Description

Technical Field

[0001] The utility model relates to the field of phenolic resin wastewater, and in particular to a centrifugal separation device for treating phenolic resin wastewater. Background Art

[0002] Phenolic resin wastewater refers to wastewater generated during the phenolic resin production process. This wastewater contains high concentrations of organic matter such as phenol, aldehyde, and resin. Its high organic matter concentration, high toxicity, and low pH value pose a serious threat to the environment. Phenolic resin wastewater requires treatment during discharge. Centrifugal separation equipment is used to effectively separate suspended solids from the solvent in the wastewater, thereby extracting useful substances from the wastewater.

[0003] The existing centrifugal separation device for treating phenolic resin wastewater simply pours the extractant and wastewater into a rotating drum and then separates them by centrifugation. However, when separating the phenolic resin wastewater, it is impossible to directly mix and disperse the wastewater and the extractant quickly, so that the extractant cannot fully contact with the phenolic substances in the wastewater and a mass transfer process cannot occur, thereby affecting the separability of the phenolic resin wastewater.

[0004] Therefore, it is necessary to invent a centrifugal separation device for phenolic resin wastewater treatment to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a centrifugal separation device for treating phenolic resin wastewater. The centrifugal separation device comprises the following steps: the phenolic resin wastewater and an extractant are respectively poured into a centrifugal drum in a separation tank through a water inlet, and a baffle driven by a cylinder is used to block the filter holes outside the centrifugal drum to prevent the phenolic resin wastewater and the extractant from overflowing before they are mixed. Then, a first drive motor switch is turned on to drive a transmission rod and a stirring blade to rotate, so that the extractant and the phenolic substances in the wastewater are fully contacted and a mass transfer process occurs. Finally, after mixing is completed, the baffle is retracted by the cylinder, and then a second drive motor switch is turned on to drive the centrifugal drum to rotate, so that the phenolic resin wastewater and the extractant in the centrifugal drum are centrifugally separated. The utility model solves the problem that the existing centrifugal separation device for treating phenolic resin wastewater proposed in the above-mentioned background art only pours the extractant into a rotating drum together with the wastewater and then separates them by centrifugation. However, when the phenolic resin wastewater is separated, the wastewater and the extractant cannot be directly mixed and dispersed quickly, so that the extractant cannot fully contact the phenolic substances in the wastewater and a mass transfer process cannot occur, thereby affecting the separability of the phenolic resin wastewater.

[0006] In order to achieve the above-mentioned object, the present utility model provides the following technical solutions: a centrifugal separation device for treating phenolic resin wastewater, comprising a separation tank;

[0007] An upper cover is installed above the separation tank for disassembly. Bolts are threaded through both sides of the upper cover. A water inlet is provided on one side above the upper cover, and a drain pipe is provided on one side below the separation tank.

[0008] A stirring mechanism is provided above the upper cover and is used for stirring;

[0009] A centrifugal cylinder is provided inside the separation tank for centrifugal separation. A second drive motor is provided below the separation tank. The output end of the second drive motor is fixedly connected to the centrifugal cylinder. The outside of the centrifugal cylinder is provided with filter holes.

[0010] The shielding assembly is installed inside the separation tank and is used to block the centrifugal cylinder.

[0011] Preferably, slots are provided on both side surfaces above the water inlet, a filter core is movably installed inside the water inlet, and blocks are fixedly connected to both sides of the filter core.

[0012] Preferably, the stirring mechanism includes a first driving motor, which is arranged above the upper cover. The output end of the first driving motor is fixedly connected to a transmission rod, and the outside of the transmission rod is fixedly connected to a stirring blade.

[0013] Preferably, a connecting rod is fixedly connected to an outer side of the transmission rod, and a scraper is fixedly connected to one side of the connecting rod.

[0014] Preferably, the shielding assembly includes a cylinder, and one end of the cylinder is fixedly connected to a baffle.

[0015] Preferably, the baffles are provided in two groups, wherein both sides of the baffles of one group are fixedly connected with docking blocks, and both sides of the baffles of the other group are provided with docking grooves.

[0016] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0017] The utility model can ensure that the extractant is in full contact with the pollutants in the wastewater by arranging the separation tank, the water inlet, the stirring mechanism, the centrifugal drum and the shielding component. Such full contact helps the pollutants to achieve a higher distribution ratio between the extractant and the water, thereby improving the extraction and separation efficiency. The phenolic resin wastewater and the extractant are respectively poured into the centrifugal drum in the separation tank from the water inlet, and the filter holes outside the centrifugal drum are blocked by a baffle driven by an air cylinder to prevent the phenolic resin wastewater and the extractant from overflowing before they are mixed. Then, the first drive motor switch is turned on to drive the transmission rod and the stirring blade to rotate, so that the extractant is in full contact with the phenolic substances in the wastewater and a mass transfer process occurs. Finally, when the mixing is completed, the baffle is retracted by the air cylinder, and then the second drive motor switch is turned on to drive the centrifugal drum to rotate, so that the phenolic resin wastewater and the extractant in the centrifugal drum are centrifugally separated.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides Figures 1-5 A centrifugal separation device for treating phenolic resin wastewater shown includes a separation tank 1;

[0028] The upper cover 2 is installed above the separation tank 1 and is used for disassembly. Bolts 3 are threaded through both sides of the upper cover 2. A water inlet 4 is opened on the upper side of the upper cover 2, and a drain pipe 13 is opened on the lower side of the separation tank 1;

[0029] A stirring mechanism 8 is provided above the upper cover 2 and is used for stirring;

[0030] A centrifugal cylinder 10 is provided inside the separation tank 1 for centrifugal separation. A second drive motor 9 is provided below the separation tank 1. The output end of the second drive motor 9 is fixedly connected to the centrifugal cylinder 10. Filter holes 11 are provided on the outside of the centrifugal cylinder 10.

[0031] The shielding assembly 12 is installed inside the separation tank 1 and is used to block the centrifugal cylinder 10. The phenolic resin wastewater and the extractant are respectively poured into the centrifugal cylinder 10 in the separation tank 1 from the water inlet 4, and the baffle 1202 pushed by the cylinder 1201 is used to block the filter hole 11 outside the centrifugal cylinder 10 to prevent the phenolic resin wastewater and the extractant from overflowing before they are mixed. Then, the first drive motor 801 switch is turned on to drive the transmission rod 802 and the stirring blade 803 to rotate, so that the extractant and the phenolic substances in the wastewater are fully in contact and a mass transfer process occurs. Finally, when the mixing is completed, the baffle 1202 is retracted by the cylinder 1201, and then the second drive motor 9 switch is turned on to drive the centrifugal cylinder 10 to rotate, so that the phenolic resin wastewater and the extractant in the centrifugal cylinder 10 are centrifugally separated.

[0032] like Figure 1 and Figure 2 As shown, slots 5 are provided on both side surfaces above the water inlet 4, a filter element 6 is movably installed inside the water inlet 4, and blocks 7 are fixedly connected to both sides of the filter element 6. By installing the filter element 6 in the water inlet 4, preliminary filtration can be performed before the phenolic resin wastewater is poured in to filter out some large particles of impurities, thereby improving the subsequent separation effect.

[0033] like Figure 1 、 Figure 2 and Figure 3 As shown, the stirring mechanism 8 includes a first drive motor 801, which is arranged above the upper cover 2. The output end of the first drive motor 801 is fixedly connected to a transmission rod 802, and the outside of the transmission rod 802 is fixedly connected to a stirring blade 803. When the phenolic resin wastewater and the extractant are added to the centrifuge cylinder 10 at the same time according to a proportion, by turning on the switch of the first drive motor 801, the transmission rod 802 and the stirring blade 803 are driven to rotate, thereby improving the mass transfer process of the phenolic resin wastewater and the extractant.

[0034] like Figure 3 As shown, a connecting rod 804 is fixedly connected to one side of the outer side of the transmission rod 802, and a scraper 805 is fixedly connected to one side of the connecting rod 804. When the transmission rod 802 and the stirring blade 803 rotate to mix the phenolic resin wastewater and the extractant, in order to avoid the subsequent rotation of the centrifugal barrel 10 causing the filter holes 11 to be blocked, the transmission rod 802 rotates and drives the connecting rod 804 and the scraper 805 on one side to stick to the inner wall of the centrifugal barrel 10, thereby avoiding clogging of the filter holes 11 in the centrifugal barrel 10.

[0035] like Figure 1 andFigure 5 As shown, the shielding assembly 12 includes a cylinder 1201, and one end of the cylinder 1201 is fixedly connected to a baffle 1202. When the phenolic resin wastewater in the centrifugal barrel 10 is mixed with the extractant, the internal wastewater is prevented from flowing out of the filter holes 11 in the centrifugal barrel 10. By turning on the switch of the cylinder 1201, the baffle 1202 is pushed to shield the multiple filter holes 11 outside the centrifugal barrel 10, thereby preventing the wastewater from leaking out and affecting the stirring and mixing effect.

[0036] like Figure 5 As shown, there are two groups of baffles 1202, one group of baffles 1202 has docking blocks 1203 fixedly connected on both sides, and the other group of baffles 1202 has docking grooves 1204 on both sides. When the baffles 1202 are pushed by the cylinder 1201, the docking blocks 1203 on both sides of one group of baffles 1202 are inserted into the docking grooves 1204 on both sides of the other group of baffles 1202, so as to facilitate the docking and merging of the two.

[0037] The working principle of the utility model is as follows: first, the external power supply is turned on, and then the phenolic resin wastewater is poured into the separation tank 1 from the water inlet 4 on one side of the upper cover 2, and the filter element 6 in the water inlet 4 can preliminarily filter the impurities in the wastewater in advance. When the filtered phenolic resin wastewater enters the centrifugal cylinder 10, a certain proportion of extractant is then added and enters the centrifugal cylinder 10 from the water inlet 4, and then the first drive motor 801 switch is turned on to drive the transmission rod 802 and the stirring blade 803 to rotate, so that the phenolic resin wastewater and the extractant are quickly mixed and dispersed, so that the extractant and the phenolic substances in the wastewater are fully in contact and a mass transfer process occurs. At the same time, the transmission rod 802 drives the external connecting rod 804 and the scraper 805 to rotate closely against the inner wall of the centrifugal cylinder 10 during the rotation process to avoid clogging of the filter holes 11 in the centrifugal cylinder 10. When the stirring and mixing is completed , turn off the first drive motor 801 switch, then the cylinder 1201 switches on both sides of the separation tank 1, pull the two sets of baffles 1202 apart from each other, so that the baffles 1202 are separated from the outside of the centrifuge cylinder 10, then turn on the second drive motor 9 switch to drive the centrifuge cylinder 10 to rotate. Under the action of centrifugal force, phenolic substances are extracted into the extractant to form an organic phase, and the wastewater forms an aqueous phase, completing the two-phase separation process. The separated wastewater enters the separation tank 1 and is discharged through the drain pipe 13 below. The organic phase in the centrifuge cylinder 10 can be taken out by threading the upper cover 2 and the separation tank 1 after the separation is completed. Finally, after the separation is completed, turn off the second drive motor 9 switch, and finally cut off the external power supply. In this way, the use process of the centrifugal separation device for phenolic resin wastewater treatment is completed.

[0038] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
