Description

Technical Field

[0001] This utility model relates to the field of nozzles, and more particularly to a trickle-flow sewage nozzle. Background Technology

[0002] Sprinklers are the main equipment used for dust suppression, dust reduction, and fire prevention in underground mines. Their purpose is to atomize water or liquid materials such as inhibitors and spray them onto the working face or areas with accumulated coal. However, due to the humid underground environment or special circumstances involving water recycling, impurities easily accumulate in the water flow. Furthermore, due to severe external dust, sprinklers are prone to blockages from the inside out or from the outside in during use or standby, affecting the normal spraying effect and impacting production safety.

[0003] To address the above problems, a self-cleaning trickle-flow sewage nozzle disclosed in Chinese patent CN203380026U can solve these problems to some extent. However, the drawbacks of this device are also obvious. The biggest drawbacks are its poor atomization and unblocking effects. Specifically, the nozzle's spray holes are small holes. Although pressure difference can be used to clear blockages, the hole design results in poor atomization and a small spray area. Furthermore, large particles cannot be discharged through the spray holes, meaning that large particles can still cause blockages. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a trickle discharge nozzle with a simpler structure and better anti-clogging effect.

[0005] The device includes a nozzle body, which is provided with a water inlet and a spray nozzle; the water inlet is used to connect to an external water source, and the spray nozzle is used to atomize and spray water.

[0006] A central shaft is slidably disposed within the inner cavity of the nozzle body, and a water pressure baffle is disposed on the central shaft;

[0007] An energy storage and reset assembly is provided in the nozzle body between the water pressure baffle and the water nozzle;

[0008] A plunger head is provided in front of the central axis, and the plunger head is provided in relation to the water spray nozzle. Water spray channels are uniformly arranged in an array on the wall surface of the plunger head or the water spray nozzle.

[0009] The effect achieved is that, in the standby state, there is no pressure inside the nozzle body, and the central shaft part naturally retracts backward under the action of the elastic force of the energy storage and reset component; a large gap is formed between the water nozzle and the plunger head at the front of the central shaft to avoid dust blockage.

[0010] When in use, water flows into the inner cavity of the nozzle body through the inlet. The pressure in the inner cavity of the nozzle body gradually increases. The water pressure baffle moves forward under the influence of water pressure and compresses the energy storage and reset component. The plunger head part of the central axis gradually fits into the spray nozzle and forms a narrow gap between them, so that the water flows through the spray channel and is atomized and sprayed out in a ring, forming an atomized spray with a very wide spray surface.

[0011] During unblocking, the water pressure is reduced, the water pressure inside the nozzle body decreases, the water pressure baffle moves backward, and the plunger head of the central shaft gradually separates from the spray nozzle, that is, a larger gap is formed between the two again. Impurities accumulated in the nozzle body flow out through the large gap, avoiding nozzle blockage.

[0012] The beneficial effects of this utility model are: This utility model solves a number of problems existing in the sewage nozzles of the prior art. It has better atomization effect, better anti-clogging effect, and can naturally discharge large-diameter blockages. Moreover, the discharge process runs automatically with the opening and closing of the nozzle, without the need for manual intervention. It has lower maintenance frequency, better safety, and greater safety promotion value. Attached Figure Description

[0019] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] Reference Figure 1 , Figure 2 and Figure 3The present invention provides a trickle sewage nozzle, comprising a nozzle body 1, wherein the nozzle body 1 is provided with a water inlet 2 and a water nozzle 3; the water inlet 2 is used to connect to an external water source, and the water nozzle 3 is used to atomize and spray water.

[0021] A central shaft 4 is slidably disposed in the inner cavity of the nozzle body, and a water pressure baffle 41 is disposed on the central shaft 4;

[0022] An energy storage and reset assembly 5 is provided inside the nozzle body 1 between the water pressure baffle 41 and the water nozzle 3.

[0023] A plunger head 42 is provided in front of the central shaft 4. The plunger head 42 is provided in relation to the water nozzle 3. Water spray channels are uniformly arranged in an array on the wall surface of the plunger head 42 or the water nozzle 3.

[0024] Furthermore, the plunger head 42 is circular, conical, T-shaped or other non-standard shape, and the water nozzle 3 is set in a shape corresponding to the plunger head 42. Water spray channels are arranged in a ring array on the outside of the plunger head at the front of the central shaft 4 or on the surface of the water nozzle 3.

[0025] Example 1, refer to the accompanying drawings in the specification. Figure 1 and Figure 3 The nozzle body 1 is in the form of a round tube, with a water inlet 2 at the rear and a front baffle at the front. The water nozzle 3 is centrally located on the front baffle.

[0026] The effect achieved is to optimize the assembly structure and facilitate assembly.

[0027] In Example 2, the inner cavity of the nozzle body 1 includes, from back to front, a connecting pipe section 11, a first variable diameter encapsulation pipe section 12, a second variable diameter encapsulation pipe section 13, an energy storage and reset component encapsulation pipe section 14, and a third variable diameter encapsulation pipe section 15.

[0028] The inner diameter of the first variable diameter encapsulation pipe section 12 is larger than that of the second variable diameter encapsulation pipe section 13; a first water passage plate 16 is provided inside the first variable diameter encapsulation pipe section 12; water passage grooves are uniformly arranged on the first water passage plate 16.

[0029] That is, the water trough plate is fixedly installed in the first variable diameter encapsulation pipe section 12 with the front end of the second variable diameter encapsulation pipe section 13 as the limit and close to its front end.

[0030] The inner diameter of the energy storage and reset component encapsulation tube section 14 is larger than that of the third variable diameter encapsulation tube section 15, and a second water passage plate 17 is provided inside the energy storage and reset component encapsulation tube section 14; water passage grooves are uniformly arranged on the second water passage plate 17.

[0031] The first water passage plate 16 and the second water passage plate 17 are respectively provided with through holes in the center, and the positions of the two through holes are corresponding; the central shaft 4 is slidably disposed in the two through holes.

[0032] The effect achieved is to constrain and limit the displacement stroke of the central axis 4, so that the central axis 4 slides in the center of the nozzle body cavity.

[0033] Example 3. The energy storage and reset component 5 is a spring, and there are two springs in total, including a long spring and a short spring; the long spring is a weak spring and the short spring is a strong spring.

[0034] The effect achieved in this way is that, taking into account the objective fact that the pressure in the water flow chamber gradually increases, when entering the spray state, the first stroke of the central shaft 4 is controlled by the long spring, which means that the water pressure gradually increases. The thrust on the water pressure baffle 41 gradually increases, and the first stroke of the central shaft 4 is controlled by the constraint of the weak spring. The second stroke of the piston is controlled by the synchronous control of the two springs. In other words, this achieves the effect of faster and more stable atomization.

[0035] When the spraying state is disengaged and the unblocking state is entered, the two springs simultaneously push the water pressure baffle 41 to the first stage of backward movement. When the water pressure is extremely low, the long spring alone can push the water pressure baffle 41 to the second stage of backward movement.

[0036] In Example 4, the water pressure baffle 41 is movably disposed inside the energy storage and reset component encapsulation pipe section 14, and its outer diameter is smaller than the inner diameter of the energy storage and reset component encapsulation pipe section 14.

[0037] A spring is provided between the water pressure baffle 41 and the second water passage plate 17, and the spring is sleeved on the central shaft 4.

[0038] The effect achieved in this way is to optimize the assembly structure.

[0039] The working principle of this utility model is:

[0040] In standby mode, there is no pressure inside the nozzle body 1, and the central shaft 4 naturally retracts backward under the action of the spring force; a large gap is formed between the water nozzle 3 and the plunger head 42 at the front of the central shaft 4 to avoid dust blockage.

[0041] In use, water flows into the inner cavity of the nozzle body 1 through the inlet 2. The pressure inside the nozzle body 1 gradually increases, and the water pressure baffle 41 moves forward gradually under the influence of water pressure, compressing the spring. During this process, the first stroke of the central shaft 4 is controlled by the long spring, which means that the water pressure gradually increases. The thrust on the water pressure baffle 41 gradually increases, and the first stroke of the central shaft 4 is controlled by the weak spring. The second stroke of the piston is controlled by the two springs simultaneously. When the water pressure is known to be stable, a single spring that meets the water pressure can also be used to achieve the same effect.

[0042] The plunger head 42 of the central shaft 4 gradually fits into the water nozzle 3, and a narrow gap is formed between them, so that the water flows through the water channel and is atomized and sprayed out in a ring, forming an atomized spray with a very wide spray surface.

[0043] When unblocking, the water pressure is reduced, the water pressure inside the nozzle body 1 decreases, and the two springs simultaneously push the water pressure baffle 41 to the first stage of backward movement. When the water pressure is extremely low, the water pressure baffle 41 can be pushed to the second stage of backward movement by the long spring alone.

[0044] The water pressure baffle 41 moves backward, and the plunger head 42 of the central shaft 4 gradually separates from the spray nozzle 3, that is, a larger gap is formed between the two again. The impurities accumulated in the nozzle body 1 flow out through the large gap to avoid nozzle blockage.
