Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of temperature control material passageways. BACKGROUND

[0002] During the process of material conveying through pipeline, sometimes material needs to be kept at a certain temperature, and the passageway through which the material passes needs to be heat-exchanged to some extent to avoid the temperature of the material rising or falling, for example:

[0003] In the field of biological medicine and chemistry, many instruments generate heat during operation, and some of the heat is directly transmitted to the internal material, affecting the state of the material, such as pulverizers, high-pressure homogenizers, fermentation tanks, centrifuges, etc. The high-pressure homogenizer used for crushing in the field of biological medicine and food is mostly a plunger pump type. The production of pharmaceutical emulsions must use an ultrahigh-pressure homogenizer (with a pressure of at least 20,000 psi). Under the action of high pressure, the material is conveyed to an adjustable homogenizing valve under the reciprocating action of the plunger, and is subjected to strong compression. When passing through the flow-limiting slit, it hits the homogenizing valve at a very fast speed, generating cavitation effect, impact effect, and shear effect, which uniformly disperses the agglomerated material.

[0004] Due to the extremely high pressure of the material in the valve seat passageway, a large amount of heat is released when it hits and rubs against the homogenizing valve, causing the temperature of the material to rise rapidly after impact and crushing. For heat-sensitive materials, when the temperature exceeds the denaturation temperature or the inactivation temperature, it will denature or inactivate rapidly. In order to ensure that the material still has specific biological and chemical properties after crushing, or that the extracted substance has sufficient activity, it is necessary to avoid rapid temperature rise.

[0005] Sometimes, the material passing through needs to be kept at a certain high temperature, in which case the material passageway needs to be heated. For example, when a mixer is used to mix and dissolve different physical state (solid, liquid) materials, certain heating conditions are usually required to promote rapid dissolution and mixing of the materials.

[0006] Currently, there are few material handling devices that can effectively control the temperature under certain conditions. Inadequately designed handling devices often fail to achieve the desired temperature control effect.

[0007] The present application adopts a new temperature control material passageway to maximize the temperature control effect in the device and prevent adverse effects caused by the inability to maintain the temperature within a certain range when the material passes through. SUMMARY

[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0046] As shown in the accompanying drawings of the specification, Figures 1-4 For the convenience of description, different axial directions are marked in the drawings. The X-axis direction refers to the left-right direction in the horizontal direction, and the positive direction is defined from left to right. The corresponding Y-axis direction refers to the front-back direction in the horizontal plane, and the positive direction is defined from back to front. The Z-axis refers to the direction perpendicular to the horizontal plane, and the positive direction is defined from bottom to top.

[0047] The present embodiment provides a temperature-controlled material channel, which comprises:

[0048] a first material channel cavity (3) for allowing external materials to enter and pass through; and

[0049] at least one temperature control channel corresponding to the material channel cavity, for passing a heat exchange medium to exchange heat with the material channel cavity,

[0050] wherein the temperature control channel is arranged close to the first material channel cavity (3) with a curved cross section, and the entire curved cross section extends along the extension direction of the first material channel cavity (3).

[0051] As shown in the example in FIG. (2), the cross section of the temperature control channel in the Z-axis direction is a curved surface, and the bottom of the curved surface is close to the first material channel cavity (3).

[0052] The heat exchange medium in the present embodiment can be selected according to the need to heat or cool the material to improve the heat or refrigeration.

[0053] The temperature control material passage can be an independent device component, which can be installed in a material processing equipment (such as an emulsifier, a high-pressure homogenizer, etc.) of a corresponding model and size, and can provide cold or heat for the material passage cavity inside the material processing equipment by providing a flowing heat exchange medium such as a cooling liquid or a heat medium, so as to achieve the effect of cooling or heating. The cavity for flowing of the heat exchange medium is a temperature control cavity. The temperature control cavity is in close contact with one side of the first material passage cavity (3) and can cover the entire length of the first material passage cavity (3) as much as possible, so as to ensure a sufficient heat exchange area. Therefore, the temperature control cavity approaches the first material passage cavity (3) in a curved surface section, and the section extends along the extension direction of the first material passage cavity (3) and remains consistent in the length direction. The temperature control cavity and the first material passage cavity exchange heat through a wall that respectively contacts the interval between them, so that the heat exchange medium can conduct heat (cold) to the material passage cavity, thereby achieving heat exchange. In order to better achieve heat exchange, in this case:

[0054] In one case, the temperature control cavity and the first material passage cavity are both grooves formed by boring the temperature control material passage, and the entire temperature control material passage is made of a heat-conducting material (for example, 316L). Heat conduction and heat exchange are performed through the wall between the temperature control cavity and the first material passage cavity, that is, the interval between the two grooves.

[0055] In another case, the temperature control cavity and the first material passage cavity can also be pipes respectively bored in the temperature control material passage, and heat conduction and heat exchange are performed by respectively contacting the two pipes through a wall that is spaced between the two pipes. In this case, the pipes and the wall that respectively contacts and spaces can be made of a heat-conducting material, for example, 316L.

[0056] The curved surface can be designed in any shape according to requirements, and is preferably in a U shape. The heat exchange medium flows into the temperature control cavity from a heat exchange medium inlet, exchanges heat with the material passage cavity during the flow in the temperature control cavity, and finally flows out from a heat exchange medium outlet.

[0057] In addition, the curved surface can also cause the heat exchange medium to generate vortex flow during the flow through the section, so that the heat exchange medium can be better mixed, the heat exchange speed and efficiency are improved, and the heat exchange effect is improved.

[0058] In an example, the temperature control cavity has two (6, 7), and the two temperature control cavities are connected and symmetrically arranged on two sides of the first material passage cavity (3) to approach the first material passage cavity from two symmetric sides of the first material passage cavity.

[0059] In an example, the projection of the temperature control cavity on the first material passage cavity (3) can cover the first material passage cavity as much as possible, that is, the length and width of the temperature control cavity can cover the first material passage cavity as much as possible, so as to improve the heat exchange effect as much as possible.

[0060] According to the shape and structure of the material passage to be controlled in temperature, the temperature control cavity can be arranged in multiple numbers around the material passage cavity, for example, two temperature control cavities symmetrically arranged on both sides of the first material passage cavity (3) and communicated with each other; or in other arbitrary numbers to ensure that the projection of the temperature control cavity on the first material passage cavity (3) can cover the first material passage cavity (3) as much as possible.

[0061] In a preferred example, the heat exchange medium enters from one of the temperature control cavities and is discharged from another of the temperature control cavities. The heat exchange medium flows in the temperature control cavity, and when the two temperature control cavities are communicated, the inlet and outlet of the heat exchange medium can be arranged on each temperature control cavity respectively; or the heat exchange medium can enter from one of the temperature control cavities and be discharged from another of the temperature control cavities. Considering the manufacturing difficulty of the device, the heat exchange demand and the operation difficulty, the latter way is preferred, that is, the heat exchange medium enters from one temperature control cavity, continuously flows through the two communicated temperature control cavities, and then flows out from the end of the latter temperature control cavity, so as to better control the flow speed of the heat exchange medium and ensure that there is no dead angle in the temperature control cavity.

[0062] According to the processing demand of the material, the material passage cavity can be arranged in two or more numbers and communicated with each other, so as to ensure that the material can be continuously processed and discharged from the device in time for collection or storage. In an example, the temperature-controlled material passage further comprises:

[0063] a second material passage cavity (5) through which the material passes,

[0064] the second material passage cavity (5) is communicated with the first material passage cavity (3),

[0065] Preferably, the material enters from the first material passage cavity (3) and flows out from the second material passage cavity (5), that is, one end of the second material passage cavity (5) is connected with one end of the first material passage cavity (3), and the other end can be connected with a discharge pipeline or a material collecting component, so as to convey the processed material out.

[0066] In an example, the two temperature control cavities are symmetrically arranged and communicated through at least one vertical channel (8) vertically arranged at both ends of the two temperature control cavities, and the vertical channel is as close as possible to the second material passage cavity (5), so that the vertical channel can effectively exchange heat with the second material passage cavity (5).

[0067] Likewise, the vertical channels and the second material passage cavities are grooves formed in the heat-conducting temperature-controlled material passage, or are heat-conducting pipes formed in the heat-conducting temperature-controlled material passage, and the heat exchange is conducted by the contact heat conduction between the walls separating the grooves or the pipes.

[0068] The vertical channels (8) are mainly used to connect the two temperature-controlled cavities, so that the heat exchange medium can surround the entire second material passage cavity (5) as much as possible. Therefore, the "vertical" does not necessarily mean the vertical relative to the horizontal position, but means the vertical relative to the positions of the two temperature-controlled cavities, that is, the vertical relative to the main flow direction of the heat exchange medium in the two temperature-controlled cavities.

[0069] When there are multiple vertical channels (8), they can be arranged around the second material passage cavity (5) to increase the heat exchange effect.

[0070] In an example, the vertical channels (8) are two, and the two vertical channels are symmetrically distributed on the two sides of the second passage cavity (5).

[0071] In an example, the inlet (heat exchange medium inlet) for the heat exchange medium arranged in one temperature-controlled cavity (6) is symmetrically arranged with the outlet (heat exchange medium outlet) for the heat exchange medium arranged in the other temperature-controlled cavity (7), that is, both are opened at the same corresponding position, and the other ends of the corresponding positions of the two temperature-controlled cavities extend to the second material passage (5) and are connected by the vertical channels (8).

[0072] Preferably, the cross section of the vertical channel (8) is in the shape of a waist (9) extending along the extension direction of the second material passage cavity (5), so as to increase the area of the second material passage cavity covered by the vertical channel and provide the heat exchange efficiency.

[0073] In order to better exchange heat for the pipe parts at different positions of the material passage cavity, two parallel vertical channel pipes can be arranged, which are symmetrically distributed on the two sides of the second material passage cavity (5), that is, the second material passage cavity (5) is sandwiched therebetween.

[0074] In an example, the extension direction of the first material passage cavity (3) is perpendicular to the extension direction of the second material passage cavity (5). The first material passage cavity (3) is mainly used for inputting and processing the material, and the second material cavity (5) is used for guiding the processed material out of the device. Therefore, the positional relationship of the two is mainly designed according to the processing requirements of the material. A typical relationship is that the first material passage cavity (3) extends in the Z-axis or Y-axis direction, and the second material cavity (5) extends in the X-axis direction, or it can be simply considered that the two are in a relatively perpendicular relationship.

[0075] Preferably, the temperature control cavity is arranged close to the outer wall of the temperature control material channel, for example Figure 2 As shown in FIG. 6, two temperature control cavities are arranged close to the upper and lower outer walls of the temperature control material channel respectively.

[0076] According to different requirements, the temperature control cavities (6, 7) and / or the vertical channel (8) can be arranged at different positions, especially the positional relationship with the first material channel cavity (3), which can be adjusted according to the material type, temperature control requirements, etc. For example, the temperature control cavities and / or the vertical channel (8) can be arranged in the temperature control material channel, or directly formed by grooving in the temperature control material channel, so that the temperature control cavities become an internal sleeve similar to the first material channel cavity (3) and directly contact the material in the first material channel cavity (3) to achieve more efficient heat exchange.

[0077] In a preferred example, the heat exchange medium is cooling liquid or heat medium, preferably water. As the most commonly used cooling medium or heating medium, water is inexpensive and can meet the cooling or heating requirements in most cases. Of course, the cooling liquid can also choose other commonly used media as long as it can meet the cooling requirements.

[0078] In a preferred example, the first material channel cavity (3) is provided with components for processing materials, such as impact components, crushing blades, etc. The first material channel cavity (3) is the main heat generating part, i.e. the main part for material processing, so it can be provided with related components for material processing according to the requirements of the equipment to realize the main function of the material processing equipment.

[0079] In an example, the temperature control material channel is further provided with a control system, which includes temperature sensors, flow sensors, etc. The temperature sensors measure the temperature in the first material channel cavity (3) and / or the second material channel cavity (5) at any time, so as to detect the temperature of the material in real time, and adjust the flow speed of the heat exchange medium in the temperature control cavity by controlling the flow of the heat exchange medium, so as to adjust the speed of heat exchange and realize the temperature control of the material.

[0080] In an example, the temperature control material channel is spliced or assembled, and the splicing part of each part is sealed by a sealing ring or sealing glue to ensure the sealing of the whole and prevent the heat exchange medium from leaking to other places of the material processing equipment.

[0081] In another example, the temperature control material channel is integrally formed, such as integrally formed by using 3D printing technology, which ensures good sealing of the structure and does not need to be sealed additionally.

Alternatively, it can be distinguished from the coordinate axis direction, the first material channel is located in the Y or Z axis direction, and the second material channel is located in the X axis direction.

[0086] The first material channel cavity (3) is used for introducing and homogenizing the material, the second material channel cavity (5) is used for outputting the processed material, and the temperature-controlled cavity is used for reducing the temperature of the materials in the two material channels, thereby preventing the loss of heat-sensitive substances.

[0088] The vertical channel (8) is a connecting pipeline that is parallel and side by side, and the two ends are connected but the middle is not connected. The middle sections of the two vertical channels are respectively distributed on both sides of the material processing equipment discharge channel; the front view of any one end of the vertical channel is two parallel oval ring holes, or waist-shaped holes (9).

[0089] The temperature-controlled cavity further comprises a heat exchange medium inlet (1) and an outlet (2), which are respectively located at the ends of the first and second temperature-controlled cavities close to the equipment shell (4).

[0090] The first material channel (3) is provided with other high-pressure homogenizing components for realizing homogenization.

[0091] The longitudinal section of the curved surface of the first temperature control cavity (6) or the second temperature control cavity (7) is close to U-shaped, so that the heat exchange medium can be close to the material processing part to the greatest extent, and the heat exchange medium can quickly realize heat exchange when entering the cavity.

[0092] In use of the embodiment, the material is passed into the material channel for homogenization treatment, the flow rate and flow of the heat exchange medium, i.e. the cooling liquid, are adjusted according to the cooling requirement of the material in the high-pressure homogenizer, the cooling liquid is passed into the first temperature control cavity from the heat exchange medium inlet, the cooling liquid generates vortex flow to quickly perform heat exchange, and the cooling liquid continues to flow through the vertical channel to flow into the second temperature control cavity, so that the material channel is comprehensively cooled or heated at each position, and finally the cooling liquid flows out from the cooling liquid outlet and is recycled after heat exchange.
