Plate evaporator for concentrating ferrous gluconate solution

Abstract

This utility model discloses a plate evaporator for concentrating ferrous gluconate solution, comprising an outer shell. A medium inlet and a feed port are fixedly installed at the top of the outer shell, and a discharge port and a medium outlet are fixedly installed at the bottom. Removable, staggered evaporation plates are installed inside. Transfer pipes are fixedly installed on both sides of each evaporation plate. Adjacent evaporation plates are connected via transfer pipes, and the two outermost evaporation plates are connected to the medium inlet and medium outlet via transfer pipes. Each pair of connected transfer pipes is equipped with a leak-proof mechanism. By incorporating a leak-proof mechanism inside the transfer pipes, when adjacent transfer pipes are disassembled, the push plate of the flow element no longer applies pressure to the sealing plug of the leak-proof component. At this time, the spring force in the leak-proof component causes the sealing plate and sealing plug to reset, tightly sealing the internal channel of the transfer pipe and preventing leakage of residual ferrous gluconate solution or heating medium from the pipe.

Description

Technical Field

[0001] This utility model belongs to the field of ferrous gluconate solution concentration technology, and particularly relates to a plate evaporator for ferrous gluconate solution concentration. Background Technology

[0002] Ferrous gluconate is a common organic iron supplement with high bioavailability and few side effects. In the pharmaceutical field, it can be used as a drug excipient to adjust the pH value of the drug, or as a laxative to promote defecation by increasing intestinal osmotic pressure.

[0003] When the connecting pipes between the evaporator plates are disassembled or reassembled, the internal liquid medium is prone to leaking out, which can easily affect other components of the evaporator and reduce the overall service life of the device. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] A plate evaporator for concentrating ferrous gluconate solution includes an outer shell. A medium inlet and a feed port are fixedly installed on the top of the outer shell, and a discharge port and a medium outlet are fixedly installed on the bottom. Removable and staggered evaporation plates are installed inside. Transfer pipes are fixedly installed on both sides of each evaporation plate. Adjacent evaporation plates are connected through transfer pipes. The two outermost evaporation plates are connected to the medium inlet and the medium outlet through transfer pipes. Each pair of connected transfer pipes is equipped with a leak-proof mechanism.

[0006] As a preferred embodiment of the above technical solution, a flange is fixedly installed on the outer side of the transfer pipe, two adjacent transfer pipes are connected by the flange, and a sealing ring is provided between the two adjacent transfer pipes.

[0007] As a preferred embodiment of the above technical solution, the leak-proof mechanism includes a flow element and a leak-proof element in the inner wall of the mounting base transfer pipe, wherein the flow element pushes the leak-proof element to keep the transfer pipe unobstructed.

[0008] As a preferred embodiment of the above technical solution, the flow component includes an annular fixing frame fixed in the inner wall of the transfer pipe, a connecting rod 1 fixedly connected to the inner wall of the annular fixing frame, a connecting rod 2 fixedly connected to one end of the connecting rod 1, and a push plate fixedly connected to the end of the connecting rod 2 near the other transfer pipe.

[0009] As a preferred embodiment of the above technical solution, the leak-proof component includes a hollow plate fixed in the inner wall of the transfer pipe, a piston rod movably sleeved on the inner ring of the hollow plate, an anti-detachment plate and a sealing plate fixedly connected to both ends of the piston rod respectively, a spring fixedly connected to one end of the sealing plate, the other end of the spring being fixedly connected to the hollow plate, and the push plate abutting against the sealing plug through the channel of the hollow plate.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model provides a leak-proof mechanism inside the transfer pipe. When adjacent transfer pipes are disassembled, the push plate of the flow part no longer applies a pushing force to the sealing plug of the leak-proof part. At this time, the elastic force of the spring in the leak-proof part will drive the sealing plate and sealing plug to reset, tightly sealing the internal channel of the transfer pipe and preventing leakage of residual ferrous gluconate solution or heating medium in the pipeline.

[0012] 2. The connecting pipes of this utility model are connected by flanges and fitted with sealing rings to form the first line of defense for sealing. At the same time, when the device is working normally and the connecting pipe is connected, the internal anti-leakage mechanism pushes the sealing plug with the push plate of the flow element to keep the channel open. The fit between the sealing plate and the inner wall of the connecting pipe can help enhance the sealing effect. The double sealing design greatly reduces the risk of medium leakage during normal operation, ensures that the medium flows along the predetermined path during the concentration of ferrous gluconate solution, and improves the evaporation efficiency and the stability of the device operation.

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] Example

[0019] like Figure 1 and Figure 2As shown, a plate evaporator for concentrating ferrous gluconate solution includes an outer shell 10. A medium inlet 11 and a feed inlet 12 are fixedly installed on the top of the outer shell 10, and a discharge outlet 13 and a medium outlet 14 are fixedly installed on the bottom. Removable and staggered evaporation plates 15 are installed inside. Transfer pipes 16 are fixedly installed on both sides of the evaporation plates 15. Two adjacent evaporation plates 15 are connected through the transfer pipes 16. The two outer evaporation plates 15 are connected to the medium inlet 11 and the medium outlet 14 through the transfer pipes 16. Each pair of connected transfer pipes 16 is equipped with a leak-proof mechanism.

[0020] It should be noted that the outer shell 10 serves as the basic frame, providing installation space for internal components and providing protection. The inlet 12 is used to input the ferrous gluconate solution to be concentrated, and the outlet 13 is used to output the concentrated solution. The medium inlet 11 and the medium outlet 14 are used to introduce and discharge heating media, such as steam, to provide heat for solution concentration. The evaporation plates 15 are the core components of the concentration process. Their staggered arrangement can increase the heat exchange area and improve the concentration efficiency. The transfer pipe 16 serves as a connecting channel to realize the connection between the evaporation plates 15 and between the evaporation plates 15 and the medium inlet and outlet, ensuring the circulation of the solution and the medium.

[0021] like Figure 1 As shown, a flange 17 is fixedly installed on the outer side of the transfer pipe 16, two adjacent transfer pipes 16 are connected by the flange 17, and a sealing ring 20 is provided between the two adjacent transfer pipes 16.

[0022] It should be noted that flange 17 achieves a stable connection between adjacent transfer pipes 16 through fasteners such as bolts, ensuring convenient disassembly and assembly. The sealing ring 20 fills the connection gap between the two transfer pipes 16, reducing the risk of leakage of solution or heating medium during normal operation and enhancing the sealing performance of the connection.

[0023] like Figure 1 As shown, the leak prevention mechanism includes a flow element 30 and a leak-proof element 40 in the inner wall of the mounting base adapter pipe 16. The flow element 30 pushes the leak-proof element 40 to keep the adapter pipe 16 unobstructed.

[0024] like Figure 2 As shown, the flow member 30 includes an annular fixing frame 31 fixed in the inner wall of the adapter pipe 16. A connecting rod 32 is fixedly connected to the inner wall of the annular fixing frame 31. A connecting rod 33 is fixedly connected to one end of the connecting rod 32. A push plate 34 is fixedly connected to the end of the connecting rod 33 near the other adapter pipe 16.

[0025] Specifically, the annular fixing frame 31 provides a fixed base for the entire flow component 30, ensuring that it does not shake with the flow of the medium within the transfer pipe 16. The connecting rod 1 32 and the connecting rod 2 33 serve as force transmission structures, stably supporting the push plate 34 on one side close to the adjacent transfer pipe 16. When the two transfer pipes 16 are connected, the push plate 34 can extend into the other transfer pipe 16 to push the sealing component of the leak-proof component 40, ensuring that the channel is unobstructed.

[0026] like Figure 2 As shown, the leak-proof component 40 includes a hollow plate 41 fixed in the inner wall of the adapter pipe 16. A piston rod 42 is movably sleeved on the inner ring of the hollow plate 41. An anti-detachment plate 43 and a sealing plate 44 are fixedly connected to both ends of the piston rod 42, respectively. A spring 45 is fixedly connected to one end of the sealing plate 44. The other end of the spring 45 is fixedly connected to the hollow plate 41. The push plate 34 passes through the channel of the hollow plate 41 and abuts against the sealing plug 46.

[0027] Specifically, when the adapter pipe 16 is connected, the push plate 34 passes through the hollow plate 41 channel and abuts against the sealing plug 46, compressing the spring 45 to separate the sealing plate 44 from the inner wall of the adapter pipe 16, keeping the channel unobstructed; when the adapter pipe 16 is disassembled, the push plate 34 disengages from the sealing plug 46, the spring 45 returns to its original position, pushing the sealing plate 44 to fit tightly against the inner wall of the adapter pipe 16, the sealing plug 46 blocks the channel to prevent residual liquid leakage, the hollow plate 41 provides a guide for the piston rod 42, and the anti-detachment plate 43 prevents the piston rod 42 from coming out of the hollow plate 41, ensuring the long-term stable operation of the leak-proof component 40.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
