Please refer to fig. 1-6, this embodiment provides a novel protein defoaming pump, which includes a pump body 1, a first driving motor is fixedly installed at an upper end of the pump body 1, an impeller 12 is installed inside the pump body 1, an output shaft of the first driving motor extends into the pump body 1 and is connected with the impeller 12 in a key manner, in order to ensure that centrifugal force generated by rotation of the impeller 12 throws generated foam into the defoaming cavity 2, a liquid inlet pipe 10 is fixedly installed at a lower end of the pump body 1, a through hole 11 is opened on a front surface of the pump body 1, a defoaming cavity 2 is fixedly installed on the front surface of the pump body 1, the defoaming cavity 2 is communicated with the pump body 1 through the through hole 11, in order to eliminate the generated foam during liquid pumping of the water pump, foam-liquid separation is realized, so that liquid without foam is discharged from a liquid discharge pipe 20, a reciprocating screw rod 3 is connected to a bearing inside the defoaming cavity 2, a nut pair 30 is driven on the reciprocating screw rod 3, a scraper 4 is fixedly installed on an outer wall of the nut pair 30, an edge of the scraper 4 is movably matched with an inner wall of the defoaming cavity 2, in order to eliminate the foam inside of the defoaming cavity 2, a bottom of the defoaming cavity 2 is installed at a position of the left end, a middle of the defoaming pipe 21 is installed at a position of the surface of the defoaming cavity 2, and a middle of the defoaming pipe 20 is installed at the position.

The working process is as follows: when the impeller 12 moving in the pump body 1 rotates for transfusion, foam generated in the stirring process of the impeller 12 is thrown and extends into the defoaming cavity under the action of centrifugal force, the second driving motor is started, the output shaft of the second driving motor rotates to drive the reciprocating screw rod 3 to rotate, the reciprocating screw rod 3 rotates to enable the nut pair 30 which is mutually driven to move left and right along the outer wall of the reciprocating screw rod to drive the scraper 4 to move left and right along the inner wall of the defoaming cavity 2, the foam in the defoaming cavity 2 is scraped into the foam discharging pipe 21, the foam is discharged to the outside of the defoaming cavity 2 from the foam discharging pipe 21, the foam in the defoaming cavity 2 can be eliminated, the scraper 4 can scrape impurities in the foam in the defoaming cavity 2 into the foam discharging pipe 21, and the cleanness of liquid discharged from the liquid outlet pipe 20 is guaranteed.

From above, when scraper blade 4 moves to row's foam pipe 21 scraping department, if the lower tip of scraper blade 4 crosses row's foam pipe 21 upper mouth edge, probably to lead to arranging inside foam of foam pipe 21 to flow backward to defoaming chamber 2 inside, scraper blade 4 left side lies in upper and lower edge fixed and is equipped with blend stop 40, blend stop 40's length dimension equals with row's foam pipe 21 length dimension, when scraper blade 4 moves to row's foam pipe 21 department, blend stop 40 that equals with row's foam pipe 21 length dimension can play spacing effect, prevent that the lower tip of scraper blade 4 from crossing row's foam pipe 21 upper mouth edge, be favorable to avoiding arranging the inside foam of foam pipe 21 to flow backward to the phenomenon of defoaming chamber 2 inside.

And, when scraper blade 4 moved about along the inner wall in defoaming chamber 2, moved near nut pair 30, was difficult to guarantee that scraper blade 4 blocked when moving, and spout 22 has been seted up to the top and the bottom symmetry in defoaming chamber 2 inner wall, and blend stop 40 and spout 22 sliding connection, when scraper blade 4 moved about along defoaming chamber 2, spout 22 can guarantee the accuracy of the movement track of scraper blade 4, avoided appearing the circumstances of blocking.

As mentioned above, when the scraper 4 moves left and right along the inner wall of the defoaming chamber 2 to scrape the foam inside the defoaming chamber 2, the liquid and the foam inside the defoaming chamber 2 are squeezed, and in order to avoid the scraper 4 scraping the liquid away, the left surface of the scraper 4 is provided with a plurality of water leakage holes 41, and since the foam generally floats on the upper part of the liquid, the liquid can flow out from the water leakage holes 41 to the right side of the scraper 4 and flow out from the liquid outlet pipe 20.

In addition, considering that the foam in the pump body 1 of the protein defoaming pump is greatly effectively eliminated, the left surface of the scraper 4 is fixedly provided with a plurality of cones 42, and when the larger foam meets the cones 42, the cones 42 can puncture the larger foam, thereby playing a certain auxiliary role in eliminating the foam.

Secondly, because may contain impurity etc. in the foam, if flow out through drain pipe 20, can influence the cleanliness factor of the liquid that albumen defoaming pump output to in order to avoid scraper blade 4 again to scrape the foam of defoaming chamber 2 inside into the in-process of arranging foam pipe 21, there is a small amount of newly-produced foam to gush out, be located defoaming chamber 2 inside, the rear end department that is close to drain pipe 20 is equipped with filter screen 5, filter screen 5 is located the dead ahead of through-hole 11, filter screen 5 can play the effect of intercepting a small amount of foam.

In addition, the albumen defoaming pump when using for a long time, the condition that filter screen 5 blockked up may appear, is located the fixed brush 43 that is equipped with of 4 front end edge departments of scraper blade, and brush 43 and 5 clearance fit of filter screen, scraper blade 4 remove about 2 along the defoaming chamber at every turn, can drive brush 43 and brush the surface of filter screen 5, are favorable to avoiding filter screen 5 to block up.

When the novel protein defoaming pump is used specifically, when the impeller 12 moving in the pump body 1 rotates for transfusion, foam generated in the stirring process of the impeller 12 is thrown into the defoaming cavity under the action of centrifugal force, the output shaft of the second driving motor rotates to drive the reciprocating screw rod 3 to rotate, the scraper 4 can be driven to move left and right along the inner wall of the defoaming cavity 2, the foam in the defoaming cavity 2 is scraped into the foam discharging pipe 21 and discharged to the outside of the defoaming cavity 2 from the foam discharging pipe 21, so that the foam in the defoaming cavity 2 can be eliminated, the foam in the defoaming cavity 2 is scraped into the foam discharging pipe 21 by the scraper 4, the filter screen 5 can intercept a small amount of newly generated foam, and meanwhile, the scraper 4 moves left and right along the defoaming cavity 2 every time, the brush 43 can be driven to brush the surface of the filter screen 5, and the filter screen 5 is prevented from being blocked;

and the scraping plate 4 can scrape impurities contained in the foam in the defoaming chamber 2 into the foam discharging pipe 21, which is beneficial to ensuring the cleanliness of the liquid discharged from the liquid outlet pipe.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
