Technical Field

[0001] This utility model relates to the field of slurry pump technology, specifically a low-noise, wear-resistant slurry pump. Background Technology

[0002] A slurry pump is a centrifugal pump that uses the centrifugal force of an impeller to enable the flow of a solid-liquid mixture. It is mainly used in mining, power plants, metallurgy, dredging, chemical, building materials, and petroleum industries. A slurry pump typically includes a pump head structure, a bracket structure, and a shaft seal.

[0003] In the operation of slurry pumps, the conversion of potential energy and kinetic energy generates significant noise, and the pumps also vibrate, which can easily affect the surrounding environment and operators. At the same time, the rotation of the shaft and the friction of the bearings generate heat, which is difficult to cool, leading to damage and reduced lifespan of the slurry pump, thus reducing its practicality.

[0004] Therefore, this utility model provides a low-noise, wear-resistant slurry pump. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a low-noise, wear-resistant slurry pump to solve the problems mentioned in the background. This invention facilitates cooling of the slurry pump by using a first inner cavity, a second inner cavity, and a third inner cavity, along with the coolant inside them. Furthermore, the invention provides sound insulation and noise reduction for the slurry pump through shock-absorbing pads, coolant, and a soundproof cover, thus avoiding any impact on the surrounding environment and operators. It is highly practical.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a low-noise wear-resistant slurry pump, including a support, the support being T-shaped, a shaft being rotatably mounted on the top of the support via a mounting plate and a bearing, a second inner cavity and a first inner cavity being respectively opened inside the top of the support and inside the mounting plate, a liquid storage tank being opened at the bottom of the second inner cavity, a limiting groove being opened at the top of the bottom end of the support, a first pump housing being fixedly mounted on one side of the support and the mounting plate by bolts, a second pump housing being fixedly mounted on one side of the first pump housing by bolts, the bottom ends of the first and second pump housings being installed inside the limiting groove, a third inner cavity being opened inside both the first and second pump housings, and a sound insulation cover being fixedly installed on the outer side of the mounting plate.

[0008] Furthermore, soundproof covers are fixedly installed on the outer sides of both the first and second pump housings, and a flexible hose is fixedly connected between the top ends of the third inner cavity inside the first and second pump housings.

[0009] Furthermore, a connecting pipe is fixedly connected between the top end of the first inner cavity and the third inner cavity inside the first pump housing, and a flexible tube is fixedly connected between the bottom end of the third inner cavity inside the second pump housing and the second inner cavity.

[0010] Furthermore, a delivery pump is fixedly installed at the top of one end of the support, the inlet of the delivery pump is fixedly installed inside the liquid storage tank, and an addition port is fixedly installed at the top of the liquid storage tank corresponding to the front side of the support.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a low-noise, wear-resistant slurry pump that draws coolant from the inside of the storage tank using a delivery pump. The coolant is then delivered into the first inner cavity through a fixed pipe, into the third inner cavity through a connecting pipe, and finally discharged into the second inner cavity through a hose and flows back into the storage tank, facilitating circulation.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a low-noise, wear-resistant slurry pump, including a support 1, the support 1 being T-shaped, a shaft 5 rotatably mounted on the top of the support 1 via a mounting plate 4 and a bearing 18, a second inner cavity 16 and a first inner cavity 15 respectively formed inside the top of the support 1 and inside the mounting plate 4, a liquid storage chamber 13 formed at the bottom of the second inner cavity 16, a limiting groove 11 formed at the top of the bottom end of the support 1, a first pump housing 7 fixedly mounted on one side of the support 1 and the mounting plate 4 by bolts, and a shaft 5 rotatably mounted on one side of the first pump housing 7 by bolts.

By adding coolant to the first inner cavity 15, the second inner cavity 16 and the third inner cavity 20, the bearing 18, the shaft 5 and the first pump housing 7 and the second pump housing 8 can be cooled down, thereby improving the service life of the slurry pump. The combination of the sound insulation cover 21 and the coolant can effectively reduce the noise of the slurry pump and avoid affecting the surrounding environment and operators, which is highly practical.

[0022] In this embodiment, a discharge port 10 is fixedly provided at the rear end of the first pump casing 7. The discharge port 10 is located in the tangential direction of the first pump casing 7 and the second pump casing 8. A feed port 9 is fixedly provided at the center of one end of the second pump casing 8. The solid-liquid mixture can enter the interior of the slurry pump through the feed port 9 and be discharged from the discharge port 10 under the rotation of the impeller 19, which facilitates the transportation of the solid-liquid mixture.

[0023] In this embodiment, soundproof covers 21 are fixedly installed on the outer sides of both the first pump housing 7 and the second pump housing 8. A flexible tube is fixedly connected between the top ends of the third inner cavity 20 inside the first pump housing 7 and the second pump housing 8.

A flexible tube is fixedly connected between the bottom end of the third inner cavity 20 inside the second pump housing 8 and the second inner cavity 16. A delivery pump 14 is fixedly installed at the top of one end of the support 1. The inlet of the delivery pump 14 is fixedly installed inside the liquid storage tank 13. The top end of the liquid storage tank 13 corresponds to the support 1. A filling port is fixedly provided on the front side of the pump. A fixed pipe 17 is fixedly connected between the outlet of the pump 14 and the first inner cavity 15.

The pump 14 can easily draw coolant from the inside of the storage tank 13 and send it into the inside of the first inner cavity 15 through the fixed pipe 17. The coolant circulates through the connecting pipe 12, the third inner cavity 20, the hose, the second inner cavity 16 and the storage tank 13 in sequence, which can facilitate the cooling of the slurry pump. The combination of coolant and soundproof cover 21 can reduce noise transmission, which can facilitate the noise reduction of the slurry pump and has high practicality.

The shaft 5 can easily rotate through the bearing 18 and is connected to the drive motor through the coupling 6. The shaft 5 can drive the impeller 19 to rotate, which facilitates the transportation of solid-liquid mixtures.

[0025] In this embodiment, a shock-absorbing pad 2 is fixedly installed at the bottom of the support 1. Fixing holes 3 are equidistantly opened at the front and rear ends of the support 1 and the shock-absorbing pad 2. The shock-absorbing pad 2 facilitates the shock absorption of the slurry pump, and the fixing holes 3 facilitate the fixed installation of the slurry pump.

[0026] When using this low-noise, wear-resistant slurry pump, the support 1 is easily fixed by installing bolts inside the fixing hole 3. The vibration damping pad 2 reduces noise from the slurry pump. Coolant is added to the storage tank 13 through the filling port. The first pump housing 7 and the second pump housing 8 are installed sequentially and fixed to the support 1, the first pump housing 7, and the second pump housing 8 with bolts. The bottom ends of the first pump housing 7 and the second pump housing 8 are installed inside the limiting groove 11, which facilitates support for the first pump housing 7 and the second pump housing 8 and improves their stability. Pump 14 draws coolant from the inside of the storage tank 13 and sends it into the first inner cavity 15 through the fixed pipe 17, into the third inner cavity 20 through the connecting pipe 12, and finally into the second inner cavity 16 through the hose and into the storage tank 13, facilitating circulation. The first inner cavity 15, the second inner cavity 16 and the third inner cavity 20 and the coolant inside them facilitate cooling and reducing the temperature of the slurry pump. Furthermore, the vibration damping pad 2, the coolant and the sound insulation cover 21 facilitate sound insulation and noise reduction of the slurry pump, avoiding impact on the surrounding environment and operators, making it highly practical.
