Therefore, the directional words used are used to illustrate rather than limit the invention.

[0019] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0020] Embodiment: A fully automatic chamber filter belt high-speed filter press, see attached Figure 1 , including a frame, a thrust plate 4, a push plate 3, a filter plate 2, a filter cloth belt 1 and a guide wheel group; the thrust plate 4 is fixed on the frame; the push plate 3 is slidably connected to the frame; the filter plates 2 are provided with multiple and arranged between the thrust plate 4 and the push plate 3; the filter cloth belt 1 passes through any two adjacent filter plates 2 and forms a closed loop, and two layers of filter cloth are formed between any two adjacent filter plates 2, and a filter cavity can be formed between the two layers of filter cloth, and the opening of the filter cavity faces downward; the guide wheel group is provided with multiple and is used to guide the filter cloth to pass through between two adjacent filter plates 2 and drive the filter cloth belt 1 to rotate.

[0021] When the filter press is working, the push plate 3 pushes the multiple filter plates 2 to move toward the thrust plate 4 and press them against the thrust plate 4. A filter cavity is formed between the two layers of filter cloth between two adjacent filter plates 2, and the filter material is input into the filter cavity. The liquid passes through the filter cloth and enters the filtrate discharge channel through the filter plate 2 and is discharged. The solid is trapped in the filter cavity to form a filter cake. After the filtration is completed, the push plate 3 moves away from the thrust plate 4 and drives the multiple filter plates 2 to separate from each other, and then drives the filter cloth belt 1 to move through the guide wheel group. During the movement, the filter cloth belt 1 will be deformed, so that the filter material adhered to the filter cloth belt 1 will be separated from the filter cloth belt 1 due to the deformation of the filter cloth belt 1, so that the filter cake can be quickly removed without manual intervention, so that the next filtration operation can be quickly carried out.

[0022] Specifically, the guide wheel group includes an upper roller 5, and an upper roller 5 is arranged above the space between two adjacent filter plates 2. The filter cloth belt 1 passes upward from between the two adjacent filter plates 2, passes through the upper roller 5, and enters between the two adjacent filter plates 2 again to form two layers of filter cloth between the two adjacent filter plates 2.

[0023] The upper roller 5 is arranged above two adjacent filter plates 2, and the filter cloth belt 1 is passed from the bottom of one filter plate 2 upwardly over the upper roller 5 and then downwardly over the bottom of the other filter plate 2, thereby forming two layers of filter cloth between the two filter plates 2, and the opening of the filter cavity formed between the two layers of filter cloth is facing downward, so that the filter cake can fall downward smoothly when unloading.

[0024] Specifically, the guide wheel group also includes a lower roller 6, and a lower roller 6 is arranged under each filter plate 2, and the filter cloth belt 1 is wound around the bottom of the lower roller 6. Through the arrangement of the lower roller 6, the filter cloth belt 1 can move between the gaps of adjacent filter plates 2.

[0025] Specifically, this embodiment further includes a cleaning mechanism, and the guide wheel group guides the filter cloth belt 1 to pass through the cleaning mechanism.

[0026] By setting the cleaning mechanism, after the filter cloth belt 1 is filtered between the filter plates 2, the part of the filter belt that has been filtered moves to the cleaning mechanism under the action of the guide wheel group, and the filter cloth belt 1 moved out of the cleaning mechanism moves between the filter plates 2, thereby ensuring that while performing a filter press, the cleaning mechanism can clean the part of the filter belt that was filtered last time, thereby eliminating the need to clean the filter cloth belt 1 separately, thereby ensuring the cyclicity of the filter press operation and truly realizing continuous filter press work.

[0027] The cleaning mechanism comprises a cleaning tank 7 and a nozzle 8, and the filter cloth belt 1 passes through the cleaning tank 7 or above the cleaning tank 7; at least one nozzle 8 for spraying water toward the filter cloth is arranged on both sides of the filter cloth.

[0028] When the filter cloth belt 1 moves to the cleaning tank 7 or moves above the cleaning tank 7, the nozzle 8 sprays clean water through both sides of the filter cloth belt 1 to flush the filter cloth belt 1.

[0029] In the present embodiment, in order to ensure that the filter cloth undergoing pressure filtration can be cleaned at the cleaning tank 7 at the same time, a plurality of staggered auxiliary wheels are arranged on the guide wheel group, and a serpentine state is formed in the cleaning tank 7 by the filter cloth belt 1 passing through the plurality of auxiliary wheel groups in sequence, thereby increasing the length of the filter cloth belt 1 accommodated in the unit space of the cleaning tank 7, and ensuring that the cleaning tank 7 can simultaneously clean the filter cloth belt 1 undergoing pressure filtration.

[0030] Similarly, in order to ensure the cleanliness of the filter cloth, the cleaning mechanism can also be provided with a cleaning roller brush or other auxiliary equipment for cleaning the filter cloth belt 1 in addition to the nozzle 8. Here, this patent does not limit the type of specific cleaning equipment.

[0031] Specifically, the guide wheel group includes a steering wheel, at least one of which is provided, and the first steering wheel is used to guide the filter cloth belt 1 to move from the filter plate 2 to the cleaning mechanism.

[0032] Specifically, the guide wheel group also includes a Shub wheel 9, which is used to guide the filter cloth belt 1 to move from the cleaning mechanism to the filter plate 2 and to stretch the filter cloth belt 1 so that the filter cloth belt 1 is evenly distributed between adjacent filter plates 2.

[0033] By setting the Shub wheel 9, the filter cloth belt 1 can be flattened in at least the left and right directions before entering between the filter plates 2, so that the filter cloth entering between the filter plates 2 can remain flat, thereby ensuring the sealing of the filter cavity formed between the two filter plates 2, thereby ensuring the effect of filter pressure.

[0034] Specifically, the guide wheel assembly further includes a tensioning wheel 11, and the tensioning wheel 11 drives the filter cloth belt 1 on the guide wheel assembly to be in a tensioned state by sliding.

[0035] Specifically, the guide wheel group includes a deviation correction wheel 10, and the deviation correction wheel 10 is used to correct the left-right deviation of the filter cloth belt 1.

[0036] Specifically, the filter plate 2 is configured as a filter plate 2 with a diaphragm, and the diaphragm is flushed with high-pressure gas or liquid to squeeze the filter plate 2 in the filter cavity between two adjacent filter plates 2.

[0037] The provision of the filter plate 2 with the diaphragm can increase the pressure when squeezing the filter material in the filter cavity, further improve the filtering effect, and reduce the water content of the filter cake finally formed.

[0038] Specifically, in this embodiment, a hydraulic cylinder is provided on the frame of the filter press to push the push plate 3 to slide on the frame; the remaining structure of the filter press and the specific structure of the filter plate 2 are the same as those of the traditional filter press and will not be described in detail in this embodiment.

[0039] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
