Description

Technical Field

[0001] The utility model relates to the technical field of lime kilns and is a Maerz lime kiln channel cleaning and drilling hanger. Background Art

[0002] The parallel flow regenerative Maerz lime kiln has two kiln chambers, which alternately calcine and preheat the ore. A connecting channel is installed between the bottoms of the calcining zones of the two kiln chambers to connect them. The direction is reversed every 12-15 minutes to change the working state of the kiln chamber. The burned gas in the calcining chamber and the fine powder produced by the lime are transferred to the regenerative chamber through the connecting channel and are sucked into the dust collector by the induced draft fan. During this process, some of the fine powder sticks to the connecting channel and forms nodules due to the high temperature. This causes high pressure in the connecting channel, thus affecting the production capacity of the lime kiln. Therefore, the kiln needs to be stopped every 75-90 days to clean the connecting channel. During the cleaning process, a 6-meter-long steel chisel is used to knock and clean the nodules. Due to the high temperature during the knocking process, the steel chisel can easily deform and get stuck in the nodules. Currently, when pulling out the steel chisel stuck in the nodule, the operator needs to use an F wrench to pull it out. Not only is the operation labor-intensive and time-consuming, but there is also a risk of burns. Summary of the Invention

[0003] The utility model provides a Maerz lime kiln channel cleaning and drill pulling hanger, which overcomes the shortcomings of the above-mentioned prior art and can effectively solve the problems of high labor intensity and high operation risk for operators when pulling out steel drills stuck in the lime kiln.

[0004] The technical solution of the utility model is achieved through the following measures: a Maerz lime kiln channel cleaning and drill pulling lifting device is used to pull the steel drill out of the lime kiln, comprising a clamping seat, a hoisting hoist and a collar, the clamping seat comprising an upper clamping plate, a lower clamping plate, a connecting plate and a lifting ear, the connecting plate is vertically arranged, the left side of the connecting plate is fixedly connected to an upper clamping plate and a lower clamping plate which are both horizontally arranged and spaced apart from each other, the bottom of the lower clamping plate is fixedly connected to a lifting ear, the hoisting hoist is suspended on the lifting ear by a hook, one end of the chain of the hoisting hoist is fixedly connected to the collar, and the inner diameter of the collar is slightly larger than the diameter of the steel drill.

[0005] The following are further optimizations and / or improvements to the above utility model solution:

[0006] The distance between the upper card plate and the lower card plate can be 3 cm to 5 cm.

[0007] A vertical reinforcing plate may be provided between the top surface of the lower clamping plate and the left side surface of the connecting plate.

[0008] A locking screw hole can be respectively provided on the upper clamping plate at the front and rear sides of the corresponding reinforcing plate, and the locking screw hole is threadedly connected with a locking screw.

[0009] The utility model has a reasonable structure. When in use, the ring is sleeved on the outside of the steel drill, and the other end of the chain of the hoist is fixedly connected to the tractor. The chain of the hoist is pulled by the tractor to pull out the steel drill embedded in the lime kiln. As a result, there is no need for operators to hold an F wrench to manually pull it out. The entire steel drill pulling out operation is simple, convenient and easy to implement, with low labor intensity and low operation risk. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0013] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0014] In this utility model, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 For example, the positional relationships of front, back, up, down, left, and right are determined according to the layout directions of the drawings in the specification.

[0015] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0016] As attached Figure 1-2 As shown, the Maerz lime kiln channel cleaning and drill pulling hanger is used to pull the steel drill 12 out of the lime kiln, which includes a holder, a hoisting hoist 1 and a ring 2. The holder includes an upper clamping plate 3, a lower clamping plate 4, a connecting plate 5 and a lifting ear 6. The connecting plate 5 is vertically arranged. The left side of the connecting plate 5 is fixedly connected to the upper clamping plate 3 and the lower clamping plate 4, which are both horizontally arranged and spaced apart from each other. The bottom of the lower clamping plate 4 is fixedly connected to the lifting ear 6. The hoisting hoist 1 is suspended on the lifting ear 6 by a hook 7. One end of the chain of the hoisting hoist 1 is fixedly connected to the ring 2. The inner diameter of the ring 2 is slightly larger than the diameter of the steel drill 12.

[0017] When in use, the holder is installed on a fixed object, such as the holder is installed on the tensioning plate 11 of the fire hole platform 10 of the kiln body. The tensioning plate 11 is a circular plate. During installation, the upper clamping plate 3 and the lower clamping plate 4 are respectively clamped on the upper and lower sides of the tensioning plate 11, and the ring 2 is set on the outside of the steel drill 12. The other end of the chain of the hoist 1 is fixedly connected to the tractor. The chain of the hoist 1 is pulled by the tractor to pull out the steel drill 12 embedded in the lime kiln. Thereby, there is no need for the operator to hold the F wrench for manual extraction. The entire steel drill extraction operation is simple, convenient, and easy to implement, with low labor intensity and low operation risk. According to requirements, the inner diameter of the ring 2 is 1 mm to 3 mm larger than the diameter of the steel drill 12 to be pulled out.

[0018] The above embodiments may be further optimized and / or improved according to actual needs:

[0019] Specifically, the spacing between the upper card plate 3 and the lower card plate 4 is 3 cm to 5 cm. Specifically, the spacing between the upper card plate 3 and the lower card plate 4 is 5 cm.

[0020] As attached Figure 1-2 As shown, a vertical reinforcing plate 8 is provided between the top surface of the lower card plate 4 and the left side surface of the connecting plate 5. This enhances the structural strength of the card seat.

[0021] As attached Figure 1-2 As shown, the upper clamping plate 3 at the front and rear sides of the corresponding reinforcement plate is provided with a locking screw hole, which is threaded with a locking screw 9. Therefore, when the clamping base is installed on a fixed object such as a ribbed plate 11, the locking screw 9 is tightened to press it against the ribbed plate 11, thereby achieving a fixed connection between the clamping base and the ribbed plate 11 and preventing the clamping base from falling off the ribbed plate 11.

[0022] The above technical features constitute the best embodiment of the present invention, which has strong adaptability and best implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
