Description

Technical Field

[0001] The utility model relates to a steam boiler, in particular to a steam boiler used in a fermented black bean workshop, and belongs to the technical field of fermented black bean processing and production equipment. Background Art

[0002] During the production of fermented black beans, soybeans need to be steamed after being soaked. However, steaming at room temperature has low thermal efficiency, takes a long time, and has raw core inside, so high-pressure steam is usually used for steaming. Soybeans steamed with high-temperature steam can quickly destroy the molecular structure inside the soybeans, denature the protein and make it easy to hydrolyze, so that the starch reaches the gelatinization degree, and at the same time plays a sterilizing role. Therefore, fermented black bean workshops often need steam boilers to generate steam for soybean processing. In existing steam boilers, a burner is used to form a flame to heat the water in the boiler to form steam; in order to achieve energy saving, the flue gas in the combustion is usually introduced into the boiler so that the heat carried by the flue gas is exchanged with water to accelerate the evaporation of water. However, if the flue gas passes through too fast and the heat exchange is not sufficient, the heat carried by the flue gas will be wasted. In order to avoid the above problems, the prior art usually adopts a method of extending the length of the smoke pipe to extend the heat exchange time, but this method will form a complex smoke pipe structure in the boiler, occupy the water storage space of the boiler, reduce the amount of steam generated, and increase the frequency of use. Therefore, further improvement is needed. Utility Model Content

[0003] The utility model aims to solve the above shortcomings and provide a steam boiler for a fermented black bean workshop, which improves the utilization rate of the internal space of the boiler, improves the utilization rate of the heat of the flue gas, has a simple and reasonable structure, and can be adaptively adjusted.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A steam boiler for a fermented black bean workshop comprises a main body; a burner is arranged on one side of the main body; a smoke pipe is arranged in the main body, and a smoke chamber is arranged on the burner; the smoke pipe has a smoke inlet and a smoke outlet; a multi-channel lifting smoke exhaust component is arranged in the smoke chamber; the multi-channel lifting smoke exhaust component is provided with a first inlet and a second inlet connected to the smoke outlet; the multi-channel lifting smoke exhaust component is connected to a driving end; a temperature detection element is arranged in the smoke chamber.

[0006] Furthermore, the multi-channel lifting smoke exhaust assembly includes a lifting guide block; the first inlet and the second inlet are distributed vertically on the side of the lifting guide block; and the first channel and the second channel are arranged in the lifting guide block.

[0007] Furthermore, the first inlet is connected to the first channel; the first inlet and the smoke pipe have the same inner diameter; the second inlet is connected to the second channel; a flow limiting plug is provided in the second inlet; the first channel and the second channel are respectively connected to the vertical smoke exhaust pipe.

[0008] Furthermore, the flow limiting plug is conical; the side of the flow limiting plug close to the smoke outlet is the large end, and the side away from the smoke outlet is the small end; the flow limiting plug has a smoke channel with a trapezoidal cross-section; the width of the smoke channel gradually decreases from the smoke outlet side.

[0009] Furthermore, the temperature detection element is a temperature sensor; the temperature sensor is arranged on the upper surface of the lifting guide block; and a sliding mechanical seal is formed between the side of the lifting guide block and the inner wall of the smoke chamber.

[0010] Furthermore, the multi-channel lifting smoke exhaust assembly also includes a cylinder arranged in the lifting guide block; a cross bar is arranged in the smoke chamber; and the cross bar is located at the lower side of the lifting guide block.

[0011] Furthermore, a support block is arranged on the horizontal bar; the piston end of the cylinder abuts against the support block; and a smoke through hole is opened in the smoke chamber relative to the burner.

[0012] Furthermore, the cylinder and the temperature sensor are respectively connected to the controller.

[0013] The utility model has the following beneficial effects: without extending the length of the smoke pipe, the temperature of the smoke after heat exchange in the boiler is detected by the temperature detection element; if the smoke temperature is high, it proves that the heat exchange between the smoke and water is not complete, then the second inlet in the multi-channel lifting smoke exhaust component is controlled to connect with the smoke outlet, and because the second inlet is provided with a flow limiting plug, the smoke passage time can be extended, thereby extending the time the smoke stays in the smoke pipe, which is conducive to more thorough heat exchange; if the detected smoke temperature is relatively low, the smoke outlet can be connected through the second inlet to discharge the smoke at a regular time. In this way, the multi-channel lifting smoke exhaust component only needs to be set in the existing smoke chamber, without the need to expand the boiler space additionally, and at the same time, the smoke pipe length can be reduced, and the internal space utilization of the boiler can be improved.

[0022] A steam boiler for a fermented black bean workshop comprises a main body 1; a burner 2 is arranged on one side of the main body 1; a smoke pipe 3 is arranged in the main body 1, and a smoke chamber 4 is arranged on the burner 2; the smoke pipe 3 has a smoke inlet 3.1 and a smoke outlet 3.2; a multi-channel lifting smoke exhaust component is arranged in the smoke chamber 4; a first inlet 5 and a second inlet 6 connected to the smoke outlet 3.2 are arranged on the multi-channel lifting smoke exhaust component; the multi-channel lifting smoke exhaust component is connected to a driving end; a temperature detection element is arranged in the smoke chamber 4.

[0023] Furthermore, the multi-channel lifting smoke exhaust assembly includes a lifting guide block 7; the first inlet 5 and the second inlet 6 are distributed vertically on the side of the lifting guide block 7; and the first channel 8 and the second channel 9 are arranged in the lifting guide block 7.

[0024] Furthermore, the first inlet 5 is connected to the first channel 8; the first inlet 5 and the smoke pipe 3 have the same inner diameter; the second inlet 6 is connected to the second channel 9; a flow limiting plug 10 is provided in the second inlet 6; the first channel 8 and the second channel 9 are respectively connected to the vertical smoke exhaust pipe 11.

[0025] When the smoke enters the first channel 8 through the first inlet 5 from the smoke outlet 3.2, the movement speed of the smoke does not change because the first inlet 5 and the smoke pipe 3 have the same inner diameter. This state is used when the smoke has a large temperature drop in the body 1 and a good heat exchange effect, and there is no need to change the movement speed of the smoke in the smoke pipe 3.

[0026] Furthermore, the flow limiting plug 10 is conical; the side of the flow limiting plug 10 close to the smoke outlet 3.2 is the large end, and the side away from the smoke outlet 3.2 is the small end; the flow limiting plug 10 has a smoke channel 10.1 with a trapezoidal cross-section; the width of the smoke channel 10.1 gradually decreases from the side of the smoke outlet 3.2.

[0027] Since there is only one smoke outlet 3.2, smoke in the smoke pipe 3 can only enter the smoke chamber 4 through the smoke outlet 3.2, and the difference is whether it enters through the first inlet 5 or the second inlet 6; when entering through the second inlet 6, the flow speed of the smoke will be reduced due to the presence of the flow limiting plug 10. The specific mode to be selected can be determined by the temperature detection element to judge the smoke temperature.

[0028] Furthermore, the temperature detection element is a temperature sensor 12 ; the temperature sensor 12 is arranged on the upper surface of the lifting guide block 7 ; a sliding mechanical seal is formed between the side of the lifting guide block 7 and the inner wall of the smoke chamber 4 .

[0029] Furthermore, the multi-channel lifting smoke exhaust assembly also includes a cylinder 13 arranged in the lifting guide block 7; a cross bar 14 is arranged in the smoke chamber 4; and the cross bar 14 is located at the lower side of the lifting guide block 7.

[0030] Furthermore, a support block is provided on the horizontal bar 14 ; the piston end of the cylinder 13 abuts against the support block; and a smoke through hole 15 is opened in the smoke chamber 4 relative to the burner 2 .

[0031] Furthermore, the cylinder and the temperature sensor 12 are connected to the controller respectively.

[0032] The temperature sensor 12 detects the temperature of the smoke discharged from the smoke pipe 3 in real time, and controls the connection between the first inlet or the second inlet and the smoke outlet 3.2 through the cylinder 13.

[0033] Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the utility model rather than limiting it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
