DETAILED DESCRIPTION

[0030] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0031] In the present disclosure, unless otherwise stated, the directional words used, such as "upper, lower", are generally defined in terms of the normal use state of the boiler sampling water recovery device 100. "Inside, outside" refer to the inside and outside of the contour of the corresponding component. In addition, the terms "first", "second", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance.

[0032] like Figures 1 to 6 As shown, the present disclosure provides a boiler sampling water recovery device 100, including a housing 1, a filter screen 2 and a cleaning assembly 3. The housing 1 has a filter chamber 11 inside, the filter screen 2 is located in the filter chamber 11, and the housing 1 is provided with a water inlet 12 and a water outlet 13. One end of the water inlet 12 and one end of the water outlet 13 are both connected to the filter chamber 11, and the other end of the water inlet 12 is used to communicate with the sampling water pipe of the boiler, and the other end of the water outlet 13 is used to communicate with the water inlet pipe of the boiler. A long hole 14 is formed on the housing 1, and the long hole 14 is used for the filter screen 2 to pass through. The filter screen 2 is provided with a pulling part 21, and the pulling part 21 is located outside the housing 1, and at least part of the filter screen 2 can be pulled to the outside of the housing 1.

[0033] The cleaning component 3 is installed on the shell 1 and is located outside the shell 1. The cleaning component 3 includes a scraper 31. A scraping edge 311 is formed at one end of the scraper 31. The scraping edge 311 is used to contact the surface of the filter 2 during the movement of the filter 2 to scrape impurities on the surface of the filter 2.

[0034] Through the above technical solution, the filter screen 2 can filter the sampled water in the filter chamber 11 when in use, so that the sampled water can be returned to the boiler for continued use. When the sampling water recovery device is regularly maintained, the filter screen 2 can be pulled out of the housing 1 by the pulling portion 21. In the process of pulling the filter screen 2 out of the housing 1, the scraping edge 311 of the scraper 31 can contact the filter screen 2 and scrape off the impurities on the surface of the filter screen 2, thereby completing the cleaning of the filter screen 2. In this way, the workload required for cleaning the filter screen 2 is reduced, the time for equipment maintenance is shortened, and the work efficiency is improved. At the same time, since the filter screen 2 is easy to clean, the cleaning frequency of the filter screen 2 can be increased, thereby ensuring the filtering effect of the filter screen 2 and preventing the filtering capacity of the filter screen 2 from decreasing due to long-term uncleaning, thereby affecting the quality of the sampled water returned to the boiler.

[0035] Alternatively, if Figure 2 , Figure 3 and Figure 4 As shown, the cleaning assembly 3 also includes an impurity collection box 32, which is detachably mounted on the housing 1 and is located below the long hole 14, with the opening of the impurity collection box 32 facing upward, and the projection of the scraping edge 311 in the up-down direction is located inside the impurity collection box 32. During the cleaning process of the scraper 31, as the filter 2 moves, the impurities on the surface of the filter 2 are scraped off by the scraping edge 311 of the scraper 31 and fall under the action of gravity. Since the impurity collection box 32 is arranged below the long hole 14, the opening of the impurity collection box 32 faces upward, and the projection of the scraping edge 311 in the up-down direction is located inside the impurity collection box 32, it can be ensured that the impurities falling from the filter 2 can fall into the impurity collection box 32, thereby preventing the scraped impurities from causing pollution to the site and keeping the work site clean and tidy.

[0036] Optionally, a connection block may be provided at the bottom of the impurity collection box 32, and the connection block may be provided in a third chute located at the lower side of the scraper 31 and detachably connected to the third chute. The impurity collection box 32 is provided in the third chute so that the scraper 31 and the impurity collection box 32 are coplanar, that is, the projection of the scraping edge 311 of the scraper 31 in the vertical direction is located in the impurity collection box 32. At the same time, the impurity collection box 32 is provided in the third chute so that the existing structure can be used to fix the impurity collection box 32, which is conducive to simplifying the structure of the cleaning component 3.

[0037] In order to improve the sealing performance of the boiler sampling water recovery device 100, optionally, as Figure 2 and Figure 3As shown, the boiler sampling water recovery device 100 further includes a filter housing 4, which is disposed inside the housing 1, and the filter housing 4 and the inner wall of the housing 1 together enclose a filter chamber 11. A seal 22 is disposed at one end of the filter screen 2 close to the pulling portion 21, and the seal 22 is used to seal and contact with the hole wall of the long hole 14 to seal the gap between the filter screen 2 and the hole wall of the long hole 14.

[0038] The filter housing 4 and the outer shell 1 together enclose a filter cavity 11, and a long hole 14 is provided on the outer shell 1. On the one hand, the filter screen 2 can be located outside the outer shell 1 after passing through a layer of the outer shell 1, that is, the matching gap between the movable filter screen 2 and the filter housing 4 and the outer shell 1 is reduced, and a seal 22 is provided at the gap to reduce the probability of leakage of the sampled water; on the other hand, the area of ​​the shell required for setting the filter cavity 11 can be reduced, which can save materials and reduce manufacturing costs.

[0039] The present disclosure does not limit the specific structure of the filter housing 4. In one embodiment provided in the present disclosure, Figure 2 As shown, the filter housing 4 includes a top plate 41 , a bottom plate, and a side plate 42 connected between the top plate 41 and the bottom plate. The top plate 41 , the bottom plate, the side plate 42 and the inner wall of the housing 1 together enclose a filter chamber 11 .

[0040] Optionally, the filter 2 may include a filter body 23 and an installation frame, the filter body 23 is installed in the installation frame, and the first sliders 25 extending along the moving direction of the filter 2 are provided on opposite sides of the installation frame, and the top plate 41 and the bottom plate are provided with a first slide groove extending along the moving direction of the filter 2, and the first slider 25 is slidably fitted in the first slide groove.

[0041] Through the sliding cooperation between the first slider 25 and the first slide groove, the filter screen 2 can move between the top plate 41 and the bottom plate of the filter housing 4, so as to be moved out of the housing 1 or into the housing 1 through the pulling portion 21. Thus, it is convenient for the scraper 31 to clean the impurities on the filter screen body 23.

[0042] Alternatively, if Figure 5 As shown, a stopper 24 is provided at one end of the installation frame away from the pulling portion 21, and the stopper 24 can abut against the inner wall of the housing 1 during the movement of the filter 2. In order to prevent the filter 2 from completely falling out of the housing 1 during the process of pulling out the housing 1, a stopper 24 is provided at one end of the installation frame away from the pulling portion 21. When the filter body 23 is completely located outside the housing 1, the stopper 24 can abut against the inner wall of the housing 1, thereby limiting the end of the installation frame away from the pulling portion 21 in the housing 1, preventing the filter 2 from falling out of the housing 1 as a whole, and further increasing the convenience of cleaning.

[0043] To improve the filtering capacity, optionally, Figure 2 , Figure 3 and Figure 4 As shown, there are multiple filter screens 2, which are arranged at intervals, there are multiple long holes 14, and the multiple filter screens 2 are arranged one by one with the multiple long holes 14. The scraper 31 is movably mounted on the housing 1, and the moving direction of the scraper 31 is parallel to the arrangement direction of the multiple filter screens 2. The multiple filter screens 2 can filter the sampled water multiple times to improve the filtering effect. At the same time, the moving direction of the scraper 31 is parallel to the arrangement direction of the multiple filter screens 2, so that the scraper 31 can move to make the scraping edge 311 contact with the surface of different filter screens 2 to scrape impurities on the surface of different filter screens 2, further improving the cleaning ability.

[0044] Optionally, a gripping portion may be further provided on the scraper 31. The gripping portion facilitates the operator to grip the scraper 31 when moving the scraper 31, thereby improving the convenience of operation.

[0045] In order to arrange the scraper 31 on the outer wall of the housing 1, optionally, as Figure 3 , Figure 4 and Figure 6 As shown, the cleaning assembly 3 also includes two mounting plates 33, which are mounted on the outer wall of the shell 1, and the two mounting plates 33 are relatively arranged in a direction perpendicular to the moving direction of the scraper 31, and the scraper 31 and multiple filters 2 are located between the two mounting plates 33, and the mounting plates 33 extend along the moving direction of the scraper 31. Second sliders 312 are formed on the opposite sides of the scraper 31, and second slide grooves 331 are formed on the side of the two mounting plates 33 close to the scraper 31, and the second slider 312 slides in cooperation with the second slide groove 331.

[0046] The two mounting plates 33 are mounted on the outer wall of the housing 1, and the second slider 312 cooperates with the second slide groove 331, so that the two sides of the scraper 31 can be respectively clamped on the two mounting plates 33, thereby mounting the scraper 31 on the outer wall of the housing 1. At the same time, the second slider 312 and the second slide groove 331 are slidably matched, and the two mounting plates 33 extend along the moving direction of the scraper 31, so that the scraper 31 can move along the arrangement direction of the multiple filter screens 2, thereby cleaning different filter screens 2. The mounting plates 33 respectively located on both sides of the scraper 31 can also fix the scraper 31 on both sides of the scraper 31, and guide the scraper 31, thereby improving the installation stability and movement stability of the scraper 31.

[0047] Alternatively, if Figure 2As shown, the boiler sampling water recovery device 100 also includes a water pump 5 and a water storage tank 6, which are both arranged in the housing 1, the water inlet of the water pump 5 is connected to the filter chamber 11, the water outlet of the water pump 5 is connected to the water storage tank 6, and the water outlet of the water storage tank 6 is connected to the water outlet 13. The sampled water filtered by the filter screen 2 enters the water storage tank 6 from the filter chamber 11 under the drive of the water pump 5. Due to the drive of the water pump 5, a unidirectional water flow can be formed between the filter chamber 11 and the water storage tank 6, thereby preventing the filtered sampled water from flowing back and mixing with the unfiltered sampled water, thereby improving the filtering efficiency.

[0048] Alternatively, if Figure 1 and Figure 2 The water inlet part 12 shown is an inlet pipe, and the water outlet part 13 is an outlet pipe. The inlet pipe and the outlet pipe are both provided with switch valves on one end away from the shell 1. The switch valves can control the on-off of the water path in the inlet pipe and the outlet pipe. On the one hand, the switch valves on the inlet pipe and the outlet pipe can be closed at the same time when the device is overhauled, which is convenient for the maintenance of the boiler sampling water recovery device 100 and prevents the sampling water in the filter chamber 11 from flowing out; on the other hand, the switch valve located at the outlet pipe can be opened after the water storage tank 6 is full or the boiler needs water, so that the water supply is more flexible.

[0049] Since the water temperature in the boiler is relatively high, water and water vapor usually coexist. In order to better filter the sampled water, it is optional, such as Figure 2 As shown, the boiler sampling water recovery device 100 also includes a condenser 7, which is arranged in the housing 1, and the water inlet pipe of the condenser 7 is connected to the water inlet pump 5, and the water outlet pipe of the condenser 7 is connected to the filter chamber 11. Through the extraction of the water inlet pump 5, the sampling water in the sampling water pipe enters from the water inlet pipe of the condenser 7, and is condensed by the condenser 7. The impurities in the water vapor can enter the liquid water after condensation, and then be filtered by the filter 2 to improve the water quality of the sampling water. In addition, the temperature of the sampling water cooled by the condenser 7 is relatively low, which can reduce the damage to the filter 2 due to high temperature and extend the service life of the filter 2.

[0050] Alternatively, if Figure 2 and Figure 4 As shown, the condenser 7 is located above the filter chamber 11. The boiler sampling water recovery device 100 also includes a support plate, which is located between the condenser 7 and the filter chamber 11. One side of the support plate is connected to the inner wall of the shell 1, and the condenser 7 is installed on the support plate. Water vapor and water enter the condenser 7 through the water inlet pipe of the condenser 7, and after heat exchange in the condenser 7, they become liquid water with a lower temperature, and then are discharged into the filter chamber 11 through the water outlet pipe of the condenser 7. By arranging the condenser 7 above the filter chamber 11, the condensed sampling water can flow into the filter chamber 11 under the action of gravity, thereby reducing the setting of the water pump, further simplifying the structure of the boiler sampling water recovery device 100, and reducing the energy consumption of the device.

[0051] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0052] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0053] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
