The specific structure of each part of the ball-receiving and-transmitting cylinder system according to the present invention will be described below.

(ball receiving station 1)

As shown in fig. 1, the ball collecting station 1 includes a ball collecting station main body 11, a ball collecting station ball cage 12, a blocking block 13, an end cover 14 and a quick release quick connector structure 15.

In the present embodiment, the station body 11 has a substantially cylindrical shape with both ends open in the axial direction a, and a hollow housing portion C1 is formed in a part of the inside of the station body 11, and the housing portion C1 houses the ball cage 12.

In the present embodiment, the ball station main body 11 is provided with three short connection pipes.

The ball receiving station body 11 is provided at one axial end with a first connecting stub 111 extending in the axial direction a, the first connecting stub 111 forming a first passage P1 extending in the axial direction a, and a free end of the first connecting stub 111 being adapted to be connected to the material pipeline by a quick release quick coupler structure 15 such that the first passage P1 communicates with the material passage. In the present embodiment, the first connection stub 111 is formed integrally with the ball station body 11.

The outer peripheral wall of the station body 11 is further provided with a second short connection pipe 112 and a third short connection pipe 113 projecting toward the radial outside in the radial direction R, the second short connection pipe 112 and the third short connection pipe 113 forming a second passage P2 and a third passage P3 extending in the radial direction R, respectively. The free end of the second connection stub 112 and the free end of the third connection stub 113 are also connected with the material pipeline and the propelling medium source (not shown) respectively by the quick release quick joint structure 15, so that the second passage P2 communicates with the material passage and the propelling medium of the propelling medium source can be conveyed to the receiving part C1 via the third passage P3.

The first passage P1, the second passage P2, and the third passage P3 formed by the three connecting

stub

111, 112, 113 are all communicated with the housing portion C1 inside the station body 11.

In the present embodiment, the ball collection station cage 12 has a substantially cylindrical shape with both ends open in the axial direction a, and the interior of the ball collection station cage 12 defines an internal passage D1. The ball cage 12 is fixed to the ball station body 11 and is housed in the housing portion C1 of the ball station body 11.

Specifically, the ball cage 12 includes a first axial portion 121, a plurality of link portions 122, and a second axial portion 123 along the axial direction a, and the first axial portion 121 and the second axial portion 123 are connected together by the plurality of link portions 122. The first axial portion 121 and the second axial portion 123 each extend continuously over the entire circumference along the circumferential direction of the ball receiving station cage 12, the first axial portion 121 and the second axial portion 123 each have a predetermined length in the axial direction a and the length of the first axial portion 121 in the axial direction a is greater than the length of the second axial portion 123 in the axial direction a. The inner diameter of the first axial portion 121 (preferably, the entire ball receiving station cage 12) is slightly smaller than the outer diameter of a skirt 32, described below, of the ball 3, so that the ball 3 and the first axial portion 121 can be interference-fitted with each other. Each link portion 122 has a linear shape extending along the axial direction a and has the same length in the axial direction a, and the plurality of link portions 122 are arranged at equal intervals in the circumferential direction of the ball cage 12.

When the ball collection station cage 12 is attached to the ball collection station body 11, the first axial portion 121 is closer to the first passage P1 than the second axial portion 123, an end surface of one axial end of the first axial portion 121 abuts against an inner wall of the ball collection station body 11, and a seal structure such as a seal ring is provided between the end surface and the inner wall. Specifically, the ball receiving station main body 11 has an inner peripheral surface formed with a mounting step surface against which an end surface of one axial end of the first axial portion 121 (ball receiving station cage 12) abuts in the axial direction a, and a seal ring as a seal structure is provided between the end surface and the mounting step surface. The other axial end of the ball receiving station cage 12 abuts the end cap 14 in the axial direction a. When the end cover 14 is attached to the ball collection station main body 11, a certain pressure is applied to the ball collection station cage 12 by the end cover 14, so that the end face of one axial end of the first axial portion 121 (the ball collection station cage 12) is brought into close contact with the attachment step face.

The ball collection station cage 12 is mounted to the ball collection station body 11 in a manner such that its axial direction coincides with the axial direction a of the ball collection station body 11, as described above, such that the inner passage D1 of the ball collection station cage 12 is aligned with the first passage P1, such that the scavenged balls 3 from the first passage P1 can enter the inner passage D1 and return from the inner passage D1 to the first passage P1. Through setting up and receiving ball station ball cage 12, can conveniently install the inside of receiving ball station 1 with the line ball 3, also conveniently take out line ball 3.

In the present embodiment, the blocking piece 13 is used for positioning the position of the ball sweeper ball 3 moving to the ball collecting station 1, and specifically, the blocking piece 13 is used for positioning the position of the ball sweeper ball 3 in the axial direction a in the internal channel D1 of the ball collecting station cage 12.

The blocking piece 13 is arranged in the inner channel D1 of the ball cage 12 of the ball collecting station. Specifically, in the axial direction a, the blocking piece 13 is located at a portion of the internal passage D1 of the ball collection station cage 12 corresponding to the plurality of link portions 122, so that a portion of the sweep ball 3 including at least the skirt 3 is positioned by the blocking piece 13 at a portion of the internal passage D1 corresponding to the first axial portion 121. In the present embodiment, the entire block 13 is located at the position where the plurality of link portions 122 are located in the axial direction a and the length of the block 13 is smaller than the length of the plurality of link portions 122.

Thus, after the blocking piece 13 stops the ball sweeper ball 3 at the inner passage D1 of the ball collecting station ball cage 12, the material can flow into the second passage P2 through the gap between the connecting rod parts 122 and thus into the material passage, while the propelling medium from the first passage P1 cannot enter the material passage. In the case of discharging the material remaining in the material line through the second passage P2 by means of the ball sweeper ball 3, no splashing of the propelling medium into the second passage P2 occurs. In the present embodiment, the block 13 is fixed to the end cap 14 by a long bolt.

In addition, one axial end of the block 13 is provided with a concave part matched with the shape and the size of the other axial end of the ball 3, so that the concave part can position and absorb shock for the ball 3 when the ball 3 moves to the ball cage 12 of the ball collecting station, thereby preventing the ball 3 from skewing and playing a role of buffering.

In the present embodiment, the end cap 14 abuts against the end surface of the other end in the axial direction of the ball drop station body 11 to close the opening of the other end in the axial direction of the ball drop station body 11.

The cap 14 includes a cover 141 and a handle 142 disposed on the cover 141. A seal ring is provided between the end surface of the cover 141 and the end surface of the other axial end of the ball collection station main body 11, and grooves corresponding to the seal ring are provided on both the end surface of the cover 141 and the end surface of the other axial end of the ball collection station main body 11. The outer peripheral edge of the cover body 141 and the peripheral edge of the axially other end of the ball receiving station body 11 are aligned with each other and fastened together by a clip. Thus, the end cover 14 covers the opening at the other axial end of the ball collection station body 11 in a manner detachable from the ball collection station body 11.

(quick release quick coupler structure 15)

The quick-release quick-assembly joint structure 15 for each pipeline of the ball receiving station 1 can greatly facilitate the connection between the ball receiving station 1 and the material pipeline and the medium pipeline, and is convenient to operate. The detailed structure of the quick release quick coupler structure 15 will be described in detail below.

In this embodiment, the quick release quick joint structure 15 is configured to include a first peripheral portion 151, a second peripheral portion 152, and a fastening ring 153. The quick-release quick-joint structure 15 of the first connecting short pipe 111 in fig. 1 is taken as an example to explain its specific structure in detail.

The first peripheral portion 151 is a flange that protrudes from the peripheral edge of the free end of the first short connection pipe 111 toward the radially outer side of the first short connection pipe 111, and the flange extends continuously over the entire circumference along the circumferential direction of the first short connection pipe 111.

The second peripheral portion 152 is a flange that protrudes from the periphery of the end of the material line for connection with the first connection stub 111 toward the radially outer side of the material line, and that extends continuously over the entire circumference in the circumferential direction of the material line. The end surface of the secondary peripheral portion 152 and the end surface of the primary peripheral portion 151 have shapes that match each other.

peripheral portions

151 and 152, so that the fastening ring 153 can be appropriately positioned when fitted over the primary and secondary

peripheral portions

151 and 152.

As shown in fig. 4, the fastening ring 153 has an overall ring shape and includes a first half ring portion 1531, a second half ring portion 1532, and a fastening member 1533. The first and second

half ring parts

1531 and 1532 each have an arc shape and correspond to a central angle of substantially 180 degrees with each other, and the first and second

half ring parts

1531 and 1532 have substantially the same shape and size as each other, respectively. One end of the first half ring portion 1531 is pivotally connected to one end of the second half ring portion 1532 by a pivot, and the other end of the first half ring portion 1531 is connected to the other end of the second half ring portion 1532 by a fastener 1533 such as a screw. The other end of the first half ring part 1531 and the other end of the second half ring part 1532 can be moved toward or away from each other by screwing the fastener 1533, which can enlarge or reduce the size of the entire fastening ring 153 composed of the first half ring part 1531 and the second half ring part 1532.

In addition, various sealing structures, such as sealing rings 154, may also be provided between the primary and secondary

peripheral portions

151, 152 to effect a seal between the first connection stub 111 and the material line. Both the primary and secondary

peripheral portions

151 and 152 are formed with corresponding structures to mount the sealing structure, for example, grooves corresponding to the sealing structure are formed at the primary and secondary

peripheral portions

151 and 152.

Further, in order to enable the primary and secondary

peripheral portions

151 and 152 to be accurately positioned with respect to each other, the primary and secondary

peripheral portions

151 and 152 form corresponding step structures.

(service station 2)

As shown in fig. 2, the service station 2 includes a service station body 21, a service station cage 22, a pushing structure 23, a joint 24, and a quick release quick joint structure 25.

In the present embodiment, the service station main body 21 has a substantially cylindrical shape with both ends open in the axial direction a, and a hollow storage portion C2 is formed in a part of the interior of the service station main body 21, and the storage portion C2 is used to store the service station cage 22.

In the present embodiment, the service station main body 21 is provided with three junction pipes.

The other axial end of the service station main body 21 is formed with a fourth short connecting pipe 211 extending along the axial direction a, the fourth short connecting pipe 211 forms a fourth passage P4 extending along the axial direction a, and the free end of the fourth short connecting pipe 211 is used for connecting with the material pipeline through the quick release quick connector structure 25, so that the fourth passage P4 is communicated with the material passage. In the present embodiment, the fourth connecting stub 211 is formed integrally with the service station main body 21.

The outer peripheral wall of the service station body 21 is further provided with a fifth connecting short pipe 212 and a sixth connecting short pipe 213 projecting toward the radial outside in the radial direction R, the fifth connecting short pipe 212 and the sixth connecting short pipe 213 forming a fifth passage P5 and a sixth passage P6 extending in the radial direction R, respectively. The free end of the fifth connecting stub 212 and the free end of the sixth connecting stub 213 also have quick release quick coupler structures 25, and the fifth passage P5 and the sixth passage P6 are used for the entrance and exit of the propelling medium, respectively. The fourth passage P4, the fifth passage P5, and the sixth passage P6 formed by the three connecting stub pipes 211, 212, 213 communicate with the housing portion C2 inside the service station main body 21.

In this embodiment, the service station ball cage 22 is generally cylindrical in shape with both ends open in the axial direction a, and the interior of the service station ball cage 22 defines an interior passage D2. The service station cage 22 is fixed to the service station body 21 and is housed in the housing portion C2 of the service station body 21.

Specifically, the service station cage 22 includes a first axial portion 221, a plurality of link portions 222, and a second axial portion 223 in the axial direction a, and the first axial portion 221 and the second axial portion 223 are connected together by the plurality of link portions 222. The first axial portion 221 and the second axial portion 223 each extend continuously over the entire circumference along the circumferential direction of the ball serving station cage 22, the first axial portion 221 and the second axial portion 223 each have a predetermined length in the axial direction a, and the length of the first axial portion 221 in the axial direction a is substantially equal to the length of the second axial portion 223 in the axial direction a. Each of the link portions 222 has a linear shape extending along the axial direction a and has the same length in the axial direction a, and the plurality of link portions 222 are arranged at equal intervals in the circumferential direction of the service station ball cage 22. The inner diameter of the whole service station ball cage 22 is slightly smaller than the outer diameter of the apron 32 of the sweep ball 3, so that the sweep ball 3 and the whole service station ball cage 22 can be in interference fit with each other.

When the service station cage 22 is attached to the service station body 21, the first axial portion 221 is closer to the fourth path P4 than the second axial portion 223, and the end surface of the other axial end of the first axial portion 221 abuts against the inner wall of the service station body 21. Specifically, the inner peripheral surface of the service station main body 21 is formed with a mounting step surface against which an end surface of the other axial end of the first axial portion 221 (service station cage 22) abuts. One axial end of the serving station cage 22 abuts against the joint 24. When the joint 24 is mounted on the service station body 21, a certain pressure is applied to the service station cage 22 by the joint 24 so that the end surface of the other end in the axial direction of the first axial portion 221 (service station cage 22) is brought into close contact with the mounting step surface. Due to the adoption of the design of the ball cage, the installation and the disassembly of the line sweeping ball 3 in the ball collecting station 2 can be facilitated.

The service station ball cage 22 is mounted to the service station body 21 in such a manner that the axial direction thereof coincides with the axial direction a of the service station body 21 in the manner as described above, so that the inner passage D2 of the service station ball cage 22 is aligned with the fourth passage P4, so that the scavenging balls 3 of the inner passage D2 can smoothly enter the fourth passage P4 and return from the fourth passage P4 to the inner passage D2.

In the present embodiment, the joint 24 is attached to the end surface of one axial end of the service station body 21 for closing the opening of one axial end of the service station body 21, and the attachment manner of the joint 24 is similar to that of the end cap 14 of the ball collection station 1. A central through hole for the push rod 233 of the push structure 23 to pass through is provided at the center of the joint 24.

In the present embodiment, the pushing structure 23 is used to push the ball sweeper ball 3 into the fourth passageway P4 so that the ball sweeper ball 3 can move in the material passageway towards the ball collecting station 1 via the pushing medium.

Specifically, the pushing structure 23 includes a cylinder 231, a slider 232, a push rod 233, a cushion block 234, and a protection block 235.

A cylindrical cylinder 231 is fixedly attached to the joint 24 so that the axial direction thereof coincides with the axial direction a of the service station main body 21, and a chamber in which the slider 232 slides is formed inside the cylinder 231. One axial end of the cylinder 231 is provided with a through hole for receiving/discharging a driving medium, the through hole communicating with the chamber of the cylinder 231; the peripheral wall of the cylinder 231 near the joint 24 is provided with a through hole for receiving/discharging the driving medium, which also communicates with the chamber of the cylinder 231. In the case where the slider 232 is required to slide in the cylinder 231, the driving medium is input from one of the two through holes, respectively, to achieve the reciprocating movement of the slider 232 in the chamber of the cylinder 231.

The slider 232 is housed in the chamber of the cylinder 231 so as to be capable of reciprocating along the chamber of the cylinder 231, and the slider 232 and the inner surface of the cylinder 231 are sealed by two seal rings, so that portions in the chamber of the cylinder 231, which communicate with the different through holes, are separated from each other.

The push rod 233 extends in the axial direction a, one axial end of the push rod 233 is fixed to the slider 232, and the push rod 233 passes through the central through hole of the joint 24, the other axial end of the push rod 233 extends into the inner passage D2 of the service station ball cage 22, and the other axial end of the push rod 233 is fixed to the protective block 235.

A spacer 234 is fixed to the cylinder 231 so as to abut against the joint 24 and is housed inside the cylinder 231, the spacer 234 is used to position the slider 232 in the chamber of the cylinder 231, and the spacer 234 also has a central through hole through which the push rod 233 passes.

As described above, the protection block 235 is fixed to the other axial end of the push rod 233 so that the protection block 235 can move with the movement of the slider 232 and the push rod 233. The protective blocks 235 are received within the interior channel D2 of the tee station cage 22. After the protective block 235 moves towards the other axial side along with the push rod 233, the protective block 235 can push the ball 3 in the ball cage 22 of the ball serving station into the fourth passage P4.

In the present embodiment, since the ball 3 is interference-fitted to the service station ball cage 22 and the ball receiving and delivery cylinder system is not operated, the ball 3 is positioned on one axial end side with respect to the sixth passage P6, and therefore, even if the pushing medium is introduced from the sixth passage P6, it is difficult to push the ball 3 into the fourth passage P4 positioned on the other axial end side with respect to the sixth passage P6. For this reason, the pushing mechanism 23 can push the ball 3 out of the ball cage 22 of the ball service station and into the fourth passage P4 by means of the push rod 233 and the protection block 235, and since the ball 3 is not in interference fit with the fourth passage P4, the pushing medium from the sixth passage P6 can easily push the ball 3 into the material passage from the fourth passage P4 and then move towards the ball receiving station 1.

In addition, in the present embodiment, the other end in the axial direction of the protection block 235 is provided with a recess matching both the shape and the size of the one end in the axial direction of the ball 3, so that the protection block 235 can play a role of positioning and buffering the ball 3. Specifically, the concave portion prevents the ball 3 from skewing in the service station cage 22 during the process of pushing the ball 3 to the fourth passage P4 through the protection block 235; when the ball 3 returns to the ball cage 22 of the ball-serving station from the material channel through the fourth channel P4, the concave part can play a role of shock absorption and buffer for the ball 3.

Further, in order to ensure that the ball 3 is pushed from the ball serving station cage 22 into the fourth passage P4, the pushrod 233 has a predetermined length and the distance between the slider 232 and the spacer 234 in the axial direction a is a predetermined value, which ensures that the pushrod 233 just pushes the ball 3 from the ball collecting station cage 22 into the fourth passage P4 through the protective block 235 when moving the predetermined distance. Further, to ensure that the protective block 235 is free to move with the pushrod 233 within the ball collection station cage 22, the protective block 235 and the ball collection station cage 22 are preferably in a clearance fit.

In the present embodiment, the quick release quick joint structure 25 is used for each pipeline of the ball serving station 2, and the quick release quick joint structure 25 has the same structure as the quick release quick joint structure 15 of the ball collecting station 1, and therefore, the details thereof will not be described here.

In the present embodiment, as shown in fig. 3, the ball 3 includes a ball body 31 and a plurality of skirts 32 provided on the ball body 31.

In the present embodiment, the ball main body 31 has a cylindrical shape, and both axial ends of the ball main body 31 have tapered shapes that are tapered toward both axial ends. Thus, the end portions of the blocking piece 13 of the ball collection station 1 and the protection piece 235 of the ball serving station 2 for abutting against both axial ends of the ball sweeping ball 3 are preferably formed with recesses matching the tapered shape described above to facilitate the positioning and pushing action of the ball sweeping ball 3.

In the present embodiment, the ball main body 31 is formed with two sets of the skirts 32, and each set of the skirts 32 has two skirts 32. Each apron 32 protrudes from the outer peripheral surface of the non-tapered portion of the ball sweeping body 31 toward the outside in the radial direction by a predetermined height such that the outer diameter of each apron 32 is slightly larger than the inner diameter of the service station ball cage 22, the inner diameter of the material passage, and the inner diameter of the ball collecting station ball cage 12, so that the ball sweeping ball 3 is in interference fit with each of the service station ball cage 22, the material passage, and the ball collecting station ball cage 12. In the present embodiment, the intervals between two skirts 32 in each set of skirts 32 are equal to each other.

Further, the ball 3 is preferably made of polyurethane or the like, and a magnet for detecting the position of the ball 3 may be further provided in the ball body 31.

The specific structure of the ball receiving and dispatching barrel system according to the present invention is explained in detail above, and the operation of the ball receiving and dispatching barrel system having the above structure is briefly explained as follows:

the first connecting short pipe 111 of the ball receiving station 1 and the fourth connecting short pipe 211 of the ball serving station 2 are respectively connected with a material pipeline, the line sweeping ball 3 is positioned in the ball serving station ball cage 22 of the ball serving station 2, and the ball receiving station 1 and the ball serving station 2 are not communicated with the material pipeline through a ball passing valve (not shown);

after the materials are conveyed through the material pipeline, a material valve (not shown) for controlling the material conveying is closed, a ball passing valve is opened to enable the ball serving station 2 and the ball collecting station 1 to be communicated with the material pipeline, the sweeping ball 3 is pushed to a preset position of a fourth channel P4 from an internal channel D2 of a ball cage 22 of the ball serving station through a pushing structure 23, a sixth channel P6 is closed, a fifth channel P5 is opened, and compressed gas is input through the fifth channel P5 to push the sweeping ball 3 to enter the material pipeline;

the ball 3 enters the first channel P1 through a material pipeline and finally reaches the inner channel D1 of the ball cage 12 of the ball collecting station 1, the ball 3 is positioned at a preset position of the inner channel D1 of the ball cage 12 of the ball collecting station through the blocking block 13, at the moment, the third channel P3 is closed, and the material swept out by the ball 3 is conveyed out through the second channel P2; and

closing the second channel P2 and the fifth channel P5, opening the third channel P3 and the sixth channel P6, inputting compressed gas through the third channel P3 to push the scavenging ball 3 into a material pipeline, returning the scavenging ball 3 to the fourth channel P4 of the ball service station 2 through the material pipeline and finally to an inner channel D2 of a ball service station ball cage 22 of the ball service station 2, positioning the scavenging ball 3 in the inner channel D2 of the ball service station ball cage 22 through a protective block 235, and closing the ball valve.

By adopting the working mode, the purpose of preventing splashing can be achieved. In addition, due to the arrangement of the stop block of the ball cage of the ball receiving station, compared with the ball receiving station of the ball receiving and dispatching barrel system in the prior art, the ball receiving station has the advantages that a pushing structure of the ball receiving station is omitted, and therefore cost is saved.
