Description

Technical Field

[0001] This utility model belongs to the field of condensate collection technology, specifically relating to a steam condensate collection device. Background Technology

[0002] Steam is formed by heating water to above the boiling point, changing from a liquid state to a gaseous state. During the heat transfer process, steam gradually releases heat, eventually forming tail steam and condensate with a certain temperature and pressure. In order to achieve the goal of energy conservation and environmental protection, the chemical industry usually collects the steam condensate generated in the production process separately and recycles it. This process usually relies on specially designed steam condensate collection devices.

[0003] The working principle of common steam condensate collection devices is to introduce high-temperature and high-pressure exhaust steam and condensate into the condensate collection tank through the inlet. When the condensate accumulates to a certain amount, it is discharged through the drain and recycled. Although this device can effectively collect condensate, there are still some problems in actual operation that need to be solved.

[0004] Steam condensate often carries a certain amount of impurities. Although some condensate collection tanks are equipped with internal filters to intercept these impurities, the filters are prone to clogging due to the accumulation of impurities over time. Once the filters are clogged, the entire tank needs to be disassembled for cleaning and maintenance, which not only affects the filtration efficiency but also significantly increases the maintenance cost and operational complexity of the equipment. Utility Model Content

[0005] In view of this, the present invention provides a steam condensate collection device, which can reverse the flow of filtered water into a negative pressure hood through a filtration mechanism, thereby backwashing the filter screen. At the same time, it is linked with a brush roller to achieve a dual self-cleaning function of brushing and negative pressure adsorption. This ensures that the filter screen always maintains high flowability and avoids secondary pollution from impurities. It can simultaneously complete condensate filtration and filter screen self-cleaning without manual disassembly and rinsing, significantly improving filtration efficiency and reducing maintenance costs.

[0006] To solve the above-mentioned technical problems, this utility model provides a steam condensate collection device, including a collection tank and a filtration mechanism disposed therein. The filtration mechanism includes a filter screen disposed in the collection tank, and a rotating rod rotatably connected between the filter screen and the bottom of the collection tank. A negative pressure cover is provided at the upper end of the outer arc surface of the rotating rod. The lower opening of the negative pressure cover is matched with the upper filter surface of the filter screen. A negative pressure port is provided at one end of the negative pressure cover. The collection tank is also provided with a suction component for providing negative pressure suction to the negative pressure port, which can reverse the flow of filtered water into the negative pressure cover, thereby backwashing the filter screen. At the same time, the brush roller is linked to achieve a dual self-cleaning function of brushing and negative pressure adsorption. This ensures that the filter screen always maintains high flowability and avoids secondary pollution by impurities. It can simultaneously complete condensate filtration and filter screen self-cleaning without manual disassembly and rinsing, significantly improving filtration efficiency and reducing maintenance costs.

[0007] The filtration mechanism includes multiple brush rollers rotatably connected to both ends of the inner cavity of the negative pressure hood. All brush rollers are in contact with the upper filter surface of the filter screen, thus playing a role in physical cleaning.

[0008] The suction assembly includes a suction channel located inside the rotating rod. The suction end of the suction channel is connected to the negative pressure port, which serves as a transmission mechanism.

[0009] The suction assembly also includes a fixed sleeve at the lower end of the collection tank. The fixed sleeve is rotatably connected to the lower end of the outer arc surface of the rotating rod. The liquid outlet end of the suction channel is connected to the fixed sleeve. A connecting pipe is provided in the liquid outlet on the outer arc surface of the fixed sleeve, which provides suction without affecting the rotation of the rotating rod.

[0010] A motor is installed at the lower end of the collection tank, and the output shaft of the motor is fixedly connected to the lower end of the rotating rod, thus providing the driving source.

[0011] The filter screen has an inverted conical cross-section, which optimizes condensate distribution and filtration efficiency.

[0012] The outer arc surface of the collection tank is equipped with an observation window, which allows for real-time monitoring of the internal filtration and rinsing status.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0014] 1. After the steam condensate enters the collection tank, it undergoes initial impurity interception through a filter screen. The filter screen adopts an inverted conical structure, which optimizes condensate distribution and filtration efficiency. Subsequently, the drive rotating rod and its fixed negative pressure hood rotate synchronously. The brush roller continuously contacts the upper filter surface of the filter screen, physically brushing away the particles attached to the filter screen. At the same time, it rotates due to friction. Simultaneously, the suction component provides negative pressure suction to the negative pressure hood, thereby drawing the filtered water back into the negative pressure hood to perform reverse rinsing of the filter screen. At the same time, the impurities brushed off by the brush roller and the dirt on the surface of the filter screen are sucked in through the lower opening of the negative pressure hood and discharged through the negative pressure port and suction component. This linkage design achieves a dual self-cleaning function of brushing and negative pressure adsorption, ensuring that the filter screen always maintains high flowability and avoiding secondary contamination by impurities. The observation window can monitor the internal filtration and rinsing status in real time, facilitating timely maintenance. It can simultaneously complete condensate filtration and filter screen self-cleaning without manual disassembly and rinsing, significantly improving filtration efficiency and reducing maintenance costs.

[0015] 2. When the external sewage pump starts, it provides negative pressure suction to the negative pressure hood through the connecting pipe, suction channel, and negative pressure port, so that the suction of impurities is not affected while the rotating rod is rotating.

[0016] 3. The observation window allows for real-time monitoring of the internal filtration and flushing status, facilitating timely maintenance. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figures 1-4The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] This embodiment provides a steam condensate collection device, such as... Figures 1-4 As shown: It includes a collection tank 100 and a filtration mechanism disposed therein. The filtration mechanism includes a filter screen 200 disposed inside the collection tank 100. A rotating rod 201 is rotatably connected between the filter screen 200 and the bottom of the collection tank 100. A negative pressure cover 202 is provided at the upper end of the outer arc surface of the rotating rod 201. The lower end opening of the negative pressure cover 202 is engaged with the upper end filter surface of the filter screen 200. A negative pressure port 203 is provided at one end of the negative pressure cover 202. The collection tank 100 is also provided with a suction component for providing negative pressure suction to the negative pressure port 203. The filtration mechanism includes multiple brush rollers 204 rotatably connected to both ends of the inner cavity of the negative pressure cover 202. All multiple brush rollers 204 are in contact with the upper end filter surface of the filter screen 200. The cross-section of the filter screen 200 is an inverted conical structure.

[0024] After the steam condensate enters the collection tank 100, it undergoes initial impurity interception through the filter screen 200. The filter screen 200 adopts an inverted conical structure, which optimizes the distribution of condensate and filtration efficiency. Subsequently, the drive rotating rod 201 and its fixed negative pressure cover 202 rotate synchronously. The brush roller 204 continuously contacts the upper filter surface of the filter screen 200, physically brushing away the particles attached to the filter screen 200. At the same time, it rotates due to friction. Simultaneously, the suction component provides negative pressure suction to the negative pressure cover 202, thereby drawing the filtered water back into the negative pressure cover 202, thus cleaning the filter screen 200. The filter screen 200 is backwashed, and the impurities brushed off by the brush roller 204 and the dirt on the surface of the filter screen 200 are sucked in through the lower opening of the negative pressure cover 202 and discharged through the negative pressure port 203 and the suction component. This linkage design realizes the dual self-cleaning function of brushing and negative pressure adsorption, which not only ensures that the filter screen 200 always maintains high flowability, but also avoids secondary pollution by impurities. The observation window can monitor the internal filtration and rinsing status in real time, which is convenient for timely maintenance. It can simultaneously complete condensate filtration and filter screen self-cleaning without manual disassembly and rinsing, which significantly improves filtration efficiency and reduces maintenance costs.

[0025] like Figures 1-4 As shown, the suction assembly includes a suction channel 300 disposed within the rotating rod 201. The suction end of the suction channel 300 is connected to the negative pressure port 203. The suction assembly also includes a lower fixing sleeve 301 disposed within the collection tank 100. The fixing sleeve 301 is rotatably connected to the lower end of the outer arc surface of the rotating rod 201. The liquid outlet end of the suction channel 300 is connected to the fixing sleeve 301. A connecting pipe 302 is provided inside the liquid outlet on the outer arc surface of the fixing sleeve 301.

[0026] When the external sewage pump is started, it provides negative pressure suction to the negative pressure cover 202 through the connecting pipe 302, the suction channel 300, and the negative pressure port 203. The suction operation of impurities is not affected when the rotating rod 201 rotates.

[0027] like Figures 1-4 As shown, a motor 400 is provided at the lower end of the collection tank 100. The output shaft of the motor 400 is fixedly connected to the lower end of the rotating rod 201, providing a driving source for the rotating rod 201.

[0028] like Figure 1 As shown, the outer arc surface of the collection tank 100 is provided with an observation window, which can monitor the internal filtration and flushing status in real time, facilitating timely maintenance.

[0029] The working principle of the steam condensate collection device provided by this utility model is as follows: First, connect the liquid inlet at the upper end of the collection tank 100 to the external steam condensate outlet. Then, connect the connecting pipe 302 to the liquid inlet of the external sewage pump. After the steam condensate enters the collection tank 100, it undergoes preliminary impurity interception through the filter screen 200. The filter screen 200 adopts an inverted conical structure, which can optimize the condensate distribution and filtration efficiency. Subsequently, the motor 400 is started, and its output shaft drives the rotating rod 201 and its fixed negative pressure cover 202 to rotate synchronously. The brush roller 204 continuously contacts the filter surface at the upper end of the filter screen 200, physically brushing away the particles attached to the filter screen 200. At the same time, it rotates due to friction. Simultaneously, the external sewage pump is started and passes through the connecting pipe 302 and the suction channel 300. The negative pressure port 203 provides negative pressure suction to the negative pressure cover 202, thereby drawing the filtered water back into the negative pressure cover 202 to backwash the filter screen 200. At the same time, impurities brushed off by the brush roller 204 and dirt on the surface of the filter screen 200 are sucked in through the lower opening of the negative pressure cover 202 and transported through the negative pressure port 203, the suction channel 300 and the fixing sleeve 301, and finally discharged through the connecting pipe 302. This linkage design realizes the dual self-cleaning function of brushing and negative pressure adsorption, which not only ensures that the filter screen 200 always maintains high flowability, but also avoids secondary pollution by impurities. The observation window can monitor the internal filtration and rinsing status in real time, which is convenient for timely maintenance. It can simultaneously complete condensate filtration and filter screen self-cleaning without manual disassembly and rinsing, significantly improving filtration efficiency and reducing maintenance costs.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
