Description

Technical Field

[0001] The present invention relates to the technical field of non-standard storage tank production equipment, and specifically discloses a heat preservation conveying device and method for outer ring parts in the production of non-standard storage tanks. Background Art

[0002] Non-standard storage tanks are indispensable auxiliary components in new energy vehicles and can be widely involved in various modular technologies such as battery thermal management, energy storage, and system integration. The outer ring parts of non-standard storage tanks are customized annular or ring-shaped structural components installed around the outer wall of the tank. Such components usually include saddle supports, strengthening rings, connection sealing devices, and protective accessories, etc.; the saddle support is a structural support component that is responsible for evenly transferring the storage tank load to the foundation, and multi-point supports or special-shaped structures are often used in non-standard designs to adapt to special sizes or complex installation environments; the strengthening ring enhances the compressive and seismic resistance of the tank body through annular rib plates or stiffeners, especially suitable for high-pressure or large-capacity storage tanks; the connection sealing components are customized components such as flange rings to ensure the connection tightness between accessories such as pipelines and valves and non-standard storage tanks; the protective outer ring parts are auxiliary structures that mainly facilitate later maintenance and repair.

[0003] During the production process of non-standard storage tanks, it is necessary to pre-produce the main part of the tank body and place it in the processing platform to assemble the outer ring parts of the non-standard storage tank. Most of the outer ring parts of non-standard storage tanks have an interference fit with the non-standard storage tank. The radial pressing force generated by the interference fit can significantly improve the anti-deformation ability of the non-standard storage tank in high-pressure, vibration, or temperature fluctuation environments, preventing loosening or displacement caused by external loads or thermal expansion and contraction. Most outer ring parts carry high temperatures during assembly and can achieve the purpose of diameter reduction after cooling to room temperature, so as to effectively cooperate with mechanical assembly tools for interference mechanical biting of non-standard storage tanks.

[0004] At present, most of the outer ring parts of non-standard storage tanks are transported at normal temperature for transfer; the prior art with the publication number of CN119408890A discloses a modular high-speed roller conveyor line and its working method. This prior art is provided with a matching structure of a rotating shaft and rollers, and the distance between the roller bodies at both ends of the rotating shaft is changed through an adjusting component, so as to continuously transport the material. When the above prior art transports the outer ring parts of non-standard storage tanks, since the environment where the outer ring parts are located is at normal temperature, there is a large difference between this temperature and its surface temperature, and the surface temperature of the outer ring parts will drop sharply in a short time. Therefore, it is necessary for the operators to heat-treat them before the later installation. In the actual production process of the above prior art, the lack of temperature control in the normal temperature environment may lead to the deterioration of material properties. Especially for special alloys or highly sensitive materials, lattice structure changes are likely to occur under temperature difference fluctuations, resulting in a decrease in toughness, an increase in stress corrosion, or local deformation, directly affecting their mechanical strength and corrosion resistance; secondly, if the outer ring parts are heat-treated, it will not only increase the overall production time of the non-standard storage tank, but also occupy production equipment and human resources, driving up the invisible cost of non-standard storage tank production. Summary of the Invention

[0005] Aiming at the problems that in the production process of non-standard storage tanks, due to the normal temperature transportation of the outer ring parts, the mechanical strength of the outer ring parts is reduced and the invisible cost of non-standard storage tanks is relatively high, the present invention provides an outer ring part heat preservation conveying device and method for non-standard storage tank production.

The transmission wheel and the runner are connected by a belt drive. A clamping block is fixedly connected to the surface of the belt. The clamping block is fixedly connected to the receiving frame.

[0010] Preferably, a plurality of third motors are fixedly installed on the outer side of the carrier. The output shaft of the third motor is in driving cooperation with the roller. A plurality of stabilizing plates are fixedly installed on both carrier frames. The stabilizing plates are all arranged inside the outer cover.

[0011] Preferably, a plurality of second openings for the ventilation pipe to pass through are formed in the outer side end face of the receiving frame. A buffer gasket is fixedly sleeved on the outer wall of the ventilation pipe. The buffer gasket is fixedly connected to the receiving frame. The ventilation pipe is fixedly composed of multiple right-angle elbows. A stabilizing block is fixedly sleeved at the bending part of the ventilation pipe. The stabilizing block is arranged above the vertical plate. A hydraulic rod is installed at the top of the vertical plate. The end of the hydraulic rod is fixedly connected to the stabilizing block.

[0012] Preferably, the upper part of the outer cover is of a square box structure, and a cavity facilitating the passage of hot air flow is arranged inside the square box structure. At the front and rear ends of the lower part of the outer cover, a feed inlet and a discharge outlet for the outer ring part of the non-standard storage tank to enter and exit are respectively arranged. The first ventilation hole and the second ventilation hole are respectively arranged inside the feed inlet and the discharge outlet. Plungers are fixedly installed in both the first ventilation hole and the second ventilation hole, and the plungers are slidably matched with the outer wall of the ventilation pipe.

[0013] Preferably, both the first guide plate and the second guide plate are obliquely arranged.

A plurality of uniformly distributed guide holes are formed in the first guide plate and the second guide plate, and the guide holes are arranged below the first ventilation hole and the second ventilation hole.

[0014] Preferably, one end inside the first guide plate and the second guide plate is provided with a bending part. The outer end face of the bending part is fixedly connected to the first guide plate and the second guide plate. The inner end face of the bending part is a flat straight face and is vertically upward. A guide groove is arranged inside the bending part, and the guide groove is used to guide the hot air flow near the inner end of the first guide plate and the second guide plate to the upper part of the cavity of the outer cover.

[0015] On the other hand, the present invention also provides a method for heat-insulating transportation of the outer ring part for the production of non-standard storage tanks. The method includes: S1: The outer ring part of the non-standard storage tank is placed on the roller from the front end of the outer cover. The placement time is 10S, and the time interval between two adjacent outer ring parts of the non-standard storage tank is 6S. The roller enters the outer cover with the outer ring part of the non-standard storage tank from the feed inlet, and the outer ring part of the non-standard storage tank moves to the lower part of the first guide plate with the roller, and the roller stops moving. S2: Start the electric hot air blower. The hot air flow sequentially passes through the air supply cylinder and the ventilation pipe and then flows into the upper part of the first guide plate. Most of the hot air flow can be dispersed and covered on the surface of the outer ring part of the non-standard storage tank through the guide holes of the first guide plate. The hot air flow performs a primary heating and heat-insulating treatment on the outer ring part of the non-standard storage tank, and a small part of the hot air flow gathers in the upper part of the cavity of the outer cover after passing through the bending part. S3: Turn off the electric hot air blower, start the second motor. Under the driving action of the belt and the clamping block, the receiving frame slides vertically upward along the second guide rail, so that the ventilation pipe moves vertically upward, and the air outlet end of the ventilation pipe is separated from the plunger at the first ventilation hole. The roller transports the outer ring part of the non-standard storage tank to the lower part of the second guide plate. Under the driving action of the lead screw and the load platform, the air outlet end of the ventilation pipe moves above the plunger at the second ventilation hole. S4: The roller stops moving. The outer ring part of the non-standard storage tank moves to the lower part of the second guide plate with the roller. The time interval for the outer ring part of the non-standard storage tank to move from the first guide plate to the second guide plate is greater than 60S. S5: Start the second motor, insert one end of the air outlet of the ventilation pipe into the interior of the outer cover through the plunger. After starting the electric hot air blower, the hot air flow passes through the diversion holes of the second diversion plate in sequence and is dispersed and covered on the surface of the non-standard storage tank outer ring part. The hot air flow conducts secondary heating and heat preservation treatment on the non-standard storage tank outer ring part. The temperature of the hot air flow for secondary heating and heat preservation is higher than that of the hot air flow for primary heating and heat preservation.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the cooperation structure of the guiding frame and the load platform, the present invention can horizontally move the electric hot air blower and the air supply cylinder. By setting the cooperation structure of the ventilation pipe and the receiving frame, the hot air flow can be delivered into the outer cover in two times. By setting the first diversion plate and the second diversion plate in the outer cover, the hot air flow can be dispersed into multiple air columns with relatively average impact force, so that the hot air flow contacts the surface of the non-standard storage tank outer ring part on the roller, thereby ensuring that the surface temperature of the outer ring part meets the production and installation requirements of the non-standard storage tank. It can be seen that the present invention does not require a large amount of electricity as an energy support, not only optimizes the process flow, effectively reduces the production energy consumption of the overall conveying device, reduces the invisible production cost, but also effectively avoids reducing the mechanical strength of the outer ring part due to temperature loss and ensures the production quality of the non-standard storage tank; 2. By designing the ventilation pipe as a combined structure fixed by multiple sections of right-angle elbows, the present invention can fully cooperate with the receiving frame. On the one hand, it is convenient for the receiving frame to drive the ventilation pipe to move vertically. On the other hand, it is convenient for the ventilation pipe to enter and exit the first ventilation hole and the second ventilation hole, so as to ensure that the hot air flow generated by the electric hot air blower is delivered into the interior of the outer cover. By setting the buffer gasket and the stabilizing block, the stability of the ventilation pipe when the hot air flow passes through the ventilation pipe can be further improved, and the ventilation pipe can be effectively supported, so as to ensure the stability when the receiving frame slides along the second guide rail; 3. By setting the bending part on the inner side of the first diversion plate and the second diversion plate and setting the diversion groove in the bending part, the remaining hot air flow after passing through the first ventilation hole and the second ventilation hole can flow into the diversion groove. Under the action of the diversion groove, it is guided to the upper part of the outer cover cavity and accumulates in the upper part of the outer cover cavity, so that the interior of the outer cover is filled with hot air flow. During the movement of the non-standard storage tank outer ring part in the outer cover, it can fully contact the hot air flow in the outer cover, so as to avoid the temperature loss of the non-standard storage tank outer ring part during transportation and ensure the functionality of the conveying device. Therefore, it has a very wide application prospect. Description of the Drawings

The limiting rod 47 is arranged above the roller 44.

[0020] The upper part of the cover 1 is a square box structure, which is formed by tightly connecting side plates and a box cover through a right-angle frame. A cavity is arranged inside the square box structure. Oblique plates arranged symmetrically with each other are installed on both sides of the square box structure. The top end of the oblique plate is fixedly connected to the bottom of the square box structure. A cross plate 15 is arranged outside the bottom end of the oblique plate.

The sliding part 19 is arranged inside the trough 18, and both sides of the sliding part 19 are slidably matched with the inner wall of the trough 18. A lead screw 20 is installed in the trough 18. The length of the lead screw 20 is the same as the length of the first guide rail 16. The sliding part 19 is sleeved on the outer wall of the lead screw 20. The lead screw 20 is arranged in parallel with the first guide rail 16. The end of the lead screw 20 is drivingly connected to a first motor 21. The body of the first motor 21 is firmly connected to the tabletop of the support platform 2. The output shaft of the first motor 21 is drivingly connected to the lead screw 20. By setting the cooperative driving structure of the first motor 21 and the lead screw 20, the sliding part 19 can drive the load platform 4 to perform linear displacement along the first guide rail 16, so as to realize the lateral movement of the load platform 4 inside the guide frame 3.

[0022] The load platform 4 is a frame structure with a hollow interior, and an end plate 22 is fixedly installed inside it.

An electric hot air blower 6 is fixedly installed at the air inlet of the air supply cylinder 5, and the air outlet of the electric hot air blower 6 is arranged inside the air supply cylinder 5. The casing of the electric hot air blower 6 is tightly connected to the inner wall at the air inlet of the air supply cylinder 5. The electric hot air blower 6 can suck external air into it, generate a hot air flow under the action of electric heating, and introduce the hot air flow into the inner cavity of the air supply cylinder 5 through the fan inside the electric hot air blower 6. A rubber block 23 is fixedly installed at the air outlet of the air supply cylinder 5. The shape of the rubber block 23 is adapted to the cross-sectional shape of the air outlet, and the rubber block 23 is in interference fit with the air outlet of the air supply cylinder 5, so that the outer wall of the rubber block 23 closely adheres to the inside of the air outlet of the air supply cylinder 5, thereby fixedly installing the rubber block 23 at the air outlet of the air supply cylinder 5.

The buffer gasket 33 is tightly connected to the receiving frame 9. By providing the buffer gasket 33, a buffer structure can be set for the receiving frame 9 and the ventilation pipe 8, thereby avoiding damage to the structure of the receiving frame 9 caused by the vibration of the ventilation pipe 8.

[0024] A vertical plate 10 is fixedly installed on the top of the guide frame 3, and a second guide rail 25 is fixedly installed on the outer end surface of the vertical plate 10. The second guide rail 25 is arranged above the first guide rail 16 and perpendicular to the first guide rail 16.

A clamping block 31 is fixedly connected to the surface of the belt 30, and the clamping block 31 is tightly connected to the receiving frame 9. By setting the matching structure of the transmission wheel 28, the belt 30 and the clamping block 31, the second motor 27 can drive the belt 30 to rotate, thereby driving the receiving frame 9 to slide linearly along the second guide rail 25, so as to adjust the arrangement height of the receiving frame 9.

[0025] Among them, a stabilizing block 34 is fixedly mounted at the bending connection between the horizontal straight pipe portion of the first right-angle bend pipe of the ventilation pipe 8 and the vertical pipe portion of the second right-angle bend pipe, and the stabilizing block 34 is arranged above the vertical plate 10. A hydraulic rod 35 is installed on the top of the vertical plate 10. The shell of the hydraulic rod 35 is tightly connected to the top end surface of the vertical plate 10, and the end of the hydraulic rod 35 is tightly connected to the stabilizing block 34. By setting the stabilizing block 34, the connection between the first right-angle bend pipe of the ventilation pipe 8 and the second right-angle bend pipe can be made more stable, thereby ensuring the stability of the overall structure of the ventilation pipe 8; by setting the hydraulic rod 35, the hydraulic rod 35 can effectively support the stabilizing block 34 and the ventilation pipe 8, thereby alleviating the connection stress between the second slider 26 and the receiving frame 9, and further ensuring the stability of the receiving frame 9 when sliding along the second guide rail 25.

[0026] A plurality of first ventilation holes 11 are provided at the front end of the top of the outer cover 1, and a plurality of second ventilation holes 12 are provided at the rear end of the top of the outer cover 1.

The plunger 38 can play a role of dynamic and static sealing. When the ventilation pipe 8 is not inserted into the plunger 38, the baffle in the plunger 38 can close the inner cavity of the plunger 38. When the ventilation pipe 8 is inserted into the plunger 38, the ventilation pipe 8 abuts against the baffle in the plunger 38 to form a smooth channel, so as to facilitate the ventilation pipe to enter and exit the first ventilation holes 11 and the second ventilation holes 12. A first guide plate 13 and a second guide plate 14 which are fixedly connected to the inner wall of the outer cover 1 are respectively arranged below the first ventilation holes 11 and the second ventilation holes 12. The first guide plate 13 and the second guide plate 14 are both obliquely arranged. The arrangement height of the inner ends of the first guide plate 13 and the second guide plate 14 is lower than that of the outer ends. A plurality of uniformly distributed guide holes 39 are formed in the first guide plate 13 and the second guide plate 14. The guide holes 39 are arranged below the first ventilation holes 11 and the second ventilation holes 12. The hot air flow in the ventilation pipe 8 can directly impact on the first guide plate 13 and the second guide plate 14. Under the dispersion action of the first ventilation holes 11 and the second ventilation holes 12, the single air flow column with strong impact is dispersed into a plurality of air flow columns with general impact. The air flow columns generated by the first ventilation holes 11 and the second ventilation holes 12 can flow to the surface of the roller 44.

[0027] Wherein, a bending portion 40 is provided at the inner ends of the first guide plate 13 and the second guide plate 14. The outer end faces of the bending portion 40 close to the feed port 36 and the discharge port 37 are fixedly connected to the first guide plate 13 and the second guide plate 14. The inner end face of the bending portion 40 is a flat straight face and is vertically upward. A guide groove 41 is arranged in the bending portion 40. The remaining hot air flow after passing through the first ventilation holes 11 and the second ventilation holes 12 can flow into the guide groove 41. The guide groove 41 is used to guide the hot air flow near the inner ends of the first guide plate 13 and the second guide plate 14 to the upper part of the cavity of the outer cover 1 and gather in the upper part of the cavity of the outer cover 1, so that the inside of the outer cover 1 is filled with hot air flow.

[0028] In the above, the embodiments of an outer ring part heat preservation conveying device for non-standard storage tank production are described in detail. Based on the outer ring part heat preservation conveying device described in the above embodiments, the embodiments of the present invention also provide a heat preservation conveying method corresponding to the device, including the following steps: S1: The non-standard storage tank outer ring is placed on the roller 44 from the front end of the outer cover 1. The placement time is 10S, and the time interval between adjacent non-standard storage tank outer rings is 60S. After starting the third motor 45, the roller 44 feeds the non-standard storage tank outer ring into the outer cover 1 through the feed port 36. The non-standard storage tank outer ring moves with the roller 44 to the lower part of the first deflector 13, and then the roller 44 stops moving; S2: Start the electric hot air blower 6. The electric hot air blower 6 sucks external air into the interior and generates a hot air flow under the action of electric heating. The hot air flow successively passes through the air supply cylinder 5 and the ventilation pipe 8 and then flows into the upper part of the first deflector 13. Most of the hot air flow can be dispersed and covered on the surface of the non-standard storage tank outer ring through the diversion holes 39 of the first deflector 13. The hot air flow performs a primary heating and heat preservation treatment on the non-standard storage tank outer ring. The third motor 45 adjacent to the lower side of the first deflector 13 reduces the output frequency, so that the non-standard storage tank outer ring moves forward slowly. A small part of the hot air flow gathers in the upper part of the cavity of the outer cover 1 after passing through the bending part 40 and gradually spreads into the interior space of the outer cover 1; S3: Turn off the electric hot air blower 6 and start the second motor 27. Under the driving action of the belt 30 and the clamping block 31, the receiving frame 9 slides vertically upward along the second guide rail 25, making the ventilation pipe 8 move vertically upward, so that the air outlet end of the ventilation pipe 8 disengages from the plunger 38 at the first ventilation hole 11. The third motor 45 adjacent to the lower side of the first deflector 13 increases the output frequency, so that the roller 44 transports the non-standard storage tank outer ring to the lower part of the second deflector 14. During this period, the hot air in the interior space of the outer cover 1 can contact the surface of the non-standard storage tank outer ring, avoiding the loss of temperature of the non-standard storage tank outer ring during transportation. Under the driving action of the lead screw 20 and the load platform 4, the air outlet end of the ventilation pipe 8 moves above the plunger 38 at the second ventilation hole 12; S4: The roller 44 stops moving. The non-standard storage tank outer ring moves with the roller 44 to the lower part of the second deflector 14. The time interval for the non-standard storage tank outer ring to move from the first deflector 13 to the second deflector 14 is greater than 60S, thus providing sufficient time for the next placement of the non-standard storage tank outer ring; S5: Start the second motor 27, extend the air outlet end of the ventilation pipe 8 into the interior of the outer cover 1 through the plunger 38. After starting the electric hot air blower 6, the hot air flow successively passes through the diversion holes 39 of the second deflector 14 and is dispersed and covered on the surface of the non-standard storage tank outer ring. The hot air flow performs a secondary heating and heat preservation treatment on the non-standard storage tank outer ring. The temperature of the hot air flow for the secondary heating and heat preservation is higher than that of the hot air flow for the primary heating and heat preservation, thereby slowing down the loss time of the surface temperature of the non-standard storage tank outer ring after it disengages from the conveying device. The roller 44 continues to rotate, and thus transports the non-standard storage tank outer ring to the product processing and manufacturing area of the non-standard storage tank.

[0029] The working principle of the present invention is: During the production operation of non-standard storage tanks, operators can separately place the outer ring parts of non-standard storage tanks on the rotating roller 44. When the rotating roller 44 conveys the outer ring parts of non-standard storage tanks, it needs to pass through the outer cover 1. During the process of the outer ring parts of non-standard storage tanks passing through the outer cover 1, they will make two stops at the front end and the rear end of the outer cover 1. During the stop time, the electric heating blower 6 can input hot air flow into the interior of the outer cover 1 through the ventilation pipe 8. Under the dispersion effect of the first guide plate 13 and the second guide plate 14, the hot air flow is gently swept to the surface of the outer ring parts of non-standard storage tanks. On the one hand, using a single electric heating blower 6 can reduce production costs and production energy consumption, and control the temperature of the two heating and heat preservation processes, so that the temperature of the secondary heating and heat preservation is higher than that of the primary heating and heat preservation, ensuring that the outer ring parts can be installed smoothly. On the other hand, dispersing the hot air flow can ensure the uniformity of the temperature inside the outer cover 1, avoid excessive temperature loss of the outer ring parts of non-standard storage tanks in the outer cover 1, and ensure the functionality of the conveying device.

Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
