The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate preferred embodiments of the invention and together with the description, serve to explain the principles of the invention and not to limit the scope of the invention.
Referring to fig. 1 to 3, the present invention provides an embodiment of a sludge rapid dewatering machine, which includes a dewatering drum 1, a flat plate type solid-liquid separator 2, and a uniform adjusting assembly 3. The flat-plate solid-liquid separator 2 is an existing sludge dewatering device and mainly comprises a machine body 21 and an inclined conveying surface 22, a pipeline, a water collecting tank, a water outlet and other devices are arranged in the machine body 21, and the inclined conveying surface 22 formed by triangular rotors and wedge-shaped sieve bars which are arranged in an array mode is arranged at the top of the machine body 21. The lower end of the inclined conveying surface 22 is positioned at the feeding end of the flat-plate type solid-liquid separator, sludge is pushed forwards on the inclined conveying surface 22 by the triangular rotor to be dehydrated, and extruded liquid is discharged from a water collecting tank and a water discharging opening in the machine body 21. It should be noted that, the specific structure of the flat plate type solid-liquid separator 2 may be slightly different according to different practical situations, for example, the way of driving the triangular rotor to rotate, the arrangement of the pipes, the position of the water outlet, etc., and the present invention does not limit the same.
The dewatering drum 1 is connected with the flat plate type solid-liquid separator 2 for preliminary dewatering of sludge, one end of which is a sludge outlet end, and the specific structure, installation position and other characteristics of the dewatering drum 1 will be described in detail later. Similarly, the rotation mode of the dewatering drum 1 can be flexibly designed according to the actual structure of the flat plate type solid-liquid separator 2, such as chain transmission, gear transmission and the like, and an independent driving motor can be arranged to drive the dewatering drum 1 to rotate. Because the sludge needs to be uniformly spread on the inclined conveying surface 22 to ensure that the flat plate type solid-liquid separator 2 can normally operate, the uniform adjusting component 3 is arranged at the lower end of the inclined conveying surface 22, namely the feeding end of the flat plate type solid-liquid separator 2, and is used for uniformly dispersing the primarily dehydrated sludge along the direction perpendicular to the conveying direction of the inclined conveying surface 22 so as to realize the effective operation of the flat plate type solid-liquid separator 2 and prevent the sludge from being partially accumulated on the inclined conveying surface 22 to cause blockage.
According to the sludge rapid dehydrator, the sludge is pretreated through the dehydration roller 1, partial liquid in the sludge is separated firstly, and the fluidity of the partial liquid is reduced, so that the triangular rotor in the inclined conveying surface 22 can push the sludge more easily, and the sludge can advance on the inclined conveying surface 22 more rapidly.

The sludge treated by the dewatering drum 1 firstly flows into the collecting tank 31 and then uniformly flows into the inclined conveying surface 22 through the plurality of guide teeth 32, so that the effect of uniformly dispersing the sludge is achieved. The collecting groove 31 in this embodiment is disposed on the outer side of a side wall of the machine body 21 where the lower end of the inclined conveying surface 22 is located, so as to facilitate detachment, replacement and cleaning.
Furthermore, the collecting tank 31 in this embodiment is connected to the sludge outlet end of the dewatering drum 1 by a sludge collecting plate 4, which will be described later, i.e. a passage is provided between the dewatering drum 1 and the collecting tank 31 for the sludge to flow through. In practical implementation, the passage may be a solid or a virtual path, for example, the sludge outlet end of the dewatering drum 1 is located above the collecting tank 31, the sludge directly falls into the collecting tank 31, and the path along which the sludge falls may also be regarded as a passage.

The surface of the reciprocating screw rod 34 is provided with two thread grooves with the same thread pitch and opposite rotation directions, and two ends of the two thread grooves are communicated through smooth transition grooves. The sliding block is arranged in the thread groove and can slide along the thread groove without disengaging. The scraper 33 is connected to a slider, and when the reciprocating screw rod 34 rotates, the slider drives the scraper 33 to reciprocate along the thread groove and is kept below the reciprocating screw rod 34 by the gravity action of the scraper 33.
In addition, the rotary driving member in this embodiment is a chain, which is connected to the reciprocating screw rod 34 and the synchronous driving assembly or driving shaft in the flat plate type solid-liquid separator 2, for driving the reciprocating screw rod 34 to rotate. Similar to the dewatering drum 1, the rotation of the reciprocating screw rod 34 can be driven by a chain and a gear connected with a motor driving the triangular rotor in the inclined conveying surface 22 to rotate, or a rotating motor can be separately arranged and fixedly installed on the collecting tank 31, and the actual driving mode can be determined according to the specific structure of the flat-plate solid-liquid separator 2.
It should be noted that the reciprocating screw 34 may be connected to the collecting tank 31 as described in the present embodiment, or may be mounted on the body 21 of the flat plate type solid-liquid separator 2. Further, the reciprocating screw 34 in the present embodiment is only one preferable way to achieve the reciprocating motion of the scraper 33, and actually, other means may be replaced according to specific situations, and other devices may be used as the reciprocating driver. For example, a pneumatic push rod is arranged on the machine body 21, the telescopic direction of the pneumatic push rod is perpendicular to the conveying direction of the inclined conveying surface 22, a scraper 33 is fixedly arranged at the telescopic end of the pneumatic push rod, and the push rod is controlled by a single chip microcomputer to continuously extend and retract so as to realize the reciprocating motion of the scraper 33; for another example, a crank-link mechanism is disposed on a side of the collecting groove 31, a slide rail is disposed on a side of the collecting groove 31 facing the inclined conveying surface 22, and the scraper 33 is connected to the crank-link mechanism and embedded in the slide rail to realize reciprocating motion.

One end of the cylinder 11 is the mud outlet end of the dewatering drum 1, and when the dewatering drum 1 is inclined or horizontally arranged, the internal mud is pushed out from the mud outlet end of the cylinder 11 by the helical blade 12.
