Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline flushing devices, in particular to a pipeline flushing device for a hydraulic press. Background Art

[0002] Cleaning the hydraulic press pipeline is an important measure to ensure the normal operation of the hydraulic system and extend the service life of the system. The cleanliness of the hydraulic system directly affects the system's reliability and the service life of the components. Before the new equipment is put into operation or after the equipment is overhauled, the system may inevitably be contaminated. These contaminants may come from the installation process of components such as hoses, pipes, and pipe joints, or unexpected contaminants contained in the new oil. If these contaminants are not cleaned in time, they may cause early failures or even cause fatal damage to key components such as pumps and motors.

[0003] Existing hydraulic press pipeline cleaning devices typically include a cleaning pipeline, a fixing device, and a filter. The pipeline to be cleaned is fixed by the fixing device, and then the pipeline to be cleaned is connected to the cleaning pipeline. A degreasing agent, an acidic solution, and an alkaline solution are used to remove dirt in sequence, and then clean water is used to flush. This process usually takes 48 to 60 hours. The cleaning liquid circulates in the cleaning pipeline and the pipeline to be cleaned, and the separated dirt is intercepted by the filter.

[0004] Although the existing technology can effectively clean the dirt in the hydraulic press pipeline, the dirt on the filter surface accumulates continuously when the cleaning fluid circulates through the pipeline to be cleaned, making it difficult for workers to replace the filter in time. The dirt accumulated on the filter surface easily blocks the flow of the cleaning fluid, thereby reducing the flow rate of the cleaning fluid, resulting in a decrease in cleaning efficiency and affecting the cleaning effect.

[0005] Therefore, a hydraulic press pipeline flushing device is proposed to address the above problems. Utility Model Content

[0006] In order to make up for the shortcomings of the existing technology and solve the problem that when the cleaning fluid circulates to flush the pipeline to be cleaned, the dirt on the surface of the filter screen continues to accumulate, making it difficult for the staff to replace the filter screen in time, which easily causes the dirt accumulated on the surface of the filter screen to hinder the flow of the cleaning fluid, thereby causing the flow rate of the cleaning fluid to decrease, resulting in a decrease in cleaning efficiency and affecting the cleaning effect, a hydraulic press pipeline flushing device is proposed.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: a hydraulic press pipeline flushing device described in the present invention comprises a cleaning box body, a control device is installed on one side of the cleaning box body, a water outlet and a water inlet are fixedly installed on the other side of the cleaning box body, the water outlet is fixedly installed above the water inlet, a filter is fixedly installed on one end of the water inlet away from the cleaning box body, a fixing device is installed between the water outlet and the water inlet, the fixing device is fixedly installed on one side of the cleaning box body, and a speed measuring component is provided on the outer wall of the water inlet;

[0008] The speed measuring component includes an isolation shell arranged on the outer wall of the water inlet, a rotating block is rotatably installed on the inner wall of the isolation shell, rotating round rods are fixedly installed on both sides of the rotating block, and vibration components are provided on the outer walls of the rotating round rods. One end of the rotating round rods passes through the isolation shell and extends to both sides of the isolation shell. A speed sensor is installed at one end of the rotating round rods extending to one side of the isolation shell, and the end of the speed sensor away from the rotating round rod is electrically connected to the control device; when the speed of the rotating round rod is lower than a predetermined threshold, the speed sensor sends a signal to the control device, so that the control device sends a signal to notify the staff to check the cleaning condition of the pipeline to be cleaned and replace the filter.

[0009] Preferably, the vibration assembly includes a deflection wheel arranged on the outer wall of the rotating circular rod, one side of the deflection wheel is abutted with an abutment plate, and a driving circular rod is fixedly installed on the side of the abutment plate away from the deflection wheel, and the driving circular rod is slidably installed on the inner wall of the fixing frame, and the fixing frame is fixedly installed on one side of the cleaning box body, and the abutment plate and the fixing frame are connected by a spring, and a vibration mounting plate is fixedly installed on one end of the driving circular rod passing through the fixing frame, and one side of the vibration mounting plate can select an appropriate non-metallic impact head according to the actual material of the cleaning pipe; so that the impact head continuously impacts the pipe to be cleaned, thereby promoting the separation of dirt on the inner wall of the pipe.

[0010] Preferably, the speed measuring component is installed between the cleaning box body and the filter screen, which enables the filtered cleaning liquid to enter the speed measuring component, thereby preventing the cleaning liquid from carrying separated dirt into the speed measuring component.

[0011] Preferably, the maximum distance from the side wall of the deflection wheel to the axis is smaller than the distance between the two ends of the driving rod; this can prevent the abutment plate from abutting against the fixing frame, thereby avoiding movement interference.

[0012] Preferably, the fixing device is provided with a sliding plate and a fixing hole at one end close to the cleaning box body; when the pipeline is longer or shorter, the position of the fixing device away from one end of the cleaning box body can be adjusted through the sliding plate and the fixing hole, so that the pipeline to be cleaned is moved to a suitable position.

[0013] Preferably, two vibration components are provided, and the vibration components are symmetrically installed on both sides of the speed measuring component; this can make the vibration of the pipeline to be cleaned more uniform, improve the separation effect of dirt on the inner wall of the pipeline, and thus improve the cleaning effect of the pipeline.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Specific examples are given below.

[0025] See also Figure 1 one Figure 3 The utility model provides a hydraulic press pipeline flushing device, comprising a cleaning box body 1, a control device 2 is installed on one side of the cleaning box body 1, a water outlet 3 and a water inlet 4 are fixedly installed on the other side of the cleaning box body 1, the water outlet 3 is fixedly installed above the water inlet 4, a filter screen 5 is fixedly installed on one end of the water inlet 4 away from the cleaning box body 1, a fixing device 6 is installed between the water outlet 3 and the water inlet 4, the fixing device 6 is fixedly installed on one side of the cleaning box body 1, and a speed measuring component is provided on the outer wall of the water inlet 4;

[0026] The speed measuring component includes an isolation shell 7 arranged on the outer wall of the water inlet 4, a rotating block 8 is rotatably installed on the inner wall of the isolation shell 7, a rotating round rod 9 is fixedly installed on both sides of the rotating block 8, and a vibration component is provided on the outer wall of the rotating round rod 9. One end of the rotating round rod 9 passes through the isolation shell 7 and extends to both sides of the isolation shell 7. One end of the rotating round rod 9 extending to one side of the isolation shell 7 is equipped with a speed sensor 10, and the end of the speed sensor 10 away from the rotating round rod 9 is electrically connected to the control device 2; through the speed measuring component, when the pipeline of the hydraulic press is cleaned, the cleaning fluid drives the rotating block 8 to rotate, and the rotating block 8 drives the rotating round rod 9 to rotate. The rod 9 rotates, causing the speed sensor 10 to detect the rotation speed of the rotating rod 9. When the rotation speed of the rotating rod 9 is lower than the predetermined threshold, the speed sensor 10 sends a signal to the control device 2, causing the control device 2 to send a signal to notify the staff to check the cleaning condition of the pipeline to be cleaned and replace the filter 5, thereby avoiding the problem that when the cleaning liquid circulates to flush the pipeline to be cleaned, the dirt on the surface of the filter 5 continues to accumulate, and the staff finds it difficult to replace the filter 5 in time, which easily causes the dirt accumulated on the surface of the filter 5 to hinder the flow of the cleaning liquid, thereby causing the flow rate of the cleaning liquid to decrease, resulting in a decrease in cleaning efficiency and affecting the cleaning effect, thereby improving the cleaning efficiency and cleaning effect.

[0027] Further, such as Figure 1 one Figure 3 As shown, the vibration assembly includes a deflection wheel 11 arranged on the outer wall of the rotating round rod 9, and one side of the deflection wheel 11 is abutted with an abutment plate 12, and the side of the abutment plate 12 away from the deflection wheel 11 is fixedly installed with a driving round rod 13, and the driving round rod 13 is slidably mounted on the inner wall of the fixing frame 14, and the fixing frame 14 is fixedly mounted on one side of the cleaning box body 1, and the abutment plate 12 and the fixing frame 14 are connected by a spring 15. The end of the driving round rod 13 passing through the fixing frame 14 is fixedly installed with a vibration mounting plate 16, and one side of the vibration mounting plate 16 can select an appropriate non-metallic impact head according to the actual material of the cleaning pipe; A vibration component is set up. When cleaning the pipeline of the hydraulic press, the rotating rod 9 drives the deflection wheel 11 to rotate, so that the deflection wheel 11 drives the impact head to do reciprocating motion through the abutment plate 12, the driving rod 13, the fixing frame 14 and the spring 15, so that the impact head continuously hits the pipeline to be cleaned, promotes the separation of dirt on the inner wall of the pipeline, avoids the problem that the hard scale and other attachments on the inner wall of the pipeline to be cleaned are difficult to be separated by the cleaning liquid, and thus remain on the pipeline of the hydraulic press, resulting in a decrease in the cleaning effect, improves the cleaning effect, and compared with the traditional manual knocking cleaning process, can also reduce the labor intensity of the operator and improve the cleaning efficiency.

[0028] To sum up, by cooperating with the speed measuring component and the vibration component, the vibration frequency of the vibration component of the pipe to be cleaned can be automatically adjusted according to the actual water flow rate, avoiding the problem that when the vibration frequency is too fast, the dirt is easily broken into fine particles, thereby affecting the speed measuring component through the filter 5. When the vibration frequency is too slow, it is easy to cause insufficient impact force, making it difficult to effectively break the adhesion between the dirt and the pipe, resulting in dirt remaining on the inner wall of the pipe, affecting the cleaning effect of the device on the pipe, thereby improving the accuracy and effectiveness of the device, thereby improving the cleaning effect of the device.

[0029] Further, such as Figure 1 one Figure 3 As shown, the speed measuring component is installed between the cleaning box body 1 and the filter 5; it can allow the filtered cleaning liquid to enter the speed measuring component, avoiding the cleaning liquid carrying separated dirt into the speed measuring component, which easily causes the dirt to adhere to the outer wall of the rotating block 8 and the rotating rod 9, causing motion interference to the rotation of the rotating block 8 and the rotating rod 9, thereby causing the speed information collected by the speed sensor 10 to be less accurate, resulting in a decrease in the working effect of the speed measuring component, and improving the stability and reliability of the speed measuring component.

[0030] Further, such as Figure 2 one Figure 3 As shown, the maximum distance from the side wall of the deflection wheel 11 to the axis is smaller than the distance between the two ends of the driving rod 13; this can prevent the abutment plate 12 from abutting against the fixing frame 14, thereby avoiding the problem that when the distance between the two ends of the driving rod 13 is short, the abutment plate 12 easily abuts against one side of the spring 15 during the rotation of the deflection wheel 11, so that the abutment plate 12 hinders the rotation of the deflection wheel 11 and causes motion interference, thereby improving the stability and reliability of the device.

[0031] Further, such as Figure 1 one Figure 2 As shown, a sliding plate and a fixing hole are provided at one end of the fixing device 6 close to the cleaning box body 1; when the pipeline is longer or shorter, the position of the fixing device 6 away from one end of the cleaning box body 1 can be adjusted through the sliding plate and the fixing hole, so that the pipeline to be cleaned is moved to a suitable position, avoiding the problem that when the pipeline to be cleaned is longer or shorter, the distance between the two ends of the pipeline and the water outlet 3 and the water inlet 4 is too close or too far, causing difficulty in connection, thereby improving the applicability of the device.

[0032] Further, such as Figure 1 one Figure 3As shown, there are two vibration assemblies, which are symmetrically installed on both sides of the speed measuring assembly; this can make the force on both sides of the rotating block 8 uniform, reduce the bending moment of the rotating rod 9, and extend the service life of the rotating rod 9. By symmetrically installing the vibration assemblies, the vibration of the pipeline to be cleaned is made more uniform, which improves the separation effect of dirt on the inner wall of the pipeline, thereby improving the cleaning effect of the pipeline.

[0033] Working principle: When the hydraulic press pipeline needs to be cleaned, the pipeline to be cleaned is placed on one end of the fixing device 6, and the pipeline to be cleaned is clamped and fixed by the fixing device 6. At this time, the position of the pipeline to be cleaned can be adjusted by the sliding plate and the fixing hole provided at one end of the fixing device 6, so that the connection between the pipeline to be cleaned and the water outlet 3 and the water inlet 4 is more convenient. At this time, the two ends of the pipeline to be cleaned are connected to the water outlet 3 and the water inlet 4;

[0034] After the pipeline to be cleaned is installed, the control device 2 is operated to start the cleaning box body 1, so that the cleaning liquid flows into the pipeline to be cleaned through the water outlet 3, flushes the inner wall of the pipeline to be cleaned, and then flows into the cleaning box body 1 through the water inlet 4. At the same time, the filter screen 5 provided at one end of the water inlet 4 can block the dirt carried by the cleaning liquid. After the cleaning liquid passes through the filter screen 5, it pushes the rotating block 8, so that the rotating block 8 drives the rotating rod 9 to rotate, so that the speed sensor 10 detects the rotation rate of the rotating rod 9. At this time, the rotating rod 9 drives the deflection wheel 11 to rotate, so that the deflection wheel 11 pushes the abutment plate 12 to move, and the abutment plate 12 drives the driving rod 13 to move. At this time, the abutment plate 12 squeezes the spring 15. The spring 15 is elastically deformed, accumulating elastic potential energy, and at the same time driving the round rod 13 to drive the vibration mounting plate 16 to move, and the vibration mounting plate 16 drives the impact head to hit the pipeline to be cleaned, and the deflection wheel 11 continues to rotate, so that the protruding outer wall of the deflection wheel 11 stops abutting against one side of the abutment plate 12. At this time, the spring 15 releases its elastic potential energy and elastically deforms to push the spring 15 to move in the direction close to the deflection wheel 11, and the abutment plate 12 drives the driving round rod 13 to move, and the driving round rod 13 drives the vibration mounting plate 16 to move, and the vibration mounting plate 16 drives the impact head to move, so that the impact head continuously hits the pipeline to be cleaned, causing the pipeline to vibrate, thereby promoting the separation of dirt on the inner wall of the pipeline;

[0035] When there is a lot of dirt attached to the surface of the filter 5, the dirt hinders the circulation of the cleaning liquid, causing the flow rate of the cleaning liquid to decrease. At this time, the speed sensor 10 detects the speed of the rotating rod 9. When the speed of the rotating block 8 is lower than the preset threshold, the speed sensor 10 sends a signal to the control device 2, so that the control device 2 sends a signal to notify the staff to check the cleaning condition of the pipeline to be cleaned and replace the filter 5, avoiding untimely replacement of the filter 5, thereby improving the cleaning effect of the pipeline.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
