[0025] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0026] like Figure 1 As shown, it is a schematic diagram of the structure of a rotary kiln and a spray gun in the prior art. In the zinc oxide rotary kiln, coal powder needs to be sprayed therein. The spray gun 50 includes a coal inlet pipe 52, an air inlet pipe 53 and a spray pipe 51. The coal inlet pipe 52 and the air inlet pipe 53 are both connected to the spray pipe 51. The front end of the spray pipe 51 extends into the rotary kiln 60 to spray coal powder into the coal spraying area 61 in the rotary kiln 60.

[0027] Since the spray gun 50 is heavy, weighing several hundred kilograms, it is usually fixed by hanging it in the air with an iron chain. However, in the actual production process, since the spray gun introduces high-pressure air, the spray gun 50 will shake when spraying coal, resulting in deviation of the landing point of the sprayed coal powder.

[0028] The utility model discloses a rotary kiln spray gun bracket, such as Figure 2 and Figure 3 As shown, it includes a support frame 30, the front end of the support frame 30 is provided with a front end support assembly 10 for supporting the front end of the spray gun nozzle and a rear end support assembly 20 for supporting the rear end of the spray gun nozzle; the front end support assembly 10 includes an arc-shaped support plate 11, the support plate 11 is consistent with the shape of the front end of the spray gun nozzle (that is, consistent with the shape of the bottom surface of the front end of the spray gun nozzle, so that the two are in close contact), and the support plate 11 and the support frame 30 can be raised and lowered; the rear end support assembly 20 includes an L-shaped extension rod 23, the first section of the extension rod 23 is vertically arranged and the top is fixedly connected to the rear end of the spray gun nozzle, and the "vertical arrangement" here refers to being vertically arranged with the spray gun nozzle. The front end of the second section of the extension rod 23 is fixedly connected to the bottom of the first section, and the first section is vertically arranged with the second section, and the rear part of the second section of the extension rod 23 is connected to the support frame 30 in a liftable manner.

[0029] The utility model designs a support frame 30 at the bottom of the spray gun 50 and adds front and rear support components respectively, so as to support the front and rear sections of the spray pipe 51. Combined with the gravity of the spray gun 50 itself, the spray gun 50 can be firmly fixed on the support frame 30, and the angle of the spray gun 50 can be adjusted according to production needs through the liftable support plate.

[0030] In one embodiment, two ear plates parallel to each other and vertically arranged are provided at the bottom of the support plate 11, and the two ear plates are connected to the top end of the first support rod 13 through a pin 12. The bottom end of the first support rod 13 is connected to the first hand-cranked lifter 14, and the first hand-cranked lifter 14 is installed at the bottom of the front end support assembly 10.

[0031] More specifically, the top of the first support rod 13 can be designed to be flat, so as to facilitate opening a hole so that the pin 12 can pass therethrough. By setting the first hand-cranked lifter 14, the height of the first screw 13 can be adjusted to adjust the height of the front end of the nozzle.

[0032] As a specific implementation, the front end support assembly 10 includes two columns arranged in parallel on the left and right sides, the two columns are connected by a crossbeam, and the crossbeam is installed with a first hand-cranked lifter 14. Since the first hand-cranked lifter 14 and the first support rod 13 are both purchased from the market and have a height limit, in order to reach a predetermined height, the installation height of the first hand-cranked lifter 14 is increased by means of columns and crossbeams.

[0033] In one embodiment, extension plates are provided outwardly at both ends of the support plate 11; the top of the column is located on both sides of the spray gun nozzle, and auxiliary support rods 15 are provided inwardly extending from the column, and the auxiliary support rods 15 are used to support the extension plates. By providing the auxiliary support rods 15, the force on the first hand-cranked lifter 14 can be reduced. Moreover, when the first hand-cranked lifter 14 needs to be replaced, the nozzle 51 can also be temporarily supported by the auxiliary support rods 15. The auxiliary support rods 15 and the column are also movable, so that the auxiliary support rods 15 can adjust the height according to the state of the first hand-cranked lifter 14. The movement of the two can be a guide rail or different connecting holes, etc.

[0034] In addition, two oppositely arranged fixing plates 22 are provided at the bottom of the second section of the extension rod 23, and the fixing plates 22 are connected to the top of the second support rod 21 through a fixing pin, and the bottom of the second support rod 21 is connected to the second hand-cranked lifter 23, and the second hand-cranked lifter 23 is fixedly installed at the rear of the support frame 30. Similarly, the rear end height of the nozzle 51 can be adjusted by the second hand-cranked lifter 23. At the same time, the combination of the two hand-cranked lifters can increase the adjustment range of the nozzle angle as much as possible.

[0035] Specifically, a strip hole for accommodating a fixing pin is provided on the fixing plate 22, and the length direction of the strip hole is consistent with the direction of the second section. Through the design of the strip hole, a certain amount of moving space can be allowed for the spray gun 50, thereby adjusting the length of the spray gun extending into the rotary kiln.

[0036] In the embodiment of the utility model, the support frame 30 includes a frame body 32, and a counterweight platform 31 is provided at the rear end of the frame body 32. Since the weight of the spray gun 50 is relatively large, and the bracket of the embodiment is mainly used to support the nozzle 51, the force on the front end of the bracket will be greater than the force on the rear end, so heavy objects can be placed on the counterweight platform 31 to ensure the stability of the bracket and avoid accidents.
