The utility model can effectively solve the problems that screw threads are loosened and fall off due to frequent disassembly and assembly of the water spray nozzle, and the water spray nozzle cannot be repeatedly used due to repeated disassembly and assembly, and the water spray nozzle falls off or is slanted due to the fact that large materials on a sieve collide with the water spray nozzle when the large materials are impacted and fall off after the screw threads are loosened, and solves the problem that the time for disassembly and assembly of the water spray nozzle is long.

Description

Technical Field

[0001] The utility model relates to the technical field related to coal washing nozzles, in particular to a quick-disassembly and anti-collision water spray nozzle. Background Art

[0002] In the existing heavy medium coal preparation process, desludging is an important part of heavy medium coal preparation, and the main equipment for desludging is the desludging screen. The effect of the desludging screen directly affects the cost of coal preparation and the quality of the product. Most coal preparation plants in the existing technology use a single-tube or double-row water spray device on the screen. Although this water spray device is basically mature, there are still many problems:

[0003] (1) When replacing the screen plate under the water nozzle, the water nozzles are densely packed and the space is narrow. Each time, the water nozzles need to be disassembled and assembled before the following work can be completed. Repeated disassembly and assembly of the water nozzles will cause the threads on the water nozzles to loosen, and they cannot be disassembled and assembled repeatedly for reuse;

[0004] (2) After multiple disassembly and assembly, the threads become loose and large pieces of material fall onto the screen. As long as they hit the water nozzle, the water nozzle will fall off or be crooked due to loose threads, especially for banana vibrating screens;

[0005] (3) When disassembling and assembling the water nozzle, a wrench is required to screw the water nozzle onto the thread of the water pipe, which takes a long time for maintenance;

[0006] (4) Frequent knocking off of the water nozzles reduces the service life, leading to increased production costs. Utility Model Content

[0007] The utility model aims to provide a quick-disassembly and anti-collision water spray nozzle, which can effectively solve the problems existing in the background technology.

[0008] In order to solve the problems existing in the background technology, it comprises several vibrating screen water pipe joints 2 welded on the vibrating screen water pipe 1 and water spray nozzles 7 corresponding to the water pipe joints 2, the vibrating screen water pipe joints 2 and the water spray nozzles 7 are butt-jointed via a quick-plug joint 3, the quick-plug joint 3 and the vibrating screen water pipe joint 2 are screwed and fixed, and the root of the water spray nozzle 7 extends outward to form a water spray nozzle joint 6 that can be plugged and matched with the quick-plug joint 3;

[0009] The water nozzle joint 6 is a hollow cube structure as a whole. The end of the quick-connect joint 3 extends axially inward to form a square hole that can be plugged into the water nozzle joint 6. A circle of card slots 8 is provided at the root of the water nozzle joint 6. Two mutually symmetrical pin holes 4 are provided at the end of the quick-connect joint 3. A U-shaped pin 5 that can be tightly plugged into the two pin holes 4 is provided between the two pin holes 4. The end of the U-shaped pin 5 passes through the pin hole 4 and is tightly plugged into the water nozzle joint 6.

[0010] The middle part of the water nozzle joint 6 is provided with a plurality of equally spaced rubber ring grooves 9 , each of which is provided with a rubber ring which can be interference fit with the inner wall of the square corrugated hole in the quick-insert joint 3 .

[0011] Due to the adoption of the above technical scheme, the utility model has the following beneficial effects: it can effectively solve the problem of loosening and falling off of threads due to frequent disassembly and assembly of the water spray nozzle, and the problem that it cannot be disassembled and assembled for reuse many times, and the problem that large pieces of material on the screen hit the water spray nozzle when the threads are loosened and fall, causing the water spray nozzle to fall or be crooked, and solves the problem of long working hours when disassembling and assembling the water spray nozzle. It also solves the problem of shutdown processing due to incorrect angle caused by the water spray nozzle falling or being crooked, and solves the big problem of poor media and mud removal effect and production consumption cost caused by distortion or incorrect angle of the water spray nozzle during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0013] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] See also Figure 1This specific embodiment is implemented by adopting the following technical scheme, which comprises a plurality of vibrating screen water pipe joints 2 welded on the vibrating screen water pipe 1 and a water spray nozzle 7 corresponding to the water pipe joint 2, the vibrating screen water pipe joint 2 and the water spray nozzle 7 are butted against each other through a quick plug joint 3, the quick plug joint 3 and the vibrating screen water pipe joint 2 are fixed by screw thread, and the root of the water spray nozzle 7 extends outward to form a water spray nozzle joint 6 which can be plugged with the quick plug joint 3;

[0016] The water nozzle joint 6 is a hollow cube structure as a whole. The end of the quick-connect joint 3 extends axially inward to form a square hole that can be plugged into the water nozzle joint 6. A circle of card slots 8 is provided at the root of the water nozzle joint 6. Two mutually symmetrical pin holes 4 are provided at the end of the quick-connect joint 3. A U-shaped pin 5 that can be tightly plugged into the two pin holes 4 is provided between the two pin holes 4. The end of the U-shaped pin 5 passes through the pin hole 4 and is tightly plugged into the water nozzle joint 6.

[0017] The middle part of the water nozzle joint 6 is provided with a plurality of equally spaced rubber ring grooves 9 , each of which is provided with a rubber ring which can be interference fit with the inner wall of the square corrugated hole in the quick-insert joint 3 .

[0018] The following is a further description of the method and principle of using the technical solution in this specific implementation method in conjunction with the accompanying drawings:

[0019] During installation, it is only necessary to put the rubber ring into the corresponding rubber ring groove 9, then insert it into the quick-plug connector 3, and then insert the U-shaped pin 5 into the pin hole 4, so that it is stuck in the slot 8 to achieve the axial positioning and fixation of the water nozzle 7. Since the entire water nozzle connector 6 is a hollow cube structure as a whole, and the quick-plug connector 3 adopts a square corrugated hole that can be gap-fitted with the water nozzle connector 6, the rotation of the water nozzle 7 in the circumferential direction can be eliminated, thereby avoiding the problem of thread slippage and nozzle angle deflection caused by multiple disassembly and assembly.
