Description

Technical Field

[0001] The utility model relates to the technical field of disc-type separators, in particular to a nozzle for a disc-type separator. Background Art

[0002] Disc separator is a high-speed sedimentation centrifuge. It can quickly and effectively separate liquids from solids, or mixtures of two immiscible liquids and solids, by using high speed and strong centrifugal force. Due to its high separation efficiency, it is widely used in industries such as shipping, food, medicine, chemical industry, textile and environmental protection.

[0003] A nozzle-type disc separator is a type of disc separator suitable for materials with relatively high impurity content and uniform particle size. Impurities are continuously discharged through nozzles in a nozzle-type disc separator, creating a high load during the separation process. Typically, the drum is equipped with 4 to 12 nozzles, each with a diameter of 1mm-2mm, evenly distributed across the drum. Due to the strong and continuous impact of impurities in the material, the nozzles have a limited service life and are consumable parts requiring frequent replacement. Conventional nozzles are integrated components, making frequent replacement expensive.

[0004] Specific as Figure 1 As shown, Figure 1 The figure is a schematic diagram of the original traditional nozzle. The nozzle seat (12) is fixed on the outer wall of the drum body (11) of the separator. A sealing ring (16) is installed on the nozzle seat. The nozzle core (14) is made of hard alloy material and is embedded in the nozzle valve (13). The two are integrated and installed in the nozzle seat. A sealing ring (15) is installed on the nozzle valve. The separated impurities are sprayed out from the nozzle valve hole through the nozzle core. Since the nozzle valve and the nozzle core are integrated, when the nozzle core and the nozzle valve need to be replaced after being worn, the entire nozzle valve and the nozzle core need to be replaced. Utility Model Content

[0005] The purpose of the utility model is to address the problem of high use cost of existing disc separator nozzles and provide a disc separator nozzle that only requires replacing a small number of parts when replacing the nozzle, thereby reducing the use cost.

[0006] In order to achieve the above purpose, the technical solution of the utility model is to design a nozzle for a disc separator, which includes

[0007] The nozzle seat is installed on the outer wall of the separator's drum;

[0008] A nozzle valve is installed in the nozzle seat, and a mounting groove is provided on the outer side of the nozzle valve;

[0009] The nozzle valve core is detachably installed in the nozzle valve, and a hole is provided at the small end of the nozzle valve core;

[0010] The nozzle body is detachably mounted in the mounting groove on the nozzle valve;

[0011] The nozzle core has a through hole at its center, the nozzle core is embedded in the nozzle body, and the through hole of the nozzle core is communicated with the hole on the nozzle valve core.

[0012] Furthermore, the nozzle core and the nozzle body are integrally formed.

[0013] Furthermore, the inner wall of the installation groove is provided with a thread, the outer periphery of the nozzle body is provided with a thread adapted to the inner wall of the installation groove, and the nozzle body is screwed into the installation groove on the nozzle valve through the thread.

[0014] Furthermore, a nozzle pad is installed between the nozzle body and the nozzle valve.

[0015] Furthermore, a tapered hole is provided in the center of the nozzle valve core, and the hole is connected to the small end of the tapered hole.

[0016] Furthermore, a first sealing ring is installed on the outer peripheral wall of the nozzle valve core, and the first sealing ring is located between the nozzle valve and the nozzle valve core.

[0017] Furthermore, the first sealing ring is arranged at the large end of the nozzle valve core.

[0018] Furthermore, the nozzle core is made of cemented carbide material.

[0019] Furthermore, a second sealing ring is installed on the outer peripheral wall of the nozzle seat, and the second sealing ring is arranged between the drum body and the nozzle seat.

[0020] Furthermore, a third sealing ring is installed on the outer peripheral wall of the nozzle valve, and the third sealing ring is installed between the nozzle seat and the nozzle valve.

[0021] The advantages and benefits of this utility model are that the nozzle core and nozzle valve core are the most susceptible to wear in a nozzle separator. If the nozzle core needs to be replaced due to wear, only the nozzle body and nozzle core need to be replaced. If the nozzle valve core is worn, only the nozzle valve core needs to be replaced. When replacing the nozzle of a disc separator using this nozzle, only a small number of parts need to be replaced, which can reduce production costs. BRIEF DESCRIPTION OF THE DRAWINGS
