Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a valve block oil circuit cleaning device. Background Technology

[0002] Valve blocks are widely used in machinery. Whether newly manufactured or old, hydraulic valve blocks must be cleaned after maintenance before use. Currently, kerosene or gasoline is commonly used for cleaning.

[0003] Chinese utility model patent with authorization publication number CN206810750U discloses a valve block oil circuit cleaning device. According to its instruction manual, when cleaning the valve block, cleaning oil is injected into the box, two processed valve blocks are placed on the filter sponge, the nozzle on the hose is aligned with the oil port of the valve block, and the pressure of the oil port pressure regulating device is adjusted to the minimum pressure position; the electrical switch in the electrical box is turned on to start the two oil pumps and clean the valve block.

[0004] However, the cleaning devices in the aforementioned patents have the following main problems: (1) such as Figure 7 As shown, this is a schematic diagram of a valve block with several ports. Each port may be connected by an irregularly shaped channel inside the valve block. If the cleaning medium is sprayed into one port through a single nozzle, the cleaning medium may have difficulty reaching other ports, and multiple ports cannot be cleaned simultaneously, thus reducing cleaning efficiency and quality. (2) After inserting the nozzle into the port of the valve block, the nozzle sprays the cleaning medium into the valve block. Due to the recoil force, the nozzle is prone to detach from the port, affecting the cleaning of the valve block. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a valve block oil circuit cleaning device head to solve the problem that multiple pipe ports cannot be cleaned simultaneously when cleaning valve blocks.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A valve block oil circuit cleaning device includes a frame, a cleaning box with top and front openings connected to the upper end of the frame, a filter plate at the lower part of the cleaning box, a storage tank for storing cleaning medium installed on the frame, a conveying mechanism for conveying the cleaning medium in the storage tank upwards on the frame, and a flushing mechanism installed at the end of the conveying mechanism; the flushing mechanism includes a main pipe, a box connected to the lower end of the main pipe, multiple connecting pipes connected to the bottom of the box, a flexible hose connected to the lower end of the connecting pipes, a spray pipe connected to the flexible hose, and a nozzle connected to the spray pipe. A first ball valve is installed on each connecting pipe. The flushing mechanism also includes multiple positioning plates fixedly connected to the top of the box, and the top of the positioning plate has a U-shaped groove for locking the spray pipe. The main pipe is connected to the conveying mechanism.

[0008] Preferably, the conveying mechanism includes an oil pump, a check valve, a first pipe, and a second pipe. The oil pump is mounted on a frame. The lower part of the storage tank is connected to the check valve and the inlet end of the oil pump in sequence through the first pipe. The outlet end of the oil pump is connected to the main pipe through the second pipe. A second ball valve is installed on both the first pipe and the second pipe.

[0009] The above technical solution involves starting the oil pump, which extracts the cleaning medium from the storage tank and, after passing through a check valve, conveys it upwards to the rinsing mechanism. The check valve prevents backflow of the cleaning medium. A second ball valve controls the opening and closing of both pipelines.

[0010] Preferably, the storage box is provided with a vertical partition, one side of which is a sludge collection chamber and the other side is a storage chamber. The bottom of the cleaning box is connected to a discharge pipe for cleaning medium, which is connected to the sludge collection chamber. The lower part of the storage box is connected to a drain pipe that is connected to the sludge collection chamber. The upper part of the storage box is provided with an injection pipe for adding cleaning medium into the storage chamber.

[0011] In the above technical solution, the waste cleaning medium is filtered by the filter plate, enters the sludge collection chamber through the discharge pipe, and is then discharged through the sewage pipe and recycled by additional recycling equipment.

[0012] Preferably, a level gauge is provided on one side of the storage chamber of the storage tank.

[0013] The above technical solution allows the level of the cleaning medium in the storage chamber to be observed using a level gauge.

[0014] Preferably, the front opening of the cleaning tank is provided with slots on both sides, and baffles are inserted into the slots.

[0015] In the above technical solution, after the valve block is placed in the cleaning tank, the baffle is inserted through the slot. The baffle can prevent the cleaning medium from splashing outwards during cleaning.

[0016] Preferably, the outer wall of the nozzle is connected to a conical rubber sleeve.

[0017] In the above technical solution, the rubber sleeve is conical, with the diameter of its upper end being larger than that of its lower end. When the nozzle is inserted into the valve block's inlet, the rubber sleeve is elastic and has a certain degree of damping, thus securing it tightly within the inlet and preventing the nozzle from falling out under the action of recoil force. Furthermore, the rubber sleeve also helps to stably hold the nozzle within the U-shaped groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The valve block is placed on the filter plate. Depending on the number of ports on the valve block, different nozzles can be inserted into the ports. Then, the corresponding first ball valve is opened, and the cleaning medium is sent to the main pipe through the conveying mechanism. Finally, it is sprayed out by the nozzles to clean the ports and the internal pipeline of the valve block. Unused nozzles remain stuck on the positioning plate, which facilitates storage and does not obstruct the rinsing of the valve block.

[0020] A rubber sleeve is installed around the nozzle, and the rubber sleeve is conical, that is, the diameter of the upper end is larger than the diameter of the lower end. When the nozzle is inserted into the nozzle of the valve block, the rubber sleeve is elastic and has a certain damping, so it can be tightly locked in the nozzle and prevent the nozzle from falling out of the nozzle under the action of recoil force.

A vertical partition 7 divides the storage tank 4 into two independent areas: one side of the partition 7 is a sludge collection chamber 8, and the other side is a storage chamber 9. A discharge pipe 10 for the cleaning medium is connected to the bottom of the cleaning tank 2, communicating with the sludge collection chamber 8. A drain pipe 11 communicating with the sludge collection chamber 8 is connected to the lower part of the storage tank 4. The cleaned medium is filtered by the filter plate, then enters the sludge collection chamber 8 through the discharge pipe, and finally is discharged through the discharge pipe 10 and sent to additional medium recovery or treatment equipment.

[0032] The upper part of the storage box 4 is provided with an injection pipe 12 for adding cleaning medium into the storage cavity 9. Clean cleaning medium can be added into the storage cavity through the injection pipe 12.

[0033] The frame 1 is provided with a conveying mechanism 5 for conveying the cleaning medium in the storage tank 4 upwards, and a rinsing mechanism 6 is installed at the end of the conveying mechanism 5.

[0034] The conveying mechanism 5 includes an oil pump 501, a check valve 502, a first pipe 503, and a second pipe 504. The oil pump 501 is mounted on the frame 1. The first pipe 503 is connected to one side of the lower part of the storage tank 4. The first pipe 503 is connected to the storage chamber 9. The first pipe 503 is connected to the check valve 502 and the inlet end of the oil pump 501 in sequence. The outlet end of the oil pump 501 is connected to the second pipe 504. The second pipe 504 is connected to the flushing mechanism 6. A second ball valve 505 is installed on both the first pipe 503 and the second pipe 504.

[0035] The rinsing mechanism 6 includes a main pipe 601, a housing 602 connected to the lower end of the main pipe, multiple connecting pipes 603 connected to the bottom of the housing, a flexible hose 604 connected to the lower end of the connecting pipes, a spray pipe 605 connected to the hose, and a nozzle 606 connected to the spray pipe. The main pipe 601, housing 602, and connecting pipes 603 are sequentially connected, and the main pipe 601 and housing 602, as well as the housing 602 and connecting pipes 603, are sealed together. Each connecting pipe 603 is equipped with a first ball valve 607 for controlling the opening and closing of the connecting pipe 603. The rinsing mechanism 6 also includes multiple positioning plates 608 fixedly connected to the top of the housing. The top of each positioning plate 608 has a U-shaped groove for locking the spray pipe.

[0036] A level gauge 13 is installed on one side of the storage chamber of the storage tank 4. The level gauge allows observation of the level of the cleaning medium in the storage chamber.

[0037] The front opening of the cleaning tank 2 is provided with slots 14 on both sides, and baffles 15 are inserted into the slots 14. After the valve block is placed in the cleaning tank, the baffles 15 are inserted into the slots 14. The baffles 15 can prevent the cleaning medium from splashing outward during cleaning.

[0038] This embodiment also includes a controller, a start button, etc., and the oil pump and start button are electrically connected to the controller. The oil pump is started by the start button, thereby delivering the cleaning medium. Gasoline can be used as the cleaning medium here.

[0039] The working principle of this embodiment is as follows:

[0040] Place the valve block 16 on the filter plate 3. Based on the number of ports on the valve block 16, remove the different nozzles 605 from the positioning plate 608. Then insert the nozzle 606 into the port. Open the corresponding first ball valve 607 and start the oil pump 501 to send the cleaning medium to the main pipe 601. From the main pipe 601, the medium enters the housing 602, then through the open connecting pipe 603 to the flexible hose 604, and finally sprays out from the nozzle 606 to clean the ports and the internal piping of the valve block. Unused nozzles 605 remain on the positioning plate 608 for easy storage and to avoid obstructing the rinsing of the valve block.

[0041] Example 2

[0042] Based on Embodiment 1, a conical rubber sleeve 609 is connected to the outer wall of the nozzle 605. The rubber sleeve 609 is installed around the nozzle 605, and the rubber sleeve is conical, meaning the diameter at the upper end is larger than the diameter at the lower end. When the nozzle 605 is inserted into the valve block's inlet, it compresses the rubber sleeve. Because the rubber sleeve is elastic and has a certain degree of damping, it can be tightly secured inside the inlet, preventing the nozzle from falling out under the action of recoil force.
