Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for thermal electric boilers, and specifically to a water supply device for thermal electric boilers. Background Technology

[0002] Thermal power boilers play a vital role in modern industrial production and centralized heating. During boiler operation, the consumed water needs to be continuously replenished to maintain the system's normal operation. The quality of the replenishment water directly affects the boiler's safe, efficient operation and service life. Substandard replenishment water (such as water containing excessive impurities or with excessive hardness) can lead to boiler scaling, corrosion, and even safety accidents. Therefore, boiler replenishment water devices are typically equipped with filtration systems to ensure that the replenishment water meets standards.

[0003] However, traditional water supply systems typically employ single or integrated filtration systems. When filter modules (such as filter elements or media) become clogged or fail and require cleaning or replacement, the entire water supply system must be shut down, resulting in an interruption of boiler water supply. For thermal power boilers that require continuous operation, a shutdown of the water supply system can severely impact the continuity and stability of heating or power generation.

[0004] Therefore, there is an urgent need to design a water supply device for thermal power boilers to solve the problems of inconvenient maintenance of filter modules and the need for shutdown to replace them in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a water supply device for a thermal power boiler to solve the problems in the background technology, such as the need for complete shutdown and replacement after the filter module becomes clogged, and the inconvenience of maintenance.

[0006] The technical solution adopted by this utility model to solve the above problems is: a water supply device for a thermal power boiler, including a base, a water storage tank fixedly installed on the base, an inlet on one side of the water storage tank, an outlet at the bottom, and the outlet being connected to the boiler through a pump body and a pipeline.

[0007] The water storage tank has a water collection cylinder at the center that is connected to the water outlet. Several sets of partitions are evenly spaced around the outside of the water collection cylinder. The partitions and the water collection cylinder divide the inner cavity of the water storage tank into several sets of fan-shaped cross-section filter chambers distributed around the circumference. Filter modules are detachably connected inside the filter chambers.

[0008] The water collection cylinder is provided with several through holes in its circumference. The through holes are located in the area of ​​the filter module on the outer circumferential wall of the water collection cylinder, so that the water in the filter chamber enters the water collection cylinder through the through holes after being filtered by the filter module.

[0009] The water storage tank is equipped with an inlet pipe connected to the water inlet. Several inlet valves are arranged on the inlet pipe, and the number of inlet valves is the same as the number of filter chambers, so that each filter chamber is connected to the inlet pipe through an inlet valve.

[0010] Preferably, the filter module includes a support frame and filter material filled in the frame. Limiting protrusions are provided on both sides of the partition. The support frame is vertically inserted and slidably disposed between the limiting protrusions of two adjacent sets of partitions, and the edge of the support frame is provided with a continuous silicone sealing strip.

[0011] Preferably, the filter chamber is equipped with a fan-shaped cover, and protrusions are provided on the lower edge of the straight sides of the cover. The upper end of the limiting protrusion is provided with a slot that is compatible with the protrusion. Two sets of lifting rings are symmetrically arranged on the upper end of the filter module. The cover is provided with a circular hole corresponding to the position of the lifting ring, and the diameter of the circular hole is larger than the maximum outer diameter of the lifting ring.

[0012] Preferably, the filter material consists of a PP cotton layer, an activated carbon granule layer, and a quartz sand layer arranged sequentially from the inside out, wherein the PP cotton layer is closer to the water collection cylinder and the quartz sand layer is closer to the filter chamber.

[0013] Preferably, the water collection cylinder is equipped with a float, and a marker rod is provided at the upper end of the float. The upper end of the water storage tank is equipped with a cover, and the cover has a through hole for the marker rod to pass through. The marker rod is divided into different colored sections from top to bottom, and an indicator frame is provided at the upper end of the cover, with an indicator ring at the upper end of the indicator frame.

[0014] Preferably, the bottom surface of the water collecting cylinder is provided with a water outlet cylinder that is connected to the water outlet, and a guide groove is provided on the outer peripheral wall of the water outlet cylinder near the bottom. The guide groove is used to guide the water in the water collecting cylinder into the water outlet cylinder through the guide groove when the water level in the water collecting cylinder is low and the lower surface of the float is in contact with the top of the water outlet cylinder.

[0015] Preferably, the bottom of the water storage tank is provided with a drain port corresponding to each filter compartment area, and a sealing cap is threaded to the drain port.

[0016] Preferably, the outer peripheral wall of the water storage tank is provided with at least one set of transparent windows.

[0017] Compared with the prior art, this utility model has the following advantages and effects:

[0018] This invention divides the water storage tank into several independent filter compartments using partitions and a water collection cylinder, and each filter compartment is equipped with an independent inlet valve. When a filter module in a certain filter compartment needs cleaning or replacement, the operator only needs to close the corresponding inlet valve to cut off the water supply to that compartment. Maintenance or replacement of that module can be performed without affecting the normal operation of other filter compartments. This avoids the problem of the entire water supply system shutting down due to the failure of a single filter unit, and helps maintain the continuity and stability of the thermal power boiler's operation.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0027] Example:

[0028] See Figure 1 - Figure 6In this embodiment, a water supply device for a thermal power boiler is disclosed, specifically used in the circulating water system of a thermal power boiler to provide filtered and purified supply water. Specifically, it includes a base 1, on which a water storage tank 2 is fixedly mounted. The water storage tank 2 has an inlet 21 on one side and an outlet 22 at its bottom. The outlet 22 is connected to the boiler via a pump body 3 and a pipeline.

[0029] The water storage tank 2 has a water collection cylinder 4 connected to the water outlet 22 at its center. Several sets of partitions 5 are evenly spaced around the outside of the water collection cylinder 4. The partitions 5 and the water collection cylinder 4 divide the inner cavity of the water storage tank 2 into several sets of fan-shaped cross-section filter chambers 6 distributed around the circumference. A filter module 7 is detachably connected inside the filter chamber 6.

[0030] The water collection cylinder 4 is provided with several through holes 41 around its circumference. The through holes 41 are opened in the area of ​​the outer peripheral wall of the water collection cylinder 4 corresponding to the filter module 7, so that the water in the filter chamber 6 enters the water collection cylinder 4 through the through holes 41 after being filtered by the filter module 7.

[0031] The water storage tank 2 is equipped with a water inlet pipe 10 connected to the water inlet 21. Several water inlet valves 11 are arranged on the water inlet pipe 10. The number of water inlet valves 11 is the same as the number of filter chambers 6, so that each filter chamber 6 is connected to the water inlet pipe 10 through a water inlet valve 11.

[0032] Specifically, in this embodiment, the water replenishment device of this utility model operates as follows: During operation, raw water enters the water inlet pipe 10 through the inlet 21 and flows into the corresponding filter chamber 6 through each opened inlet valve 11. Inside the chamber, the water passes through the filter module 7 under the action of gravity or inlet pressure, and the filtered clean water enters the central water collection cylinder 4 through the through hole 41. The clean water is collected in the water collection cylinder 4 and sent to the boiler through the outlet 22 and the pump body 3.

[0033] When maintenance is required on the filter module 7 of one of the filter chambers 6, the operator only needs to close the inlet valve 11 corresponding to that chamber, at which point raw water will no longer enter that chamber. The other filter chambers 6 and their corresponding inlet valves 11 remain open and continue normal operation. After closing the inlet valve 11, the operator removes the old filter module 7, replaces it with a new or cleaned module, and opens the inlet valve 11, and the filter chamber 6 resumes operation. Throughout the process, the total water output of the water replenishment device is only temporarily reduced (due to the lack of clean water replenishment from one filter chamber 6), and is not completely interrupted. It should be noted that when replacing the filter module 7, a baffle 12 adapted to the side wall of the water collection cylinder 4 is also required. The baffle 12 can be inserted between the filter module 7 and the water collection cylinder 4 to seal the through hole 41 of the water collection cylinder 4 on the side of the filter chamber 6.

[0034] This invention divides the water storage tank 2 into several independent filter chambers 6 using partitions 5 and a water collection cylinder 4, and equips each filter chamber 6 with an independent inlet valve 11. When a filter module 7 in a filter chamber 6 needs cleaning or replacement, the operator only needs to close the corresponding inlet valve 11 to cut off the water supply to that chamber. Maintenance or replacement of that module can be performed without affecting the normal operation of other filter chambers 6. This avoids the problem of the entire water supply system shutting down due to a single filter unit failure, and helps maintain the continuity and stability of the thermal power boiler operation.

[0035] In this embodiment, the filter module 7 includes a support frame and filter material filled within the frame. Limiting protrusions 8 are provided on both sides of the partition 5, and the support frame is vertically inserted and slidably positioned between the limiting protrusions 8 of two adjacent sets of partitions 5. A continuous silicone sealing strip 71 is provided on the edge of the support frame that contacts the limiting protrusions 8. After insertion, the silicone sealing strip 71 is pressed tightly, effectively preventing the raw water in the filter chamber 6 from leaking directly into the water collection cylinder 4 without passing through the filter material. Furthermore, a groove 51 for supporting the water inlet pipe 10 is also provided at the upper end of the partition 5.

[0036] See Figure 4 The filter chamber 6 is equipped with a fan-shaped cover 9. The lower edges of the straight sides of the cover 9 (near the partition 5) are provided with protrusions 91. The upper end of the limiting protrusion 8 (i.e., the top two sides of the partition 5) has slots 81 that fit the protrusions 91. After the cover 9 is closed, the protrusions 91 are embedded in the slots 81, making the cover 9 securely positioned. For ease of hoisting, two sets of lifting rings 72 are symmetrically arranged on the upper end of the filter module 7 (its support frame). The cover 9 has a circular hole 92 at the position corresponding to the lifting ring 72, the diameter of which is larger than the maximum outer diameter of the lifting ring 72. Thus, during maintenance, hoisting tools (such as hooks) can directly pass through the circular holes 92 on the cover 9 to hook the lifting rings 72, vertically hoisting or inserting the filter module 7 without first removing the cover 9, simplifying the operation.

[0037] In this embodiment, the filter material has a multi-layer composite structure, consisting of a PP cotton layer, an activated carbon granule layer, and a quartz sand layer from the inside out (i.e., from the side closest to the water collection cylinder 4 to the side closest to the outer wall of the filter chamber 6). The PP cotton layer is closer to the water collection cylinder 4, and the quartz sand layer is closer to the filter chamber 6. Therefore, the actual filtration sequence of the water flow is as follows: first, it flows through the outermost quartz sand layer to remove large suspended solids and impurities; then, it flows through the middle activated carbon granule layer, utilizing the adsorption properties of activated carbon to remove discoloration, odor, residual chlorine, and some organic matter from the water; finally, it flows through the innermost PP cotton layer for precision filtration, intercepting even finer particles to ensure the cleanliness of the water ultimately entering the water collection cylinder 4.

[0038] See Figure 5To monitor the level of filtered water in the water collection cylinder 4, a float 42 is installed inside the water collection cylinder 4. A marker rod 43 is fixed to the upper end of the float 42. The top of the water storage tank 2 is provided with a cover 25, and a perforation is provided on the cover 25 for the marker rod 43 to pass through. The marker rod 43 is painted with different colored sections from top to bottom (e.g., red, green, and yellow) to indicate different water level heights. At the position corresponding to the perforation on the upper end of the cover 25, an indicator frame 13 is also provided, and an indicator ring 14 is provided at the upper end of the indicator frame 13. By observing the color corresponding to the marker rod 43 at the indicator ring 14, the operator can intuitively judge the approximate water level in the water collection cylinder 4 (e.g., green indicates normal, red indicates too low, and yellow indicates water shortage).

[0039] To ensure effective water discharge even at low water levels, the inner bottom surface of the water collecting cylinder 4 is equipped with an upwardly protruding water outlet cylinder 44 (its top end is below the lower limit of the normal operating water level), and the water outlet cylinder 44 is connected to the water outlet 22. See also Figure 6 Near the bottom of the outer peripheral wall of the outlet cylinder 44, a guide channel 45 is provided. When the water level in the collecting cylinder 4 is extremely low and the lower surface of the float 42 has already contacted the top of the outlet cylinder 44, the remaining water can still flow into the outlet cylinder 44 through these guide channels 45 and eventually be drawn out by the pump body 3. This effectively prevents the pump body 3 from being damaged due to cavitation.

[0040] In this embodiment, for ease of cleaning and maintenance (which requires shutdown for cleaning), a drain port 23 is provided at the bottom of the water tank 2 in the area corresponding to each filter chamber 6. The drain port 23 is normally sealed with a threaded sealing cap. In addition, at least one set of transparent windows 24 is provided on the outer peripheral wall of the water tank 2, one set for each filter chamber 6. Operators can observe the water level and turbidity of the raw water in the filter chamber 6 through the transparent windows 24, so as to increase the water inflow or drain and replace the filter module 7 as needed.

[0041] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
