Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically a telmisartan filter press device. Background Technology

[0002] Telmisartan is a widely used drug for the treatment of cardiovascular diseases, and its production quality control is of paramount importance. In the telmisartan production process, pressure filtration is a key step in removing impurities and improving product purity.

[0003] Currently, filter presses are generally used for filtration. However, after filtration, filter cake remains on the filter plates. Since the filter plates are located inside the filter press, it is difficult for workers to remove the filter plates and recycle the filter cake. Specifically, filter presses are usually quite deep, and workers need to use specific tools to operate in a limited space, which is not only time-consuming and labor-intensive but also inefficient. Therefore, a telmisartan filter press device is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a telmisartan pressure filtration device that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the telmisartan pressure filtration device proposed in this utility model includes a tank body, a tank cover at the top of the tank body, a tank cover opening mechanism, a support member fixedly connected to the inner wall of the tank body for supporting filter plates, a pressing mechanism above the filter plates, and a limit assembly on the tank body. The pressing mechanism includes:

[0006] An electric cylinder, which is fixedly mounted on the can lid;

[0007] A fixing component, which is connected to the output end of the electric cylinder;

[0008] A pressure plate, located at the bottom of the fixing assembly, has a trapezoidal cross-section.

[0009] Preferably, the fixing component includes a connector, the bottom of which is fixed to the pressure plate, the connector is penetrated by a locking block and slidably connected to the locking block, a T-rod is fixedly connected to the outer wall of the locking block, a hinged rod is hinged to the T-rod, and a vertical rod is hinged to the end of the hinged rod away from the T-rod.

[0010] Preferably, the T-bar and the connector are elastically connected by a connecting spring, and the vertical rod passes through the connector and is slidably connected to the connector.

[0011] Preferably, a connecting column is fixedly connected to the upper side of the filter plate, and a limiting groove is formed on the outer wall of the connecting column.

[0012] Preferably, the pressure plate has a through groove in the middle, which matches the connecting column. The connector has a groove in the middle, and the diameter of the groove matches the connecting column. By activating the electric cylinder, the output end of the electric cylinder drives the connector to descend, which in turn drives the pressure plate to descend, so that the pressure plate can filter the raw material on the filter plate. After the filter is completed, the output end of the electric cylinder drives the connector to rise. After the limiting groove limits the locking block, the connector continues to rise, which will drive the connecting column and the filter plate to rise.

[0013] Preferably, the limiting component includes a limiting block, a connecting rod fixedly connected to the outer wall of the limiting block, and a ring fixedly connected to the end of the connecting rod away from the limiting block. The ring is elastically connected to the outer wall of the tank through a return spring. The ring is rotatably connected to a handle. A limiting rod is fixedly connected to the outer wall of the tank. After the connecting column and the filter plate rise, they will squeeze the limiting block, which will compress the return spring. After the filter plate passes the limiting block, the return spring will drive the limiting block to reset. Then, the vertical rod is squeezed by the inner wall of the tank cover, which will drive the hinge rod to move. This will cause the T-rod to drive the locking block away from the limiting groove, and the limiting of the connecting column will be released. The filter plate will then descend back to the limiting block, making it easier to remove the filter plate after opening the tank cover and to recover the filter cake on the filter plate. By pulling and rotating the handle, the handle is limited by the limiting rod, and the limiting block compresses the return spring and retracts into the tank, making it easier to put the cleaned filter plate back onto the support.

[0014] Preferably, the opening mechanism includes a connecting plate, which is fixedly connected to the top of the can lid. The connecting plate is hinged to a swing arm, which is hinged to a connecting block. The connecting block is fixedly connected to the telescopic end of an electric telescopic rod. The sleeve of the electric telescopic rod is hinged to a bracket, which is fixedly connected to the can body. The swing arm is hinged to the bracket. By retracting the telescopic end of the electric telescopic rod, the swing arm can be rotated, thereby opening the can lid.

[0015] This invention provides a telmisartan pressure filtration device. It has the following beneficial effects:

[0016] (1) The coordinated design of the pressing mechanism and the limiting component of the telmisartan filter press allows the filter plate and filter cake to be easily lifted together after the filter press is completed. The limiting component can limit the position of the filter plate and at the same time, it is convenient to release the limiting of the filter plate so that the filter plate can fall back to a position that is easy to remove. This greatly simplifies the process of removing the filter plate from the tank and recovering the filter cake, improves work efficiency and reduces material waste.

[0017] (2) The telmisartan filter press uses components such as electric telescopic rods and swing arms. The tank cover can be opened automatically by starting the electric telescopic rod, which is simple and labor-saving. At the same time, the limiting component plays a key auxiliary role in the installation and removal of the filter plate. Pulling and turning the handle can adjust the position of the limiting block, making it convenient to put the cleaned filter plate back. The overall operation is convenient and efficient.

[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model proposes a telmisartan pressure filtration device, including a tank body 1, a tank cover 2 on the top of the tank body 1, a cover opening mechanism 3 on the tank cover 2, a support member 4 fixedly connected to the inner wall of the tank body 1, the support member 4 is used to support the filter plate 5, a pressing mechanism 6 is provided above the filter plate 5, and a limit component 7 is provided on the tank body 1.

[0030] In an embodiment of this utility model, in order to filter the telmisartan intermediate by pressure, the pressing mechanism 6 specifically includes an electric cylinder 61, a fixing component 62, and a pressure plate 63. The electric cylinder 61 is fixedly installed on the can cover 2, the fixing component 62 is connected to the output end of the electric cylinder 61, and the pressure plate 63 is located at the bottom of the fixing component 62. By activating the electric cylinder 61, the fixing component 62 and the pressure plate 63 are driven to descend, thereby driving the pressure plate 63 to squeeze the telmisartan intermediate on the filter plate 5, thereby realizing the pressure filtration of the telmisartan intermediate.

[0031] Furthermore, in order to bring up the filter plate 5 after the filter press is completed, making it easier to remove the filter cake from the filter plate 5, the fixing component 62 specifically includes a connector 621. The bottom of the connector 621 is fixed to the pressure plate 63. The connector 621 is penetrated by a locking block 622 and is slidably connected to the locking block 622. A T-rod 623 is fixedly connected to the outer wall of the locking block 622. A hinge rod 624 is hinged to the T-rod 623. A vertical rod 625 is hinged to the end of the hinge rod 624 away from the T-rod 623. The T-rod 623 and the connector 621 are elastically connected by a connecting spring. Rod 625 passes through connector 621 and is slidably connected to connector 621. Connecting column 51 is fixedly connected to the upper side of filter plate 5. Limiting groove 52 is opened on the outer wall of connecting column 51. Through groove is opened in the middle of pressure plate 63 and the through groove matches connecting column 51. Groove is opened in the middle of connector 621 and the diameter of the groove matches connecting column 51. After the filter is pressed, the output end of electric cylinder 61 drives connector 621 to rise. After limiting groove 52 limits block 622, connector 621 continues to rise, which will drive connecting column 51 and filter plate 5 to rise.

[0032] Furthermore, the limiting component 7 includes a limiting block 71, a connecting rod 72 fixedly connected to the outer wall of the limiting block 71, and a ring 73 fixedly connected to the end of the connecting rod 72 away from the limiting block 71. The ring 73 is elastically connected to the outer wall of the tank body 1 through a return spring. The ring 73 is rotatably connected to a handle 74. A limiting rod 75 is fixedly connected to the outer wall of the tank body 1. The pressure plate 63 has a trapezoidal cross-section. This shape design allows the limiting block 71 to be squeezed and moved when the pressure plate 63 descends. The pressure plate 63 can pass through the limiting block 71, and the return spring drives the limiting block 71 to return to its original position. Afterward, the vertical rod 625 is moved by the inner edge of the can lid 2. The wall compression causes the hinge rod 624 to move, which in turn causes the T rod 623 to move the locking block 622 away from the limiting groove 52. The limiting of the connecting column 51 is released, and the filter plate 5 descends back to the limiting block 71, making it easier to remove the filter plate 5 after opening the tank cover 2 and to recover the filter cake on the filter plate 5. By pulling and turning the handle 74, the handle 74 is limited by the limiting rod 75. The limiting block 71 compresses the reset spring and retracts into the inside of the tank body 1, making it easier to put the cleaned filter plate 5 back onto the support 4. This greatly simplifies the process of removing the filter plate 5 from the tank body 1 and recovering the filter cake, improves work efficiency, and reduces material waste.

[0033] Furthermore, the opening mechanism 3 includes a connecting plate 31, which is fixedly connected to the top of the can lid 2. The connecting plate 31 is hinged to a swing arm 32, which is hinged to a connecting block 33. The connecting block 33 is fixedly connected to the telescopic end of the electric telescopic rod 34. The sleeve of the electric telescopic rod 34 is hinged to a bracket 35, which is fixedly connected to the can body 1. The swing arm 32 is hinged to the bracket 35. By starting the telescopic end of the electric telescopic rod 34 to retract, the swing arm 32 can be driven to rotate, thereby opening the can lid 2. After the telescopic end of the electric telescopic rod 34 extends, the swing arm 32 rotates back, allowing the can lid 2 to close.

[0034] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that each electrical appliance can work normally. For example, the electric cylinder 61 and the electric telescopic rod 34 are both connected to the mains power. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0035] In use, first start the electric cylinder 61, which drives the fixing component 62 and the pressure plate 63 to descend, thereby driving the pressure plate 63 to squeeze the telmisartan intermediate on the filter plate 5. After the filtration is completed, the output end of the electric cylinder 61 drives the connecting piece 621 to rise. After the limiting groove 52 limits the locking block 622, the connecting piece 621 continues to rise, which will drive the connecting column 51 and the filter plate 5 to rise. When the pressure plate 63 descends, the limiting block 71 can be squeezed and moved. The pressure plate 63 can pass through the limiting block 71, and the return spring drives the limiting block 71 to return to its original position. Then, the vertical rod 625 is squeezed by the inner wall of the can cover 2, which drives the hinge rod 624 to move, thereby causing the T rod 623 to drive the locking block 622 away from the limiting groove 52. The limiting of the connecting column 51 is released, and the filter plate 5 descends again to the limiting block 71. Then, by starting the extension end of the electric telescopic rod 34 to retract, the swing arm 32 can be rotated to open the can cover 2. Then, the filter plate 5 is taken out for filter cake recycling and the filter plate 5 is cleaned.
