Abstract
The invention relates to a novel slurry-pump overcurrent device. The novel slurry-pump overcurrent device is composed of a sheath, a rear protective plate and a front protective plate, wherein the left side and the right side of the middle of the sheath are respectively provided with a socket, the rear protective plate is arranged in the socket in the left side of the sheath, the front protective plate is arranged in the socket is the right side of the sheath, the sheath, the rear protective plate and the front protective plate are respectively formed by a three-layer structure in a combined mode, a steel frame is arranged on each outer layer, a ceramic lining is arranged on each inner layer, and a protective layer made of high-molecular material is arranged between each steel frame and the corresponding ceramic lining. The novel slurry-pump overcurrent device has the advantages of being high in abrasion resistance, long in service life and low in production cost, and is suitable for being popularized and used in the technical field of slurry pumps.
Description
Technical field
The present invention relates to a kind of Novel slurry pump overflow means, belong to slag stock pump accessory technical field.
Background technique
Slag stock pump is the one of centrifugal pump, is widely used in the industries such as mine, electric power, metallurgy, coal, environmental protection, for delivery of a kind of special device that contains abrasion solid particle or body refuse.According to statistics, there is the slag stock pump of 80% left and right for mine industry, because slag stock pump is in conveying slag and mud process, working environment is more severe, and in the ore pulp fluid of carrying, the particle of slag is large, impact force is strong, and the lift of fluid is high, flow is large, and workload is large, therefore, overflow means wearing and tearing to slag stock pump are very serious, spoilage is higher, has greatly shortened the working life of slag stock pump, affects working efficiency.
The overflow means of existing slag stock pump is to adopt high-chromium abrasion-proof cast iron casting to form, because high-chromium abrasion-proof cast iron is noble metal material, expensive, damages rear unrepairable, has greatly increased the cost of production of enterprise.Therefore, develop that wear resistance is strong, long service life, the overflow means of long-lived slag stock pump, is slag stock pump industry technology personnel technical barriers urgently to be resolved hurrily.
Summary of the invention
The object of the invention is for a kind of Novel slurry pump overflow means is provided, the backplate of this slag stock pump overflow means and sheath all adopt three-decker to combine, in its three-decker, in, outer three-decker adopts respectively pottery, macromolecular material, steel are made, because ceramic hardness is large, wear-resisting property is strong, can extend the working life of slag stock pump overflow means, adopt macromolecular material as intermediate protective layer, can solve the frangible drawback of easily splitting of pottery, adopt steel to make the external frame of Steel Skeleton as slag stock pump overflow means, can strengthen the intensity of slag stock pump overflow means, this slag stock pump overflow means has that wear-resisting property is strong, long service life, feature that cost of production is low, is adapted at slag stock pump technical field and promotes the use of.
In order to achieve the above object, the present invention realizes by following technological means:
A kind of Novel slurry pump overflow means; it is comprised of sheath, rear backplate, apron plate part; the left and right sides, sheath middle part is provided with socket; in the socket of sheath left side, be provided with rear backplate; in the socket of sheath right side, be provided with apron plate, it is characterized in that: described sheath, rear backplate, apron plate combine by three-decker, and skin is provided with Steel Skeleton; internal layer is provided with ceramic-lined, Steel Skeleton and ceramic-lined between be provided with macromolecular material protective layer.
Described macromolecular material protective layer is used polyurethane or rubber to make.
The present invention mainly has following beneficial effect:
The backplate of this slag stock pump overflow means and sheath all adopt three-decker to combine, interior, the domestic and abroad three-decker of its three-decker adopts respectively pottery, macromolecular material, steel to make, because ceramic hardness is large, wear-resisting property is strong, can extend the working life of slag stock pump overflow means, adopt macromolecular material as intermediate protective layer, can solve the frangible drawback of easily splitting of pottery, adopt steel to make the external frame of Steel Skeleton as slag stock pump overflow means, can strengthen the intensity of slag stock pump overflow means; This slag stock pump overflow means has that wear-resisting property is strong, long service life, feature that cost of production is low, is adapted at slag stock pump technical field and promotes the use of.
