Description

Technical Field

[0001] The utility model relates to the technical field of microcapsule manufacturing, in particular to a microcapsule flow solidification collection device. Background Art

[0002] Microcapsules are widely used in industries such as food, medicine, and cosmetics. The preparation of existing relatively large-sized microcapsules mostly adopts the dropping method, and usually an inner tube and an outer tube are sleeved to form a microchannel dropping tube. Some devices for preparing microcapsules by multi-channel amplification adopt dropping tubes distributed on both sides or circularly, and the microcapsules are solidified in the tank by the way of jetting through the dropping tubes into the solidifying liquid tank. For microcapsules with sodium alginate as the outer material, the existing technology has appeared using calcium chloride solution as the solidifying liquid and recycling it. Especially in the multi-channel batch preparation of microcapsules, the generation of a large number of microcapsules causes the tank to be filled with microcapsules, and the microcapsules generated by continuous dropping will collide with the microcapsules floating on the liquid surface, resulting in the failure of the subsequent generation of microcapsules by dripping. Summary of the Utility Model

[0003] In order to solve the problem in the existing technology that the generation of a large number of microcapsules causes the tank to be filled with microcapsules, and the microcapsules generated by continuous dropping will collide with the microcapsules floating on the liquid surface, resulting in the failure of the subsequent generation of microcapsules by dripping, the utility model provides a microcapsule flow solidification collection device.

[0004] A microcapsule flow solidification collection device includes a circulation pump, a multi-way diverter, a flow collection tank, a filter tank, and a solidifying liquid tank that are connected in sequence to form a solidifying liquid circulation line; the multi-way diverter has at least four outlet pipes arranged in a row, the flow collection tank has a liquid storage pool, a slope, and a rectangular channel, the outlet pipes of the multi-way diverter are installed on the side wall of the liquid storage pool, the higher side of the slope is connected to the side wall of the liquid storage pool opposite to the outlet pipes, and the lower side of the slope is connected to the rectangular channel; both the filter tank and the solidifying liquid tank are located below the rectangular channel, and the filter tank is placed in the solidifying liquid tank.

[0005] Optionally, the multi-way diverter is an eight-way diverter, the eight-way diverter has an eight-way diverter inlet pipe and eight eight-way diverter outlet pipes, and the eight-way diverter inlet pipe is communicated with the eight eight-way diverter outlet pipes.

[0006] Optionally, the side wall of the liquid storage pool has eight flow tank inlet holes, and the eight eight-way diverter outlet pipes are inserted into the eight flow tank inlet holes so that the eight-way diverter is fixedly installed on the flow collection tank.

[0007] Optionally, a circular tooth-shaped notch is installed on the side wall of the liquid storage pool opposite to the outlet pipes, and the circular tooth-shaped notch has a number of semi-circular grooves.

[0008] Optionally, the slope is closed, which means that one end of the slope is larger than the other end. More specifically, the end where the microcapsules enter the slope is larger, so that the microcapsules can enter the slope more easily, while the end where the microcapsules flow out is smaller, so that the microcapsules can be collected more easily. The large and small are the relative sizes of the two ends of the slope. Optionally, the slope bottom plate has an inclination angle of 100° relative to the side wall of the liquid storage tank when viewed from the side, forming a downward slope.

[0009] Optionally, the rectangular channel is arranged at the closing end of the slope.

[0010] Optionally, the rectangular channel is a vertical channel.

[0011] Optionally, the microcapsule flow solidification collection device includes a support plate, and the support plate mainly supports the bottom plate of the slope.

[0012] Optionally, the coagulation liquid tank is connected to the circulation pump via a connecting pipeline, and the eight-way diverter is connected to the circulation pump via a connecting pipeline.

[0013] Optionally, the circulation pump is any one of a turbine pump, a peristaltic pump, and a centrifugal pump.

[0014] The utility model proposes a microcapsule flow solidification collection device. Compared with the flat notch, the round toothed notch has the effect of the protruding teeth on the surface tension of the liquid, so that the microcapsules floating on the water surface are higher than the lowest point of the circular groove, which helps the microcapsules to flow over the notch. In the flat groove, the microcapsules are lower than the groove surface, making it difficult for the microcapsules to flow over the notch. The slope adopts a closed setting, combined with a rectangular channel, to better complete the focused collection. At the same time, the solidification liquid that circulates in the device avoids the collision and rupture of the microcapsules in the collection tank when the microcapsules drip and collide with the solidified microcapsules, thereby achieving smooth preliminary collection of the microcapsules.

[0023] Embodiment

[0024] As Figure 1 shown, a microcapsule flow solidification collection device proposed by the present utility model includes a circulation pump 1, an eight-way diverter 2, a flow collection trough 3, a filter trough 4, a solidifying liquid trough 5, a connecting pipeline 6, etc

[0025] The circulation pump 1 is a turbine pump, which has a circulation pump inlet 101 and a circulation pump outlet 102. The circulation pump can pump liquid, take in liquid from the circulation pump inlet 101 and discharge liquid from the circulation pump outlet 102, providing the power for the circulation of the solidifying liquid

[0026] The eight-way diverter 2 includes an eight-way diverter inlet pipe 201 and eight eight-way diverter outlet pipes 202. All the eight-way diverter outlet pipes 202 are arranged in a row and are communicated with the eight-way diverter inlet pipe 201. Optionally, the eight eight-way diverter outlet pipes 202 have the same size, and the inner diameter of the pipes is smaller than the inner diameter of the eight-way diverter inlet pipe 201, so that the solidifying liquid enters the pipe from an eight-way diverter inlet pipe 201 and uniformly forms a split jet in the eight eight-way diverter outlet pipes 202, timely washing away the microcapsules floating on the liquid surface in the liquid storage pool and ensuring the downstream flow of the microcapsules

[0027] The flow collection trough 3 includes eight flow trough inlet holes 301, a liquid storage pool 302, a serrated notch 303, a slope 304, a rectangular channel 305, and a support plate 306. The eight flow trough inlet holes 301 are arranged in a row on a side wall of the flow collection trough 3, and the eight eight-way diverter outlet pipes 202 are inserted into the eight flow trough inlet holes 301, so that the eight-way diverter 2 is fixedly installed on the flow collection trough 3. The liquid storage pool 302 is located at the top of the flow collection trough 3. Taking the side wall where the eight flow trough inlet holes 301 are located as the upstream of the flow collection trough 3, and the side opposite to the eight flow trough inlet holes 301 is the downstream of the flow collection trough 3. A serrated notch 303 is installed on the downstream side wall of the liquid storage pool 302, as Figure 2As shown, the circular-tooth-shaped notch 303 has several semi-circular grooves with the semi-circular arcs facing downward. The diameter of the semi-circular grooves is larger than the diameter of the prepared microcapsules 7, facilitating the flow of the microcapsules to the downstream of the flow collection tank 3. The liquid storage tank 302 temporarily stores the solidifying liquid 8 ejected from the eight-way diverter 2, ensuring that the dropped microcapsules can be preliminarily cross-linked and solidified in the liquid storage tank. A slope 304 is installed on the downstream side of the circular-tooth-shaped notch 303. The slope 304 is composed of a bottom plate and a side plate, and is set with a narrowed opening. The inclination angle is 100°. The inclination angle refers to the inclination angle of the bottom plate of the slope 304 relative to the side wall of the liquid storage tank 302. The rectangular channel 305 is arranged in cooperation with the narrowed end of the slope 304 (the downstream end of the slope 304) to better complete the focusing and collection. When the microcapsules cross the circular-tooth-shaped notch 303, they slide from the slope 304 to the rectangular channel 305. The rectangular channel 305 is a vertical channel, which can make the microcapsules fall into the filter tank 4 located below the rectangular channel 305. The support plate 306 mainly supports the bottom plate of the slope 304, strengthens the fixation of the slope 304, improves the stress capacity of the suspended slope 304, extends the service life of the flow collection tank 3, and prevents the sealant at the interface from disconnecting and separating.

[0028] The filter tank 4 is an acrylic tank with a filter screen at the bottom. The aperture of the filter screen is selected according to the size of the microcapsules, and the filter screen is fixedly installed at the bottom of the filter tank 4 by stainless steel screws and nuts. The filter tank 4 is placed in the solidifying liquid tank 5 and can be taken out manually or mechanically.

[0029] The solidifying liquid tank 5 is provided with a liquid outlet pipe orifice 501 of the solidifying liquid tank, which is connected to the inlet 101 of the circulation pump by a silica gel tube. The connecting pipeline 6 can adopt a silica gel tube. The inlet pipe 201 of the eight-way diverter is connected to the outlet 102 of the circulation pump by a silica gel tube, and the outlet pipe 202 of the eight-way diverter is communicated with the flow collection tank 3; the eight outlet pipes 202 of the eight-way diverter are fixedly installed in the eight flow tank inlet holes 301 of the flow collection tank 3 by hot melt adhesive. The circular-tooth-shaped notch 303 in the flow collection tank 3 is semi-circular teeth, which can ensure that the microcapsules cross the notch and flow out.

[0030] When the microcapsule flow coagulation collection device is used in the production and preparation of microcapsules, the microcapsules are dropped in batches from above the liquid storage pool 302 of the flow collection tank into the liquid storage pool 302. The coagulation liquid tank 5 is filled with a calcium chloride solution with a mass fraction of 5% as the coagulation liquid. The circulation pump 1 is started, and the flow rate is set to 100 mL / min, and the coagulation liquid is circulated in the "coagulation liquid tank - eight-way diverter - flow collection tank - filter tank". The circulation pump 1 extracts the coagulation liquid from the coagulation liquid tank 5. The coagulation liquid comes out from the liquid outlet pipe orifice 501 of the coagulation liquid tank, flows into the inlet 101 of the circulation pump through the connecting pipeline 6, and then is transported to the inlet pipe 201 of the eight-way diverter through the connecting pipeline 6 from the outlet 102 of the circulation pump. Then, through eight eight-way diverter outlet pipes 202, eight jets of coagulation liquid are sprayed into the liquid storage pool 302 of the flow collection tank 3 to push the microcapsules that are dropped in the liquid storage pool 302 and float on the liquid surface forward. Due to the power provided by the jet, the microcapsules run out from the round-tooth-shaped notch 303 and further slide down to the rectangular channel 305 through the slope 304 of the flow collection tank 3; then, they further fall into the filter tank 4 through the vertical rectangular channel 305 and are collected, and further cross-linking and curing are completed therein. The filter tank 4 is fished out to obtain the filtered and collected microcapsules.
