Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal mine dust control, in particular to a quick-mounting type spray head. BACKGROUND

[0002] In the process of existing coal mine dust control, dust reduction technology is indispensable, and different forms of dust reduction technology rely on different types of spray heads. In order to ensure atomization effect and improve dust reduction efficiency, the spray hole diameter is generally not large, and the internal structure of some spray heads is special. In addition, the water quality of many coal mines is general or poor even after treatment. The dust concentration in the coal mine is high. If the spray head uses these water sources for a long time, it will be easily blocked in such an environment.

[0003] After the spray head is blocked, it is more troublesome to clean and maintain it. It needs to be unscrewed using the corresponding tool, and after cleaning, it needs to be re-wrapped with sealing tape and then screwed back in. It is time-consuming and labor-intensive. On the other hand, impurities such as coal residue, dust and water rust will accumulate inside the spray head during use. Special tools need to be inserted into the internal part of the spray head to wash it. However, the internal structure of some spray heads is complex, such as spiral water inlet core and filter screen. After being used for a period of time, the internal blockage and corrosion of the spray head will cause the spiral water inlet core and the filter screen to be completely blocked and stuck, making it difficult or impossible to disassemble these internal devices for cleaning. As a result, this type of spray head can only be thrown away and replaced, wasting manpower and increasing costs. SUMMARY

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 5 As shown, an embodiment of the present invention provides a quick-install nozzle, which includes a fixing seat 10, an elastic member 60 and a split-petal nozzle 20 formed by splicing a plurality of identical petals 21. The fixing seat 10 is sleeved on the same end of the plurality of petals 21. The same mounting structure is provided between the inner wall of the cavity of the fixing seat 10 and the outer wall of the area where any petal 21 extends into the fixing seat 10. The mounting structure includes a limiting groove 2101 and a limiting protrusion 101 respectively provided on the inner wall of the cavity of the fixing seat 10 and the outer wall of the area where the petal 21 extends into the fixing seat 10. In the direction in which the petal nozzles 20 move away from each other, the limiting groove 2101 first extends at least along the axial direction of the quick-install nozzle and then extends at least along the circumferential direction of the quick-install nozzle. The limiting groove 2101 forms an opening for limiting the insertion of the limiting protrusion 101 at the cavity end of the fixing seat 10 in which it is located or the end of the petal nozzle 20. The limiting protrusion 101 is slidably arranged in the limiting groove 2101. The elastic member 60 is arranged between the fixing seat 10 and the spliced ​​petal nozzle 20. The fixing seat 10 has a water inlet hole 102, and the petal nozzle 20 is spliced ​​to form a water outlet hole 201 connected to the water inlet hole 102.

[0033] In the embodiment, when the split nozzle 20 is installed, the plurality of petals 21 are assembled first, then the elastic member 60 is placed between the fixed seat 10 and the preliminarily assembled split nozzle 20, and the limiting protrusion 101 is aligned with the limiting groove 2101, and then the fixed seat 10 is sleeved from the same end of the plurality of petals 21, the limiting protrusion 101 slides along the limiting groove 2101 and the elastic member 60 is gradually compressed, and since the rear half of the limiting groove 2101 extends at least along the circumference of the quick-mounting nozzle, the movement of the limiting protrusion 101 in the axial direction of the quick-mounting nozzle is stopped by the rear half of the limiting groove 2101 after it moves to the end of the limiting groove 2101, at this time, the fixed seat 10 is loosened, and the fixed seat 10 and the split nozzle 20 will have a relative moving away trend under the action of the elastic member 60, but since the movement of the limiting protrusion 101 under this movement trend is stopped by the rear half of the limiting groove 2101, the two will not be separated, and the quick-mounting nozzle is installed. When the split nozzle 20 is disassembled, only the reverse operation is required (the fixed seat 10 is moved in the opposite direction of the extension of the limiting groove 2101 by artificial control). The split design of the nozzle in the embodiment makes the manufacturing and cleaning and maintenance of the nozzle more convenient, and even if other structures are provided inside the nozzle, the disassembly and cleaning can be performed at a variable speed, and the situation of wasting manpower and material resources due to the internal difficulty in cleaning leading to the necessity of discarding and replacing the nozzle and other waste of manpower and material resources will not occur, which is beneficial to improve the service life of the nozzle. Further, the split nozzle 20 can be machined separately, without the need to insert the machining tool into the cylinder for cutting machining as in the traditional cylindrical nozzle, the machining is easier and more convenient, the difficulty is small, and the machining cost is also not high. On the other hand, the embodiment realizes the assembly limiting of the plurality of petals 21 through the fixed seat 10, and realizes the disassembly of the fixed seat 10 and the plurality of petals 21 through the mounting structure, which is convenient and simple to operate, and saves time and effort.

[0034] Wherein the outer circumference of the fixed seat 10 is a thread segment 106 and a hexagonal segment 107 connected to each other, and the thread segment 106 is located away from the split nozzle 20.

[0035] Specifically, the split spray head 20 formed by splicing the petals 21 is a stepped columnar structure, the fixed seat 10 has a stepped hole section in communication with the water inlet hole 102, the stepped hole section is matched with the stepped columnar structure of the split spray head 20, the split spray head 20 is limitingly installed in the stepped hole section and is spaced from the stepped hole section in the axial direction of the quick-mounting spray head to form a placement cavity, the elastic member 60 is arranged in the placement cavity and the two ends thereof are respectively abutted against the stepped hole section and the split spray head 20, and the limit groove 2101 and the limit protrusion 101 are respectively arranged on the outer wall of the split spray head 20 and the inner wall of the stepped hole section. In this way, the stepped columnar structure of the split spray head is matched with the stepped hole section of the fixed seat to form a stable installation base, and meanwhile, the placement cavity for installing the elastic member 60 is formed in the process of limitingly splicing the fixed seat 10 and the split spray head 20, the necessary installation space is provided for the elastic member 60, the elastic member 60 can play the roles of buffering and resetting during dismounting, and the functionality and installation reliability of the elastic member 60 are ensured.

[0036] Further, the stepped hole section includes a first limiting hole 103 and a second limiting hole 104 in communication with each other, the inner diameters of the water inlet hole 102, the first limiting hole 103 and the second limiting hole 104 increase in turn and penetrate the fixed seat 10, the split spray head 20 further has a through hole 202 in communication with the water outlet hole 201, the water outlet hole 201 and the through hole 202 penetrate the split spray head 20, the lobe body 21 includes a first adapter section 211 and a second adapter section 212 connected with each other, a plurality of first adapter sections 211 are spliced to form a first limiting section 203, a plurality of second adapter sections 212 are spliced to form a second limiting section 204, part of the first limiting section 203 extends into the first limiting hole 103 and is limited and matched with the inner wall of the first limiting hole 103, part of the second limiting section 204 extends into the second limiting hole 104 and is limited and matched with the inner wall of the second limiting hole 104, a limiting groove 2101 is arranged on the outer wall of the second limiting section 204 close to one side of the first limiting section 203, a limiting protrusion 101 is arranged on the inner wall of the second limiting hole 104 away from the water inlet hole 102, the water inlet hole 102, part of the second limiting hole 104, the through hole 202 and the water outlet hole 201 sequentially communicate to form a spray flow channel, one end of the second adapter section 212 extending into the second limiting hole 104 is spaced from the bottom wall of the second limiting hole 104 and forms a placement cavity, the elastic member 60 is sleeved on the outer periphery of the first adapter section 211 and located in the placement cavity, and the two ends of the elastic member 60 respectively abut against the bottom wall of the second limiting hole 104 and the end portion of the second adapter section 212. In this way, by arranging the first limiting hole 103 and the second limiting hole 104, and the first limiting section 203 and the second limiting section 204 matched therewith, a multi-stage limiting structure is constructed, the accurate butt joint and stable fixation between the split spray head 20 and the fixed seat 10 are ensured, and the installation precision of the quick-mounting spray head is improved. Among them, the placement area is surrounded by the side wall and the bottom wall of the second limiting hole 104, the outer peripheral surface of the first limiting section 203 (i.e. the outer peripheral surface of the plurality of first adapter sections 211) and the end surface of the second limiting section 204 facing the first limiting section 203 (i.e. the end surface of the plurality of second adapter sections 212 facing the first adapter section 211), the first limiting hole 103 and the first limiting section 203 are limited and matched, the second limiting hole 104 and the second limiting section 204 are limited and matched, which facilitates the formation of the placement cavity and the installation of the elastic member 60.

[0037] Preferably, the number of lobe bodies 21 in the embodiment is two.

[0038] As Figure 4As shown, the extension shape of the limiting groove 2101 is a hook shape, which includes a guide segment 21011 and an anti-disengagement segment 21012 connected with each other, and the guide segment 21011 and the anti-disengagement segment 21012 both extend along the axial direction and the circumferential arc direction of the quick-mounting nozzle. The limiting protrusion 101 is a clamping bead protrusion, and the end of the guide segment 21011 away from the anti-disengagement segment 21012 forms an opening for limiting the clamping bead protrusion. The extension direction of the anti-disengagement segment 21012 along the circumference of the quick-mounting nozzle is the same as the extension direction of the guide segment 21011 along the circumference of the quick-mounting nozzle, and the extension direction of the anti-disengagement segment 21012 along the axial direction of the quick-mounting nozzle is opposite to the extension direction of the guide segment 21011 along the axial direction of the quick-mounting nozzle. In this way, when the anti-disengagement segment 21012 of the limiting groove 2101 only extends along the circumference, the movement of the limiting protrusion 101 along the anti-disengagement segment 21012 is not limited, and the installation is prone to looseness due to self-sliding or being affected by some factors, which ensures the reliability of the installation. It can be understood that the elastic member 60 is a spring, and the height thereof is high enough, so that when the clamping bead protrusion is located at the end of the limiting groove 2101, the elastic member 60 is still in a compressed state, so as to top the clamping bead protrusion against the end of the limiting groove 2101 and prevent the clamping bead protrusion from being disengaged.

[0039] Specifically, when the quick-mounting nozzle of the present embodiment is installed, as the fixing seat 10 penetrates from one end of the preliminarily spliced split nozzle 20, the second limiting segment 204 will be limited to penetrate into the second limiting hole 104, and the limiting protrusion 101 is aligned and enters the opening of the corresponding limiting groove 2101 in the process. Then, the operator assembles while rotating along the extension direction of the guide segment 21011, and the elastic member 60 is compressed until the limiting protrusion 101 slides to the connection position of the guide segment 21011 and the anti-disengagement segment 21012. At this time, the operator continues to rotate and assemble along the extension direction of the anti-disengagement segment 21012, and the fixing seat 10 and the split nozzle 20 will relatively move away by a distance until the limiting protrusion 101 slides to the end of the anti-disengagement segment 21012, and the installation is completed. At this time, although the elastic member 60 is released to a certain extent, it is still in a compressed state, so it will provide a relatively moving-away force to the fixing seat 10 and the split nozzle 20, but since the position of the limiting protrusion 101 has reached the limit and is stopped, the relative position of the fixing seat 10 and the split nozzle 20 will not change.

[0040] The stepped hole section has a first end surface 1041 for forming a placement cavity at one end in the axial direction of the quick-mounting shower head, and the split shower head 20 has a second end surface 2121 for forming a placement cavity at the other end in the axial direction of the quick-mounting shower head. The first end surface 1041 has a first annular mounting groove 105 for limiting one end of the elastic mounting piece 60, and / or the second end surface 2121 has a second annular mounting groove 205 for limiting the other end of the elastic mounting piece 60. In the case where the second end surface 2121 has the second annular mounting groove 205, any one of the lobe bodies 21 has a first arc-shaped groove 2102 for splicing to form the surface of the second end surface 2121, and a plurality of first arc-shaped grooves 2102 are spliced to form the second annular mounting groove 205. In this embodiment, the first end surface 1041 is the end surface of the second limiting hole 104, and the second end surface 2121 is the end surface of the second limiting section 204. The first end surface 1041 has the first annular mounting groove 105 for limiting one end of the elastic mounting piece 60, and the second end surface 2121 has the second annular mounting groove 205 for limiting the other end of the elastic mounting piece 60, so as to provide an accurate mounting position for the elastic mounting piece 60, ensure the stability and effect of the elastic mounting piece 60 in the working process, facilitate the installation of the elastic mounting piece 60, and avoid the movement of the elastic mounting piece 60.

[0041] As shown in Figure 2 and Figure 3 Any one of the lobe bodies 21 has a second arc-shaped groove 2103 arranged at the outer periphery of the end portion of the stepped hole section, a plurality of second arc-shaped grooves 2103 are spliced to form a third annular mounting groove 206, and the quick-mounting shower head further comprises a sealing rubber ring 31 arranged in the third annular mounting groove 206 and in sealing cooperation with the outer wall of the split shower head 20 and the inner wall of the stepped hole section. In this way, the sealing effect between the split shower head 20 and the fixed seat 10 is ensured, and water entering the first limiting section 203 from the water inlet hole 102 is prevented from leaking from the small gap between the first limiting section 203 of the split shower head 20 and the first limiting hole 103 of the fixed seat 10, which is beneficial to improve the sealing performance of the quick-mounting shower head and reduce resource waste and maintenance costs caused by water leakage.

[0042] It should be noted that the lobe body 21 further comprises an inner convex section 214 arranged on the inner side of the second adapter section 212 away from the first adapter section 211, and a plurality of inner convex sections 214 are spliced to form the water outlet hole 201.

[0043] As shown in Figures 3 to 5As shown, any one of the petals 21 has a sub-hole section 2104 for forming the through hole 202, and the quick-mounting shower head further comprises a sealing rubber strip 32 arranged between any two adjacent petals 21, any one of the petals 21 has a strip-shaped groove 2105 symmetrically arranged on both sides of the sub-hole section 2104, the strip-shaped groove 2105 of any one of the petals 21 is connected with the corresponding strip-shaped groove 2105 of the adjacent petal 21 to form a strip-shaped sealing area, and one sealing rubber strip 32 is arranged in any one of the strip-shaped sealing areas. In this embodiment, the sealing rubber strip 32 is L-shaped, and the strip-shaped groove 2105 on any one of the petals 21 comprises two groove sections, one of which extends along the extension direction of the petal 21 and is located on one side of the sub-hole section 2104, and the other groove section extends in a direction perpendicular to the extension direction of the petal 21 and extends on the inner convex section 214. Through the arrangement of the sealing rubber strip 32, the sealing between the two adjacent petals 21 can be realized, and the sealing performance of the quick-mounting shower head is further improved. It can be understood that the arrangement of the sealing rubber strip 32 will not affect or interfere with the splicing and buckling of the plurality of petals 21, and preferably, the thickness of the sealing rubber strip 32 is twice the depth of the strip-shaped groove 2105.

[0044] As shown in the figure, Figures 2 to 5 The inner wall of the through hole 202 has a clamping groove 2106, and the quick-mounting shower head further comprises a water inlet core 40 provided with a clamping protrusion 401, the water inlet core 40 is clamped in the through hole 202 by the clamping protrusion 401 limitingly installed in the clamping groove 2106, the outer periphery of the water inlet core 40 is limitedly matched with the inner wall of the through hole 202 and separates the through hole 202 into an upper hole section and a lower hole section, the upper hole section is communicated with the water inlet hole 102, the lower hole section is communicated with the water outlet hole 201, and the outer periphery of the water inlet core 40 has a spiral flow channel 402, and the two ends of the spiral flow channel 402 are communicated with the upper hole section and the lower hole section respectively.

[0045] In this embodiment, the water inlet core 40 is limitingly installed in the through hole 202 (the outer diameter of the outer periphery of the main body of the water inlet core 40 is the same as or adapted to the inner diameter of the through hole 202) and is clamped in the through hole 202 by the clamping groove 2106 and the clamping protrusion 401, which facilitates the disassembly and assembly of the water inlet core 40 (the disassembly and assembly of the water inlet core 40 can be realized during the assembly or disassembly of the plurality of petals 21, and the problem of difficult disassembly and assembly of the water inlet core arranged in the integrally formed shower head in the prior art will not occur), and through the design of the spiral flow channel 402, the flow path of the fluid flowing from the upper hole section to the lower hole section (from the water inlet hole 102 to the water outlet hole 201) is changed, so that the water flowing through the spiral flow channel 402 is accelerated after rotation, which is beneficial to improve the spraying efficiency and spraying effect.

[0046] Preferably, at least part of the water inlet hole 102 and / or the water outlet hole 201 is a tapered hole section, so as to improve the guiding effect of the fluid.

[0047] In the embodiment, the part of the water outlet hole 201 away from the through hole 202 is a tapered hole section, which is beneficial to make the sprayed fluid be discharged in a conical shape, so that the spray atomization angle and atomization effect are better.

[0048] Specifically, the clamping protrusion 401 is arranged on the outer periphery of the one end of the water inlet core 40 towards the upper hole section, and the quick-mounting shower head further comprises a filter screen 50, the shape and size of the filter screen 50 are adapted to the cross section of the through hole 202 at the clamping groove 2106, and the filter screen 50 is clamped at the clamping groove 2106 and located at the one end of the water inlet core 40 towards the upper hole section. In this way, the filtration of the fluid for spraying (mainly filtering some large-particle impurities in the water inlet) is realized through the filter screen 50, the self-cleaning capability of the spray system is improved, the maintenance cost is reduced, and the filter screen 50 is arranged in the same way as the water inlet core 40, so that the later disassembly and maintenance are convenient.

[0049] Preferably, the filter screen 50 in the embodiment is made of a steel mesh, the central circular surface diameter of the filter screen 50 is equal to or adapted to the inner diameter of the through hole 202, the two are limitingly matched, the shape of the filter screen 50 is consistent with the top plane of the water inlet core 40, the shape consistency facilitates the placement of the filter screen 50 on the top of the water inlet core 40, and the filter screen 50 can be clamped into the clamping groove 2106.

[0050] As shown in Figure 1 and Figure 4 , at least one set of alignment structures is arranged between any two adjacent petals 21, the alignment structures comprise alignment grooves 2107 and alignment protrusions 213 arranged at the splicing positions of the adjacent two petals 21 respectively, and the alignment protrusions 213 are pluggably arranged in the corresponding alignment grooves 2107. In this way, the alignment and positioning of the petals 21 in the splicing process are ensured, which is beneficial to simplify the assembly process of the split shower head 20, and the design of the alignment structures prevents the misalignment of the petals 21 in the splicing process, thereby ensuring the overall structural integrity and functional consistency of the split shower head 20, and being beneficial to improve the assembly precision and working efficiency.

[0051] In the embodiment, the petals 21 are two, one side of any one petal 21 in the circumferential direction is provided with two alignment protrusions 213 spaced along the axial direction, and the other side is provided with two alignment grooves 2107 spaced along the axial direction and located at the same height as the two alignment protrusions 213 respectively.

[0052] In summary, the application provides a quick-mounting shower head, and the installation process of the quick-mounting shower head comprises:

[0053] The sealing strip 32, the filter screen 50 and the water inlet core 40 are arranged in one of the two half bodies 21, and then the other half body 21 is spliced on the half body 21, and the two half bodies 21 are connected through the alignment structure during the splicing process. After the connection is completed, the split head 20 is obtained, which is internally provided with the sealing strip 32, the filter screen 50 and the water inlet core 40. Then, the fixing seat 10 is installed, and the fixing seat 10 is sleeved from the same end of the plurality of half bodies 21. As the sleeve is deepened, the limiting protrusion 101 slides along the limiting groove 2101, and the elastic element 60 is gradually compressed. Since the rear half of the limiting groove 2101 extends at least along the circumference of the quick-mounting shower head, after the limiting protrusion 101 moves to the end of the limiting groove 2101, the movement of the limiting protrusion 101 in the axial direction of the quick-mounting shower head is stopped by the limiting groove 2101. At this time, the fixing seat 10 is loosened, and the fixing seat 10 and the split head 20 have a relative moving trend under the action of the elastic element 60, but since the movement of the limiting protrusion 101 under this movement trend is stopped by the rear half of the limiting groove 2101, the fixing seat 10 and the split head 20 are not separated from each other, and the quick-mounting shower head is installed.

[0054] When the split head 20 needs to be disassembled for maintenance and cleaning, the reverse operation can be performed (the fixing seat 10 can be manually controlled to move in the reverse direction along the extension direction of the limiting groove 2101), and the internal filter screen 50 and water inlet core 40 can be conveniently disassembled.

[0055] The split head 20 of the quick-mounting shower head of the embodiment is spliced by two half circular half bodies 21. During each processing, the two half circles can be processed respectively, and the processing tool does not need to be inserted into the cylinder for cutting processing like the traditional cylindrical shower head. The processing is more convenient and easier, the processing cost is not high, and further, the filter screen 50 and water inlet core 40 arranged in the split head 20 are more convenient to disassemble, and the impurities, filter screen 50 and water inlet core 40 in the split head 20 can be quickly cleaned and maintained. Through the design and cooperation of the limiting protrusion 101 and the limiting groove 2101 and the combination of the elastic element 60, the fixing seat 10 and the split head 20 are convenient to disassemble and save time and labor. This design avoids the problem that the impurities such as coal cinder and water rust are accumulated in the split head 20 during the use of the traditional shower head, and some of the impurities are even completely blocked and stuck, which is difficult to maintain and clean, and more like disposable products, which need to be replaced by new ones, waste labor and have high use cost. The overall use cost is lower, and the service life is longer.
