Description

Technical Field

[0001] The utility model relates to the technical field of lime kiln feeding, in particular to a vertical lime kiln feeding system. Background Art

[0002] The vertical lime kiln loading system is a crucial step in the soda lime production process, directly impacting the kiln's stable operation and product quality. Currently, most vertical lime kiln loading systems nationwide employ a similar structure and operating principle: a winch drives the hopper of a stone hoist up and down to load the lime.

[0003] In this system, the hopper (the loading portion of the trolley) is the primary component for carrying and transporting lime. It is quite heavy, typically weighing approximately 2.05 tons. A φ59mm diameter bottom shaft is located at the bottom of the hopper, extending through both ends of the hanger. This shaft is the key component connecting the hopper to the hanger. To secure the hopper, five M18 bolts are typically installed on the shaft, securing it to the hanger.

[0004] However, in actual production, the frequent up-and-down motion of the stone crane's hopper places enormous alternating loads on the bottom shaft and its bolts. This repetitive motion and impact loads can easily lead to fatigue and shear fracture in the bolts. Once a bolt breaks, the hopper could suddenly fall from the hanger, causing a serious safety accident.

[0005] A sudden drop of the hopper not only disrupts the stable loading of the lime kiln, leading to production interruptions, but also results in economic losses for the company. More seriously, this sudden drop poses a direct threat to the safety of on-site inspection workers, potentially resulting in casualties. Therefore, addressing the issue of broken bolts at the bottom of the hopper on a stone crane, resulting in the hopper dropping, has become a pressing technical challenge for current vertical lime kiln loading systems.

[0006] In view of the above problems, the utility model proposes an improved vertical lime kiln feeding system, which effectively prevents the breakage of the bolts at the bottom of the hopper of the stone crane by adding reinforcement devices and positioning rods, thereby ensuring the stability and safety of the hopper. Utility Model Content

[0007] The utility model aims to provide a vertical lime kiln feeding system, which effectively prevents the bolts at the bottom of the stone hoisting vehicle hopper from breaking by adding a reinforcing device and a positioning rod, thereby ensuring the stability and safety of the hopper.

[0009] In some embodiments, the reinforcing device includes two reinforcing plates, the top of each reinforcing plate is connected to the side wall of the stone crane hopper, and the bottom of each reinforcing plate is penetrated by the bottom shaft.

[0022] 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 them. 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.

[0023] refer to Figure 1-3 The lifting mechanism that lifts up and down along the track is that lifting gear 2 is fixed on the lifting gear 2, and lifting gear 2, when lifting gear 2 is lowered to the lifting gear 2, is fixed on the lifting gear 2 and is fixed on the lifting gear 2.

[0024] In some embodiments, the reinforcing device 5 includes two reinforcing plates 51. The reinforcing plates 51 can be 10 mm thick square steel plates with high strength and rigidity. The top of the reinforcing plate 51 is connected to the side wall of the stone crane hopper 2 and can be welded and fixed. The bottom of the reinforcing plate 51 is penetrated by a bottom shaft 3 which can be welded and fixed. The force area between the bottom shaft 3 and the stone crane hopper 2 is increased by the reinforcing plate 51, thereby reducing the pressure on the bottom shaft 3 from the stone crane hopper 2, thereby enhancing the connection strength between the bottom shaft 3 and the stone crane hopper 2, thereby avoiding the risk of bolts breaking due to shearing, and ensuring the stability and safety of the stone crane hopper 2 during movement.

[0025] In some embodiments, the hanger 1 can be constructed from two symmetrically arranged fixing plates 11. Fixing plates 11 can be constructed from channel steel to ensure sufficient strength and rigidity. The tops of the two fixing plates 11 are connected by a connecting plate 12. A lifting member 13 is provided on the tops of the connecting plates 12. These lifting members 13 can be two lifting plates fixed to the center of the tops of the connecting plates 12. Each lifting plate has a lifting hole for connecting to a winch or other lifting equipment, thereby driving the movement of the hanger 1.

[0026] In some embodiments, ribs 14 are connected between the top of the fixing plate 11 and both side surfaces of the connecting plate 12. The ribs 14 can be triangular plates or right-angled trapezoidal plates, which can enhance the connection strength between the fixing plate 11 and the connecting plate 12 and enhance the overall rigidity and stability of the hanger 1.

[0027] In some embodiments, two connecting rods 21 are provided through the stone crane hopper 2, and sliding wheels 22 are provided at both ends of the connecting rods 21. The rotation of the sliding wheels 22 can reduce the friction between the stone crane hopper 2 and the limited track during the lifting process, thereby improving the smoothness of the lifting, and then improving the stability of the lifting.

[0028] In some embodiments, a positioning rod 6 is passed through the bottom shaft 3, a stone crane hopper 2 is provided on the top of the positioning rod 6, and a fastening bolt 4 is passed through the positioning rod 6. The positioning rod 6 can be a square rod, which can increase the contact area between the bottom shaft 3 and the stone crane hopper 2, reduce the pressure of the stone crane hopper 2 on the bottom shaft 3, further enhance the connection stability between the bottom shaft 3 and the stone crane hopper 2, and effectively prevent the risk of the hopper falling due to bolt breakage.

[0029] The specific working principle is as follows:

[0030] In actual use, a winch or other lifting equipment is used to connect the hanger 1 through the lifting member 13, and the winch or other lifting equipment is started to drive the hanger 1 to move upward. The stone crane hopper 2 loaded with materials moves upward along the track to a set height and is slowly lifted. At this time, the track is provided with an opening on one side, and the stone crane hopper 2 near the opening is freed from restraint and rotates toward the opening, thereby pouring the material in the stone crane hopper 2 into the lime kiln, thereby realizing the loading of the lime kiln. After the loading is completed, the winch or other lifting equipment is rotated in the opposite direction to make the empty stone crane hopper 2 fall into the track and descend to the initial loading position.

[0031] During the movement and loading process of the stone crane hopper 2, since the bottom shaft 3 and the stone crane hopper 2 are provided with a reinforcing plate 51, the force area between the bottom shaft 3 and the stone crane hopper 2 can be increased, thereby reducing the pressure of the stone crane hopper 2 borne by the bottom shaft 3, thereby enhancing the connection strength between the bottom shaft 3 and the stone crane hopper 2, and thus avoiding the risk of bolts breaking due to shearing, ensuring the stability and safety of the stone crane hopper 2 during movement.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
