Description
Improved channel cleaning system
Technical Area
The present invention relates to a cleaning system for cleaning the interior of a channel using movable cleaning elements.
In many cases, an apparatus in which curved channels are arranged is needed to achieve a certain function, and the most common apparatus is a heat exchanger.
In order to prevent dirt or other undesirable subsidence from being generated when fluid is flowing in these curved channels and depositing on the inner of the channel, various methods are proposed to clean the inner wall of the channels described above.
The most common method available is to use cleaning balls made of rubber or sponge material, the diameter of which is slightly larger than that of the channels to be cleaned, and when the cleaning balls are moving in the channels along with the fluid, these cleaning balls will be compressed. The purpose for cleaning the inner wall of the channels will be achieved using the friction between these compressed cleaning balls and the inner walls of the channels.
Generally, the cleaning balls and the fluid pass through the channels from its upstream end to its downstream end towards the direction of the fluid flow. An improved cleaning system as disclosed in Chinese patent document
CN100424461C is shown in Fig. 7, and the system comprises a channel (100) which is used to guide fluid through and is connected to an inlet tube (110) and an outlet tube (120). a ball collector (130), which is separated into a first chamber (132) and a second chamber (133) by an isolating plate with holes (131), with a certain number of elastic cleaning balls (134) being provided in the first chamber
(132), and only the fluid instead of the elastic cleaning balls (134) being allowed by the first isolating plate with holes (131) to flow from the first chamber (132) into the second chamber (133); a ball receiver (122) which is provided on an upstream end (121) of the outlet tube (120), characterized in that the ball receiver (122) is used to separate the elastic cleaning balls (134) from the fluid, with the ball receiver (122) including a filter screen (1221), which only allow the fluid instead of the elastic cleaning balls (134) to flow through; a piece of fluid supply tube (140), with a first valve (V1) being cascaded therein, an inlet end (141) of the fluid supply tube (140) being located on an upstream end (111) of the inlet tube 110, and an outlet (142) of the fluid supply tube (140) being connected to the first chamber (132) of the ball collector (130); a piece of elastic cleaning ball supply tube (150), with a first one-way valve (CV1) being cascaded therein, and the first one-way valve (CV1) only allowing the fluid and the elastic cleaning balls (134) within the first chamber (132) to discharge from the first chamber (132), an inlet end (151) of the elastic cleaning ball supply tube (150) being connected to the first chamber (132), an outlet end (152) of the elastic cleaning ball supply tube (152) being connected to the downstream end (112) of the inlet tube (110), and the elastic cleaning balls (134) being brought into the inlet tube (110) using a fluid pressure difference between the inlet end (141) of the fluid supply tube (140) and the inlet end (151) of the elastic cleaning ball supply tube (150); a piece of fluid return tube (160), with a second valve (V2) being cascaded therein, the inlet end (161) of the fluid return tube (160) being connected to the second chamber (133), and the outlet end (162) of the fluid return tube (160) being connected to the downstream end (123) of the outlet tube (120), a piece of elastic cleaning ball return tube (170), with a second one-way valve (CV2) being cascaded therein, and only the elastic cleaning balls and the fluid being allowed by the second one-way valve (CV2) to flow into the first chamber (132), the inlet end (171) of the elastic cleaning ball return tube being connected to the outlet of the filter screen (1221), the outlet end (172) of the elastic cleaning ball return tube being connected to the first chamber (132), and the clastic cleaning balls (134) returning to the first chamber (132) using the fluid pressure difference between the filter screen (1221) and the outlet (162) of the fluid return tube (160) when the first valve (V1) is closed. This cleaning system has the advantage that as long as two valves, i.e., on or off of the first valve (V1) and the second valve (V2), are controlled, the cleaning of the channel (100) or the collection of the elastic cleaning balls (134) can be achieved conveniently. However, the fluid supply tube (140) and the elastic cleaning ball supply tube (150) are connected to the first chamber (132) in particular the same side of the ball collector (130) by this cleaning system, thus it is inevitable that after the fluid flows from the fluid supply tube (140) into the first chamber (132), the elastic cleaning balls (134) can be brought into the inlet tube (110), only if the fluid supply tube (140) is bent 360 degrees, which cause the flow of the elastic cleaning balls (134) to be blocked and not smooth. The second problem is that the fluid supply tube (140), the elastic cleaning ball supply tube (150), the fluid return tube (160) and the elastic cleaning return tube (170) of this cleaning system are all connected to the ball collector (130) individually, thus not only resulting in much more failure points, but also bring inconvenience to the field installation. summary of the invention

Compared to the embodiment shown in Fig. 2, Fig. 4 has essentially the same structure, and the only difference is that an extension line of an axle wire (33) of the outlet tube (30) connected to the housing (52) of the ball collector (50) is perpendicular to an extension line of an axle wire (53) of the housing (52) of the ball collector (50). This structure is particularly suited to the situation that the inlet tube (20) and the outlet tube (30) need to be piped upward because the system is lack of assembly space, and using the structure of the ball receiver with a “L” shaped opening, this system can be assembled in a relative small space. In addition, a detachable maintenance window (54) is added at the back end of the ball receiver (50), and the filter screen (51) is designed as a detachable structure, such as slip type structure, and in this way, when the filter screen (51) need to be maintained, it can be convenient to maintain from this maintenance window (54).

A supporting bar (492) is provided under the drain tube (49), with the supporting bar (492) fixed to the floor (493). A funnel-shaped outlet (47) is provide under the ball receiver, which has the function of generating a number of sundries and chips of the elastic cleaning balls (44) when the cleaning system is in a long term operation process, and these chips will flow through the first isolating plate with holes (41) and the second isolating plate with holes (48) to deposit, and be cleaned regularly and manually through the drain tube.
Referring to Fig. 5, the present invention can further be designed as an improved channel cleaning system, with a channel (10) being used to guide fluid through and being connected to one inlet tube (20) and one outlet tube (30), wherein, the system comprising: a ball collector (40), characterized in that the ball collector (40) is separated into a first chamber (42) and a second chamber (43) by a first isolating plate with holes (41), with a certain number of elastic cleaning balls (44) being provided in the first chamber (42), and only the fluid instead of the elastic cleaning balls (44) being allowed by the first isolating plate with holes (41) to flow from the first chamber (42) to the second chamber (43);
a ball receiver (50) which is provided on an upstream end (31) of the outlet tube (30), characterized in that the ball receiver (50) is used to separate the elastic cleaning balls (44) from the fluid, with the ball receiver (50) including a filter screen (51), which only allow the fluid instead of the elastic cleaning balls (44) to flow through;
a piece of fluid supply tube (60), a piece of cleaning ball supply tube (70), a piece of fluid return tube (80) and a piece of elastic cleaning ball return tube (90); characterized in that an outlet tube (61) of the fluid supply tube (60) is connected to the second chamber (43) of the ball collector (40) by a first T-shaped tube (62), with an inlet end (63) of the fluid supply tube (60) being located within the upstream end (21) of the inlet tube (20), and the nozzle direction of the inlet end (63) of the fluid supply tube (60) is opposite to the direction of the fluid flow (F1), a first valve (65) being cascaded in the pipe (64) of the fluid supply tube (60) which resides between the first T-shaped tube (62) and the inlet end (63) of the fluid supply tube (60);
an inlet end (71) of the elastic cleaning ball supply tube (70) is connected to the first chamber (42) of the ball collector (40), and an outlet end (73) of the elastic cleaning ball supply tube (70) is connected to the downstream end (22) of the inlet tube (20), with a first one-way valve (74) being cascaded in the elastic cleaning ball supply tube (70), and only the fluid and the elastic cleaning balls (44) being allowed by the first one-way valve (74) to discharge from the ball collector (40);
an inlet end (81) of the fluid return tube (80) is connected to a first T shaped tube (62), and an outlet end (82) of the fluid return tube (80) is connected to the downstream end (32) of the outlet tube (30) which is connected to the back end of the ball collector (50), with a second valve (83) being cascaded in the fluid return tube (80); an inlet end (91) of the elastic cleaning ball return tube (90) passes through the housing (52) of the ball collector (50) and is connected to the outlet end of the filter screen (51) being located within the housing (52) of the ball collector (50), and an outlet end (92) of the elastic cleaning ball return tube (90) is connected to the first chamber (42) of the ball collector (40), with a second one-way valve (93) being cascaded in the elastic cleaning ball return tube (90), and only the fluid and the elastic cleaning balls (44) being allowed by the second one-way valve (93) to flow into the ball collector (40).
Compared to the embodiment shown in Fig. I, this cleaning system has essentially the same structure, and the only difference is that the elastic cleaning ball supply tube (70) and the elastic cleaning ball return tube (90) are connected to the first chamber (42) directly instead of using the second T-shaped tube (72), which illustrates that the present invention has a more flexible assembly structure.
The first valve (64) and the second valve (83) both can be controlled by a
PLC controller (not shown) when the present invention is in actual use. When the
PLC controller is working, it drives the first valve (64) and opens the first valve (64) to enable the fluid to flow through, while closes the second valve (83) to prohibit the fluid from flowing through. At this point, the first one-way valve (74) is opened, the second one-way valve (93) is closed, and after the fluid flows from the fluid supply tube (60) into the ball collector (40), the elastic cleaning balls (44) are sent to the first one-way valve (74), thus enabling the elastic cleaning balls (44) to enter into the channel (10) needed to be cleaned. After 3 io 10 seconds, the PLC controller closes the first valve (64) to prohibit the fluid from flowing through while the PLC controller opens the second valve (83) to enable the fluid to flow through. At this point, the elastic cleaning balls (44) flow from the ball receiver (50) into ball collector (40) under the push of the fluid. And because the first one-way valve (74) is closed under the positive pressure and there are isolating effects of the first isolating plate with holes (41) and the second isolating plate with holes (48), the elastic balls (44) can only stay in the ball collector (40). After 3 to 10 minutes, the PLC controller closes the second valve (83) to prohibit the fluid from flowing through and the overall cleaning system completes this cleaning.
The first T-shaped tube (62) and the second T-shaped tube (72) in the present invention each refer to a T-shaped three-way.
