Description

Technical Field

[0001] This utility model relates to the field of material mixing equipment technology, and in particular to a mixing device that can realize lifting and lowering of material feeding. Background Technology

[0002] Traditional mixing devices typically suffer from the following technical problems during the feeding process, especially when feeding below the liquid level:

[0003] The feed inlet is often fixed on the side of the mixing container. Since the fixed feed inlet is submerged below the liquid level for a long time, high-viscosity materials (such as glue and slurry) are prone to deposit and solidify at the inlet, which can easily cause the feed inlet to be blocked and require frequent shutdowns for cleaning.

[0004] Moreover, the material mixing uniformity is poor: the mixing container is located on the side and feeds in a single port, which easily causes local accumulation of materials. It is necessary to extend the mixing time to achieve uniform mixing, which affects the mixing efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a stirring device that can realize lifting and lowering of material feeding.

[0006] The technical solution of this utility model is as follows: it includes: a mixing container with a through-type feeding channel at the top; a driving device with its output end connected to the mixing shaft inside the mixing container; a feeding mechanism including: a liftable feeding pipe passing through the feeding channel; a lifting component driving the feeding pipe to move up and down between the feeding working position and the clearance position; and a support component for supporting the feeding pipe and the lifting component.

[0007] The feeding working position is where the outlet of the feeding pipe is located below the liquid level in the mixing container, and the clearance position is where the outlet of the feeding pipe is raised to the position above the liquid level.

[0008] A further technical solution is that the outlet of the feed pipe is equipped with a three-way connector to realize branched feeding.

[0009] A further technical solution is to include a limiting component set on the feed tube to limit the downward stroke of the feed tube.

[0010] A further technical solution is that the limiting component includes a limiting ear and a corresponding limiting pin on the feed pipe. When the feed pipe is in the feeding working position, the limiting pin abuts against the top of the mixing container.

[0011] The further technical solution is: the limiting ears are provided in two sets, the two sets of limiting ears are symmetrically distributed on both sides of the feed pipe along the radial direction, and the two sets of limiting pins are respectively inserted into the corresponding limiting ears.

[0012] A further technical solution is as follows: the lifting assembly includes a hoist, the upper lifting part of the hoist is movably connected to the support assembly, and the lower hook part is connected to the feed pipe.

[0013] A further technical solution is that the lifting assembly includes a servo electric cylinder, and the piston rod of the servo electric cylinder is rigidly connected to the feed pipe.

[0014] A further technical solution is that the support assembly includes a support frame fixed to the top of the mixing container.

[0015] A further technical solution is that the support component includes a support frame independent of the stirring container.

[0016] A further technical solution is that the feed pipe is provided with multiple sets, and the multiple sets of independent feed pipes correspond to the feed channels distributed on the top of the mixing container.

[0017] The beneficial technical effects of this utility model are:

[0018] The feed pipe is designed with a lifting mechanism: during feeding, the feed pipe descends to below the liquid level, and after feeding is completed, it is raised to above the liquid level (avoidance position), which avoids material contact with the pipe opening and solves the problem of feed port blockage.

[0019] The three-way connector enables dual-path symmetrical discharge, forming a counter-flow field, shortening the mixing time and improving the mixing efficiency.

[0020] By using multiple sets of feed pipes in tandem, multiple feeding points are used to avoid excessively high local concentrations and improve the uniformity of mixing. Attached Figure Description

[0025] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] like Figure 1 As shown, the present invention discloses a stirring device capable of lifting and lowering the material feed, used for feeding material at a liquid level. It includes a stirring container 1, a driving device 2, and a feeding mechanism 3 disposed on the top of the stirring container 1. The driving device 2 includes a driving motor and a reducer located at the output end of the driving motor. The output end of the reducer is connected to the stirring shaft through a coupling. Under the drive of the driving motor, the stirring shaft realizes the stirring of the material in the stirring container 1.

[0027] Specifically, the top of the mixing container 1 is provided with a sealing cover, and a through-type feeding channel 4 is provided on the sealing cover.

[0028] like Figure 2 and Figure 3 As shown, the feeding mechanism 3 includes a support assembly, a feeding pipeline assembly, and a lifting assembly. The support assembly supports the feeding pipeline assembly and the lifting assembly. In this embodiment, the support assembly is a support frame 31, which is fixed to the top of the mixing container 1. The support frame 31 adopts a high-strength stainless steel frame structure to support the feeding pipeline assembly and the lifting assembly. The support assembly can also be a support frame and set independently of the mixing container 1.

[0029] The feed line assembly is used to realize feeding, including a feed hose and a liftable feed pipe 32. The feed hose is connected to an external feeding system. The feed pipe 32 passes through the feed channel 4 and forms an airtight connection with the feed channel 4 through a conical silicone ring. The lower end of the feed pipe 32 is provided with a discharge port.

[0030] In this embodiment, to ensure uniform material distribution, the outlet of the feed pipe 32 is equipped with a three-way connector 33 for split feeding. Simultaneously, the dual outlet diversion reduces the single-outlet discharge rate, resulting in a gentler shear rate and preventing the destruction of active ingredients due to high shear rates. The dual-outlet design generates a secondary flow to compensate for the discharge rate, achieving more efficient macroscopic material mixing.

[0031] In this embodiment, the lifting assembly is used to drive the feed pipe 32 to move up and down between the feeding station and the clearance station. The feeding station is the position where the outlet of the feed pipe 32 extends below the liquid surface of the mixing container 1, and the clearance station is the position where the feed pipe 32 is raised above the liquid surface, so as to avoid obstruction for the driving device 2 to drive the mixing shaft to mix materials. Specifically, the lifting assembly includes a hoist 34, the upper lifting part of the hoist 34 is movably connected to the crossbeam of the support frame 31, and the lower hook part of the hoist 34 is detachably connected to the lifting lug 35 on the feed pipe 32.

[0032] Preferably, the hoist 34 is a manual chain hoist, which is easy to operate manually, realizes rapid lifting and lowering of the feed pipe 32, and has low installation and maintenance costs.

[0033] Furthermore, the feeding mechanism 3 also includes a limiting component, which is used to control the lifting stroke of the feeding pipe 32. Specifically, the limiting component includes a limiting ear 36 disposed on the feeding pipe 32 and a limiting pin 37 passing through the limiting ear 36. When the feeding pipe 32 descends to the feeding position, the limiting pin 37 abuts against the sealing cover at the top of the mixing container 1 to ensure that the feeding position is in the set position.

[0034] To ensure the stable positioning of the feed pipe 32, two sets of limiting ears 36 are provided. The two sets of limiting ears 36 are symmetrically distributed on both sides of the feed pipe 32 along the radial direction, and are respectively inserted into the corresponding limiting ears 36 by two sets of limiting pins 37.

[0035] In another embodiment, the lifting assembly can be driven by a servo electric cylinder, which is fixed on the crossbeam of the support frame 31. The piston rod of the servo electric cylinder is rigidly connected to the feed pipe 32, and the precise lifting control of the feed pipe 32 is achieved through a displacement sensor.

[0036] In this embodiment, the feed pipeline assembly is provided with multiple sets, and the multiple sets of feed pipes 32 correspond to several feed channels 4 evenly distributed on the sealing cover. The multiple sets of independent feed pipes 32 better achieve the uniform distribution of materials.

[0037] The structure features an innovative lifting feed pipe 32 design: during feeding, the feed pipe 32 descends to the working position and feeds the material at the liquid level; after feeding is completed, the feed pipe 32 rises above the liquid level to avoid contact with the material, while the drive device 2 drives the stirring shaft to stir the material.

[0038] Compared to traditional mixing devices, the feed inlet is usually fixed on the side wall of the mixing container 1 and is submerged below the liquid level for a long time. The material is prone to deposit and solidify at the feed inlet, causing pipe blockage. In particular, high-viscosity materials are very likely to form on the wall at the feed inlet and block the pipe. Therefore, it is necessary to stop the machine regularly for cleaning and maintenance, which greatly increases the maintenance difficulty and affects efficiency.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
