Description

Technical Field

[0001] The present technical solution relates to the field of mixers, particularly to the field of discharging devices, and specifically refers to a cylinder position detection device. Background Art

[0002] In existing mixers, the discharging device generally uses a cylinder to push the discharging valve. During the mixing operation, the discharging valve is in a closed state. When discharging is required, the solenoid valve controls the cylinder to actuate and open the discharging valve. At this time, the stirring blades are opened for the discharging operation. After the discharging is completed, the solenoid valve controls the cylinder to push the discharging door to close and proceed to the next process. To prevent the discharging door from opening or closing incompletely, a magnetic switch is usually configured to detect the opening and closing position of the discharging door. When the discharging door is not in place, an alarm is given and the machine operation is stopped. In practical applications, when the mixed material is explosive powder, an explosion-proof magnetic switch is also required for the magnetic switch. Currently, cylinder suppliers cannot provide explosion-proof magnetic switches or the explosion-proof grade does not meet the requirements.

[0003] In addition, due to the influence of the wall thickness of the cylinder body itself, the magnetic induction intensity outside the cylinder body of the existing cylinder with a built-in magnetic ring is very low. The proximity switch corresponding to the explosion-proof specification generally uses mechanical contacts, has high explosion-proof requirements, the permanent magnet of the induction part needs to be encapsulated, and the magnetic induction intensity is also very low.

[0004] Based on this, it is necessary to propose a discharging device that can preferably meet the explosion-proof specification requirements to meet the actual needs. Summary of the Utility Model

[0007] The cylinder position detection device is mainly characterized in that the device includes:

[0008] A cylinder with an internal magnetic ring, a mounting bracket arranged on the cylinder, the top of the mounting bracket is used to mount an explosion-proof proximity switch, and the explosion-proof proximity switch is conducted through the magnetism of the magnetic substance and spring installed at the lower part, so as to realize the position detection of the cylinder during the discharging process.

[0009] Preferably, the magnetic substance is a powerful magnetic ring, and the powerful magnetic ring is arranged on the powerful magnetic ring mounting seat through powerful magnetic ring mounting screws.

[0010] Preferably, a guiding bracket is arranged at the lower part of the mounting bracket, and a screw hole is arranged at the middle position of the guiding bracket. The upper part of the screw hole is used to insert a countersunk head screw.

[0011] Preferably, the springs are arranged on the left and right sides of the guiding bracket, and the guiding bracket realizes balanced support through symmetrically arranged pin shafts.

[0012] Preferably, an explosion-proof proximity switch mounting nut is further arranged on the explosion-proof proximity switch. The explosion-proof proximity switch is fixedly mounted on the mounting bracket through the explosion-proof proximity switch mounting nut and is in contact with the countersunk head screw.

[0013] Preferably, the spring is elastically arranged on the pin shaft of the guiding bracket and realizes elastic compression through the magnetic substance.

[0036] In order to more clearly describe the technical content of the present utility model, the following will be further described in conjunction with specific embodiments.

[0037] Before detailing the embodiments according to the present utility model, it should be noted that in the following text, the term "comprising", "including" or any other variant is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not explicitly listed, or elements inherent to such process, method, article or device.

[0038] Please refer to Figure 1 As shown, the cylinder position detection device of the present utility model, wherein, the device includes:

[0039] A cylinder 1 with an internal magnetic ring, a mounting bracket 5 arranged on the cylinder 1, the top of the mounting bracket 5 is used to mount an explosion-proof proximity switch 7, and the explosion-proof proximity switch 7 is conducted through the magnetic substances installed at the lower part and the magnetism of a spring 4, so as to realize the position detection of the cylinder 1 during the discharging process.

[0040] As a preferred implementation manner of the present utility model, the magnetic substance is a strong magnetic ring 13, and the strong magnetic ring 13 is arranged on a strong magnetic ring mounting seat 11 through strong magnetic ring mounting screws 14.

[0041] As a preferred implementation manner of the present utility model, a guide bracket 9 is arranged at the lower part of the mounting bracket 5, and a screw hole is arranged at the middle position of the guide bracket 9, and the upper part of the screw hole is used to insert a countersunk head screw 10.

[0042] As a preferred implementation manner of the present utility model, the spring 4 is arranged on the left and right sides of the guide bracket 9, and the guide bracket 9 realizes balanced support through symmetrically arranged pin shafts 3.

[0043] As a preferred embodiment of the present utility model, an explosion-proof proximity switch mounting nut 8 is further provided on the explosion-proof proximity switch 7. The explosion-proof proximity switch 7 is fixedly mounted on the mounting bracket 5 through the explosion-proof proximity switch mounting nut 8 and is in contact with the countersunk head screw 10.

[0044] As a preferred embodiment of the present utility model, the spring 4 is elastically arranged on the pin shaft 3 of the guiding bracket 9 and is elastically compressed by the magnetic substance.

[0045] The working principle of the cylinder position detection device of this technical solution is as follows:

[0046] When the cylinder magnetic ring approaches the magnet, the magnets repel each other to generate a magnetic force to push the magnet and related components upward. After rising, the magnetic object attracts the magnetic switch contact to descend, thus conducting; when the cylinder magnetic ring moves away from the magnet, the magnetic substance is pushed away by the elastic force of the spring, and the magnetic switch is not conducted (the force after the spring is compressed can just push away the magnetic substance and the magnetic switch. The distance between the magnetic substance and the magnetic switch is adjusted by the thread, so as to adjust the attraction between the magnetic switch and the magnetic object, that is, the smaller the distance, the greater the attraction).

[0047] By adopting the cylinder position detection device of the present utility model, through the attraction and repulsion between the magnets, it can effectively meet the requirements of the explosion-proof grade or provide a magnetic switch with the required explosion-proof specifications, thus effectively solving the explosion-proof problem.

[0048] In this specification, the present utility model has been described with reference to its specific embodiments. However, it is obvious that various modifications and transformations can still be made without departing from the spirit and scope of the present utility model. Therefore, the specification and the drawings should be regarded as illustrative rather than restrictive.
