Technical Field

[0001] This utility model relates to the technical field of sanitary pumps, specifically a sanitary pump. Background Technology

[0002] Sanitary pumps are classified according to their application, specifically those used for conveying products that come into contact with the human body, such as pharmaceuticals, dairy products, beverages, food, cosmetics, food additives, and fine chemicals.

[0003] For example, a sanitary pump with authorization announcement number "CN212536038U" solves the problem of existing sanitary pumps causing trouble and increasing workload during transportation. The aforementioned pump uses an integral molding of the fixing part and bottom end, and the lifting rod and top end, which greatly improves the stability of the fixing part and bottom end, and the lifting rod and top end, allowing for integrated transportation. However, existing sanitary pumps have sliding components including a first crossbar, protrusion, support part, and other interconnected parts. The rotating part is connected to the crossbar through a through hole, and the support part also has a threaded limit rod. These component connections are complex. When maintenance is required, disassembling and reassembling these interconnected structures is cumbersome, and the high precision required for the fit of each component increases the difficulty of maintenance, making it inconvenient.

[0006] In this design, the impeller is made of special plastics (such as PTFE and PEEK) to meet the requirements of acid and alkali resistance and non-toxicity.

[0007] Preferably, the connecting mechanism includes a housing, which is threadedly connected to the outer wall of the motor by bolts, and the end of the housing is threadedly connected to the pump body by bolts.

[0011] Preferably, the mounting mechanism includes a clamp, which is threadedly connected to the housing by bolts, the lower end of the clamp is fixedly connected to the fixing seat, and the outer wall of the fixing seat is fixedly connected to the rubber pad.

[0012] The clamps and mounting base in this installation mechanism work together to stably install the sanitary pump in the designated position, while the rubber pads reduce vibration and noise generated during equipment operation.

[0013] Preferably, the output terminal of the electrical connector is electrically connected to the motor.

[0014] This setting ensures the electrical connection between the connector and the motor, guaranteeing normal motor startup and operation control.

[0015] Preferably, the upper end of the fixed base is threadedly connected to the motor by bolts, and the output shaft of the motor is rotatably connected to the housing by bearings.

[0016] This feature further strengthens the connection between the motor and the mounting mechanism, preventing loosening due to prolonged operation and improving the overall stability and reliability of the structure.

[0017] Preferably, the inner wall of the fixing seat is machined with fixing holes.

[0018] The inclusion of mounting holes in this feature provides multiple mounting options, enhancing the adaptability of the sanitary pump in various working scenarios.

[0019] The sanitary pump proposed in this utility model has the following advantages: the connection mechanism uses a sleeve and pump body bolted together to enhance the sealing performance; the sleeve and pump body are made of 316L stainless steel and mirror polished to prevent microbial adhesion and facilitate cleaning and sterilization; the rubber pad of the installation mechanism reduces vibration and noise; the fixing hole improves the adaptability of the scene; the flange connection to the outside enhances the sealing performance; the overall structure is stable; and the sleeve, pump body and each part of the sleeve can be disassembled in sections using bolts, making maintenance more convenient.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] Please see Figure 1-6 In this embodiment, a sanitary pump includes a motor 1 and a coupling 2. The output shaft of the motor 1 is threadedly connected to the coupling 2 by bolts. An electric coupler 3 is installed on the outer wall of the motor 1. The outer wall of the coupling 2 is fixedly connected to the pump shaft 4. The end of the pump shaft 4 is fixedly connected to the impeller 5. A connecting mechanism 6 is connected to the outer wall of the motor 1.

[0029] The connecting mechanism 6 includes a housing 601, which is threadedly connected to the outer wall of the motor 1 by bolts. The end of the housing 601 is threadedly connected to the pump body 602 by bolts. The upper end of the pump body 602 is machined with an outlet 603, and the side end of the pump body 602 is machined with an inlet 604.

[0030] The connecting mechanism 6 is bolted to the pump body 1 using the housing 601 to enhance sealing. The housing 601 and the pump body 602 are made of 316L stainless steel and are mirror polished to prevent microbial adhesion and facilitate cleaning and sterilization. The rubber gasket 803 of the mounting mechanism 8 reduces vibration and noise. The fixing hole 9 improves the adaptability of the scene. The flange 7 connects to the outside to enhance sealing. The overall structure is stable. The housing 601, the pump body 1 and each part of the housing 601 can be disassembled in sections using bolts, making maintenance more convenient.

[0031] The upper end of the outlet 603 is threadedly connected to the flange 7 by bolts. The outer wall of the housing 601 is connected to the mounting mechanism 8, which includes a clamp 801. The clamp 801 is threadedly connected to the housing 601 by bolts. The lower end of the clamp 801 is fixedly connected to the fixing seat 802. The outer wall of the fixing seat 802 is fixedly connected to the rubber pad 803.

[0032] The output end of the electric connector 3 is electrically connected to the motor 1. The upper end of the fixed base 802 is threadedly connected to the motor 1 by bolts. The output shaft of the motor 1 is rotatably connected to the housing 601 by bearings. The inner wall of the fixed base 802 is machined with a fixing hole 9.

[0033] Working principle:

[0034] First, bolts are threaded through the fixing holes 9 on the fixing seat 802 to connect with the external components, thus positioning the fixing seat 802. Then, the clamp 801 is bolted to the housing 601, firmly securing the main structure of the entire sanitary pump. The rubber pad 803 acts as a buffer and anti-slip agent during installation, preventing displacement due to vibration. The motor 1 is then bolted to one side of the housing 601. A sealed bearing is installed between the housing 601 and the output shaft of the motor 1. Finally, the connecting shaft 2 is connected to the motor... After the output shaft is threaded, the pump body 602 is bolted to the casing 601, sealing the pump body 602 around the impeller 5. Power is connected via the electrical connector 3, and the motor 1 starts. Its output shaft drives the coupling 2 to rotate, which in turn drives the pump shaft 4 and impeller 5 to rotate at high speed inside the pump body 602. At this time, the fluid to be transported enters the pump body 602 through the inlet 604. Under the centrifugal force of the impeller 5, the fluid is pressurized and then transported out through the outlet 603 via the flange 7 and external pipeline. Throughout the operation, the casing 601 effectively protects the internal components such as the pump shaft 4, preventing external impurities from affecting equipment operation. Simultaneously, the 316L stainless steel casing 601 and pump body 602, along with their mirror-finish surface treatment, ensure hygiene and safety during fluid transport, meeting the stringent hygiene standards of the pharmaceutical and food industries. The bearing configuration ensures the flexibility and stability of rotation between the output shaft of motor 1 and housing 601, reducing frictional losses during operation and extending the service life of the equipment. When cleaning or maintenance is required, the internal components can be easily inspected and cleaned by removing the bolts between housing 601 and motor 1, pump body 602, and connecting bolts between flange 7 and outlet 603. The operation is simple and convenient, improving the maintenance efficiency of the equipment.
