Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a portable cleaning device for an exhaust gas ring pipe. Background Art

[0002] The polysilicon reduction furnace is a crucial equipment in the field of new energy technology. It is mainly used in the production process of polysilicon. The polysilicon reduction furnace is mainly used to heat and melt silicon powder and perform reduction reaction at high temperature.

[0034] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 5 As shown, the utility model discloses a portable cleaning device for an exhaust gas annular pipe, comprising a body 1, which can enter the annular pipe, and the bottom of the body 1 is in an arc shape adapted to the inner bottom surface of the annular pipe. A control system and a camera mechanism 2, a driving mechanism 3, a dust suction mechanism 4, and a cleaning mechanism 5 electrically connected to the control system are arranged in the body 1. After the body 1 enters the annular pipe, it is driven by the driving mechanism 3 to move in the annular pipe. During the movement, the dust suction mechanism 4 dusts the inner bottom surface of the annular pipe, and the cleaning mechanism 5 cleans the inner bottom surface of the annular pipe. The operator can observe the internal situation of the annular pipe through the camera mechanism 2.

[0036] The control system includes an electrically connected battery, a control circuit board and a communication module. The battery is a rechargeable battery and serves as a power source for the device. The communication module can realize remote signal transmission.

[0037] The camera mechanism 2 includes a support 21 arranged on the top of the body 1, and a protective block 23 is provided at the top of the support 21. The protective block 23 is in the shape of a disk with an outer diameter larger than the support 21. A camera 22 electrically connected to the control system is provided on the side wall of the support 21 close to the direction of movement of the device.

[0038] The driving mechanism 3 includes two driving wheels 31 rotatably arranged at the bottom of the machine body 1. A motor (not shown in the figure) is provided in the machine body 1 and is connected to the driving wheels 31 in a transmission manner. A plurality of anti-skid strips 32 made of rubber are arranged at equal intervals on the outer wall of the driving wheels 31. The motor drives the driving wheels 31 to rotate, and the machine body 1 moves in the annular tube. The driving mechanism 3 also includes a universal wheel 33 rotatably arranged at the bottom of the machine body 1. The universal wheel 33 includes a wheel seat and a pulley. The wheel seat is rotatably connected to the bottom of the machine body 1, and the pulley is rotatably arranged on the wheel seat. The universal wheel 33 is located on the side of the two driving wheels 31 close to the moving direction of the machine body 1, and the distance between the universal wheel 33 and the two driving wheels 31 is the same. When the machine body 1 moves, the two driving wheels 31 and the universal wheel 33 support the machine body 1, and the universal wheel 33 can rotate arbitrarily.

[0039] The dust collecting mechanism 4 includes two dust collecting ports 43 arranged on the bottom surface of the machine body 1. A dust sweeping column 41 is rotatably arranged on the bottom surface of the machine body 1 at the side where the two dust collecting ports 43 are far away from each other. A motor (not shown in the figure) is arranged in the machine body 1 at the dust sweeping column 41 to drive the dust sweeping column 41 to rotate. A plurality of dust sweeping strips 42 are arranged on the outer wall of the circumference of the dust sweeping column 41. The dust sweeping strips 42 are arranged obliquely. The end of the dust sweeping strip 42 away from the dust sweeping column 41 is inclined downward, so that most of the dust sweeping strips 42 can contact the inner bottom surface of the ring tube.

[0040] A dust collecting chamber 46 is provided in the machine body 1, and a dust discharge port 44 is provided on the outer wall of the machine body 1 at the side of the dust collecting chamber 46, and a dust shielding net 45 is detachably connected to the dust discharge port 44. A dust suction pipe is connected to the bottom of the dust collecting chamber 46, and two dust suction ports 43 are connected to the dust suction pipe. A dust suction pump 47 is provided on the dust suction pipe. A dust shielding plate 48 is rotatably provided on the bottom surface of the dust collecting chamber 46 at the top of the dust suction pipe. A torsion spring is provided between the dust shielding plate 48 and the dust collecting chamber 46, and the elastic force of the torsion spring causes the dust shielding plate 48 to cover the top of the dust suction pipe. When the dust suction pump 47 sucks, the airflow carrying dust enters from the dust suction port 43, and the airflow breaks through the dust shielding plate 48 and enters the dust collecting chamber 46. The dust is blocked in the dust collecting chamber 46 by the dust shielding net 45, and the airflow is output by the dust shielding net 45. After the dust suction pump 47 stops suction, the dust shield 48 is reset under the elastic force of the torsion spring, and the dust shield 48 covers the top of the dust suction pipe to prevent the dust in the dust collecting chamber 46 from falling into the dust suction pipe. When cleaning the dust, the dust shield net 45 is removed to pour out the dust in the dust collecting chamber 46.

[0041] The cleaning mechanism 5 includes two groups of cleaning units, and the cleaning units include a cleaning disc 514 rotatably arranged at the bottom of the machine body 1, and the cleaning disc 514 is located at the bottom of the machine body 1 on the side of the dust suction port 43 away from the traveling direction of the machine body 1. The cleaning disc 514 is in an arc shape that matches the inner bottom surface of the annular tube, and a cleaning cotton 52 is arranged at the bottom of the cleaning disc 514. A driving shaft 512 is coaxially arranged on the cleaning disc 514, and a disc groove 51 for accommodating the cleaning disc 514 and an axis groove 511 for accommodating the driving shaft 512 are arranged on the bottom surface of the machine body 1 inside the cleaning disc 514.

[0042] The driving shaft 512 has a prism section, and the prism section of the driving shaft 512 is in the shape of a regular hexagonal prism. A retaining ring 513 is provided on the driving shaft 512 at the bottom of the prism section. The retaining ring 513 is in rotational contact with the shaft groove 511. The bottom of the shaft groove 511 has a retaining platform that is convex and cooperates with the retaining ring 513. The rotation of the driving shaft 512 drives the cleaning disc 514 and the cleaning cotton 52 to rotate. The driving shaft 512 descends in the shaft groove 511 until the retaining ring 513 contacts the retaining platform. The driving shaft 512 is at the maximum downward stroke. At this time, the cleaning disc 514 is outside the disc groove 51. The driving shaft 512 rises and drives the cleaning disc 514 to rise and enter the disc groove 51. After the cleaning disc 514 contacts the disc groove 51, the driving shaft 512 is at the maximum upward stroke.

[0043] The outside of the prismatic section of the driving shaft 512 is sleeved with a first bevel gear 516, and a regular hexagonal prism-shaped driving groove adapted to the prismatic section is coaxially provided on the first bevel gear 516. The first bevel gear 516 is sleeved on the prismatic section through the driving groove. The first bevel gear 516 is in sliding contact with the prismatic section. The first bevel gear 516 can drive the prismatic section to rotate. During this process, the prismatic section of the driving shaft 512 can slide axially in the first bevel gear 516.

[0044] The first bevel gear 516 is rotatably connected to the body 1 on the side of the shaft groove 511 to keep the first bevel gear 516 fixed in its axial direction. A second bevel gear 515 that meshes with the first bevel gear 516 is rotatably provided in the body 1 on the side of the first bevel gear 516. The second bevel gear 515 is provided on the side where the two cleaning units are close to each other. A double-axis motor is provided in the body 1 between the second bevel gears 515 of the two cleaning units. The output shafts at both ends of the double-axis motor are respectively connected to the two second bevel gears 515 through couplings.

[0045] The top of the driving shaft 512 is provided with a liquid injection rod 510 for coaxial rotation. The end of the liquid injection rod 510 away from the driving shaft 512 is provided with a push-pull electromagnet 59. The push-pull electromagnet 59 drives the liquid injection rod 510 to slide along its axial direction, and the liquid injection rod 510 drives the driving shaft 512 to slide along its axial direction. The outer wall of the liquid injection rod 510 is a straight prism, and a straight prism-shaped slide groove matching its shape is correspondingly provided in the outer body 1 of the liquid injection rod 510. The liquid injection rod 510 is in sliding contact with the slide groove, and the liquid injection rod 510 is limited by the slide groove, so that the liquid injection rod 510 can only slide along its axial direction but cannot rotate.

[0046] The driving shaft 512 and the injection rod 510 have interconnected pipelines, the injection rod 510 and the driving shaft 512 are rotationally sealed, the cleaning disk 514 has a cavity connected to the internal pipeline of the driving shaft 512, and the bottom of the cleaning disk 514 is evenly covered with multiple liquid holes connected to the cavity.

[0047] A liquid storage box 56 is provided inside the machine body 1, and a liquid injection port 53 connected thereto is provided on the machine body 1 at the top of the liquid storage box 56, and a top cover 54 is provided on the liquid injection port 53. A liquid baffle plate 55 is provided inside the liquid storage box 56 at the lower part of the bottom end of the liquid injection port 53, and the liquid baffle plate 55 is arranged obliquely, and the lower end of the liquid baffle plate 55 is close to the inner wall of the liquid storage box 56 and there is a gap between the two. The cleaning liquid injected from the liquid injection port 53 flows on the liquid baffle plate 55, and then flows into the liquid storage box 56 from the lower end of the liquid baffle plate 55. The setting of the liquid baffle plate 55 prevents the cleaning liquid from flowing too long, resulting in too fast flow velocity at the end, causing impact and splashing. During the movement of the machine body 1, the liquid baffle plate 55 also prevents or reduces the situation where the cleaning liquid overflows to the liquid injection port 53.

[0048] A micro pump 57 is provided in the body 1 at the side of the liquid storage box 56, and the micro pump 57 is connected to the bottom of the liquid storage box 56. The injection rods 510 of the two cleaning units are connected to a liquid infusion hose 58, and the liquid infusion hose is connected to the output end of the micro pump 57. When the micro pump 57 is running, the cleaning liquid in the liquid storage box 56 is pumped into the liquid infusion hoses 58 of the two cleaning units, and the cleaning liquid then enters the cavity in the cleaning disk 514 through the injection rod 510 and the driving shaft 512, and finally the cleaning liquid enters the cleaning cotton 52 through multiple liquid holes to infiltrate it. The cleaning liquid can be water or alcohol.

[0049] When cleaning the annular tube, the machine body 1 is put into the annular tube from one end, and the driving wheel 31 rotates to make the machine body 1 move forward in the annular tube. During the process, the dust suction mechanism 4 and the cleaning mechanism 5 work, and the two dust sweeping columns 41 rotate to drive the dust sweeping strips 42 to sweep the bottom surface of the annular tube, and the dust is bounced up. The dust suction port 43 sucks the dust into the dust collecting chamber 46, and the cleaning liquid is pumped onto the cleaning cotton 52 to make it soaked. The cleaning disk 514 rotates to clean the bottom surface of the annular tube through the cleaning cotton 52. After the machine body 1 moves from one end of the annular tube to the other end, the operator takes out the machine body 1 and makes it move in the opposite direction to clean it again. During the cleaning process of the machine body 1, the push-pull electromagnet 59 is energized to push the cleaning disk 514 out of the disk slot 51. After the machine body 1 stops cleaning, the push-pull electromagnet 59 loses power and resets, and the cleaning disk 514 is pulled back into the disk slot 51 through the injection rod 510 and the drive shaft 512. During the cleaning and moving process in the annular tube, the internal situation of the annular tube can be observed through the camera mechanism 2.

[0050] The utility model can automatically move in the annular tube and perform cleaning operations. The annular tube does not need to be disassembled and reassembled, thereby improving the working efficiency. During the movement of the machine body 1 in the annular tube, the silicon powder accumulated on the bottom surface of the annular tube is automatically vacuumed and cleaned by the cleaning cotton 52.

[0051] The above embodiments are only preferred embodiments of the present utility model and are not limitations on the technical solutions of the present utility model. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present utility model.
