Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] See also Figure 1-6The utility model provides the following technical solutions: an auxiliary adding structure for PVC additive production, comprising a second tank body 6, a limiting frame 4 is connected to the outer wall of the second tank body 6, an upper end of the limiting frame 4 is connected to the first tank body 5, a receiving component 8 is arranged on the outer wall of the first tank body 5, a mounting frame 2 is connected above the limiting frame 4 and located at the periphery of the first tank body 5, an extrusion discharging mechanism 1 is arranged between the mounting frame 2, the first tank body 5 and the second tank body 6, a liquid storage tank 3 is connected to the other end above the limiting frame 4, a quantitative injection component 9 is arranged above the liquid storage tank 3, and a pressurization stirring mechanism 7 is arranged inside the liquid storage tank 3.

[0025] Specifically, the receiving assembly 8 includes an external fixed cylinder 81, a rotating connection member 82, a bottom plate 83 and a discharge pipe 85. The external fixed cylinder 81 is connected to the outer wall of the first tank body 5, and the discharge pipe 85 is connected below the external fixed cylinder 81. The bottom plate 83 is provided at one end of the discharge pipe 85 away from the external fixed cylinder 81. The rotating connection member 82 is provided between the external fixed cylinder 81 and the bottom plate 83.

[0026] By adopting the above technical solution, under the action of the rotating connecting piece 82, the bottom plate 83 is moved to fit the bottom of the discharge pipe 85, and then the extrusion discharge mechanism 1 is used to extrude the additive production raw materials inside the second tank body 6. When the additive production raw materials overflow, the external fixed cylinder 81 can receive the overflowed additive production raw materials. When the additive production raw materials inside the external fixed cylinder 81 need to be taken out, under the action of the rotating connecting piece 82, the bottom plate 83 is moved away from the discharge pipe 85, and the additive production raw materials inside the external fixed cylinder 81 are discharged through the discharge pipe 85, which is convenient for the operator to take the material.

[0027] Specifically, the rotating connecting member 82 includes a fixed screw 821, a rotating rod 822, a rotating nut 823 and a through hole 824. The fixed screw 821 is connected to the side wall of the external fixed cylinder 81 and located on one side of the discharge pipe 85. The rotating rod 822 is connected to the side of the bottom plate 83 close to the fixed screw 821. A through hole 824 is provided on the rotating rod 822 at a position corresponding to the fixed screw 821. The rotating nut 823 is connected to the outer wall of the fixed screw 821 and located below the rotating rod 822.

[0028] By adopting the above technical solution, first, under the action of the through hole 824, the rotating rod 822 is rotated around the fixed screw 821, and the rotation of the rotating rod 822 drives the bottom plate 83 to rotate. When the bottom plate 83 rotates to the bottom of the discharge pipe 85, the bottom plate 83 is moved up again. When the bottom plate 83 is in contact with the bottom of the discharge pipe 85, the rotating nut 823 is rotated to rotate and move upward along the fixed screw 821. When the rotating nut 823 is in contact with the side wall of the rotating rod 822, the rotation of the rotating nut 823 is stopped. Under the action of the rotating nut 823, the rotating rod 822 can be tightly fixed, and then the bottom plate 83 can be tightly fixed.

Under the action of the sealing ring 84 and the sealing groove, the bottom plate 83 and the discharge pipe 85 can be sealed to prevent the additive production raw materials inside the discharge pipe 85 from dripping into the surrounding environment through the gap.

[0031] When the present embodiment is used, the rotating rod 822 is first rotated around the fixed screw 821 under the action of the through hole 824, and the rotating rod 822 rotates to drive the bottom plate 83 to rotate. When the bottom plate 83 rotates to the bottom of the discharge pipe 85, the bottom plate 83 is moved upward. When the bottom plate 83 fits the bottom of the discharge pipe 85, the rotating nut 823 is rotated to rotate and move upward along the fixed screw 821. When the rotating nut 823 fits the side wall of the rotating rod 822, the rotating nut 823 is stopped. During the production process of PVC additives, the raw materials required for the production of PVC additives are injected into the liquid storage tank 3, and then the pressurized stirring mechanism 7 is used to input the raw materials required for the production of PVC additives in the liquid storage tank 3 into the first tank body 5, and then the extrusion discharge mechanism 1 is used to discharge the first tank body 5. The raw materials required for the production of PVC additives in the first tank body 5 are squeezed and injected into the second tank body 6 to assist in the addition operation of the raw materials for the production of PVC additives. The extrusion discharging mechanism 1 is used to extrude the raw materials for the production of additives in the second tank body 6. When the raw materials for the production of additives overflow, the external fixed cylinder 81 can receive the overflowed raw materials for the production of PVC additives. When it is necessary to take out the raw materials for the production of additives in the external fixed cylinder 81, the rotating nut 823 is rotated to rotate and move downward along the fixed screw 821. Under the extrusion action of gravity and the discharge pipe 85 and the raw materials for the production of PVC additives in the external fixed cylinder 81, the raw materials for the production of PVC additives in the external fixed cylinder 81 are moved away from the discharge pipe 85. The raw materials for the production of PVC additives in the external fixed cylinder 81 are discharged through the discharge pipe 85, which is convenient for the material taking operation.

[0036] When this embodiment is used, the sealing plug 91 is first taken out from the inside of the measuring cylinder 93, and the sealing plug 91 moves to drive the rubber ring 94 away from the clamping groove, and then the PVC additive production raw material is injected into the measuring cylinder 93. During the injection process, the injection amount of the PVC additive production raw material can be judged by the scale line on the measuring cylinder 93. When the PVC additive production raw material reaches the required amount, the valve on the connecting pipe 92 is turned, and the PVC additive production raw material in the measuring cylinder 93 is injected into the liquid storage tank 3 through the connecting pipe 92, which is convenient for the operator to quantitatively inject the PVC additive production raw material and ensure the quality of the produced PVC additive.

A boosting pump is connected to the side wall of the liquid storage tank 3, and a connecting pipe is connected between the boosting pump and the liquid storage tank 3 and the first tank body 5.

When the rotating nut 823 fits the side wall of the rotating rod 822, the rotating nut 823 is stopped. During the production process of PVC additives, the sealing plug 91 is first taken out from the inside of the measuring cylinder 93. The movement of the sealing plug 91 drives the rubber ring 94 away from the clamping groove, and then the PVC additive production raw materials are injected into the inside of the measuring cylinder 93. During the injection process, the injection amount of the PVC additive production raw materials can be judged by the scale lines on the measuring cylinder 93. When the PVC additive production raw materials reach the required amount, the valve on the connecting pipe 92 is rotated, and the PVC additive production raw materials in the measuring cylinder 93 are injected into the liquid storage tank 3 through the connecting pipe 92. , which is convenient for operators to quantitatively inject PVC additive production raw materials to ensure the quality of the produced PVC additives, and then use the booster stirring mechanism 7 to input the raw materials required for PVC additive production in the liquid storage tank 3 into the first tank body 5, and then use the extrusion discharging mechanism 1 to extrude the raw materials required for PVC additive production in the first tank body 5 into the second tank body 6, to assist in completing the addition operation of PVC additive production raw materials, and use the extrusion discharging mechanism 1 to extrude the additive production raw materials in the second tank body 6.
