Description

Technical Field

[0001] The utility model relates to the technical field of filter press separation equipment, in particular to a telescopic liquid receiving mechanism for a filter press. Background Art

[0002] As an important solid-liquid separation equipment, filter press plays a key role in many industrial fields. Its working principle is usually to use a pressure pump to pressurize the material to be filtered into a filter chamber composed of multiple filter plates. Under the strong pressure, the liquid in the material seeps through the filter cloth, while the solid particles are trapped on the filter cloth, thus achieving efficient solid-liquid separation.

[0003] However, in the actual operation of the filter press, the filtrate often seeps out from between the filter plates. If the seeping filtrate cannot be collected in time and effectively, it will not only cause serious pollution to the working environment, but also make the site damp and dirty, affecting the operator's work experience and work efficiency. In addition, the chemical substances in the filtrate may corrode the equipment, shorten the service life of the filter press, and increase the maintenance cost and repair frequency of the equipment.

[0004] There are many drawbacks in the traditional filter press liquid receiving device. For example, the traditional liquid receiving device generally adopts a flap structure, which not only takes up a large space, but also increases the overall height of the device. Its use in a working environment with limited space is greatly restricted, and the flap structure is not flexible enough during operation. In addition, the traditional liquid receiving device may also have problems such as complex structure, inconvenient installation and maintenance, which brings many troubles to users.

[0005] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content

[0006] The utility model provides a telescopic liquid receiving mechanism for a filter press, which has a simple structural design, significant liquid receiving effect, small space occupation, convenient installation and maintenance, low cost, and solves the problems existing in the prior art.

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

[0008] A telescopic liquid receiving mechanism for a filter press, comprising:

[0009] The telescopic folding part is a flexible telescopic folding structure which is gradually inclined downward from the middle to both sides, and one end of the telescopic folding part along the telescopic direction is fixed, and the other end is a free end;

[0010] A transmission assembly, wherein the transmission assembly includes a transmission trolley, the transmission trolley is connected to the free end of the telescopic folding part, and the transmission trolley pulls the free end of the telescopic folding part to achieve the extension or compression of a certain area of ​​the flexible telescopic folding structure;

[0011] The fixing assembly is used to support the telescopic folding part and the transmission assembly, and the transmission assembly drives the telescopic folding part to move along the length direction of the fixing assembly.

[0012] Furthermore, the telescopic folding part includes a support plate, a folding part and a roller assembly, and the roller assembly is arranged on the inner side of the bottom end of the support plate; the telescopic folding part is driven by the roller assembly to slide along the fixed assembly.

[0013] Furthermore, a plurality of the support plates are arranged at intervals along the extension direction of the telescopic folding portion, and the folding portion is arranged at the top end of the support plate, and the folding portion is a folding portion made of a flexible sealing and corrosion-resistant material.

[0014] Furthermore, the flexible sealing corrosion-resistant material folding portion is a folding portion made of a rubber and fiber composite material.

[0015] Furthermore, the top surface of the support plate is arranged in a triangular shape, and upwardly concave inverted L-shaped legs are arranged on both sides of the bottom of the support plate, and rollers are arranged on the inner top surface and inner side surface of the inverted L-shaped legs. The four rollers arranged at the bottom of each support plate constitute the roller assembly.

[0016] Furthermore, the transmission assembly includes a driving motor, a transmission shaft, a transmission sprocket, a transmission chain, a driven sprocket, a sensor and a transmission trolley; the driving motor, the transmission shaft and the transmission sprocket are arranged at one end of the fixed assembly, the driven sprocket is arranged at the other end of the fixed assembly, and the transmission chain is arranged between the driving sprocket and the driven sprocket; the transmission trolley is driven by the transmission chain to move along the length direction of the fixed assembly, the transmission trolley is fixedly connected to the free end of the telescopic folding part, and the sensor is arranged on the fixed assembly below the transmission trolley.

[0017] Furthermore, the driving motor is a reduction motor.

[0018] Furthermore, the transmission assembly also includes an adjusting assembly, which is arranged on the fixed assembly close to the driven sprocket and is mainly used to adjust the chain tension.

[0019] Furthermore, the fixing assembly includes a frame, a main beam and a guide rail. The main beams are symmetrically arranged on both sides of the frame, and the guide rails are arranged on the outer sides of each main beam via a support frame.

[0020] Furthermore, the guide rail comprises an upper guide rail and a lower guide rail, and the transmission trolley and the telescopic folding part are both arranged on the upper guide rail.

[0021] Further, the sensor includes a position sensor and / or a speed sensor.

[0022] Furthermore, the reduction motor support is fixed to the middle of one end of the frame, the two ends of the transmission shaft are respectively passed through the main beams on both sides of the same end of the frame, a transmission sprocket is set on the transmission shaft outside each main beam, and the transmission chain between the transmission sprocket and the driven sprocket is passed through the inside of the guide rail. The bottom of the upper guide rail is open for connecting the transmission trolley.

[0023] Furthermore, the roller assemblies on both sides of the bottom of the telescopic folding portion are slidably matched with the top surface and side surfaces of the upper guide rail.

[0024] Furthermore, the frame includes front legs and rear legs, and the main beam support is fixed on the front and rear legs on the same side.

[0025] Furthermore, the telescopic liquid receiving mechanism for the filter press also includes a controller, which is used to receive signals of the transmission speed, transmission position and position of the flexible telescopic folding part of the transmission component and control the transmission of the transmission component.

[0026] Furthermore, the controller is a PLC controller. The sensor arranged on the fixed component can monitor the position and / or speed of the transmission trolley and feed the data back to the PLC controller to accurately control the transmission.

[0027] Furthermore, at the beginning of the operation of the filter press, the PLC controller starts the reduction motor of the transmission assembly in combination with the preset program, and the reduction motor drives the transmission sprocket to rotate through the transmission shaft, and the transmission sprocket then drives the driven sprocket to rotate through the transmission chain, so that the transmission trolley moves on the guide rail. When the transmission trolley moves along the length direction of the main beam, it will drive the telescopic folding part to extend or contract. During the extension process of the telescopic folding part, its folding part will gradually unfold, expanding the liquid receiving area to ensure that the filtrate seeping from between the filter plates of the filter press can be caught.

[0028] During the operation of the filter press, the sensor monitors the operating status of the transmission component in real time. If the transmission speed is found to be too fast or too slow, the sensor can feed back the data to the control system, which then adjusts the speed of the reduction motor to ensure that the extension speed of the telescopic folding part is moderate, so that the filtrate can be caught in time and will not be damaged due to excessive extension. At the same time, the sensor can also monitor the position of the telescopic folding part to ensure that it is located below the filtrate seepage position to achieve the best liquid connection effect.

[0029] When the filter press stops working or needs maintenance, the control system issues a command to control the reduction motor to reverse. At this time, the transmission trolley moves back and moves toward the direction close to the filter press cylinder, driving the telescopic folding part to shrink. During the shrinking process, the telescopic folding part will gradually reduce the liquid contact area, reduce the occupied space, and facilitate the operator to carry out maintenance and cleaning work.

[0030] The telescopic liquid receiving mechanism is arranged on the frame below the filter press and is used in conjunction with the filter press to achieve effective liquid receiving of filter plate leakage. It has flexible adjustment, occupies less space and is easy to operate.

[0031] Beneficial effects of the utility model:

[0032] 1. The telescopic liquid receiving mechanism of the utility model has a simple structure, mainly consisting of a telescopic folding part, a fixed component and a transmission component, and is easy to manufacture and install. The main beam and guide rails in the fixed component enable the telescopic folding part responsible for receiving the liquid to be stably installed on the filter press frame, and can be easily disassembled and replaced when maintenance is required. The various devices in the transmission component are also easy to maintain and overhaul.

[0033] 2. The telescopic liquid contact mechanism has excellent liquid contact effect. The flexible sealing corrosion-resistant material of the telescopic folding part has good elasticity and sealing, which can ensure the liquid contact area to the greatest extent, effectively prevent the filtrate from leaking out, improve the liquid contact effect, and significantly extend the service life of the liquid contact mechanism.

[0034] 3. Compared with the traditional flap structure, the telescopic liquid receiving mechanism occupies less space and can effectively reduce the overall height of the device. The telescopic folding part does not occupy too much space in the retracted state, making the overall structure of the filter press more compact, which is particularly suitable for working environments with limited space.

[0035] 4. The telescopic liquid contact mechanism is low-cost and easy to replace after damage, which reduces maintenance costs and downtime and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] like Figure 1 - 6, shows the structure of the telescopic liquid receiving mechanism for the filter press. Specifically, the telescopic liquid receiving mechanism includes a transmission assembly 100, a telescopic folding portion 200 and a fixing assembly 300. The telescopic folding portion 200 is arranged to be gradually tilted downward from the middle to both sides, and the folding portion is a flexible telescopic folding structure. The telescopic folding portion is fixed at one end along its telescopic direction, and the other end is a free end. The transmission assembly 100 includes a transmission trolley 150, which is connected to the free end of the telescopic folding portion. The transmission trolley pulls the free end of the telescopic folding portion to achieve the extension or compression of a certain area of ​​the flexible telescopic folding structure. The fixing assembly 310 is used to support the telescopic folding portion and the transmission assembly, and the transmission assembly 100 drives the telescopic folding portion 200 to move along the length direction of the fixing assembly 300.

[0047] The telescopic folding part 200 comprises a support plate 210, a folding part 220 and a roller assembly 230. The roller assembly is arranged on the inner side of both ends of the bottom of the support plate. The telescopic folding part is driven by the roller assembly to slide along the fixed assembly. A plurality of support plates are arranged at intervals along the extension direction of the telescopic folding part. The top surface of the support plate is arranged in a triangular shape. An upwardly concave inverted L-shaped leg is arranged at both ends of the bottom of the support plate. Rollers are arranged on the inner top surface and inner side surface of the inverted L-shaped leg. The four rollers arranged at the bottom of each support plate constitute the roller assembly 230. The folding part 220 is arranged between adjacent support plates. The folding part is made of a flexible sealing and corrosion-resistant material.

[0048] The transmission assembly 100 includes a reduction motor 110, a transmission shaft 120, a transmission sprocket 130, a transmission chain 140, a transmission trolley 150, a sensor 160, an adjustment assembly 170 and a driven sprocket 180; the reduction motor, the transmission shaft and the transmission sprocket are arranged at one end of the length direction of the fixed assembly, the driven sprocket is arranged at the other end of the fixed assembly, and the transmission chain is arranged between the transmission sprocket and the driven sprocket; the transmission trolley is driven by the transmission chain to move along the length direction of the fixed assembly, the transmission trolley is fixedly connected to the free end of the telescopic folding part, and the sensor 160 can be arranged on the fixed assembly below the transmission trolley.

[0049] Specifically, the fixing assembly 300 includes a frame, a main beam 310 and a guide rail 320. The main beams are symmetrically arranged on both sides of the frame, and the guide rail 320 is arranged on the outer side of each main beam via a support frame 330. The guide rail includes two guide rails spaced apart at an upper and a lower position, and the transmission trolley 150 and the telescopic folding part 200 are both arranged on the guide rail at the upper outer side of the main beam. The roller assemblies 230 on both sides of the bottom of the telescopic folding part slide with the top and side surfaces of the guide rail at the upper outer side of the main beam. The sensor can be a position sensor and / or a speed sensor, and its appropriate installation position on the guide rail is determined in combination with its requirements for the position or speed monitoring function.

[0050] The reduction motor 110 is supported and fixed in the middle of one end of the frame, and both ends of the transmission shaft pass through the main beams on both sides of the same end of the frame respectively. A transmission sprocket is set on the transmission shaft outside each main beam, and the transmission chain between the transmission sprocket and the driven sprocket is passed through the inside of the guide rail 320.

[0051] The aforementioned frame includes a frame front support leg 410 and a frame rear support leg 420, and the main beam support is fixed on the frame front and rear support legs on the same side.

[0052] Furthermore, the telescopic liquid receiving mechanism for the filter press also relates to a control system, which includes a controller for determining and controlling the transmission speed, transmission position and position of the flexible telescopic folding portion of the transmission trolley.

[0053] Furthermore, the controller may be a PLC controller. The sensor 160 provided on the guide rail can monitor the position and speed of the transmission trolley 150 and feed the data back to the PLC controller to accurately control the transmission.

[0054] In actual use, the installation and debugging process of the above structural components of the telescopic liquid contact mechanism is as follows:

[0055] 1. Component Installation

[0056] 1. Fixed component installation

[0057] The front support legs 410 and the rear support legs 420 of the frame are installed at appropriate positions of the filter press to ensure that they are stable and firm, and provide basic support for the entire liquid receiving mechanism.

[0058] The main beam 310 is installed on the front legs 410 and the rear legs 420 of the frame, and a high-strength connection method is adopted, such as welding or strong bolt connection, to ensure that the main beam 310 can withstand the weight of the liquid receiving mechanism and various forces generated when the filter press is working, such as vibration and pressure.

[0059] The guide rail 320 is installed on the main beam 310 to ensure the installation accuracy of the guide rail 320 so that its horizontality and straightness meet the design requirements. The guide rail 320 is used to provide a stable running track for the transmission trolley 150. When installing, it is necessary to ensure that it is tightly connected to the main beam 310 without looseness.

[0060] The guide rail 320 is connected and fixed to the main beam 310 using the support frame 330, and the installation position of the support frame 330 should be reasonably distributed to ensure the stability of the guide rail 320. During installation, it is necessary to ensure that the connection between the support frame 330, the guide rail 320 and the main beam 310 is firm and reliable, and can withstand various forces during operation to prevent the guide rail 320 from deformation or shaking during operation.

[0061] 2. Transmission component installation

[0062] The reduction motor 110 is installed at one end of the main beam 310 or at a suitable position, and the vibration generated when the motor is running is reduced by devices such as shock-absorbing pads to reduce the impact on the entire mechanism, and ensure that it is firmly installed.

[0063] The transmission shaft 120 is used to connect the reduction motor 110 and the transmission sprocket 130. The transmission shaft 120 must be installed to ensure that it is concentric with the motor shaft and the transmission sprocket 130 to ensure the stability and efficiency of power transmission. When installing, use a suitable coupling or key connection method to ensure reliable connection.

[0064] The transmission trolley 150 is installed on the guide rail 320, and a sliding or rolling method with a low friction coefficient should be adopted between the transmission trolley 150 and the guide rail 320, such as installing rollers or using a smooth and wear-resistant slider, so as to ensure that the transmission trolley 150 can move smoothly on the guide rail 320. At the same time, the structural strength and stability of the transmission trolley 150 must be ensured to be able to withstand the weight of the telescopic folding part 200 and various forces during operation.

[0065] The sensor 160 is installed on the guide rail 320. The installation position of the sensor 160 is determined according to its monitoring function. For example, a sensor for monitoring the transmission speed can be installed near the transmission sprocket 130, and a sensor for monitoring the position can be installed at the connection between the transmission trolley 150 and the telescopic folding part 200. The sensor 160 should be installed firmly and ensure that it can accurately collect relevant data and accurately transmit the data to the control system.

[0066] The driven sprocket assembly is installed at the other end of the guide rail 320. The driven sprocket assembly must be installed on the same horizontal plane as the drive sprocket 130, and the drive chain 140 can be properly tensioned, neither too loose to cause the chain to fall off or slip, nor too tight to increase the motor load and component wear.

[0067] The transmission chain 140 runs in the guide rail 320. During installation, attention should be paid to the direction and tension adjustment of the chain. The chain tension can be achieved by using a special tensioning device or by adjusting the position of the driven sprocket 180. The adjustment assembly 170 is used for chain tensioning. During installation, it should be ensured that it can be easily operated and can effectively adjust the tension of the chain. During the installation process, the transmission chain 140 should be properly meshed with the transmission sprocket 130 and the driven sprocket 180 to avoid tooth skipping or chain jamming.

[0068] 3. Installation of telescopic folding part

[0069] First, the support plate 210 on one side of the free end of the telescopic folding part is connected to the transmission trolley 150. The connection method can be bolt connection or welding, etc., to ensure that the connection is firm and can withstand various forces during the extension and contraction of the telescopic folding part 200.

[0070] The folding portion 220 is installed on the support plate 210 . During installation, attention is paid to the folding direction and the flexibility of stretching and contraction of the folding portion 220 to ensure that it can be smoothly extended and contracted under the drive of the transmission trolley 150 .

[0071] Rollers 230 are installed below the bottom and on both sides of the support plate 210. The rollers 230 run on the guide rails 320. The rollers on both sides prevent left and right movement. The installation of the rollers 230 should ensure that they can rotate flexibly and the gap between them and the guide rails 320 is appropriate to avoid jamming. During installation, ensure that the installation position of the rollers 230 is accurate and can cooperate well with the guide rails 320 so that the telescopic folding part 200 can move smoothly during operation.

[0072] 2. Debugging and running

[0073] 1. Check before debugging

[0074] After the above installation is completed, comprehensively check the installation of each component to ensure that all bolt connections are tight, welding parts are firm, and there is no loose connection or excessive gap between components.

[0075] Check the connection of the electrical circuits to ensure that the wiring of electrical equipment such as the reduction motor 110 and the sensor 160 is correct and there are no short circuits, open circuits, etc. At the same time, check the settings and parameters of the control system (PLC controller) to ensure that they match the working requirements of the transmission components and the liquid contact mechanism.

[0076] Check the tension of the transmission chain 140, use a special tool or manually check to make its tension within a suitable range. If necessary, adjust it by adjusting the assembly 170.

[0077] Check the flexibility of the telescopic folding part 200, manually operate the transmission trolley 150, and observe whether the telescopic folding part 200 is smoothly extended and contracted, and whether the folding part 220 is stuck or deformed. At the same time, check the sealing performance of the telescopic folding part 200, and simulate the filtrate seepage. If there is any problem, make timely adjustments.

[0078] Check the rotation of the roller assembly 230 to ensure that it runs smoothly on the guide rail 320 without any jamming, and that the rollers on both sides can effectively prevent the support plate 210 from moving left and right.

[0079] 2. Debugging and running

[0080] Turn on the power supply, start the reduction motor 110, and make the transmission assembly drive the telescopic folding part 200 to slowly extend and retract, and observe the operation of each component. Adjust the speed of the reduction motor 110 through the PLC controller, observe the moving speed and stability of the transmission trolley 150, and whether the extension and retraction speed of the telescopic folding part 200 meets the design requirements. At the same time, observe the data collection of the sensor 160 to check whether it can accurately monitor the transmission speed, position and other parameters, and transmit the data to the control system.

[0081] The transmission system is fine-tuned according to the data fed back by the sensor 160. If the transmission speed is found to be unstable or deviates from the set value, it can be solved by adjusting the parameters of the reduction motor 110 or checking the tension of the transmission chain 140. If the position monitoring is inaccurate, the installation position of the sensor 160 can be checked or the parameters of the sensor can be calibrated.

[0082] During the debugging process, the liquid receiving effect of the telescopic folding part 200 is tested. A small amount of filtrate can be allowed to seep out under the simulated working state of the filter press to observe whether the telescopic folding part 200 can accurately receive the filtrate. If it is found that the liquid receiving effect is not good, factors such as the slope of the telescopic folding part 200 and the relative position of the filter press should be checked and corresponding adjustments should be made.

[0083] Observe the running condition of the roller 230 on the guide rail 320 to ensure that it runs smoothly without abnormal jumping or blocking. At the same time, check the anti-movement effect of the rollers on both sides on the support plate 210, and make appropriate adjustments if necessary.

[0084] 3. Official operation

[0085] When the debugging is completed and all indicators meet the requirements, the filter press can be officially put into operation. During the operation of the filter press, the telescopic liquid receiving mechanism will automatically operate according to the working status of the filter press.

[0086] When the filter press starts working, the control system starts the reduction motor 110 according to the preset program, and the transmission trolley 150 drives the telescopic folding part 200 to extend to catch the filtrate seeping from between the filter plates of the filter press. The sensor 160 monitors the operating status of the transmission system in real time, such as transmission speed, position, etc., and feeds back the data to the control system.

[0087] During the operation of the filter press, the telescopic liquid receiving mechanism is regularly inspected and maintained. The wear of the components, the connection of the electrical circuit, the working accuracy of the sensor 160, and whether the telescopic folding part 200 is damaged are mainly inspected. The wear of the roller assembly 230 is regularly inspected to ensure the smoothness and reliability of its operation on the guide rail 320. At the same time, check whether there is damage or foreign matter on the surface of the guide rail 320. If there is any problem, clean and repair it in time to ensure the normal operation of the roller assembly 230.

[0088] 4. Stop and maintain

[0089] When the filter press stops working or needs maintenance, the PLC controller issues a command to reverse the reduction motor 110, and the transmission trolley 150 drives the telescopic folding part 200 to shrink, thereby reducing the occupied space and facilitating the operator to perform maintenance and cleaning. During the maintenance process, each component can be inspected and maintained in detail. The entire liquid contact mechanism is regularly inspected and debugged to ensure that it can operate normally the next time it is used, and maintain good liquid contact effect and working performance.

[0090] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model. At the same time, in actual application, the specific installation method of the utility model can be appropriately adjusted and optimized according to factors such as the specific filter press model, working environment and process requirements to better meet the needs of actual production.
