Specifically, when the heat exchange tube needs to be cleaned, the rubber ball 100 is placed into the second ball storage chamber, the inner cylinder is switched to a ball receiving and serving state, namely the second connection hole 342 is communicated with the first connector 101 and the first connection hole 341 is communicated with the second connector 201, part of water flow is guided into the second ball storage chamber from the water inlet tube 1, the rubber ball 100 in the second ball storage chamber is stirred by the water flow and enters the water inlet tube 1, the water flow pushes the rubber ball 100 to wash the inner wall of the heat exchange tube, the rubber ball 100 flowing from the heat exchange tube to the water outlet tube 2 is recovered to the first ball storage chamber, when all the rubber balls 100 in the second ball storage chamber enter the water inlet tube 1 and all the rubber balls 100 are recovered to the first ball storage chamber, the inner cylinder is switched to a blocking state when the inner cylinder rotates 90 degrees relative to the outer cylinder, the inner cylinder is switched to another ball receiving and serving state when the inner cylinder rotates 180 degrees relative to the outer cylinder, the first connection hole 341 is connected with the first connector 101, the second connection hole 342 is connected with the second connector 201, water flows into the first ball storage chamber from the water inlet pipe 1, the rubber balls 100 in the first ball storage chamber are stirred by the water flows and enter the water inlet pipe 1, and the inner barrel part is rotated repeatedly in sequence, so that the heat exchange pipe can be cleaned continuously; when the heat exchange tube does not need to be cleaned or the rubber ball 100 needs to be replaced, the inner barrel part is switched to a blocking state, the first connecting hole 341 and the second connecting hole 342 face the inner wall of the outer barrel part, and the sealing lining 31 is tightly arranged between the outer wall of the inner barrel part and the inner wall of the outer barrel part, so that water flow in the water inlet tube 1 or the water outlet tube 2 cannot flow into the first ball storage chamber and the second ball storage chamber of the inner barrel part, an operator can take out the old rubber ball 100 contained in the second ball storage chamber, or put the new rubber ball 100 into the second ball storage chamber.

As shown in fig. 11, in particular, the sealing liner 31 includes two sealing rings 311 and at least four sealing strips 312 disposed at intervals, the two sealing rings 311 are disposed coaxially, each sealing strip 312 is connected between the two sealing rings 311, and the first connection hole 341 and the second connection hole 342 are disposed between the two sealing rings 311.

When the inner cylinder is switched to the blocking state, the water flow passing through the first connector 101 and the water flow passing through the second connector 201 are blocked by the sealing ring 311 and cannot continue to pass through the first connection hole 341 or the second connection hole 342, so that an operator can take out the old rubber balls 100 contained in the second ball storage chamber or throw new rubber balls 100 into the second ball storage chamber.

When the inner barrel is switched to the ball receiving and serving state, the water flow passing through the first connector 101 and the water flow passing through the second connector 201 directly pass through the direct gap of the two sealing strips 312 and continue to pass through the first connection hole 341 or the second connection hole 342.

When water backflow occurs in the ball storage chamber, the rubber ball 100 in the water outlet pipe 2 cannot pass through the second interface 201 and return to the ball storage chamber assembly 3, and the water backflow specifically refers to that part of water flow enters a gap between the inner cylinder member and the outer cylinder member from the first interface 101 and then flows into the water outlet pipe 2 from the second interface 201.

In this embodiment, no matter what state the inner cylinder is switched to or the rotation angle of the inner cylinder relative to the outer cylinder, the four sealing strips 312 uniformly spaced can prevent water from flowing from the water inlet pipe 1 to the second port 201 of the water outlet pipe 2 through the gap between the outer cylinder and the inner cylinder after passing through the first port 101, so as to prevent water from flowing back.

As shown in fig. 8, the outer barrel member includes two semi-annular clamps 33, one of the semi-annular clamps 33 is installed on the water inlet pipe 1, the other semi-annular clamp 33 is installed on the water outlet pipe 2, the inner walls of the two semi-annular clamps 33 are both provided with a semi-annular groove and an axial groove, the two semi-annular grooves are communicated to form an annular groove, the sealing ring 311 tightly abuts against the inner wall of the annular groove, and the sealing strip 312 tightly abuts against between the outer wall of the inner barrel member and the axial groove along the axial direction.

The half ring grooves can limit the axial movement of the sealing rings 311, and prevent the two sealing rings 311 from moving out of the inner barrel part and forming a section of the first connecting hole 341 and the second connector 201.

The axial groove can avoid sealing strip 312 to rotate along with the inner tube, avoids operating personnel to think that the inner tube has switched to the shutoff state by mistake and rivers still can pass first hole 341 or second hole 342 in fact, when rivers still can pass first hole 341 and second hole 342, then operating personnel can't take out old rubber ball 100 or put into new rubber ball 100, and can't judge the rotation state of inner tube.

In this embodiment, the two semi-annular bands 33 are both provided with water through holes, the inner cylinder member includes a first inner cylinder 34, the first connection hole 341 and the second connection hole 342 are both provided in the first inner cylinder 34, and one end of the first inner cylinder 34 provided with the first connection hole 341 and the second connection hole 342 extends into between the two semi-annular bands 33. When the inner cylinder is switched to a ball receiving and serving state, the first connection hole 341 and the second connection hole 342 can be respectively communicated with the water through holes of the two semi-annular clamps 33, and the semi-annular clamps 33 can limit the inner cylinder between the water inlet pipe 1 and the water outlet pipe 2.

The first inner cylinder 34 and the second inner cylinder 35 are independently arranged, so that the processing difficulty of the first inner cylinder 34 and the second inner cylinder 35 can be reduced.

Alternatively, the bottom of the first inner cylinder 34, the bottom of the second inner cylinder 35, and the bottom of the outer cylinder 36 can be removed to facilitate taking out the old rubber balls 100 from the second ball storage chamber and putting in new rubber balls 100.

The existing end cover type cleaning device is generally an asynchronous scheme for receiving and serving balls, namely, the balls need to be switched to a ball receiving state after being completely served, the switching needs time, a ball receiving channel is not opened at the moment, the rubber balls can be stayed on a ball receiving net, the process can last about one minute, the rubber balls are accumulated on the ball receiving net to cause water resistance increase, and the rubber balls are abraded in an accelerating manner.

The cleaning device of the embodiment divides the inner cavity of the ball storage chamber assembly into two parts, and the first ball storage chamber and the second ball storage chamber can synchronously send and receive balls respectively, so that the increase of water resistance caused by the accumulation of the rubber balls 100 at the first filter screen 4 is avoided.

In the embodiment, only one action (the inner cylinder member rotates once) is needed to simultaneously switch to the ball serving state and the ball receiving state, and the ball serving state is not needed to be switched first, and the ball receiving state is not needed to be switched after the ball serving is finished, so that the operating efficiency of the rubber ball 100 is greatly improved, and the cleaning requirement is met.

As shown in fig. 5, the cleaning device further includes a first filter screen 4 and a separating component 5, the first filter screen 4 is disposed inside the water outlet pipe 2, the first filter screen 4 separates the second connector 201 into a ball receiving channel 203 and a water return channel 202, the first filter screen 4 is used for guiding the rubber ball 100 to enter the ball receiving channel 203 from the inside of the water outlet pipe 2, the separating component 5 is disposed inside the water inlet pipe 1, the separating component 5 separates the first connector 101 into a water taking channel 102 and a ball serving channel 103, and the rubber ball 100 can pass through the ball serving channel 103 and enter the inside of the water inlet pipe 1.

Specifically, the partition component 5 can guide part of the water flow into the first ball storage chamber through the water taking channel 102, the rubber balls 100 in the first ball storage chamber are pushed by the water flow and pass through the ball serving channel 103 to enter the water inlet pipe 1, the rubber balls 100 flowing from the heat exchange pipe to the water outlet pipe 2 are guided by the first filter screen 4 to pass through the ball receiving channel 203 and are recovered to the second ball storage chamber, when all the rubber balls 100 are completely recovered to the second ball storage chamber 100, the inner barrel component can be driven to switch to another ball receiving and serving state, the water flow enters the second ball storage chamber from the water taking channel 102, and the rubber balls 100 in the second ball storage chamber are pushed by the water flow and pass through the ball serving channel 103 to enter the water inlet pipe 1.

The first filter screen 4 of this embodiment can guide glueballs 100 to get into from the inside ball receiving channel 203 that gets into of outlet pipe 2, finally gets into first ball storage chamber or second ball storage chamber, avoids glueballs 100 to pile up for a long time at first filter screen 4, causes interim water resistance to increase or makes glueballs 100 accelerated wear.

The water flow in the water inlet pipe 1 is cooling water with a large pressure, the moving power of the rubber ball 100 is derived from the pressure difference of the cooling water, and when too many through holes are formed in the inner cylinder or the outer cylinder, the risk of water leakage or water channeling is increased. Therefore, in the embodiment, the first interface 101 and the second interface 201 are coaxially arranged, the first connection hole 341 and the second connection hole 342 are coaxially arranged, and no matter the inner barrel is in a switching state or a holding state, the central axis of the first interface 101, the central axis of the first connection hole 341, the central axis of the second interface 201 and the central axis of the second connection hole 342 are always located on the same plane, so that the risk of water leakage or water channeling is reduced.
