Description

Technical Field

[0001] This utility model relates to the field of graphite loading technology, and in particular to a movable lifting hopper for isostatic graphite loading. Background Technology

[0002] The isostatic pressing graphite green billet is loaded by pressing powder from the silo and conveying it directly into the mobile loading hopper through a chute. The hopper has a valve and a discharge pipe at the bottom. A crane is used to lift the hopper to the mold, open the bottom valve, and manually control the discharge speed and measure the height after loading to meet the process requirements.

[0003] However, the traditional hopper design without rollers prevents it from moving horizontally on the ground, requiring overhead cranes to lift it during loading. This single method of movement makes adjusting the hopper's position within the workshop extremely inconvenient, increasing the frequency and difficulty of crane use, extending loading preparation time, and reducing overall production efficiency.

[0004] During the feeding process, the small gap between the lower part of the traditional frame and the feeding valve severely affects the operator's normal operation. The confined operating space makes operations such as connecting air pipes and opening and closing valves difficult, which not only increases the risk of operational errors but may also cause interruptions in the feeding process due to operational inconvenience, affecting the continuity of production. Utility Model Content

[0005] The purpose of this invention is to provide a movable lifting hopper for isostatic graphite loading, which solves the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a movable lifting hopper for isostatic graphite loading, including a hopper, a feed inlet and a three-stage sealing valve. The feed inlet is provided at the top of the hopper, and a negative pressure dust removal interface is provided at the front end of the feed inlet. Lifting lugs are provided on both sides of the top of the hopper, high-frequency pneumatic vibrators are provided on both sides of the bottom of the hopper, a three-stage sealing valve is provided at the bottom of the hopper, a frame is provided at the four corners of the hopper, and rollers are provided on both sides of the front and rear ends of the hopper. A sliding groove is opened on the end face of the frame facing the hopper, and the rollers are placed in the sliding groove.

[0007] Preferably, the tops of the four frames are connected by crossbars, and the two adjacent frames at the front and rear ends of the hopper are connected by crossbars.

[0008] Preferably, the bottom of the frame is equipped with a first roller, and the top of the frame is fixed with a second lifting lug.

[0009] Preferably, a limiting block is fixed between two adjacent frames on both sides of the hopper, and the limiting block is located in the lower middle part of the frame.

[0010] Preferably, the size of the second roller matches the size of the groove, and the second roller is placed in the groove.

[0011] Preferably, four rollers are provided at the front and rear ends of the hopper, and pin holes are provided below the rollers. The pin holes are opened on the side wall of the hopper. Insertion holes are provided at the center and lower part of the frame, and fixing pins are provided in the insertion holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a movable lifting hopper for isostatic graphite loading. The hopper moves up and down within a groove on the frame via rollers (two in total), and its relative position to the frame can be adjusted using lifting lugs (one and two). During unloading, after removing the fixing pin, the hopper can be lowered to the bottom, while the frame can rise via lifting lugs (two in total), effectively increasing the distance between the lower part of the frame and the three-stage sealing valve. This adjustment provides ample space for operators to connect air pipes and operate valves during unloading, avoiding operational obstruction caused by insufficient space, and improving the convenience and safety of unloading operations.

[0014] 2. This utility model provides a movable lifting hopper for isostatic graphite loading. The frame is equipped with rollers, and the hopper can be lifted using lifting lugs, achieving horizontal movement in conjunction with the frame's mobility. This design changes the single movement method relying solely on overhead crane lifting. During loading, the rollers can be used to push the frame, coordinating with lifting to achieve flexible movement and horizontal shifting of the hopper. Frequent reliance on overhead cranes for precise positioning is eliminated, significantly improving operational convenience. Operators can more easily move the hopper to the loading port, reducing cumbersome lifting steps, saving loading preparation time, and improving overall operational efficiency.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] Combination Figures 1 to 5 As shown, this utility model discloses a movable lifting hopper for isostatic graphite loading, comprising a hopper 1, a feed inlet 2, and a three-stage sealing valve 6. The feed inlet 2 is provided at the top of the hopper 1, and a negative pressure dust removal interface 3 is provided at the front end of the feed inlet 2. Lifting lugs 4 are provided on both sides of the top of the hopper 1, and high-frequency pneumatic vibrators 5 are provided on both sides of the bottom of the hopper 1. The three-stage sealing valve 6 is provided at the bottom of the hopper 1. A frame 7 is provided at the four corners of the hopper 1. Rollers 81 are provided on both sides of the front and rear ends of the hopper 1. A sliding groove 85 is provided on the end face of the frame 7 facing the hopper 1, and the rollers 81 are placed in the sliding groove 85.

[0024] The tops of the four frames 7 are connected by crossbars, and the two adjacent frames 7 at the front and rear ends of the hopper 1 are connected by crossbars.

[0025] The bottom of the frame 7 is equipped with a first roller 71, and the top of the frame 7 is fixed with a second lifting lug 72.

[0026] Limiting blocks 83 are fixed between two adjacent frames 7 on both sides of the hopper 1. The limiting blocks 83 are located in the lower middle part of the frame 7.

[0027] The dimensions of roller 81 match the dimensions of the slide groove 85, and roller 81 is placed in the slide groove 85.

[0028] Four rollers 81 are provided at the front and rear ends of the hopper 1. A pin hole 84 is provided below the roller 81. The pin hole 84 is opened on the side wall of the hopper 1. An insertion hole 82 is provided at the center and lower part of the frame 7. A fixing pin 8 is provided in the insertion hole 82.

[0029] Specifically, four frames 7 form a frame, and the hopper 1 is loaded into the frame formed by the frames 7. The hopper 1 is placed in the slide groove 85 through the rollers 81, so that the hopper 1 can move up and down in the frame formed by the frames 7.

[0030] The high-frequency pneumatic vibrator 5 has a frequency of 50Hz and an amplitude of ≤2mm;

[0031] The three-stage sealing valve 6 consists of a three-layer structure: the upper layer is a pneumatic butterfly valve for rapid opening and closing; the middle layer is a flexible silicone skirt for dynamic sealing; and the lower layer is a magnetic flange for automatic locking when docking with the mold.

[0032] Negative pressure dust removal interface 3: Dust removal hose connected to the side of the valve.

[0033] Working principle:

[0034] The frame consisting of hopper 1 and frame 7 can be lifted using lifting lug 1 4 and lifting lug 2 72, and the frame can be pushed using roller 1 71;

[0035] Use the lifting lug 4 to lift the hopper 1 and move it to the top of the frame. At this time, the pin holes 84 at the lower front and rear ends of the hopper 1 are aligned with the insertion holes 82 in the middle of the frame 7. Insert the fixing pin 8 into the pin hole 84 through the insertion hole 82 and fix the hopper 1 with the fixing pin 8, so that the hopper 1 is located at the top of the frame.

[0036] Pull the fixing pin 8 out of the insertion hole 82 and the pin hole 84. Use the gravity of the hopper 1 and the roller 81 to slide down in the slide groove 85 to make the hopper 1 move down. When the two sides of the bottom of the hopper 1 are in close contact with the limiting side block 83, the hopper 1 is located at the lowest position of the hopper 1.

[0037] Furthermore,

[0038] First, loading:

[0039] Using the lifting lug 4 on hopper 1, hopper 1 is hoisted to the loading position. Then, utilizing the equipment's translation function and the movement characteristics of frame 7, hopper 1 is moved horizontally to the loading port. At this point, through alignment, the feed inlet 2 of hopper 1 is aligned with the discharge port of the hopper. Subsequently, the pneumatic telescopic flange of the hopper discharge port descends, forming a sealed connection with the feed inlet 2 of hopper 1. This sealing design effectively prevents material leakage and dust spillage during the loading process.

[0040] The dust removal hose connected to the negative pressure dust removal interface 3 of hopper 1, and the air pipe of the feed pneumatic butterfly valve, provide a guarantee for dust removal and valve control during the loading process. After opening the feed pneumatic butterfly valve of hopper 1 and the hopper pneumatic butterfly valve, the material flows from the hopper into hopper 1 through the discharge port under its own gravity until loading is completed. After loading is completed, the above two pneumatic butterfly valves are closed to cut off the material flow path;

[0041] Afterwards, the dust removal hose and the pneumatic butterfly valve air pipe are disconnected, the pneumatic telescopic flange at the hopper discharge port rises, and then hopper 1 is moved horizontally out of the loading position to complete the loading. Throughout the process, the opening and closing control of each valve, the function of the sealing structure, and the operation of the dust removal system jointly ensure the standardization and environmental protection of the loading process.

[0042] Secondly, unloading:

[0043] After the hopper 1, which is filled with material, is lifted by the lifting lug 4 or moved horizontally by the roller 71 of the frame 7 to the unloading position, the air pipe is connected to the high-frequency pneumatic vibrator 5 and the upper pneumatic butterfly valve of the three-stage sealing valve 6 to provide power and valve control support for unloading.

[0044] Lifting lug 4 of hopper 1 is used to remove the fixing pin 8 in the middle of frame 7. At this time, under its own weight, hopper 1 slides down in the slide groove 85 of frame 7 with the help of roller 81, thus lowering hopper 1. Then, lifting lug 72 of frame 7 is used to raise frame 7 until the hopper rollers descend to the positioning pin at the bottom of frame 7. If it continues to rise, the entire frame 7 and hopper 1 will be raised together.

[0045] After the equipment is hoisted to the unloading position, the three-stage sealing valve 6 begins to function: the lower magnetic flange automatically locks when docking with the mold, the middle flexible silicone skirt ensures dynamic sealing and prevents material leakage during unloading; the upper pneumatic butterfly valve is opened, and the high-frequency pneumatic vibrator 5 is started at the same time. Under the high-frequency vibration of the vibrator, the material is quickly and smoothly discharged from the hopper 1 to the mold under the dual action of gravity and vibration until unloading is completed;

[0046] After unloading, close the pneumatic butterfly valve for hopper 1 and the high-frequency pneumatic vibrator 5. Then, lift hopper 1 away from the unloading position, lower the gantry crane until the bottom rollers of frame 7 touch the ground, and then lift hopper 1 up to a position where it can be inserted into the positioning pin in the middle of frame 7. That is, the insertion hole 82 in the middle of frame 7 is aligned with the pin holes 84 at the lower front and rear ends of hopper 1, and the fixing pin 8 can be inserted to complete the unloading process. When the two sides of the bottom of hopper 1 are in close contact with the limiting side blocks 83, hopper 1 is in the lowest position.
