The tube sheet is cast by injecting the molten metal into a pre-designed mold. After the metal cools and solidifies, a tube sheet casting with a specific shape and structure can be obtained. The casting process of the tube sheet also requires strict control of parameters such as casting temperature, pressure and cooling rate to ensure the quality and performance of the casting. At the same time, with the continuous development of science and technology, modern heat exchanger casting equipment has also adopted many advanced technologies and processes, such as numerical simulation and automatic control, to improve production efficiency and product quality.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Cool the tube sheet with coolant and low-temperature air at the same time, so that the tube sheet is cooled evenly. The pressurized air contacts the tympanic membrane on the longitudinal plate through the connecting port. Since the longitudinal plate is cooled by the cooling end, the longitudinal plate reduces the temperature of the pressurized air through the tympanic membrane. After the temperature of the pressurized air is reduced, low-temperature air is formed. The low-temperature air is sprayed outward from the air jet port onto the tube sheet in the lower die seat, so that the tube sheet is cooled quickly; the tube sheet is cooled by the combination of coolant and low-temperature air, so that the tube sheet is cooled quickly and evenly.

[0016] 2. Filtering and processing of molten metal to prevent clogging of casting equipment. The boss pushes the contacting filter to bend toward the inner wall of the processing box. As the boss rotates, the boss does not contact the previous filter. At this time, the non-contacting filter gradually bends to the side away from the processing box under its own elastic force. The molten metal pushes the boss to rotate, causing the filter to bend back and forth, thereby achieving vibration of the filter, so that the molten metal can be filtered smoothly through the filter, preventing impurities from clogging the filter and casting equipment, and ensuring the filtering effect of the filter.

[0017] 3. Heat recovery from the tube sheet reduces the energy consumption of the casting device. The Seebeck effect generates current between the hot end and the cold end and transmits it to the control system. The control system first detects the current and uses it to cool the refrigeration plate after voltage transformation and rectification to reduce the energy consumption of the casting device.

[0018] 4. The molten metal is shaken to make the molten metal more evenly distributed in the upper die seat and the lower die seat. The control system drives the rotating frame to swing back and forth through the rotating motor, and the rotating frame drives the molten metal between the upper die seat and the lower die seat to shake, so that the molten metal is more evenly distributed in the upper die seat and the lower die seat.

[0023] The processing box 17 is hollow inside and is arranged outside the rotating frame 12. The two sides of the processing box 17 are respectively connected with a liquid inlet pipe 178 and a liquid outlet pipe 179. The liquid inlet pipe 178 is connected to the liquid supply system, and the liquid outlet pipe 179 is connected to the pouring port 152. A fixed shaft 171 is arranged inside the processing box 17. A first fixed plate 172 is arranged on the fixed shaft 171. The first fixed plate 172 is located on one side of the liquid inlet pipe 178.

[0024] The cooling box 16 is hollow inside and is arranged on the rotating frame 12. A transverse plate 161 is arranged in the cooling box 16. An air intake chamber is formed between one side of the transverse plate 161 and the cooling box 16. A plurality of longitudinal plates 162 are arranged between the other side of the transverse plate 161 and the cooling box 16. A plurality of cooling pipes 166 are arranged, and the plurality of cooling pipes 166 are respectively arranged in the plurality of longitudinal plates 162. The air intake chamber is connected to the outlet of the vacuum pump through a pipeline. The inlet of the vacuum pump (not shown in the figure) is connected to the external air.

A plurality of air jets 164 are arranged on the cooling box 16 facing the connecting port 163. The plurality of air jets 164 face the tube plate in the lower mold base 15.

[0025] An eardrum 19 is provided on the opposite side of two adjacent longitudinal plates 162. The eardrum 19 is made of flexible material and has a plurality of folds. A bimetallic strip 191 is provided on the longitudinal plate 162 inside the eardrum 19. One end of the bimetallic strip 191 is provided on the longitudinal plate 162, and the other end of the bimetallic strip 191 abuts against the middle of the eardrum 19. The bimetallic strip 191 is composed of two metal sheets with different expansion coefficients. The expansion coefficient of the metal sheet on one side of the eardrum 19 is smaller than the expansion coefficient of the metal sheet on the other side. Both metal sheets with different expansion coefficients are electrically connected to the control system. When cooling the tube sheet, the control system connects the bimetallic strip 191 to the circuit, and the current passes through two metal strips with different expansion coefficients and flows out to the control system. The two metal strips with different expansion coefficients heat up and bend at the same time. The metal strip with a larger expansion coefficient will bend toward the metal strip with a smaller expansion coefficient, thereby deforming the bimetallic strip 191 as a whole. The bimetallic strip 191 pushes the middle part of the tympanic membrane 19 to bend toward the side away from the longitudinal plate 162, so that the folds on the tympanic membrane 19 gradually unfold to increase the contact area between the pressurized air and the tympanic membrane 19 and improve the cooling effect. After the cooling end cools the longitudinal plate 162, the pressurized air is cooled through the tympanic membrane 19.

[0026] Multiple groups of cooling tubes 166 are all distributed in a plane thread pattern. The cooling tubes 166 with a plane thread pattern can extend the residence time of the coolant and improve the cooling effect of the coolant. The cooling tubes 166 are hollow inside, and coolant is arranged in the cooling tubes 166. A plurality of refrigeration plates 165 are arranged, and the plurality of refrigeration plates 165 are distributed along the inner wall of the cooling tube 166, and the plurality of refrigeration plates 165 are in contact with the coolant. A cooling chamber 153 is arranged in the lower mold base 15, and one end of the cooling tube 166 passes through the cooling box 16 through a pipeline and is connected to the inlet of the cooling chamber 153, and the other end of the cooling tube 166 passes through the cooling box 16 through a pipeline and is connected to the outlet of the cooling chamber 153. A circulating pump (not shown in the figure) is also connected in series to the pipeline connected to the cooling tube 166, and the circulating pump is installed on the rotating frame 12.

[0027] A plurality of first temperature difference plates 141 are arranged on the upper mold base 14, and a plurality of second temperature difference plates 121 are arranged on the rotating frame 12, and the plurality of first temperature difference plates 141 and the plurality of second temperature difference plates 121 correspond to each other one by one; the first temperature difference plate 141, the second temperature difference plate 121 and the refrigeration plate 165 are all provided with metal plates and semiconductors of two different materials, one end of the semiconductors of the two different materials are connected to the metal plate, the two semiconductors on the first temperature difference plate 141 and the two semiconductors on the second temperature difference plate 121 are connected by wires, one of which is connected to the control system, and the two semiconductors on the refrigeration plate 165 are electrically connected to the control system through wires.

[0028] Working principle: the staff presses the start button on the control panel 1, the casting device starts, the control system drives the upper die seat 14 to move downward through the longitudinal electric cylinder 13, so that the upper die seat 14, the lower die seat 15 and the lower cavity 151 cooperate to cast the tube plate, and the molten metal is transported to the liquid inlet pipe 178 through the liquid supply system. The high-temperature molten metal enters the processing box 17 through the liquid inlet pipe 178. After the high-temperature molten metal passes through the filter screen 174, it pushes the fan blade 176 to rotate. The fan blade 176 drives the boss to rotate through the rotating plate 175, and the convex The boss pushes the filter 174 in contact with the inner wall of the processing box 17 to bend. After that, as the boss rotates, the boss no longer contacts the previous filter 174. At this time, the filter 174 that is not in contact gradually bends to the side away from the processing box 17 under the action of its own elastic force. The molten metal pushes the boss to rotate, causing the filter 174 to bend back and forth, thereby realizing the vibration of the filter 174, so that the molten metal can be filtered smoothly through the filter 174, preventing impurities from clogging the filter 174, and ensuring the filtering effect of the filter 174.

[0029] The molten metal filtered by the filter screen 174 is transported from the liquid outlet pipe 179 to the upper die seat 14 and the lower die seat 15. The liquid supply system feeds back the flow data of the molten metal to the control system. The control system drives the rotating frame 12 to swing back and forth through the rotating motor 18. The rotating frame 12 drives the molten metal between the upper die seat 14 and the lower die seat 15 to swing back and forth, so that the molten metal is more evenly distributed in the upper die seat 14 and the lower die seat 15. The rotating motor 18 stops working after working for a set time, and the molten metal is in a static state. At this time, the upper die seat 14, the lower die seat 15 and the lower cavity 151 cooperate to realize the casting of the tube sheet.

[0030] After the tube sheet is cast to the set time, the control system connects the two semiconductors on the first temperature difference plate 141 and the second temperature difference plate 121 to the circuit. The metal plate and the two semiconductors on the first temperature difference plate 141 are the hot end of the Seebeck effect, and the metal plate and the two semiconductors on the second temperature difference plate 121 are the cold end of the Seebeck effect. Since the hot end is in direct contact with the cast tube sheet, and the cold end is in contact with the external air, the temperature of the hot end is higher than that of the cold end. Current is generated between the hot end and the cold end through the Seebeck effect and transmitted to the control system. The control system first detects the current, and then uses it for cooling the refrigeration plate 165 after processing such as voltage transformation and rectification. The refrigeration plate 165 can also be directly cooled by the control system; When the current generated by the Seebeck effect is less than the set current, the control system disconnects the two semiconductors on the first temperature difference plate 141 and the second temperature difference plate 121 from the control system, and drives the upper mold base 14 to move upward through the longitudinal electric cylinder 13 to facilitate cooling of the tube sheet.

[0031] When the longitudinal electric cylinder 13 drives the upper die seat 14 to move to the uppermost side, the encoder in the longitudinal electric cylinder 13 feeds back the displacement data of the upper die seat 14 to the control system, and the control system connects the two semiconductors on the refrigeration plate 165 to the circuit. The metal plate and the two semiconductors on the refrigeration plate 165 are the refrigeration ends of the Peltier effect. The cooling end cools the coolant in the cooling tube 166, and the cooling end cools the longitudinal plate 162 through the cooling tube 166 at the same time. The cooled coolant is drawn into the cooling chamber 153 by a circulation pump, and the tube sheet after casting is cooled by the cooling chamber 153. The temperature of the coolant in the cooling chamber 153 increases after heat exchange with the tube sheet. After the temperature increases, the coolant enters the cooling tube 166 again to cool down, forming a circulation of the coolant. When the tube sheet is cooled by the coolant, the control system pressurizes the external air through the vacuum pump and delivers it to the air intake chamber. The pressurized air contacts the tympanic membrane 19 on the longitudinal plate 162 through the connecting port 163. Since the longitudinal plate 162 is cooled by the refrigeration end, the longitudinal plate 162 reduces the temperature of the pressurized air through the tympanic membrane 19. After the temperature of the pressurized air is reduced, low-temperature air is formed. The low-temperature air is sprayed outward from the air jet 164 onto the tube sheet in the lower mold base 15 to quickly cool the tube sheet. The tube sheet is cooled by the combination of the coolant and the low-temperature air, so that the tube sheet is cooled quickly and evenly. After that, the staff takes out the cooled tube sheet for further processing.

[0032] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
