Background

Compound fertilizer meltwater in-line crystallization takes place occasionally, uses the drill rod to clear up after mainly dismantling the pipeline of scale deposit by the manual work at present to meet the elbow position and can't clear up, can only clear up behind the pipeline cutting, weld repair with the kerf position after the clearance again. The cleaning mode has the disadvantages of complex cleaning process, time and labor waste, high working strength and high cleaning cost.

Disclosure of Invention

The invention aims to provide a dredging drill bit for quickly cleaning compound fertilizer melt pipeline crystals, which can quickly clean pipelines and easily clean crystals at elbows, is simple to operate, saves time and labor, reduces the labor intensity of workers and reduces the cleaning cost.

The dredging drill bit for quickly cleaning the pipeline crystals of the compound fertilizer melt comprises a wear-resistant hose, wherein a bowden cable is arranged in the wear-resistant hose, one end of the bowden cable is connected with the drill bit through a drill bit shaft, a drill bit socket is fixedly arranged at the end part of the wear-resistant hose close to one side of the drill bit, the drill bit shaft penetrates through the drill bit socket to be connected with the bowden cable, and a shaft sleeve is arranged between the drill bit shaft and the drill bit socket; the other end of the bowden cable is provided with a standard joint.

When the pipeline is cleaned, the electric hammer is connected with the bowden cable through the standard connector, the electric hammer rotates to drive the bowden cable to rotate, the bowden cable rotates to drive the drill bit to rotate to clean crystals in the pipeline, and the drill bit socket and the wear-resistant hose do not rotate along with the drill bit socket and the wear-resistant hose. Because the bowden cable and the wear-resistant hose are soft, the elbow of the pipeline can be cleaned normally.

Preferably, a steam pipe is additionally arranged in the wear-resistant hose, the steam pipe is tightly attached to the inner wall of the wear-resistant hose, the outlet of the steam pipe is communicated with a steam channel arranged in the drill bit shaft and the drill bit through an inverted L-shaped pipeline arranged in the drill bit socket and a through hole in the shaft sleeve wall, and the outlet of the steam channel is arranged at the head of the drill bit; and a plurality of radial through holes are uniformly distributed on the drill bit shaft in the circumferential direction, and the positions of the radial through holes correspond to the positions of the through holes on the shaft sleeve wall. The steam pipe inlet is arranged at one end, close to the standard joint, of the wear-resistant hose, the steam pipe inlet is connected with a steam supply pipeline, steam enters an inverted L-shaped pipeline arranged in the drill bit socket through the steam pipe, then enters the drill bit shaft and a steam channel in the drill bit through a through hole in the shaft sleeve wall and a radial through hole in the circumferential direction of the drill bit shaft, and finally is discharged through a steam channel outlet to heat crystals in the pipeline, so that the drill bit can clean the crystals more easily and thoroughly. In the rotating process of the drill bit shaft, steam enters the steam channel from the radial through hole corresponding to the through hole of the shaft sleeve wall at present, and because only one through hole is arranged on the shaft sleeve, the steam entering the steam channel cannot be discharged from other radial through holes of the drill bit shaft.

Preferably, a water pipe is additionally arranged in the wear-resistant hose, the water pipe is tightly attached to the inner wall of the wear-resistant hose, and the outlet of the water pipe is arranged on one side of the drill bit socket. The water pipe inlet is arranged at one end, close to the standard connector, of the wear-resistant hose, the water pipe inlet is connected with a water supply pipeline, water flows in through the water pipe and then flows through the drill bit socket, and flows out from one side of the drill bit socket, so that the crystal slurry after cutting is washed and cleaned.

Preferably, the steam channel outlet is arranged on the back of one cutter head of the drill bit. The steam channel outlet is arranged at the head of the cutter, so that the steam can be better exerted, and the back of the cutter can prevent sundries cut by the drill bit cutter from entering the steam channel, so that the smoothness of the steam channel is ensured.

Preferably, the number of the radial through holes in the circumferential direction of the drill bit shaft is 4-8.

Compared with the prior art, the invention has the beneficial effects that:

the pipeline cleaning device is reasonable in structural design, can quickly clean pipelines, can easily clean crystals at the elbow, is simple to operate, saves time and labor, reduces the labor intensity of workers and reduces the cleaning cost; and the steam pipe and the water pipe are added, so that the pipeline is easier and more thorough to clean.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

referring to fig. 1 and 2, the dredging drill bit for rapidly cleaning compound fertilizer melt pipeline crystals comprises a wear-resistant hose 13, wherein a bowstring cable 9 is arranged in the wear-resistant hose 13, one end of the bowstring cable 9 is connected with a drill bit 1 through a drill bit shaft 4, a drill bit socket 6 is fixedly arranged at the end part of the wear-resistant hose 13 close to one side of the drill bit 1, the drill bit shaft 4 penetrates through the drill bit socket 6 to be connected with the bowstring cable 9, and a shaft sleeve 5 is arranged between the drill bit shaft 4 and the drill bit socket 6; the other end of the bowden cable 9 is provided with a standard connector 11.

In this embodiment:

a steam pipe 8 is additionally arranged in the wear-resistant hose 13, the steam pipe 8 is tightly attached to the inner wall of the wear-resistant hose 13, the outlet of the steam pipe 8 is communicated with a steam channel 2 arranged in the drill bit shaft 4 and the drill bit 1 through an inverted L-shaped pipeline 7 arranged in the drill bit socket 6 and a through hole in the wall of the shaft sleeve 5, and the outlet 3 of the steam channel is arranged at the head of the drill bit 1; and a plurality of radial through holes 16 are uniformly distributed on the drill bit shaft 4 in the circumferential direction, and the positions of the radial through holes 16 correspond to the positions of the through holes on the wall of the shaft sleeve 5. The steam pipe inlet 10 is arranged at one end, close to the standard joint 11, of the wear-resistant hose 13, the steam pipe inlet 10 is connected with a steam supply pipeline, steam enters the inverted L-shaped pipeline 7 arranged in the drill bit socket 6 through the steam pipe 8, then enters the drill bit shaft 4 and the steam channel 2 in the drill bit 1 through the through hole in the wall of the shaft sleeve 5 and one radial through hole 16 in the circumferential direction of the drill bit shaft 4 through the inverted L-shaped pipeline 7, and is finally discharged through the steam channel outlet 3 to heat crystals in the pipeline, so that the drill bit 1 can clean the crystals more easily and thoroughly. During the rotation of the drill shaft 4, steam enters the steam channel 2 through the radial through holes 16 corresponding to the through holes on the wall of the shaft sleeve 5, and because only one through hole is arranged on the shaft sleeve 5, the steam entering the steam channel 2 cannot be discharged through other radial through holes 16 of the drill shaft 4.
