[0022] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0023] like Figure 1 As shown, a special tool for storing master batches includes a box body 3, a cover plate 4 arranged on the box body 3, a bracket 1 for installing the box body 3, and casters 11 arranged at the bottom of the bracket 1, a filter is arranged in the box body 3, the bottom of the box body 3 is a funnel structure, a conveying channel 8 is arranged at the bottom of the box body 3, the top of the bracket 1 is higher than the top of the box body 3, and the bag containing the master batch is limited by the bracket 1 during the unloading process.

[0024] In actual use, the bag containing the masterbatch is hoisted into the air by an electric hoist, the bracket 1 and the box 3 are moved to the bottom of the bag by casters 11, the cover 4 is opened, and the bag on the electric hoist is slowly lowered to the bracket 1 on the top of the box 3. Through the gap between the bracket 1 and the box body 3, use scissors to cut the rope tied at the bottom of the material bag, so that the masterbatch enters the box body 3 for masterbatch storage through the cut channel, and the steel wire pipe of the suction machine is fixedly connected to the conveying channel 8 through a clamp, and finally the step of the masterbatch entering the silo through the box body 3 is completed; the bracket 1 is used as a safety insurance, which is convenient for the operator to operate and can also ensure the safety of the operator. The whole operation process can effectively reduce the risk and avoid the sudden and violent impact of the masterbatch when opening the bottom of the material bag to injure the arm. The bracket 1 through the raised part can also effectively bear the weight of the material bag, so that the masterbatch can slowly flow out after the bottom is opened, and the bottom of the box body 3 adopts a funnel structure, which can prevent the masterbatch from remaining in the box body 3. The filter can allow the masterbatch to pass smoothly while isolating various sundries that are slightly larger than the masterbatch.

[0025] As a further improvement, two slide grooves 5 are provided on the top of the box body 3 , and the two sides of the cover plate 4 are slidably arranged between the two slide grooves 5 , and the cover plate 4 is opened and closed by pulling out the slide grooves 5 .

[0026] Since the top of the box body 3 is relatively high, it is not convenient to operate with a flip cover, and the size of the opening is also difficult to control. Therefore, two slide grooves 5 are used to connect the two sides of the feed port on the top of the box body 3, so that the cover plate 4 can be opened and closed in a pull-out manner. When the cover plate 4 needs to be opened and closed or removed, it is more convenient and simple, and the operator can stand on the ground to perform direct operation.

[0027] Further improvement is that the box 3 (3) box 3 is made of 2mm thick 304 stainless steel plate, and the volume of the box 3 is 1.2m 3 The bracket 1 is constructed of 5mm*5mm angle steel; the top of the bracket 1 is constructed into a mesh-shaped frame structure by 5mm*5mm angle steel.

[0028] The box 3 is made of 2mm 304 stainless steel plate and has a volume of 1.2 cubic meters. It can accommodate one ton of masterbatch and is rust-proof and wear-resistant. It can store masterbatch for a long time, and the box 3 itself is strong and rust-proof and durable. Since the masterbatch has a large downward impact force when feeding, it may not only knock the tools in the hand away, but also injure the arms. Therefore, the frame material of the bracket 1 is 5mm*5mm angle steel, which is firm and thick and has a strong load-bearing capacity. In particular, the top of the bracket 1 is built into a mesh-shaped frame structure through 5mm*5mm angle steel, which can form a certain protection for the front and rear sides of the bag containing the masterbatch during the left and right limit process.

[0029] As a further improvement, a handle 6 is provided on one side of the bracket 1 .

[0030] The handle 6 can facilitate the movement of the entire tool.

[0031] A further improvement is that the filter screen adopts a stainless steel filter screen with 4 meshes and a wire diameter of 1.6 mm.

[0032] The filter screen uses a 4-mesh wire diameter of 1.6mm, which can just filter through the pore size of the masterbatch and prevent debris from entering the screw injection device.

[0033] A further improvement is that a three-way pipe 2 is provided at the bottom of the conveying channel 8 and the box body 3, the conveying channel 8 is connected to the bottom interface of the three-way pipe 2, a control valve 10 is provided on the side interface of the three-way pipe 2, and the air pressure difference in the conveying channel 8 is controlled by the control valve 10; the three-way pipe 2 adopts a reducing tee, the control valve 10 is a ball valve, and the air inlet of the control valve 10 is provided with a stainless steel elbow 7 with a 180-degree bending arc; the conveying channel 8 is also provided with a plurality of vents 9.

[0034] The bottom conveying channel 8 of the special tool can change the amount of air entering the conveying channel 8 when an air pressure difference occurs by controlling the bypass control valve 10, and push the masterbatch into the silo with the most suitable air entry ratio. Among them, the conveying channel 8 is a DN45 stainless steel pipe, the three-way pipe 2 is a 50*50*25 reducing three-way pipe 2, the control valve 10 is a DN25 stainless steel ball valve, the stainless steel elbow 7 with a 180-degree bending arc is a DN25 stainless steel pipe, and several vents 9 are opened on the upper part of the DN45 stainless steel pipe. The bypass 180-degree DN25 stainless steel elbow 7 and the vents 9 on the DN45 stainless steel pipe form an internal and external air pressure difference, so that the air pushes the masterbatch forward and is introduced into the silo. The conveying channel 8 uses the bypass DN25 stainless steel pipe and ball valve to control the air entry amount of the internal and external pressure difference to achieve the most suitable ratio and the fastest conveying efficiency. This structure is simple and practical, with low matching cost, and the air pressure difference is used to make the masterbatch easily transported into the silo.

[0035] As a further improvement, the casters 11 include two 4-inch fixed casters 11 and two 4-inch universal casters 11 with brakes.

[0036] It can not only bear the weight of special tools and one ton of masterbatch, but also use the start-stop and move masterbatch storage box with two universal wheel brakes. The movement and stillness can be switched conveniently and quickly during operation.

[0037] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
