Description

Technical Field

[0001] The utility model relates to the technical field related to filter press devices, in particular to a filter press device after copper sulfide is precipitated from cuprous cyanide waste liquid. Background Art

[0002] Cuprous cyanide is mainly used for electroplating copper and its other alloys, synthesizing tuberculosis drugs and antifouling coatings. The wastewater generated in its production contains mixed salts of sodium chloride and sodium sulfate. If it is directly discharged without treatment, it will cause serious environmental damage.

[0003] Sodium hypochlorite is added to the treatment of cuprous cyanide production wastewater to remove cyanide ions in the cuprous cyanide production wastewater, and then sodium sulfide is added to the cuprous cyanide production wastewater to remove copper ions in the cuprous cyanide production wastewater. By performing filter press treatment on the cuprous cyanide production wastewater, filtrate and filter cake containing copper sulfide can be obtained. The filter press device uses a special filter medium to apply a certain pressure to the object to make the liquid seep out. It is a mechanical equipment and is a commonly used solid-liquid separation device.

[0004] After the existing filter press device separates the filter plates, the filter cake is separated from the filter plates by automatically falling. However, there is a certain adhesion between the filter cake and the filter plates, which will cause part of the filter cake to be unable to automatically separate from the filter plates without the action of external forces. Therefore, it is necessary to manually separate the filter plates from the filter cake, which is not conducive to improving work efficiency. Utility Model Content

[0030] See also Figure 1-Figure 6 In the embodiment of the utility model, the filter press device after the copper sulfide is precipitated from the cuprous cyanide waste liquid comprises a frame 1 and a frame 2 fixed on the back of the frame 1, a plurality of evenly distributed filter plates 3 are arranged inside the frame 1, a driving assembly 4 is arranged inside the frame 2, a mounting box 5 is arranged on the top of the frame 2, a fixed shaft 6 is fixedly arranged inside the mounting box 5, an external sliding sleeve of the fixed shaft 6 is provided with an insertion rod 7, and a steering assembly 8 and a pushing assembly 9 are arranged inside the mounting box 5;

[0031] The driving assembly 4 is used to drive the installation box 5 to move left and right, thereby adjusting the position of the insertion rod 7, so that the adjacent filter plates 3 can be separated, and the filter cakes on both sides of the filter plates 3 can fall;

[0032] The steering assembly 8 is used for rotating the insertion rod 7 so that the insertion rod 7 is inserted into the filter plate 3 or moves away from the filter plate 3;

[0033] The pushing component 9 is used to drive the insertion rod 7 to move back and forth. When the insertion rod 7 is inserted into the filter plate 3, the pushing component 9 can drive the filter plate 3 to vibrate left and right through the insertion rod 7, thereby shaking off the filter cakes adhered to both sides of the filter plate 3;

[0034] Under the action of the driving assembly 4, the installation box 5 is stably moved, so that the insertion rod 7 can act on each filter plate 3, and cooperate with the steering assembly 8 and the pushing assembly 9 to shake each filter plate 3;

[0035] The position of the plug rod 7 can be automatically adjusted by the steering assembly 8, so that the plug rod 7 is automatically inserted into the filter plate 3, or separated from it, without manual operation, and is convenient to use;

[0036] By means of the setting of the pushing component 9, when the steering component 8 operates the plug rod 7 to engage with the filter plate 3, the pushing component 9 reciprocates the plug rod 7 left and right, and the plug rod 7 acts on the filter plate 3, and the filter plate 3 vibrates, so that the filter cake in the filter plate 3 that is difficult to fall automatically can be shaken off, and there is no need to manually separate the filter plate 3 from the filter disease, thereby achieving the effect of automated processing, which is conducive to improving work efficiency.

[0037] See also Figure 4 The filter plate 3 includes a filter frame 301, and support frames 302 are fixedly provided on both sides of the filter frame 301. A slot 303 is provided inside the support frame 302, and the slot 303 cooperates with the insertion rod 7;

[0038] By inserting the insertion rod 7 into the interior of the slot 303, cooperating with the steering assembly 8 and the pushing assembly 9, the filter plate 3 can be shaken, and the support frame 302 can be located on the frame 1 to support the filter plate 3. The slot 303 is arranged inside the support frame 302, which neither affects the use of the support frame 302 nor the overall structure of the filter frame 301.

[0039] See also Figure 3 The driving assembly 4 includes a threaded rod 401 and a driving motor 402. The driving end of the driving motor 402 is fixedly connected to the threaded rod 401. The threaded rod 401 is rotatably arranged inside the frame 2. The driving motor 402 is fixedly arranged on one side of the frame 2. The installation box 5 is threadedly connected to the outside of the threaded rod 401. A rectangular groove is opened inside the frame 2. The threaded rod 401 is rotatably arranged inside the rectangular groove, and the bottom of the installation box 5 is arranged inside the rectangular groove.

[0040] The threaded rod 401 is driven to rotate by the driving motor 402. Since the installation box 5 is threadedly connected to the threaded rod 401 and the rectangular groove plays a limiting role, the installation box 5 is driven to move left and right, and then the insertion rod 7 is driven to move. After the insertion rod 7 is inserted into the filter plate 3, the adjacent filter plates 3 can be separated under the action of the driving motor 402, and the filter cake in the filter plate 3 can automatically fall off downward. The cooperation of the driving motor 402 and the threaded rod 401 can realize the precise adjustment of the position of the installation box 5. At the same time, the installation box 5 can be adjusted over a longer distance.

[0041] See also Figure 6 The steering assembly 8 includes a cylinder 801, a transmission rod 802 is fixedly arranged on the top of the cylinder 801, and connection grooves 803 are provided at both ends of the bottom of the insertion rod 7, and the two ends of the transmission rod 802 are respectively slidably arranged inside the two connection grooves 803;

[0042] It also includes a slider 804 and a slide rail 805. The slider 804 is slidably disposed inside the slide rail 805. The bottom of the cylinder 801 is fixedly connected to the slider 804.

[0043] The transmission rod 802 is pushed up and down by the cylinder 801, and the transmission rod 802 slides inside the connection groove 803, which can drive the insertion rod 7 to rotate around the fixed shaft 6, so that the insertion rod 7 is inserted into the slot 303 on one side of the filter plate 3 or is separated from the slot 303. When the insertion rod 7 is inserted into the slot 303, the corresponding filter plate 3 can be shaken left and right in cooperation with the pushing component 9, and the filter plate 3 generates vibration to shake off the filter cake;

[0044] Under the action of the slider 804 and the slide rail 805 , when the pushing assembly 9 pushes the insertion rod 7 to move left and right, the cylinder 801 moves synchronously, which neither affects the adjustment effect on the insertion rod 7 nor affects the effect of the pushing assembly 9 on the insertion rod 7 .

[0045] See also Figure 1 The pushing assembly 9 includes a pushing motor 901, a cam 902 and a return spring 903. The driving end of the pushing motor 901 is fixedly connected to the cam 902. The pushing motor 901 is fixedly arranged inside the installation box 5. The return spring 903 is sleeved on the outside of the fixed shaft 6.

[0046] When the plug rod 7 is inserted into one side of the filter plate 3, the cam 902 is driven to rotate continuously by the push motor 901. When the cam 902 contacts the plug rod 7, the plug rod 7 is forced to move to the side away from the push motor 901 and squeeze the reset spring 903. When the cam 902 is not in contact with the plug rod 7, the plug rod 7 is reset under the action of the reset spring 903. As the cam 902 continues to rotate, the plug rod 7 repeatedly moves left and right to generate vibration, thereby shaking off the filter cake attached to the filter plate 3. The motor required in the push motor 901 has a simple structure and a lower manufacturing cost. If a failure occurs, it is relatively easy to repair.

[0047] See also Figure 1 and Figure 2 A hydraulic cylinder 10 is provided on one side of the frame 1, and a pressure plate 11 is fixedly provided on one side of the piston rod of the hydraulic cylinder 10. The pressure plate 11 is provided inside the frame 1, and the pressure plate 11 squeezes a plurality of filter plates 3 through the hydraulic cylinder 10;

[0048] The side of the frame 1 away from the hydraulic cylinder 10 is connected with an injection pipe 12 for introducing cuprous cyanide wastewater into the filter plate 3;

[0049] When the hydraulic cylinder 10 is started, the pressing plate 11 is pushed to move toward the filter plate 3, and the pressing plate 11 squeezes the multiple filter plates 3. Then, cuprous cyanide wastewater is injected into the filter plates 3 through the injection pipe 12 to obtain filtrate and filter cake containing copper sulfide. Then, the hydraulic cylinder 10 drives the pressing plate 11 to move in the opposite direction and reset, and then the filter cake is shaken off through the cooperation of the driving component 4, the steering component 8 and the pushing component 9.
