Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a buffer base for a compressor. Background Art

[0002] In sewage treatment operations, it is often necessary to use air compressors to stir the sewage treatment pool. The working principle of the compressor is to generate bubbles through the aeration device, improve the fluidity of the sludge, promote the mutual collision, dispersion and suspension of the sludge particles, and achieve the stirring effect. When the air compressor is in use, it is easy to vibrate due to the operation of the internal motor, affecting the working accuracy and service life of the compressor. It is necessary to install a buffer base to protect the compressor safely.

[0003] After searching, Chinese patent announcement number: CN208153289U discloses a buffer base for air compressor, including a protective seat, a plurality of movable rods are connected through the upper ends of the protective seat, the lower ends of the movable rods are connected to the inside of the protective seat, and a clamping plate is fixedly connected, and a compression spring is nested and connected between the clamping plate and the protective seat on the outer side of the lower end of the movable rod, and a telescopic rod is fixedly connected to the top of the inner side of the protective seat between the plurality of compression springs. The patent effectively dissolves the impact force generated by the air compressor during operation by elastically connecting the clamping plate with the compression spring, and elastically connecting the fixed seat with the buffer spring, so that the air compressor can work more smoothly. However, the impact force generated by the air compressor during operation will cause the buffer spring to vibrate back and forth. Although it has a certain buffering capacity, the buffer spring will drive the compressor to move in the opposite direction after being compressed and rebounded. The compressor will still vibrate continuously under the rebound force of the spring, which reduces the buffering effect and affects the working accuracy and service life of the compressor. Therefore, a buffer base for compressor is proposed to solve the above problems. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1The utility model provides an embodiment: a buffer base for a compressor, including a base 1, which plays a supporting and stabilizing role, and is used to improve the stable operation of the compressor body 4 when it is working. The bottom of the circumferential surface of the base 1 is fixedly connected with a mounting plate 2 for stably mounting the base 1 on an external working platform. The surface of the mounting plate 2 is provided with mounting holes 3, and the number of mounting holes 3 is set to be multiple. The multiple mounting holes 3 are arranged on the surface of the mounting plate 2 in a ring shape with equal intervals. The mounting plate 2 can be stably fixed to the ground by inserting threaded rods into the mounting holes 3 and tightening them. A buffer mechanism is arranged inside the base 1, and a compressor body 4 is arranged on the top of the base 1 for providing driving force to sewage during sewage treatment. The compressor body 4 is connected to the base 1 through the mounting mechanism.

[0031] Reference Figure 2 - Figure 3 The mounting mechanism includes a fixing plate 5, a threaded hole is provided on the top of the base 1, the fixing plate 5 is fixedly mounted on the bottom of the compressor body 4, the fixing plate 5 is detachably connected to the base 1 through a fastening bolt 6, the number of the fastening bolts 6 is set to be multiple, the mounting mechanism also includes an elastic washer 7, the number of the elastic washers 7 is equal to the number of the fastening bolts 6, the elastic washer 7 is sleeved on the circumferential surface of the fastening bolt 6, the bottom of the fixing plate 5 is elastically connected to the top of the base 1 through the elastic washer 7, and an upward elastic force is applied to the fixing plate 5 by setting the elastic washer 7, so that the vibration energy generated by the compressor body 4 during operation is absorbed, thereby improving the stability of the compressor body 4.

[0032] Reference Figure 2 , Figure 4 The buffer mechanism includes a vertically arranged buffer column 8, which penetrates and is slidably installed on the inner wall of the base 1. The sliding direction of the buffer column 8 is up and down sliding. The top of the buffer column 8 contacts the bottom of the compressor body 4. The vibration energy generated when the compressor body 4 is working causes the compressor body 4 to vibrate slightly at the installation position, thereby driving the buffer column 8 to move up and down. The buffer mechanism also includes a limit plate 9 set in a circular plate shape, which is fixedly installed on the circumferential surface of the buffer column 8. The bottom of the limit plate 9 is elastically connected to the top of the base 1 through a buffer spring 10. The buffer spring 10 is sleeved on the outer surface of the buffer column 8. The buffer spring 10 applies an upward elastic force to the buffer column 8. The buffer mechanism also includes a connecting rod 11, which is inclined. One end of the connecting rod 11 is hinged to the circumferential surface of the buffer column 8, and the other end of the connecting rod 11 is hinged with a slider 12. The number of connecting rods 11 and sliders 12 is set to be multiple and equal.

[0033] Reference Figure 2 , Figure 4The buffer mechanism also includes a slide groove 13, which is opened at the bottom of the base 1. The slider 12 is slidably installed on the inner wall of the slide groove 13. The buffer column 8 moves up and down through the transmission action of the connecting rod 11, so that the slider 12 moves linearly in the radial direction of the buffer column 8. The buffer mechanism also includes an extrusion column 14 arranged in a cylindrical shape. The extrusion column 14 is fixedly installed at one end of the slider 12 away from the center of the base 1. A rubber ball 15 with good damping effect is fixedly connected to the inner wall of the base 1. The sliding damping on the surface of the rubber ball 15 is large. When the extrusion column 14 moves, it rubs against the surface of the rubber ball 15, which can slow down the movement speed of the extrusion column 14. The rubber ball 15 contacts the end of the extrusion column 14 away from the slider 12.

[0034] Working principle: When in use, insert the threaded rod into the mounting hole 3 and tighten the threaded rod to fix the mounting plate twice as firmly on the external working platform, thereby improving the stability of the compressor body 4 above the base 1 during sewage treatment. Align the fixing plate 5 at the bottom of the compressor body 4 with the threaded hole above the base 1, and then fix the compressor body 4 above the base 1 by tightening the fixing bolts 6 to complete the installation and commissioning of the equipment.

[0035] The small-amplitude vibration generated when the compressor body 4 is working drives the buffer column 8 to move downward. The displacement of the buffer column 8 drives the limit plate 9 to overcome the elastic force of the buffer spring 10 and move downward, and the length of the buffer spring 10 is compressed, thereby absorbing a portion of the vibration energy of the compressor body 4. When the buffer column 8 moves downward, it will also drive the slider 12 to move away from the center of the base 1 through the connecting rod 11. The displacement of the slider 12 drives the extrusion column 14 to move away from the center of the base 1. During the displacement of the extrusion column 14, sliding friction occurs between the surface of the extrusion column 14 and the surface of the rubber ball 15, which slows down the movement speed of the extrusion column 14, and cooperates with the rebound ability of the buffer spring 10 to improve the effect of buffering and vibration reduction.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
