Abstract
Description
Technical Field
[0001] This utility model relates to material mixing equipment, and in particular to a pull-out type twin-shaft paddle mixer. Background Technology
[0002] Currently, there are many types of stationary container mixing equipment, including ribbon mixers, plow mixers, twin-shaft paddle mixers, and conical mixers. Among them, horizontal mixing equipment includes horizontal ribbon mixers, plow mixers, and twin-shaft paddle mixers.
[0003] One problem with these mixing devices is that the cleaning effect is not directly visible when changing materials, as the agitator obstructs the view, leading to poor cleaning results. Furthermore, maintenance of the agitator often requires workers to enter the confined space, which poses a risk of injury. Currently, none of these stationary container devices allow for the removal of the agitator without disassembling the container.
[0004] Therefore, there is an urgent need for a new type of equipment that is easier to clean and maintain. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of existing container-fixed mixing equipment, which cannot remove the mixing components without disassembling the cylinder, resulting in poor cleaning effect and easy injury to workers during maintenance. The present invention provides a pull-out twin-shaft paddle mixer.
[0006] The present invention solves the above-mentioned technical problems through the following technical solution:
[0007] A pull-out type twin-shaft paddle mixer is characterized in that it includes a stirring shell, a sliding end cover component, a stirring mechanism, and a slide rail structure. An insertion port is provided on one side of the stirring shell, through which the stirring mechanism passes and is rotatably connected to the sliding end cover component. The stirring mechanism is connected to the slide rail structure and can move on the slide rail structure, having a stirring state and a disassembled state.
[0008] In the stirring state, the stirring mechanism passes through the insertion port and is inserted into the stirring housing, and the sliding end cap component is detachably connected to the stirring housing and seals and covers the insertion port;
[0009] In the disassembled state, the sliding end cap component is detached from the stirring housing, and the stirring mechanism is exposed outside the stirring housing.
[0010] In this design, the aforementioned structural form allows the stirring mechanism to move along the slide rail structure, enabling it to be pulled out of the mixing shell. This facilitates thorough cleaning of material residue in the dead corners of the stirring mechanism and provides convenience for maintenance. It effectively solves the problems of difficult cleaning of material residue in the dead corners and the difficulty of maintenance of the stirring mechanism. Furthermore, after the stirring mechanism is pulled out of the mixing shell, the internal dead corners of the mixing shell are no longer obstructed, making cleaning easier and providing space for subsequent maintenance work that needs to be performed inside the mixing shell. This significantly improves the safety of the pull-out twin-shaft paddle mixer.
[0011] Preferably, the pull-out twin-shaft paddle mixer further includes a frame, on which the slide rail structure and the mixing shell are both mounted, and the slide rail structure corresponds to the insertion port.
[0012] In this design, the aforementioned structural form is adopted, with the stirring mechanism mounted on the slide rail structure. Both the slide rail structure and the stirring shell are mounted on the frame, ensuring stable overall operation of the stirring mechanism and stirring shell during high-power operation. Simultaneously, this allows for a unified installation, reducing the commissioning work required after moving the pull-out twin-shaft paddle mixer.
[0013] Preferably, the stirring mechanism includes a base, a drive motor, a reducer, and a main shaft component. The base is slidably connected to the slide rail structure. The drive motor and the reducer are both connected to the base. The two ends of the reducer are respectively connected to the output end of the drive motor and the main shaft component. The main shaft component passes through and is rotatably connected to the sliding end cover component.
[0014] In this solution, the above-mentioned structural form is adopted. The base is slidably connected to the slide rail structure, and the drive motor and reducer are both connected to the base to achieve the load-bearing capacity. It has the characteristics of large transmission load, smooth operation and high efficiency.
[0015] Preferably, the main shaft component includes a first main shaft, a second main shaft, a plurality of first blades, and a plurality of second blades. The first main shaft and the second main shaft are both connected to the reducer, and the first main shaft and the second main shaft rotate in opposite directions. The plurality of first blades and the plurality of second blades are respectively connected to the outer surfaces of the first main shaft and the second main shaft. The plurality of first blades are used to push the material to move radially along the main shaft component, and the plurality of second blades are used to push the material to move axially along the main shaft component.
[0016] In this design, the aforementioned structure is employed. Driven by a motor and reducer, the first and second main shafts rotate in opposite directions, causing the material within the mixing shell to undergo convective mixing under the action of the first and second main shafts, resulting in excellent mixing performance. Simultaneously, both the first and second main shafts are equipped with multiple first blades and multiple second blades. The first blades propel the material radially along the main shaft components, while the second blades propel the material axially along the main shaft components. Within the mixing shell, the material circulates through diffusion and convection under the combined action of the blades at different angles, ultimately achieving the desired mixing requirements.
[0017] Preferably, a split bearing is provided between the spindle component and the sliding end cover component;
[0018] And / or, a sealing device is provided between the spindle component and the sliding end cap component.
[0019] In this solution, the above-mentioned structural form is adopted, and the split bearing is mounted on the sliding end cover component to support the main shaft component and bear the load movement.
[0020] In addition, by placing the sealing device between the main shaft component and the sliding end cover component to achieve a sealing effect, leakage during the mixing process of various powder materials can be effectively prevented; at the same time, the sealing element, which can adapt to various rotary motion, reciprocating motion and spiral motion, can better prevent dust leakage and maintain the durability of the sealing structure.
[0021] Preferably, the slide rail structure includes multiple guide rails and multiple sliders, the multiple guide rails are arranged in parallel on the frame, the multiple sliders are all connected to the bottom surface of the base, and the multiple sliders are respectively connected to the multiple guide rails.
[0022] In this solution, the aforementioned structural form is adopted, in which the stirring mechanism is slidably mounted on multiple guide rails via multiple sliders, thereby enabling the stirring mechanism and the sliding end cap component to move stably to the stirring state or the disassembled state. Furthermore, the use of guide rails and sliders simplifies the overall structure and reduces cost.
[0023] Preferably, the pull-out dual-shaft paddle mixer further includes a water tank component, which is disposed within the frame, and in the disassembled state, the main shaft component is located directly above the water tank component.
[0024] In this solution, the above-mentioned structural form is adopted so that the debris generated during the cleaning or maintenance of the spindle component can be collected in the water tank component, which facilitates the centralized treatment of cleaning material residue.
[0025] Preferably, the pull-out twin-shaft paddle mixer further includes a stop block connected to the frame, and the stop block is located at the end of the slide rail structure away from the mixing shell. The side of the stop block facing the slide rail structure is provided with a buffer pad for abutting against the mixing mechanism.
[0026] In this design, the aforementioned structural form is adopted. The baffle blocks the stirring mechanism, effectively preventing it from detaching from the slide rail structure, thus ensuring high safety and reliability. The buffer pad provides cushioning, causing the stirring mechanism to impact against it during movement, further enhancing the safety of the pull-out twin-shaft paddle mixer.
[0027] Preferably, the pull-out twin-shaft paddle mixer further includes a safety detection component, which is disposed between the sliding end cover component and the stirring housing, and is electrically connected to the stirring mechanism.
[0028] In this solution, using the aforementioned structural form, the safety detection component will send a signal and control the stirring mechanism to stop when it detects the separation of the sliding end cover component from the stirring shell, thereby ensuring operational safety. Furthermore, the stirring mechanism can only perform stirring operations when the stirring shell and the sliding end cover component are connected and the safety detection component is triggered.
[0029] Preferably, the outer surface of the stirring shell has a plurality of locking elements, all of which are detachably connected to the sliding end cap component;
[0030] And / or, the outer surface of the stirring shell has a transparent observation window.
[0031] In this solution, the above-mentioned structure is adopted, and multiple locking components are used to lock and connect the sliding end cover component, thereby achieving a sealed connection between the sliding end cover component and the stirring shell and sealing and covering the insertion port.
[0032] In addition, the transparent observation window allows for observation of the inside of the mixing shell, facilitating personnel monitoring.
[0033] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.
[0034] The positive and progressive effects of this utility model are as follows:
[0035] This utility model discloses a pull-out twin-shaft paddle mixer. The stirring mechanism can move along a slide rail structure, allowing it to be pulled out of the mixing shell when disassembled. This facilitates thorough cleaning of material residue in the dead corners of the stirring mechanism and provides convenience for maintenance. Furthermore, with the stirring mechanism pulled out of the mixing shell, the internal dead corners of the mixing shell are no longer obstructed, making cleaning easier and providing space for subsequent maintenance work that needs to be performed inside the mixing shell. This significantly improves the safety of the pull-out twin-shaft paddle mixer. Attached Figure Description

[0063] The present invention will be described more clearly and completely below by way of embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments described below.
[0064] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment discloses a pull-out type twin-shaft paddle mixer, which includes a stirring shell 1, a stirring mechanism 2, a sliding end cap component 3, and a slide rail structure 4. An insertion port is provided on one side of the stirring shell 1, through which the stirring mechanism 2 passes and is rotatably connected to the sliding end cap component 3. The stirring mechanism 2 is connected to the slide rail structure 4 and can move on the slide rail structure 4, having a stirring state and a disassembled state. In the stirring state, the stirring mechanism 2 passes through the insertion port and is inserted into the stirring shell 1, and the sliding end cap component 3 is detachably connected to the stirring shell 1 and seals and covers the insertion port. In the disassembled state, the sliding end cap component 3 is disassembled from the stirring shell 1, and the stirring mechanism 2 is exposed outside the stirring shell 1.
[0065] This embodiment of the pull-out twin-shaft paddle mixer is mainly used for material mixing in the food and pharmaceutical industries. In the mixing state, the sliding end cap 3 is connected to the mixing housing 1 and seals the insertion port. Material is placed into the mixing housing 1, and the mixing mechanism 2 located inside the mixing housing 1 mixes the material. In the disassembled state, the sliding end cap 3 and the mixing housing 1 are detached. The mixing mechanism 2 can move on the slide rail structure 4, allowing it to be pulled out of the mixing housing 1. This facilitates thorough cleaning of material residue in the dead corners of the mixing mechanism 2 and provides convenience for maintenance. It effectively solves the problems of difficulty in cleaning material residue in the dead corners of the mixing mechanism 2 and the difficulty in maintenance of the mixing mechanism 2. Simultaneously, after the mixing mechanism 2 is pulled out of the mixing housing 1, the internal dead corners of the mixing housing 1 are no longer obstructed, making cleaning easier and providing space for subsequent maintenance work that needs to be performed inside the mixing housing 1, greatly improving the safety of the pull-out twin-shaft paddle mixer.
[0066] In this embodiment, the pull-out twin-shaft paddle mixer also includes a frame 5, with a slide rail structure 4 and a mixing shell 1 both mounted on the frame 5, and the slide rail structure 4 corresponding to the insertion port. The mixing mechanism 2 is mounted on the slide rail structure 4, and both the slide rail structure 4 and the mixing shell 1 are mounted on the frame 5, ensuring stable overall operation of the mixing mechanism 2 and the mixing shell 1 during high-power operation. Simultaneously, the entire assembly is installed together, reducing the debugging work required after moving the pull-out twin-shaft paddle mixer.
[0067] The stirring mechanism 2 includes a base 21, a drive motor 22, a reducer 23, and a main shaft assembly 24. The base 21 is slidably connected to the slide rail structure 4. Both the drive motor 22 and the reducer 23 are connected to the base 21. The two ends of the reducer 23 are respectively connected to the output end of the drive motor 22 and the main shaft assembly 24. The main shaft assembly 24 passes through and is rotatably connected to the sliding end cover assembly 3. The drive motor 22 provides driving force, which is applied to the main shaft assembly 24 through the reducer 23 to drive its rotation. The slidable connection to the slide rail structure 4 via the base 21, along with the drive motor 22 and reducer 23, enables it to bear heavy loads, providing high load capacity, smooth operation, and high efficiency. The drive motor 22 and reducer 23 are flange-connected and can be seated on the sliding end cover assembly 3, and are bolted together.
[0068] like Figure 2 and Figure 3As shown, the main shaft component 24 includes a first main shaft 241, a second main shaft 242, a plurality of first blades 243, and a plurality of second blades 244. The first main shaft 241 and the second main shaft 242 are both connected to the reducer 23, and the rotation directions of the first main shaft 241 and the second main shaft 242 are opposite. The plurality of first blades 243 and the plurality of second blades 244 are respectively connected to the outer surfaces of the first main shaft 241 and the second main shaft 242. The plurality of first blades 243 are used to push the material to move radially along the main shaft component 24, and the plurality of second blades 244 are used to push the material to move axially along the main shaft component 24. The main shaft assembly 24 is installed inside the mixing shell 1 with a certain gap. The first main shaft 241 and the second main shaft 242 are inserted into the reducer 23. Driven by the drive motor 22 and the reducer 23, the first main shaft 241 and the second main shaft 242 rotate in opposite directions, thereby causing the material inside the mixing shell 1 to undergo convective mixing under the action of the first main shaft 241 and the second main shaft 242, resulting in good mixing effect. At the same time, the first main shaft 241 and the second main shaft 242 are each equipped with multiple first blades 243 and multiple second blades 244. The multiple first blades 243 are used to push the material to move radially along the main shaft assembly 24, and the multiple second blades 244 are used to push the material to move axially along the main shaft assembly 24. Under the combined action of the blades at different angles inside the mixing shell 1, the material undergoes diffusion and convection circulation, ultimately achieving the predetermined mixing requirements.
[0069] The main shaft is equipped with a certain number of blades at a certain angle to each other. When the blades reach a certain circumferential speed, the material is thrown up by the strong action of the plow blades. Part of the material moves in a circular motion along the cylinder wall, while the other part of the material is thrown towards the center of the mixing shell 1 or scattered and circulated towards both ends of the mixing shell 1 along the normal direction of the plow wall, and finally achieves the predetermined mixing requirements.
[0070] A sealing device 31 is provided between the main shaft component 24 and the sliding end cover component 3. By placing the sealing device 31 between the main shaft component 24 and the sliding end cover component 3, a sealing function is achieved, which can effectively prevent leakage during the mixing process of various powder materials. At the same time, the sealing element, which can adapt to various rotary, reciprocating, and helical motions, can better prevent dust leakage and maintain the durability of the sealing structure. The sealing device 31 can be composed of packing seals, oil ring seals, etc., and the specific structure is not limited.
[0071] A split bearing 32 is provided between the main shaft assembly 24 and the sliding end cover assembly 3. The split bearing 32 is mounted on the sliding end cover assembly 3 to support the main shaft assembly 24 and bear the load movement. The stirring mechanism 2 and the stirring housing 1 are connected to the frame, and the reducer 23 and the main shaft assembly 24 are all directly connected and matched with pedestal bearings to bear the load operation capacity, which has the characteristics of large transmission load, smooth operation and high efficiency.
[0072] The slide rail structure 4 includes multiple guide rails 41 and multiple sliders 42. The guide rails 41 are arranged parallel to each other on the frame 5, and the sliders 42 are all connected to the bottom surface of the base 21, and each slider 42 is connected to one of the guide rails 41. The stirring mechanism 2 is slidably mounted on the guide rails 41 via the multiple sliders 42, thereby enabling the stirring mechanism 2 and the sliding end cap component 3 to move stably to the stirring state or the disassembled state. At the same time, the use of guide rails 41 and sliders 42 simplifies the overall structure and reduces cost. The movement of the stirring mechanism 2 and the sliding end cap component 3 can be manually driven or automatically controlled by an electric drive mechanism or other similar methods.
[0073] The pull-out type twin-shaft paddle mixer also includes a water tank component 6, which is housed within the frame 5. In the disassembled state, the main shaft component 24 is located directly above the water tank component 6. When disassembled, the main shaft component 24 is pulled out from the mixing shell 1, allowing any debris generated during cleaning or maintenance of the main shaft component 24 to be collected in the water tank component 6 for convenient and centralized disposal of material residue. The mixing shell 1 has a discharge port at its bottom, and the water tank component 6 is located within the frame 5 and directly below the mixing shell 1, enabling the centralized disposal of debris generated during cleaning or maintenance of the mixing shell 1.
[0074] The pull-out twin-shaft paddle mixer also includes a stop block 7, which is connected to the frame 5 and located at the end of the slide rail structure 4 away from the mixing housing 1. A buffer pad 8 is provided on the side of the stop block 7 facing the slide rail structure 4 to abut against the mixing mechanism 2. The stop block 7 acts as a barrier against the mixing mechanism 2, effectively preventing it from detaching from the slide rail structure 4, ensuring high safety and reliability. The buffer pad 8 provides cushioning, causing the mixing mechanism 2 to impact against it during movement, further improving the safety of the pull-out twin-shaft paddle mixer.
[0075] The pull-out twin-shaft paddle mixer also includes a safety detection component 9, which is located between the sliding end cover component 3 and the mixing housing 1, and is electrically connected to the mixing mechanism 2. The safety detection component 9, installed between the mixing housing 1 and the sliding end cover component 3, will send a signal and control the mixing mechanism 2 to stop when it detects that the sliding end cover component 3 and the mixing housing 1 are separated, thus ensuring operational safety. Simultaneously, the mixing mechanism 2 can only perform mixing operations when the mixing housing 1 and the sliding end cover component 3 are connected and the safety detection component 9 is triggered. The safety detection component 9 can be a pin-type safety switch.
[0076] The outer surface of the stirring housing 1 has multiple locking elements 11, all of which are detachably connected to the sliding end cap component 3. The sliding end cap component 3 moves toward the stirring housing 1 and fits against the outer surface of the stirring housing 1, and is then locked in place by the multiple locking elements 11, thereby achieving a sealed connection between the sliding end cap component 3 and the stirring housing 1 and sealingly covering the insertion port. When disassembly is required, the multiple locking elements 11 are unlocked, allowing the sliding end cap component 3 to move away from the stirring housing 1.
[0077] The outer surface of the stirring shell 1 has a transparent observation window 12. The internal condition of the stirring shell 1 can be observed through the transparent observation window 12, facilitating personnel observation. The stirring shell 1 may include a cylinder and a top cover, with the cylinder and top cover connected by a flange. When the main shaft assembly 24 is under maintenance, the top cover can be removed for more direct identification of problems.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
