In order to further enrich the functions of the whole system, especially to create conditions for the ventilation test of the pipeline before cleaning to judge whether the workpiece circulating pipeline is blocked, as shown in fig. 11 to 13, the second water delivery on-off connecting pipe in the embodiment comprises a second channel flow collecting block E101 which is in a cuboid structure as a whole, a driving cylinder assembly E102 which is arranged on the left side wall or the right side wall of the second channel flow collecting block E101 and outputs power along the front-back direction of the second channel flow collecting block E101, and a plurality of (such as four) air injection valves E103 which are arranged on the back side wall of the second channel flow collecting block E101 and are arranged side by side up and down; a second water channel E104 which is distributed along the vertical direction and one end of which is communicated with a third water conveying pipeline L103, a cylinder opening air channel E105 which is communicated with an opening chamber of the driving cylinder assembly E102, a cylinder closing air channel E106 which is communicated with a closing chamber of the driving cylinder assembly E102 and a plurality of second fluid circulation channels E107 which are communicated with the second water channel E104 and are positioned at the front end side of the second channel flow collecting block E101 are arranged in the second channel flow collecting block E101, and a second fluid nozzle E108 penetrates through each second fluid circulation channel E107; the second fluid circulation channels E107 correspond to the air injection valves E103 one by one (namely, each second fluid circulation channel E107 and the corresponding second fluid nozzle E108 are provided with one air injection valve E103 in a one-to-one alignment manner), the body of each air injection valve E103 is arranged on the power shaft of the driving cylinder assembly E102, the valve core is arranged in the corresponding second fluid nozzle E108 in a penetrating manner through the second water channel E104, the air inlet of each air injection valve E103 is connected with a second electromagnetic switch valve D107 and a pressure sensor G15 through a corresponding eighth air transmission pipeline S108, all the second electromagnetic switch valves D107 and the corresponding pressure sensors G15 are simultaneously connected with the air outlet of the air storage tank P1 through a ninth air transmission pipeline S109, and the eighth air transmission pipeline S108 is provided with a second electromagnetic switch valve D107 and a pressure sensor G15; correspondingly, the first air transmission pipeline S101 is further provided with a fourth three-way electromagnetic valve D108, one outlet of the fourth three-way electromagnetic valve D108 is connected with the cylinder opening air passage E105 through a tenth air transmission pipeline S110, and the other outlet is connected with the cylinder closing air passage E106 through an eleventh air transmission pipeline S111; the second electromagnetic switch valve D107, the fourth three-way electromagnetic valve D108 and the pressure sensor G15 are respectively connected with a system centralized controller; in addition, the first water supply on-off connecting pipe comprises a first channel flow collecting block E109, a first waterway channel which is distributed along the vertical direction and one end of which is communicated with the first water supply pipeline L101 and a plurality of first fluid circulation channels which are communicated with the first waterway channel and are positioned at the front end side of the first channel flow collecting block E109 are arranged in the first channel flow collecting block E109, a first fluid nozzle E110 is arranged in each first fluid circulation channel in a penetrating way, and the first fluid circulation channels are the same in number with the second fluid circulation channels E107 and are in one-to-one correspondence.

Therefore, the second fluid nozzle E108 and the second water channel E104 can be isolated by using the inserting and sleeving relation between the valve core (which may adopt a structure similar to a tube) of the air injection valve E103 and the second fluid nozzle E108, and the second water channel E104 and the second fluid nozzle E108 can be conducted after the valve core is drawn away from the second fluid nozzle E108; when the ventilation detection is carried out on the workpiece circulating pipeline, a system centralized controller can be used for opening a pipeline which flows back to a water storage tank T1 or a backwater material separation tank through a first water delivery on-off connecting pipe in advance, then the second electromagnetic switch valve D107 is used for opening to charge air into the air injection valve E103, so that compressed air enters the workpiece circulating pipeline through the valve core and the second fluid nozzle E108, and in the process, the pressure sensor G15 can be used for detecting the gas pressure in real time, so that data support is provided for judging whether the workpiece circulating pipeline is blocked or not; when the pipeline is flushed, the driving cylinder assembly E102 is opened by controlling the fourth three-way solenoid valve D108 by the system centralized controller, so that the driving cylinder assembly E102 can drive the air injection valve E103 to move backward relative to the second channel manifold block E101, and the valve core is pulled away from the second fluid nozzle E108 to communicate the second fluid nozzle E108 with the second water channel E104, thereby performing flushing operation; in addition, a plurality of fluid nozzles can be arranged to connect a plurality of workpiece circulating pipelines at one time.

In order to enrich the practical functions of the whole system to the maximum extent, the gas outlet of the gas storage tank P1 of the present embodiment is also communicated with the third water conveying pipeline L103 and the ninth water conveying pipeline L109 through a large flow gas conveying pipeline S112, a large flow electromagnetic switch valve D109 and a gas one-way check valve F12 are sequentially arranged on the large flow gas conveying pipeline S112 and along the flow direction of the gas flow, wherein the large flow electromagnetic switch valve D109 is in control connection with the system centralized controller. Therefore, after the cleaning operation of the workpiece circulating pipeline is completed, the forward flushing channel or the reverse flushing channel can be conducted by controlling the corresponding valve by the system centralized controller (note that the cleaning water pump B1 does not need to be started at the moment), and meanwhile, the large-flow electromagnetic switch valve D109 is opened so that the compressed air in the air storage tank P1 can finally enter the workpiece circulating pipeline through the large-flow air pipeline S112, and therefore the accumulated water remained in the workpiece circulating pipeline is discharged at one time by the large-flow air, and the air drying effect of the pipeline is achieved.

In order to realize the real-time detection of the steel ball storage quantity in the ball storage barrel so as to provide support for executing forward flushing or backward flushing, an upper limit steel ball liquid level sensor G11 and a lower limit steel ball liquid level sensor G12 are respectively arranged on the first steel ball storage barrel Q11 and the second steel ball storage barrel Q12, and the upper limit steel ball liquid level sensor G11 and the lower limit steel ball liquid level sensor G12 are respectively connected with a system centralized controller.

In order to detect the flow of fluid in the workpiece circulating pipeline in real time before and after the cleaning operation and determine the comparison effect between the flow before and after the operation, the water outlet of the backwater material separation tank is also connected between the water outlet of the cleaning water pump B1 and the upstream of the waterway one-way check valve F11 through a fourteenth water pipeline L114, and a first electromagnetic switch valve D106 is arranged on the fourteenth water pipeline L114; correspondingly, a pipe pressure sensor G13 is arranged on the third water conveying pipeline L103 and adjacent to the water outlet of the cleaning water pump B1, a flow sensor G14 is arranged on the second water conveying pipeline L102, and the first electromagnetic switch valve D106, the flow sensor G14 and the pipe pressure sensor G13 are respectively connected with a system centralized controller; therefore, the flow sensor G14 can be used for detecting the fluid flow in the workpiece circulation pipeline before or after the cleaning operation, and the difference between the workpiece circulation pipeline before and after the operation can be judged according to the detected data; meanwhile, by matching the fourteenth water conveying pipeline L114 with the first electromagnetic switch valve D106, water flow jetting can be performed on the backwater substance separation tank, so that substances (particularly steel balls) accumulated in the backwater substance separation tank smoothly enter the corresponding pill storage barrel.

In order to realize effective separation of the components of the mixed fluid discharged from the workpiece circulation pipeline, as shown in fig. 10, the backwater substance separation tank of the embodiment includes a backwater tank body H11, a specific gravity baffle H14 disposed in the backwater tank body H11 to separate the tank body space of the backwater tank body H11 into a steel shot collecting tank H12 and an impurity filtering tank H13 which are mutually distributed in parallel, and a steel ball filtering funnel H15 disposed at the bottom of the steel shot collecting tank H12 and used as a water outlet of the backwater substance separation tank; meanwhile, a first water conveying pipeline L101 is communicated with the steel shot collecting tank H12 (namely, a water inlet of the backwater substance separating tank is arranged in the steel shot collecting tank H12), the impurity filtering tank H13 is also connected with a backwater port of the water storage tank T1 through a fifteenth water conveying pipeline L115, and an upper limit steel ball induction switch G16 connected with a system centralized controller is further arranged on the backwater tank body H11 and positioned at the upper end of the steel ball filtering funnel H15.

Therefore, in the actual use process of the system, because the mixed fluid discharged from the workpiece circulating pipeline mainly comprises water, steel balls and impurities (such as settled sand, rusty spots, water scales and the like), the characteristics of density difference between the water, the steel balls and the impurities can be utilized to separate the two components through the specific gravity baffle plate H14, namely: after the mixed fluid enters the steel ball collecting tank H12 through the first water conveying pipeline L101, the steel balls sink into the steel ball filter funnel H15 due to the fact that the density of the steel balls is larger than that of water, and finally enter the ball storage barrel along with water flow, impurities floating on the water are shunted to the impurity filter tank H13 along with the water flow through the specific gravity baffle plate H14, at the moment, a corresponding filter screen can be arranged in the impurity filter tank H13 to enable the impurities to be deposited on the filter screen, and the water flows back to the water storage tank T1 through the fifteenth water conveying pipeline L115, so that the effect of complete material separation is achieved.

In addition, according to different use modes, the cleaning system of the embodiment can be arranged in the operation site in advance in a distributed pipeline arrangement mode, but as a preferable scheme, in order to enhance the moving performance of the cleaning system so that the cleaning system can exist and be used in the form of independent machine equipment (namely, the cleaning system according to the embodiment forms a pipeline cleaning machine as shown in fig. 4 and 5), a main machine shell J11 with wheels can be used for packaging a water storage tank T1, a backwater substance filter tank, a cleaning water pump B1, a first steel ball pill storage barrel Q11, an air storage tank (P1) and corresponding pipelines into a whole; wherein, the end part of the first water delivery on-off connecting pipe and the end part of the second water delivery on-off connecting pipe are preferably ensured to penetrate through the rear wall surface of the main machine shell J11 so as to be convenient for connecting or disconnecting the on-off connecting pipe with the workpiece circulating pipeline, thereby forming the integrated cleaning machine; certainly, in order to facilitate the operation of the whole cleaning machine, according to actual conditions, a human-computer interaction display screen J12, an operating state indicator light, an on-off and mode switching button and the like of the system centralized controller can be installed on the front wall surface of the main machine casing J11, and meanwhile, auxiliary components such as a ventilation fan J13 and the like can be arranged on the main machine casing J11 so as to dissipate heat of electronic elements or heat generating devices and the like in the main machine casing J11 in real time.

Based on the structure and function of the whole cleaning system, the whole system can be specifically designed (for example, the system centralized controller can perform corresponding program editing by referring to the following modes) or used in the following modes:

before cleaning the workpiece circulation pipe, the first and second water supply on-off connection pipes may be butted against both ends of the workpiece circulation pipe by using a pipe connection member such as a quick coupling, and the pipe pressure sensor G13 and the flow sensor G14 are simultaneously turned on, and then the following operation steps are sequentially performed:

1. and (2) water path ventilation detection operation (the operation process is mainly used for detecting whether a workpiece circulation pipeline to be cleaned has cleaning conditions or not so as to avoid pipeline breakage or damage to the whole cleaning system caused by forced cleaning).

Firstly, the system centralized controller outputs a control signal to open a first three-way electromagnetic valve D103 to open first outlets of a first ball valve K101, a third ball valve K103, a fifth ball valve K105, a seventh ball valve K107 and a three-way switch ball valve K111; then, a control signal is output to open a second electromagnetic switch valve D107 so as to convey gas into the workpiece circulation pipeline through a second fluid nozzle E108 and keep the gas for a certain time (such as 15 s); at the moment, if the pressure parameter detected by the pressure sensor G15 exceeds the upper limit value (such as 0.35Mpa) and is kept for a certain time (such as 3s), the system centralized controller can send out a blockage alarm prompt corresponding to the water channel through a human-computer interaction display screen J12 or a working state indicator lamp and the like, then the system is stopped from running, and another workpiece circulation pipeline is replaced or the pipeline is subjected to filling treatment; if the pressure parameter detected by the pressure sensor G15 does not exceed the upper limit, it is verified that the pipe is not severely plugged, the system is stopped after a certain period of operation (e.g., 24s), and the system centralized controller records the last pressure parameter for use as the basis for the ventilation test report.

2. The flow rate detection operation before cleaning (the operation process is mainly to obtain the pipe condition of the workpiece circulation pipe to be cleaned, and simultaneously, the detected flow rate data is used as basic data for calculating the opening degree of the proportional control valve), and the operation process can preset constant water pressure (such as 0.3 MPa).

Firstly, the system centralized controller outputs a control signal to start the cleaning water pump B1 and simultaneously start the first three-way electromagnetic valve D103 to open the first outlets of the first ball valve K101, the third ball valve K103, the fifth ball valve K105, the seventh ball valve K107 and the three-way switch ball valve K111; at this time, water flow output by the water storage tank T1 finally flows back to the water storage tank T1 through the backwater substance separation tank and the second steel ball pill storage barrel Q12 along corresponding pipelines, and after the system operates for a certain period of time (for example, 20s) and the flow sensor G14 can detect a stable flow parameter, the system centralized controller records the flow parameter and calculates the opening degrees of the first electric proportional control valve M11 and the second electric proportional control valve M12 according to the flow parameter; and finally, stopping the operation.

3. The method comprises the following steps of performing primary high-pressure washing operation (the operation process is mainly to pre-wash a workpiece circulating pipeline to wash out large foreign matters or loose scales in the pipeline, enabling impurities with the density higher than that of water to flow into a corresponding shot storage barrel through a steel shot collecting tank H13 and a steel shot filtering funnel H15 after foreign matters and impurities with the density lower than that of water flow back into a backwater substance separating tank along with water flow, separating the impurities into an impurity filtering tank H13 and finally cleaning the impurities, and the operation process can preset the maximum water pressure to be 1.5 MPa).

Firstly, the system centralized controller outputs a control signal for forward flushing, namely: opening a cleaning water pump B1 and simultaneously opening a first three-way electromagnetic valve D103 to open first outlets of a first ball valve K101, a third ball valve K103, a fifth ball valve K105, a seventh ball valve K107 and a three-way switch ball valve K111; the water flow output by the water storage tank T1 will flow back to the system through the second fluid nozzle E108, the workpiece circulating pipeline and the first fluid nozzle E110 in sequence under the action of the cleaning water pump B1, in the process, the water in the pipeline can flow at high speed (for example, the flow speed is 12-15m/s) through the set maximum water pressure, and the operation is stopped after a certain period of operation (for example, 15 s); then, the system centralized controller outputs a control signal for back flushing, namely: the cleaning water pump B1 is started, and the first three-way electromagnetic valve D103 is started at the same time, so that the second outlets of the second ball valve K102, the fourth ball valve K104, the sixth ball valve K106, the eighth ball valve K108 and the three-way switch ball valve K111 are opened, water flow output by the water storage tank T1 sequentially flows back into the system at a high speed through the first fluid nozzle E110 workpiece circulation pipeline and the second fluid nozzle E108 under the action of the cleaning water pump B1, and stops operating after operating for a certain time (such as 15 s); thereby completing one high pressure flushing operation.

4. And (4) carrying out high-pressure steel shot mixing and cleaning operation (the maximum water pressure can be preset to be 1.5 Mpa).

Firstly, the centralized controller outputs a control signal for forward cleaning, namely: opening a cleaning water pump B1 and simultaneously opening a first three-way electromagnetic valve D103 to open first outlets of a first ball valve K101, a third ball valve K103, a fifth ball valve K105, a seventh ball valve K107 and a three-way switch ball valve K111; opening the second three-way solenoid valve D104 to open the ninth ball valve K109; after the preset time (such as 5s), opening the first electric proportional control valve M11 and the first differential pressure solenoid valve D101; at this time, the high-speed mixed fluid discharged from the second fluid nozzle E108, which is a mixture of water and steel balls discharged from the first steel ball storage tub Q11, is removed by the impact effect of the high-speed mixed fluid with the inner wall of the workpiece circulation pipe in all directions, and the high-speed mixed fluid flowing back thereafter enters the steel ball collecting tank H12 first, so that such as steel balls having a density higher than that of water are sunk into the steel ball collecting tank H12 and finally enters the second steel ball storage tub Q12 via the steel ball filtering funnel H15 under the action of the specific gravity baffle H14 and by the difference in density between substances, and such as impurities having a density lower than that of water flow through the specific gravity baffle H14 into the impurity filtering tank H13 (in this process, a part of the excess water flows into the water storage tank T1 via the impurity filtering tank H13, and another part of the excess water flows into the water storage tank T1 via the second steel ball storage tub Q12, when the upper limit steel ball inductive switch G16 detects that the steel ball stacking height in the steel ball filter funnel H15 exceeds the upper limit height, the system stops operating and the first ball outlet channel of the first ball storage barrel Q11 is closed by the first electric proportional control valve M11, then the first electromagnetic switch valve D106 is opened to smoothly guide the steel balls into the second steel ball storage barrel Q12 by water flow, when the stacking height of the steel balls is lower than the upper limit height, the actions are continuously executed, in the process of flushing, all the on-line steel ball liquid level sensors G11 and the lower limit liquid level sensor G12 are always kept in an on state, when the steel ball amount in the first steel ball pill storage barrel Q11 is detected to be lower than the lower limit value or the steel ball amount in the second steel ball pill storage barrel Q12 is detected to be higher than the upper limit value, it is verified that the balls have substantially all flowed back into the second ball hopper Q12 and the system stops performing the forward purge.

Then, the system starts again and performs a back flush, i.e.: the system centralized controller outputs a control signal to start the cleaning water pump B1 and simultaneously starts the first three-way electromagnetic valve D103 to open the second outlets of the second ball valve K102, the fourth ball valve K104, the sixth ball valve K106, the eighth ball valve K108 and the three-way switch ball valve D111; and (3) opening the third three-way solenoid valve D105 to open the tenth ball valve K110, and opening the second proportional control valve M12 and the second differential pressure solenoid valve D102 after a preset time (for example, 5s), wherein the high-speed mixed fluid formed by mixing water and steel balls from the second steel ball storage barrel Q12 flows out of the first fluid nozzle E110, so that the related action is realized according to the forward flushing principle, and the reverse flushing operation is completed.

In the process of high-pressure steel shot mixed cleaning operation, the problems of good flushing effect of one side flow direction and poor flushing effect of the other side flow direction of the inner wall of the pipeline can be effectively avoided by executing forward flushing and backward flushing; of course, the number of forward and backward flushes can be set according to practical situations.

5. And (2) performing secondary high-pressure washing operation (the operation process is the same as the primary high-pressure washing operation process, and the main action is to completely recycle the residual steel balls in the pipeline into the first steel ball pill storage barrel Q11 or the second steel ball pill storage barrel Q12 so as to reduce the loss of the steel balls).

6. And (2) post-cleaning flow detection operation (the operation process is the same as the flow detection operation process before cleaning, and mainly functions to acquire flow data of the workpiece circulation pipeline after cleaning, so that basis is provided for visually embodying the post-cleaning effect by comparing the flow difference between the pre-cleaning and post-cleaning parts).

7. And (2) draining and air drying operation (the operation process mainly has the function of draining accumulated water in the pipeline back to the water storage tank T1 so as to reduce the loss of circulating water, prevent the pipeline wall from rusting and prevent liquid from flowing out when a workpiece is disassembled to ensure that the operation environment is clean).

The system centralized controller outputs a control signal to open the first three-way electromagnetic valve D103 to open the first outlets of the first ball valve K101, the third ball valve K103, the fifth ball valve K105, the seventh ball valve K107 and the three-way switch ball valve K111, then opens the large-flow electromagnetic switch valve D109 to make the compressed air in the air storage tank P1 enter the circulation pipeline, so that the accumulated water in the workpiece circulation pipeline is discharged into the cleaning system through the first fluid nozzle E110 by using large-flow gas and finally flows back to the water storage tank T1, and the air drying treatment of the inner wall of the pipeline can be simultaneously completed by controlling the duration of ventilation.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
