Description

Technical Field

[0001] The utility model belongs to the field of mineral processing machinery and devices, and in particular relates to a spiral chute which can prevent wax hanging and clogging. Background Art

[0002] As a key equipment for gravity separation, the spiral chute has the function of separation according to density. During the flow of slurry, wax hanging and blockage of the discharge port are prone to occur, which seriously affects the maximum economic benefit of mineral processing production operation and increases the workload of workers.

[0003] After searching, it was found that a Chinese patent with publication number: CN 216173153 U discloses a spiral chute for preventing blockage. A hollow structure support rod is fixedly set in the middle of the spiral chute, a concentrate outlet is set on the side of the support rod, and a water spray nozzle is set on the upper part, which can reduce the concentration of spiral concentrate and improve the fluidity of the concentrate.

[0004] The spiral chute in the above patent has strong instantaneous indexes of slurry. By reducing the concentration of spiral concentrate and improving the fluidity of concentrate, it is easy to have low concentration and small processing volume, and the effect of improving the wax hanging phenomenon of slurry on the side is poor; in addition, the effect of using the top water spray nozzle to adjust the slurry blockage at the bottom is poor, which seriously affects the work efficiency. Therefore, in order to fully solve a series of problems such as wax hanging and clogging of the discharge port during the flow of slurry, a spiral chute that prevents wax hanging and clogging is proposed. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art in the wax hanging and clogging of spiral chutes, thereby providing a spiral chute which can prevent wax hanging and clogging.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model discloses a spiral chute for preventing wax hanging and clogging, comprising a frame, a feeding mechanism arranged on the upper part of the frame, a center column arranged in the frame and a spiral chute installed on the outer wall of the center column, the inner wall of the frame is fixedly connected to the outer wall of the spiral chute, and a discharge port is provided at the tail end of the spiral chute. It is characterized in that a base is provided at the lower part of the frame, the center of the base is vertically arranged with the fixed column, and also comprises a wax hanging collection groove, an anti-clogging mechanism and a flushing mechanism, the wax hanging collection groove is a U-shaped groove, which is arranged on the groove wall of the spiral chute, the anti-clogging mechanism comprises a motor and a stirring rod electrically connected to the motor, the motor is fixedly installed on the base, and the stirring rod is inserted into the groove wall of the spiral chute above the discharge port at the tail end of the spiral chute.

[0008] The flushing mechanism described in the utility model is composed of a water tank and a connected main water supply pipe, a group of water supply conduits and a plurality of nozzles. The water tank is arranged at the top of the spiral chute, the main water supply pipe is arranged along the central column to the trough wall of the lowest spiral chute, and the plurality of nozzles are respectively arranged on the upper part of the trough wall of each layer of the spiral chute, and are respectively connected to the main water supply pipe through a group of water supply conduits.

[0009] Preferably, the bottom of the spiral chute is circular in shape.

[0010] Preferably, there are 2 or more ore discharge openings.

[0011] The beneficial effects of the present invention are:

[0012] 1. When the high-speed flowing slurry inside the spiral chute is waxed on the side, the nozzle flushes the slurry on the side. The washed slurry enters the U-shaped trough and flows into the tailings, which significantly alleviates the waxing phenomenon of the spiral chute, reduces the occurrence of blockage, and is conducive to achieving stable mineral processing.

[0013] 2. The anti-blocking mechanism inside the spiral chute can stir the area between the chute surface and the discharge port through the stirring rod as needed, and flushing water can achieve the purpose of preventing blockage.

[0014] 3. The spiral chute has a simple structure and is easy to operate. It is easy for operators to understand and accept it, which can greatly improve the accuracy of the operation and effectively improve the subsequent sorting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
