Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection structures, in particular to a microchannel reactor. Background Art

[0002] A microchannel reactor refers to a miniature reactor with a characteristic size between 10 and 300 microns (or 1000 microns) manufactured using precision machining technology. The microchannel reactor has excellent heat and mass transfer capabilities and can achieve instantaneous uniform mixing of materials and efficient heat transfer.

[0003] At present, the material inlet and outlet of a microchannel reactor are usually connected to a hose, and the hose and the material inlet and outlet are locked by a pressure ring. This locking method can easily cause the hose to deform seriously, and even reduce the inner diameter of the hose by more than 1 / 3, which will seriously affect the material transmission effect; in addition, the existing joints that realize the connection between the material inlet and outlet and the hose also have problems such as low pressure resistance and easy leakage, which affects the normal use of the microchannel reactor.

[0004] Therefore, it is an urgent problem to be solved at this stage to develop and design a microchannel reactor that can stably connect the hose with the material inlet and outlet of the microchannel reactor, in which the hose will not be seriously deformed and is not easy to fall off and leak.

[0005] In order to solve the problems existing in the prior art, the utility model provides a microchannel reactor, in which a pressure ring is sleeved on a hose, and first conical surfaces at both ends of the pressure ring extend into a hollow screw and an inner core of a joint respectively. When the hollow screw is tightened, the extrusion force applied by the hollow screw to the first conical surface can effectively promote the two ends of the pressure ring to produce radial inward deformation, so that the inner wall surface of the pressure ring fits tightly with the hose; at the same time, a plurality of split grooves arranged at the end of the pressure ring can further improve the deformation effect of the pressure ring, and can firmly clamp the hose to ensure that the hose is stably connected with the inner core of the joint, and has higher pressure resistance and temperature resistance. The hose will not be seriously deformed and is not easy to fall off or leak.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The utility model provides a microchannel reactor, comprising:

[0008] A reactor body, wherein the reactor body has a microchannel inside, and the reactor body is provided with a joint inner core connected to the microchannel; the joint inner core is sleeved with a connecting nut outside, and the connecting nut is fixedly connected to the reactor body;

[0009] A hollow screw, wherein the hollow screw is threadedly connected to the connecting nut;

[0010] A hose, the hose passes through the hollow screw and extends into the inner core of the joint;

[0011] A pressure ring is sleeved on the hose and is located between the hollow screw and the connector inner core; outer wall surfaces at both ends of the pressure ring are set as first conical surfaces, and both ends of the pressure ring extend into the hollow screw and the connector inner core respectively; a plurality of split grooves are provided at one end of the pressure ring facing the hollow screw.

[0012] As a preferred technical solution, the hollow screw and the joint inner core are both provided with a second conical surface matching the first conical surface.

[0013] As a preferred technical solution, the joint inner core, the connecting nut, the hollow screw, the hose and the pressure ring are all coaxially arranged.

[0014] As a preferred technical solution, the plurality of split grooves are evenly distributed along the circumference of the axis of the pressure ring;

[0015] And / or, the number of the split grooves is set to four.

[0016] As a preferred technical solution, the split groove connects the inner wall surface and the outer wall surface of the pressure ring;

[0017] And / or, along the axial direction of the pressure ring, the depth of the split groove is greater than the length of the first conical surface.

[0018] As a preferred technical solution, the pressure ring is provided with a shoulder that matches the end face of the hollow screw and / or the inner core of the joint.

[0019] As a preferred technical solution, the pressure ring is configured as an integrated structure or a split structure.

[0020] As a preferred technical solution, a positioning surface matching the end surface of the hose is provided in the inner core of the joint.

[0021] As a preferred technical solution, the reactor body comprises a mounting plate, the mounting plate is provided with a connecting hole, the joint inner core is located in the connecting hole, and the connecting nut is fixedly connected to the connecting hole.

[0022] As a preferred technical solution, the connecting nut has an external thread, the connecting hole has an internal thread, and the connecting nut is threadedly connected to the connecting hole.

[0023] The beneficial effects of the utility model are as follows:

[0024] 1. The compression ring of the utility model is sleeved on the hose, and the first conical surfaces at the two ends of the compression ring extend into the hollow screw and the inner core of the joint respectively. When the hollow screw is tightened, the extrusion force applied by the hollow screw to the first conical surface can effectively promote the two ends of the compression ring to produce radial inward deformation, so that the inner wall surface of the compression ring and the hose are closely fitted; a plurality of split grooves arranged at the end of the compression ring can further improve the deformation effect of the compression ring, and can firmly clamp the hose to ensure that the hose is stably connected with the inner core of the joint, and has higher pressure resistance and temperature resistance. The hose will not be seriously deformed, and is not easy to fall off and leak.

[0025] 2. The compression ring of the utility model is provided with a shoulder that matches the end face of the hollow screw and the inner core of the joint. When the shoulder abuts against the end face of the hollow screw or the inner core of the joint, the relative positions of the compression ring, the hollow screw and the inner core of the joint can be limited, thereby preventing the compression ring from extending too far into the hollow screw or the inner core of the joint, and avoiding excessive deformation of the end of the compression ring, which causes the inner diameter of the hose to be reduced too much.

[0026] 3. The connection nut and the joint core of the utility model are separately arranged. At the same time, the connection nut can be conveniently fixed on the reactor body, which is convenient for installation, disassembly and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.

[0033] Embodiment 1

[0034] Please refer to Figure 1-Figure 3, is an embodiment of a microchannel reactor provided by the utility model, comprising a reactor body, the reactor body having a microchannel inside, a joint core 2 connected to the microchannel is provided on the reactor body, a hose 5 extends into the joint core 2, and materials can enter and exit the microchannel inside the reactor body through the hose 5 and the joint core 2; a connecting nut 3 is sleeved on the outside of the joint core 2 and fixedly connected to the reactor body, a hollow screw 4 is threadedly connected to the connecting nut 3, the hose 5 passes through the hollow screw 4, a pressure ring 6 is sleeved on the hose 5 and is located between the hollow screw 4 and the joint core 2, the two ends of the pressure ring 6 are respectively extended into the hollow screw 4 and the joint core 2, and the pressure ring 6 The outer wall surfaces at both ends are set as the first conical surface 61. When tightening the hollow screw 4, the extrusion force exerted by the hollow screw 4 on the first conical surface 61 can effectively promote the radial inward deformation of the two ends of the pressure ring 6, so that the inner wall surface of the pressure ring 6 is tightly fitted with the hose 5; a plurality of split grooves 62 are provided at the end of the pressure ring 6 extending into the hollow screw 4, and the split grooves 62 can further improve the deformation effect of the pressure ring 6 at the first conical surface 61, increase the contact area between the inner wall surface of the pressure ring 6 and the hose 5, and can firmly clamp the hose 5. At the same time, the end of the pressure ring 6 extending into the connector core 2 is sealed under the action of the first conical surface 61, ensuring that the hose 5 is stably connected to the connector core 2.

[0035] For further information, please refer to Figure 2 , the hollow screw 4 and the joint inner core 2 should be provided with a second conical surface 41 matching the first conical surface 61. When the second conical surface 41 is tightly fitted with the first conical surface 61, it can not only ensure the sealing effect, but also guide the stable radial contraction of the pressure ring 6 to ensure the clamping effect of the hose 5; specifically, the diameter of the first conical surface 61 gradually increases in the direction approaching the middle of the pressure ring 6, and the inclination angle of the second conical surface 41 is consistent with the first conical surface 61, which can ensure the sealing while enabling the pressure ring 6 to have the best radial contraction effect.

[0036] For clarification, please refer to Figure 1 and Figure 2 The joint core 2, connecting nut 3, hollow screw 4, hose 5 and pressure ring 6 should be coaxially arranged. When the hollow screw 4 is tightened onto the connecting nut 3, the pressure ring 6 can be effectively promoted to cooperate with the joint core 2 and the hollow screw 4 respectively, to ensure a stable sealing and positioning of the hose 5.

[0037] In this embodiment, please refer to Figure 1 and Figure 3 The number of the split grooves 62 is set to four, and the four split grooves 62 are evenly distributed along the circumference of the axis of the pressure ring 6 to form a cross opening, which can improve the deformation effect of the end of the pressure ring 6, and thus can more firmly position the hose 5; in other embodiments, the number of the split grooves 62 can also be other values, so as to ensure the stable deformation of the end of the pressure ring 6.

[0038] For clarification, please refer to Figure 1 and Figure 3 The split groove 62 preferably connects the inner wall surface and the outer wall surface of the pressure ring 6, which can ensure that the end of the pressure ring 6 is easier to deform; further, along the axial direction of the pressure ring 6, the depth of the split groove 62 should be greater than the length of the first conical surface 61, which can further increase the deformation amount of the first conical surface 61 of the pressure ring 6 when it is squeezed.

[0039] In this embodiment, please refer to Figure 2 The hose 5 is preferably matched with the hollow screw 4 and the joint core 2 respectively, to ensure that the hose 5 can smoothly pass through the hollow screw 4 and extend into the joint core 2, avoiding the appearance of a large gap; further, a positioning surface 21 matching the end face of the hose 5 should be provided in the joint core 2, and when the positioning surface 21 abuts against the end face of the hose 5, the position of the hose 5 can be located.

[0040] For clarification, please refer to Figure 1-Figure 3 The pressure ring 6 is set as an integrated structure to facilitate production and installation.

[0041] In this embodiment, please refer to Figure 1 and Figure 2 The reactor body includes a mounting plate 1, a connecting hole 11 is provided on the mounting plate 1, a joint core 2 is located in the connecting hole 11, and a connecting nut 3 is fixedly connected to the connecting hole 11, so that the hose 5 and the joint core 2 can be conveniently and stably connected. Specifically, the connecting nut 3 has an external thread, and the connecting hole 11 has an internal thread. The connecting nut 3 and the connecting hole 11 are fixed to the reactor body by a threaded connection.

[0042] Embodiment 2

[0043] Please refer to Figure 4 The main difference between this embodiment and the first embodiment is that the pressure ring 6 is a split structure, and the pressure ring 6 includes two sub-blocks. Figure 4 It is a sub-block close to the hollow screw 4. The two first conical surfaces 61 are respectively arranged on the two sub-blocks. The two sub-blocks can be selected with different materials and structures according to actual working conditions to improve the scope of application and assembly flexibility.

[0044] For further information, please refer to Figure 4 The pressure ring 6 is provided with a shoulder 63 that matches the end face of the hollow screw 4. When the shoulder 63 abuts against the end face of the hollow screw 4, the relative position between the pressure ring 6 and the hollow screw 4 can be limited to prevent the pressure ring 6 from extending too much into the hollow screw 4, thereby avoiding excessive deformation of the end of the pressure ring 6. Similarly, the pressure ring 6 can also be provided with a shoulder 63 that matches the end face of the joint core 2, which can limit the relative position between the pressure ring 6 and the joint core 2.

[0045] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
