For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] The embodiment of the present invention provides a reaction device for producing a zinc sulfide product, see Figure 1 , Figure 2 The reaction device includes a side cover 101, on which a plurality of reaction chambers 102 are evenly and fixedly installed along the length direction. The reaction chamber 102 is a hemispherical shell, the interior of which is used to form a zinc sulfide deposition layer, and a temperature control mechanism is installed on the outside to control the deposition temperature in the reaction chamber 102.

[0024] Among them, the temperature control mechanism can be installed with an electric heating insulation layer to achieve the heating and insulation effect of the reaction chamber 102, or it can be other structures that achieve heating and insulation in the reaction chamber 102, which will not be described in detail here.

[0025] Sealing grooves 105 are fixedly installed on both long sides of the side cover 101, and a first mounting plate 104 is fixed on the outer side of the sealing groove 105. The side cover 101 is fixedly installed on one side of the conveying mechanism 200. The mechanism body composed of the side cover 101, the reaction chamber 102, the first mounting plate 104 and the sealing groove 105 is symmetrically distributed about the center of the conveying mechanism 200.

[0026] The first end of the conveying mechanism 200 is fixedly installed with an outlet end cover 106, which is sleeved on the outer side of the first end of the conveying mechanism 200 installed with two sets of side covers 101, and is used to limit the relative position of the side cover 101 and the conveying mechanism 200, and can completely block the first end of the conveying mechanism 200.

[0027] The middle part of the outlet cover 106 away from the conveying mechanism 200 is fixedly connected to the outlet pipe 107 . The outlet pipe 107 is externally connected to a negative pressure pump for controlling the reaction pressure in the reaction chamber 102 . The side of the outlet cover 106 is fixed to the second mounting plate 108 .

[0028] See also Figure 2 , Figure 3 The second end of the conveying mechanism 200 is fixedly installed with an inlet end cover 109, and an inner cylinder 110 is coaxially fixed inside the inlet end cover 109. An annular gap is formed between the inlet end cover 109 and the inner cylinder 110, and the second end of the conveying mechanism 200 with two groups of side covers 101 can be sleeved in the annular gap. A mixing mechanism 300 is sealed inside the inner cylinder 110, and the mixing mechanism 300 is connected to the inside of the conveying mechanism 200, and is used to fully and evenly mix the gaseous sulfur and gaseous zinc and convey them to the conveying mechanism 200.

[0029] See also Figure 4 , Figure 5 The conveying mechanism 200 includes a side plate 201, and two third mounting plates 202 and two fourth mounting plates 203 are fixed to the outside of the side plate 201. The two third mounting plates 202 are parallel to the long sides of the side plate 201 and are respectively close to the long sides of the side plate 201, and are respectively used to fix and install the two first mounting plates 104. The two fourth mounting plates 203 are parallel to the short sides of the side plate 201 and are respectively close to the short sides of the side plate 201, and are respectively used to fix and install the outlet end cover 106 and the inlet end cover 109.

[0030] Sealing strips 204 are fixed to the two long side surfaces of the side plate 201 , respectively. The sealing strip 204 and the side plate 201 are plugged into the sealing groove 105 . The sealing strip 204 is used to achieve sealing between the side plate 201 and the sealing groove 105 .

[0031] The inner side of the side panel 201 is fixed to the connecting block 205, and the connecting block 205 is fixed to the conveying channel 206. The cross-sectional shape of the conveying channel 206 perpendicular to the long side is a square. The structure composed of the side panel 201, the third mounting plate 202, the fourth mounting plate 203, the sealing strip 204, and the connecting block 205 is symmetrically distributed about the center of the conveying channel 206.

[0032] A plurality of groups of upper conveying parts 210 are evenly and fixedly installed on the upper surface of the conveying channel 206 along its length direction, and a nozzle 230 is rotatably installed on the upper conveying part 210, and the upper conveying part 210 connects the nozzle 230 with the interior of the conveying channel 206. A plurality of groups of lower conveying parts 220 are evenly and fixedly installed on the lower surface of the conveying channel 206 along its length direction, and a nozzle 230 is rotatably installed on the lower conveying part 220, and the lower conveying part 220 connects the nozzle 230 with the interior of the conveying channel 206, and the nozzle 230 is coaxially arranged inside the reaction chamber 102.

[0033] In this embodiment, through the above structure, the reactant gas mixed evenly in the mixing mechanism 300 is first transported to the inside of the delivery channel 206, and a stable negative pressure is formed in the gap cavity surrounded by the delivery channel 206 and the side cover 101 through the negative pressure pump installed on the outlet pipe 107. Driven by the negative pressure, the mixed gas in the delivery channel 206 is transported to the nozzle 230 through the upper delivery part 210 and the lower delivery part 220, and the mixed gas is evenly rotated and sprayed onto the inner surface of the reaction chamber 102 through the nozzle 230. After the mixed gas contacts the inner surface of the reaction chamber 102, it reacts and deposits as a zinc sulfide product.

[0034] As a further explanation of the above embodiments, see Figure 8 The nozzle 230 includes a counterweight head 231, which is hemispherical. An annular through hole 232 is coaxially opened at one end of the plane of the counterweight head 231. The annular through hole 232 is connected to the circular inner cavity 233. The outer side of the circular inner cavity 233 is connected to the annular pipe groove 234. The side of the circular inner cavity 233 away from the annular through hole 232 is connected to the diversion cavity 235. The circular inner cavity 233, the annular pipe groove 234, and the diversion cavity 235 are coaxially opened inside the counterweight head 231.

[0035] The side of the diversion cavity 235 is connected to the outer surface of the counterweight head 231 through a plurality of jet pipes 236 . The jet pipes 236 penetrate the side wall of the counterweight head 231 . The outline of the jet pipes 236 is an arc shape, and all the jet pipes 236 rotate in the same direction.

[0036] The plurality of jet pipes 236 are divided into several layers according to different horizontal heights. The middle layer jet pipes 236 are arranged in the same horizontal plane. The plurality of jet pipes 236 close to the annular through hole 232 are located in a conical surface inclined from the inside to the outside and from the top to the bottom. The plurality of jet pipes 236 away from the annular through hole 232 are located in a conical surface inclined from the inside to the outside and from the bottom to the top.

[0037] The cross-sectional shape of the annular tube groove 234 along its radial direction is a racetrack shape.

[0038] The above-mentioned structure of the nozzle 230 enables the mixed gas in the diversion chamber 235 to be discharged outward through a plurality of injection pipes 236. The recoil force of the gas will push the counterweight head 231 to rotate around the axis of the annular through hole 232, and the injection pipes 236 in different horizontal height layers can evenly distribute the gas inside the reaction chamber 102, thereby ensuring the uniform thickness of the deposition layer.

[0039] See also Figure 6 , Figure 8 The upper conveying part 210 includes a first pipe 211, a first end of the first pipe 211 is fixedly connected to the upper surface of the conveying channel 206, a second end of the first pipe 211 is fixedly connected to the first end of the first neck tube 212, the first neck tube 212 is sealed and rotatably arranged inside the annular through hole 232, the second end of the first neck tube 212 is coaxially fixed and connected to the first annular cavity 213, and the first annular cavity 213 is rotatably arranged inside the circular inner cavity 233.

[0040] The outer surface of the first annular cavity 213 is coaxially fixedly connected to the first annular tube 214, the first annular tube 214 is rotatably arranged in the annular tube groove 234, and the outer surface of the first annular tube 214 is sealed and overlapped with the inner surface of the annular tube groove 234, and a plurality of first through holes 215 are evenly arranged on the top of the first annular tube 214 along the circumferential direction.

[0041] like Figure 6 As shown, the mixed gas located in the conveying channel 206 enters the first annular tube 214 through the first pipe 211, the first neck tube 212, and the first annular cavity 213, and is ejected outward through the first through hole 215 opened at the top of the first annular tube 214. Due to the sealed overlapping relationship between the outer surface of the first annular tube 214 and the inner surface of the annular tube groove 234, the mixed gas will inevitably push the nozzle 230 upward when it is ejected outward through the first through hole 215, so that a gas channel appears between the first annular cavity 213 and the top of the first annular tube 214 and the circular inner cavity 233 and the inner surface of the annular tube groove 234. The mixed gas enters the diversion cavity 235 along the channel, and is then discharged outward through a plurality of injection pipes 236.

[0042] See also Figure 7 , Figure 8 The lower conveying part 220 includes a second pipe 221, a first end of the second pipe 221 is fixedly connected to the lower surface of the conveying channel 206, a second end of the second pipe 221 is fixedly connected to the first end of the second neck tube 222, the second neck tube 222 is sealed and rotatably arranged inside the annular through hole 232, a second end of the second neck tube 222 is coaxially fixed and connected to the second annular cavity 223, and the second annular cavity 223 is rotatably arranged inside the circular inner cavity 233.

[0043] The outer surface of the second annular cavity 223 is coaxially fixedly connected with the second annular tube 224, the second annular tube 224 is rotatably arranged in the annular tube groove 234, and the outer surface of the second annular tube 224 is sealed and overlapped with the inner surface of the annular tube groove 234, a plurality of second through holes 225 are evenly arranged on the top of the second annular tube 224 along the circumferential direction, and a plurality of return pipes 226 are evenly fixed on the second annular cavity 223 along the circumferential direction, and the return pipes 226 connect the bottom and the top of the second annular cavity 223.

[0044] like Figure 7 The mixed gas shown in the delivery channel 206 enters the second annular tube 224 through the second pipe 221, the second neck tube 222, and the second annular cavity 223, and is ejected outward through the second through hole 225 opened at the top of the second annular tube 224. Due to the sealed overlapping relationship between the outer surface of the second annular tube 224 and the inner surface of the annular tube groove 234, the mixed gas will inevitably push the nozzle 230 upward when it is ejected outward through the second through hole 225, so that a gas channel appears between the second annular cavity 223 and the top of the second annular tube 224 and the circular inner cavity 233 and the inner surface of the annular tube groove 234. The mixed gas first enters the inside of the gas channel, and further enters the diversion cavity 235 downward through a plurality of reflux pipes 226, and then is discharged outward through a plurality of injection pipes 236.

[0045] When a gas channel appears between the second annular cavity 223 and the top of the second annular tube 224 and the inner surface of the circular inner cavity 233 and the annular tube groove 234, the nozzle 230 is in a suspended state, thereby greatly reducing the resistance to the rotation of the counterweight head 231, and cooperating with the reaction force of the mixed gas ejected outward through the injection pipe 236, the counterweight head 231 is smoothly driven to rotate.

[0046] In addition, in the above structure, the gravity of the counterweight head 231 itself can effectively maintain the negative pressure formed in the gap cavity surrounded by the conveying channel 206 and the side cover 101. When the pressure difference between the inside and outside of the conveying channel 206 becomes larger, the mixed gas automatically overcomes the gravity of the counterweight head 231 and is discharged outward. When the pressure difference between the inside and outside of the conveying channel 206 becomes smaller, the mixed gas cannot overcome the gravity of the counterweight head 231, and the gas channel is closed.

[0047] By stably maintaining the negative pressure formed in the gap cavity surrounded by the conveying channel 206 and the side cover 101, the reaction conditions of the zinc sulfide product can be optimized, thereby improving the product quality.

[0048] As a further explanation of the above embodiments, see Fig. 9 , Fig.10 The mixing mechanism 300 includes an air inlet chamber 301 , the bottom of which is fixedly connected to a mixing chamber 302 , and the mixing chamber 302 can be sealed and disposed in the inner cylinder 110 .

[0049] Two air inlet pipes 303 are fixedly connected to the side of the air inlet chamber 301, one of the air inlet pipes 303 is used to transport sulfur vapor inside the air inlet chamber 301, and the other air inlet pipe 303 is used to transport zinc vapor inside the air inlet chamber 301. The air inlet chamber 301 is connected to the first end of the U-shaped pipeline 304, the U-shaped pipeline 304 is a U-shaped track, and turbulent parts 310 are alternately arranged on both sides of the path track of the U-shaped pipeline 304, and the turbulent parts 310 are used to complete the mixing of sulfur vapor and zinc vapor.

[0050] The second end of the U-shaped pipeline 304 is fixedly connected to the first end of the reflux chamber 305 , and the second end of the reflux chamber 305 is fixedly connected to the outlet 306 . The outlet 306 is opened in the middle of the mixing chamber 302 .

[0051] Among them, the turbulent section 310 includes a diverter block 311 and a return air duct 312. The angle between the diverter block 311 and the path of the U-shaped pipeline 304 is an acute angle, and the angle between the outlet direction of the return air duct 312 and the traveling direction of the mixed gas in the U-shaped pipeline 304 is an obtuse angle. The structure first diverts the mixed gas flowing on the path of the U-shaped pipeline 304, one part continues to flow along the path of the U-shaped pipeline 304, and the other part flows along the return air duct 312. At the outlet position of the return air duct 312, the diverted mixed gas meets the mixed gas on the path of the U-shaped pipeline 304 and impacts to form turbulence, thereby effectively achieving further mixing of the two gases.

[0052] The outer surface of the mixing chamber 302 is fixedly mounted with 307 , which can be fastened to the inlet end cover 109 by bolts, so that the mixing chamber 302 is sealed in the inner tube 110 , thereby smoothly delivering the evenly mixed reaction gas to the delivery channel 206 .

Obviously, based on the above description, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention.
