It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0027] Embodiment 1, as Figures 1-5 shown, the present utility model provides a concentrate screening device for gold smelting, including a support mechanism 1. A screening mechanism 2 is fixedly connected to the top of the support mechanism 1, and a cleaning mechanism 3 is fixedly connected to the top of the screening mechanism 2;

[0028] The screening mechanism 2 includes a screening box body 201. A feed hopper 202 is fixedly communicated with the top of the screening box body 201. A first screening plate 203 is fixedly installed on the inner wall of the screening box body 201. A second screening plate 204 is fixedly installed on the inner wall of the screening box body 201. A third screening plate 205 is fixedly installed on the inner wall of the screening box body 201. A fourth screening plate 206 is fixedly installed on the inner wall of the screening box body 201. A fifth screening plate 207 is fixedly installed on the inner wall of the screening box body 201. A set of first screening holes 208 are opened at the tops of the first screening plate 203 and the third screening plate 205. A set of second screening holes 209 are opened at the tops of the second screening plate 204 and the fourth screening plate 206. A set of third screening holes 210 are opened at the top of the fifth screening plate 207. A first guiding plate 211 is fixedly connected to the top of the second screening plate 204. A second guiding plate 212 is fixedly connected to the top of the third screening plate 205. A third guiding plate 213 is fixedly connected to the top of the fourth screening plate 206. A fourth guiding plate 214 is fixedly connected to the top of the fifth screening plate 207. A first discharge hopper 215 is fixedly communicated with one side of the outer wall of the screening box body 201. A second discharge hopper 216 is fixedly communicated with the other side of the outer wall of the screening box body 201. A third discharge hopper 217 is fixedly communicated with the other side of the outer wall of the screening box body 201. A water outlet pipe 218 is fixedly communicated with the other side of the outer wall of the screening box body 201. Two vibration motors 219 are fixedly installed on the outer surface of the screening box body 201.

[0029] The effect achieved by the entire Example 1 is as follows. First, the concentrate is introduced into the feed hopper 202. Due to the action of gravity, the concentrate falls onto the first screening plate 203. Then, two vibration motors 219 are started. The vibration generated by the two vibration motors 219 causes the screening box body 201 to vibrate, thereby increasing the fluidity of the concentrate. A set of first screening holes 208 are opened at the top of the first screening plate 203. The set of first screening holes 208 are used to initially screen out larger and smaller concentrates. The larger concentrates slide down along the top of the first screening plate 203 and finally fall onto the top of the third screening plate 205, while the smaller concentrates and impurities pass through the first screening holes 208 and fall into the second screening plate 204. Since the screening holes at the top of the third screening plate 205 are the same size as the screening holes at the top of the first screening plate 203, the concentrates falling from the top of the third screening plate 205 will be screened again to further separate out smaller concentrates and impurities, while the larger concentrates are discharged by the first discharge hopper 215. A set of second screening holes 209 are opened at the top of the second screening plate 204. The set of second screening holes 209 are responsible for screening the smaller concentrates and impurities falling from the first screening plate 203. After the smaller impurities pass through the second screening holes 209, they fall onto the top of the third screening plate 205 and finally fall through the third screening plate 205 into the fourth screening plate 206, while the larger concentrates that do not pass through the second screening holes 209 fall onto the fourth screening plate 206 under the action of the first guide plate 211. Under the repeated screening of a set of second screening holes 209 at the top of the fourth screening plate 206, the smaller concentrates and impurities pass through the second screening holes 209 and fall onto the fifth screening plate 207, while the concentrates of appropriate size are discharged from the equipment through the second discharge hopper 216. A set of third screening holes 210 are opened at the top of the fifth screening plate 207. Finally, under the screening of the set of third screening holes 210, the smaller concentrates are discharged by the third discharge hopper 217, and the impurities fall to the bottom of the box body. Through this series of multi-stage screenings, the efficient and precise separation of the concentrate is ensured, meeting different particle size requirements.

[0030] Example 2 is as Figures 2-5As shown in the figure, the support mechanism 1 includes a bottom plate 101. Four damping shock absorbers 102 are fixedly installed on the top of the bottom plate 101. A support frame 103 is fixedly installed between the tops of the four damping shock absorbers 102. Four vibration springs 104 are fixedly installed on the top of the support frame 103. Linkage blocks 105 are fixedly installed on the tops of the four vibration springs 104. The cleaning mechanism 3 includes a water tank 301. The output end of the water tank 301 is fixedly communicated with a connecting pipe 302. The output end of the connecting pipe 302 is fixedly communicated with a water pump 303. The output end of the water pump 303 is fixedly communicated with a delivery pipe 304. The output end of the delivery pipe 304 is fixedly communicated with four spray pipes 305. A group of nozzles 306 are fixedly communicated with the output ends of the four spray pipes 305. A connecting plate 307 is fixedly sleeved between the outer surfaces of the four groups of nozzles 306. The top of the bottom plate 101 is fixedly connected to the bottom of the water tank 301. The top of the bottom plate 101 is fixedly connected to the bottom of the water pump 303. The outer side of one wall of the four linkage blocks 105 is fixedly connected to the outer surface of the screening box body 201. The top of the screening box body 201 is fixedly connected to the bottom of the four connecting plates 307.

[0031] The effect achieved by the entire Embodiment 2 is that when it is necessary to clean the concentrate, the staff starts the water pump 303. After the water pump 303 is started, its input end sucks the water inside the water tank 301, and the output end of the water pump 303 pressurizes the water, so that the water flows into the four spray pipes 305 through the delivery pipe 304. Since a group of nozzles 306 are fixedly communicated with the bottoms of the four spray pipes 305, under the action of the nozzles 306, the cleaning water can fully cover the concentrate and the equipment. The sewage after cleaning finally drains out of the equipment through the water outlet pipe 218, completing the cleaning treatment of the concentrate and the equipment.

[0032] Working principle: When concentrate screening is required, the concentrate first falls from the feed hopper 202 to the top of the first screening plate 203. Subsequently, two vibration motors 219 are started. After the vibration motors 219 are started, vibration is generated, which promotes the better flow of the concentrate in the screening box body 201. A set of first screening holes 208 are provided at the top of the first screening plate 203. The set of first screening holes 208 are used for the preliminary screening of larger and smaller concentrates. After the larger concentrates pass through the first screening plate 203, they fall onto the third screening plate 205, while the smaller concentrates and impurities pass through the first screening holes 208 and fall onto the second screening plate 204. The screening holes at the top of the third screening plate 205 are the same size as the screening holes at the top of the first screening plate 203. Therefore, the concentrates falling from the top of the first screening plate 203 will be screened again to further separate the smaller concentrates and impurities, while the larger concentrates are discharged by the first discharge hopper 215. A set of second screening holes 209 at the top of the second screening plate 204 are responsible for screening the concentrates and impurities again. After the smaller impurities pass through the second screening holes 209, they fall onto the third screening plate 205 and finally fall through the third screening plate 205 onto the fourth screening plate. The concentrates that do not pass through the second screening holes 209 fall onto the fourth screening plate 206 under the action of the first guide plate 211. After being screened again by a set of second screening holes 209 at the top of the fourth screening plate 206, the smaller concentrates and impurities will pass through the second screening holes 209 and fall onto the fifth screening plate 207. The medium-sized concentrates are discharged from the equipment through the second discharge hopper 216. Finally, under the screening of the fifth screening plate 207, the smaller concentrates are discharged by the third discharge hopper 217, while the impurities fall to the bottom of the screening box body 201. When the concentrate or the equipment needs to be cleaned, the staff can turn on the water pump 303. After the water pump 303 starts working, it sucks water from the water tank 301, pressurizes it, and the pressurized water flows through the delivery pipe 304 to the four spray pipes 305. Since the bottoms of the four spray pipes 305 are fixedly connected to four groups of nozzles 306, the high-pressure water can be evenly sprayed from the nozzles 306 to achieve the comprehensive cleaning of the concentrate and the equipment, and the sewage after cleaning can be discharged from the equipment through the water outlet pipe 218.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
