Description

Technical Field

[0001] The invention relates to the technical field of reactors, and in particular to a zirconium-titanium steel composite reactor. Background Art

[0002] It is well known that the zirconium-titanium steel composite reactor is a common chemical equipment and is mainly made of zirconium-titanium steel composite materials. It is mainly used in chemical reactions, catalytic reactions, high-temperature pyrolysis, hydrolysis, oxidation-reduction and other process. During the use of the reactor, a thermocouple is set inside to measure and control the heat generated in the chemical reaction.

[0003] The patent document with application number CN202210734758.2 and application date 2022.06.27 and titled "A Reactor" includes a reactor body, a stirring shaft, a stirrer, and a thermocouple. A temperature measuring sleeve higher than the thermocouple temperature measuring head is coaxially sleeved on the thermocouple, so that it includes a main body in the shape of a regular triangular prism and a sealing plate connected to the upper end face of the main body. The upper end of the main body is connected to the inner wall of the reactor body through a fixing device, and the lower end of the main body is gradually retracted downward and pressed against the outer wall of the thermocouple, so that one side wall of the main body is parallel to The virtual plane formed by the axis line of the temperature measuring sleeve and the axis line of the stirring shaft can not only make the temperature measuring sleeve have higher strength, but also use the temperature measuring sleeve to resist the impact of material flow and avoid damage to the thermocouple. It can also form a closed temperature insulation cavity between the temperature measuring sleeve and the thermocouple to avoid temperature transfer of the material above the temperature measuring point and accurately measure the temperature. The side wall of the main body parallel to the above virtual plane or the tip of the opposite side of the side wall can be used to divert the material flow and guide it to the agitator to improve the stirring effect, and the side wall of the main body can be used to achieve a stable connection with the fixing device.

[0004] In the above patent, although most of the thermocouple is protected by setting a temperature measuring sleeve to avoid damage to the thermocouple caused by the impact of the reaction material, the detection part at the bottom is not covered because the material needs to be detected in real time, and is exposed to the outside. When the material is deposited at the bottom of the stirred reactor, the material will continuously and vertically impact the detection part of the thermocouple, which is easy to cause damage to the thermocouple.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-9 As shown, a zirconium-titanium steel composite reactor provided in this embodiment includes a reactor body 1, wherein a stirring mechanism and a thermocouple mechanism are arranged inside the reactor body 1, wherein the thermocouple mechanism includes a first sleeve 2 extending from the top to the bottom of the reactor body 1 and a temperature detection part arranged at the bottom of the first sleeve 2, wherein the bottom end of the bottom of the first sleeve 2 is rotatably connected to a second sleeve 3, wherein the second sleeve 3 is circumferentially covered on the outside of the temperature detection part, and a blade group 4 is arranged inside the second sleeve 3 so that when the second sleeve 3 is driven to rotate, the reactant can be driven to be drained along the axial direction of the temperature detection part.

[0032] Specifically, the kettle body 1 is made of zirconium-titanium steel composite material, and the kettle body 1 is arranged vertically, and a discharge pipe is arranged at the bottom thereof, and the discharge pipe is used to discharge the materials that have completed the reaction inside the kettle body 1. A feed bin is arranged on the top of the kettle body 1, and the feed bin is used to put the reactants into the kettle body 1 for reaction. A plurality of supporting legs are arranged at the bottom of the kettle body 1 and around the discharge pipe, and the plurality of supporting legs are fixed to a fixed foundation such as the ground; the interior of the kettle body 1 provides a space for the reaction materials to react and stir, so that a stirring mechanism and a thermocouple mechanism are respectively arranged inside the kettle body 1, and the stirring mechanism and the thermocouple mechanism are immersed in the reactants inside the kettle body 1, so that on the one hand, the stirring mechanism stirs the reactants, and on the other hand, the thermocouple mechanism performs temperature measurement operation on the reactants;

[0033] The stirring mechanism is used to stir the reactants put into the kettle body 1 so that the reactants react, and the stirring mechanism includes a stirring blade 5 and a driving unit such as a motor 6, that is, the motor 6 is used to drive the stirring blade 5 to perform horizontal rotational movement to achieve a stirring action, so that the reactants inside the kettle body 1 are stirred, wherein the working direction of the stirring blade 5 is to rotate around the stirring shaft (that is, the output shaft of the motor 6) to achieve stirring of the reactants, and the stirring blade 5 is arranged on the output shaft of the motor 6, and the motor 6 is arranged on the top of the kettle body 1 and arranged vertically, and the stirring blade 5 is suspended inside the kettle body 1, so that the stirring blade 5 is driven to rotate inside the kettle body 1 by starting the motor 6 to stir the reaction materials inside the kettle body 1;

[0034] The thermocouple mechanism includes a first sleeve 2 extending from the top to the bottom of the kettle body 1 and a temperature detection part arranged at the bottom of the first sleeve 2; specifically, the first sleeve 2 is vertically arranged on one side of the stirring blade 5 and close to the vertical side wall of the kettle body 1, so as to avoid the stirring stroke of the stirring blade 5 and avoid obstruction of the stroke of the stirring blade 5; the temperature detection part is close to the bottom wall inside the kettle body 1, and is used to detect the temperature of the reactant at the bottom of the kettle body 1.

[0035] In the above description, the reactants are fed into the kettle body 1 through the feed bin, and the stirring blades 5 are driven by the motor 6 to rotate and stir the reactants so that the reactants react inside the kettle body 1. The temperature of the reactants in the stirring reaction is detected by the temperature detection part at the bottom of the thermocouple. After the stirring reaction is completed, the reactants are discharged from the kettle body 1 through the discharge pipe. The above are all existing technologies and will not be repeated.

[0036] The innovation in this embodiment is that the bottom end of the bottom of the first sleeve 2 is rotatably connected to the second sleeve 3, the second sleeve 3 is circumferentially covered on the outside of the temperature detection part, and a blade group is arranged in the second sleeve 3 so that when the second sleeve 3 is driven to rotate, the reactant can be driven to drain along the axial direction of the temperature detection part, that is, the vertical direction.

[0037] Specifically, the top and bottom of the second sleeve 3 are both opened, so that the reactants can flow into the interior of the second sleeve 3 from the top and be discharged from the bottom, so that the flow direction of the reactants at the temperature detection part is axial, reducing the direct impact on the temperature detection part, and the second sleeve 3 and the first sleeve 2 are both arranged vertically; the second sleeve 3 is rotatably connected to the bottom end of the first sleeve 2, and the diameter of the second sleeve 3 is larger than the diameter of the first sleeve 2, so that the second sleeve 3 covers the bottom end (temperature detection part) of the first sleeve 2 for protection; and the bottom end of the first sleeve 2 passes through the second sleeve 3 and extends to the interior of the second sleeve 3;

[0038] In this embodiment, an annular groove 4 is provided on the outer surface of the second sleeve 3, and a plurality of rotating blades 7 are arranged inside the annular groove 4, and the plurality of rotating blades 7 are annularly distributed in the annular groove 4, and the rotating blades 7 are arranged obliquely with respect to the radial surface of the second sleeve 3, that is, the rotating blades 7 are not perpendicular to the outer wall surface of the second sleeve 3, and the structure is similar to the principle of a turbine or a propeller, so that when the rotating reactant impacts the second sleeve 3, the second sleeve 3 can be driven to rotate as a whole by the arranged rotating blades 7, that is, when the stirring blades 5 rotate inside the kettle body 1, the reactant is rotated inside the kettle body 1, so that the stirred reactant performs a circumferential rotational motion inside the kettle body 1 to impact the surface of the rotating blades 7, and under the inertia of the impact force, the second sleeve 3 is driven to rotate on its own, so that when the reactant inertially impacts the plurality of rotating blades 7 in sequence and continuously, the second sleeve 3 is driven to rotate continuously on its own;

[0039] Two rotating rings 8 are arranged inside the second sleeve 3, and the two rotating rings 8 are arranged vertically in parallel, one of the rotating rings 8 is arranged at the top opening of the second sleeve 3, and the other rotating ring 8 is arranged at the middle position inside the second sleeve 3; the first sleeve 2 passes through the two rotating rings 8 in sequence and extends to the bottom of the rotating ring 8 below, so that the first sleeve 2 is rotatably connected with the two rotating rings 8;

[0040] It should be noted that the two rotating rings 8 are connecting parts for the second sleeve 3 to rotate on the outer surface of the first sleeve 2, which can allow the second sleeve 3 to rotate as a whole, and can also support the second sleeve 3 during the rotation process, so that the second sleeve 3 always rotates on the outer surface of the first sleeve 2 in an upright state, that is, a connecting part such as a plurality of connecting parts arranged in a circumferential array is provided between the inner wall of the second sleeve 3 and the rotating ring 8;

[0041] In the most preferred embodiment, the blade group includes a plurality of spiral blades 9, which are also the above-mentioned connecting members, that is, the inner wall of the second sleeve 3 and the rotating ring 8 are connected by means of the spiral blades 9, and the plurality of spiral blades 9 are respectively fixed to the outer surfaces of the two rotating rings 8, and the radial outer end of each spiral blade 9 is fixed to the inner side wall of the second sleeve 3, and the spiral blades 9 are provided with a guide slope 10, and the guide slope 10 is used to guide the reactants so that the reactants inside the second sleeve 3 flow from top to bottom or from bottom to top (spiral blades 9 with different shapes have different drainage effects, preferably from top to bottom to reduce direct impact on the bottom of the temperature detection part, which is a prior art and will not be repeated), that is, the reactants at the top of the second sleeve 3 flow to the temperature detection part for temperature detection;

[0042] It should be noted that when the second sleeve 3 is immersed in the reactants, the rotation of the second sleeve 3 drives the multiple spiral blades 9 to rotate synchronously, thereby transporting the reactants from above the spiral blades 9 to below the blade group, that is, the reactants are drained along the axial direction of the temperature detection part and contact the temperature detection part, thereby measuring the temperature of the stirred reactants.

[0043] In the above description, the second sleeve 3 has two states:

[0044] When the second sleeve 3 is in the first state, that is, the second sleeve 3 does not rotate, at this time, the second sleeve 3 is used to protect the temperature detection part;

[0045] When the second sleeve 3 is in the second state, that is, the second sleeve 3 rotates, at this time, the rotation of the second sleeve 3 drives the reactants inside it to flow, that is, the movement direction of the reactants is from the inner top to the bottom of the second sleeve 3 (or vice versa, the same below, no further description), so that the reactants contact the temperature detection part for temperature detection;

[0046] Specifically, when switching from the first state to the second state, the motor 6 is started to drive the stirring blade 5 to rotate, so as to stir the reactants inside the kettle body 1, so that the reactants generate impact force to continuously impact the multiple rotating blades 7 on the second sleeve 3, thereby driving the second sleeve 3 to rotate as a whole, and at the same time, the reactants in the second sleeve 3 are also driven to flow along the axial direction of the temperature detection part, that is, the reactants flow from the top of the second sleeve 3 to the bottom, so as to contact the temperature detection part, so as to realize the temperature measurement operation of the reactants;

[0047] The switching action from the first state to the second state is switched by the rotation of the stirring blade 5. Specifically, when the stirring blade 5 stirs the reactant, the motor 6 is first started to drive the stirring blade 5 to rotate, so as to stir the reactant inside the kettle body 1. During the stirring process, the stirring impact of the reactant impacts the multiple rotating blades 7, thereby driving the second sleeve 3 to rotate as a whole, and driving the multiple spiral blades 9 inside the second sleeve 3 to rotate synchronously, so that the reactant is driven to be drained along the axial direction of the temperature detection part, that is, the reactant flows from top to bottom inside the second sleeve 3, so that the reactant flows and contacts the temperature detection part, so as to detect its temperature.

[0048] Beneficial effects of this embodiment: by providing the second sleeve 3, the temperature detection part can be protected to prevent part of the material from directly impacting the temperature detection part vertically during the stirring process, which may easily cause damage to the temperature detection part, and by rotating the second sleeve 3, the reactants are drained from top to bottom inside the second sleeve 3, so that the reactants flow and contact the temperature detection part, thereby detecting its temperature, and at the same time greatly reducing the frontal impact of the material on the temperature detection part of the thermocouple.

[0049] For further information, see Figure 6-Figure 7 In the above embodiment, the temperature of the reactants at the bottom of the kettle body 1 is detected by the temperature detection unit, but the temperature detection unit cannot detect the temperature of the reactants in different layers inside the kettle body 1.

[0050] Based on this, in order to detect the temperature at different depths inside the kettle body 1, the present embodiment provides an adjustment structure, wherein a bidirectional spiral groove 11 is provided on the outer surface of the first sleeve 2, and a guide plate 12 is rotatably connected to one side of the rotating ring 8 through a rotating shaft, and the guide plate 12 is slidably connected to the inside of the bidirectional spiral groove 11; a support plate 13 is fixedly connected to the other side of the rotating ring 8, and the support plate 13 is slidably in contact with the outer surface of the first sleeve 2, and the support plate 13 is used to support the first sleeve 2.

[0051] Specifically, the bidirectional spiral groove 11 is a closed-loop structure formed by the direct superposition of two spiral groove structures in opposite directions (or different rotation directions), which is similar to the spiral groove structure on the bidirectional lead screw, and the spiral grooves in the two directions have the same depth; the shape of the guide piece 12 is an arc shape that matches the spiral groove structure, so that the guide piece 12 is adapted to the groove shape of the bidirectional spiral groove 11, so that the guide piece 12 can be slidably connected to the spiral grooves in the two directions of the bidirectional spiral groove 11, that is, the second sleeve 3 is driven to rotate and slide up and down reciprocatingly on the outer surface of the first sleeve 2. When the second sleeve 3 and the guide piece 12 slide upward and slide to the top of the spiral groove in one direction (at this time, the guide piece 12 cannot slide in the spiral groove in one direction), it slides into the spiral groove in the other direction, so that the guide piece 12 is passively swung, that is, the guide piece 12 slides along the spiral groove in the other direction, thereby driving the second sleeve 3 to rotate and slide downward on the first sleeve 2;

[0052] In the above description, the guide blade 12 swings back and forth, thereby entering into the spiral grooves in different directions in the bidirectional spiral groove 11, so that the second sleeve 3 can slide back and forth up and down on the outer surface of the first sleeve 2. It should be noted that the second sleeve 3 always rotates in the same direction, that is, the second sleeve 3 can slide back and forth up and down on the outer surface of the first sleeve 2, so that when the second sleeve 3 contacts the reactants of different reaction layers, the reactants of different reaction layers can be guided to the temperature detection part for temperature detection through the rotation (in the same direction) of the spiral blade 9; this embodiment can detect the temperature within a certain depth range, and the detection structure is relatively more scientific.

[0053] In this embodiment, the support sheet 13 is in an arc shape, and its width is greater than the groove width of the bidirectional spiral groove 11 so that it can slide on the outer wall surface of the first sleeve 2 as a whole, thereby matching the shape of the first sleeve 2. In this way, when the second sleeve 3 slides up and down on the outer surface of the first sleeve 2, the support sheet 13 provides stable support for the reciprocating up and down movement of the second sleeve 3, avoiding tilting to affect the sliding of the second sleeve 3 on the outer surface of the first sleeve 2, that is, the second sleeve 3 always maintains an upright state and slides up and down on the outer surface of the first sleeve 2.

[0054] In this embodiment, the two rotating rings 8 only need to be provided with a guide plate 12 and a support plate 13 on the upper rotating ring 8, and the other lower rotating ring 8 can still be a sleeve on the first sleeve 2, and a plurality of circular holes (not shown in the figure) are opened inside to discharge the reactants guided into the upper rotating ring 8 from the circular holes, so as to smoothly flow into the temperature detection part for temperature detection.

[0055] It should be noted that when the second sleeve 3 slides upward to the extreme position of the first sleeve 2, that is, the guide piece 12 switches from the spiral groove in one direction of the bidirectional spiral groove 11 to the spiral groove in the other direction, at this time, the bottom of the second sleeve 3 and the temperature detection part are on the same horizontal line, that is, the temperature detection part is still in the second sleeve 3 for protection; when the second sleeve 3 slides downward to the extreme position, that is, the bottom of the second sleeve 3 abuts against the bottom of the inner wall of the kettle body 1, so that in the above process, the second sleeve 3 is always covered on the bottom end of the first sleeve 2, so as to detect the temperature of the temperature detection part at the bottom end of the first sleeve.

[0056] Specifically, when the second sleeve 3 is driven to rotate, the guide piece 12 provided in the second sleeve 3 is driven to slide upward in the spiral groove in one direction of the bidirectional spiral groove 11, that is, the second sleeve 3 as a whole rotates and slides upward, so that the second sleeve 3 contacts different reactant layers, and under the rotation of the spiral blade 9, reactants at different depths are introduced into the temperature detection part for temperature detection;

[0057] When the guide piece 12 slides to the top of the spiral groove in one direction of the bidirectional spiral groove 11, it slides into the spiral groove in the other direction, and causes the guide piece 12 to swing passively, that is, the guide piece 12 slides into the spiral groove in the other direction and slides downward, thereby driving the second sleeve 3 to rotate and slide downward on the first sleeve 2, thereby realizing the temperature detection of different reactant layers.

[0058] For further information, see Figure 8-Figure 9 As shown, in the above embodiment, when the temperature of the reactants at different depths inside the kettle body 1 is detected by the set temperature detection part, since the first sleeve 2 is always in a static state in the kettle body 1, the reactants in the kettle body 1 are easy to adhere to the surface of the first sleeve 2, especially the bidirectional spiral groove 11.

[0059] Based on this, in order to clean the first sleeve 2, this embodiment provides a negative pressure limit cleaning mechanism, which includes a special-shaped sleeve 14, and the top of the rotating ring 8 is fixedly connected with the special-shaped sleeve 14, and the special-shaped sleeve 14 is sleeved on the outer surface of the first sleeve 2, and the special-shaped sleeve 14 includes a diffusion section, a negative pressure section and an inflow section in sequence from one end of the rotating ring 8 close to the bottom (that is, the bottom) to the end of the rotating ring 8 far from the bottom;

[0060] The inflow section is in the shape of an inverted truncated cone, and the radial dimension of the top is the largest, which is used to increase the flow rate of the reactant flowing into the special-shaped sleeve 14. The radial dimension of the negative pressure section is the smallest, that is, a reduced neck is formed in the middle, and a certain flow velocity pressure difference is formed between the two sections, that is, the reactant flowing into the special-shaped sleeve 14 generates a pressure difference (negative pressure) to accelerate the speed of the reactant flowing to the diffusion section. The diffusion section is in the shape of a truncated cone, and its radial dimension is larger than the negative pressure section. In this way, when the reactant flows to the diffusion section, the negative pressure section accelerates the flow rate of the reactant, and then guides the reactant to flow into the diffusion section, that is, the reactant flows downward and impacts the surface of the first sleeve 2. At the same time, the diffusion section has a negative pressure suction effect due to diffusion to comprehensively clean the reactant and prevent the reactant from adhering to the surface of the first sleeve 2, especially the bidirectional spiral groove 11; one end of the negative pressure section is connected to the diffusion section, and the other end is connected to the inflow section. The bottom of the diffusion section is fixed to the rotating ring 8 at the bottom;

[0061] It should be noted that the diameter of the negative pressure section is slightly larger than the diameter of the first sleeve, and is used to provide support for the second sleeve 3 during the up and down sliding process to avoid shaking. At the same time, it facilitates the reactants to flow from the negative pressure section into the diffusion section, and plays a role in drainage and guidance; the reactants flowing into the special-shaped sleeve 14 flow from the inflow section to the negative pressure section and then to the diffusion section, and finally flow from the diffusion section to the gap between the rotating ring 8 and the second sleeve, and are discharged from the gap, or a larger opening is set at the connection position of the rotating ring 8 and the diffusion section to discharge the reactants.

[0062] Specifically, during cleaning, the second sleeve 3 rotates, driven by the spiral blades 9, so that the reactants flow from top to bottom in the second sleeve 3, so that part of the reactants first flow into the inflow section of the special-shaped sleeve 14, and then flow into the negative pressure section. Due to the width difference between the two sections, a pressure difference is generated when the reactants flow into the negative pressure section, so as to accelerate the speed of the reactants flowing to the diffusion section, that is, the reactants flow downward and impact the surface of the first sleeve 2, thereby cleaning the reactants attached to the surface of the first sleeve 2;

[0063] When the second sleeve 3 slides downward to detect the temperature of the reactants at different depths in the kettle body 1, as the second sleeve 3 gradually slides downward, the rotating ring 8 below the second sleeve 3 gradually separates from the surface of the first sleeve 2, that is, the limiting guide for the second sleeve 3 during the sliding process is lost. In this way, in order to prevent the second sleeve 3 from sliding and tilting on the surface of the first sleeve 2, a special-shaped sleeve 14 is provided on the top of the rotating ring 8 below the second sleeve 3. When the second sleeve 3 continues to slide downward, the bottom of the first sleeve 2 can slide into the special-shaped sleeve 14. In this way, the negative pressure section inside the special-shaped sleeve 14 is close to the surface of the first sleeve 2, thereby limiting and guiding the second sleeve 3 during its downward sliding process, so that the second sleeve 3 always keeps sliding vertically on the surface of the first sleeve 2, avoiding the second sleeve 3 from tilting and shaking during the sliding process, thereby improving the stability during the sliding process.

[0064] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
