[0001] This utility model relates to the field of glass bottle and jar manufacturing technology, specifically to a material lifting device for emergency feeding of kiln silos. Background Technology

[0002] Glass bottles and jars are common containers widely used in industrial production and daily life. For example, glass bottles are commonly used for filling and packaging wine products.

[0003] The molten glass used in glass bottle and jar forming is obtained by adding solid glass raw materials into the kiln through the kiln feeding system for melting. When the kiln system is shut down due to malfunction, maintenance, or other reasons, in order to ensure the continuity of production line, it is necessary to add solid glass raw materials to the kiln head hopper using an emergency feeding device, while ensuring the safe and stable operation of the kiln.

[0004] The existing emergency lifting device is a cylindrical body with an opening at the bottom. During emergency feeding, solid glass raw material is first placed inside the cylinder, then the device is hoisted above the kiln head hopper opening. Workers then open the opening at the bottom of the device to allow the solid glass raw material to fall into the hopper. The existing device is inconvenient to operate, has low feeding efficiency, and the operation of opening the bottom of the device at the high-temperature kiln head hopper opening poses a safety hazard. Furthermore, the device is suspended during feeding, inevitably resulting in swaying and unsatisfactory material drop stability. Utility Model Content

[0008] The cone seat is installed and fixed to the bottom end of the guide rod, and is engaged with the discharge port to block the discharge port; a hook extending above the inlet is installed and fixed to the top end of the guide rod.

[0009] Furthermore, it is also equipped with support arms and linear bearings;

[0010] The linear bearing is fixed to the cylinder via the support arm, and the guide rod is slidably installed inside the linear bearing, forming a kinematic pair with the linear bearing to support the upward or downward movement of the guide rod.

[0011] Furthermore, the linear bearing is installed and fixed to the cylinder by at least two circumferentially distributed support arms.

[0012] Furthermore, at least two linear bearings are provided vertically.

[0013] Furthermore, the bottom of the cavity has a platform-shaped cavity structure with a cross-sectional area decreasing from top to bottom.

[0030] An emergency material lifting device for a kiln silo, such as Figures 1-4 As shown, its structural relationship is as follows: the inside of the cylinder 4 has a cavity, and the top and bottom are respectively opened with a feed port and a discharge port. The discharge port is a platform-shaped opening with a decreasing cross-sectional area from bottom to top.

[0031] It also includes a cone base 1 and a guide rod 5;

[0032] The cone seat 1 is installed and fixed to the bottom end of the guide rod 5, and is fitted into the discharge port to block the discharge port; a hook extending out of the feed port is installed and fixed at the top end of the guide rod 5.

[0033] Preferably, it also includes a support arm 7 and a linear bearing 3;

[0034] The linear bearing 3 is installed and fixed to the cylinder 4 via the support arm 7, and the guide rod 5 is slidably installed inside the linear bearing 3, forming a kinematic pair between the guide rod 5 and the linear bearing 3 to support the upward or downward movement of the guide rod 5.

[0035] The linear bearing 3 and the support arm 7 guide and limit the vertical movement of the guide rod 5 relative to the cylinder 4. While ensuring the radial support strength of the guide rod 5, they do not significantly affect the axial movement of the guide rod 5, thus improving the stability of the guide rod 5 driving the cone seat 1 and enhancing the ease of use of the emergency material lifting device.

[0036] Preferably, the linear bearing 3 is installed and fixed to the cylinder 4 by at least two circumferentially distributed support arms 7.

[0037] In actual installation, it is preferable to have three support arms 7 evenly distributed along the circumference.

[0038] Preferably, at least two linear bearings 3 are arranged vertically, preferably one at the top of the guide rod 5 and the other near the cone seat 1 above the cone seat 1.

[0039] Preferably, the bottom of the cavity has a platform-shaped cavity structure with the cross-sectional area decreasing from top to bottom.

[0040] Preferably, the inner wall of the cylinder 4 is provided with a connecting edge 8 that is radially convex and has an annular structure at the top edge of the platform-shaped cavity structure. The side wall of the platform-shaped cavity structure is fixed to the bottom of the connecting edge 8 to improve the connection strength between the side wall of the platform-shaped cavity structure and the cylinder 4, thereby improving the stability of the emergency material lifting device structure and extending the service life of the emergency material lifting device.

[0041] Preferably, an upper cover 6 is provided to cover the feed inlet, and the upper cover 6 has a mounting hole in the middle for the guide rod 5 to pass through.

[0042] Preferably, the top cover 6 is fixedly provided with a handle and has an installation groove extending from the installation hole to the outer edge, so as to facilitate the fitting of the top cover 6 to the top of the cylinder 4 or the removal of the top cover 6 from the top of the cylinder 4.

[0043] Preferably, the bottom of the guide rod 5 is provided with a radially protruding limiting platform, and the cone seat 1 is sleeved onto the guide rod 5 from the bottom end of the guide rod 5, with its upper end face pressed against the bottom of the limiting platform;

[0044] It is also provided with a fastening nut 2 that is threadedly fastened to the bottom end of the guide rod 5, and the fastening nut 2 is pressed against the lower end face of the cone seat 1.

[0045] When using the above-mentioned emergency feeding device for kiln silos to add solid glass raw materials to the kiln head silo, the following process is included:

[0046] The first step is to place the cone seat 1 on a flat surface and fit it into the discharge port at the bottom of the cylinder 4 to block the discharge port; at this time, the cylinder 4 is firmly placed on the cone seat 1.

[0047] The second step is to add a sufficient amount of solid glass material into the cylinder 4 through the feed port at the top of the cylinder 4, and then put the upper cover 6 on the feed port at the top of the cylinder 4 so that the guide rod 5 can be inserted into the mounting hole through the mounting rail groove.

[0048] The third step involves hoisting the emergency lifting device to the top of the kiln head silo opening using the hook at the top of the guide rod 5. During this process, the cylinder 4 presses down on the cone seat 1 under its own weight and the weight of the glass solid raw material, keeping the cone seat 1 sealed and blocking the discharge port.

[0049] The fourth step is to hoist the cone seat 1 down so that the cylinder 4 is placed at the top of the kiln head hopper opening. Then the cone seat 1 continues to move downward until the cone seat 1 separates from the cylinder 4 and no longer blocks the discharge port. The glass solid raw material falls into the kiln head hopper from the discharge port, completing the feeding.
