Description

Technical Field

[0001] The utility model designs a filter, specifically relating to a filter for a hydraulic support. Background Art

[0002] A filter screen of a filter for a hydraulic support. The filter for a hydraulic support is widely used in mine exploitation and construction machinery to filter impurities in hydraulic oil and ensure the normal operation of the hydraulic system. Traditional filters are often blocked due to the accumulation of impurities and require frequent maintenance, which affects work efficiency.

[0003] Traditional equipment lacks a locking mechanism and has poor stability and reliability in a high-pressure environment. Traditional equipment relies on a simple mechanical support, which is difficult to provide sufficient supporting force and is prone to deformation or damage in a high-pressure working environment, affecting the normal operation of the hydraulic system. The stability of the hydraulic support is directly related to the working efficiency and service life of the filter. Equipment lacking a stable support design is prone to failures under high-pressure or high-load conditions. In addition, the traditional support design is not equipped with an effective locking mechanism. During the operation of the filter, the support may shift or loosen, increasing the risk of equipment failure and the complexity of maintenance. Due to these deficiencies in the design of traditional hydraulic support filters, users need to frequently check and maintain the equipment to ensure that the filter does not undergo accidental displacement or damage during operation. This not only increases the maintenance cost and workload of the equipment but also may lead to an extended downtime of the equipment, affecting production efficiency.

[0004] Traditional equipment is prone to blockage due to the accumulation of impurities during use, affecting the filtering effect and the normal operation of the hydraulic system. Traditional equipment relies on manual cleaning and maintenance, which is complex and time-consuming. When the filter screen is blocked by impurities, the filtering effect significantly decreases, reducing the cleanliness of the hydraulic oil and also causing increased wear of the components in the hydraulic system, shortening the service life of the equipment. In addition, the frequency and effect of manual cleaning are not easy to control, resulting in problems such as incomplete cleaning or overly frequent cleaning, increasing the maintenance cost and workload. Traditional hydraulic support filters are particularly prone to blockage problems in a highly polluted environment, affecting the continuous and stable operation of the equipment. In working conditions such as mine exploitation and construction machinery with harsh environments, the accumulation rate of impurities and particulate matter is relatively fast. The filter needs to be frequently cleaned and replaced, increasing the operation difficulty and workload, and also causing equipment damage or hydraulic system failures due to untimely cleaning.

[0005] During the use of traditional equipment, real-time monitoring and automatic control cannot be achieved, which increases the difficulty of operation and maintenance. Traditional equipment mainly relies on regular manual inspections and maintenance, and it is impossible to detect and handle blockages or failures of filters in a timely manner. When the filter becomes blocked, it is difficult for the operator to notice in time, resulting in failures or damages to the hydraulic system due to poor filtration, affecting production efficiency and the service life of the equipment. During the working process, real-time filtration status information and early warnings cannot be provided, increasing the uncertainty and risks of operation. Traditional equipment relies on manual data recording and analysis, making it difficult to achieve efficient data management and fault diagnosis. Operators need to spend a lot of time and energy on monitoring and analyzing the equipment status, increasing the work burden and the risk of errors. In a high-intensity working environment, it is difficult to ensure the frequency and accuracy of manual inspections and maintenance, resulting in a decline in the operating efficiency and reliability of the equipment. Summary of the Invention

[0006] The purpose of the present utility model is to provide a hydraulic support filter, which solves the problems that the support of the traditional filter is unstable, shortening the equipment life, and it cannot be self-cleaned, affecting the cleaning effect.

[0007] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0008] A hydraulic support filter includes a main body, a locking member, and a hydraulic cylinder. The top end of the main body is connected to the locking member, and the bottom end is connected to the telescopic rod of the hydraulic cylinder; a filter hole group is provided on the main body, and the filter hole group includes several filter holes; a cavity is provided inside the main body, and a flow sensor, a cleaning nozzle, a pressure sensor, and a data processor are installed in the cavity. The flow sensor is adapted to the filter hole group. The cleaning nozzle is located at the bottom end of the main body, the pressure sensor is located outside the cleaning nozzle, and the cleaning nozzle is electrically connected to the data processor.

[0009] Further, the filter holes are evenly distributed along the axial direction of the main body. Fourteen filter hole layers are formed by multiple filter holes from top to bottom. The filter holes are rectangular, and chamfers are respectively provided on the outside of each filter hole.

[0010] Further, a flow sensor is provided between two adjacent filter hole layers.

[0011] Further, an anti-flushing valve is installed at the bottom end of the main body, and the anti-flushing valve is electrically connected to the data processor.

[0012] Further, the fixed end of the hydraulic cylinder has a fixed disk, and the fixed disk is connected to the fixed flange through bolts.

[0013] Further, the bottom end of the main body has a buckle, and the hydraulic cylinder is fixedly connected to the main body through the buckle.

[0014] Further, there are four cleaning nozzles in total. The cleaning nozzles are fixed in the main body through a turntable; the cleaning nozzles are evenly distributed on the turntable along the axial direction.

[0015] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0016] By adding a locking member at the top end of the main body and a hydraulic cylinder at the bottom end of the main body, the stability and reliability of the device are enhanced. The hydraulic cylinder can provide strong and stable supporting force, and through the action of hydraulic oil, it pushes and supports the filter, ensuring that it does not deform or damage under high-pressure working conditions, thereby guaranteeing the normal operation of the hydraulic system. The locking member can effectively fix the position of the bracket during the operation of the filter, prevent displacement or loosening, and reduce the risk of equipment failure. This device can significantly reduce the maintenance frequency, extend the service life of the equipment, and improve production efficiency. Especially in high-intensity working environments such as mining and construction machinery, the application of the hydraulic cylinder and the locking member enables the equipment to maintain stable operation under high-pressure and high-load conditions, reduce unexpected downtime, and ensure the continuity and stability of the production process.

[0017] By adding a backwash valve and cleaning nozzles, the filter of the utility model has a self-cleaning function, which solves the blockage problem caused by impurity accumulation during the use of traditional equipment. The backwash valve can automatically start the reverse flushing process when the filter screen is blocked by controlling the opening and closing of the valve, removing the impurities attached to the filter screen and maintaining the filtering effect. The cleaning nozzles are arranged around the filter screen. When the reverse flushing process is started, high-pressure liquid is sprayed to thoroughly clean the surface of the filter screen, effectively removing the accumulated impurities and particles. The realization of the self-cleaning function improves the maintenance efficiency of the filter, reduces the frequency and workload of manual cleaning, and reduces the maintenance cost. The automatic backwash process ensures that the filter is always in the best working state, improves the cleanliness of the hydraulic oil, reduces the wear of the components of the hydraulic system, and extends the service life of the equipment. In high-pollution environments such as mining and construction machinery, the self-cleaning function is particularly important, which can significantly improve the continuous and stable operation ability of the equipment, reduce equipment damage or hydraulic system failures caused by untimely cleaning, and ensure the smooth progress of the production process.

[0018] The utility model can realize real-time monitoring and automatic control of the hydraulic support filter by adding a pressure sensor, a flow sensor and a data processor, improving the operation and maintenance efficiency of the equipment. The pressure sensor is located between two adjacent filter hole layers, monitoring the pressure difference inside and outside the filter in real time. When the pressure difference exceeds the set value, it triggers an alarm or starts the self-cleaning function to ensure the normal operation of the filter. The flow sensor monitors the liquid flow through the filter, detects abnormal flow conditions, judges whether the filter screen is blocked, and provides data support. The data processor collects and analyzes the data from the pressure sensor and the flow sensor, controls the self-cleaning process and provides real-time monitoring information. The data processor is electrically connected to the central control room. Technicians can observe the display screen and the alarm system in the central control room, enabling operators to grasp the working state of the filter in real time and take timely measures in case of failures, reducing the equipment downtime and maintenance costs. This allows the hydraulic support filter to operate efficiently and stably in a high-intensity working environment, reducing the frequency of manual inspections and maintenance, improving the efficiency of data management and fault diagnosis, reducing the risk of operation errors, and significantly enhancing the operation efficiency and reliability of the equipment.

[0020] Figure 2 It is a sectional view of a hydraulic support filter. Detailed Embodiment

[0021] Such as Figure 1 And Figure 2As shown in the figure, a hydraulic support filter includes a main body 1, a locking member 2, and a hydraulic cylinder 3. The top end of the main body 1 is connected to the locking member 2, and the bottom end is connected to the telescopic rod of the hydraulic cylinder 3. The main body 1 is provided with a filter hole group, and the filter hole group includes a number of filter holes 4. A cavity is provided inside the main body 1, and a flow sensor 6, a cleaning nozzle 7, a pressure sensor 8, and a data processor 9 are installed in the cavity. The flow sensor 6 is adapted to the filter hole 4 group. The cleaning nozzle 7 is located at the bottom end of the main body 1, and the pressure sensor 8 is located outside the cleaning nozzle 7. The cleaning nozzle 7 is electrically connected to the data processor 9. The fixed end of the hydraulic cylinder 3 has a fixed disk, and the fixed disk is connected to the fixed flange through bolts. The pressure sensor 8 is used to monitor the pressure difference inside and outside the filter. When the pressure difference exceeds the set value, it triggers an alarm or activates the self-cleaning function. The pressure sensor 8 needs to have high precision and high response speed, and be able to monitor and feedback the pressure change in real time. The material and structure of the sensor can withstand high-pressure and high-temperature environments, avoiding damage or failure due to harsh working conditions, and ensuring the safe operation of the equipment. The data processor 9 is used to collect and analyze the data from the pressure sensor 8 and the flow sensor 6. The data processor 9 has powerful computing power and data storage capacity, can process a large amount of sensor data in real time, and control the self-cleaning process according to the preset algorithms and logics. The interface design of the data processor 9 is compatible with various sensors and display devices, ensuring the integration and scalability of the system.

[0022] The main body 1 is made of high-strength metal material, which can ensure the durability and stability of the main body 1 in a high-pressure environment. The locking member 2 is the key to ensuring the stability of the main body 1 during operation. The locking member 2 can be a mechanical lock or a hydraulic lock to achieve the locking purpose. The mechanical lock uses a bolt structure, and the hydraulic locking structure uses a hydraulic pushing device to fix the main body 1 in a predetermined position. The locking member 2 can ensure that the main body 1 will not loosen in a high-pressure and high-vibration environment, prevent the filter from shifting or falling off during operation, and ensure the safe operation of the equipment. The hydraulic cylinder 3 can provide a supporting force for the main body 1. By the pressure of the hydraulic oil, it pushes the telescopic rod to generate a strong supporting force to fix the main body 1. The hydraulic cylinder 3 uses high-strength alloy materials and high-quality seals to prevent hydraulic oil leakage and internal component wear. The filter holes 4 are used to intercept impurities in the liquid. The size and density of the filter holes 4 determine the filtration accuracy of the filter. It is made of stainless steel wire mesh or other corrosion-resistant materials, and uniform pore diameters are formed through precision weaving or punching processes. The filter holes 4 need to have high strength and wear resistance to ensure that they will not deform or be damaged during long-term use, and maintain a stable filtration effect.

[0023] The filter holes 4 are evenly distributed along the axial direction of the main body. A total of fourteen filter hole layers are formed by multiple filter holes 4 from top to bottom. The filter holes 4 are rectangular, and chamfers are respectively provided on the outside of each filter hole 4. A flow sensor 6 is provided between two adjacent filter hole layers. The flow sensor 6 is used to monitor the liquid flow rate through the filter, helping to judge the working state of the filter. The flow sensor 6 adopts electromagnetic or ultrasonic technology, and obtains data by measuring the speed and flow rate of the liquid flowing through the sensor. The flow sensor 6 has high precision and durability, and can work stably in high-pressure and high-temperature environments. The data transmission interface of the flow sensor 6 is compatible with the data processor 9 to ensure the real-time transmission and analysis of data.

[0024] A backwash valve 10 is installed at the bottom end of the main body 1. The backwash valve 10 is electrically connected to the data processor 9. The backwash valve 10 is the core component for realizing the self-cleaning function. By controlling the opening and closing of the valve, the filter holes 4 are backwashed to remove the attached impurities. The backwash valve 10 has high-pressure tolerance and good sealing performance, and is made of high-strength metal materials and high-quality seals. The control system of the valve is linked with the data processor 9, and automatically adjusts the opening and closing time of the valve according to the data fed back by the sensor to ensure the efficiency and reliability of the self-cleaning process.

[0025] The bottom end of the main body 1 is provided with a buckle 5. The hydraulic cylinder 3 is fixedly connected to the main body 1 through the buckle 5. The buckle 5 is used to fix and connect the various components of the filter to ensure that they will not loosen or fall off under high-pressure and high-vibration environments. The design of the buckle 5 needs to have sufficient strength and reliability, is made of high-strength metal materials, and undergoes precision machining and surface treatment. The structure of the buckle 5 should be convenient for installation and disassembly to facilitate the maintenance and replacement of components of the filter and improve work efficiency.

[0026] There are a total of four cleaning nozzles 7. The cleaning nozzles 7 are fixed in the main body 1 through a turntable; the cleaning nozzles 7 are evenly distributed along the axial direction on the turntable. The cleaning nozzles 7 are key components of the self-cleaning function. They are installed at the bottom end of the main body 1 and are used to spray high-pressure liquid to remove the impurities attached to the filter mesh. The fixing angles of the four nozzles are different, and the four nozzles can effectively cover and clean the entire set of filter holes 4. The cleaning nozzles 7 are made of high-pressure and corrosion-resistant materials and can be used for a long time without damage under the impact of high-pressure liquid.

[0027] The utility model improves the stability and reliability of the equipment in a high-pressure environment by installing a hydraulic cylinder 3 and a locking member 2 on the main body 1. The hydraulic cylinder 3 is designed with alloy materials and equipped with high-quality seals to ensure no leakage under high pressure. The hydraulic cylinder 3 pushes the piston rod through hydraulic oil to provide strong supporting force, enabling the filter to maintain stability under high-load conditions. The telescopic rod of the hydraulic cylinder 3 is connected to the main body 1, and the firmness and sealing performance of the connection are ensured through precise machining of the connection part. The locking member 2 adopts a mechanical lock or hydraulic locking method. The mechanical lock includes a bolt structure that can quickly fix the bracket. Hydraulic locking pushes the locking device through hydraulic oil to fix the main body 1 in a predetermined position. The design of the locking mechanism ensures that it will not loosen under high pressure and high-vibration environments, guaranteeing the stability of the equipment during operation. Through this design, the hydraulic support filter can significantly reduce the risk of displacement and loosening of the equipment in a high-pressure environment, reduce the need for frequent maintenance and inspection, thereby reducing maintenance costs and improving production efficiency, and is particularly suitable for high-intensity working environments such as mine exploitation and construction machinery.

[0028] By introducing a backwash valve 10 and a cleaning nozzle 7 at the bottom end of the main body 1, a self-cleaning function is achieved, solving the blockage problem caused by impurity accumulation in traditional equipment. The backwash valve 10 is designed with high-strength metal materials and high-quality seals to ensure its durability and sealing performance under high-pressure environments. The backwash valve 10 is electrically connected to the data processor 9 and can automatically control the opening and closing of the valve according to the pressure difference or flow rate change inside and outside the filter. When it is detected that the filter holes 4 are blocked, the backwash valve 10 automatically starts the reverse flushing process, and impurities attached to the filter holes 4 are removed through reverse flow of the valve. The cleaning nozzle 7 is arranged at the bottom end of the main body 1 and is made of high-pressure and corrosion-resistant materials to ensure its long-term use under the impact of high-pressure liquid. When the backwash process is started, the cleaning nozzle 7 sprays high-pressure liquid to thoroughly clean the surface of the filter screen, effectively removing accumulated impurities and particles. Through this self-cleaning design, the filter can maintain the best working state, improve the cleanliness of the hydraulic oil, reduce the wear of hydraulic system components, and extend the service life of the equipment. This technical design is particularly important in highly polluted environments such as mine exploitation and construction machinery, which can significantly improve the continuous and stable operation ability of the equipment, reduce equipment damage or hydraulic system failures caused by untimely cleaning, and ensure the smooth progress of the production process.

[0029] The hydraulic support filter realizes real-time monitoring and automatic control of the equipment by introducing a pressure sensor 8, a flow sensor 6 and a data processor 9, improving the operation and maintenance efficiency. The pressure sensor 8 is installed at the bottom end of the main body 1 and adopts high-precision sensing technology to monitor the pressure difference inside and outside the filter in real time. The sensor transmits data to the data processor 9 through a data cable or wirelessly. When the pressure difference exceeds the set value, the data processor 9 automatically triggers the alarm system to remind the operator to perform maintenance or start the self-cleaning function. The flow sensor 6 is installed between adjacent filter hole layers to monitor the change in liquid flow rate. The flow sensor 6 adopts electromagnetic or ultrasonic technology to ensure high precision and high reliability. The data processor 9 can collect and analyze the data from the pressure sensor 8 and the flow sensor 6 in real time and control the self-cleaning process according to the preset algorithms and logic. The data processor 9 is electrically connected to the central control room. Through observing the display screen and the alarm system in the central control room, the operator can grasp the working state of the filter in real time. The operator can timely understand the equipment state through this information and quickly take measures in case of a failure. The application of the intelligent monitoring system enables the hydraulic support filter to operate efficiently and stably in a high-intensity working environment, reducing the frequency of manual inspections and maintenance, improving the efficiency of data management and fault diagnosis, reducing the risk of operation errors, and significantly enhancing the operation efficiency and reliability of the equipment.
