[0031] The pushing mechanism 7 comprises a mounting block 701 fixedly connected to the bottom of the inner wall of the working cylinder 1, a water inlet chamber 702 fixedly connected to the top of the mounting block 701, compression tubes 703 fixedly connected to both sides of the water inlet chamber 702, one end of the compression tube 703 away from the water inlet chamber 702 fixedly connected to the top of the mounting block 701, a telescopic ring 704 fixedly connected to the top of the inner wall of the mounting block 701, an air pressure groove is provided inside the telescopic ring 704, and it will telescope outward when water is injected, and one end of the telescopic ring 704 away from the top of the inner wall of the mounting block 701 is fixedly connected to a side plate 705, the side plate 705 is slidably connected to both sides of the inner wall of the mounting block 701 through a slider, and a pushing component 706 is provided on the inner wall of the side plate 705;

When subjected to external compression, air pressure will be generated and flow into the mounting tube 7061, and one end of the compression bag tube 7066 away from the mounting tube 7061 is fixedly connected to a discharge film 7067, and a discharge block 7068 is fixedly connected to the bottom of the inner wall of the discharge film 7067, and a discharge hole is opened on the surface of the discharge block 7068, through which the mixture inside the discharge film 7067 can be squeezed out.

[0033] The working method of the first embodiment is as follows: when the methyl tert-butyl ether is manufactured, it is taken out, and then the water spray ring 6 is started to spray water into the working cylinder 1. After a part of the water flows to the bottom and enters the water cavity 702, it will be compressed by the compression tube 703 and enter the telescopic ring 704. After receiving the water flow, the telescopic ring 704 will expand and contract outward and drive the side plate 705 to slide downward on the inner wall of the mounting block 701. When the side plate 705 slides downward on the inner wall of the working cylinder 1, the rolling wheel 7063 will roll on the inner wall of the working cylinder 1. At the same time, the water will flow from the side plate 705 into the mounting tube 7061 and from the surface groove of the rolling wheel 7063. The mixture remaining on the inner wall of the working cylinder 1 is flushed out through the hole, and the surface of the rolling wheel 7063 is squeezed by the cylinder wall, which drives the pushing plate 7062 to extend and retract into the mounting tube 7061, and one end of the pushing plate 7062 squeezes the inside of the compression bag tube 7066, so that air pressure is generated inside the compression bag tube 7066 and flows into the mounting tube 7061 to push the rotating ring 7064. After the rotating ring 7064 rotates on the surface of the mounting tube 7061, it drives the cleaning block 7065 to rotate, and the mixture attached to the surface of the cylinder wall and difficult to clean is scraped off by the cleaning block 7065, allowing the mixture to slide to the bottom along the cylinder wall.

[0034] Example 2: Based on Example 1, continue to refer to Figure 5-Figure 6 The cleaning mechanism 8 includes a mounting ring 801, which is fixedly connected to the surface of the connecting rod 5, and the mounting ring 801 is fixedly connected to the bottom of the inner wall of the working cylinder 1. The surface of the mounting ring 801 is fixedly connected with a landslide plate 802, and the landslide plate 802 is fixedly connected to the bottom of the inner wall of the working cylinder 1. A pushing block 803 is slidably connected at the groove hole on the surface of the landslide plate 802. A cleaning component 804 is arranged on the surface of the pushing block 803, and a dispersion component 9 is arranged on the top of the pushing block 803.

[0035] The cleaning component 804 includes a telescopic belt 8041, one end of which is fixedly connected to the surface of the pushing block 803, the surface of the telescopic belt 8041 is fixedly connected to the feeding cavity block 8042, the bottom of the inner wall of the feeding cavity block 8042 is slidably connected to a pushing rod 8043, and both sides of the pushing rod 8043 are fixedly connected to folding rings 8044. The folding ring 8044 has the characteristic of free expansion and contraction, and can drive the two ends of the feeding cavity block 8042 to fold when subjected to external compression, and one end of the folding ring 8044 away from the pushing rod 8043 is fixedly connected to the two ends of the feeding cavity block 8042.

[0036] The cleaning component 804 also includes a connecting block 8045, which is fixedly connected to one end of the telescopic belt 8041. The inner wall of the connecting block 8045 is fixedly connected to an extrusion rod 8046. An air bag is installed at the end of the extrusion rod 8046, which will generate air pressure when squeezed with the cylinder wall. The bottom of the connecting block 8045 is fixedly connected to a material box 8047. Cleaning rings 8048 are fixedly connected to both sides of the inner wall of the material box 8047. The cleaning ring 8048 can be telescoped inwardly, and a scraping groove is provided on the surface to scrape off the mixture at the bottom of the cylinder wall.

[0037] The working method of the second embodiment of the present invention is as follows: the power device in the mounting ring 801 is remotely started to drive the pushing block 803 to rotate in the surface slot of the mounting ring 801, and the pushing block 803 can drive the telescopic belt 8041 to rotate at the bottom of the inner wall of the working cylinder 1. When the telescopic belt 8041 rotates at the bottom of the cylinder wall, the bottom of the feeding cavity block 8042 will contact the bottom of the cylinder wall. After the feeding cavity block 8042 is squeezed, it is compressed inwardly through the folding ring 8044, which will drive the two ends of the feeding cavity block 8042 to stretch inwardly. The mixture at the bottom of the cylinder wall is shoveled into the interior of the feeding cavity block 8042 through the inwardly stretched two ends of the feeding cavity block 8042. At the same time, when the feeding cavity block 8042 rotates to the surface of the landslide plate 802 along with the telescopic belt 8041, the landslide plate 802 is squeezed and contacted with the feeding cavity block 8042 to squeeze the internal mixture into the interior of the landslide plate 802. When the telescopic belt 8041 rotates at the bottom of the cylinder wall , the connecting block 8045 fixed to the end of the telescopic belt 8041 away from the pushing block 803 will contact the cylinder wall, and the squeezing rod 8046 will be squeezed by the cylinder wall, which will cause the squeezing rod 8046 to stretch inward and generate negative pressure suction inside the connecting block 8045. After the material box 8047 contacts the bottom of the cylinder wall, the cleaning ring 8048 will scrape the mixture sliding toward the bottom along the cylinder wall into the material box 8047, and the connecting block 8045 will generate a negative pressure suction force. The negative pressure suction will suck the mixture in the material box 8047 into the telescopic belt 8041 and flow into the feed cavity block 8042. When the bottom of the feed cavity block 8042 is squeezed and contacted with the landslide plate 802, the folding ring 8044 can drive the push rod 8043 to slide inward inside the feed cavity block 8042, and generate pressure on the inside of the feed cavity block 8042, thereby squeezing the mixture inside the feed cavity block 8042 into the inside of the landslide plate 802.

[0038] Example 3: Based on Example 2, continue to refer to Figure 7The dispersion component 9 includes a mounting rod 901, which is fixedly connected to the top of the push block 803. A clamping block 902 is fixedly connected to the surface of the mounting rod 901. A telescopic hole 903 is provided on the surface of the clamping block 902. Moving arms 904 are slidably connected to both sides of the inner wall of the telescopic hole 903 through sliders. An end of the moving arm 904 away from the inner wall of the telescopic hole 903 is fixedly connected to a stretching membrane 905. An absorption groove is provided on the surface of the stretching membrane 905, which can absorb the mixture into the inside and has the function of internal and external expansion. An extrusion block 906 is fixedly connected to the right side of the stretching membrane 905. A slot is provided on the surface of the extrusion block 906, which can squeeze the mixture in the stretching membrane 905 outward.

[0039] Working method of the third embodiment: when the side plate 705 slides to the bottom of the inner wall of the mounting block 701 to the bottom of the inner wall of the working cylinder 1, the discharge film 7067 will also slide to the bottom and absorb the mixture floating on the surface of the water flow into the inside of the discharge film 7067. At this time, when the push block 803 rotates in the slot of the mounting ring 801, it will drive the mounting rod 901 at the top to rotate, and the stretching film 905 will be squeezed and contacted with the discharge block 7068, so that the mixture inside the discharge film 7067 is squeezed out through the discharge block 7068. The mixture is absorbed into the stretch film 905. When the clamp block 902 rotates to the top of the slide plate 802 along with the mounting rod 901, the slide plate 802 squeezes the stretch film 905, causing the movable arm 904 to expand and contract inwardly in the expansion hole 903. The movable arms 904 on both sides drive the stretch film 905 to expand and contract inwardly, thereby squeezing the mixture in the stretch film 905 through the slots on the surface of the squeezing block 906 to the inside of the slide plate 802. Finally, the mixture inside the slide plate 802 flows downwardly from the discharge chute 3 to the dispensing box 2.
