[0013] Preferably, the cross-sectional size of the movable frame is smaller than the cross-sectional size of the socket, and the connecting frame is connected to the socket.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. The utility model uses a vacuum pump to connect a single group of gas-liquid separation cylinders, so that the adsorption tube and the desiccant tube are connected, and a control component is added in the adsorption tube and the desiccant tube. The action of the control component is realized by the controller, so as to control the opening and closing degree of the conduction frame to adjust the vacuum pressure of the adsorption area and the desiccant area. Since a vacuum pump is used, the workload of pipeline installation is reduced by half compared with that of using two vacuum pumps, and the operation and maintenance cost of a vacuum pump is half of that of two vacuum pumps, which greatly reduces the difficulty of pipeline assembly and the investment of vacuum pumps. In addition, the adsorption area and the desiccant area each become a The independent vacuum system is controlled by the control component in the vacuum pipeline. The adsorption system uses a smaller suction volume. For the filter fan operation that is completely closed under the filtrate surface, although a smaller suction volume is adopted, there is no waste of vacuum, so the filter fan in the adsorption area forms a filter cake with the maximum thickness. When the filter fan enters the de-drying area (using a larger suction volume), under this effect, the de-drying system can reach a relatively high vacuum value (if necessary, it can work above -0.08mpa), which can make the moisture content of the filtered material lower than that of the material filtered by a single vacuum filter by about 1 / 10, thereby providing convenience for downstream production.

[0016] 2. The utility model uses a single-pump dual-vacuum system when working, uses an independent drainage system in the adsorption area and adjusts the air extraction volume according to the material. When the filter machine starts working after each replacement of the filter bag, the vacuum degree of the adsorption system will increase rapidly in a short time (the vacuum value required for normal operation can be reached in about 10 minutes), and the adsorption layer will thicken rapidly; when the adsorbed material on the surface of the filter fan reaches a relative thickness and is transferred to the de-drying area, the vacuum value of the de-drying system will increase rapidly while adjusting the air extraction volume of the vacuum pump; the moisture content of the filtered material will also meet the standard in a short time, and this process can be completed in only about 1 / 10 of the time of the single vacuum filter 2, which can reduce the unqualified rate of moisture content of the filtered material by more than 90%. At the same time, due to the rapid thickening of the adsorption layer and the rapid closure of the filter disc, not only the vacuum output by the suction ore has fully done useful work, but the vacuum output by the de-drying has also been fully utilized, thereby reducing a lot of energy consumption.

[0017] 3. The utility model cooperates with the additional reprocessing component and the movable frame under the elastic connection to achieve the follow-up effect of the movable frame during the opening and closing control, and effectively shields the conductive hole. During the vacuum suction process, the inhaled gas and liquid are further filtered to remove residual solid particles, so that the gas and liquid finally filtered are purer, thereby obtaining a fully filtered liquid solution. The fully filtered liquid can be further post-processed to avoid residual liquid affecting subsequent liquid processing, thereby further improving the efficiency of subsequent liquid processing.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 8As shown, the embodiment of the utility model provides a single-pump dual-vacuum mechanism for a disc vacuum filter, comprising a base 1, a dual vacuum filter 2, a vacuum pump 3 and a gas-liquid separation cylinder 4, the two ends of the dual vacuum filter 2 are respectively fixedly connected with an adsorption tube 6 and a de-drying tube 15, a vacuum suction tube 5 is fixedly connected between the gas-liquid separation cylinder 4 and the vacuum pump 3, both sides of the gas-liquid separation cylinder 4 are fixedly connected with a conducting tube 7, the free ends of the two conducting tubes 7 are fixedly connected with a conducting frame 81, the two conducting frames 81 are respectively fixedly connected with the adsorption tube 6 and the de-drying tube 15, the top and bottom of the conducting frame 81 are respectively provided with a control component 10 and a reprocessing component 11, a controller 9 is fixedly provided at the bottom between the two control components 10, and the control component 10 controls the connection between the adsorption tube 6 and the de-drying tube 15 and the conducting tube 7;

[0029] The controller 9 includes a fixing seat 91, an air pump 92, a fixing frame 93, an extrusion plate 94, a spring 95 and a valve No. 1 96.

[0030] Embodiment 1: When in use, during filtering treatment, start the vacuum pump 3 and the double vacuum filter 2, the vacuum pump 3 sucks the air in the gas-liquid separation cylinder 4 through the vacuum suction pipe 5, keeps the No. 2 valve 14 closed, the internal air pressure of the gas-liquid separation cylinder 4 is reduced, so that a vacuum environment is formed in the conducting pipe 7, first start a group of No. 1 valves 96 in the controller 9, as the air pump 92 passes gas into the fixed frame 93, the air pressure increases and pushes the extrusion plate 94 to move upward, squeezing the hydraulic oil stored in the upper space, so that the spring 1 95 is stretched, and at the same time, the hydraulic oil is quickly passed through the opened No. 1 valve 96 to a group of control components 10 corresponding to the adsorption tube 6, the hydraulic oil fills the fixed tube 104 and pushes the push plate 103 to move upward, as the spring 2 105 is stretched, the curved rod 102 drives the sealing plate 101 to move upward, so that the conducting hole 82 is gradually opened, through The degree of opening and closing of the sealing plate 101 in the control component 10 intercepts or increases the amount of air pumped through the adsorption tube 6, so as to control the vacuum pressure of the adsorption zone of the filter, form a vacuum in the adsorption zone, and the gas and liquid in the double vacuum filter are sucked into the gas-liquid separation cylinder 4 through the adsorption tube 6, the conducting hole 82 and the conducting tube 7. When the dehydration treatment is carried out, the other group of No. 1 valves 96 are opened to activate the control component 10 corresponding to the dehydration tube 15, and the degree of opening and closing of the corresponding sealing plate 101 is intercepted or increased. The amount of air pumped through the dehydration tube 15 is controlled to control the vacuum pressure of the dehydration zone of the filter, form a vacuum in the dehydration zone, and the remaining gas and liquid are sucked into the gas-liquid separation cylinder 4 through the dehydration tube 15, the conducting hole 82 and the conducting tube 7. After the vacuum suction is completed, the No. 2 valve 14 is opened, and the sucked liquid is discharged outwardly through the outlet pipe 13.

[0031] First, by using a vacuum pump, in conjunction with the connection of a single group of gas-liquid separation cylinders 4, the adsorption tube 6 and the desiccant tube 15 are connected, and a control component 10 is added to the adsorption tube 6 and the desiccant tube 15, and the action of the control component 10 is realized by the controller 9, thereby controlling the opening and closing degree of the conduction frame 81 to adjust the vacuum pressure of the adsorption area and the desiccant area. Since a vacuum pump is used, the workload of pipeline installation is reduced by half compared with that of using two vacuum pumps, and the operation and maintenance cost of a vacuum pump 3 is half that of the maintenance cost of two vacuum pumps, which greatly reduces the difficulty of pipeline assembly and the investment capital of the vacuum pump 3, and the adsorption area and the desiccant area are each It becomes an independent vacuum system and is controlled by the control component 10 in the vacuum pipeline. The adsorption system uses a smaller suction volume. For the filter fan operation that is completely closed below the filtrate surface, although a smaller suction volume is adopted, there is no waste of vacuum, so the filter fan in the adsorption area forms a filter cake with the maximum thickness. When the filter fan enters the de-drying area (using a larger suction volume), under this effect, the de-drying system can reach a relatively high vacuum value (if necessary, it can work above -0.08 MPa), which can make the moisture content of the filtered material lower by about 1 / 10 than that of the material filtered by a single vacuum filter, thereby providing convenience for downstream production.

[0032] In addition, by using an independent drainage system in the adsorption area and adjusting the air extraction volume according to the material, the vacuum degree of the adsorption system will increase rapidly in a short time (the vacuum value required for normal operation can be reached in about 10 minutes) and the adsorption layer will thicken rapidly when the adsorption material on the surface of the filter fan reaches a relative thickness and is transferred to the de-drying area. Under the condition of adjusting the air extraction volume of the vacuum pump, the vacuum value of the de-drying system will increase rapidly. The moisture content of the filtered material will also meet the standard in a short time, and this process can be completed in only about 1 / 10 of the time of a single vacuum filter 3, which can reduce the unqualified rate of moisture content of the filtered material by more than 90%. At the same time, due to the rapid thickening of the adsorption layer and the rapid closure of the filter disc, not only the vacuum output by the adsorption ore has fully done useful work, but the vacuum output by the de-drying has also been fully utilized, thereby reducing a lot of energy consumption.

[0033] Embodiment 2: As the sealing plate 101 gradually moves upward to open the conducting hole 82, the movable frame 112 in the reprocessing assembly 11 moves upward under the elastic push of the bottom spring three 114, so that the movable frame 112 drives the internally connected auxiliary filter cloth 113 to move upward and cover the conducting hole 82. As the gas and liquid are sucked in, the solid particles in the mixed gas and liquid are further filtered on the side of the auxiliary filter cloth 113 to complete the reprocessing.

[0034] First, by cooperating with the added reprocessing component 11 and the movable frame 112 under the elastic connection, the follow-up effect of the movable frame 112 is realized during the opening and closing control, and the conductive hole 82 is effectively shielded. During the vacuum suction process, the inhaled gas and liquid are further filtered to remove residual solid particles, so that the gas and liquid finally filtered are purer, thereby obtaining a fully filtered liquid solution.

[0044] Through the air supply control of the controller 9, pneumatic thrust is used in conjunction with the squeezing and pushing effect of the internal hydraulic oil to achieve pressure control and control the actual opening and closing size and speed. The two groups of No. 1 valves 96 control the adsorption area and the dehydration area respectively, and the elasticity of the spring 95 facilitates reset.

[0045] Among them, the reprocessing component 11 includes a connecting frame 111, a movable frame 112, an auxiliary filter cloth 113 and a spring three 114.
