Detailed Description
The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
Example 1
As shown in figures 1-3, a fermentation tank with defoaming function comprises a tank body 1, wherein a plurality of upright posts 2 are fixedly connected to the bottom end of the tank body 1, the tank body 1 is supported by the upright posts 2, an air outlet 3 is arranged on the side wall of the tank body 1, a discharge outlet 4 is arranged at the bottom end of the tank body 1, a feeding channel 5 is fixedly connected to the top end of the tank body 1, the feeding channel 5 is opened and closed by a solenoid valve and is air-tight when in a closed state, a control panel 6 which is slidably connected with the inner side wall of the tank body 1 and the feeding channel 5 is arranged in the tank body 1, the cross section of the control panel 6 is of a circular structure, a plurality of vertical control rods 7 which are symmetrically arranged about the axis of the control panel 6 are fixedly connected to the bottom end of the control panel 6, a plurality of horizontally arranged fixing rods 8 are fixedly connected to the inner wall of, the bottom end of the upper sliding plate 11 is fixedly connected with a spring 12, and the bottom end of the spring 12 is fixedly connected with a lower sliding plate 13.
Further, the dead lever 8 is covered with filter screen 14 all around, when the foam passes through filter screen 14, the foam will be extruded by filter screen 14 mesh and broken, and then play the effect of defoaming, filter screen 14 bottom is towards sleeve 10 bottom opening part tilt up, the foam of jar internal portion 1 at first can climb along jar 1 inside wall gathering of the body, the foam with the contact of filter screen 14 bottom will be along filter screen 14 in entering into sleeve 10 from sleeve 10 bottom, and then at the inside progressive defoaming of sleeve 10. And the defoaming effect of the defoamer 9 can be improved.
Further, defoaming sleeve 10 inside wall fixedly connected with annular spacing 15, because the setting of spacing 15, after going down to a take the altitude, slide 11 will offset and can't continue to descend with spacing 15, thereby ensure that control panel 6 also can only descend to a take the altitude, and then play spacing effect, slide 13 during the rising with spacing 15 offset down simultaneously, slide 13 will can't continue to rise, under control panel 6's effect, slide 11 continues the upward movement, thereby can make the space increase between slide 11 and the slide 13, gas quality is unchangeable between slide 11 and the slide 13, thereby can make the atmospheric pressure between slide 11 and the slide 13 fall down, atmospheric pressure diminishes will make the inside and outside atmospheric pressure imbalance of foam, thereby make the foam broken.
Further, the distance from the limiting strip 15 to the top end of the defoaming sleeve 10 is greater than the distance between the upper sliding plate 11 and the lower sliding plate 13 in the natural state, so as to ensure that when the lower sliding plate 13 abuts against the limiting strip 15, and the upper sliding plate 11 continues to move upwards, a sealing system is still arranged among the upper sliding plate 11, the lower sliding plate 13 and the sleeve 10, so as to ensure that the air pressure between the upper sliding plate 11 and the lower sliding plate 13 can be reduced due to the increased volume, the distance from the limiting strip 15 to the opening at the bottom end of the sleeve 10 is less than the distance between the upper sliding plate 11 and the lower sliding plate 13 in the natural state, so as to ensure that when the upper sliding plate 11 abuts against the limiting strip 15, the lower sliding plate 13 can be separated from the bottom end of the sleeve 10, so as to ensure that foam can enter the sleeve 10 from the bottom of the lower sliding plate 13 and the bottom of the sleeve 10, and the distance from the control panel 6 to, and then when guaranteeing that lower slide 13 and spacing strip 15 offset, control panel 6 is still in gas outlet 3 below, and the internal air pressure of jar 1 can't be released, and air pressure still can promote control panel 6 upward movement, and then guarantees that control panel 6 can occasionally drive upper slide 11 and continue upward movement, and then guarantees that the space between upper slide 11 and lower slide 13 will be stretched, and here natural state all indicates that upper slide 13 and lower slide 13 do not all refer to the state with spacing strip 15 offset.
Furthermore, a connecting rod 16 is arranged between the two sleeves 10 which are close to each other along the inner wall direction of the tank body 1, two ends of the connecting rod 16 are fixedly connected with the two sleeves 10 respectively, and the connecting rod 16 can play a fixing role for the sleeves, so that the sleeves 10 are more stable.
Furthermore, the control panel 6 is connected with the inner wall of the tank body 1 in a sealing and sliding manner, and the upper sliding plate 11 and the lower sliding plate 13 are connected with the inner wall of the sleeve 10 in a sealing and sliding manner, so that no air leakage between the control panel 6 and the inner wall of the tank body 1 is ensured, and when the upper sliding plate 11 and the lower sliding plate 13 slide in the sleeve, a sealing system can be formed between the upper sliding plate 11 and the lower sliding plate 13, and the system is convenient to carry out pressure reduction and defoaming.
In the fermentation tank with the defoaming function, during the fermentation process, the air pressure in the tank body 1 will gradually increase, the air pressure will increase, the control plate 6 will be pushed to move upwards, the control plate will move upwards to drive the upper sliding plate 11 to slide upwards through the control rod 7, the upper sliding plate 11 will drive the lower sliding plate 13 to slide upwards through the spring 12, until the lower sliding plate 13 is completely connected with the inner wall of the sleeve 10 in a sealing and sliding manner, a sealing system is formed between the upper sliding plate 11 and the lower sliding plate 13 until the lower sliding plate 13 is abutted against the limiting strip 15, the upper slide plate 11 will continue to move upwards under the action of the control plate 6, the volume of the sealing system between the upper slide plate 11 and the lower slide plate 13 is stretched to be larger, therefore, the air pressure is reduced, and the foam in the sealing system with reduced air pressure is broken due to the change of air pressure, so that the purpose of defoaming is realized.
Example 2
As shown in fig. 4 to 5, the present embodiment is different from embodiment 1 in that:
the side wall of the sleeve 10 is provided with an opening 17 connected with the bottom end of the filter screen 14, bubbles will enter between the upper slide plate 11 and the lower slide plate 13 from the opening 17 along the filter screen 14, and further defoaming is realized in the upward movement process of the control panel 6, the bottom end of the sleeve 10 is fixedly connected with a defoaming plate 18, a plurality of groups of defoaming holes 19 are arranged in the defoaming plate 18, the defoaming holes 19 are composed of pore channels which become larger gradually from top to bottom and are communicated with each other, in the upward movement process of the control panel 6, the control panel 6 will drive the upper slide plate 11 to move upwards through the control rod 7, the upper slide plate 11 will drive the lower slide plate 13 to move upwards through the spring 12, the upward movement of the lower slide plate 13 will form a certain negative pressure with the bottom of the sleeve 10, and suck the foam at the bottom of the sleeve 10 into the sleeve 10 through the defoaming plate 18, when the, and further defoaming effect can be realized.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
