Description

Technical Field

[0001] The utility model relates to the field of testing or analyzing materials by means of measuring the chemical or physical properties of the materials, in particular to an analytical ferroscope. Background Art

[0002] Lubricating oil plays an important role in equipment lubrication and wear reduction, cooling, anti-corrosion and rust prevention, noise reduction and shock absorption, and sealing and leak prevention. Especially in centralized lubrication systems, the operating status and life of mechanical equipment are closely related to the quality of lubricating oil. By testing various indicators of lubricating oil, its quality can be analyzed. Ferrography analysis technology is a lubricating oil analysis technology based on abrasive analysis. It is the most effective analysis method for equipment wear status monitoring and fault diagnosis. It has achieved remarkable results in timely predicting equipment wear and failure hazards, identifying the causes and locations of equipment failures, providing a reliable basis for equipment inspection and maintenance, and ensuring the safe operation of equipment.

[0003] The Chinese utility model patent with the authorization announcement number CN217474362U discloses a ferroscope, which has a thistle-shaped glass tube, i.e., a thistle tube, installed on the ferroscope support that can rotate around a vertical axis. The thistle tube includes a holding cavity for holding sample liquid on the upper side and a drainage tube body with a thinner diameter on the lower side. When in use, the sample is added to the holding cavity through a sample pipette, and then the sample can flow uniformly onto the ferroscope sheet through the drainage tube body. A cleaning bracket is installed on the top of the thistle tube support, and a cleaning agent bottle is installed on the cleaning bracket. When the sample liquid in the thistle tube flows out and the thistle tube needs to be cleaned, the cleaning agent in the cleaning agent bottle flows into the thistle tube to clean the thistle tube.

[0004] The existing iron spectrometer has a coverless structure with an opening on the tube, so that the sample is directly exposed to the external environment during detection, and dust is easily attached to its surface, causing the sample to be contaminated, affecting the accuracy of the test results. Secondly, when cleaning the tube, the toxic tetrachloroethylene solvent drips into the sample tank and easily evaporates into the air, polluting the external environment and causing harm to the human body.

[0015] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0016] The analytical iron spectrometer of the utility model is mainly aimed at the problem that the thistle tube of the existing iron spectrometer is an upper open structure as a whole, and the sample is directly exposed to the external environment, which is easy to adhere to dust and cause inaccurate sample detection results. By arranging a shielding cover above the upper opening of the thistle tube, it can play a certain shielding and protective role, preventing dust in the external environment from falling onto the sample in the thistle tube, preventing the sample from being contaminated, and thus ensuring the accuracy of the detection result.

[0017] Specifically, take the implementation method described below as an example. Figure 1-2 As shown, an embodiment of a ferrogram instrument includes a base, a bearing platform and a ferrogram 6 bracket are provided on the base, a ferrogram sheet 7 is obliquely installed on the bearing platform, a liquid discharge pipe 8 is provided at the lower end of the ferrogram sheet 7, and a waste liquid cup 9 is placed on the base below the outlet of the liquid discharge pipe 8. A cleaning bracket is provided on the top of the ferrogram 6 bracket, and a cleaning agent bottle 1 is placed on the cleaning bracket for containing cleaning agent. The ferrogram 6 is installed on one side of the ferrogram 6 bracket in rotation around an axis extending up and down, and a driving mechanism is provided on the other side, and the driving mechanism bypasses the ferrogram 6 through a driving belt 5 and can drive the ferrogram 6 to rotate. A shielding cover 4 is fixedly installed on the ferrogram 6 bracket at the upper position of the ferrogram 6, and the shielding cover 4 shields the upper opening of the ferrogram 6, thereby preventing dust in the external environment from falling into the ferrogram 6 and contaminating the sample. Since the ferrogram 6 in this embodiment can be driven to rotate by the driving mechanism, in order not to affect the rotation of the ferrogram 6, the shielding cover 4 is arranged close to the upper opening of the ferrogram 6 but has a gap between the shielding cover 4 and the upper opening of the ferrogram 6.

[0018] Since the shielding cover 4 is fixedly mounted on the bracket of the thistle tube 6 and is arranged close to the opening of the thistle tube 6, in order to facilitate the addition of samples to the thistle tube 6, a sample addition hole is arranged on the shielding cover 4 at a position directly opposite to the opening of the thistle tube 6. The sample addition hole matches the size of the sample addition pipette, and the sample addition pipette can be inserted into and add the sample liquid to the thistle tube 6. The sample addition hole is preferably arranged in the middle of the shielding cover 4, so that the sample can be directly added to the bottom center of the accommodating cavity of the thistle tube 6.

[0019] In order to facilitate the filling of cleaning agent into the thistle tube 6, a cleaning tube 3 perforation is also provided on the shielding cover 4. A cleaning agent outlet 2 is provided at the bottom of the cleaning agent bottle 1, and the cleaning tube 3 is installed on the cleaning agent outlet 2 and extends downward, and extends into the thistle tube 6 after passing through the cleaning tube 3 perforation. The cleaning tube 3 is made of polytetrafluoroethylene, and the inner diameter is consistent with the outer diameter of the cleaning agent outlet 2; the upper end is a flat cut, tightly sleeved on the cleaning agent outlet 2, and the lower end is an oblique cut. In order to save cleaning agent and better clean the thistle tube 6, the cleaning tube 3 perforation is set at a position of the shielding cover 4 corresponding to the inner wall of the thistle tube 6, and is slightly attached to the inner wall of the thistle tube 6, so that the cleaning agent can flow downward along the inner wall of the thistle tube 6, thereby cleaning the sample liquid adhering to the inside. Moreover, with such an arrangement, the bottle cap of the cleaning agent bottle 1 can achieve sealing of the cleaning agent bottle 1, and the cleaning agent does not come into contact with the external environment during the process of flowing downward from the cleaning agent bottle 1 to the thistle tube 6. The shielding cover 4 can also play a shielding role after the cleaning agent flows into the thistle tube 6, so that the toxic substances in the cleaning agent are not easily volatilized into the air and cause harm to the human body.

[0020] Of course, in some other embodiments, the sample addition holes on the shielding cover 4 and the perforations of the cleaning tube 3 can be arranged symmetrically with respect to the center of the thistle tube 6. Alternatively, the shielding cover 4 can be arranged slightly higher, and the interval formed between the shielding cover 4 and the opening on the thistle tube 6 constitutes the sample addition interval and the cleaning agent filling interval, and the sample liquid and the cleaning agent are added to the thistle tube 6 from the interval, and the cleaning agent outlet 2 at the bottom of the cleaning agent bottle 1 is connected to the soft cleaning tube 3, and the cleaning tube 3 is led to the cleaning agent filling interval. At this time, the shielding cover 4 is a complete cover body, and the sample addition holes and the perforations of the cleaning tube 3 are no longer set.

[0021] In this embodiment, the shielding cover 4 includes a main cover body and a fixing ear arranged on the edge of the main cover body, the fixing ear is arranged vertically with the main cover body, a fixing connection hole 10 is provided on the fixing ear, and the fixing ear is attached to the side of the bracket of the thistle tube 6 and fixedly connected by a connector installed in the fixing connection hole 10. The size of the main cover body is larger than the size of the upper opening of the thistle tube 6, so that it can better play a shielding role. Preferably, in one embodiment, the edge of the main cover body is also provided with a skirt extending downward, and the height of the lower side of the skirt is lower than the height of the upper opening of the thistle tube 6, so that the upper opening of the thistle tube 6 can be covered inside, achieving a better dustproof sealing effect.

[0022] There are many ways to fix the shielding cover 4 on the bracket of the thistle tube 6. In one embodiment, a connecting through hole is opened on the bracket of the thistle tube 6, and a screw hole is provided on the edge of the shielding cover 4 corresponding to the connecting through hole. The shielding cover 4 is fixedly installed on the bracket of the thistle tube 6 by a connecting screw that passes through the connecting through hole and is screwed into the screw hole.

[0023] When the analytical iron spectrometer of the utility model is used, a straw is used to move the diluted qualified sample through the sample addition hole of the shielding cover 4 to the tube 6. The sample in the tube 6 flows downward evenly, flows through the iron spectrum sheet 7 and is deposited under the action of the magnetic field, and the excess sample flows through the drainage pipe 8 to the waste liquid cup 9. After the sample in the tube 6 has flowed out, press the instrument "START / STOP" to start the timed rinsing, and the rinsing is generally 9 minutes. At this time, the driving belt 5 drives the tube 6 to rotate slowly, and the detergent in the detergent bottle 1 drips from the detergent outlet 2 through the cleaning tube 3 into the tube 6 rotating with the driving belt 5, cleans the residual liquid adhering to the inner wall of the tube 6 and flows through the iron spectrum sheet 7, rinses the excess sample on the iron spectrum sheet 7 together, and finally flows into the waste liquid cup 9.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
