Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a biopharmaceutical sewage pretreatment device based on activated carbon adsorption treatment. Background Art

[0002] Biopharmaceutical wastewater is generated during the production process of biopharmaceutical companies, primarily including washing wastewater, fermentation residues, and acid-base wastewater. These wastewaters are characterized by complex composition, toxicity, and high organic content, making them challenging to treat. Given the characteristics of biopharmaceutical wastewater, currently commonly used treatment technologies include physical and chemical methods. Physical methods, including sedimentation, filtration, and adsorption, are primarily used to remove suspended solids and some organic matter from wastewater; chemical methods, including oxidation, reduction, and neutralization, are primarily used to remove toxic substances from wastewater.

[0003] Activated carbon adsorption is widely used in sewage treatment. Its main advantages are high treatment degree and stable effect. Its disadvantage is high treatment cost. Therefore, in the treatment process, activated carbon is always replaced only after long-term multiple uses. However, the effect of activated carbon will gradually deteriorate after multiple uses, and the adsorption effect on sewage treatment will be reduced. Moreover, the sewage treatment equipment needs to be shut down for replacement, which consumes time and cost. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a biopharmaceutical wastewater pretreatment device based on activated carbon adsorption treatment.

[0005] The technical solution of the utility model is: a biopharmaceutical wastewater pretreatment equipment based on activated carbon adsorption treatment, comprising a shell, a filter bin sealed and slidably connected to the inner wall of the shell up and down, a storage tank arranged at the top of the shell, and a recovery tank arranged at the bottom of the shell, wherein activated carbon is contained in the filter bin; at least one recovery mechanism is provided on the shell for recovering the activated carbon into the recovery tank when the filter bin moves downward, and at least one supply mechanism is provided on the shell for supplying the activated carbon in the storage tank to the filter bin when the filter bin moves upward.

[0006] Furthermore, the recovery mechanism includes a spiral tube, a rotating sealing sleeve arranged on the spiral tube and a discharge pipe connected to the recovery tank, the spiral tube and the discharge pipe are both provided with docking holes for rotational docking, the bottom of the filter bin is provided with a threaded through hole that is sleeved with the spiral tube, and the bottom of the filter bin is provided with a first baffle for cooperating with the spiral tube to open or close the threaded through hole, and the first baffle is fixedly connected to the bottom of the filter bin through a first spring.

[0007] Note: When not docked, the spiral tube and the discharge pipe are closed and do not affect the sewage treatment. After the filter chamber is moved down and docked, the spiral tube and the discharge pipe enter the filter chamber and are connected to the recovery tank. When the filter chamber is moved up, the threaded through hole can be automatically closed. The structure is simple and easy to operate, and it can save more energy and cost than electronic control.

[0008] Furthermore, the supply mechanism includes a through hole passing through the bottom of the storage tank, a second baffle for opening or closing the through hole, and a vertically arranged top rod for pushing up the second baffle, the top rod is connected to the shell for sliding up and down through a horizontal rod, the second baffle is fixedly connected to the top of the storage tank through a second spring, and a trigger rod for pushing up the horizontal rod is provided on the side wall of the filter bin.

[0009] Description: The second baffle is lifted by the trigger rod to replenish the activated carbon into the filter chamber. The structure is simple and easy to operate. Compared with electric control, it can save more energy and cost.

[0010] Furthermore, the filter bin is provided with a plurality of vibration mechanisms, which include a roller rotatably arranged on the filter bin, a knocking rod arranged at one end of the roller shaft of the roller and used to knock the filter bin, and a knocking block arranged on the filter bin and cooperating with the knocking rod, and the knocking block is slidably connected to the filter bin through a spring.

[0011] Description: When the filter bin moves upward, the roller drives the knocking rod to rotate multiple times and collide with the knocking block to shift it. When the knocking block is reset, it collides with the protrusion on the filter bin to generate vibration, which makes it easier to evenly disperse the activated carbon in the filter bin to all parts of the filter bin, thereby improving the adsorption effect.

[0012] Furthermore, the recovery tank is externally connected to an activated carbon regeneration device through a pipeline, and the discharge end of the activated carbon regeneration device is connected to the storage tank through a pipeline.

[0013] Description: The activated carbon regeneration equipment is used to desorb and regenerate the used activated carbon, thereby obtaining new activated carbon and replenishing the storage tank, thus realizing the repeated use of activated carbon.

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

[0015] (1) The biopharmaceutical wastewater pretreatment equipment of the present invention is provided with a recovery mechanism and a supply mechanism, so that during the continuous treatment of wastewater, the activated carbon can be replaced multiple times within the period when the activated carbon exerts its efficient adsorption effect, thereby avoiding a significant weakening of the effect of the activated carbon after multiple adsorptions, thereby improving the adsorption effect of the activated carbon on wastewater.

[0016] (2) The biopharmaceutical wastewater pretreatment equipment of the present invention can ensure that there is always activated carbon in the filter chamber to play an adsorption role at each stage by partially replacing the activated carbon instead of completely replacing it each time. Compared with complete replacement, it solves the problem of no activated carbon adsorption in the filter chamber or downtime consuming time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention will be described in further detail below in conjunction with specific implementation methods to better reflect the advantages of the present invention.

[0027] Example 1

[0028] A biopharmaceutical wastewater pretreatment device based on activated carbon adsorption treatment, such as Figure 1 and Figure 2 As shown, it includes a housing 1, a filter chamber 13 that is slidably and sealedly connected to the inner wall of the housing 1, a storage tank 3 arranged on the top of the housing 1, and a recovery tank 2 arranged on the bottom of the housing 1. The side wall of the housing 1 is provided with a water inlet pipe 11 and a water outlet pipe 12. The filter chamber 13 is filled with activated carbon. The power source for the upward and downward sliding of the filter chamber 13 adopts a commercially available telescopic motor.

[0029] like Figure 2 As shown, the housing 1 is provided with a recovery mechanism for recovering half of the activated carbon into the recovery tank 2 when the filter bin 13 moves downward, the recovery mechanism includes a touch sensor, a controller, and a switch for opening or closing the connection between the filter bin 13 and the recovery tank 2, and the touch sensor and the switch are electrically connected to the controller, and the housing 1 is provided with a supply mechanism for supplying half of the activated carbon in the storage tank 3 to the filter bin 13 when the filter bin 13 moves upward, the supply mechanism includes a touch sensor, a controller, and a switch for opening or closing the storage tank 3, and the touch sensor and the switch are electrically connected to the controller, and the recovery mechanism and the supply mechanism are both existing technologies; it can be understood that the single replacement amount of activated carbon is not limited to the above-mentioned case, and can be controlled according to the material port size and / or opening and closing time of the supply mechanism and the recovery mechanism;

[0030] like Figure 3 As shown, a filter screen 24 for separating activated carbon and biopharmaceutical wastewater is provided inside the recovery tank 2 , and a drain pipe 25 is provided on the recovery tank 2 .

[0031] The working principle of the above-mentioned biopharmaceutical wastewater pretreatment equipment based on activated carbon adsorption treatment is: the biopharmaceutical wastewater is continuously introduced into the shell 1 from the water inlet pipe 11, the wastewater is filtered through the filter chamber 13, and the impurities carried by the wastewater are adsorbed by the activated carbon and then discharged from the outlet pipe 12, and the pretreatment is completed; during the adsorption process, the filter chamber 13 moves back and forth up and down. When the filter chamber 13 moves down to contact the feed port of the recovery tank 2, the contact sensor controls the switch to open the feed port of the filter chamber 13 and the recovery tank 2 through the controller, and half of the activated carbon inside the filter chamber 13 is recovered into the recovery tank 2, and then the activated carbon and wastewater are separated through the filter screen 24; when the filter chamber 13 moves up to touch the water inlet pipe 11, the touch sensor controls the storage tank 3 to open through the controller and supplies half of the activated carbon to the filter chamber 13.

[0032] Example 2

[0033] like Figure 8 As shown, this embodiment is different from embodiment 1 in that, Figure 4 、 Figure 6 and Figure 7As shown, the recovery mechanism includes a spiral tube 21, a rotary sealing sleeve arranged in the spiral tube 21 and a discharge pipe 22 connected to the recovery tank 2, and the spiral tube 21 and the discharge pipe 22 are both provided with a docking hole 23 for rotational docking. The bottom of the filter chamber 13 is provided with a threaded through hole 132 that is sleeved with the spiral tube 21, and the bottom of the filter chamber 13 is provided with a first baffle 131 for cooperating with the spiral tube 21 to open or close the threaded through hole 132. The first baffle 131 is fixedly connected to the bottom of the filter chamber 13 by a first spring;

[0034] like Figure 5 As shown, the supply mechanism includes a through hole 31 passing through the bottom of the storage tank 3, a second baffle 32 for opening or closing the through hole 31, and a vertically arranged top rod 133 for pushing the second baffle 32 upward. The top rod is connected to the shell 1 for sliding up and down through a horizontal rod, and the second baffle 32 is fixedly connected to the top of the storage tank 3 through a second spring. A trigger rod 134 for pushing up the horizontal rod is provided on the side wall of the filter bin 13.

[0035] The working principle of this embodiment is different from that of Example 1 in that, when the filter bin 13 moves downward, the threaded through hole 132 docks with the screw tube 21, and the screw tube 21 enters the interior of the filter bin 13 on the one hand to move the first baffle 131 upward, and at the same time the screw tube 21 rotates until the docking hole 23 completely enters the filter bin 13, and the screw tube 21 rotates to dock with the docking hole 23 on the discharge pipe 22, and the activated carbon enters the discharge pipe 22; when the filter bin 13 moves upward, the top column 133 gradually pushes open the second baffle 32, so that the activated carbon in the storage tank 3 falls into the filter bin 13 through the through hole 31, thereby realizing the replenishment and replacement of the activated carbon.

[0036] Example 3

[0037] The difference between this embodiment and embodiment 2 is that there are three recovery mechanisms and three supply mechanisms (not shown in the figure).

[0038] The working principle of this embodiment is different from that of embodiment 2 in that multiple recovery mechanisms can prevent the activated carbon from being too dispersed, resulting in too little recovery when it is concentrated in one place in the filter bin 13. Multiple supply mechanisms can make the supply distribution of the activated carbon in the filter bin 13 more uniform, and the adsorption effect is better.

[0039] Example 4

[0040] The difference between this embodiment and embodiment 2 is that a plurality of vibration mechanisms are provided on the filter bin 13, and the vibration mechanism includes a roller rotatably provided on the filter bin 13, a knocking rod provided at one end of the roller shaft of the roller and used to knock the filter bin, and a knocking block provided on the filter bin 13 and cooperating with the knocking rod, and the knocking block is slidably connected to the filter bin 13 through a spring (not shown in the figure).

[0041] The working principle of this embodiment is different from that of Example 2 in that when the filter bin 13 moves up and down, the roller rubs against the inner wall of the shell 1 and rotates, and the knocking rod collides with the knocking block to generate a vibration during the rotation of the roller, and the knocking rod pushes the knocking block to slide, and the knocking block collides with the protrusion on the filter bin after resetting to generate another vibration, vibrating the activated carbon in the filter bin 13 until it is evenly dispersed, thereby improving the adsorption effect.

[0042] Example 5

[0043] This embodiment is different from embodiment 1 in that Figure 8 As shown, the recovery tank 2 is externally connected to an activated carbon regeneration device 4 through a pipeline, and the discharge end of the activated carbon regeneration device 4 is connected to the storage tank 3 through a pipeline. The activated carbon regeneration device is a commercially available device.

[0044] The working principle of this embodiment is different from that of embodiment 1 in that the activated carbon regeneration device 4 is used to desorb and regenerate the used activated carbon, thereby obtaining new activated carbon and replenishing the storage tank 3, thereby realizing the repeated recycling of the activated carbon.
