Description

Technical Field

[0001] This invention relates to the field of industrial exhaust gas treatment technology, specifically to a foldable and easily disassembled spray device. Background Technology

[0002] With the promotion of environmental protection concepts, more and more attention is being paid to exhaust gas treatment in industrial production processes. Generally, exhaust gas treatment devices are used to purify exhaust gas, remove toxic and harmful substances and soot from industrial production emissions, and ensure that the treated gas meets emission standards, thereby reducing air pollution.

[0003] Currently, liquid spraying devices commonly used in industrial production inevitably use liquids that are prone to crystallization and clogging of nozzles, or liquids that easily carry impurities and clog nozzles, during exhaust gas dust removal and gas-liquid heat exchange. Since most of these liquid spraying devices use fixed nozzles, this structure is not conducive to cleaning, so workers need to enter the tower to disassemble them manually, which can easily cause safety accidents.

[0004] Therefore, it is necessary to invent a foldable and easily detachable spray device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a foldable and easily disassembled spray device. By pulling the adjusting sleeve on the outside of the main spray pipe, multiple spray branch pipes are supported in an umbrella shape by the bracket. The foldable nozzle assembly is fixed to the annular support plate inside the tower. Spray water, under the action of the circulating pump, passes through the foldable nozzle assembly to form water spray for dust removal or heat exchange with hot steam. When the foldable nozzle assembly becomes blocked, simply pull the adjusting sleeve back to loosen the bracket, and the spray branch pipes will fold together. Then, the device can be disassembled, pumped out, and the blocked pipes cleaned and unblocked, thus solving the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foldable and easily detachable spray device, comprising:

The connecting box is disposed at the bottom end of the main sprinkler pipe. The number of branch sprinkler pipes is set to multiple, and the multiple branch sprinkler pipes are evenly distributed around the outside of the connecting box. The connection between the branch sprinkler pipes and the connecting box is movably sealed by the metal hose connector. The adjusting sleeve is slidably connected to the outside of the main sprinkler pipe, and the adjusting sleeve and the main sprinkler pipe are fixed and limited by a knob bolt.

[0011] The outer side of the adjusting sleeve and the inner wall of the spray pipe are both equipped with ring buckles at the middle section, and a bracket is connected between the corresponding two ring buckles.

[0012] The bottom of the spray pipe is equipped with a spray nozzle, and the number of spray nozzles is set to multiple, which are distributed in a linear array.

[0013] As a preferred embodiment of the present invention, the number of brackets matches the number of spray pipes, and the two ends of the brackets are respectively hinged to the annular buckles on both sides.

[0014] As a preferred embodiment of the present invention, the top end of the main spray pipe is provided with a pipe connector, which is connected to the output end of the second guide pipe.

[0015] The input end of the spray tower is set as a positioning bushing at the center of the cover, and the main spray pipe is matched with the positioning bushing. The top of the side wall of the positioning bushing is threaded with a clamping screw.

[0016] As a preferred embodiment of the present invention, a connecting plate is hinged to the end of the spray pipe away from the metal hose connector, and a threaded hole is provided at the bottom end of the connecting plate, and a snap-fit ​​bolt is threaded into the threaded hole.

[0017] As a preferred embodiment of the present invention, an annular support plate is fixedly connected to the inner wall of the tower, and a plurality of evenly distributed positioning slots are provided on the upper surface of the annular support plate. A protrusion is fixedly connected to the outer end of the positioning slot, and the protrusion matches the snap-fit ​​bolt.

[0018] A permanent magnet pad is provided in the positioning slot, and the permanent magnet pad is magnetically attracted to the connecting plate.

[0019] As a preferred embodiment of the present invention, flat grooves are provided on the top of both sides of the positioning slot, and baffles are hinged in the flat grooves. Torsion springs are sleeved on the hinge shaft between the baffles and the flat grooves, and the two ends of the torsion springs are fixedly installed to the baffles and the annular support plate, respectively.

[0040] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] This invention provides, for example Figure 1-7 The foldable and easily detachable spray device shown includes:

[0042] The spray tower 1 includes a tower body 101 and a cover 102. The cover 102 is detachably installed on the top of the tower body 101. The bottom of the side wall of the tower body 101 is provided with a discharge port 103 and the middle of the side wall of the tower body 101 is provided with an air inlet 104.

[0043] The circulating pump 2 is connected to the first guide pipe 4 between the input end of the circulating pump 2 and the discharge port 103. The output end of the circulating pump 2 is connected to the input end of the spray tower 1, and the circulating pump 2 is used for circulating and supplying spray water in the spray tower 1.

[0044] The foldable nozzle assembly 3 is located inside the tower body 101 and is used for spraying water to remove dust or for heat exchange with hot steam.

[0045] Specifically, the circulating pump 2 circulates the spray water in the spray tower 1, and sends the spray liquid into the foldable nozzle assembly 3 through the second guide pipe 5 for uniform spraying, forming water spray dust removal or heat exchange with hot steam, etc., to achieve the treatment of exhaust gas.

[0046] The further improvement of the foldable sprinkler assembly 3 is as follows: The foldable sprinkler assembly 3 includes a main spray pipe 301, a branch spray pipe 302, a connecting box 303, a metal hose connector 304, and an adjusting sleeve 305. The connecting box 303 is located at the bottom of the main spray pipe 301. The number of branch spray pipes 302 is set to multiple, and the multiple branch spray pipes 302 are evenly distributed around the outside of the connecting box 303. The connection between the branch spray pipes 302 and the connecting box 303 is connected by the metal hose connector 304 in a movable sealing connection. The adjusting sleeve 305 is slidably connected to the outside of the main spray pipe 301, and the adjusting sleeve 305 and the main spray pipe 301 are fixed and limited by the knob bolt 306.

[0047] In the structure, the outer side of the adjusting sleeve 305 and the inner wall of the spray pipe 302 are both equipped with ring buckles 307 at the middle section position, and the corresponding two ring buckles 307 are connected by brackets 308.

[0048] The bottom of the spray pipe 302 in the structure is provided with a spray nozzle 309, and the number of spray nozzles 309 is set to multiple. The multiple spray nozzles 309 are distributed in a linear array, and the spray nozzles 309 have a good atomization effect on the spray liquid.

[0049] Specifically, by pulling the adjusting sleeve 305 on the outside of the main spray pipe 301, multiple spray branch pipes 302 are supported in an umbrella shape by the bracket 308. The foldable nozzle assembly 3 is fixed on the annular support plate 12 inside the tower body 101. Spraying is performed in the unfolded state. When the foldable nozzle assembly 3 becomes blocked, simply pull the adjusting sleeve 305 back to loosen the bracket 308, and the spray branch pipes 302 are folded together. Then, the pipes are disassembled, pumped out, and cleaned to unclog the blocked pipes.

[0050] Furthermore, the above scheme is further defined as follows: the number of supports 308 in the structure matches the number of spray pipes 302, and the two ends of the supports 308 are respectively hinged to the annular buckles 307 on both sides. The supports 308 can move flexibly, have a good support effect, and have a certain degree of toughness.

[0051] Furthermore, the above scheme is further defined as follows: the top of the main spray pipe 301 in the structure is provided with a pipe connector 6, the pipe connector 6 in the structure is connected to the output end of the second guide pipe 5, which facilitates docking and installation, and the connection is sealed by a sealing ring to prevent leakage.

[0052] In the structure, the input end of the spray tower 1 is set as the positioning bushing 7 at the center of the cover 102, and the main spray pipe 301 is matched with the positioning bushing 7. The top of the side wall of the positioning bushing 7 is threaded with a clamping screw 8, which facilitates the installation of the foldable nozzle assembly 3 and improves its stability.

[0053] Furthermore, the above scheme is further defined as follows: a connecting plate 9 is hinged to one end of the spray pipe 302 away from the metal hose connector 304 in the structure. A threaded hole 10 is opened at the bottom end of the connecting plate 9 in the structure, and a snap-fit ​​bolt 11 is threaded inside the threaded hole 10. The height of the snap-fit ​​bolt 11 is adjustable, and the snap-fit ​​bolt 11 is equivalent to the function of a clamping plate.

[0054] To improve the stability of the foldable nozzle assembly 3 in the unfolded state, the following technical improvements are made: An annular support plate 12 is fixedly connected to the inner wall of the tower body 101 in the structure, and a number of evenly distributed positioning slots 121 are opened on the upper surface of the annular support plate 12. A protrusion 122 is fixedly connected to the outer end of the positioning slot 121 in the structure, and the protrusion 122 matches the snap-fit ​​bolt 11. The snap-fit ​​bolt 11 is screwed into the threaded hole 10 so that it cooperates with the protrusion 122 to block it, thereby improving the connection stability of the device. The annular support plate 12 can prevent the foldable nozzle assembly 3 from falling and uses the positioning slots 121 to prevent it from rotating, thereby improving the stability during spraying.

[0055] A permanent magnet pad is provided in the positioning slot 121 of the structure, and the permanent magnet pad is magnetically attracted to the connecting plate 9. The function of the permanent magnet pad is to facilitate the connecting plate 9 to fit into the inside of the positioning slot 121, so as to quickly position and install it.

[0056] To further improve the stability during spraying, the top of both sides of the positioning slot 121 in the above structure is provided with a flat slot, and a baffle 123 is hinged in the flat slot. A torsion spring is sleeved on the hinge shaft between the baffle 123 and the flat slot. The two ends of the torsion spring are fixedly installed to the baffle 123 and the annular support plate 12, respectively. Under the action of the torsion spring, the baffle 123 is initially set horizontally. When the connecting plate 9 moves down into the positioning slot 121, the baffle 123 is pressed down until the bottom of the baffle 123 fits against the positioning slot 121. Under the action of the torsion spring, the baffle 123 rebounds and closes the top of the positioning slot 121, preventing the foldable nozzle assembly 3 from detaching during spraying.

[0057] In the structure, the baffle 123 matches the positioning slot 121, and the number of positioning slots 121 is an integer multiple of the number of spray sub-pipes 302. The number of spray sub-pipes 302 can be selectively adjusted to control the spray volume and facilitate installation.

[0058] Furthermore, the above scheme is further defined as follows: the foldable nozzle assembly 3 in the structure is distributed in an umbrella shape when working, and the angle between the spray pipe 302 and the horizontal plane when it is open is an acute angle, which facilitates uniform spraying and improves treatment efficiency.

[0059] Furthermore, the above solution is further defined as follows: the spray pipe 302 and the metal hose connector 304 are detachably connected in the structure. The spray pipe 302 is detachable, which facilitates the adjustment of the number of spray pipes 302. The end of the metal hose connector 304 has a closing valve, which closes the end of the metal hose connector 304 after the spray pipe 302 is detached.

[0060] The structure has a three-way pipe 13 on the first guide pipe 4, and a guide ball valve is provided inside the three-way pipe 13. The inner diameter of the three-way pipe 13 is controlled by the guide ball valve, thereby controlling the flow direction of the spray liquid and realizing the addition and replacement of the spray liquid.

[0061] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
