Description

Technical Field

[0001] The utility model relates to the field of solar salt production technology, in particular to a denitrification self-priming pump. Background Art

[0002] Due to the characteristics of nitrates, denitrification is required during winter salt extraction. This requires the use of equipment related to salt removal pipelines. This equipment includes a flow aspirator, a water distribution pump, and a centrifugal pump, which together form the primary power source for denitrification. This requires the installation of multiple pieces of equipment, which is a significant workload. Furthermore, the centrifugal pump is relatively far from the salt water, resulting in a relatively weak power source. Utility Model Content

[0003] The denitrification self-priming pump proposed by the utility model aims to reduce the installation of equipment, reduce the workload, and provide greater power.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] The denitrification self-priming pump includes an extended pump body, the top of the extended pump body is fixedly connected to a drive assembly, the outside of the drive assembly is fixedly connected to an extended pump shaft, the bottom of the extended pump shaft is fixedly connected to pump blades, the bottom of the extended pump body is fixedly connected to a pump hub, the outer right side of the pump hub is fixedly connected to a discharge port, and the bottom of the pump hub is fixedly connected to a feed port.

[0006] Furthermore, the driving assembly includes a motor, the bottom of the motor is fixedly connected to the top of the extended pump body, and the output end of the motor is fixedly connected to the top of the extended pump shaft.

[0007] Furthermore, the extended pump body is integrally formed.

[0008] Furthermore, the extended pump body and the extended pump shaft are made of corrosion-resistant materials.

[0009] The utility model has the following beneficial effects:

[0010] In the utility model, the pump blades at the bottom of the extended pump shaft are driven by the motor to rotate, and the material at the bottom feed port is discharged from the discharge port. Since the extended pump body extends into the bottom of the brine, the brine enters from the feed port and is discharged from the discharge port when the extended pump shaft rotates. Since the power drive unit is arranged below the brine liquid level, the bottom of the extended pump shaft is in direct contact with the brine, and thus has a strong driving force on the brine. At the same time, since the denitrification self-priming pump no longer requires additional peripherals for assisting matching, the installation of equipment is reduced.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Reference Figure 1-Figure 3 , the utility model provides an embodiment: a denitrification self-priming pump, including an extended pump body 2, which is the main part of the denitrification self-priming pump and is usually made of corrosion-resistant materials to ensure long-term stable operation in a chemical environment. The feature of its extended design helps to increase the suction and discharge capacity of the pump, while reducing the risk of clogging of the pump. The top of the extended pump body 2 is fixedly connected to a drive assembly, and the outside of the drive assembly is fixedly connected to an extended pump shaft 3. This structure ensures that the motor 1 can effectively transmit power to the pump blades 5, driving them to rotate to produce a fluid pumping effect. The drive assembly includes a motor 1, and usually an AC or DC with appropriate power is selected to meet the operating requirements. The original 30 kW motor is changed to a 15 kW motor shown in 1 and connected to the denitrification self-priming pump body. Its bottom is fixedly connected to the top of the extended pump body 2 to firmly support and transmit power. The bottom of the motor 1 is fixedly connected to the top of the extended pump body 2. The output end of the motor 1 is fixedly connected to the top of the extended pump shaft 3. The bottom of the extended pump shaft 3 is fixedly connected with pump blades 5, which effectively draw the fluid from the feed port 7 and pass through the pump body, and finally discharge it from the discharge port 6. The shape and number of pump blades 5 will be optimized according to the specific application and fluid properties. The bottom of the extended pump body 2 is fixedly connected with a pump hub 4, which is intended to facilitate the connection of pipelines and adjust the flow direction of the fluid, ensuring that the fluid can smoothly enter and discharge the pump body. The outer right side of the pump hub 4 is fixedly connected with a discharge port 6, which is used to output the fluid processed by the pump body to the downstream pipeline or equipment. The bottom of the pump hub 4 is fixedly connected with a feed port 7, which is used to introduce the fluid or material to be processed. These fluids are pumped out by the action of the pump blades 5.

[0018] Compared with some devices in the prior art, the above content drives the pump blades 5 at the bottom of the extended pump shaft 3 to rotate through the motor 1, and discharges the material from the bottom feed port 7 from the discharge port 6.

[0019] Working Principle: First, once the pond is filled with water, the denitrification self-priming pump can be activated. After motor 1 is started, its output transmits power through the extended pump shaft 3, driving the pump blades 5 at the bottom of the pump body to rotate. As the pump blades 5 rotate, they create a low-pressure zone within the pump body, forcing the fluid or material to be treated into the pump through the feed port 7 at the bottom of the pump body. After entering the pump body, the fluid is pushed upward to the discharge port 6 as the pump blades 5 rotate. The fluid is discharged from the discharge port 6 into the downstream pipeline.

[0020] Since the extended pump body extends into the bottom of the brine, the brine enters from the feed port and is discharged from the discharge port when the extended pump shaft rotates. Since the power drive unit is set below the brine liquid level, the bottom of the extended pump shaft directly contacts the brine, so it has a strong driving force on the brine. At the same time, since the denitrification self-priming pump no longer requires additional peripherals for auxiliary matching, the installation of equipment is reduced.

[0021] Throughout the process, the corrosion-resistant material of the pump body ensures long-term stable operation of the equipment in a chemical environment, while the self-priming characteristics of the pump simplify operation and reduce pre-startup preparations.

[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
