DETAILED DESCRIPTION

[0028] Other objects and advantages of the utility model will become clear from the following preferred embodiments of the present application.

[0029] As Figure 1 shown, a kind of closed suction device, with inner sleeve 1 and outer sleeve 2 of mutual sleeve connection;And hopper 4 and fan 5, the utility model is transported to the material in hopper 4 in the air flow generated by fan 5 from the material in the ground cylinder, reduces the extrusion to material, improves the delivery efficiency of material.

[0030] The following is described with the taking out of vinasse as an example.

[0031] Suction port 106 is arranged at the lower end of inner sleeve 1, for sucking out vinasse from the ground cylinder;Annular space 201 is formed between inner sleeve 1 and outer sleeve 2, which is used to return the air flow sucked out to the ground cylinder, reduce the volatilization of alcohol and other substances, and form closed circulating air flow to carry vinasse.

[0032] The hopper 4 is in the shape of wide top and narrow bottom, and is provided with an inlet 406 and an air outlet 405 at the upper part of the hopper 4, and is provided with a closable and openable outlet 401 at the lower end. The inlet 406 of the hopper 4 is communicated with the upper end of the inner sleeve 1, and the material sucked by the inner sleeve 1 enters the hopper 4 through the inlet 406.

[0033] The inlet of the fan 5 is communicated with the air outlet 405 of the hopper 4, and forms an air current at the suction port 106 to carry the vinasse into the hopper 4, and the vinasse is settled in the hopper 4; the outlet of the fan 5 is communicated with the annular space 201 through the return air pipe 6, and discharges the air current at the suction port 106 to form a closed circulation loop of the air current, which carries the vinasse and avoids the volatilization of alcohol.

[0034] In some embodiments, the outlet 401 of the hopper 4 is provided with a lower sealing plate 404 capable of sealing the outlet 401, one end of the lower sealing plate 404 is pivotally connected with the hopper 4, and the other end is connected with the hopper 4 through an elastic element 402. In the natural state, the lower sealing plate 404 can seal the outlet 401 of the hopper 4 to prevent external air from entering the hopper 4, which causes the equipment to be unable to effectively suck out the vinasse. When the material in the hopper 4 accumulates to a certain weight, the lower sealing plate 404 is pressed downward, and the vinasse fills the gap between the lower sealing plate 404 and the outlet 401, which can also reduce or avoid the entry of external air into the hopper 4.

[0035] In the hopper 4, a baffle 403 is arranged between the inlet 406 and the air outlet 405, and the baffle 403 extends downward from the inner wall of the hopper 4 by a distance. The baffle 403 can block the vinasse to prevent the air current from carrying the vinasse directly into the fan 5.

[0036] In some embodiments, as shown in Figures 2 to 4 The lower end of the outer sleeve 2 is provided with a material collecting assembly 3, which includes a gear ring 301 rotatably connected with the outer sleeve 2, and material collecting plates 306 uniformly arranged around the gear ring 301. In the circumferential direction, the outer end of the material collecting plate 306 is located on the front side of the rotation direction of the inner end, so that the material collecting assembly 3 can gather the vinasse to the middle and to the lower side of the suction port 106 when it rotates. Preferably, a bearing 305 is arranged between the gear ring 301 and the outer sleeve 2 to reduce the frictional force between them.

[0037] The material collecting assembly 3 further includes a motor 303 and a pinion 304 drivingly connected with the output end of the motor 303. The motor 303 is fixedly connected with the outer sleeve 2. The pinion 304 is engaged with the toothed portion 302 of the gear ring 301 to drive the gear ring 301 to rotate.

[0038] The lower side of the material collecting plate 306 is provided with a plurality of scraping teeth 307, which can scatter the vinasse for easy suction.

[0039] In some embodiments, the aggregate plate 306 comprises a first scraper 308 fixedly connected with the gear ring 301, and a second scraper 309 located radially outside the first scraper 308 and telescopically connected with the first scraper 308, and a spring 310 is arranged between the first scraper 308 and the second scraper 309, so that the second scraper 309 can automatically retract when the aggregate plate 306 touches the inner wall of the silo, thereby avoiding damage to the silo or the device itself. In other embodiments, the second scraper 309 described above can be made of flexible material, so that one end of the second scraper 309 can be fixedly connected with the first scraper 308. When working, if the end of the second scraper 309 touches the inner wall of the silo and is bent and deformed, it can also play a role in preventing damage to the silo or the device itself.

[0040] In some embodiments, as shown in Figure 5 and Figure 6 The inner sleeve 1 comprises a first telescopic cylinder 101 and a second telescopic cylinder 102 that are nested together and telescopically and lockably connected, the first telescopic cylinder 101 is located below the second telescopic cylinder 102, and by adjusting the position of the first telescopic cylinder 101, the size of the air return gap H between the lower end of the inner sleeve 1 and the lower end of the outer sleeve 2 can be adjusted to an appropriate height, thereby achieving a higher material suction efficiency.

[0041] In order to facilitate the operation of the height position of the first telescopic cylinder 101 on the outside of the outer sleeve 2, an operating portion 103 is arranged on the outside of the first telescopic cylinder 101, which extends radially outward and passes through a long groove portion 107 vertically extending on the outer sleeve 2 to the outside of the outer sleeve 2. The operating portion 103 comprises a protruding portion 108 formed on the outside of the first telescopic cylinder 101 and extending radially outward to approach the inner wall of the outer sleeve 2, and a handle 109 connected with the protruding portion 108 from the outside of the outer sleeve 2 through the long groove portion 107. Preferably, a locking nut 104 is arranged on the handle 109, and by tightening the locking nut 104, the operating portion 103 and the outer sleeve 2 can be fixed, thereby fixing the relative position between the first telescopic cylinder 101 and the outer sleeve 2 at a suitable position.

[0042] In some embodiments, a cover plate 105 is arranged on the outside of the long groove portion 107 to close the long groove portion 107, and the cover plate 105 can move up and down with the operating portion 103, thereby preventing air flow in the annular space 201 from leaking to the outside.

[0043] The closed material suction device can work in an overall lifting manner. For example, as shown in Figure 7As shown, the closed suction device can include a support frame 7, through which the closed suction device is supported in a liftable state, so that the closed suction device can be lowered in height as the distiller's grains in the ground cylinder are reduced, continuously work, or be raised or shifted as needed. The support frame 7 and the closed suction device can be connected by a hydraulic cylinder or a chain transmission mechanism to drive the closed suction device to lift. When connected by a chain transmission mechanism, a worm gear reduction motor can be used for driving, specifically, a worm gear reduction motor can be used to drive a sprocket to rotate, and the chain is fixed on the closed suction device, so as to realize the lifting of the closed suction device. The above-mentioned support frame 7 can also move along the guide rail perpendicular to the paper surface, so as to be able to suck the distiller's grains and other materials from multiple ground cylinders.

[0044] The closed suction device of the present application is described in detail with reference to the preferred technical solutions of the present application. However, it should be noted that any modification, modification and change can be made by those skilled in the art on the basis of the above disclosure without departing from the spirit of the present application. The present application includes the above specific embodiments and any equivalent form thereof.
