Description

Technical Field

[0001] The utility model relates to the technical field of steam heat recovery, in particular to a steam heat recovery system. Background Technique

[0002] Milk is a common and widely used food that can provide rich nutrients and healthy energy. The production process of milk is a complex process that requires multiple steps and links. The steps mainly include raw material collection and storage, raw material processing, concentration processing, blending and additives, and filling and detection.

[0003] At present, during the concentration process of milk, a cooking pot is needed to steam the milk to remove the moisture in the milk in order to reduce the volume and extend the service life. During the process of steaming milk in the cooking pot, due to the generation of a large amount of steam, in order to avoid waste of thermal resources, when designing the cooking pot for boiling milk, a heat-absorbing water pipe for absorbing heat is also horizontally placed in the pipe for discharging water vapor, so as to transfer the heat in the steam to the water in the water pipe to become hot water, which is convenient for the factory to use to achieve the purpose of saving energy. However, during the process of steaming milk, when the steam contacts the heat-absorbing water pipe, a large amount of condensed water droplets will condense on the outer wall of the heat-absorbing water pipe. Some of the condensed water droplets will directly fall into the lower cooking pot, and some of the condensed water droplets will fall into the cooking pot or the cooker along the pipe, which will not only affect the hygienic quality of the milk, but also affect the cooker heating the cooking pot. Therefore, we propose a steam heat recovery system to solve the above problems. Content of the Utility Model

A steam discharge cylinder is fixedly connected to the inner top of the fixing frame. An inverted conical condensation cylinder is fixedly connected to the bottom of the steam discharge cylinder. A plurality of heat recovery metal pipes are fixedly connected to the inner side wall of the steam discharge cylinder and are inclined. The ends of two adjacent heat recovery metal pipes in the same plane are connected by a connecting pipe;

[0007] Water inlet pipes are fixedly connected to the ends of the two lowermost heat recovery metal pipes, water outlet pipes are fixedly connected to the ends of the two uppermost heat recovery metal pipes, the tops of the two water outlet pipes are fixedly connected to the same drain pipe. A conical smooth sleeve block in contact with the inner wall of the steam discharge cylinder is fixedly sleeved on the outer side wall of the heat recovery metal pipe. A liquid discharge annular half pipe is fixedly connected to the top of the support table, and a liquid discharge pipe communicating with the liquid discharge annular half pipe is fixedly connected to the bottom of the support table.

[0008] Preferably, both the exhaust chimney and the inverted conical condensation cylinder are located directly above the cooking stove.

[0009] Preferably, multiple heat recovery metal tubes in the same plane are arranged parallel to each other, and the distance between two adjacent heat recovery metal tubes in the same plane is the same.

[0010] Preferably, the conical smooth sleeve block is located on the inclined bottom of the heat recovery metal tube.

[0011] Preferably, the two connecting pipes at the ends of the heat recovery metal tube are arranged centrosymmetrically.

[0012] The beneficial effects of the present utility model are as follows:

[0013] Under the interaction of the support platform, the cooking stove, the heat recovery metal tube, the drain pipe, the conical smooth sleeve block, the liquid drainage annular half-tube and the liquid drainage pipe, the inclined heat recovery metal tube is more conducive to the condensed water flowing along the heat recovery metal tube to the inner wall of the exhaust chimney, and then the condensed water drips from the inner wall of the inverted conical condensation cylinder onto the liquid drainage annular half-tube for collection and utilization, thus avoiding the condensed water from dripping onto the cooking stove, making the milk processing process more environmentally friendly.

Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Refer to Figures 1-3, A steam heat recovery system, including a support platform 1, a cooking stove top 2 fixedly arranged on the top of the support platform 1, and a fixing frame 3. A steam exhaust cylinder 4 is fixedly connected to the inner top of the fixing frame 3. A conical condensation cylinder 5 is fixedly connected to the bottom of the steam exhaust cylinder 4. Both the steam exhaust cylinder 4 and the conical condensation cylinder 5 are located directly above the cooking stove top 2. The position of the conical condensation cylinder 5 is as Figure 1 shown. The inner wall of the conical condensation cylinder 5 is smooth, facilitating the flow-down of condensed water.

[0020] A plurality of heat recovery metal tubes 6 which are inclined are fixedly connected to the inner side wall of the steam exhaust cylinder 4. The material used for the heat recovery metal tubes 6 has good thermal conductivity, facilitating the recovery of heat in the steam. Multiple heat recovery metal tubes 6 in the same plane are arranged parallel to each other. The distance between adjacent two heat recovery metal tubes 6 in the same plane is the same. The ends of adjacent two heat recovery metal tubes 6 in the same plane are connected by a connecting pipe 7. The two connecting pipes 7 located at the ends of the heat recovery metal tubes 6 are arranged centrosymmetrically. The positions of the multiple connecting pipes 7 are as Figure 1 shown.

[0021] Water inlet pipes 8 are fixedly connected to the ends of the two heat recovery metal tubes 6 at the bottommost. Water outlet pipes 9 are fixedly connected to the ends of the two heat recovery metal tubes 6 at the uppermost. The tops of the two water outlet pipes 9 are fixedly connected to the same drain pipe 10. A conical smooth sleeve block 11 which contacts the inner wall of the steam exhaust cylinder 4 is fixedly sleeved on the outer side wall of the heat recovery metal tube 6.

[0022] The purpose of setting the conical smooth sleeve block 11 is to make it more convenient for the condensed water to flow onto the inner wall of the conical condensation cylinder 5. The conical smooth sleeve block 11 is located at the inclined bottom of the heat recovery metal tube 6. A liquid discharge annular half-tube 12 is fixedly connected to the top of the support platform 1. A liquid discharge pipe 13 which is communicated with the liquid discharge annular half-tube 12 is fixedly connected to the bottom of the support platform 1.

[0023] The functional principle of the present utility model can be elaborated through the following operation method: After the cooking stove top 2 is started, a large amount of steam will overflow from the top of the cooking stove top 2. A large amount of steam will pass through the multiple heat recovery metal tubes 6. By injecting the clear water to be heated into the water inlet pipe 8, the clear water will sequentially enter the heat recovery metal tubes 6 on the upper layer from the heat recovery metal tubes 6 at the bottommost through the connecting pipes 7, and so on, until finally the clear water enters the water outlet pipe 9 from the heat recovery metal tubes 6 at the uppermost and is finally discharged from the drain pipe 10.

[0024] When the clear water passes through the multiple heat recovery metal tubes 6, the steam heats the heat recovery metal tubes 6, enabling the heat to be transferred to the clear water inside the heat recovery metal tubes 6, making the clear water absorb heat and turn into hot water. As the clear water passes through the multiple heat recovery metal tubes 6, it can be heated time and time again. The hot clear water is finally discharged from the drain pipe 10.

[0025] When fresh water passes through the heat recovery metal pipe 6, steam passing through the heat recovery metal pipe 6 will condense on the outer wall of the heat recovery metal pipe 6. Due to gravity, the condensed water will flow down along the inclined heat recovery metal pipe 6. The condensed water flows into the inner wall of the inverted conical condensation cylinder 5 through the conical smooth sleeve block 11, and finally the condensed water drips from the bottom of the inverted conical condensation cylinder 5. The condensed water droplets will drip on the liquid discharge annular half pipe 12, and finally the condensed water is discharged from the liquid discharge pipe 13.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
