Description

Technical Field

[0001] The utility model relates to the technical field of hoppers, in particular to a hopper for lifting with convenient feeding. Background Technique

[0002] Storage tanks are used to store refined chemical substances such as acids and alkalis, alcohols, gases, and liquids. Storage tanks have been widely used and can be manufactured into multiple varieties such as vertical, horizontal, transportation, and stirring. Generally, in vertical storage tanks, substances to be stored are filled through openings at the top. Moreover, the heights of vertical storage tanks vary. When filling large storage tanks with materials, generally pumping is used, but for very tall small storage tanks, hoisting is usually selected, especially when transferring a relatively small amount of materials, a hoisting hopper is generally used for transfer.

[0003] The opening at the top of the storage tank is generally more than ten meters high, and there are also ultra-high storage tanks dozens of meters high. Filling operations at high altitudes into such large storage tanks face many difficulties. Use a crane to lift the transfer bin and place it at the original position of the material to feed the hopper, then lift the hopper above the feeding port of the storage tank, and then put the material in the hopper into the storage tank. In this process, a construction worker is required to feed the hopper from below and close the valve at the bottom of the hopper. When the hopper is lifted to the opening at the top of the storage tank, another construction worker is needed to climb to the opening at the top of the storage tank more than ten meters high with the help of a lift truck, and then manually open the valve below the hopper at the top of the storage tank so that the raw materials can be smoothly injected into the storage tank. This method not only takes time and effort, but also easily causes the scattering and waste of raw materials during the valve operation process, increasing the construction cost and safety risks. There are also certain safety hazards for construction workers working at high altitudes.

[0004] Based on this, the utility model designs a hopper for lifting with convenient feeding to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hopper for lifting with convenient feeding, the pure mechanical structure of this device can adapt to a wide range of environments and has high reliability. It can remotely control the feeding into the hopper or transfer the material in the hopper to the storage tank through a crane. The whole process does not require manual opening of the valve by personnel, making the whole filling process smoother and more controllable. Moreover, there is no electrical equipment, and all are mechanical structures, so there is no need to consider the erosion and damage of the material to the valve body and electronic equipment. It is completely an external operation, and only the hoisting device needs to be controlled to complete. This not only improves the operation efficiency, but also reduces material waste while ensuring construction safety, meeting the safety, high-efficiency, and environmental protection concepts of construction management.

[0006] The utility model is realized as follows: A hopper for lifting with convenient feeding, comprising:

[0007] A hopper, a valve body cover, a positioning pipe, and a reinforcing strut;

[0008] The hopper has a funnel-shaped structure. The top of the hopper is the feeding opening, and the bottom of the hopper is the discharging opening. The diameter of the discharging opening is smaller than that of the feeding opening.

[0009] The reinforcing strut is a steel pipe. The reinforcing strut is horizontally arranged on the discharging opening, and a lifting lug is arranged at the outer end of the reinforcing strut.

[0010] The positioning pipe is a straight pipe with openings at both ends. The positioning pipe is vertically fixed at the intersection of multiple reinforcing struts, and the axis of the positioning pipe coincides with the vertical axes of the hopper and the discharging opening.

[0011] The valve body cover is a cone with a smaller top and a larger bottom. The valve body cover is located inside the hopper cavity, and the valve body cover can be opened and sealed to cover the top of the discharging opening.

[0012] A valve rod is vertically arranged at the top of the valve body cover. A lifting ring is arranged at the top of the valve rod. The valve rod is vertically slidably arranged in the positioning pipe, and the lifting ring is located above the positioning pipe.

[0013] Further, an annular limiting ring and the valve body cover are arranged at the bottom of the valve body cover. The limiting ring extends downward at the bottom of the valve body cover. The sealing ring is sleeved on the outer wall of the limiting ring. The valve body cover is hermetically covered on the discharging opening through the sealing ring.

[0014] Further, the positioning pipe and the valve rod are in clearance fit, and the clearance does not exceed 5 mm.

[0015] Rubber stoppers are arranged at both the upper and lower ends of the valve rod, and the stoppers are larger than the aperture of the positioning pipe.

[0016] Further, the hopper is a conical funnel. Both the feeding opening and the discharging opening are round holes. Two reinforcing struts symmetrically support the feeding opening, and each reinforcing strut coincides with a diameter of the feeding opening.

[0017] The beneficial effects of the present utility model are as follows: 1. The present utility model uses a funnel-shaped hopper to temporarily store and transfer materials. The conical hopper of the device with a larger top and a smaller bottom is more convenient for feeding and discharging. The feeding opening is large, and materials can be conveniently poured directly into the hopper. Moreover, the valve body cover blocks the discharging opening, and the materials can be stored in a sealed manner.

[0018] 2. The valve body cover inside the device will be self-pressed downward under the pressure of the materials. The more materials there are, the closer the pressing is, and the better the sealing performance is. It will not be more likely to leak because of more materials. Moreover, as long as the valve rod is not pulled upward, the device will naturally press downward on the discharging opening, so that the discharging opening is in a normally closed state, and the structural design of the device has good sealing performance.

[0019] 3. Since the valve body cover of this device can be lifted by the sling ring and the hook ring of the auxiliary boom of the crane, it can be operated in the crane, which is convenient for operation. This enables the discharge port of this device to discharge materials, and also allows this device to be immersed in the water tank for feeding, making it convenient and flexible to use.

[0028] Please refer to Figures 1 to 5 As shown, the present utility model provides a hopper for a crane with convenient feeding. In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0029] In a specific embodiment of the technical solution of the present utility model:

[0030] It includes a hopper 1, a valve body cover 2, a positioning pipe 3, and a reinforcing strut 4;

[0031] The hopper 1 is a conical funnel. The top of the hopper 1 is the feeding port 11, and the bottom of the hopper 1 is the discharging port 12. The diameter of the discharging port 12 is smaller than that of the feeding port 11; both the feeding port 11 and the discharging port 12 are round holes.

[0032] The reinforcing strut 4 is a steel pipe. Two reinforcing struts 4 are horizontally arranged on the discharging port 12. The two reinforcing struts 4 symmetrically support the feeding port 11, and each reinforcing strut 4 coincides with a diameter of the feeding port 11.

[0033] A lifting lug 41 is provided at the outer end of the reinforcing strut 4; through the lifting lug 41, the entire hopper can be lifted smoothly and the force is evenly distributed. The supporting force is also strengthened by the reinforcing strut 2, effectively avoiding the deformation of the feeding port 11 due to stress concentration.

[0034] The positioning tube 3 is a straight tube with openings at both ends. The positioning tube 3 is vertically fixed at the intersection of multiple reinforcing struts 4. The axis of the positioning tube 3 coincides with the vertical axes of the hopper 1 and the discharging port 12, that is, the positioning tube 3 is vertically arranged at the intersection of multiple reinforcing struts 4, forming a guiding and limiting effect on the valve rod 21; the positioning tube 3 and the valve rod 21 are in clearance fit, and the clearance does not exceed 5 mm.

[0035] Blocks are provided at both the upper and lower ends of the valve rod 21, and the blocks are larger than the inner diameter of the positioning tube 3. The up and down strokes of the valve rod 21 are limited by the blocks to prevent the valve rod 21 from disengaging from the positioning tube 3, and it can also prevent the lifting ring 22 and the valve body cover 2 from colliding and damaging the positioning tube 3. Therefore, the blocks can also be made of rubber material, which can not only limit the position but also play a buffering role. The horizontal outer diameters of the lifting ring 22 and the valve body cover 2 are also larger than the inner diameter of the positioning tube 3; ensuring stable cooperation between the lifting ring 22 and the valve body cover 2 and the blocks.

[0036] The valve body cover 2 is a cone with a smaller top and a larger bottom. The valve rod 21 is vertically arranged at the top of the valve body cover 2, and a lifting ring 22 is provided at the top of the valve rod 21. The valve rod 21 is vertically slidably arranged in the positioning tube 3, and the lifting ring 22 is located above the positioning tube 3.

[0037] The valve body cover 2 is located inside the hopper 1. The valve body cover 2 seals and covers the top of the discharging port 12 and can also be lifted to open the discharging port 12; an elastic rubber sealing ring 23 is provided at the bottom of the valve body cover 2, and an annular limiting ring 24 also extends downward from the bottom of the valve body cover 2. The sealing ring 23 is sleeved on the outer wall of the limiting ring 24, and the valve body cover 2 seals and covers the discharging port 12 through the sealing ring 23. Through this elastic sealing ring 23, it can be pressed tightly against the discharging port 12, effectively achieving a tight sealing effect. Moreover, the sealing ring 23 preferably has a certain height to facilitate buffering during the downward pressing of the valve rod 21 and avoid damage to the valve body cover 2 due to heavy pressure. By observing that the limiting ring 24 extends downward and fits with the inner wall of the discharging port 12, and the closing state of the limiting ring 24 and the discharging port 12 is used to judge whether the valve body cover 2 is normally closed, which is simple, practical and convenient to operate.

[0038] It should be noted that:

[0039] 1. When hoisting liquid materials at high altitude, generally a lifting bucket similar to an excavator is used. The two halves of the excavator bucket are closed to grab the liquid. However, this method of grabbing materials is generally suitable for large-volume solids, such as stones. Even relatively fine sand and soil are not easy to grab. When using this kind of hoisting device to transfer liquid materials, a large amount of leakage will occur, not only causing waste of materials, but also polluting the environment. This device will not have such problems. It has a self-closing function. Under the action of the gravity of the material pressing down, it will automatically press down to close the valve body cover 2, achieving the effect of self-sealing.

[0040] 2. There are also funnel-shaped material transfer buckets now. A valve body is required at the bottom. If it is an electromagnetic valve, it is very easy to be difficult to seal due to the liquid properties of the material or the slurry of the material. And it is very difficult for electronic equipment to bear the weight of several tons, which requires very large hydraulic equipment and power control equipment. The actual production difficulty is great and the reliability is not high. Moreover, this kind of device cannot be immersed at all. This device is a pure mechanical structure, and the structure is particularly simple, and the operation is also simple. That is, it does not require personnel to work at high altitude, nor electronic equipment, and even less hydraulic equipment. The whole device can be immersed in the liquid. Even if there is mud and particulate matter, this device can also press the valve body cover 2 against the feeding port 12 by pressing down the valve stem 21. The sealing effect is good, the operation is simple, and the safety is high.

[0041] There are two feeding methods for the utility model. One is to inject materials into the hopper 1 from the feeding port 11, which is generally used for transferring materials from the storage container of a vehicle to a high-altitude storage tank. Place the hopper 1 below the discharge port of the vehicle. When the valve of the vehicle is opened, the liquid material directly falls into the hopper 1 from the feeding port 11. The material presses down on the valve body cover 2. There is no need for other devices to press. The valve body cover 2 of this device will automatically press down under the impact and pressure. The more materials there are, the tighter the pressing is, and the better the sealing performance of the valve body cover 2 is.

[0042] When pouring materials into a pool with an open top, the entire hopper 1 of this device can be placed into the liquid material in the pool. When the feeding port 12 enters the pool, the valve body cover 2 will receive an upward thrust under the pressure of the material below. As long as the valve stem 21 is not pressed down, the liquid material will automatically rush into the hopper 1 from the direction of the feeding port 12. The operation is simple, and the entire hopper 1 can also be directly immersed in the pool. Both the feeding port 11 and the feeding port 12 can feed materials. The feeding method is diverse and the use environment is wider.

[0043] When discharging, it is the same. Hang the hopper 1 on the lifting lug 41 through a crane, lift the hopper 1, and hoist the discharging opening 12 at the high-altitude top opening of the storage tank. Then, pull the lifting ring 22 upward through the auxiliary boom hook of the crane, and the valve body cover 2 rises along the positioning pipe 3. Since the valve body cover 2 is a conical structure with a smaller upper part and a larger lower part, as long as the sealing ring 23 is pulled to generate a gap, the liquid material will flow downward rapidly, and the impact force will push the valve body cover 2 upward. As long as the bottom of the valve body cover 2 is also immersed in the liquid material, an upward buoyancy force will be generated, which can offset a part of the downward pressing force of the material, making it more labor-saving and smooth to open the discharging opening 12.

[0044] Although the specific embodiments of the present invention have been described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be covered by the scope protected by the claims of the present invention.
