylinder 1 moves downward, causing the support rod 21 to first release the contact with the inner wall of the tank body 6, and the support rod 21 will rotate and reset under the action of the elastic force of the elastic member 23. At this time, the end of the spring combination rod 24 is at the bottom of the vertical groove 33 and abuts against the top of the elastic paddle 35. At this time, the cylinder 1 moves upward, and the support rod 21 will be squeezed by the inner wall of the tank body 6 and rotate downward, so that the end of the spring combination rod 24 slides to the top of the vertical groove 33. At this time, the slope of the support rod 21 is larger than the slope when the support rod 21 lifts the tank body 6. At this time, the support rod 21 can be detached from the tank body 6 through the tank mouth of the tank body 6.
