Description

Technical Field

[0001] This utility model relates to the field of waste acid filtration and recycling technology, specifically a leak-proof temporary storage device. Background Technology

[0002] Waste acid filtration refers to the process of removing solid impurities or precipitates from solutions or liquid waste containing waste acid through filtration, thereby achieving the recovery and purification of waste acid. This process is commonly used in industrial production, especially in the treatment of acidic wastewater generated in industries such as metal processing, electroplating, and chemicals.

[0003] These types of liquid media typically require temporary storage and final treatment in a unified processing facility or facility. This effectively manages waste, reduces environmental impact, and ensures that waste is safely and compliantly disposed of.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. Some containers currently used for temporary storage are prone to leakage due to insufficient sealing. These media have certain corrosive, toxic and flammable properties, which can pose great danger to personnel and storage sites; 2. When extracting the media, it is necessary to mix the solid residue and the media evenly, so a stirring device is required. However, the continuous stirring structure requires the equipment to run continuously, which consumes energy. At the same time, some residue will adhere to the inner wall of the storage equipment, which is inconvenient to clean. Utility Model Content

A feed pipe is provided on the surface of the internal sealing element. A tank cover is provided at the top of the tank body. The tank cover is threaded to the outer wall of the top of the tank body through a threaded groove on its inner wall. One end of the feed pipe passes through the center of the surface of the tank cover. Several grooves are distributed in a ring at the bottom of the internal sealing element. The grooves are located inside the tank body. An external sealing assembly is annularly covered on the outer wall where the tank body and the tank cover are connected.

[0006] The surface of the load-bearing frame is provided with a number of limiting hooks. The limiting hooks are distributed in a ring at the lowest point of the surface of the load-bearing frame by means of tension springs. The limiting hooks are engaged with limiting rings, which are distributed in a ring on the outer wall of the bottom of the tank.

[0007] The feed pipe passes through the inner wall of the opening at one end of the can lid and is threaded with a top airtight plug. An external pipe cover is provided above the top airtight plug and is threaded to the outer wall of the feed pipe opening.

[0008] The external sealing assembly includes a metal ring and a rubber septum. The metal rings are connected by a hinge. One side of the rubber septum is glued to the inner wall of the metal ring, and the other side of the rubber septum is attached to the outer wall at the connection between the tank body and the tank lid. The surface of the metal ring is provided with a circular buckle and a metal block.

[0009] More preferably, the tank body adopts a double-layer structure, and a temperature controller is provided on one side of the outer wall of the tank body. A heating element electrically connected to the temperature controller is provided in the interlayer inside the tank body. A discharge pipe is provided at the bottom of the tank body, and a bottom airtight plug is threaded to the inner wall of the discharge pipe on the outer side of the tank body.

[0010] More preferably, the driven gear forms a transmission structure through the output end of a servo motor passing through the shaft of the driving gear, and the auxiliary transmission gear A and the auxiliary transmission gear B form a transmission structure, and the tank body forms a rotating structure between the driven gear and the auxiliary transmission gear B between the load-bearing frame.

[0011] More preferably, the interior of the tank seal has a cavity that communicates with the bottom of the feed pipe, and the cavity is connected to the top of the groove.

[0012] More preferably, a through hole for connecting the feed pipe is provided at the center of the top of the can lid, and an annular groove for fitting into the bottom of the pipe outer cover is provided on the surface of the through hole.

[0013] More preferably, the metal rings are connected by hinges to form an opening and closing structure, and the metal rings are connected by circular buckles and metal blocks to form a locking structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, the temperature control structure of the tank can reduce the possibility of crystallization of the medium under low temperature conditions, ensuring that the medium is always at the required temperature, which helps to ensure the stability of the medium during temporary storage. At the same time, the meshing transmission structure between two sets of gears enables the tank to rotate smoothly, which can better distribute the load during rotation. This rotating structure can make the internal liquid medium and solid metal particles fully mixed, resulting in more uniform discharge. During normal storage, it can reduce the energy consumption caused by continuous stirring. This rotating structure can make the tank flip and invert, which can effectively reduce the possibility of residue accumulating at the bottom and corners during cleaning, reducing the labor intensity of personnel. The structure of the limiting hook and limiting ring can keep the tank stable and stable between the load-bearing frame when stationary, reducing the possibility of shaking. At the same time, the tension spring plays a tensioning role in the limiting structure.

[0016] In this invention, the internal seals, after being fed through the inlet of the feed pipe, flow into the interior of the tank via grooves through their internal cavities. The diversion and conveying structure of the grooves reduces splashing when the medium falls, and also helps to reduce foam generation. At the same time, the internal seals provide good sealing performance during daily storage. The detachable structure facilitates cleaning for both the seals themselves and the tank. The feed pipe and external sealing components further enhance the sealing performance of the tank, effectively preventing the possibility of medium leakage during subsequent rotation of the tank.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 6This utility model provides a technical solution: a leak-proof temporary storage device, including a load-bearing frame 1. A driving gear 2 and a driven gear 3 are rotatably connected inside one side of the load-bearing frame 1, with the driving gear 2 meshing with the lower part of the driven gear 3. An auxiliary transmission gear A 4 and an auxiliary transmission gear B 5 are rotatably connected inside the other side of the load-bearing frame 1, with the auxiliary transmission gear A 4 meshing with the lower part of the auxiliary transmission gear B 5. A tank 6 is provided between the load-bearing frames 1. The auxiliary transmission gear B 5 and the driven gear 3 are respectively welded to both ends of the outer wall of the tank 6 via shafts passing through their axes. The lower part of the tank 6... A liquid receiving groove 7 is provided. An internal sealing element 8 is provided inside the tank body 6. The internal sealing element 8 is threaded to the inner wall of the top opening of the tank body 6 through a threaded groove on its outer wall. A feed pipe 9 is provided on the surface of the internal sealing element 8. A tank cover 10 is provided on the top of the tank body 6. The tank cover 10 is threaded to the outer wall of the top of the tank body 6 through a threaded groove on its inner wall. One end of the feed pipe 9 passes through the center of the surface of the tank cover 10. Several grooves 11 are distributed in a ring at the bottom of the internal sealing element 8. The grooves 11 are located inside the tank body 6. An external sealing component 12 is annularly covered on the outer wall where the tank body 6 connects to the tank cover 10.

[0026] Several limiting hooks 101 are provided on the surface of the load-bearing frame 1. The limiting hooks 101 are distributed in a ring at the lowest point of the surface of the load-bearing frame 1 via tension springs 102. The limiting hooks 101 are engaged with limiting rings 103, which are distributed in a ring on the outer wall of the bottom of the tank 6.

[0027] The feed pipe 9 passes through the inner wall of the opening at one end of the can cover 10 and is threaded with a top airtight plug 901. An external pipe cover 902 is provided above the top airtight plug 901 and is threaded to the outer wall of the opening of the feed pipe 9.

[0028] The external sealing assembly 12 includes a metal ring 1201 and a rubber septum 1202. The metal rings 1201 are connected by hinges. One side of the rubber septum 1202 is glued to the inner wall of the metal ring 1201, and the other side of the rubber septum 1202 is attached to the outer wall at the connection between the tank body 6 and the tank cover 10. The surface of the metal ring 1201 is provided with a circular buckle 1203 and a metal block 1204.

[0029] In this embodiment, as Figure 1 and Figure 5As shown, the tank 6 adopts a double-layer structure, and a temperature controller 13 is provided on one side of the outer wall of the tank 6. A heating element electrically connected to the temperature controller 13 is provided in the interlayer inside the tank 6. A discharge pipe 601 is provided at the bottom of the tank 6, and a bottom airtight plug 602 is threadedly connected to the inner wall of the discharge pipe 601 on the outer side of the tank 6. During the temporary storage of this type of medium, it is affected by certain environmental factors. If the ambient temperature is too low, its viscosity will increase, thereby reducing its fluidity. In the subsequent discharge process, this will cause problems such as a decrease in discharge speed and unevenness. In addition, some of its internal components may solidify at low temperatures. The solidification or crystallization of the medium can affect subsequent processing. The heating element, a heating tube (model HY0088), is located in the interlayer of the tank 6, which does not directly contact the medium stored inside. This effectively isolates the heat, reduces the contact between the medium and the heating element, and lowers the risk of the medium being contaminated or undergoing a chemical reaction, thereby improving the safety of the system. Furthermore, the temperature inside the tank 6 can be monitored in real time by an external temperature controller 13 (model OHR-E300), and automatically adjusted according to the set temperature range to ensure that the medium is always at the required temperature, which helps to ensure the stability of the medium during temporary storage.

[0030] In this embodiment, as Figure 2 As shown, the driven gear 3 forms a transmission structure through the output end of the servo motor passing through the shaft of the driving gear 2, and the auxiliary transmission gear A 4 and auxiliary transmission gear B 5 form a transmission structure. The tank 6 forms a rotating structure between the driven gear 3 and the auxiliary transmission gear B 5 on the load-bearing frame 1. The rotation of the driving gear 2 drives the driven gear 3 to rotate, thereby realizing the transmission of another set of auxiliary transmission gears A 4 and B 5 under the connection of the tank 6. The meshing transmission structure between the two sets of gears enables the tank 6 to rotate smoothly, which can better share the load during rotation and provide stable and reliable rotational support. When the internal medium needs to be extracted, the rotating structure can be used to fully mix the internal liquid medium and solid metal particles, so that the discharge is more uniform. During normal storage, it can reduce the energy consumption caused by continuous stirring. At the same time, the rotating structure can make the tank 6 flip upside down, which can effectively reduce the possibility of residues accumulating at the bottom and corners during cleaning, reduce the labor intensity of personnel operation, and the thorough cleaning of the tank 6 can reduce the accumulation of residues and dirt, reducing the risk of contamination of the next batch of products.

[0031] In this embodiment, as Figure 5As shown, the internal seal 8 of the tank has a cavity that communicates with the bottom of the feed pipe 9 and is connected to the top of the groove 11. After the feed pipe 9 discharges the material through the inlet of the internal seal 8, it flows into the tank 6 through the groove 11 via its internal cavity. This allows the operator to safely transport waste acid or waste liquid into the tank 6 through the feed pipe 9 without the possibility of splashing or dripping. Furthermore, the labyrinthine structure of the groove 11 disperses the medium when it is discharged from the cavity into the tank 6, making the waste acid or waste liquid flow into the tank 6 more evenly, reducing splashing when the medium falls, and also helping to reduce foam generation. Compared with a tank 6 with a generally large opening, which is more likely to cause the internal medium to evaporate during storage, the internal seal 8 provides good sealing performance. Moreover, its threaded structure makes it detachable, which is beneficial for both itself and the tank 6, making it easier to clean.

[0032] In this embodiment, as Figure 4 and Figure 5 As shown, a through hole for connecting the feed pipe 9 is opened at the axial center of the top of the can lid 10, and an annular groove for fitting into the bottom of the pipe outer cover 902 is opened on the surface of the through hole; the can lid 10 further enhances the sealing structure of the can body 6 based on the internal sealing element 8. The feed pipe 9 passing through the can lid 10 allows the can body 6 to be fed in real time even when the can lid 10 is in a fixed structure. In addition, the sealing structure on both the inner and outer sides of the feed pipe 9 increases the sealing performance inside the feed pipe 9, forming a double sealing protection mechanism. During subsequent rotation and stirring, it can not only prevent leakage of the internal medium, but also reduce the possibility of air entering the interior of the can body 6 through the feed pipe 9 during daily storage, further ensuring the quality and safety of the internal medium storage.

[0033] In this embodiment, as Figure 1 and Figure 3 As shown, the metal rings 1201 are connected by hinges to form an opening and closing structure, and the metal rings 1201 are connected by circular buckles 1203 and metal blocks 1204 to form a locking structure. Because the equipment needs to rotate to achieve the flipping structure of the tank 6 during subsequent discharge to accelerate the full mixing of the internal medium and facilitate extraction, a multi-seal structure is used to prevent the possibility of leakage of the internal medium of the tank 6. The rubber diaphragm 1202 can fill the gap between the tank 6 and the tank cover 10. At the same time, its detachable structure makes it easy for operators to disassemble the external parts and clean the inside of the tank 6.

[0034] The method of use and advantages of this utility model: The working process of this leak-proof temporary storage device is as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, firstly, the external pipe cover 902 is disassembled via a threaded structure, and then the top airtight plug 901 is disassembled via a threaded structure. The external pipe used for conveying the medium is then threadedly connected to the external end of the feed pipe 9. The medium is then conveyed through the external conveying system via the pipe and feed pipe 9 to the cavity of the tank seal 8. Several grooves 11 at the bottom, communicating with the cavity, divert the medium into the interior of the tank body 6. After the medium conveying is completed, the external conveying pipe is disassembled, and the top airtight plug 901 and the external pipe cover 902 are respectively installed on the inner and outer walls of the feed pipe 9 via threaded structures. During daily storage, the tank seal 8 and the external sealing assembly 1... 2. The bottom airtight plug 602 on the surface of the discharge pipe 601 and the structure at the top of the inlet pipe 9 both ensure the sealing of the inside of the tank 6. If a leak occurs on one side of the discharge pipe 601, the medium will flow into the bottom receiving tank 7 through the front end. At the same time, an acid-base sensor (Eutech pH510) is installed in the receiving tank 7. When the medium dripping into the receiving tank 7 comes into contact with the acid-base sensor, the sensor converts it into a corresponding electrical signal. The electrical signal can be transmitted to an external control unit, such as a monitoring system or alarm device. The external control unit can issue a warning based on the received electrical signal to remind the operator to intervene in time. In order to facilitate the unrestricted operation of the tank 6 during subsequent tilting, it is suspended above the load-bearing structure. The structure of the limit hook 101 and limit ring 103 between the frames 1 ensures that the tank 6 remains stable and stable between the load-bearing frames 1 when stationary, reducing the possibility of shaking. Meanwhile, the tension spring 102 plays a tensioning role in the limiting structure. During normal storage, if any medium leaks from the discharge pipe 601, it will drip into the receiving tank 7 and come into contact with the acid / alkali sensor. The sensor converts this into a corresponding electrical signal, which can be transmitted to an external control unit, such as a monitoring system or alarm device. The external control unit can issue a warning based on the received electrical signal, reminding the operator to intervene in time. When the stored medium needs to be extracted, the limit hook 101 is pulled from the limit ring 103. After the surface of 3 is separated, the servo motor makes the driving gear 2 rotate, which in turn makes the driven gear 3 rotate. With the tank body 6 connected, another set of auxiliary transmission gear B 5 and auxiliary transmission gear A 4 generate a transmission structure, which allows the tank body 6 to rotate between the load-bearing frame 1. After accelerating the mixing of the internal medium, after the rotation stops, the bottom airtight plug 602 is removed by thread, and the valve on the surface of the discharge pipe 601 is opened to extract the internal medium through the pipeline and the external centrifugal pump. The circular buckle 1203 and the metal block 1204 are separated to remove the external sealing assembly 12. The tank cover 10 and the inner seal 8 are removed by threaded structure to clean the inner wall of the tank body 6. The internal sewage can be poured out again by the flipping structure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
