Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall relate to the scope of protection of the present invention.

Referring to fig. 1 and 2, the solid-liquid separation apparatus provided in this embodiment includes a base frame 100, a filter screen 200, a power device 300, and a spiral blade 400, wherein the filter screen 200 and the power device 300 are respectively disposed on the base frame 100, and the spiral blade 400 can receive the driving of the power device 300 and rotate in the filter screen 200.

Referring to fig. 2 and 3, the filter screen 200 of the present embodiment includes a first filter assembly 210 and a second filter assembly 220, wherein the first filter assembly 210 includes a fixing frame 211 and a plurality of fixing discs 212 arranged at intervals along a length direction of the fixing frame 211; the second filter assembly 220 comprises a sliding frame 221 and a plurality of sliding discs 222 arranged at intervals along the length direction of the sliding frame 221, and each sliding disc 222 can be correspondingly inserted between two adjacent fixed discs 212 one by one; and a transmission unit is arranged between the power device 300 and the sliding frame 221, and is driven by the transmission unit, and the sliding frame 221 can be driven by the power device 300 to move along the length direction of the fixed frame 211.

In brief, compared with the conventional apparatus in which a plurality of filter holes are formed in a circular barrel body to allow liquid to flow out through the filter holes, the solid-liquid separation apparatus of the present embodiment has a structure in which a gap between each fixed disk 212 and the adjacent sliding disk 222 forms a passage through which the liquid flows out. In addition, in this embodiment, the sliding disk 222 can slide relative to the fixed disk 212, so that the distance between the sliding disk 222 and the fixed disk 212 can be changed, and by periodically changing the distance between the sliding disk 222 and the fixed disk 212, the solid substance can be better prevented from blocking the fixed disk 212 and the sliding disk 222, so that the liquid and the solid can be sufficiently separated, that is, the solid-liquid separation apparatus provided by this embodiment can have a better solid-liquid separation effect.

In the solid-liquid separation apparatus of the present embodiment, the structures of the base frame 100, the power device 300, the helical blade 400 and other components can all refer to the existing helical solid-liquid separation apparatus, and the detailed structure thereof will not be described in detail in the present embodiment. The difference between the real-time exchange rate solid-liquid separation equipment and the existing spiral solid-liquid separation equipment lies in the structure of the filter screen 200 and the structure arranged aiming at the filter screen 200.

In a specific structure, referring to fig. 3, the fixing frame 211 of this embodiment includes two first connection rods 2111 connected to the outer periphery of each fixing plate 212, and the two first connection rods 2111 are symmetrically disposed at two sides of each fixing plate 212. Two first connecting rods 2111 are fixedly connected to the outer circumference of the cylinder 600, and the connection structure of the first connecting rods 2111 and the cylinder 600 is not shown in this embodiment since it does not affect understanding.

The sliding bracket 221 of the present embodiment includes two second connecting rods 2211 connected to the outer circumference of each sliding plate 222, and the two second connecting rods 2211 are symmetrically arranged at both sides of each sliding plate 222. And a first guide bar 2112 is arranged on the first connecting bar 2111, a second guide bar 2212 is fixedly arranged on the second connecting bar 2211, and a guide hole is arranged on the second guide bar 2212 and can be sleeved on the first guide bar 2112 in a sliding manner, so that the sliding disc 222 can slide relative to the fixed disc 212 and the distance between the fixed disc 212 and the adjacent sliding disc 222 is changed.

In this embodiment, referring to fig. 2, an elastic member 500 is disposed between the sliding frame 221 and the fixing frame 211, and the elastic member 500 applies an elastic pushing force to the sliding frame 221, so that the sliding frame 221 slides in a direction approaching the power device 300 by the elastic pushing force.

In brief, in the solid-liquid separation apparatus of the present embodiment, the power device 300 can push the sliding frame 221 to slide in a direction away from the power device 300, and after the power device 300 stops pushing the sliding frame 221, the elastic member 500 can push the sliding frame 221 in a direction close to the power device 300. By periodically pushing the sliding frame 221 by the power unit 300, the sliding frame 221 can be reciprocated to periodically adjust the distance between the fixed disk 212 and the sliding disk 222.

Referring to fig. 2, the elastic member 500 of the present embodiment is a spring fitted around the first guide bar 2112, and the elastic member abuts between the first guide bar 2112 and the second guide bar 2212. In some embodiments, the elastic member 500 is also a disc spring including several disc springs arranged in a stack.

Referring to fig. 2 and 3, the transmission unit of the present embodiment specifically includes a driving member 410 fixedly secured to the central shaft of the helical blade 400, and the driving member 410 is rotatably abutted to the sliding bracket 221; and a projection 2213 is provided on the carriage 221, the projection 2213 being located on the rotation path of the driver 410.

By providing the protrusion 2213, when the driving member 410 rotates to the protrusion 2213, the driving member 410 pushes the sliding frame 221 to slide away from the power device 300; when the driving member 410 rotates away from the protrusion 2213, the sliding frame 221 is reset by the elastic member 500 until the driving member 410 rotates to the protrusion 2213 next time, and finally the sliding frame 221 can reciprocate.

In this embodiment, the driving member 410 specifically includes a member body fixedly sleeved on the transmission shaft, and balls disposed on a side of the member body opposite to the sliding frame 221, which are not shown in this embodiment since they do not affect understanding.

In this embodiment, the above balls are provided to change the sliding friction between the driving member 410 and the sliding frame 221 into rolling friction, so that the friction between the driving member 410 and the sliding frame 221 can be greatly reduced, and the wear of the driving member 410 and the sliding frame 221 can be reduced.

Referring to fig. 4, the fixed disk 212 of this embodiment is in a shape of a disk, and first blocking pieces 2121 are respectively disposed on two opposite sides of the fixed disk 212, the first blocking pieces 2121 are in a circular ring shape and are coaxially and fixedly connected to the fixed disk 212, and specifically, the first blocking pieces 2121 are small-diameter ends connected to the fixed disk 212. The sliding plate 222 of the present embodiment is also disc-shaped, and second stopping pieces 2221 are respectively disposed on two opposite sides of the sliding plate 222, the second stopping pieces 2221 are also circular and coaxially and fixedly connected to the sliding plate 222, and the second stopping pieces 2221 are also small-diameter ends connected to the sliding plate 222.

Based on the above-described structure, as shown in fig. 4, when the sliding disk 222 slides away from the fixed disk 212 on one side thereof, the large diameter end of the first blocking piece 2121 and the large diameter end of the second blocking piece 2221 are away from each other, and the distance between the first blocking piece 2121 and the second blocking piece 2221 constitutes a passage through which the liquid substance flows out, and when the sliding disk 222 is farthest from the fixed disk 212, the passage formed between the large diameter end of the first blocking piece 2121 and the large diameter end of the second blocking piece 2221 is widest.

When the sliding disk 222 slides to approach the fixed disk 212 on one side thereof, the large diameter end of the first blocking piece 2121 and the large diameter end of the second blocking piece 2221 approach each other until the large diameter end of the first blocking piece 2121 abuts against the large diameter end of the second blocking piece 2221, at this time, as shown in fig. 5, the channel width is zero, but thereafter, the sliding disk 222 can still slide to approach the fixed disk 212 by the deformation of the first blocking piece 2121 and the second blocking piece 2221.

In this embodiment, by providing the first blocking piece 2121 and the second blocking piece 2221, after the first blocking piece 2121 and the second blocking piece 2221 contact with each other, the sliding tray 222 can still be close to the fixed tray 212 by the deformation of the first blocking piece 2121 and the second blocking piece 2221. That is, by providing the first stopper 2121 and the second stopper 2221, the slider tray 222 can be made to have a larger stroke.

If the first stopper 2121 and the second stopper 2221 are not provided, the sliding tray 222 can move only within a range of 2mm from the fixed tray 2120, taking the maximum width of the passage as an example; because the number of the sliding discs 222 and the fixed discs 212 is large, and each sliding disc 222 is controlled to synchronously move within the range of 2120-2mm of the corresponding fixed disc, the requirements on the coaxiality and the planeness of each sliding disc 222 and the fixed disc 212 are high, and the processing and assembling cost of the solid-liquid separation equipment is greatly increased.

By providing the first blocking pieces 2121 and the second blocking pieces 2221, the maximum width of the passage is 2mm, and if the maximum deformation amount of each blocking piece is 4mm, the sliding disc 222 can move within a range of 10mm, which obviously greatly reduces the difficulty in processing and assembling the solid-liquid separation device. Also, the shape of the blocking material can be changed by the deformation of the first and

second stoppers

2121 and 2221, thereby facilitating the detachment of the blocking material.

In conclusion, the filter screen 200 of the solid-liquid separation equipment of the embodiment can avoid the channel from being blocked by periodically adjusting the width of the channel, so that the solid-liquid separation equipment has a better separation effect.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
