Description

Circulating pump shaft for particle size analyzer

Technical Field

The invention relates to a pump shaft, in particular to a circulating pump shaft for a particle size analyzer.

Background

The bearing below the pump shaft of the existing particle size analyzer must be above the water level (otherwise easily damaged and unable to operate), so that the lower shaft is too long and easily deformed, and has poor stability during rotation.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a sample cell for a particle size analyzer, which can effectively prevent liquid in the sample cell from rotating, enable a sample to be more easily dispersed, break the rotating balance by deviating from the center by 5mm, effectively prevent large particles from depositing and is beneficial to the detection effect of the particle size analyzer, aiming at the defects of the prior art.

In order to solve the technical problems, the invention adopts the following technical scheme:

a circulating pump shaft for a particle size analyzer comprises a shaft, an upper rolling bearing, a lower rolling bearing, a bearing seat, a bearing baffle cover, a sealing sleeve, a sealing baffle plate and two O-shaped sealing rings.

The sealing sleeve is cylindrical, the top of the sealing sleeve is of an opening structure, and the bottom of the sealing sleeve is provided with a shaft hole and an O-shaped sealing ring hole which are communicated.

Go up antifriction bearing and antifriction bearing setting down on the bearing frame, go up antifriction bearing and the middle part of axle is located to antifriction bearing cover down, and bearing shield sets up in the bottom of bearing frame, and the axle mount sets up at the top of bearing frame, and the lower part of bearing frame is located to the seal cover, and the seal cover is fixed in epaxially through two O type sealing washer and seal baffle, and two O type sealing washers are downthehole in the O type sealing washer, and the top cover of axle is equipped with synchronous pulley.

In one embodiment, the end of the shaft fixing frame far away from the shaft is provided with a circulating motor seat.

The invention has the advantages and beneficial effects that:

1. the sealing sleeve is waterproof, and after the sealing sleeve is added, the lower rolling bearing can be inserted into water, so that the rotation of the shaft is more stable, and the rotation of the sealing sleeve in the water can drive the water to rotate, so that the dispersion of a sample is accelerated, and the detection effect of a particle size analyzer is facilitated.

2. The design of the two O-shaped sealing rings of the invention plays a role in sealing, and simultaneously, the sealing sleeve can be fixed on the shaft.

Detailed Description

In order to facilitate an understanding of the invention, a full description thereof will be given below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "disposed" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example 1

Referring to fig. 1 to 6, a circulating pump shaft for a particle size analyzer includes a shaft 1, an upper rolling bearing 2, a lower rolling bearing 3, a bearing seat 4, a bearing blocking cover 5, a sealing sleeve 6, a sealing baffle 7, two O-rings 8, a synchronous pulley 9, and a shaft fixing frame 10.

The sealing sleeve 6 is cylindrical, the top of the sealing sleeve 6 is of an opening structure, and the bottom of the sealing sleeve 6 is provided with a shaft hole 11 and an O-shaped sealing ring hole 12 which are communicated.

Specifically, an upper rolling bearing 2 and a lower rolling bearing 3 are provided on a bearing housing 4. The upper rolling bearing 2 and the lower rolling bearing 3 are sleeved in the middle of the shaft 1. The bearing shield cover 5 is arranged at the bottom of the bearing seat 4. A shaft mount 10 is provided on top of the bearing block 4. The sealing sleeve 6 is sleeved on the lower part of the bearing seat 4, and the sealing sleeve 6 is fixed on the shaft 1 through two O-shaped sealing rings 8 and a sealing baffle 7. Two O-shaped sealing rings 8 are arranged in the O-shaped sealing ring hole 12. The top of the shaft 1 is sleeved with a synchronous pulley 9.

Wherein, the end of the shaft fixing frame 10 far away from the shaft 1 is provided with a circulating motor seat 13.

The invention has the advantages and beneficial effects that:

1. the sealing sleeve 6 is waterproof, and after the sealing sleeve 6 is added, the lower rolling bearing 3 can be inserted into water, so that the shaft 1 rotates more stably, and the sealing sleeve 6 can drive the water to rotate when rotating in the water, so that the dispersion of a sample is accelerated, and the detection effect of a particle size analyzer is facilitated.

2. The design of the two O-shaped sealing rings 8 plays a role in sealing, and simultaneously, the sealing sleeve 6 can be fixed on the shaft 1.

The above-mentioned embodiments only express one embodiment of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
