Description

Technical Field

[0001] This utility model relates to the field of mixing technology, and in particular to a stirring and discharging guide device. Background Technology

[0002] In industrial production, mixers are the core equipment for mixing materials. They often need to be transported to containers or equipment for subsequent processes through guide pipes. The connection structure between the guide pipe and the mixer outlet directly affects the ease of use, sealing performance, and maintenance efficiency of the equipment. The traditional connection method generally adopts a flange connection structure, which involves setting flanges at the mixer outlet and one end of the guide pipe, fastening the two flanges together with bolts, and setting a sealing ring between the flange contact surfaces to achieve a seal.

[0003] Traditional flange connections require the use of wrenches and other tools to tighten or loosen bolts one by one. For industries such as food processing and pharmaceutical manufacturing that require frequent cleaning of the guide pipe, the guide pipe must be disassembled for sterilization or impurity removal before and after each production run, which is particularly time-consuming. In order to avoid cross-contamination between different batches of materials, the inner wall of the guide pipe must be thoroughly cleaned after each mixing operation. The bolt disassembly and assembly process of the flange seriously affects the turnover efficiency of the production line, thereby reducing disassembly efficiency and increasing the workload of the staff. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a mixing and discharging guide device that can solve the problem that the guide pipe needs to be disassembled for sterilization or impurity removal before and after each production, which is particularly time-consuming. In order to avoid cross-contamination of different batches of materials, the inner wall of the guide pipe needs to be thoroughly cleaned after each mixing operation. The bolt disassembly and assembly process of the flange seriously affects the turnover efficiency of the production line, thereby reducing the disassembly efficiency and increasing the workload of the staff.

Protrusions are fixedly connected to the outer walls of both the upper and lower clamps away from the fixing seats.

[0007] The inner walls of both the lower and upper clamps are fixedly equipped with protective pads. The outer wall of the upper protrusion of the upper clamp is threaded with two fixing bolts. The outer wall of the upper protrusion of the lower clamp is provided with a positioning groove. The outer wall of the upper protrusion of the upper clamp is fixedly connected with a positioning slide.

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] Example 1: Reference Figure 1-3 A standard implementation of a flow guide connection (positioning slider + rubber protective pad).

[0030] Suitable for guiding and connecting common materials (such as aqueous solutions and low-viscosity slurries), the discharge pipe and the guide pipe are stably sealed through the basic clamp assembly.

[0031] Structural features: The positioning slider 5 uses ordinary plastic positioning slider, which slides in conjunction with the positioning groove 11 of the lower clamp 7. The protective pad 9 is made of nitrile rubber, which fits the pipe connection. The upper clamp can be fixed by manually tightening the fixing bolt.

[0032] Connection effect: After the clamp is closed, the rubber protective pad fills the gap in the pipe, and the positioning slider ensures that the upper clamp and the lower clamp are aligned. It is suitable for the discharge of daily mixing equipment, such as food processing and general chemical raw material transportation. It is easy to install and disassemble and has low maintenance costs.

[0033] Example 2: Reference Figure 4 High-pressure material conveying sealing embodiment (trapezoidal positioning slider + metal spiral wound pad)

[0034] For high-pressure operating conditions, the sealing performance is improved by using a trapezoidal positioning slider and a metal spiral wound gasket.

[0035] Structural features: The positioning slide is replaced with a trapezoidal positioning slider (aluminum alloy material), which enhances the stability of the clamp by using the wedge action of the trapezoidal surface and the slide groove. The protective pad is upgraded to a metal spiral wound pad (stainless steel + graphite composite layer), which can withstand higher pressure and temperature.

[0036] High-pressure scenario performance: The trapezoidal slider provides additional axial pressure, and the metal spiral wound gasket maintains good sealing performance under high pressure to prevent material leakage. It is suitable for high-pressure conveying scenarios such as petrochemicals and sewage treatment, and can resist the impact of particles in slurry, extending the service life of the clamp.

[0037] Furthermore, when using this device, align the T-shaped slider 15 of the guide tube 2 with the T-shaped slider groove 10 of the discharge tube 1, and push the guide tube 2 axially so that the T-shaped slider 15 slides completely into the groove (at this time, one end of the guide tube 2 is inserted into the discharge tube 1, and the axes of the two coincide). During this process, the sealing ring 8 on the outer wall of the guide tube 2 is squeezed between the inner walls of the two tubes, initially forming a seal. Then, flip the upper clamp 3 (rotate around the hinge of the fixed seat 12 and the connecting seat 14) so ​​that the upper clamp 3 and the lower clamp 14 are aligned. The clamps 7 form a complete ring and fit over the outer wall of the connection between the discharge pipe 1 and the guide pipe 2. At this time, the positioning slider 5 (positioning slider or magnetic positioning slider 13) on the upper clamp 3 protrusion 6 slides into the positioning groove 11 of the lower clamp 7 protrusion 6. If it is a positioning slider, the bolt holes of the upper and lower protrusions 6 are precisely aligned with the groove through sliding cooperation. If it is a magnetic positioning slider 13, the slider is attracted to the magnetic seat by magnetic force, realizing the pre-fixation of the protrusion 6 and avoiding misalignment during the closing process. Next, tighten the two fixing bolts 4 on the upper clamp 3 protrusion 6 so that the bolt ends screw into the corresponding grooves of the lower clamp 7 protrusion 6 until the bolt heads press against the surface of the protrusion 6. At this time, the upper clamp 3 and the lower clamp 7 generate a uniform clamping force in the circumferential direction, which clamps the connection between the discharge pipe 1 and the guide pipe 2 through the protective pad 9 on the inner wall, further compressing the sealing ring 8 to ensure reliable sealing. At the same time, the cooperation between the T-shaped slider 15 and the T-shaped slider groove 10 restricts the axial and circumferential displacement of the two pipes. The body forms a stable material conveying channel. When separating the discharge pipe 1 and the guide pipe 2, the fixing bolt 4 is turned in the opposite direction so that its end is disengaged from the groove of the protrusion 6 of the lower clamp 7, releasing the locking force. Then, the upper clamp 3 is flipped (rotated upward around the hinge) to separate the upper and lower clamps, releasing the clamping constraint on the pipe connection. Then, the guide pipe 2 is pulled axially so that the T-shaped slider 15 slides out along the T-shaped slider groove 10, realizing the separation of the guide pipe 2 and the discharge pipe 1, which is convenient for individual cleaning or replacement of parts.

[0038] With the hinged flip-type clamp structure in the clamp assembly, the upper clamp 3 and the lower clamp 7 form an openable semi-ring combination through the fixed seat 12 and the connecting seat 14. There is no need to align multiple bolt holes. The clamp can be closed and separated by simply flipping the upper clamp with one hand. The protrusion at the free end of the clamp is designed with a positioning slide 5 and a positioning groove 11. Pre-positioning is achieved through sliding cooperation or magnetic attraction to avoid positional deviation during locking. This allows the operator to quickly align the connection point without repeated adjustments. With the butterfly fixing bolt that can be turned by hand, the entire disassembly and assembly process does not require the use of wrenches or other tools, which greatly simplifies the operation process and significantly shortens the equipment maintenance time. It is especially suitable for the high-frequency pipeline cleaning needs before and after batch production in the food and pharmaceutical industries, and effectively reduces the downtime of the production line caused by disassembly and assembly.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
