Description

Technical Field

[0001] The utility model belongs to the field of unloading equipment, in particular to a ton bag breaking device. Background Art

[0002] In the field of hydrometallurgy, the extraction of valuable elements is mostly carried out by leaching kettle for reduction and replacement reaction. In the leaching process, the raw material bags are broken and fed. Since there are many problems with manual knives breaking bags, bag breaking mechanisms are currently used for bag breaking. The mainstream bag breaking mechanism mainly relies on the bag's own gravity to break the bag. Since the bag itself has a certain toughness, the bag breaking effect is poor.

[0003] A Chinese invention patent with patent number CN202110751882.5 discloses a bag breaking mechanism, including a feeding bin, a blade assembly and a heating assembly, wherein the feeding bin is a cavity with an opening on one side; the blade assembly includes a connecting bracket and a blade, the connecting bracket is connected to the feeding bin, the blade is connected to the connecting bracket, and faces the opening and forms an angle with the horizontal plane; the heating assembly contacts the blade and is electrically connected to an external power supply to heat the blade after power is turned on.

[0004] After verification, the above invention still has the following shortcomings: in the actual operation process, the temperature of the heating blade is difficult to control. If the temperature is too high, the blade or the cutting edge will stick to the melted plastic of the bag when scalding the ton bag, affecting the subsequent bag breaking work. If the temperature is set too low, it will not work, and there will be problems such as the bag cannot be broken or the break is small. Especially in hydrometallurgy, the ton bag and the material inside the bag contain water, which makes it difficult to control the blade temperature and unreliable to use, thereby reducing the bag breaking efficiency. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a ton bag breaking device with better bag breaking effect and more reliability.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A ton bag breaking device comprises a base, a plurality of support frames are arranged on the base, each support frame is installed with a tool by means of a pin shaft, the tool body is gathered upward in a cone shape, the blade part of the tool is located on the outside of the tool body, each tool is provided with a connecting rod inwardly, the movable end of the connecting rod is connected to a hydraulic lifting column, the connection is a slidable hinge structure, the bottom of the hydraulic lifting column is fixed on the base, and the hydraulic lifting column is connected to a hydraulic pump station through a hydraulic pipeline.

[0008] Preferably, the connecting rod is arranged at the lowermost end of the knife body.

[0009] Preferably, a connecting rod frame is provided at the top end of the hydraulic lifting column for connecting the movable end of the connecting rod.

[0010] Preferably, a vertically upward pointed rod is provided on the connecting rod frame, and the top end of the pointed rod is slightly higher than the top end of the tool.

[0011] Preferably, reinforcing ribs are provided between the support frames.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] By setting up a hydraulic structure, the utility model has the ability to actively break the bag instead of using traditional gravity to break the bag. The size of the break can be controlled manually, which solves the problems of poor reliability of existing bag breaking devices and frequent failure to break the bag or small break, thereby improving the bag breaking efficiency.

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 and Figure 2 As shown, a ton bag breaking device includes a base 1, a plurality of support frames 2 are arranged on the base 1, and a tool 3 is installed on the support frame 2 by means of a pin shaft. The tool 3 is gathered upward in a cone shape, and each tool 3 is provided with a connecting rod 4 inwardly. The movable end of the connecting rod 4 is connected to the hydraulic lifting column 5, and the connection is a slidable hinge structure. The bottom of the hydraulic lifting column 5 is fixed on the base 1, and the hydraulic lifting column 5 is connected to the hydraulic pump station 7 through a hydraulic pipeline 6.

[0019] The base 1 is composed of two mutually perpendicular stainless steel square tubes. The support frame 2 is preferably four and is respectively installed at the two ends of the two square tubes. The support frame 2 is installed with a tool 3 by a pin shaft. The blade part of the tool 3 is located on the outside of the blade body. The blade body of the tool 3 is fixed inwardly and perpendicularly to the blade body 3 with a connecting rod 4. The movable end of the connecting rod 4 is connected to the hydraulic lifting column 5. The connection is a slidable hinge structure. All the tools 3 gather upward in a cone shape, that is, all the tools 3 are in a convergent state. At this time, the hydraulic lifting column 5 should be in a retracted state.

[0020] In this embodiment, the connecting rod 4 is disposed at the lower part of the cutter 3 to ensure that the rotation stroke of the cutter 3 during operation meets the bag breaking requirement.

[0021] In this embodiment, a connecting rod frame 8 is provided at the top of the hydraulic lifting column 5 for connecting the movable end of the connecting rod 4 .

[0022] In this embodiment, a vertically upward pointed rod 9 is provided on the connecting rod frame 8, and the top of the pointed rod 9 is slightly higher than the top of the cutter 3. The pointed rod 9 can not only guide the cutter 3 to penetrate into the ton bag, but also reduce the wear of the top of the cutter 3.

[0023] In this embodiment, reinforcing ribs 10 are provided between the support frames 2 .

[0024] The working principle of the utility model is as follows:

[0025] First, fix the device above the leaching kettle or other equipment, and make the cutter 3 in a convergent state, lift the ton bag filled with materials above the device and make the top of the pointed rod 9 pierce the ton bag, then manually control the hydraulic pump station 7 to transport hydraulic oil to the hydraulic lifting column 5, so that the upper part of the hydraulic lifting column 5 is lifted, and at the same time drive the connecting rod 4 and the cutter 3 to move. The cutter 3 will cut the ton bag during the process of opening outwards. After the break is large enough, operate the hydraulic lifting column 5 to make it descend, and finally recycle all the cutters 3 to complete a bag breaking process.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
