Description

Technical Field

[0001] This invention relates to the field of industrial washing equipment technology, specifically to centrifugal dehydrators. Background Technology

[0002] The linens with water are dehydrated using a centrifugal dehydrator.

[0003] Traditional centrifugal dewatering machines often use a horizontally placed cylinder structure, and the probability of linens piling up at the feed inlet during material receiving is about 5%.

[0004] There is an urgent need for a dehydration device that can reduce the probability of linens accumulating at the feed inlet. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention provides an inclined dehydration device for a centrifugal dehydrator, which solves at least one of the above-mentioned technical problems.

[0006] The technical solution of the present invention is: an inclined dehydration device for a centrifugal dehydrator, comprising a dehydrator body, the dehydrator body comprising a base and a dehydration cylinder mounted on the base, the dehydration cylinder comprising an inner cylinder and an outer cylinder arranged coaxially, characterized in that it further comprises a shock absorption mechanism;

[0007] The shock absorption mechanism includes an airbag, two front shock absorbers arranged on the left and right, and two rear shock absorbers arranged on the left and right.

[0008] The base is connected to the vibration frame via the airbag, the front shock absorber, and the rear shock absorber;

[0009] The outer cylinder is mounted on the vibration frame via a pivot shaft;

[0010] The vibrating frame is hinged to one end of the hydraulic cylinder, and the other end of the hydraulic cylinder is hinged to the outer cylinder;

[0011] The hinge point between the hydraulic cylinder and the vibrating frame, the hinge point between the hydraulic cylinder and the outer cylinder, and the hinge point between the vibrating frame and the outer cylinder form a triangle.

[0012] During the feeding and dehydration process of the dehydrator body, the feed inlet of the inner cylinder is inclined downward to the bottom of the inner cylinder, and the angle between the central axis of the inner cylinder and the horizontal direction is 12°-17°.

[0013] When the dewatering machine body discharges material, the bottom of the inner cylinder and the feed inlet of the inner cylinder are inclined downwards.

[0014] This invention reduces the probability of linens piling up at the inlet by using an inclined inner cylinder. Because of the inclined inner cylinder, a shock-absorbing mechanism buffers the centrifugal force and off-center load torque generated during rotation.

[0015] More preferably, during the feeding and dewatering process of the dewatering machine body, the feed inlet of the inner cylinder is inclined downward to the bottom of the inner cylinder, and the angle between the central axis of the inner cylinder and the horizontal direction is 15°.

[0016] More preferably, the direction of the inlet of the inner cylinder is taken as the front end of the inner cylinder;

[0017] On the vertical projection plane in the front-to-back direction, the two front shock absorbers are arranged in an outward V-shape.

[0018] On the vertical projection plane in the front-to-back direction, the two rear shock absorbers are arranged in an inward V-shape.

[0019] More preferably, on the vertical projection plane in the left-right direction, the front shock absorber is tilted forward at 15° from top to bottom;

[0020] The rear shock absorber is vertically positioned on the vertical projection plane in the left-right direction.

[0021] More preferably, the vibration frame includes a horizontally arranged horizontal support frame and an inclined frame.

[0022] The inclined frame is equipped with a first mounting base for mounting one end of the front shock absorber, and the base is equipped with a second mounting base for mounting the other end of the front shock absorber.

[0023] A third mounting bracket for mounting one end of the rear shock absorber is installed on the horizontal support frame, and a fourth mounting bracket for mounting the other end of the rear shock absorber is installed on the base.

[0024] More preferably, the tilted frame is tilted forward at 15° from top to bottom.

[0025] More preferably, counterweights are installed at both ends of the vibration frame, and the counterweights are located on the side adjacent to the inclined frame.

[0026] More preferably, four airbags are provided, and the four airbags are respectively installed on the left and right sides of the horizontal support frame.

[0027] More preferably, two of the four airbags adjacent to the inclined frame are arranged adjacent to the counterweight.

[0028] More preferably, the front end of the outer cylinder is provided with a feed inlet extending out of the center of the inclined frame, the feed inlet includes an annular guide tube, and the bottom of the guide tube is provided with a forward-extending extension.

[0029] It facilitates the import of materials.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] 1) The inner and outer cylinders are set at a relative horizontal inclination of 15°, while existing technologies are all set horizontally. Unlike existing horizontally set dewatering devices, materials are more likely to enter the inner cylinder during feeding, and are less likely to accumulate at the inner cylinder opening, thus accommodating more material under the same conditions.

[0032] This optimization addresses the problem of existing centrifugal dewatering machines experiencing material buildup at the inlet, which can cause machine downtime. After optimization, the probability of linens piling up at the inlet has been reduced from 5% to 1%.

[0033] 2) Because there is a certain angle during feeding, setting a certain angle for the inner cylinder will allow the material to enter the inner cylinder more smoothly along with the water flow, preventing the water flow from changing direction and losing power. Furthermore, with a certain angle, the material tends to gather at the bottom of the inner cylinder, making more efficient use of its volume. The inner and outer cylinders are tilted, and the shock absorbers are also tilted at their respective angles to buffer the centrifugal force and off-center load torque generated during rotation.

The shock absorption mechanism includes an airbag 5, two front shock absorbers 6 arranged on the left and right, and two rear shock absorbers 7 arranged on the left and right. The base 1 is connected to a vibration frame 2 through the airbag 5, the front shock absorbers 6, and the rear shock absorbers 7. The outer cylinder 4 is mounted on the vibration frame 2 through a fulcrum shaft 13. The vibrating frame 2 is hinged to one end of the hydraulic cylinder 11, and the other end of the hydraulic cylinder 11 is hinged to the outer cylinder 4. The hinge points of the hydraulic cylinder 11 and the vibrating frame 2, the hydraulic cylinder 11 and the outer cylinder 4, and the vibrating frame 2 and the outer cylinder 4 form a triangle. During the feeding and dewatering process of the dewatering machine body, the feed inlet of the inner cylinder 3 is inclined downwards to the bottom of the inner cylinder 3, and the angle between the central axis of the inner cylinder 3 and the horizontal direction is 12°-17°. During the discharge of the dewatering machine body, the bottom of the inner cylinder 3 is inclined downwards to the feed inlet of the inner cylinder 3. This invention reduces the probability of linens accumulating at the feed inlet by tilting the inner cylinder 3. Because the inner cylinder 3 is tilted, the shock absorption mechanism ensures that the centrifugal force and off-center load torque generated during rotation are buffered.

[0038] During the feeding and dewatering process of the dewatering machine body, the feed inlet of the inner cylinder 3 is inclined downward to the bottom of the inner cylinder 3, and the angle between the central axis of the inner cylinder 3 and the horizontal direction is 15°.

On the vertical projection plane in the left-right direction, the front shock absorbers 6 are tilted forward at 15° from top to bottom; on the vertical projection plane in the left-right direction, the rear shock absorbers 7 are vertically arranged.

[0040] The vibration frame 2 includes a horizontally arranged horizontal support frame and an inclined frame. A first mounting seat 8 for mounting one end of the front shock absorber 6 is installed on the inclined frame, and a second mounting seat 9 for mounting the other end of the front shock absorber 6 is installed on the base 1. A third mounting seat 10 for mounting one end of the rear shock absorber 7 is installed on the horizontal support frame, and a fourth mounting seat for mounting the other end of the rear shock absorber 7 is installed on the base 1. The inclined frame is tilted forward at a 15° angle from top to bottom.

[0041] Counterweights 12 are installed at both ends of the vibration frame 2, with the counterweights 12 located on the side adjacent to the inclined frame. Four airbags 5 are provided, and the four airbags 5 are respectively installed on the left and right sides of the horizontal support frame. The two airbags adjacent to the inclined frame are arranged adjacent to the counterweights.

[0042] The outer cylinder 4 has a feed inlet extending from the center of an inclined frame at its front end. The feed inlet includes an annular guide cylinder, and the bottom of the guide cylinder has a forward-extending extension. This facilitates the introduction of materials.

[0043] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
