Description

Technical Field

[0001] This utility model belongs to the field of metal particle detection, and in particular relates to a metal abrasive sensor. Background Technology

[0002] A sensor is a detection device that can sense the measured information and transform it into an electrical signal or other required form of information output according to a certain rule to meet the requirements of information transmission, processing, storage, display, recording and control. Metal abrasive sensors are a type of sensor that can detect the presence and outer diameter of metal particles in a medium. However, with existing metal abrasive sensors, if there are many metal particles in the medium with varying outer diameters, the detected electrical signal is relatively noisy and mottled due to the influence of the sensor's detection accuracy, which affects the detection quality. Summary of the Invention

[0003] In view of this, the present invention aims to propose a metal abrasive sensor to solve the problem that the existing sensors are affected by the detection accuracy, resulting in noisy and mottled electrical signals that affect the detection quality.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A metal abrasive sensor includes a housing and a feed tube concentrically arranged within its inner ring. A mounting base is sleeved around the feed tube and located within the inner ring of the housing. The mounting base has multiple mounting grooves along its axial direction. Each mounting groove contains an independently wound detection unit, and each detection unit includes multiple detection lines arranged parallel to each other. Each detection line is spirally wound within the mounting groove.

[0005] Furthermore, a protective tube is fitted around the mounting groove, and the protective tube has two wire holes. The two ends of the detection wire pass through one of the wire holes and are then connected to the outside.

[0006] Furthermore, each end of the outer shell is detachably connected to an end cap, and a pressing platform is provided on one side of each end cap, with the outer edge of one end of the pressing platform abutting against the inner ring of the protective tube.

[0007] Furthermore, the pressing platform is a hollow frustum structure.

[0008] Furthermore, an adapter tube is provided at one end of the pressure plate, and the outer periphery of the adapter tube is located within the inner ring of the protective tube. The inner ring of the adapter tube is sealed to the outer periphery of the feed tube through a sealing ring.

[0009] Furthermore, the inner ring of the adapter tube is provided with a retaining ring, one side of which abuts against one end of the feed tube.

[0010] Furthermore, the end cap has a threaded hole in the middle, and the feed nozzle is threadedly connected to the threaded hole.

[0011] Compared with the prior art, the metal abrasive sensor of this utility model has the following advantages: (1) The metal abrasive sensor described in this utility model has multiple parallel detection coils that can work together on the medium to be detected in the feed tube, which can improve the detection accuracy, reduce the outer diameter of the detected particles, make the detected electrical signal clear and easy to distinguish, and improve the detection quality.

[0012] (2) In order to protect the detection coil in the mounting slot, a protective tube is installed around the mounting slot. The protective tube has two wire holes. The two ends of the detection wire pass through one wire hole and are connected to the external controller. By setting the protection, the detection coil can be protected, prevented from being contaminated by dust, improve the service life of the device, and reduce maintenance costs.
