Description

Technical Field

[0001] The utility model relates to the technical field related to magnetic separators, in particular to a pressure roller scraper for a magnetic separator. Background Art

[0002] In grinding, with the improvement of machining accuracy, high-speed grinding and strong grinding technologies are developing rapidly. In addition to selecting reasonable grinding parameters, the circulation quality of cutting fluid must also be improved. Cutting fluid often contains a large amount of magnetic impurities, so a purification device is required to remove these magnetic impurities. Magnetic separator is one of the purification devices used to purify cutting fluid. Existing magnetic separators usually include a shell, a magnetic roller and a pressure roller arranged on the shell, a motor arranged on the outside of the magnetic roller and driving the magnetic roller to rotate, and a scraper in contact with the magnetic roller. After the cutting fluid containing magnetic impurities enters the shell, as the magnetic roller continues to rotate, the magnetic impurities are adsorbed on the outer wall of the magnetic roller, and then the liquid entrained in the magnetic impurities is squeezed out by the pressure roller. Finally, the scraper separates the magnetic impurities from the magnetic roller, thereby achieving the purification of the cutting fluid.

[0003] The magnetic roller in a general magnetic separator needs to be used in conjunction with a magnetic roller scraper and a pressure roller. The dirty liquid in the metal chips adsorbed by the magnetic roller is squeezed out by the pressure roller, and the dehydrated metal chips are scraped off by the magnetic roller scraper and discharged into a collection device. However, as the magnetic roller rotates, the dirty liquid on the pressure roller is easily accumulated on the upper surface of the magnetic roller, causing the bottom of the squeezed metal chips to still be easily stained with dirty liquid after the magnetic roller moves, affecting the subsequent processing effect. For this reason, technical personnel in this field have proposed a pressure roller scraper for a magnetic separator to solve the problems raised in the above background. Utility Model Content

[0004] The utility model aims to provide a pressure roller scraper for a magnetic separator to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A pressure roller scraper for a magnetic separator comprises a box body, a magnetic roller is installed on one side of the inner cavity of the box body, a rubber pressure roller is installed on the top of the inner cavity of the box body, the bottom of the rubber pressure roller is in contact with the top of the magnetic roller, the rubber pressure roller is located on one side of the top of the magnetic roller, a new scraper is installed on the side of the rubber pressure roller away from the magnetic roller, the horizontal positions of the new scraper and the magnetic roller are staggered, a magnetic roller scraper is installed on the side of the magnetic roller away from the rubber pressure roller, the new scraper is used to scrape dirty liquid on the rubber pressure roller and discharge it into the box body, and the magnetic roller scraper is used to scrape metal chips on the magnetic roller.

[0007] As a further solution of the utility model: the bottom of the novel scraper is in an acute angle shape, and a plurality of drainage holes are arranged at equal intervals on the bottom of the novel scraper along its length direction.

[0008] As a further solution of the utility model: the upper part of the novel scraper is in a right-angle shape, and the upper part of the novel scraper is detachably mounted on the top of the box body by bolts.

[0009] As a further solution of the utility model: the bottom blade tip of the novel scraper abuts against one side of the lower part of the rubber pressure roller.

[0010] As a further solution of the utility model: the top blade tip of the magnetic roller scraper abuts against one side of the upper part of the rubber pressure roller.

[0011] As a further solution of the utility model: the contact position between the rubber pressure roller and the magnetic roller is located below the contact position between the novel scraper and the rubber pressure roller.

[0012] The utility model has the following advantages: the new scraper in the pressure roller scraper structure acts on the lower side of the rubber pressure roller, the positions of the new scraper and the magnetic roller are staggered, and the excess dirty liquid on the pressure roller can be scraped off and discharged into the box body. Compared with the conventional old scraper, the scraped dirty liquid can be prevented from being discharged onto the magnetic roller, thereby ensuring the dehydration effect of the pressure roller on the metal chips and ensuring the subsequent treatment effect of the metal chips.

[0018] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0019] Example 1: Please refer to Figures 2 to 4, a pressure roller scraper for a magnetic separator, comprising a box body 1, a magnetic roller 3 is installed on one side of the inner cavity of the box body 1, a rubber pressure roller 5 is installed on the top of the inner cavity of the box body 1, the bottom of the rubber pressure roller 5 is in contact with the top of the magnetic roller 3, the rubber pressure roller 5 is located on the top side of the magnetic roller 3, a new scraper 6-2 is installed on the side of the rubber pressure roller 5 away from the magnetic roller 3, the horizontal positions of the new scraper 6-2 and the magnetic roller 3 are staggered, a magnetic roller scraper 4 is installed on the side of the magnetic roller 3 away from the rubber pressure roller 5, the new scraper 6-2 is used to scrape the dirty liquid 2 on the rubber pressure roller 5 and discharge it into the box body 1, and the magnetic roller scraper 4 is used to scrape the metal chips on the magnetic roller 3.

[0020] See also Figures 2 to 4 The bottom of the new scraper 6-2 is acute-angled, and a plurality of drainage holes are arranged at equal intervals along the length direction of the bottom of the new scraper 6-2. The upper part of the new scraper 6-2 is right-angled, and the upper part of the new scraper 6-2 is detachably mounted on the top of the box body 1 by bolts. The setting height of the new scraper 6-2 can be adjusted according to the height of the box body 1.

[0021] Example 2: See Figure 2 On the basis of the first embodiment, the bottom blade tip of the new scraper 6-2 abuts against one side of the lower part of the rubber pressure roller 5, and the new scraper 6-2 acts on the lower part of the rubber pressure roller 5 to ensure that the dirty liquid 2 on the rubber pressure roller 5 can be quickly discharged.

[0022] See also Figure 2 The top blade tip of the magnetic roller scraper 4 abuts against one side of the upper portion of the rubber pressure roller 5 , and the magnetic roller scraper 4 can quickly discharge the metal chips to an external collection device.

[0023] See also Figure 2 The contact position between the rubber pressure roller 5 and the magnetic roller 3 is located below the contact position between the new scraper 6-2 and the rubber pressure roller 5, and the contact position between the rubber pressure roller 5 and the magnetic roller 3 is too close to the new scraper 6-2.

[0024] Working principle: Figure 1The figure shows the installation position of the old scraper 6-1 in the prior art. After the old scraper 6-1 scrapes the dirty liquid 2 on the rubber pressure roller 5, the dirty liquid 2 will flow to the magnetic roller 3, and then affect the bottom of the metal chips on the magnetic roller 3. The new scraper 6-2 in the present application is located on different sides of the rubber pressure roller 5 from the magnetic roller 3. The magnetic roller 3 and the rubber pressure roller 5 rotate relative to each other, and the metal chips adsorbed on the magnetic roller 3 are squeezed by the pressure roller. The dehydrated metal chips are scraped off by the magnetic roller scraper 4 and discharged. The dirty liquid 2 on the rubber pressure roller 5 is scraped off by the new scraper 6-2 and discharged into the box 1. The discharge direction of the drainage hole in the new scraper 6-2 is opposite to the feeding direction of the metal chips on the magnetic roller 3, thereby avoiding the dirty liquid 2 from affecting the metal chips.
