DETAILED DESCRIPTION
[0023] See also Figures 1 to 4 In the embodiment of the utility model, a multifunctional overhead crane ash discharge device comprises an ash tank 1 and an overhead crane, a venturi tube 6, a Roots blower 7 and an ash hopper 8 are arranged on the overhead crane, a venturi tube 6 is installed at the bottom of the ash hopper 8 through a feeder, an air inlet end of the venturi tube 6 is connected to the Roots blower 7, and an air outlet end is connected to an ash delivery pipeline 5, an ash discharge connecting pipe 3 is arranged on the top of the ash tank 1, and the ash delivery pipeline 5 is connected to the ash discharge connecting pipe 3 through a connecting assembly 4;
[0024] The connecting assembly 4 includes a mounting seat 401, a driving rod 402 and a clamp 403. The mounting seat 401 is fixedly mounted at one end close to the discharge port of the ash delivery pipeline 5. The mounting seat 401 is mounted with the clamp 403 through the driving rod 402.
[0025] The ash discharge connection pipe 3 is composed of an outer sleeve and an inner sleeve. The inner sleeve is slidably installed in the outer sleeve in a telescopic manner. A lifting lug 19 is installed at the feeding port of the inner sleeve. The overhead crane moves horizontally to extend the clamp 403 to the outside of the inner sleeve and is located at the bottom of the lifting lug 19. The driving rod 402 contracts to drag the clamp 403 to move vertically upward to form a docking with the discharge port of the ash delivery pipeline 5. The overhead crane and the ash delivery pipeline 5 are rigidly connected in the prior art, so the ash discharge pipe of the ash tank 1 is also rigidly connected. In order to improve In order to improve the connection sealing of the pipeline during high ash discharge, the ash discharge pipe is improved into a retractable ash discharge connecting pipe 3, and a connecting component 4 is added to the ash delivery pipeline 5. The caliper 403 is clamped to the outside of the inner sleeve by moving the overhead crane, the overhead crane stops, the driving rod 402 contracts, and the lifting ear 19 is lifted to extend the ash discharge connecting pipe 3, so as to achieve the docking and sealing of the inner sleeve and the ash delivery pipeline 5 to prevent dust from being scattered. This can solve the problems of short ash discharge pipe length, gap in docking, and inability to extend and retract over a long distance.
[0026] As a further solution of the utility model: the driving rod 402 is an electric telescopic rod, one side of the caliper 403 is an opening, the opening width is greater than the diameter of the inner sleeve, and the side of the caliper 403 close to the end can be set to tilt upward at a small angle. When subjected to force, the ear 19 is moved closer to the inside of the caliper 403 to prevent the caliper 403 from detaching from the ear and causing leakage.
[0027] As a further solution of the utility model: the outer sleeve is composed of a pipe body, a compensation pipe 14, a butt joint pipe 15 and a calibration pipe 17. The butt joint pipe 15 is installed at the feed port end of the pipe body through the compensation pipe 14, the calibration pipe 17 is installed at the bottom of the butt joint pipe 15, and the lifting lug 19 is installed on the outside of the butt joint pipe 15. The ash discharge connecting pipe 3 can only meet the needs of up and down extension. However, since the movement of the overhead crane is not precise enough, the caliper 403 often collides with the ash discharge connecting pipe 3, causing the ash discharge connecting pipe 3 to bend and cause damage to the equipment. In order to avoid the above problems, a compensation pipe 14 is added to the pipe body. The compensation pipe 14 is a corrugated pipe. Flange seats are set at both ends of the corrugated pipe. The flange seats are fixed by springs to maintain the shape of the corrugated pipe. The butt joint pipe 15 is in contact with the caliper 403. The caliper 403 touches the butt joint pipe 15 to deform the compensation pipe 14, forming a flexible connection between the pipe body and the butt joint pipe 15 to avoid damage caused by collision.
[0028] As a further solution of the utility model: the inner diameter of the butt joint pipe 15 is larger than the outer diameter of the ash delivery pipeline 5, the ash delivery pipeline 5 can extend to a certain distance from the butt joint pipe 15, the interior of the calibration tube 17 is an inverted cone, the bottom pipe mouth diameter is the same as the diameter of the butt joint pipe 15, and the top pipe mouth diameter of the calibration tube 17 is larger than the diameter of the ash delivery pipeline 5. The butt joint connection method will affect the sealing between the connections, and even deviations may cause blockage problems. Therefore, through the set method, the large diameter pipe is sleeved on the outside of the small diameter pipe for connection, which can not only maintain smooth material discharge, but also ensure the accuracy of the butt joint.
[0029] As a further solution of the utility model: the ash tank 1 is also provided with a dust collection system;
[0030] The dust collection system includes a side dust collection pipeline 9 and a lower dust collection pipeline 11. The side dust collection pipeline 9 is installed on one side of the top of the ash tank 1, and the lower dust collection pipeline 11 is installed at the bottom of the ash tank 1. The side dust collection pipeline 9 and the lower dust collection pipeline 11 are both connected to the dust removal device 10. The dust removal device 10 is provided with a dust outlet pipeline 13 and an exhaust pipeline 12. A dust collection box 18 is installed at the bottom of the ash tank 1. The lower dust collection pipeline 11 is connected to the dust collection box 18. A dust collection hole is provided at the bottom of the dust collection box 18. A track material receiving trolley 2 is provided at the bottom of the ash tank 1. The original dust collection device is integrated with the overhead crane. The original connection mode is changed by docking with the connecting component 4. There is no problem of dust at the connection. Therefore, the dust collection system of the driving crane The system is dismantled and technically modified to be used on the ash tank 1. Dust will still be generated in the ash tank 1 during the ash discharge process. At the same time, dust will also appear when the ash tank 1 discharges ash to the track receiving trolley 2. By modifying the dust collection system to the ash tank 1 and performing upper and lower double-channel dust removal, it is possible not only to prevent the dust from leaking through the ash discharge connecting pipe 3 after the overhead crane finishes discharging ash, but also to absorb the dust when the bottom is discharged to the track receiving trolley 2, effectively improving the workshop environment. The side dust collection pipeline 9 can also keep the ash tank 1 in a slight negative pressure at all times, to prevent the space in the ash tank 1 from shrinking when discharging ash into the ash tank 1, and to prevent the gas from leaking through the inspection port 16 or the gas opening.
[0031] It should be noted that the above embodiments all belong to the same utility model concept, and the description of each embodiment has its own focus. For matters that are not described in detail in some embodiments, reference can be made to the description in other embodiments.
[0032] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
