Description

Technical Field

[0001] The invention belongs to the technical field of heat energy recovery, in particular to an automatically operated calcium carbide sensible heat collecting device. Background Art

[0002] As we all know, when calcium carbide is discharged from the calcium carbide furnace, it is usually received in a calcium carbide trolley, which is then transported to the corresponding place for cooling by manual handling or mechanical transportation. Calcium carbide is at a high temperature of hundreds or even thousands of degrees. During the cooling process, it releases a large amount of heat. If this heat is not collected, on the one hand, it will have a greater impact on the ambient temperature, which is not conducive to workers' operations, and on the other hand, it will cause energy waste. Although people have conducted various studies on heat collecting covers, there are no technical inspirations or specific technical solutions applied to the calcium carbide field.

[0003] In the traditional calcium carbide production process, when calcium carbide comes out of the furnace, the furnace trolley carries the calcium carbide pot, and the traction device leads the calcium carbide pot to the calcium carbide furnace outlet. When it comes out of the furnace, the molten calcium carbide flows into each calcium carbide pot. At this time, the temperature of the liquid calcium carbide is above 1300°C. After coming out of the furnace, the calcium carbide pot filled with calcium carbide melt is pulled into the cooling workshop for cooling. When the temperature drops to about 400°C, the calcium carbide solidifies into shape, is lifted out of the calcium carbide pot, and transported to the storage workshop for further cooling. The heat generated by the entire cooling process of the calcium carbide is completely dissipated, resulting in energy waste, which is not conducive to energy conservation and emission reduction.

[0004] To this end, the present invention provides an automatically operated calcium carbide sensible heat collecting device. Summary of the Invention

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] Example 1: Figures 1 to 9 As shown, an automatically operated calcium carbide sensible heat collection device described in an embodiment of the present invention includes a device body 1, an insulation layer 2 is fixedly installed on the inner wall of the upper end of the device body 1, a reaction chamber 3 is fixedly installed in the insulation layer 2, a heat pipe 4 is fixedly installed on the inner wall of the upper end of the reaction chamber 3, a conversion part 5 is fixedly installed on the upper end of the heat pipe 4, an equipment rack 6 is fixedly installed on the rear side of the device body 1, a heat collection component for heat energy recovery is arranged in the equipment rack 6, a conveying component for loading and unloading molten calcium carbide is arranged at the lower end of the device body 1, and a loading and unloading component for lifting a container for holding molten calcium carbide is arranged in the device body 1.

[0034] The melted calcium carbide is delivered into the device body 1 through the conveying component, and the melted calcium carbide is lifted and connected to the lower end opening of the insulation layer 2 and the reaction chamber 3 through the loading and unloading component. The insulation layer 2 and the reaction chamber 3 collect the sensible heat generated by the melted calcium carbide, and the fluid passing through the heat pipe 4 efficiently absorbs the sensible heat released by the calcium carbide reaction, and the high-temperature fluid is heat-exchanged with the external medium through the heat collecting component, thereby transferring the sensible heat to the power generation equipment or the heating equipment, thereby realizing multiple utilization of sensible heat, and the insulation layer 2 and the reaction chamber 3 are made of chromium-nickel alloy and aluminum silicate fiber respectively, which can effectively reduce heat loss and improve the thermal efficiency of the device. It can withstand the high temperature and chemical corrosion generated by the calcium carbide reaction, and the reaction chamber 3 is designed as a sealed structure to ensure that the calcium carbide reaction is carried out in a closed environment to prevent heat loss and leakage of harmful gases, and can realize automatic loading and unloading of calcium carbide, realize the integration and automation effect of the equipment, and can significantly improve production efficiency and operation convenience. This design not only saves space, but also reduces the transmission and conversion time between equipment, making the entire process smoother.

[0035] like Figures 1 to 2 As shown, the heat collecting assembly includes two groups of suction pumps 7, which are fixedly installed in the lower end of the equipment frame 6, and a return pipe 8 is fixedly installed in the rear end of the equipment frame 6 through a clamp. The lower end of the return pipe 8 is fixedly connected to the two groups of suction pumps 7, and a heat exchanger 9 is fixedly installed in the left end of the equipment frame 6 through a clamp. The lower end of the heat exchanger 9 is connected to the two groups of suction pumps 7, and a first delivery pipe 10 is fixedly installed on the right side of the upper end of the heat exchanger 9 through a flange. A first solenoid valve 11 is provided at the connection between the first delivery pipe 10 and the heat exchanger 9, a second solenoid valve 12 is installed on the left side of the lower end of the heat exchanger 9 through a flange, a discharge pipe 13 is installed on the left end of the second solenoid valve 12 through a flange, and a second delivery pipe 14 is provided at the upper end of the heat exchanger 9.

[0036] After the fluid in the heat pipe 4 absorbs the high temperature generated by the melted calcium carbide, the hot fluid flows into the heat exchanger 9 through the first delivery pipe 10, and the external medium flows into the heat exchanger 9 through the second delivery pipe 14. The external medium entering the heat exchanger 9 exchanges heat with the high-temperature fluid, and the medium temperature rises rapidly. The high-temperature medium flows out to the power generation equipment or heating equipment through the second solenoid valve 12 and the discharge pipe 13. After releasing heat, the high-temperature medium becomes a low-temperature medium and returns to the heat pipe 4 through two sets of suction pumps 7 and the return pipe 8, completing the closed cycle, thereby completing the function of collecting the sensible heat of the melted calcium carbide.

[0037] like Figures 1 to 6As shown, the conveying assembly includes two groups of conveying seats 15, and the two groups of conveying seats 15 are symmetrically installed on the left and right sides of the lower end of the device body 1. The first screw rod 16 is rotatably installed in the two groups of conveying seats 15, and the first motor 17 is fixedly installed on the opposite ends of the left and right sides of the two groups of conveying seats 15. The output shafts of the two groups of first motors 17 are fixedly connected to the two groups of first screw rods 16. Two groups of limiting guide rails 18 are fixedly installed on the upper sides of the two groups of conveying seats 15, and mounting seats 19 are threadedly installed on the two groups of first screw rods 16. Multiple groups of sliders 20 are symmetrically installed on the lower sides of the two groups of mounting seats 19. The multiple groups of sliders 20 on the lower sides of the two groups of mounting seats 19 are slidably installed on the two groups of second motors 28 on the upper sides of the two groups of first splints 25. A bracket 21 is fixedly installed on the upper sides of the two groups of mounting seats 19, and the upper ends of the two groups of brackets 21 are provided with clamping components for loading and unloading calcium carbide.

[0038] By the forward rotation of the output shafts of the two first motors 17, the two first screw rods 16 can be driven to rotate in the two conveying seats 15. When the two first screw rods 16 rotate forward and reverse, the two mounting seats 19 can be driven to move left and right on the two first screw rods 16. When it is necessary to load the molten calcium carbide, the two mounting seats 19 move left and right to drive the clamping assembly to move, and then the molten calcium carbide is transported into the device body 1. Then, the calcium carbide pot 27 is lifted by the loading and unloading assembly. When it is necessary to unload the calcium carbide pot 27, the above steps can be reversed, thereby achieving the purpose of automatic loading and unloading of the melted calcium carbide.

[0039] like Figures 5 and 6 As shown, the clamping assembly includes two groups of mounting plates 22, and the two groups of mounting plates 22 are respectively fixedly mounted on the upper sides of the two groups of brackets 21, and brackets 23 are fixedly mounted on the opposite sides of the two groups of mounting plates 22. First movable grooves 24 are symmetrically opened in the two groups of brackets 23, and first clamping plates 25 are slidably mounted in the first movable grooves 24 at the left and right ends of the two groups of brackets 23. Second screw rods 26 are inserted through threads at the left and right ends of the two groups of brackets 23, and the second screw rods 26 at the left and right ends of the two groups of brackets 23 are respectively rotatably connected to the first clamping plates 25 installed in the first movable grooves 24 at the left and right ends of the two groups of brackets 23, and calcium carbide pots 27 are provided in the two groups of brackets 23.

[0040] When it is necessary to clamp the calcium carbide pot 27 containing molten calcium carbide, when the two groups of second screw rods 26 at the left and right ends of the two groups of brackets 23 rotate, the two groups of first clamping plates 25 can be driven to slide in the two groups of first movable grooves 24, thereby clamping the calcium carbide pot 27. When it is necessary to loosen the calcium carbide pot 27, the two groups of second screw rods 26 are rotated in the opposite direction, so that the two groups of first clamping plates 25 slide to both sides in the two groups of first movable grooves 24, and the calcium carbide pot 27 can be loosened, thereby facilitating the clamping and loosening of the calcium carbide pot 27, facilitating the loading and unloading of the molten calcium carbide, and ensuring the stability of the transportation of the calcium carbide pot 27.

[0041] like Figures 3 to 7 As shown, the loading and unloading assembly includes a second motor 28, which is fixedly mounted on the front side of the device body 1, and a rotating shaft 29 is rotatably mounted in the device body 1. The front end of the rotating shaft 29 is fixedly connected to the output shaft of the second motor 28, and a turntable frame 30 is fixedly mounted on the rotating shaft 29. Four groups of first grooves 31 are provided on the turntable frame 30, and four groups of positioning plates 32 are fixedly mounted on the front and rear sides of the turntable frame 30. Electric push rods 33 are fixedly mounted on the four groups of positioning plates 32 on the front and rear sides of the turntable frame 30, and balance frames 34 are rotatably mounted on the telescopic ends of the eight groups of electric push rods 33 installed on the front and rear sides of the turntable frame 30. Second clamping plates 35 are fixedly mounted on the opposite sides of the eight groups of balance frames 34, and the eight groups of second clamping plates 35 are all in the four groups of first grooves 31.

[0042] When it is necessary to lift the calcium carbide pot 27 clamped by the clamping assembly, the output shaft of the second motor 28 drives the rotating shaft 29 and the turntable frame 30 to rotate. When the two groups of second clamping plates 35 in the four groups of first grooves 31 rotate to the upper end of the calcium carbide pot 27 in turn and are flush with the upper end of the calcium carbide pot 27, the telescopic ends of the two groups of electric push rods 33 drive the two groups of balance frames 34 and the two groups of second clamping plates 35 in the first grooves 31 to move and clamp the calcium carbide pot 27. Then the second motor 28 continues to drive the turntable frame 30 to rotate, thereby lifting the clamped calcium carbide pot 27, thereby aligning the calcium carbide pot 27 with the lower end openings of the insulation layer 2 and the reaction chamber 3, so as to facilitate the sensible heat generated by the melted calcium carbide in the insulation layer 2 and the reaction chamber 3. The heat is collected in the cavity 3, which ensures the efficiency of heat recovery, and can continuously and accurately lift or lower multiple groups of calcium carbide pots 27, thereby realizing the separation of one group of calcium carbide pots 27 from the reaction cavity 3. At the same time, the other group of calcium carbide pots 27 can be synchronously lifted and approached to the reaction cavity 3, and finally fit tightly with the reaction cavity 3, ensuring the efficiency and smoothness of the whole process, and ensuring the continuous operation of the calcium carbide sensible heat collection device. The calcium carbide pots 27 are clamped and lifted by two groups of balancing frames 34 and two groups of second splints 35 in the first groove 31. The two groups of balancing frames 34 and two groups of second splints 35 are simultaneously affected by gravity and centripetal force, so that the center of gravity of the calcium carbide pots 27 clamped by the two groups of balancing frames 34 and two groups of second splints 35 always remains in a downward state.

[0043] like Figures 3 to 7 As shown, the cross section of the turntable frame 30 is cross-shaped, and the front-to-back width of the inner wall of the four groups of first grooves 31 on the turntable frame 30 is greater than the outer wall diameter of the bracket 23.

[0044] When the rotating shaft 29 and the turntable frame 30 rotate, the four groups of first grooves 31 can smoothly bypass the bracket 23 without interference or collision, ensuring the smoothness and reliability of operation. At the same time, the larger inner wall width also provides sufficient space, so that the second clamping plate 35 can have sufficient flexibility and adaptability when clamping the calcium carbide pot 27, further improving the stability and accuracy of clamping.

[0045] like Figures 6 and 7 As shown, the inner walls of the four groups of first clamping plates 25 and the symmetrical sides of the eight groups of second clamping plates 35 installed in the two groups of brackets 23 are all provided with anti-slip pads made of ceramic fiber.

[0046] Ceramic fiber has good high temperature resistance and excellent anti-slip performance, which can effectively increase the friction between the inner wall of the first clamping plate 25 and the second clamping plate 35 and the calcium carbide pot 27, preventing the calcium carbide pot 27 from sliding or falling off during the clamping and lifting process, thereby further improving the stability and safety of clamping. At the same time, the ceramic fiber material also has good wear resistance and corrosion resistance, and can maintain its excellent physical and chemical properties for a long time, thereby extending the service life of the clamping components and loading and unloading components.

[0047] like Figures 4 to 9 As shown, a third motor 36 is fixedly installed in the upper end of the device body 1, a first synchronous wheel 37 is rotatably installed in the upper end of the device body 1, the output shaft of the third motor 36 is fixedly connected to the first synchronous wheel 37, two sets of second synchronous wheels 38 are rotatably installed in the upper end of the device body 1, a synchronous belt 39 is sleeved on the first synchronous wheel 37 and the two sets of second synchronous wheels 38, a third screw rod 40 is inserted into the two sets of second synchronous wheels 38 through a thread, and a positioning frame 41 is symmetrically installed on the inner wall of the upper end of the device body 1, and a second movable groove is opened in the two sets of positioning frames 41 42, the lower ends of the two groups of third screw rods 40 are inserted into the two groups of second movable grooves 42, and connecting plates 43 are slidably installed in the two groups of second movable grooves 42. The lower ends of the two groups of third screw rods 40 are rotatably connected with the two groups of connecting plates 43, and two groups of connecting rods 45 are rotatably installed on the lower sides of the two groups of connecting plates 43. Sealing plates 46 are rotatably installed on the lower sides of the left and right ends of the thermal insulation layer 2. The lower ends of the two groups of connecting rods 45 installed on the lower sides of the two groups of connecting plates 43 are respectively rotatably connected to the lower end outer walls of the two groups of sealing plates 46, and through holes 47 are opened at the joints of the front and rear ends of the two groups of sealing plates 46.

[0048] When the calcium carbide pot 27 needs to be sealed, the output shaft of the third motor 36 starts to drive the first synchronous wheel 37, the two sets of second synchronous wheels 38 and the synchronous belt 39 to rotate together. Since the two sets of third screw rods 40 are connected to the synchronous belt 39 by threads, the rotation of the synchronous belt 39 will be converted into the vertical movement of the two sets of third screw rods 40. As the lower ends of the two sets of third screw rods 40 slide in the two sets of second movable grooves 42, the two sets of connecting plates 43 also slide accordingly, thereby driving the two sets of connecting rods 45 installed at the lower end and the two sets of sealing plates 46 installed on the lower side of the left and right ends of the insulation layer 2 to rotate. When the two sets of sealing plates 46 are fully closed, they fit tightly against the outer wall of the calcium carbide pot 27, forming an effective sealing barrier. At the same time, it can further enhance the sealing effect when the calcium carbide pot 27 is docked with the insulation layer 2 and the reaction chamber 3, preventing heat from dissipating from the gap during the transfer process.

[0049] like Figures 4 to 9 As shown, guide rods 44 are symmetrically installed on the upper sides of the two groups of connecting plates 43 , and the two groups of guide rods 44 installed on the upper sides of the two groups of connecting plates 43 are movably inserted into the two groups of second movable grooves 42 .

[0050] By installing the guide rod 44 on the upper side of the connecting plate 43, the connecting plate 43 is guided at the front and rear ends when sliding up and down in the second movable groove 42, avoiding the front and rear ends from tilting and offsetting when the connecting plate 43 slides, thereby ensuring the stability and accuracy of the sliding of the connecting plate 43. In addition, the design of the guide rod 44 also enhances the structural strength of the connecting plate 43.

[0051] like Figures 1 to 4 As shown, the cross-sections of the lower ends of the two sets of sealing plates 46 are both L-shaped, the inner wall diameters of the lower ends of the two sets of sealing plates 46 are the same as the outer wall diameters of the lower ends of the calcium carbide pot 27, and the lower end opening diameter of the reaction chamber 3 is the same as the upper end opening diameter of the calcium carbide pot 27.

[0052] When the sealing plate 46 is completely closed and fits tightly against the outer wall of the calcium carbide pot 27, a stable and sealed connection can be formed to prevent heat from being lost from the connection during the transfer process, thereby ensuring the efficient operation of the heat recovery system. At the same time, the L-shaped cross-sectional design also increases the contact area between the sealing plate 46 and the calcium carbide pot 27, further enhancing the stability and sealing of the connection. In addition, the opening diameter of the lower end of the reaction chamber 3 is the same as the opening diameter of the upper end of the calcium carbide pot 27, ensuring that the calcium carbide pot 27 can be smoothly and tightly docked with the reaction chamber 3, so that the heat generated by the molten calcium carbide can be efficiently transferred to the fluid in the heat pipe 4, thereby realizing the collection and utilization of sensible heat.

[0053] Working principle: Place the calcium carbide pot 27 containing calcium carbide in the bracket 23 of the conveying assembly, and twist the two groups of second screw rods 26 on the bracket 23, thereby driving the two groups of first clamps 25 to slide and fit tightly with the outer wall of the calcium carbide pot 27, and drive the first screw rod 16 to rotate through the output shaft of the first motor 17 installed on the conveying seat 15 at the left end of the device body 1. The rotation of the first screw rod 16 drives the mounting seat 19, multiple groups of sliders 20, bracket 21 and mounting plate 22 to move, and then the calcium carbide pot 27 placed in the bracket 23 is transported into the device body 1. When the calcium carbide pot 27 moves to the right end of the conveying seat 15 at the left end of the device body 1, the output shaft of the second motor 28 drives the rotating shaft 29 and the turntable frame 30 to rotate, and the turntable frame 30 rotates to move the first groove 31 The opening is flush with the calcium carbide pot 27, and the telescopic ends of the two groups of electric push rods 33 flush with the calcium carbide pot 27 drive the two groups of balance frames 34 and the two groups of second clamps 35 to slide and fit into the outer wall of the calcium carbide pot 27, thereby clamping and fixing the calcium carbide pot 27. Then the output shaft of the second motor 28 continues to drive the rotating shaft 29 and the turntable frame 30 to rotate, thereby driving the clamped calcium carbide pot 27 to lift and fit into the lower end opening of the insulation layer 2 and the reaction chamber 3. After the calcium carbide pot 27 is docked with the lower end opening of the insulation layer 2 and the reaction chamber 3, the output shaft of the third motor 36 drives the first synchronous wheel 37 and the two groups of second synchronous wheels 38 and the synchronous belt 39 to rotate, thereby driving the two groups of third screw rods 40 to slide downward, and driving the two groups of connecting plates 43 in the two groups of second movable grooves 42. Slide downward, and as the two groups of connecting plates 43 slide downward, the two groups of sealing plates 46 installed on the left and right sides of the lower end of the insulation layer 2 are driven by the two groups of connecting rods 45 installed at the lower ends to rotate and close, and the two closed groups of sealing plates 46 are in contact with the outer wall of the calcium carbide pot 27, so that the insulation layer 2 and the reaction chamber 3 and the calcium carbide pot 27 can be sealed. The fluid flowing in the heat pipe 4 in the reaction chamber 3 absorbs the sensible heat released by the calcium carbide reaction in the calcium carbide pot 27, and the fluid flowing in the heat pipe 4 is returned from the first delivery pipe 10 into the heat exchanger 9 through the two groups of suction pumps 7. The external medium flowing in from the second delivery pipe 14 exchanges heat with the high-temperature fluid, and the medium after heat exchange with the high-temperature fluid flows out from the second solenoid valve 12 and the discharge pipe 13 to the power generation equipment or The heating equipment, after heat exchange with the medium, the fluid flows back into the heat pipe 4 through two sets of suction pumps 7 and the reflux pipe 8, and then continuously absorbs the sensible heat released by the calcium carbide reaction. After the calcium carbide in the calcium carbide pot 27 cools down, the two sets of sealing plates 46 are driven to rotate and open, and then the output shaft of the second motor 28 drives the rotating shaft 29 and the turntable frame 30 to rotate to separate the calcium carbide pot 27 from the insulation layer 2 and the reaction chamber 3 and move it to the conveying seat 15 on the lower right side of the device body 1, and the calcium carbide pot 27 is inserted on the bracket 23 in the right end of the device body 1, and then the output shaft of the first motor 17 on the conveying seat 15 on the lower right side of the device body 1 drives the first screw 16 to rotate, and then the rotating shaft 29, the bracket 21, the mounting plate 22 and the bracket 23 are moved out.Repeat the above operation to continuously collect the sensible heat released by the calcium carbide reaction.
