Description

Technical Field

[0001] The utility model relates to the technical field of filter plate pressure testing, in particular to a roller rack filter plate force testing device. Background Art

[0002] A filter press is a mechanical device that uses a special filtering medium to apply a certain pressure to an object to allow liquid to dialyze out. It is a commonly used solid-liquid separation device and is applied in industries such as chemical engineering, pharmaceuticals, metallurgy, dyes, food, brewing, ceramics, and environmental protection. When the filter press is working, it needs to pressurize the filter plate so that the filter plate separates the solid and liquid. Therefore, during use, a pressure testing device is required to test the pressure of components such as the filter plate to avoid damage during filtration when the component pressure test is unqualified.

[0003] However, in the prior art, when the roller rack filter plate force testing device conducts a transportation and die testing pressure on the filter plate, it lacks a fixing structure, and the filter plate cannot accurately dock with the fixing plate, resulting in a poor die-clamping effect of the two fixing plates, thus affecting the filter plate pressure test.

The filter plate body is movably placed on the upper side of the plurality of roller bodies.

[0008] As a preferred embodiment, the two moving components include two transverse grooves, and the two transverse grooves are symmetrically opened on the top surface of the bottom plate.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In this utility model, the pressing water can be added through the water filling port on the top surface of the water tank. When it is necessary to conduct a pressure test on the filter plate body, first, the control terminal operates multiple first motors. The operation of the multiple first motors drives the rotation of four of the rotating rods. The rotation of the four rotating rods drives the rotation of two pulleys and the roller body on their surfaces. Every two of the multiple pulleys are connected by a transmission belt, so that the multiple pulleys rotate synchronously, and further the multiple roller bodies rotate synchronously. Subsequently, the filter plate body is placed above the multiple roller bodies, and the filter plate body moves through the rotation of the multiple roller bodies. When one side surface of the filter plate body abuts against one side of the T-shaped fixing plate, at this time, the control terminal stops operating the multiple first motors and operates two electric telescopic rods. The telescopic ends of the two electric telescopic rods perform telescopic movement to drive the movement of two clamping plates. The movement of the two clamping plates drives the movement of two support rods on one side surface of them inside the U-shaped plate. The movement of the two clamping plates cooperates with multiple anti-slip strips on their surfaces to firmly clamp and fix the filter plate body. At the same time, the movement of the two clamping plates drives the movement of two hinge plates, and the movement of the two hinge plates drives the outward movement of the T-shaped fixing plate. When the filter plate body is clamped, at this time, the control terminal operates two second motors. The operation of the two second motors drives the rotation of two threaded rods. The rotation of the two threaded rods drives the movement of two T-shaped plates on the surfaces of two cross bars. The movement of the two T-shaped plates causes the bottom surface of the filter plate body to separate from the multiple roller bodies. When the multiple conveying components no longer obstruct the movement of the lower fixing plate, at this time, the control terminal stops operating the two second motors and operates multiple hydraulic cylinders. The operation of the multiple hydraulic cylinders drives the upward movement of the lower fixing plate. When the bottom end surface of the filter plate body is embedded in the groove body opened on the surface of the lower fixing plate, at this time, the two electric telescopic rods are operated in the reverse direction, so that the two clamping plates are separated from the filter plate body. At the same time, the T-shaped fixing plate does not obstruct the movement of the lower fixing plate. The filter plate body is driven by the lower fixing plate to move upward and is combined with the upper fixing plate for pressurization. The control terminal presets the starting pressure to control the hydraulic cylinder to push the lower fixing plate upward to apply pressure to the filter plate body clamped inside the lower fixing plate and the upper fixing plate. After the pressurization is completed, the control terminal operates a water pump. The operation of the water pump conveys the pressing water inside the water tank to the inside of the filter plate body through a water injection pipe. While injecting water, a remote pressure gauge measures the pressure of the pressing water entering the filter plate body, converts the pressure into an electrical signal and transmits it to the control terminal for monitoring. Through the cooperation of the above structures, the filter plate body can be conveyed by multiple roller bodies, and the filter plate body can be accurately positioned directly above the lower fixing plate through the positioning component, which is convenient for the subsequent combination of the lower fixing plate and the upper fixing plate and ensures that the subsequent pressure test can be carried out normally.

[0032] In one embodiment, the positioning component 10 includes two electric telescopic rods 1001 which are fixedly installed on the inner wall surfaces on both sides of the U-shaped plate 2.

Multiple anti-slip strips are fixedly installed on one side surface of the two clamping plates 1002, and two support rods 1003 are fixedly installed on the other side surface of the two clamping plates 1002. The multiple support rods 1003 correspondingly and movably penetrate through the inner wall surfaces on both sides of the U-shaped plate 2, and limit plates are fixedly installed at the end ports of one ends of the multiple support rods 1003.

[0033] Specifically, the two electric telescopic rods 1001 play a role in driving the two clamping plates 1002 to move, the support rod 1003 plays a role in ensuring the stable movement of the clamping plates 1002, and multiple anti-slip strips (not marked in the figure) play a role in ensuring that the two clamping plates 1002 can firmly clamp the filter plate body 5.

[0034] In one embodiment, hinge plates 1004 are hinged to the surfaces of one ends of the two clamping plates 1002, a T-shaped fixing plate 1005 is hinged between the two hinge plates 1004, and one side surface of the T-shaped fixing plate 1005 is in movable contact with one side surface of the filter plate body 5.

[0036] In one embodiment, the water injection assembly 11 includes a water tank 1101, the water tank 1101 is fixedly installed on one side of the top surface of the U-shaped plate 2, a water pump 1102 is fixedly installed on one side surface of the water tank 1101, the input end of the water pump 1102 is connected to the water tank 1101 in a through manner, the output end of the water pump 1102 is connected to a water injection pipe 1103 in a through manner, a remote pressure gauge 1104 is fixedly arranged on the outer wall surface of the water injection pipe 1103, and one end of the water injection pipe 1103 penetrates through the top surface of the U-shaped plate 2 and is connected to the inside of the fixing plate 402 in a through manner.

[0037] Specifically: the remote pressure gauge 1104 is a device for testing water pressure in the prior art, is connected to the control terminal 3, and can detect the water pressure after running. The specific structure will not be elaborated here.

[0038] Working principle: Pressurized water can be added through the water filling port on the top surface of the water tank 1101. When it is necessary to conduct a pressure test on the filter plate body 5, first, the control terminal 3 operates multiple first motors 807. The operation of the multiple first motors 807 drives the rotation of four of the rotating rods 802. The rotation of the four rotating rods 802 drives the rotation of two pulley wheels 804 and the roller body 803 on their surfaces. Every two of the multiple pulley wheels 804 are connected by a transmission belt 805, so that the multiple pulley wheels 804 rotate synchronously, and then the multiple roller bodies 803 rotate synchronously. Subsequently, the filter plate body 5 is placed above the multiple roller bodies 803, so that the filter plate body 5 moves by the rotation of the multiple roller bodies 803. When one side surface of the filter plate body 5 abuts against one side of the T-shaped fixing plate 1005, at this time, the control terminal 3 stops operating the multiple first motors 807 and operates two electric telescopic rods 1001. The telescopic ends of the two electric telescopic rods 1001 perform telescopic movement to drive the movement of two clamping plates 1002. The movement of the two clamping plates 1002 drives the movement of two support rods 1003 on one side surface thereof inside the U-shaped plate 2. The movement of the two clamping plates 1002 cooperates with multiple anti-slip strips on their surfaces to firmly clamp and fix the filter plate body 5. At the same time, the movement of the two clamping plates 1002 drives the movement of two hinge plates 1004, and the movement of the two hinge plates 1004 drives the T-shaped fixing plate 1005 to move outwards. When the filter plate body 5 is clamped, at this time, the control terminal 3 operates two second motors 903. The operation of the two second motors 903 drives the rotation of two threaded rods 904. The rotation of the two threaded rods 904 drives the movement of two T-shaped plates 7 on the surfaces of two cross bars 902. The movement of the two T-shaped plates 7 causes the bottom surface of the filter plate body 5 to separate from the multiple roller bodies 803. When the multiple conveying components 8 no longer obstruct the movement of the lower fixing plate 404, at this time, the control terminal 3 stops operating the two second motors 903 and operates multiple hydraulic cylinders 403. The operation of the multiple hydraulic cylinders 403 drives the upward movement of the lower fixing plate 404. When the bottom end surface of the filter plate body 5 is embedded in the groove body formed on the surface of the lower fixing plate 404, at this time, the two electric telescopic rods 1001 are operated in the reverse direction, so that the two clamping plates 1002 are separated from the filter plate body 5. At the same time, the T-shaped fixing plate 1005 does not obstruct the movement of the lower fixing plate 404. The filter plate body 5 is driven to move upward by the lower fixing plate 404 and is clamped and pressurized with the upper fixing plate 402. The control terminal 3 preset start-up pressure is used to control the hydraulic cylinder 403 to push the lower fixing plate 404 upward to apply pressure to the filter plate body 5 clamped between the inner sides of the lower fixing plate 404 and the upper fixing plate 402. After the pressure application is completed, the control terminal 3 operates the water pump 1102. The operation of the water pump 1102 conveys the pressurized water inside the water tank 1101 to the inside of the filter plate body 5 through the water injection pipe 1103. While injecting water, the remote pressure gauge 1104 measures the pressure of the pressurized water entering the filter plate body 5, converts the pressure into an electrical signal and transmits it to the control terminal 3 for monitoring. Through the cooperation of the above structures,The filter plate body 5 can be conveyed by multiple roller bodies 803. The filter plate body 5 is accurately positioned directly above the lower fixed plate 404 through the positioning component 10, which facilitates the subsequent mold closing of the lower fixed plate 404 and the upper fixed plate 402 and ensures the normal progress of subsequent pressure tests.

[0039] The above are only the preferred embodiments of the present invention, and are not limitations on the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
