Description

Technical Field

[0001] The present invention relates to the technical field of zincizing equipment, and more specifically, to a precise temperature-controlled nano alloy co-infiltration furnace. Background Art

[0002] Multi-element alloy co-infiltration technology is a method of improving the surface properties of metals by simultaneously infiltrating multiple alloy elements into the metal surface. This technology utilizes the chemical and physical effects between alloy elements and metal matrix, and through heat treatment, diffusion and other processes, the alloy elements and metal matrix form a strong metallurgical bond, thereby improving the hardness, wear resistance, corrosion resistance and other properties of the metal surface.

[0003] For example, the authorization announcement number CN 106399924 A discloses a fully mixed and contacted multi-element alloy co-penetration furnace, which packs metal plates into bundles and sets four groups of fixed clamping protrusions to prevent the metal plates from being displaced and collided with each other, and the positions of the metal plates packed into bundles and the rotating heating tank are relatively stable. On the one hand, the friction and impact between the metal plates and the rotating heating tank are reduced, and on the other hand, the metal plates and the rotating heating tank can be made to rotate synchronously, thereby significantly improving the contact and mixing of the metal plates and the co-penetration agent, that is, the uniformity of the multi-element alloy co-penetration treatment can be improved, and weak anti-corrosion positions on the metal plates can be avoided; the glass fiber cloth can well buffer the impact force between the metal plates packed into bundles and the inner wall of the rotating heating tank when the rotating heating tank rotates, thereby further reducing wear and deformation.

[0004] During the use of the above scheme, due to the large space in the co-infiltration furnace, different areas may have different temperatures, which will affect the content of alloy elements in the infiltrated metal, resulting in uneven infiltration, and further affecting the qualified rate of the product. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a precise temperature-controlled nano-alloy co-infiltration furnace capable of precisely adjusting the temperature in the furnace.

[0006] To achieve the above object, the present invention provides the following technical solutions: A precise temperature-controlled nano alloy co-infiltration furnace comprises a co-infiltration furnace body, wherein an interlayer is arranged in the co-infiltration furnace body. The co-infiltration furnace body is provided with a controller, which includes a central processing module, a sensing module, a signal receiving module and a signal output module. The central processing module is coupled with the sensing module, the signal receiving module and the signal output module. The central processing module is a PC terminal. The induction module is associated with an induction device, which is placed in the infiltration furnace body. The induction device includes an assembly tube and a plurality of temperature sensors arranged equidistantly in the assembly tube. The ends of the temperature sensors are electrically connected to induction probes. The assembly tube is fixedly connected to the infiltration furnace body. The signal output module is associated with a temperature control device, which includes a plurality of groups of heating tubes arranged on the inner wall of the interlayer, and each group of heating tubes is electrically connected to a temperature sensor.

[0007] The present invention is further configured as follows: a connecting rod is provided in the assembly tube, springs 1 are equidistantly distributed on the connecting rod, and the other end of the spring 1 is connected to a temperature sensor. The outer wall of the assembly tube is provided with a number of annular grooves at equal intervals, and the number of the annular grooves is twice the number of the temperature sensors. A push cylinder is connected to one end of the connecting rod, and the output end of the push cylinder is connected to the connecting rod. A through groove for placing a pushing cylinder is provided on the side wall of the co-infiltration furnace body.

[0008] The present invention is further configured as follows: an electric telescopic rod is provided on the inner wall of the assembly tube, and an output end of the electric telescopic rod is connected to a push cylinder. The output end of the electric telescopic rod is connected with a cleaning ring, which contacts the inner wall of the assembly tube.

[0009] The present invention is further configured as follows: a second spring is provided at one end of the connecting rod relative to the pushing cylinder, and the other end of the second spring is fixedly connected to the inner wall of the co-infiltration furnace.

[0010] The present invention is further configured as follows: the cleaning ring comprises a connecting frame and a cleaning cloth connected to the connecting frame, a hook surface is adhered to the connecting frame, and an end surface of the cleaning cloth is provided with a fur surface, and the fur surface is hooked with the hook surface.

[0011] The present invention is further configured such that: the installation position of the electric telescopic rod is located on one side of the annular groove.

[0012] The present invention is further configured as follows: the assembly pipe, the connecting rod and the telescopic rod are all made of high temperature resistant materials.

[0013] Compared with the shortcomings of the prior art, the beneficial effects of the present invention are: By adding a controller and a temperature control device, the local temperature inside the infiltration furnace body can be adjusted according to demand, and the furnace body can be divided into multiple uniform areas. By setting a positioning temperature sensor inside the through pipe, it can be determined according to demand that the temperature of each area is not enough. For the insufficient places, feedback instructions can be given to start the heating area heating device of the corresponding area to increase the temperature. Furthermore, by pushing the cylinder to change the position of the temperature sensor and calculating the temperature difference between two adjacent ring grooves, the temperature can be finely adjusted. Furthermore, the inner wall of the assembly tube can be cleaned by pulling the cleaning ring through the electric telescopic rod. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] like Figures 1 to 3 As shown, A precise temperature-controlled nano alloy co-infiltration furnace comprises a co-infiltration furnace body 1, an interlayer 2 is arranged in the co-infiltration furnace body 1, and a controller is arranged on the co-infiltration furnace body 1.

[0019] The controller includes a central processing module, a sensing module, a signal receiving module and a signal output module. The central processing module is coupled with the sensing module, the signal receiving module and the signal output module. The central processing module is a PC end, and the working status of the following devices is adjusted through the controller.

[0020] The sensing module is associated with a sensing device, which is placed in the co-infiltration furnace body 1. The signal output module is associated with a temperature control device, which includes several groups of heating tubes 6 arranged on the inner wall of the interlayer 2. Each group of heating tubes 6 is electrically connected to a temperature sensor 4, and the temperature at the corresponding position is sensed by the temperature sensor 4.

[0021] The sensing device includes an assembly tube 3 and a plurality of equidistantly arranged temperature sensors 4 placed in the assembly tube 3. The end of the temperature sensor 4 is electrically connected to a sensing probe 5. The assembly tube 3 is fixedly connected to the co-infiltration furnace body 1. The sensing probe 5 can extend out of the assembly tube 3 to make the measurement more accurate.

[0022] A connecting rod 7 is provided in the assembly tube 3, and a spring 13 is provided at one end of the connecting rod 7 relative to the pushing cylinder 10. The other end of the spring 13 is fixedly connected to the inner wall of the co-infiltration furnace. The length of the connecting rod 7 can be changed by squeezing or stretching the spring, thereby changing the position of the temperature sensor 4 on the connecting rod 7.

[0023] A number of annular grooves 9 are equidistantly provided on the outer wall of the assembly tube 3, and the number of the annular grooves 9 is twice the number of the temperature sensors 4. A pushing cylinder 10 is connected to one end of the connecting rod 7, and a through groove for placing the pushing cylinder 10 is provided on the side wall of the co-infiltration furnace body 1. The output end of the pushing cylinder 10 is connected to the connecting rod 7. By moving the position of the temperature sensor 4, the temperature difference between two adjacent annular grooves 9 is calculated to achieve the purpose of refined measurement.

[0024] Springs 8 are evenly distributed on the connecting rod 7, and the other end of the spring 8 is connected to the temperature sensor 4. Since the spring is elastic, when the connecting rod 7 moves, the spring 8 is squeezed, and at this time, the temperature sensor 4 retracts into the assembly tube 3.

[0025] An electric telescopic rod 11 is provided on the inner wall of the assembly tube 3 , the output end of the electric telescopic rod 11 is connected to the push cylinder 10 , and the installation position of the electric telescopic rod 11 is on one side of the annular groove 9 to prevent the electric telescopic rod 11 from affecting the operation of the temperature sensor 4 .

[0026] A cleaning ring 12 is connected to the output end of the electric telescopic rod 11, and the cleaning ring 12 contacts the inner wall of the assembly tube 3. The cleaning ring 12 includes a connecting frame 14 and a cleaning cloth 15 connected to the connecting frame 14, which can clean the inner wall of the assembly tube 3 to prevent dust from affecting the operation of the temperature sensor 4.

[0027] A hook surface is adhered to the connecting frame 14, and a fur surface is provided on the end surface of the cleaning cloth 15, and the fur surface is hooked with the hook surface, so that the cleaning cloth 15 can be replaced at a later stage.

[0028] The assembly tube 3, the connecting rod 7 and the telescopic rod are all made of high temperature resistant materials and have a longer service life.

[0029] Working principle: When in use, first place the material in the co-infiltration furnace body 1. At this time, the temperature sensor 4 can sense the temperature of the corresponding position, and set the interval time for pushing the cylinder 10 to work on the PC end. When the cylinder 10 is working, the connecting rod 7 is pushed to move. Since one end of the connecting rod 7 has a spring 13, the length of the connecting rod 7 can be changed according to the characteristics of the spring. Under the action of pressure, the spring 8 is compressed, and the sensing probe 5 is retracted into the assembly tube 3. When it reaches the next annular groove 9, under the elastic force of the spring 8, the sensing probe 5 extends out of the annular groove 9. At this time, the central processing module receives the data of the two temperatures, records the temperature difference, and then controls the start of the heating tube 6 through the obtained data to adjust the temperature of the corresponding position.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
