Description

Technical Field

[0001] The invention relates to the technical field of mixing and dissolving equipment, and in particular to an anti-clogging mixing and dissolving device for processing special medical food. Background Art

[0002] FSMP is the abbreviation of FSMP, which is usually in the form of food, such as gel food, porous food, powdered food, paste food, etc. For paste and liquid FSMP, mixing equipment is needed to evenly mix different food ingredients during processing, and mixing and stirring can also accelerate the dissolution of some soluble nutrients into the mixture to ensure that the prepared FSMP can fully provide the required nutrients for patients.

[0003] During the mixing process, special medical foods in liquid form such as pastes are mostly mixed by rotary stirring. For liquid foods with higher viscosity, due to the single stirring direction, the stirred food ingredients will also gather along the stirring direction, making it impossible to break up and mix them, and the ideal stirring effect cannot be achieved. Therefore, Chinese patent CN115634592A discloses an anti-clogging mixing and dissolving device for processing liquid special medical foods, comprising a lower tank and an upper tank installed on the top of the lower tank, the inner wall of the lower tank and the outer wall of the upper tank being movably connected by a sealed bearing, four stirring shovels are equidistantly arranged at the top of the upper tank, the bottom end of the stirring shovel extends into the lower tank, and a first rotating shaft is fixed to the top of each stirring shovel, and the two ends of the first rotating shaft are movably connected to the same mounting seat through bearings, and a driving mechanism for driving the first rotating shaft to rotate is provided at the outer end of the first rotating shaft.

[0004] The device installs vertical up and down plug rods in the middle of the bottom of the lower tank, so that the stirring shovel can scoop up the elastic cap and move it upward during the discharge process, and use the elastic cap to drive the plug rod to move upward. Since the elastic cap is made of rubber material, when the elastic cap is scooped up to a certain height by the stirring shovel, it will deform and fall off the stirring shovel, allowing the plug rod to move downward. Therefore, the downward moving plug rod and thick blade can be used to dredge the food raw materials blocked inside the discharge pipe, thereby achieving the effect of preventing blockage. However, the large area occupied by the plug rod and the thick blade results in a small discharge space, which is not conducive to the passage of paste-like substances, and the dredging frequency is low, and the dredging effect cannot be guaranteed.

DETAILED DESCRIPTION

[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figures 1 to 10 : A clogging-proof mixing and dissolving device for processing special medical food comprises a barrel 1 and a mixing chamber 11 arranged inside the barrel 1, the top of the mixing chamber 11 is connected to a feed pipe 12, the bottom of the mixing chamber 11 is connected to a discharge pipe 13, an upper blocking cover 121 and a lower blocking cover 131 for blocking the feed pipe 12 and the discharge pipe 13 are arranged on the barrel 1, the barrel 1 is located in the mixing chamber 11 and a stirring frame 2 is rotatably installed, a driving unit 3 for driving the stirring frame 2 to rotate is arranged outside the barrel 1, the axis of the discharge pipe 13 is vertically arranged, a discharge pipe 132 is coaxially installed in the discharge pipe 13, and the upper side of the discharge pipe 132 is opened. The mouth fits with the inner wall of the discharge pipe 13; the outer sleeve of the discharge pipe 13 is provided with a movable sleeve 4, the movable sleeve 4 is connected to the outer wall of the discharge pipe 132 inside the discharge pipe 13, and the movable sleeve 4 drives the discharge pipe 132 to reciprocate along the axis of the discharge pipe 13; a vertical sleeve 122 is provided on the feed pipe 12, the sleeve 122 extends to the inside of the discharge pipe 132, and a plurality of strip through holes 123 are provided at the bottom of the sleeve 122, and the strip through holes 123 are distributed at equal angles around the circumference of the sleeve 122, and an extension paddle 124 is hingedly installed on the top of the strip through hole 123, and the extension paddle 124 is expanded outward when the discharge pipe 13 reciprocates.

[0021] When the anti-clogging mixing and dissolving device for processing special medical food in the present application is in use, the staff adds raw materials into the mixing chamber 11 of the cylinder 1 through the feed pipe 12. At this time, the feed pipe 13 at the bottom of the cylinder 1 is blocked by the lower blocking cover 131. During processing, the upper blocking cover 121 blocks the feed pipe 12, and the driving unit 3 starts to drive the stirring frame 2 to rotate and mix and stir the raw materials in the mixing chamber 11 to fully dissolve them. After the processing is completed, the lower blocking cover 131 is removed and the feed pipe 13 is opened, and the mixed special medical food is discharged from the mixing chamber 11. The food is discharged from the discharge pipe 13 at the bottom of the mixing chamber 11. In the present embodiment, a discharge pipe 132 is coaxially arranged in the discharge pipe 13. The top opening of the discharge pipe 132 fits the inner wall of the discharge pipe 13. The vertical sleeve 122 arranged on the upper sealing cover 121 extends into the discharge pipe 13. The special medical food is discharged through between the discharge pipe 132 and the sleeve 122. There is enough space between the discharge pipe 132 and the sleeve 122 for the special medical food to pass through. The smooth inner walls of the discharge pipe 132 and the sleeve 122 are also beneficial to the discharge of the food. When the special medical food inside causes blockage during discharge, the discharge pipe 132 in this embodiment can reciprocate along the axial direction inside the discharge pipe 13 to vibrate the material, thereby discharging the blocked material. The discharge pipe 132 is connected to the movable sleeve 4 outside the discharge pipe 13, so that the discharge pipe 132 can be driven to reciprocate by the movable sleeve 4 outside the cylinder 1, and the material inside the cylinder 1 will not contact the impurities in the air. At the same time, an extended paddle 124 is hinged at the strip through hole 123 at the bottom of the sleeve 122. Under normal conditions, the extended paddle 124 is located in the strip through hole 123, keeping the outer wall of the sleeve 122 smooth and not affecting the movement of the material. When the material is blocked at the discharge pipe 13, the extended paddle 124 can be flipped outward around the hinge axis and protrude from the surface of the sleeve 122, thereby shifting the material when the discharge pipe 132 reciprocates and vibrates up and down, thereby clearing the blocked material.

[0022] In order to solve the problem of how the movable sleeve 4 is connected to the discharge pipe 132 outside the feed pipe 13 and drives the discharge pipe 132 to reciprocate in the vertical direction, the following features are specifically provided: The peripheral side of the discharge tube 13 is provided with a plurality of waist-shaped holes 133, which extend along the axial direction of the discharge tube 13, and are distributed at equal angles around the peripheral side of the discharge tube 13; a plurality of radially extending connecting rods 41 are provided in the movable sleeve 4, and the connecting rods 41 pass through the waist-shaped holes 133 and are connected to the outer wall of the discharge tube 132; a side strip 42 surrounding the peripheral side is provided at the bottom of the movable sleeve 4, and an outer bottom plate 134 surrounding the peripheral side is provided at the bottom of the discharge tube 13; the cam 31 of the driving unit 3 is located between the outer bottom plate 134 and the side strip 42, and the rotating axis of the cam 31 is perpendicular to the axis of the discharge tube 13, and the peripheral side of the cam 31 is in contact with the bottom of the side strip 42, and the rotation of the cam 31 drives the movable sleeve 4 and the discharge tube 132 to reciprocate in the vertical direction; the cam 31 is coaxially connected to the first gear 311, and the driving unit 3 also includes a rotary driver 32, and the working end of the rotary driver 32 is connected to the first gear 311 in a transmission manner to drive the cam 31 to rotate.

[0023] The movable sleeve 4 in this embodiment can be composed of multiple arc-shaped parts. The connecting rod 41 of the movable sleeve 4 is connected to the outer wall of the discharge pipe 132 by inserting into the waist-shaped hole 133 on the discharge pipe 13. The waist-shaped hole 133 guides the moving path of the connecting rod 41. The driving unit 3 drives the movable sleeve 4 to reciprocate in the vertical direction through the cam 31, thereby driving the discharge pipe 132 to move synchronously. The cam 31 is set between the side strip 42 of the movable sleeve 4 and the outer bottom plate 134 of the discharge pipe 13. The side strip 42 fits the peripheral side of the cam 31. When the cam 31 rotates, the bottom of the side strip 42 can be changed to rotate with the cam 31 The distance between the axes is achieved, so that the movable sleeve 4 can move back and forth in a straight line under the action of gravity and the thrust of the cam 31, driving the discharge pipe 132 to vibrate in the vertical direction to clear the blocked material. In this embodiment, the cam 31 is coaxially connected to the first gear 311, and the rotating shaft of the cam 31 can be rotatably mounted on a bracket fixed on the outer wall of the cylinder 1 to keep the position of the cam 31 stable. The rotating driver 32 of the driving unit 3 is the driving source. When the rotating driver 32 is connected to the first gear 311 in transmission, the cam 31 can be driven to rotate. The rotating driver 32 can be a servo motor.

[0024] In order to solve the problem of how to improve the stability of the movement of the discharge pipe 132, the following features are specifically set: An inner bottom plate 135 surrounding the inner wall of the discharge pipe 13 is arranged at the bottom of the discharge pipe 13, and the inner wall of the inner bottom plate 135 fits the outer wall of the discharge pipe 132; a guide rod 43 extending vertically downward is arranged on the connecting rod 41 of the movable sleeve 4, and the guide rod 43 is inserted on the inner bottom plate 135. A spring 431 is sleeved on the guide rod 43, and the spring 431 elastically connects the movable sleeve 4 and the inner bottom plate 135, and the spring 431 applies elastic force to move the movable sleeve 4 downward.

[0025] In this embodiment, the guide rod 43 arranged on the connecting rod 41 is inserted into the inner bottom plate 135 of the inner wall of the discharge pipe 13 to improve the stability of the movement of the discharge pipe 132. The spring 431 sleeved on the guide rod 43 provides elastic force for the guide rod 43 to move downward, thereby ensuring that the side strip 42 always keeps in contact with the side wall of the cam 31 when the cam 31 rotates. The connecting rod 41 can also be set at the bottom of the discharge pipe 132.

[0027] In this embodiment, the stirring frame 2 is sleeved in the ring sleeve 14 at the top of the mixing chamber 11 through the limiting ring 23 at the top to stabilize the axis of the stirring frame 2. A tooth groove 231 is arranged on the upper side of the limiting ring 23. The second gear 33 of the driving unit 3 is meshed and connected with the top of the limiting ring 23 through the notch 15 at the top of the cylinder 1. When the second gear 33 rotates, the stirring frame 2 can be driven to rotate in the mixing chamber 11 to stir and mix the materials in the mixing chamber 11. The limiting ring 23 always blocks the notch 15, which will not cause leakage of the materials in the mixing chamber 11. The second gear 33 can be rotatably installed on the bracket arranged on the outer wall of the cylinder 1 to keep the axis stable. The third gear 331 is coaxially connected with the second gear 33. When the rotating driver 32 is connected to the third gear 331, the second gear 33 and the stirring frame 2 can be driven to rotate.

The axis of the driven gear 322 is in the same straight line as the first friction disk 345. The upper and lower sides of the driven gear 322 are coaxially provided with second friction disks 324.

The upper and lower sides of the driven gear 322 are provided with a second friction disk 324. When the movable bracket 35 moves up, the second friction disk 324 contacts the first friction disk 345 on the upper side of the fixed bracket 34 and drives the first friction disk 345 and the second bevel gear 344 to rotate. The rotation of the second bevel gear 344 drives the first bevel gear 343 to rotate, and the first bevel gear 343 drives the fourth gear 342 to rotate. The fourth gear 342 drives the third gear 331 to rotate synchronously through the first synchronous belt 341, thereby realizing the synchronous rotation of the second gear 33 and the stirring frame 2. The stirring frame 2 stirs the material in the mixing chamber 11. At this time, the movable sleeve 4 and the discharge pipe 132 lose the power source and cannot vibrate.

When the movable bracket 35 moves downward, the shaft rod 351 moves downward in the shaft sleeve 122, and the bottom end of the shaft rod 351 moves downward to contact the horizontal inner convex strip 127 set at the top of the extension paddle 124. The shaft rod 351 presses the inner convex strip 127 to make the extension paddle 124 rotate around the top hinge axis, and the bottom of the extension paddle 124 turns outward and unfolds. When moving upward, the top block 355 at the bottom of the shaft 351 is connected to the shaft 351 through the thin rod 354 so that it can move synchronously with the shaft 351. The top block 355 moves up to the top end and fits under the inner convex strip 127, thereby driving the extended paddle 124 to reset until the extended paddle 124 is in a vertical state, the inner wall of the extended paddle 124 fits around the top block 355, and the bottom of the inner convex strip 127 fits the top of the top block 355. The up and down movement of the shaft 351 can drive the extended paddle 124 to expand or contract accordingly, reducing manual intervention and saving costs.

[0035] Working principle: When in use, the staff adds raw materials into the mixing chamber 11 of the cylinder 1 through the feed pipe 12. At this time, the feed pipe 13 at the bottom of the cylinder 1 is blocked by the lower blocking cover 131. During processing, the upper blocking cover 121 blocks the feed pipe 12, and the driving unit 3 starts to drive the stirring frame 2 to rotate and mix and stir the raw materials in the mixing chamber 11 to fully dissolve them. After the processing is completed, the lower blocking cover 131 is removed to open the feed pipe 13, and the mixed special medical food is discharged from the feed pipe 1 at the bottom of the mixing chamber 11. The material is discharged from between the discharge pipe 132 and the sleeve 122 at 3. When the special medical food inside is blocked during discharge, the discharge pipe 132 can reciprocate along the axial direction in the discharge pipe 13 to vibrate the material, thereby discharging the blocked material. At the same time, the extended paddle 124 hinged at the strip through hole 123 at the bottom of the sleeve 122 flips outward around the hinge axis and protrudes from the surface of the sleeve 122, thereby shifting the material when the discharge pipe 132 reciprocates and vibrates up and down, thereby clearing the blocked material.
