Description

Technical Field

[0001] This utility model relates to the field of semi-coke production technology, specifically to a coal gas condensate recovery device in the semi-coke production process. Background Technology

[0002] The coal gas condensate produced during the semi-coke production process is referred to as semi-coke wastewater. The semi-coke wastewater is generated because the moisture contained in the coal volatilizes out of the pyrolysis furnace along with the coal gas during the semi-coke production process. In the subsequent purification process of raw coal gas, when the condensate is used to cool the raw coal gas, water, tar, and dust entrained in the raw coal gas will enter the condensate. In order to reduce costs and increase utilization rate, it is necessary to treat and recycle the coal gas condensate, i.e., semi-coke wastewater.

[0003] A search revealed a Chinese patent document disclosing a floating oil recovery structure for a semi-coke wastewater purification device (application number: CN202420362319.8). This floating oil recovery structure for a semi-coke wastewater purification device includes a base plate and a shell. A filter cylinder is installed inside the shell, and multiple evenly distributed filter holes are formed on the outer wall of the filter cylinder. A filtrate chamber is formed between the filter cylinder and the shell. A rotating shaft is rotatably connected between the left and right end faces inside the shell. A spiral blade is fixedly connected to the outer wall of the rotating shaft, and multiple connecting rods are fixedly connected to the outer wall of the rotating shaft. Each of the multiple connecting rods has a brush fixedly connected to its outer wall, and each of the multiple brushes abuts against the inner wall of the filter cylinder.

[0004] The structure disclosed in this patent can discharge flocculents and clean the filter cartridge through the rotation of spiral blades and brushes. However, while the brush is more effective at cleaning the filter cartridge, flocculents tend to accumulate on the brush surface after prolonged use, which can affect the brush's effectiveness in subsequent cleaning operations. In addition, the outlet position in this structure is relatively fixed, and when workers inject wastewater and flocculant into the structure, the wastewater and flocculant have a limited residence time in the structure. Therefore, the flocculant's effect on wastewater treatment is easily affected, which in turn affects the recycling of treated wastewater. Utility Model Content

The internal part of the support plate 11 is equipped with a positioning mechanism 12. The surface of the support plate 2 is provided with a slot. The positioning frame 13 is detachably connected inside the slot. The positioning frame 13 and the positioning mechanism 12 are used to limit the drainage mechanism 6. The surface of the threaded cylinder 8 is threadedly connected with a rotating cylinder 14. The top of the rotating cylinder 14 is fixedly connected with a feeding pipe 15. The top of the feeding pipe 15 is provided with a storage slot. The storage slot is equipped with an auxiliary mechanism 16. The surface of the rotating cylinder 14 is detachably connected with a filtering mechanism 17. The top of the filtering mechanism 17 is provided with a through slot 18. The top of the bottom plate 1 is fixedly connected with a reinforcing plate 19. Both sides of the top of the reinforcing plate 19 are fixedly connected with arc-shaped plates 20. The inner surface of the arc-shaped plates 20 is in contact with the surface of the rotating cylinder 14. The setting of the arc-shaped plates 20 can increase the stability of the rotating cylinder 14.

[0027] The drive mechanism 5 includes a motor 51, a drive shaft 52, and an auger blade 53. The motor 51 is fixedly connected to the surface of the fixed cylinder 3. The drive shaft 52 rotates through the surface of the fixed cylinder 3. One end of the drive shaft 52 is fixedly connected to the output shaft of the motor 51. The auger blade 53 is fixedly sleeved on the surface of the drive shaft 52. When the operator starts the motor 51, the drive shaft 52 and the auger blade 53 can be driven to rotate. During the rotation, the auger blade 53 can push the flocculants in the wastewater upward so that the flocculants can be discharged from one end of the rotating cylinder 14 and the filter cylinder 171.

[0028] The drainage mechanism 6 includes a hollow ring 61, retaining rings 62, and a drain pipe 63. The surface of the hollow ring 61 is in contact with the surfaces of the fixed cylinder 3 and the fixed ring 7. There are two retaining rings 62, which are fixedly connected to the surfaces on both sides of the hollow ring 61. The drain pipe 63 is fixedly inserted through the surface of the hollow ring 61. The surface of the retaining rings 62 is in contact with the inner wall of the groove. When the operator rotates the drain pipe 63, the hollow ring 61 will rotate. The operator can then restrict the position of the drain pipe 63 using the positioning frame 13. When discharging treated wastewater, the operator can adjust the drain pipe 63 to... Figure 1 The state shown is such that the drain pipe 63 can discharge wastewater. During this process, the retaining ring 62 can increase the stability of the position of the hollow ring 61 and the drain pipe 63. More preferably, the operator can use a filler ring to reinforce and seal the connection between the hollow ring 61, the fixed cylinder 3 and the fixed ring 7.

[0029] The positioning mechanism 12 includes a movable plate 121, a positioning rod 122, and a first compression spring 123. The surface of the movable plate 121 is slidably connected to the inner wall of the outer shell 11. The positioning rod 122 is fixedly connected to the surface of the movable plate 121 and slides through the surfaces of the outer shell 11 and the positioning frame 13. The first compression spring 123 is disposed inside the outer shell 11. The two ends of the first compression spring 123 are fixedly connected to the inner wall of the outer shell 11 and the surface of the movable plate 121, respectively. Under the action of the elastic force of the first compression spring 123, the movable plate 121 drives the positioning rod 122 to move. The positioning rod 122 and the positioning frame 13 work together to limit the position of the positioning frame 13 so that the positioning frame 13 can limit the position of the drain pipe 63.

[0030] The auxiliary mechanism 16 includes a smooth rod 161, a pressure ring 162, a second compression spring 163, and an auxiliary tube 164. The surface of the smooth rod 161 is slidably connected to the inner wall of the storage groove. The pressure ring 162 is fixedly connected to the top of the smooth rod 161. The auxiliary tube 164 is fixedly connected to the inner wall of the pressure ring 162. The second compression spring 163 is sleeved on the surface of the smooth rod 161. The two ends of the second compression spring 163 are fixedly connected to the bottom of the pressure ring 162 and the top of the feeding tube 15, respectively. The surface of the auxiliary tube 164 is flush with the inner wall of the through groove 18. When the wall contacts the material, the operator can press the pressure ring 162 during the feeding process. At this time, the bottom of the auxiliary pipe 164 passes through the through groove 18. The operator can pass the wastewater generated during the semi-coke production process into the filter mechanism 17 through the auxiliary pipe 164 for filtration. Then, under the action of the second compression spring 163, the pressure ring 162 drives the auxiliary pipe 164 to rise, which can release the cooperation between the auxiliary pipe 164 and the through groove 18. This makes it easier for the operator to disassemble and assemble the filter mechanism 17.

[0031] The filtration mechanism 17 includes a filter cylinder 171, a lead screw 172, and a collar 173. The filter cylinder 171 is detachably connected to the inside of the rotating drum 14. There are several lead screws 172 and collars 173. The lead screw 172 is fixedly connected to the surface of the filter cylinder 171 and slides through the surface of the rotating drum 14. The collar 173 is threaded onto the surface of the lead screw 172. The surface of the collar 173 is in contact with the surface of the rotating drum 14. The operator can fix the position of the filter cylinder 171 by rotating the collar 173 and using the cooperation between the collar 173 and the lead screw 172. A through groove 18 is opened at the top of the filter cylinder 171.

[0032] Working principle: The operator presses the pressure ring 162 to lower the auxiliary pipe 164. After the auxiliary pipe 164 passes through the through groove 18, the operator can then introduce wastewater and flocculant into the filter cylinder 171. At the same time, the operator can start the motor 51, and the drive shaft 52 drives the auger blades 53 to rotate, which mixes the wastewater and flocculant. The auger blades 53 can also push the flocculants in the wastewater upwards to discharge them. During this process, the treated wastewater is filtered through the filter cylinder 171. After filtration, the operator can move the positioning rod 122 by moving the moving plate 121. When the positioning frame 13 is in limiting contact, the operator can remove the positioning frame 13 and rotate the drain pipe 63 to adjust it to the desired position. Figure 1 When the wastewater is in the indicated state, it can be discharged through the drain pipe 63. The staff can connect the drain pipe 63 to the external pipeline and recycle the treated wastewater for later use.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model.
