Description

Technical Field

[0001] This utility model belongs to the field of water pump technology, and relates to a stainless steel pump, and more particularly to a stainless steel vertical circulating pump. Background Technology

[0002] A circulating pump is a pump used in a device to transport circulating liquids for reaction, absorption, separation, and absorption liquid regeneration. It has a low head and is only used to overcome the pressure drop of the circulating system. Low-head pumps can be used, such as circulating water in heating pipes to heat it into hot water.

[0003] When circulating pumps are used in environments with poor water quality, the high amount of impurities in the water causes these impurities to frequently pass through the pump body, leading to blockages in the pump body passages and damage to the impeller. Manufacturers have addressed this issue by adding filters and cleaning devices. However, while existing filters and cleaning devices can remove impurities from the filter screen during cleaning, they cannot collect and process the removed impurities during the cleaning process. As a result, the removed impurities tend to accumulate in the pump body, leading to low cleaning efficiency.

[0004] For example, a stainless steel vertical circulating pump with application number 201921529940.4 includes a cavity, a first motor installed at the upper end of the cavity, a rectangular structure at the lower part of the cavity and a cylindrical structure at the upper end, the interior of the upper end of the cavity is evenly divided by a dividing ring, the output shaft of the first motor passes through the cavity and is equipped with an impeller, a filter plate is installed inside the lower end of the cavity, a reciprocating plate is installed on the filter plate, and a lever is set on the reciprocating plate to clean the filter plate.

[0005] The aforementioned patent uses a reciprocating plate to drive a lever to clean the filter plate. However, since the reciprocating plate is perpendicular to the filter plate, impurities are easily dropped during cleaning, causing them to accumulate at the bottom of the pump body and re-adhere to the filter plate when pumping water, resulting in low cleaning efficiency.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1 to 6 As shown, this utility model can be implemented through the following embodiments: A stainless steel vertical circulating pump includes a base 1, an inlet chamber 2 is provided above the base 1, a pump body 3 is installed above the inlet chamber 2, an installation part 21 is provided in the inlet chamber 2, the installation part 21 has an installation groove 211, a filter plate 4 is installed in the installation groove 211, a cleaning plate 5 is provided below the filter plate 4, a collection frame 51 is provided on the cleaning plate 5, a lead screw 22 and a lead screw 23 are connected to both sides of the cleaning plate 5, a bevel gear 221 is provided on the lead screw 22, the bevel gear 221 meshes with the bevel gear 222, the bevel gear 222 is connected to a motor 223, a dirt removal chamber 24 is provided outside the inlet chamber 2, and a support plate 11 is provided at the lower end of the base.

[0027] The filter plate 4 is used to filter the water flow entering the pump body 3 to prevent impurities in the water flow from entering the pump body 3; the cleaning plate 5 is used to clean the impurities adhering to the filter plate 4 when the pump body 3 is stopped, through the reciprocating motion of the motor 223, bevel gear 1 221 and bevel gear 222, sprocket 6 and chain belt 61, and the rotation of lead screw 1 22 and lead screw 23; the dirt removal chamber 24 is used to connect to the outside world, so that maintenance personnel can collect and remove impurities.

[0028] As shown in Figure 1 and Figure 3 As shown, sprockets 6 are installed on lead screw 1 22 and lead screw 23, and a chain belt 61 connects the sprockets 6. After lead screw 1 22 is driven by motor 223, the power on lead screw 1 22 is transmitted to lead screw 23 through sprockets 6 and chain belt 61, realizing synchronous rotation of lead screw 1 22 and lead screw 23, reducing the installation of motor 223, simplifying the structure and reducing costs.

[0029] like Figure 1 and Figure 2 As shown, a fixing plate 31 is provided on the pump body 3, and the fixing plate 31 is connected to the mounting part 21 by bolt 32. Bolt 32 fixes the pump body 3 and the water inlet chamber 2 by fixing the fixing plate 31 and the mounting part 21, and restricts the displacement of the filter plate 4 by fixing the fixing plate 31 and the mounting part 21.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the mounting groove 211 has a positioning groove 211a, and the filter plate 4 has a corresponding positioning part 41. The positioning part 41 has a fixing hole 412, through which a bolt 411 passes. The positioning part 41 cooperates with the positioning groove 211a to complete the installation of the filter plate 4 in the mounting part 21, and the bolt 411 passes through the mounting part 21, the fixing plate 31 and the fixing hole 412 to fix the filter plate 4, the water inlet chamber 2 and the pump body 3.

[0031] like Figure 2 and Figure 5 As shown, a cover 52 is installed on the collection frame 51, and a threaded rod 53 is provided on the cleaning plate 5, which passes through the collection frame 51 and the cover 52. The cover 52 is designed to open the collection frame 51, making it convenient for maintenance personnel to clean the debris inside the collection frame 51 in the decontamination chamber 24. Because there is a relative rotational relationship between the cover 52 and the collection frame 51, there is a slight gap between the cover 52 and the collection frame 51, allowing water inside the collection frame 51 to filter out through the gap. The threaded rod 53 is used to lock or open the cover 52 to prevent the cover 52 from remaining open and causing impurities to not be transferred to the decontamination chamber 24.

[0032] like Figure 2 , Figure 5 and Figure 6As shown, a scraper 54 is provided on the cleaning plate 5, and a baffle 55 is provided on the outside of the scraper 54. A gap 7 is left between the baffle 55 and the filter plate 4. Two sets of scrapers 54 and baffles 55 are provided and symmetrically distributed. The scraper 54 is used to scrape off impurities on the filter plate 4, and the baffle 55 is used to guide the impurities into the collection frame 51 when scraping off impurities. The gap 7 between the baffle 55 and the filter plate 4 can prevent the baffle 55 from scraping off the impurities on the filter plate 4, causing the impurities to fall into the water inlet chamber 2. The two sets of scrapers 54 and baffles 55 are provided and symmetrically distributed to facilitate the cleaning of impurities on the filter plate 4 when the cleaning plate 5 reciprocates, thereby improving the cleaning efficiency.

[0033] like Figure 2 and Figure 5 As shown, a connecting post 56 is provided below the collection frame 51, and a push plate 57 is connected to the connecting post 56. The push plate 57 is provided with an inclined surface 571, and a shovel groove 572 is provided on the inclined surface 571. The setting of the connecting post 56 enables the push plate 57 and the cleaning plate 5 to move synchronously, simplifying the structure. The inclined surface 571 on the push plate 57 faces the bottom of the water inlet chamber 2, and together with the shovel groove 572 opened on the inclined surface 571, it can collect and remove as much impurity as possible from the bottom of the water inlet chamber 2, improving cleaning efficiency.

[0034] like Figure 5 As shown, a collection port 58 is provided between the scraper 54 and the baffle 55. The collection port 58 facilitates the entry of impurities scraped off by the scraper 54 into the collection frame 51.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the cleaning chamber 24 is provided with an opening 241 and an opening 242. The opening 241 connects to a chamber 243. A water inlet 243a is provided in the chamber 243, and a screen 8 is provided on the water inlet 243a. A sewage outlet is provided in the chamber 243, and a sealing cover 9 is installed on the sewage outlet. The opening 241 allows the cover 52 of the collection frame 51 to enter the cleaning chamber 24, facilitating the cleaning of impurities in the collection frame 51. The water inlet 243a connects the inlet chamber 2 and the chamber 243, allowing the water inside the chamber 243 to flow back to the inlet chamber 2. The screen 8 filters impurities in the water flowing through the chamber 243, improving cleaning efficiency. The sealing cover 9 seals the sewage outlet to prevent water leakage from the sewage outlet when the pump body 3 is working.

[0036] like Figure 1 , Figure 2 and Figure 4As shown, opening 242 connects to chamber 244, and chamber 244 is provided with a drain port 244a. A sealing cover 244a is installed on the drain port 244a. Opening 242 is used by push plate 57 to push the collected impurities into chamber 244; drain port 244a is used to drain water when pump body 3 stops and remove some impurities through water flow; sealing cover 244a is used to seal drain port 244a to prevent water from leaking from drain port 244a when pump body 3 is working.

[0037] The working principle of this utility model is as follows: When cleaning is required, the pump body 3 is stopped so that external water no longer flows through the pump body 3. The bolts on the sealing cover 10 are opened to drain the water from the pump body 3. After the water is drained, the pump body 3 is left to stand for a period of time. Then the motor 223 is started, which causes the lead screw 1 22 and lead screw 23 to drive the cleaning plate 5 and push plate 57 to move. The cleaning plate 5 collects the impurities on the filter plate 4 into the collection frame 51. The push plate 57 collects the impurities at the bottom of the water inlet chamber 2. After the collection frame 51 moves to the dirt removal chamber 24, the motor 223 is stopped. The sealing cover 9 is opened, and the threaded rod 53 is turned to open the buckle cover 52. The impurities inside the collection frame 51, chamber 1 243 and chamber 2 244 are removed. After cleaning, the threaded rod 53 is reset to lock the buckle cover 52. The sealing cover 9 and sealing cover 2 10 are reset. Finally, the motor 223 is started to reset the cleaning plate 5 and refill the pump body 3 with water to start the pump body 3.
