Description

TECHNICAL FIELD

[0001] The present application belongs to the field of filling equipment, in particular to a defoaming component and a filling valve. BACKGROUND

[0002] In the field of filling, the material with certain viscosity collides with the inner wall of the machine and each other during the conveying process, and air is mixed in, resulting in the formation of bubbles inside the material. The material containing a large number of bubbles will result in the actual filling weight in the filling container being lower than the set value during filling, affecting the filling accuracy, and the bubbles may float up in the filling container, and the floating bubbles are easy to overflow the filling container and adhere to the outer surface of the filling container or other parts, causing the accumulation of dirt or the breeding of bacteria, resulting in hygiene problems.

[0003] At present, in order to eliminate the bubbles in the material during the filling stage, a grid is usually arranged at the material output part of the filling valve to cut the bubbles in the material. However, because the material flow rate after being cut by the grid is fast, the bubbles are still generated by mutual collision during the filling process. SUMMARY

[0005] To solve the above technical problems, the present application adopts the following technical scheme: a defoaming component, comprising a mounting sleeve provided with a discharging channel and a flow interception seat arranged in the discharging channel, the flow interception seat comprising a hollow cylinder and a partition plate arranged inside the cylinder, the partition plate being perpendicular to the central axis of the cylinder to separate the inside of the cylinder into a feeding groove and a discharging groove with opposite opening directions, the side wall of the cylinder being provided with a first flow guide hole and a second flow guide hole, the first flow guide hole being spaced around the feeding groove and being in communication with the feeding groove, the second flow guide hole being spaced around the discharging groove and being in communication with the discharging groove, a flow guide cavity being formed between the cylinder and the mounting sleeve, and the first flow guide hole and the second flow guide hole being in communication through the flow guide cavity.

[0006] In the above defoaming component, the diameter of the first flow guide hole is larger than that of the second flow guide hole.

[0007] In the above defoaming component, the outer diameter of the middle part of the cylinder is smaller than the outer diameter of the two ends of the cylinder to form the flow guide cavity between the cylinder and the mounting sleeve; or, the inner side wall of the discharging channel is provided with annular first and second stop ribs, and the outer side wall of the two ends of the cylinder abuts against the inner side wall of the discharging channel through the first and second stop ribs to form the flow guide cavity.

[0008] In the defoaming component, the defoaming component further comprises a flow dividing plate arranged in the discharge channel, the flow dividing plate is located at the discharge end of the intercepting seat, and the flow dividing plate is provided with a plurality of flow dividing holes with a smaller diameter than the second flow guide hole.

[0009] In the defoaming component, the defoaming component further comprises a defoaming net arranged in the discharge channel, the defoaming net is located on the side of the flow dividing plate away from the intercepting seat, and the defoaming net has a smaller diameter than the flow dividing hole.

[0010] In the defoaming component, a plurality of defoaming nets are arranged, the plurality of defoaming nets are distributed along the axial direction of the discharge channel, and the plurality of defoaming nets have diameters gradually decreasing along the flow direction of the material.

[0011] In the defoaming component, the middle part of the upper surface of the partition plate is upwardly protruded to form a first protrusion.

[0012] In the defoaming component, the edge part of the upper surface of the partition plate is upwardly protruded to form a second protrusion, so that the part between the first protrusion and the second protrusion is concave downward.

[0013] The defoaming component has the following beneficial effects:

[0014] The defoaming component comprises a mounting sleeve provided with a discharge channel and an intercepting seat arranged in the discharge channel, the intercepting seat comprises a hollow cylinder and a partition plate arranged in the interior of the cylinder, the partition plate is perpendicular to the central axis of the cylinder to divide the interior of the cylinder into a feeding groove and a discharge groove with opposite opening directions, the side wall of the cylinder is provided with a first flow guide hole and a second flow guide hole, the first flow guide hole is distributed around the feeding groove at intervals and communicates with the feeding groove, the second flow guide hole is distributed around the discharge groove at intervals and communicates with the discharge groove, the cylinder and the mounting sleeve form a flow guide cavity, and the first flow guide hole and the second flow guide hole communicate through the flow guide cavity. The technical scheme has the following technical effects:

[0015] The application sets the intercepting seat in the discharge channel of the mounting sleeve, so that the material in the discharge channel flows through the intercepting seat first, flows into the feeding groove through the opening at the top of the feeding groove, then turns under the block of the partition plate, enters the flow guide cavity formed between the inner wall of the intercepting seat and the discharge channel through the first flow guide hole, then turns to enter the discharge groove through the second flow guide hole, and finally flows out through the opening at the bottom of the discharge groove. The partition plate is arranged to prevent the material in the feeding groove from flowing directly into the discharge groove, and the material needs to flow through the first flow guide hole, the flow guide cavity and the second flow guide hole in sequence to enter the discharge groove, so that the material needs to turn multiple times during the flow, greatly reducing the impact force of the material entering the discharge groove, avoiding a large number of bubbles in the material due to the too fast flow speed, and increasing the pressure around the bubbles in the material during the flow of the material, so that the bubbles in the material are crushed by the surrounding material. Meanwhile, the arrangement of multiple first flow guide holes and second flow guide holes can split and break the bubbles in the material, avoid the material containing a large number of bubbles from being filled into the filling container to cause the actual filling weight in the filling container to be lower than the set value, ensure the filling accuracy, and avoid a large number of bubbles from overflowing or adhering to the outer surface of the filling container to breed bacteria.

[0016] The diameter of the first flow guide hole is larger than that of the second flow guide hole, that is, the diameter of the flow guide hole through which the material containing bubbles flows gradually decreases when the material flows through the intercepting seat, and the diameter of the second flow guide hole is smaller than that of the first flow guide hole, so that the second flow guide hole can further split and break the bubbles in the material that the first flow guide hole fails to split and break, and the bubble breaking effect is better.

[0017] The defoaming component further comprises a flow dividing plate arranged in the discharge channel, the flow dividing plate is located at the discharge end of the intercepting seat, and the flow dividing plate is provided with multiple flow dividing holes with diameters smaller than that of the second flow guide hole. The material flowing out of the discharge opening of the intercepting seat passes through the flow dividing holes on the flow dividing plate before flowing out of the discharge channel, so that the material passing through the flow dividing plate is regulated, and the diameters of the flow dividing holes are smaller than that of the second flow guide hole, so that the flow dividing plate can split the bubbles with smaller diameters in the material flowing out of the intercepting seat.

[0018] The defoaming component further comprises a defoaming mesh arranged in the discharge channel, the defoaming mesh is located on the side of the flow dividing plate away from the intercepting seat, and the diameter of the defoaming mesh is smaller than that of the flow dividing hole. When the material flows in the discharge channel, it will pass through the intercepting seat, the flow dividing plate and the defoaming mesh in sequence, and the diameter of the defoaming mesh is smaller than that of the flow dividing hole, so that the defoaming mesh can further split the bubbles in the material flowing out of the flow dividing hole. Because a small amount of small bubbles cannot quickly float and gather to form foam during the filling process, the formation or overflow of foam in the filling container during the filling process can be avoided.

[0019] The defoaming nets are provided in plurality, the plurality of defoaming nets are distributed along the axial direction of the discharging channel, and the pore diameters of the plurality of defoaming nets gradually decrease along the flow direction of the material. The plurality of defoaming nets can segment the bubbles in the flowing material layer by layer, gradually reduce the volume of the bubbles, and the downstream defoaming net can segment the bubbles that are not segmented in time by the upstream defoaming net, to avoid the generation of foam in the filling container.

[0020] The middle part of the upper surface of the partition plate is upwardly protruded to form a first protrusion. The first protrusion can guide the material flowing longitudinally into the feeding groove, and guide the material to flow to the first flow guide hole in all directions, to avoid the material vertically impacting the horizontally arranged partition plate to generate a large amount of bubbles.

[0021] The edge part of the upper surface of the partition plate is upwardly protruded to form a second protrusion, so that the part between the first protrusion and the second protrusion is downwardly recessed, to further guide and buffer the material after being guided and turned by the first protrusion, guide the material to flow to the first flow guide hole, and make the material flow in the feeding groove more moderate, to avoid generating a large amount of bubbles.

[0022] The application also provides a filling valve, which comprises a valve body, the defoaming component is mounted on the valve body, and a mounting sleeve is mounted on the discharging end of the valve body, so that the opening of the feeding groove is communicated with the discharging port of the valve body. By mounting the defoaming component on the discharging end of the valve body, when the filling valve fills the container, the material will first pass through the defoaming component to cut the bubbles, and then be filled into the filling container, to avoid filling the material containing a large amount of bubbles into the filling container.

[0042] Embodiment one:

[0043] A defoaming component, such as Figures 1 to 3 As shown, the defoaming component comprises a mounting sleeve 200 and a cutoff seat 300. The mounting sleeve 200 is provided with a material outlet channel 210 longitudinally penetrating the mounting sleeve 200 for allowing material to pass therethrough. The cutoff seat 300 is arranged in the material outlet channel 210 and comprises a cylinder 310 and a partition plate 320. The cylinder 310 is hollow. The partition plate 320 is horizontally arranged in the cylinder 310 and is perpendicular to the central axis of the cylinder 310, so as to divide the internal space of the cylinder 310 into a material inlet groove 311 and a material outlet groove 313. The material inlet groove 311 is located above the partition plate 320 and is provided with an upward opening for being communicated with the material inlet end of the material outlet channel 210. The material outlet groove 313 is located below the partition plate 320 and is provided with a downward opening for being communicated with the material outlet end of the material outlet channel 210. A plurality of first flow guide holes 312 and a plurality of second flow guide holes 314 are further arranged on the side wall of the cylinder 310. The plurality of first flow guide holes 312 are arranged on the side wall of the material inlet groove 311 and are distributed around the material inlet groove 311 in a spaced manner and are communicated with the material inlet groove 311. The plurality of second flow guide holes 314 are arranged on the side wall of the material outlet groove 313 and are distributed around the material outlet groove 313 in a spaced manner and are communicated with the material outlet groove 313. The upper end and the lower end of the outer side wall of the cylinder 310 are in abutment with the inner wall of the material outlet channel 210. The middle part of the outer side wall of the cylinder 310 and the inner wall of the material outlet channel 210 form a flow guide cavity 220. The first flow guide holes 312 and the second flow guide holes 314 are respectively communicated with the flow guide cavity 220.

[0044] The present application sets the intercepting seat 300 in the discharging channel 210 of the mounting sleeve 200, so that the material in the discharging channel 210 flows into the feeding groove 311 through the opening at the top of the feeding groove 311 first, then turns under the block of the partition plate 320, enters the flow guide cavity 220 formed between the intercepting seat 300 and the inner wall of the discharging channel 210 through the first flow guide hole 312, then turns and enters the discharging groove 313 through the second flow guide hole 314, and finally flows out through the opening at the bottom of the discharging groove 313. The partition plate 320 is arranged so that the material in the feeding groove 311 cannot flow directly into the discharging groove 313, but needs to pass through the first flow guide hole 312, the flow guide cavity 220 and the second flow guide hole 314 in sequence to enter the discharging groove 313. The material needs to turn several times during the flow, which greatly reduces the impact force of the material entering the discharging groove 313, avoids a large number of bubbles generated inside the material due to too high flow speed, and also avoids foaming when the material is filled into the filling container. The reduction of the flow speed during the flow of the material increases the pressure around the bubbles in the material, so that the bubbles in the material are crushed by the surrounding material. At the same time, the arrangement of the plurality of first flow guide holes 312 and second flow guide holes 314 can split and break the bubbles in the material, avoid the actual filling weight in the filling container being lower than the set value due to the material containing a large number of bubbles being filled into the filling container, ensure the filling accuracy, and also avoid the foam formed by a large number of bubbles floating in the filling container overflowing or adhering to the outer surface of the filling container to breed bacteria.

[0045] Preferably, the first flow guide hole 312 has a larger diameter than the second flow guide hole 314, that is, the diameter of the flow guide hole through which the material containing bubbles flows gradually decreases when passing through the intercepting seat 300. The diameter of the second flow guide hole 314 is smaller than that of the first flow guide hole 312, so that the second flow guide hole 314 can further split and break the bubbles in the material that the first flow guide hole 312 fails to split and break, and the breaking effect is better.

[0046] In the embodiment, the outer diameter of the middle part of the cylinder body 310 is smaller than the outer diameter of the two ends of the cylinder body 310, that is, the outer diameter of the cylinder body 310 gradually decreases from the upper end to the lower end to the middle part, so that the outer side wall of the cylinder body 310 is recessed to the center position to form the flow guide cavity 220 between the inner wall of the discharge channel 210, and the outer side wall of the upper end and the lower end of the cylinder body 310 abuts against the inner wall of the discharge channel 210 to avoid the upper side and the lower side of the flow guide cavity 220 directly communicating with the discharge channel 210, which is simple and reliable in structure. In order to quickly install and position the intercepting seat 300, the inner wall of the cylinder body 310 is provided with an installation step 230, the bottom of the intercepting seat 300 abuts against the installation step 230, and an annular pressing plate 240 is further installed in the cylinder body 310, the annular pressing plate 240 abuts against the bottom of the intercepting seat 300 to press the intercepting seat 300 on the installation step 230, so as to limit the position of the intercepting seat 300 in the discharge channel 210.

[0047] As shown in Figure 1 The defoaming component further includes a flow distribution plate 400, which is horizontally arranged in the discharge channel 210 and perpendicular to the center axis of the discharge channel 210, and is located at the discharge end below the intercepting seat 300. A plurality of flow distribution holes 410 are arranged on the flow distribution plate 400. The material flowing out of the discharge port of the intercepting seat 300 will pass through the flow distribution holes 410 on the flow distribution plate 400 before flowing out of the discharge channel 210, so as to regulate the material passing through the flow distribution plate 400. The diameter of the flow distribution hole 410 is smaller than that of the second flow guide hole 314, so that the flow distribution plate 400 can preliminarily divide the small bubbles in the material flowing out of the intercepting seat 300.

[0048] The defoaming component in the embodiment also comprises a defoaming screen 500 arranged in the discharge channel 210 and parallel to the flow distribution plate 400, the defoaming screen 500 is located on the side of the flow distribution plate 400 away from the intercepting seat 300, i.e. below the flow distribution plate 400, when the material flows in the discharge channel 210, it will pass through the intercepting seat 300, the flow distribution plate 400 and the defoaming screen 500 in turn, the pore size of the defoaming screen 500 is smaller than that of the flow distribution hole 410, so that the defoaming screen 500 can further divide the bubbles in the material flowing out of the flow distribution hole 410, because a small amount of small bubbles cannot quickly float and gather to form foam during the filling process, so that the formation or overflow of foam in the filling container during the filling process can be avoided. The defoaming screen 500 can be provided with one or more than one, in order to enhance the division effect of the defoaming screen 500 on the bubbles, the defoaming screen 500 in the embodiment is provided with a plurality of defoaming screens 500, the plurality of defoaming screens 500 are equally spaced along the axial direction of the discharge channel 210, the pore sizes of the plurality of defoaming screens 500 are different, and the pore size of the defoaming screen 500 gradually decreases along the flow direction of the material, so that the plurality of defoaming screens 500 can divide the bubbles in the material flowing through layer by layer, gradually reducing the volume of the bubbles, and the downstream defoaming screen 500 can divide the bubbles that the upstream defoaming screen 500 fails to timely divide, avoiding the generation of foam in the filling container.

[0049] In the embodiment, the upper surface of the partition plate 320 is non-planar, the middle part of the upper surface of the partition plate 320 is upwardly convex to form a first convex part 321, the first convex part 321 is conical, and can guide the material flowing longitudinally into the feed groove 311, guiding the material to flow to the first flow guide hole 312 around, avoiding the material vertically impacting the horizontally arranged partition plate 320 to generate a large amount of bubbles. The edge part of the upper surface of the partition plate 320 is also upwardly convex to form a second convex part 322 in the form of a ring, the second convex part 322 forms an arc surface connected between the outer edge of the first convex part 321 and the inner side wall of the feed groove 311, so that the part of the upper surface of the partition plate 320 between the first convex part 321 and the second convex part 322 is concave, to further guide and buffer the material after being diverted by the first convex part 321, guiding the material to flow to the first flow guide hole 312, so that the flow of the material in the feed groove 311 is more moderate, reducing the flow rate of the material, and avoiding the generation of a large amount of bubbles.

[0050] Embodiment two:

[0051] The difference between the embodiment and embodiment one is that in the embodiment, the outer diameter of the cylinder is equal from top to bottom, in the form of a cylinder, and the inner side wall of the discharge channel is provided with a first blocking rib and a second blocking rib in the form of a ring, the inner circle of the first blocking rib abuts against the outer side wall of the upper end of the cylinder, and the second blocking rib abuts against the outer side wall of the lower end of the cylinder, to form a flow guide cavity between the outer side wall of the cylinder and the inner wall of the discharge channel, the flow guide cavity is located between the first blocking rib and the second blocking rib, reducing the production and processing difficulty of the intercepting seat and reducing the production cost.
