Description

Technical Field

[0001] The utility model relates to raw material mixing equipment, in particular to a multi-liquid mixing device. Background Art

[0002] Styrene is an oily liquid with a certain viscosity. During use, other raw materials need to be mixed into it to reduce its viscosity on the one hand and dilute it on the other.

[0003] The current mixing equipment uses electric mechanical devices to stir, and the raw materials are added directly from the mouth of the stirrer. When the temperature of styrene rises to a certain condition (about 50°C or above), it will polymerize to produce polystyrene. The existing electric mechanical devices cause the raw materials in the stirrer to rub against its inner wall, and the temperature of the motor is transmitted to the raw materials, which can easily cause the raw materials to heat up and cause styrene polymerization. Utility Model Content

[0004] In view of the technical problem in the prior art that mixing raw materials and styrene by an electric mechanical device easily leads to an increase in the temperature of styrene and the raw materials, the utility model provides a multi-liquid mixing device, which has the advantages of being able to fully mix without causing changes in the temperature of the material and styrene.

[0005] The technical solution of the utility model is:

[0006] A multi-liquid mixing device, comprising:

[0007] A container, the interior of which is a mixing section;

[0008] A plurality of conduits are distributed in a ring shape on the container, one end of the conduit is horizontally placed at the bottom of the mixing section, and the end of the conduit has a plurality of small holes;

[0011] Optionally, the small hole on the feeding pipe is a feeding hole, and the flow direction of the fluid output from the feeding hole is arranged along the vertical direction.

[0012] Optionally, the feed pipe and the air feed pipe are spaced apart.

[0013] Optionally, all the air supply pipes are L-shaped, and one end thereof away from the air supply hole passes vertically upward from the middle of the container. All the air supply pipes are distributed in a ring shape and are tightly attached to each other, and a channel is formed in the middle, and a feeding pipe is provided in the channel.

[0014] Optionally, a sleeve is provided on one end of all the air supply pipes located in the middle of the container, a rotor is rotatably provided on the sleeve, and a plurality of blades are provided on the rotor.

[0015] Optionally, the paddle is an inclined structure, and the inclination direction of the paddle is opposite to the inclination direction of the air supply hole.

[0016] Optionally, the feeding tube is also L-shaped, and one end of the feeding tube away from the feeding hole is vertically arranged on the side wall of the container.

[0017] Optionally, the length of the feeding pipe at one end having the feeding hole is equal to 50%-70% of the length of the air feeding pipe at one end having the air feeding hole.

[0018] Optionally, one end of all the air supply pipes away from the air supply holes is connected to an air collecting pipe.

[0020] A plurality of conduits are arranged in the container, and a part of the conduits are set as feeding pipes for feeding raw materials into the container, and another part of the conduits are set as air guide pipes for feeding clean air into the container.

[0021] Since the small holes of all the conduits are distributed at the bottom of the container, it can be ensured that the air and raw materials can be evenly distributed in the container and mixed with the styrene in the container.

[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] Example:

[0031] See also Figure 1-Figure 3 , a multi-liquid mixing device, comprising a container 1 and a conduit. The container 1 in the present application is a cylindrical open structure, the interior of which is a mixing part, and styrene is stirred in the mixing part.

[0032] There are several conduits arranged in the container 1, one end of the conduit is laid on the bottom of the container 1, and the length direction of this end of the conduit is parallel to the bottom surface of the container 1. At the same time, this end of the conduit has several small holes.

[0033] It is assumed that one part of the conduit is a feeding tube 2 , and the small hole on the feeding tube 2 is a feeding hole 3 , and the other part is an air feeding tube 4 , and the small hole on the air feeding tube 4 is an air feeding hole 5 .

[0034] During operation, one end of the air supply pipe 4 away from the air supply hole 5 is connected to a clean air source to supply clean air to the bottom of the container 1 through the air supply pipe 4 and the air supply hole 5. One end of the feeding pipe 2 away from the feeding hole 3 is installed on the raw material output end to supply raw materials for mixing to the bottom of the container 1 through the feeding pipe 2 and the feeding hole 3, wherein different raw material pipes can be connected to different raw material output ends.

[0035] In this embodiment, styrene is put into the mixing part. Since the small holes of all the conduits are distributed at the bottom of the container 1, it can be ensured that the air and the raw materials can be evenly distributed in the container 1 and mixed with the styrene in the container 1.

[0036] Due to the buoyancy of the air, the air floats in the styrene and pushes the styrene and raw materials in the container 1 to move, thereby achieving the stirring effect. Since the temperature of the air is lower than the temperature at which styrene polymerizes, the polymerization of styrene can be effectively avoided.

[0037] In one specific embodiment:

[0038] The air supply holes 5 are arranged in an inclined shape on the air supply pipe 4. Specifically, the inclined shape means that there is an angle between the flow direction of the air flow output from the air supply holes 5 and the vertical plane, and the angle is between 45° and 60°. At the same time, the air supply holes 5 on all the air supply pipes 4 have the same inclination direction.

[0039] In this embodiment, all the air supply pipes 4 are evenly distributed around the axis of the container 1 , so the consistent inclination direction of all the air supply holes 5 mentioned above means that all the air supply holes 5 are directed in the same direction in the circumferential direction of the container 1 .

[0040] In this embodiment, by setting all the air supply holes 5 to an inclined structure, the styrene and raw materials in the mixing part can be caused to rotate around the axis of the container 1 during the process of supplying air, thereby improving the mixing efficiency.

[0041] In another specific embodiment:

[0042] The feeding hole 3 on the feeding pipe 2 is arranged along the vertical direction. The arrangement along the vertical direction mentioned here means that the flow direction of the liquid output from the feeding hole 3 is parallel to the axis of the container 1.

[0043] Since the gas output from the air supply hole 5 flows in an inclined direction, and the liquid flowing out of the feed hole 3 here is in a vertical direction, there is an angle between the flow direction of the air and the flow direction of the raw material. As a result, the raw material is dispersed in the styrene liquid under the action of the air flow, thereby improving the mixing effect.

[0044] In another specific embodiment:

[0045] The air supply pipe 4 is L-shaped, and one end of the air supply pipe 4 having the air supply hole 5 is laid at the bottom of the container 1, and the other end of the air supply pipe 4 is located in the middle of the container 1 and extends upward along the axis of the container 1. All the air supply pipes 4 are evenly distributed around the axis of the container 1, and the ends of all the air supply pipes 4 extending upward are distributed in a ring shape, and two adjacent air supply pipes 4 are close to each other, so that the ends of all the air supply pipes 4 form a channel in the middle of the container 1, and a feeding pipe 6 is arranged in the channel. The end of the air supply pipe 4 away from the air supply hole 5 is connected to a collecting pipe, and air is uniformly supplied to all the air supply pipes 4 through the collecting pipe.

[0046] In this embodiment, all air supply pipes 4 are evenly arranged at the bottom of the container 1, so that the air can be evenly distributed in the container 1, and the raw materials and styrene in the mixing part are evenly stirred. In addition, a feed pipe 6 is provided, through which the raw materials can be fed into the middle of the container 1, thereby improving the feeding efficiency of the raw materials.

[0047] Preferably, the feed pipe 2 is also an L-shaped structure, and one end of the feed pipe 2 is laid on the bottom of the container 1, and the other end is close to the outer wall of the container 1 and extends upward in the vertical direction. In addition, all the feed pipes 2 and all the air pipes 4 are arranged one by one, and the length of the end of the feed pipe 2 laid on the bottom of the container 1 is equal to 50%-70% of the length of the end of the air pipe 4 laid on the bottom of the container 1.

[0048] By arranging the feed pipe 2 and the air delivery pipe 4 in the middle and outside of the container 1 respectively, the rotation of the styrene and the raw material in the mixing section is facilitated. At the same time, the length of the feed pipe 2 is reduced to match the use of the feed pipe 6.

[0049] In another specific embodiment:

[0050] A sleeve 7 is sleeved on one end of all the air supply pipes 4 located in the middle of the container 1. A rotor is rotatably sleeved on the outside of the sleeve 7, and a plurality of blades 8 (at least three) are arranged on the circumference of the rotor.

[0051] When the air in the air supply pipe 4 is filled into the container 1, the air flows in an inclined direction and thus can impact the paddle 8, and cause the paddle 8 and the rotor to rotate on the sleeve 7, thereby enhancing the stirring force through the rotation of the paddle 8.

[0052] In another specific embodiment:

[0053] The blade 8 is an inclined structure, and the inclination direction of the blade 8 is opposite to the inclination direction of the air supply hole 5. By setting the blade 8 as an inclined structure, the force of the air output from the air supply hole 5 on the blade 8 can be increased, thereby increasing the rotation speed of the blade 8.

[0054] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
