Description

Technical Field

[0001] The utility model relates to the technical field of pump equipment, in particular to a pump body with a ceramic lining. Background Art

[0002] Ceramic linings are primarily made of alumina, supplemented by other ingredients, and sintered at 1700°C. They are widely used in coal conveying, material handling, pulverizing, ash removal, and dust removal systems, among other high-wear machinery and equipment in thermal power, steel, smelting, machinery, coal, mining, chemical, cement, and port terminals. Different types of products can be selected based on specific needs. Ceramic linings, due to their high hardness, can extend the life of pump casings. However, this high hardness results in low toughness and brittleness, making them easily shattered by external forces. This can lead to ceramic liners being prone to breakage within pumps.

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0022] like Figures 1 to 3 As shown, a pump body 1 with a ceramic lining 2 according to an embodiment of the present invention comprises: a pump body 1, a ceramic lining 2 and a fixing assembly;

[0023] The pump body 1 has a pump cavity therein, and the ceramic lining plate 2 is arranged on the inner wall of the pump cavity;

[0024] The fixing assembly includes: a fastener 3, a soft extrusion part 5 and an anti-collision part 6;

[0025] The fastener 3 is used to connect the inner wall of the pump chamber with the ceramic lining 2. The soft extrusion part 5 is arranged between the fastener 3 and the soft extrusion part 5. The soft extrusion part 5 is used to reduce the pressure of the fastener 3 on the ceramic lining 2. The anti-collision part 6 is sleeved on the outside of the fastener 3. The anti-collision part 6 is used to buffer the collision force between the fastener 3 and the ceramic lining 2.

[0026] The fastener 3 of the present application fixes the ceramic lining 2 on the inner wall of the pump chamber, and the soft extrusion component 5 prevents the pressure of the fastener 3 from directly acting on the ceramic lining 2, thereby reducing the pressure of the fastener 3 on the ceramic lining 2, and the anti-collision component 6 buffers the impact force of the collision between the fastener 3 and the ceramic lining 2, thereby preventing the ceramic lining 2 from being broken.

[0027] like Figure 3~Figure 4 As shown, the fastener 3 includes: a threaded portion 31, a polished rod portion 32 and a nut portion 33;

[0028] The smooth rod portion 32 is located between the threaded portion 31 and the nut portion 33. The diameter of the smooth rod portion 32 is larger than the diameter of the threaded portion 31, and the diameter of the smooth rod portion 32 is smaller than the diameter of the nut portion 33. The threaded portion 31 is inserted into the inner wall of the pump body 1, and the smooth rod portion 32 and the nut portion 33 are both located in the ceramic lining 2.

[0029] The fastener 3 can be rotated by the nut portion 33, and the nut portion 33 is inserted into the inner wall of the pump body 1 to connect the ceramic liner 2 to the pump body 1. In this embodiment, the fastener 3 is a shoulder screw.

[0030] like Figure 3~Figure 4 As shown, the soft extrusion member 5 is sleeved on the polished rod portion 32 , and the soft extrusion member 5 is located between the ceramic liner 2 and the nut portion 33 . The soft extrusion member 5 is used to reduce the pressure of the nut portion 33 on the ceramic liner 2 .

[0031] The soft extrusion member 5 is made of elastic material, and generates a rebound force on the ceramic lining plate 2 after being squeezed by an external force.

[0032] After the ceramic lining 2 is connected to the pump body 1 by the fastener 3, there is a gap between the nut part 33 of the fastener 3 and the ceramic lining 2. The thickness of the soft extrusion 5 is greater than this gap. By placing the soft extrusion 5 in this gap, the soft extrusion 5 will generate a rebound force on the ceramic lining 2 after being squeezed by an external force, and the ceramic lining 2 can be fixed by the rebound force.

[0033] like Figures 1 to 3 As shown, the anti-collision member 6 is cylindrical and is sleeved on the outside of the polished rod portion 32 . The anti-collision member 6 is located between the ceramic liner 2 and the polished rod portion 32 .

[0034] When the pump chamber rotates, the ceramic lining 2 will undergo rotational displacement. By setting the anti-collision part 6 between the ceramic lining 2 and the light rod part 32, the ceramic lining 2 can be prevented from colliding with the fastener 3, and the impact force between the ceramic lining 2 and the fastener 3 can be buffered, thereby preventing the ceramic lining 2 from being broken.

[0035] like Figure 3 As shown, a buffer plate 4 is provided between the pump body 1 and the ceramic lining plate 2, and the buffer plate 4 is used to buffer the impact force of the collision between the pump body 1 and the ceramic lining plate 2. The thickness of the buffer plate 4 is 0.1mm-0.4mm.

[0036] The impact force between the ceramic lining plate 2 and the inner wall of the pump chamber is buffered by the buffer plate 4 to prevent the ceramic lining plate 2 from being broken.

[0037] Above, refer to Figures 1 to 4 A pump body 1 with a ceramic lining 2 according to an embodiment of the utility model is described. The fastener 3 of the present application fixes the ceramic lining 2 on the inner wall of the pump chamber. The soft extrusion component 5 is used to prevent the pressure of the fastener 3 from directly acting on the ceramic lining 2, thereby reducing the pressure of the fastener 3 on the ceramic lining 2. The anti-collision component 6 buffers the impact force of the collision between the fastener 3 and the ceramic lining 2, thereby preventing the ceramic lining 2 from being broken.
