[0024] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme in the utility model will be described clearly and completely below in combination with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] As described above, the current tank body produces larger mechanical wear when shaking, which easily affects the service life of the tank body. The tank body only serves as a container for mixing materials, and the function is single. When discharging the completely mixed raw materials, the materials are discharged through a single discharge pipe, and the flushing of the discharge pipe when it is opened and closed easily affects the accuracy of the materials. The shaking method easily increases the generation of bubbles in the raw material mixing process.

[0026] In view of this, the utility model provides a rubber sealing element raw material mixing tank, which can discharge the completely mixed raw materials in stages through multiple discharge branch pipes 301 with different pipe diameters, continuously reduces the influence of the flushing caused by the opening and closing of the pipeline on the discharging accuracy, and improves the accuracy of the materials. Moreover, the mixing tank 1 is inclined, the shaft of the stirring part 2 coincides with the axis of the mixing tank 1, the stirring part 2 stirs while the mixing tank 1 is inclined to increase the mixing of the materials in the direction other than the stirring direction, which is different from shaking, and causes smaller mechanical wear to the mixing tank 1. The mixing tank 1 generates fewer bubbles when mixing, and the air pressure adjusting pipe 8 connected to the mixing tank 1 can perform negative pressure or pressure increasing treatment on the inside of the mixing tank 1 through external equipment, which plays a good auxiliary role in defoaming and pressure increasing discharge of the materials.

[0027] The mixing tank 1 is always sealed, the feeding is carried out through the multi-way feeding pipe 7, the internal air pressure regulation is also connected with the corresponding equipment outside through the air pressure regulating pipe 8 to regulate the pressure in the tank, the raw materials in the tank are discharged through the opening and closing of the discharge collecting pipe 4 and the discharge branch pipe 301, the tank body is not disassembled and opened, and the integrity of the tank body is ensured.

[0028] The utility model discloses a kind of raw material mixing tanks, especially a kind of rubber sealing element raw material mixing tank, including mixing tank 1, stirring part 2, discharge assembly 3, rack 5 and support baffle 6. Figures 1-5 Specifically describe the utility model. Embodiment

[0029] As shown in Figures 1-5 The utility model provides a kind of raw material mixing tank, especially a kind of rubber sealing element raw material mixing tank, including mixing tank 1, stirring part 2, discharge assembly 3, rack 5 and support baffle 6.

[0030] Wherein, mixing tank 1 is inclined to set, the inside of mixing tank 1 can be sealed and set, and a layer of anti-sticking layer is coated on the inner wall of mixing tank 1, which can reduce the rubber sealing element raw material on the inner wall of mixing tank 1 during mixing and discharging, and affect mixing and discharging. Stirring part 2 is arranged in the inside of mixing tank 1, stirring part 2 includes a plurality of stirring vanes 201, stirring vanes 201 are all connected to the same shaft, the shaft of stirring vane 201 and the top end in the inside of mixing tank 1 are rotatably connected together, and the motor fixedly connected to the top end outside mixing tank 1 drives the shaft. The shaft of stirring part 2 and the axial direction of mixing tank 1 coincide, since mixing tank 1 is inclined to set, the rubber sealing element raw material in the inside of mixing tank 1 is stirred by the rotation of stirring vane 201 in the tank, and due to the influence of gravity, the rubber sealing element raw material stirred in the tank will flow in the direction in which mixing tank 1 is inclined, increase the direction of rubber sealing element raw material mixing flow in the inside of mixing tank 1, and increase the uniformity and mixing uniformity of raw material mixing efficiency. If the rotation centrifugal force of rubber sealing element raw material in the inside of mixing tank 1 is too large due to the too fast rotation speed of stirring vane 201, the raw material rotating to a higher position in the inside of mixing tank 1 can also flow to a lower position by starting and stopping stirring part 2.

[0031] A discharge collecting pipe 4 is fixedly connected to the bottom of the inclined side outside mixing tank 1, and the rubber sealing element material mixed in the inside of mixing tank 1 can be discharged outward by gravity after the valve of discharge collecting pipe 4 is opened. A rack 5 is arranged at the bottom of mixing tank 1, the upper surface of rack 5 is the same as the inclined direction of mixing tank 1, and rack 5 is used for fixing mixing tank 1. Since mixing tank 1 is inclined to set, it is easy to vibrate when stirring part 2 is started, in order to further fix mixing tank 1, a support baffle 6 is fixedly connected to the end of the upper surface of rack 5 away from discharge collecting pipe 4, the top end of support baffle 6 and the edge of mixing tank 1 are fixedly connected together, and support baffle 6 can also maintain the support angle of mixing tank 1.

[0032] An L-shaped air pressure adjusting pipe 8 is fixedly connected to the outside of the mixing tank 1 near one side of the supporting baffle 6, the inside of the air pressure adjusting pipe 8 and the inside of the mixing tank 1 are connected together, and as shown in the figure, the air pressure adjusting pipe 8 passes through the supporting baffle 6 and extends to the side of the supporting baffle 6 away from the mixing tank 1. The other end of the air pressure adjusting pipe 8 is connected to a vacuum pump or an air compressor for negative pressure bubble removal or pressure boosting auxiliary discharge of the mixing tank 1 in a sealed state. The bottom edge in the mixing tank 1 is rounded to increase the flow of raw materials and reduce the dead angle of the container. Figure 2

[0033] In order to facilitate the feeding of the mixing tank 1 in a sealed state, a multi-way feeding pipe 7 is fixedly connected to the top of the outside of the mixing tank 1. Several branch pipes of the multi-way feeding pipe 7 serve as feeding pipes of different kinds of raw materials, and the main pipe of the multi-way feeding pipe 7 is connected to the mixing tank 1 to feed the inside of the mixing tank 1. An electric control cabinet 9 is fixedly connected to the side of the rack 5, and the PLC system of the electric control cabinet 9 controls the start and stop of the motor of the stirring part 2 and the rotating speed. Embodiment

[0034] Based on the first embodiment, in order to improve the accuracy of the discharge of the mixing tank 1 after mixing is completed, a set of discharge assemblies 3 is arranged outside the mixing tank 1, the discharge assemblies 3 include a plurality of discharge branch pipes 301, and the inside diameters of the discharge branch pipes 301 are different. Since the opening and closing of the pipe is a gradual shrinking process until the closing is completed, the closing is not completed instantaneously, so there is a phenomenon of material flushing when the discharge pipe is closed, which is easy to cause the discharge to exceed the material. Therefore, the early closing method is adopted to compensate for the lack of material caused by the early closing of the valve by flushing. Under the condition that the discharge pressure is the same, the larger the pipe diameter, the more flushing, which is easy to affect the discharge accuracy, so the discharge branch pipes 301 with different diameters are connected to the discharge collecting pipe 4.

[0035] For example, when the thickest discharge branch pipe 301 discharges 80% of the total amount of material, part of the flushing material flows out, then the second thickest discharge branch pipe 301 discharges 80% of the remaining material, part of the flushing material flows out, and then the third thickest discharge branch pipe 301 discharges 80% of the remaining material, part of the flushing material flows out. In this embodiment, three discharge branch pipes 301 are taken as an example, and when the thinnest discharge branch pipe 301 discharges, 90%-95% of the remaining material can be discharged through the thinnest discharge branch pipe 301, and a small amount of flushing material is used to increase the accuracy of the discharge.

[0036] ​In conclusion, the utility model discloses a mixing tank 1 is arranged obliquely, and the uniformity and the mixing rate of mixing are increased by adding other flow directions except the stirring of the internal raw materials in the stirring part 2, and the raw materials in the mixing tank 1 are directly discharged by the discharge collecting pipe 4 arranged on the oblique side, so that the container for mixing does not need to be opened to pour, and the direct contact of all raw materials and external air during discharging and a large amount of bubbles generated during pouring are avoided.The discharge branch pipes 301 are arranged, the inner diameters of the discharge branch pipes 301 are different, the discharge branch pipes 301 are segmented by the inner diameters from big to small, the discharge amount of the discharge branch pipes 301 is reduced, and the discharging precision of the raw materials is increased.The air pressure adjusting pipe 8 is connected with the vacuum pump or the air compressor, bubbles are removed during mixing, the quality of the raw materials is increased, the air compressor pressurizes the mixing tank 1, and the discharge is assisted, and the discharge is more favorable.

[0037] The electrical components in the present disclosure are connected with the main controller and 220V mains, and the PLC control system is a conventional device known by those skilled in the art, and the detailed description of the known functions and known components is omitted in the specific embodiment of the present disclosure.

[0038] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
