Description

Technical Field

[0001] This utility model relates to the field of steam generating equipment, and in particular to a steam generator sewage discharge device. Background Technology

[0002] A steam generator is a device that heats water using a heat source to vaporize it. The steam produced can be used for disinfection, sterilization, humidification, deodorization, and other functions. It is widely used in various fields such as industrial production and food processing. However, because it requires heating a large amount of water, scale and other stains will form inside the steam, which will affect the cleanliness of the subsequent steam. Therefore, a special sewage discharge device is needed to clean these stains.

[0003] Patent application number 202320138645.6 discloses a steam generator with a sludge discharge device. By designing a first and second sludge discharge tank structure, the first tank structure is used for normal sludge discharge, while the second tank structure is in standby mode. The first tank structure slowly draws in a mixture of sludge and sediment deposited in the steam generator through a three-way pipe, enabling the steam generator to perform sludge discharge without stopping. Although this device can discharge sludge, the first and second tanks are difficult to clean, and prolonged use can easily lead to blockages. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a clean, convenient, and non-clogging steam generator drain device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the steam generator sewage discharge device includes a sewage discharge box connected to the sewage discharge port of the steam generator. The sewage discharge box includes a box body, a sewage inlet pipe connected to the upper part of the box body, a sewage discharge pipe set at the lower part of the box body, a cleaning mechanism set inside the box body, a water inlet connected to the box body, and a collection box connected to the bottom of the sewage discharge pipe.

[0006] The cleaning mechanism includes a rotating shaft that runs through the housing, a cleaning brush mounted on the rotating shaft, and a drive component that drives the rotating shaft to rotate.

[0007] Furthermore, the sewage tank has multiple components, the tank body is cylindrical, the sewage inlet pipe and sewage outlet pipe are staggered and each sewage outlet pipe is connected to the collection tank respectively.

[0008] Furthermore, a valve is provided at the upper part of the sewage inlet pipe, and the water inlet is located on the sewage inlet pipe below the valve.

[0009] Furthermore, there are multiple water inlets, and the multiple water inlets are arranged horizontally.

[0010] Furthermore, the cleaning mechanism also includes a row of stop pins disposed at the upper port of the drain pipe, the stop pins extending toward the brush side.

[0011] Furthermore, the bottom surface of the collection box is inclined, and a drain pipe is provided at the bottom of the collection box, with the lower end of each drain pipe connected to the collection box.

[0012] Furthermore, the side wall of the collection box is provided with a transparent viewing window.

[0013] This steam generator drain device connects to a drain box at the drain port of the steam generator. A cleaning brush is installed inside the drain box. After dirt enters the drain box from the steam generator, the cleaning brush, in conjunction with the cleaning water flow from the inlet, guides the dirt into the drain pipe. This cleans both the steam generator and the drain box, preventing dirt from remaining or adhering in the drain box. It is convenient to clean and avoids clogging. Attached Figure Description

[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1-8 As shown, the steam generator drain device includes a drain box connected to the drain port of the steam generator. The drain box includes a box body 1, a drain pipe 2 connected to the upper part of the box body 1, a drain pipe 3 set at the lower part of the box body 1, a cleaning mechanism 6 set inside the box body 1, a water inlet 4 connected to the box body 1, and a collection box 5 connected to the bottom of the drain pipe 3.

[0027] The cleaning mechanism 6 includes a rotating shaft 61 that passes through the housing 1, a cleaning brush 62 mounted on the rotating shaft 61, and a driving component 63 that drives the rotating shaft 61 to rotate.

[0028] The steam generator drain device connects to a drain box at the drain port of the steam generator. A cleaning brush 62 is installed inside the drain box. After dirt enters the drain box from the steam generator, the cleaning brush 62, together with the cleaning water flow from the inlet 4, guides the dirt into the drain pipe 3. This achieves the cleaning of dirt from the steam generator and the drain box, preventing dirt from remaining or adhering in the drain box. It is convenient to clean and avoids the formation of blockages.

[0029] The system comprises multiple sewage boxes. The box body 1 is cylindrical, with inlet pipes 2 and outlet pipes 3 staggered and each outlet pipe 3 connected to a collection box 5. The cylindrical box body 1 allows the cleaning brush 62 to thoroughly clean the interior of the box body 1 during rotation, eliminating any blind spots. A valve is located at the top of the inlet pipe 2, with a water inlet 4 positioned below the valve on the inlet pipe 2. This valve is normally closed during normal operation of the steam generator; it opens when cleaning is required, allowing dirt to enter the box body 1 through the steam generator's outlet.

[0030] There are multiple water inlets 4, which are arranged horizontally. During the sewage discharge process, the water inlets 4 can be opened to work with the cleaning brush 62 to clean the tank 1, while preventing dirt from adhering to the inside of the tank 1.

[0031] To achieve cleaning of the cleaning brush 62, the cleaning mechanism 6 also includes a row of baffle pins 8 located at the upper port of the drain pipe 3, with the baffle pins 8 extending towards the brush side. The row of baffle pins 8 can comb the cleaning brush 62 and also remove dirt stuck inside the cleaning brush 62.

[0032] The lower part of the drain pipe 3 is connected to the collection box 5. The bottom surface of the collection box 5 is inclined, and a drain pipe 51 is provided at the lower end of the collection box 5. The lower end of each drain pipe 3 is connected to the collection box 5, and a transparent window 52 is provided on the side wall of the collection box 5. During cleaning, the collection box 5 can be used as a temporary storage device to temporarily store dirt, and the dirt can be discharged to a preset location or into the equipment according to the storage situation.

[0033] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
