Description

Technical Field

[0001] The utility model relates to the technical field of graphite furnace cooling and temperature reduction, in particular to a mobile device for spraying equipment on a graphite furnace. Background Art

[0002] In the prior art, after graphitization is completed, the insulation material inside the graphitization furnace needs to be cooled. Currently, the more common cooling methods include natural cooling and artificial cooling. Natural cooling involves opening the furnace cover and allowing the high-temperature insulation material inside the furnace to cool naturally to room temperature. Although this method is simple and easy to implement, it has the disadvantages of long cooling time, low production efficiency, incomplete internal cooling, and easy impact on product quality. Artificial cooling involves manually sprinkling water from the furnace top. Although this method can shorten the cooling time, it has the disadvantages of high labor intensity and poor working conditions. Utility Model Content

[0003] The technical problem to be solved by the utility model is that when cooling the existing large-scale graphitizing furnace, the natural cooling method has a long cooling cycle and is inconvenient for production, while the artificial watering method consumes more manpower and has poor working conditions.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is a mobile device for a spraying equipment on a graphite furnace, comprising a graphite furnace body, a mobile spraying equipment being provided on the outside of the graphite furnace body, the mobile spraying equipment comprising two support frames, a support plate being fixed on the top of the support frame, two motors being fixed on the upper side of the support plate, a pulley being fixed on the output end of the motor through the support plate, a transmission belt being provided on the outer side of the pulley, a limiting ring being fixed on the outer side of the transmission belt, a tube body fixing structure being provided in the limiting ring, a spray pipe being clamped in the tube body fixing structure, a limiting slide being provided on one side of the support frame, and a limiting rod being provided for sliding in the limiting slide.

[0005] As a further solution of the present invention: the pipe body fixing structure includes a rotating shaft rotatably arranged in a limiting ring sleeve, a connecting plate is fixed at the bottom of the rotating shaft, hoops are fixed on the lower sides of both ends of the connecting plate, the spray pipe clamp is arranged in the hoop, the bottom of the hoop is fixed by a screw, an extension rod is fixed at one end of the connecting plate, a vertical rod is fixed at one end of the extension rod, a ring is fixed at the top of the vertical rod, the ring is sleeved on the outside of the limiting rod, and the restriction of the ring and the limiting rod can prevent the rotating shaft from rotating at will during the rolling of the transmission belt.

[0006] As a further solution of the present invention: the length of the spray pipe is greater than the length of the connecting plate, so that the entire graphite furnace body can be easily covered.

[0007] As a further solution of the present invention, the length of the limiting rod is greater than the maximum diameter of the pulley, which can prevent the collar from separating from the limiting rod.

[0008] As a further solution of the present invention: a plurality of spray ports are provided on the lower side of the spray pipe, and the spray ports are located just above the graphite furnace body to facilitate temperature reduction and cooling.

[0009] As a further solution of the present invention: the motor is electrically connected to an external power supply, and the spray pipe is connected to an external water pump.

[0010] Compared with the prior art, the utility model has the following advantages: the patent adds a mobile spraying device, which can fix the spray pipe and drive the spray pipe to move periodically to cool the entire graphite furnace. There is no need to use manual water spraying for cooling, which saves time and effort and has a higher safety factor. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] The utility model provides a technical solution for solving the existing problems raised in the background technology.

[0019] Combined with attachment Figure 1 、 2 It can be known that the device includes a graphite furnace body 1, a mobile spraying device is provided on the outside of the graphite furnace body 1, and the mobile spraying device includes two support frames 2, a support plate 3 is fixed on the top of the support frame 2, two motors 4 are fixed on the upper side of the support plate 3, a pulley 5 is fixed on the output end of the motor 4 through the support plate 3, a transmission belt 6 is sleeved on the outside of the pulley 5, a limiting ring sleeve 7 is fixed on the outside of the transmission belt 6, a pipe fixing structure 8 is provided in the limiting ring sleeve 7, and a spray pipe 9 is clamped in the pipe fixing structure 8. A limiting slide 2.1 is provided on one side of the support frame 2, and a limiting rod 10 is slidably provided in the limiting slide 2.1; the motor 4 is electrically connected to the external power supply, and the spray pipe 9 is connected to the external water pump;

[0020] Combined with attachment Figure 3 、 4 , it can be seen that the pipe body fixing structure 8 includes a rotating shaft 8.1 rotatably set in the limiting ring sleeve 7, a connecting plate 8.2 is fixed to the bottom of the rotating shaft 8.1, and a hoop 8.3 is fixed to the lower side of both ends of the connecting plate 8.2. The spray pipe 9 is clamped in the hoop 8.3, and the bottom of the hoop 8.3 is fixed by screws. An extension rod 8.4 is fixed to one end of the connecting plate 8.2, a vertical rod 8.5 is fixed to one end of the extension rod 8.4, and a collar 8.6 is fixed to the top of the vertical rod 8.5. The collar 8.6 is sleeved on the limiting ring sleeve 7. The outer side of the positioning rod 10 is restricted by the collar 8.6 and the limiting rod 10, which can prevent the rotating shaft 8.1 from rotating freely during the rolling of the transmission belt 6; the length of the spray pipe 9 is greater than the length of the connecting plate 8.2, which can easily cover the entire graphite furnace body 1; the length of the limiting rod 10 is greater than the maximum diameter of the pulley 5, which can prevent the collar 8.6 from separating from the limiting rod 10; a plurality of spray ports are opened on the lower side of the spray pipe 9, and the spray ports are located directly above the graphite furnace body 1 to facilitate cooling.

[0021] The working principle of this application is as follows: when spray cooling is performed, the spray pipe 9 is first clamped in the hoop 8.3, and the hoop 8.3 is clamped by a screw to fix the position of the spray pipe 9. Then the motor 4 is started to drive the pulley 5 to rotate, thereby driving the transmission belt 6 to roll. During the rolling process, the transmission belt 6 will drive the limiting ring sleeve 7 to move. The movement of the limiting ring sleeve 7 will drive the pipe body fixing structure 8 to make a planar motion. During the movement of the pipe body fixing structure 8, the ring 8.6 will slide on the outside of the limiting rod 10, and the outside of the limiting rod 10 will also move in the limiting slide 2.1, which can prevent the rotating shaft 8.1 from rotating at will during the rolling process of the transmission belt 6. Then the external water pump is started to make several spray ports spray cooling water for cooling.
