Description

Technical Field

[0001] The utility model relates to the technical field of pepper processing, and particularly relates to a soaking pepper wastewater treatment device. Background Art

[0002] In the current pepper soaking wastewater treatment system, targeted treatment of impurities is achieved through the strategy of layered extraction and separate treatment of wastewater at different height layers. Specifically, the system relies on precise control of water pumps and valves to sequentially extract wastewater from the bottom, middle, and top of the soaking pool and separately transport it to different treatment pools for treatment.

[0003] However, in the actual wastewater treatment process, denser particulate matters, easily aggregated colloids, and some organic substances will quickly settle to the bottom when the wastewater is static or the flow rate slows down, forming an impenetrable sediment layer. When extracting the wastewater at the lowest layer, due to the barrier of the sediment layer, the extracted liquid may be mixed with the upper-layer wastewater, resulting in mixed water quality and greatly reducing the effect of layered treatment. Summary of the Utility Model

[0004] The purpose of the utility model is to address the phenomenon of impurity sedimentation and accumulation in wastewater and improve the accuracy and efficiency of layered treatment, and a soaking pepper wastewater treatment device is proposed.

Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0040] Combined with Figures 1 - 5 As shown, a soaking pepper wastewater treatment device of the present utility model includes a support 1 provided on the ground and a soaking pool 2 for soaking pepper, wherein the support 1 is provided outside the soaking pool 2, and further includes:

[0041] Support frames 3, two in number, are fixedly installed inside the soaking pool 2, and the two support frames 3 are arranged parallel to each other;

[0042] Fixing frame 4, which is arranged between the two support frames 3, and its number and distribution position are adapted to those of the support frames 3;

[0043] Filter screen assembly 5, which is arranged on the fixing frame 4 and is used to block and separate impurities at different levels in the soaking pool 2 to prevent impurities at different levels from sinking to the bottom and accumulating;

[0044] Water outlet pipeline 6, which is arranged on the soaking pool 2 and is used to extract waste water at different levels for targeted treatment.

[0045] The overall device is supported by a bracket 1 set on the ground. The bracket 1 is stably located outside the soaking pool 2, providing a stable support foundation for the entire treatment device. The soaking pool 2, as the main place for pepper soaking, contains the wastewater and pepper raw materials to be treated inside. In order to effectively deal with the problem of impurities sinking to the bottom and accumulating in the wastewater, two parallel support frames 3 are fixedly installed inside the soaking pool 2. These two support frames 3 not only provide an installation foundation for subsequent components, but also ensure the stability and symmetry of the device structure through their parallel arrangement. Between the support frames 3, a fixing frame 4 is correspondingly set according to the number and distribution position of the support frames 3. The design of the fixing frame 4 enables it to closely fit the support frames 3, forming a stable support structure. This structure provides a reliable support platform for the installation of the filter screen assembly 5. As one of the core components of the device, the filter screen assembly 5 is set on the fixing frame 4. Through its fine mesh structure, the filter screen assembly 5 can effectively intercept and separate impurities at different levels in the soaking pool 2. These impurities include, but are not limited to, particulate matters with a relatively large density, colloids prone to aggregation, and some organic substances. Under the natural flow of the wastewater, the impurities are intercepted by the filter screen assembly 5 at their respective corresponding levels, thus avoiding their sinking to the bottom and accumulating due to gravity and keeping the layering of the wastewater clear. Finally, in order to achieve targeted treatment of wastewater at different levels, a water outlet pipeline 6 is set on the soaking pool 2. The water outlet pipeline 6 precisely extracts wastewater at different levels in the soaking pool 2, reducing cross-contamination between wastewater at different levels, thereby improving the accuracy and efficiency of layered treatment. In summary, through the coordinated work of the support frames 3, the fixing frame 4, the filter screen assembly 5, and the water outlet pipeline 6, this pepper soaking wastewater treatment device realizes the effective interception and layered treatment of impurities in pepper soaking wastewater, improving the efficiency and effect of wastewater treatment. The specific operation process of the layered treatment of pepper soaking wastewater has been disclosed in Chinese Patent CN213356990U, and the specific working principle will not be elaborated again.

[0046] In a preferred embodiment of the present utility model, it can be further configured as follows: As Figure 4 , Figure 5As shown in the figure; a vertically arranged slide rail groove is machined on the side surface of the support frame 3, and a sliding member adapted to the slide rail groove is fixedly installed on the fixed frame 4. The fixed frame 4 vertically slides on the surface of the support frame 3 through the sliding member and the slide rail groove. In order to achieve the vertical sliding displacement of the fixed frame 4 on the support frame 3, a sliding member adapted to the slide rail groove is fixedly installed on the fixed frame 4. These sliding members are not directly marked in the figure, but can be understood as being fixed on the fixed frame 4, and the components used in cooperation with the slide rail groove are precisely embedded in the slide rail groove, ensuring the smoothness and accuracy of the fixed frame 4 during the sliding process. When it is necessary to adjust the position of the fixed frame 4, drive the sliding member to slide up and down in the slide rail groove. As the sliding member moves, the fixed frame 4 and the filter screen assembly 5 installed thereon will also correspondingly achieve vertical sliding displacement on the surface of the support frame 3.

[0047] In a preferred embodiment of the present invention, it can be further configured as: as Figure 2 , Figure 4 shown; the filter screen assembly 5 includes:

[0048] A bottom polyester fiber mesh 51, arranged between two fixed frames 4, which is perpendicular to the fixed frames 4. The bottom polyester fiber mesh 51 is used to intercept heavy organic matter to prevent it from depositing on the bottom of the pool;

[0049] A middle microporous filter screen 52, arranged between two fixed frames 4, which is perpendicular to the fixed frames 4. The middle microporous filter screen 52 intercepts suspended solids and colloidal substances to prevent them from depositing on the bottom of the pool; and

[0050] The top fine stainless steel mesh 53 is arranged between two fixing frames 4 and is perpendicular to the fixing frames 4. The top fine stainless steel mesh 53 is used to intercept suspended solids to prevent them from depositing on the bottom of the pool. The middle microporous filter screen 52 is located between the bottom polyester fiber mesh 51 and the top fine stainless steel mesh 53.The filter screen assembly 5, as a key part of the soaked pepper wastewater treatment device, is designed to effectively intercept and separate different impurities in the wastewater through multi-layer filtration. This assembly includes a bottom polyester fiber screen 51, a middle microporous filter screen 52, and a top fine stainless steel screen 53. They are all arranged between two fixed frames 4 and are perpendicular to the fixed frames 4. The bottom polyester fiber screen 51 is installed at a lower position in the soaking pool 2. It selects a filter screen material with a smaller pore size and higher strength to ensure that it can effectively intercept heavy organic matter. Under the natural flow of the wastewater, these impurities will be blocked by the bottom polyester fiber screen 51, preventing them from depositing on the bottom of the pool. This design reduces the accumulation of bottom impurities, keeps the bottom of the pool clean, and provides a better working environment for subsequent treatment processes. The middle microporous filter screen 52 is located above the bottom polyester fiber screen 51 and is also perpendicular to the fixed frame 4. It selects a filter screen material with a moderate pore size to further intercept suspended solids and colloidal substances in the wastewater. The top fine stainless steel screen 53 is installed at the top of the filter screen assembly 5. It selects a filter screen material with a slightly larger pore size to intercept suspended solids. In summary, the filter screen assembly 5 realizes the comprehensive interception and layered treatment of impurities in the soaked pepper wastewater through the bottom polyester fiber screen 51, the middle microporous filter screen 52, and the top fine stainless steel screen 53. This design not only improves the efficiency and effect of wastewater treatment but also ensures the stability and reliability of the effluent quality. It should also be noted that: During the soaking process, pepper is mainly placed in a soaking basket with holes and is placed at the center of the soaking pool 2. Therefore, most of the impurities during soaking are located in the central position of the soaking pool 2. So, the size of the filter screen assembly 5 only needs to cover the center of the soaking pool 2. There is a certain gap between the edge of the filter screen assembly 5 and the inner wall of the soaking pool 2. This gap will not affect the effect of intercepting impurities in the soaked pepper wastewater and the final layered treatment. At the same time, the suspended solids generated during the soaking process of pepper can be effectively intercepted by the top fine stainless steel screen 53. The suspended solids and colloidal substances can pass through the top fine stainless steel screen 53 and be intercepted by the middle microporous filter screen 52. Finally, the generated heavy organic matter can pass through the middle microporous filter screen 52 and be intercepted by the bottom polyester fiber screen 51, preventing it from depositing on the bottom of the pool, thus enabling layered operation during the process of pumping wastewater treatment, effectively avoiding water quality mixing and affecting subsequent layered treatment. During the subsequent treatment of the soaked pepper wastewater, when pumping wastewater at different levels, due to the existence of pumping suction, most of the impurities on the filter screen assembly 5 will also be pumped away, so as to carry out targeted operations. A small part of the impurities will remain on the filter screen assembly 5 and will be treated specifically when cleaning the filter screen assembly 5.

[0051] In a preferred embodiment of the present utility model, it can be further configured as: As Figure 4 , Figure 5As shown in the figure; three sets of sliding tracks are fixedly installed on the surface of the fixing frame 4. Sliding parts adapted to the sliding tracks are fixedly installed on the surfaces of the bottom polyester fiber mesh 51, the middle microporous filter mesh 52, and the top fine stainless steel mesh 53. Among them, the bottom polyester fiber mesh 51, the middle microporous filter mesh 52, and the top fine stainless steel mesh 53 are detachably connected to the fixing frame 4 through the sliding tracks and the sliding parts, so as to realize the disassembly and cleaning of the bottom polyester fiber mesh 51, the middle microporous filter mesh 52, and the top fine stainless steel mesh 53. Three sets of sliding tracks are fixedly installed on the surface of the fixing frame 4. These sliding tracks not only provide a stable installation basis for the filter assembly 5, but also realize the flexibility of their disassembly. The bottom polyester fiber mesh 51, the middle microporous filter mesh 52, and the top fine stainless steel mesh 53, as important components of the filter assembly 5, are fixedly installed with sliding parts adapted to the sliding tracks on their surfaces. These sliding parts are exquisitely designed and can slide smoothly on the sliding tracks while ensuring the stability of the filter layer during operation. When it is necessary to clean or replace the filter assembly 5, the operator can easily detach the bottom polyester fiber mesh 51, the middle microporous filter mesh 52, and the top fine stainless steel mesh 53 from the fixing frame 4 through the sliding parts. This process does not require complex tools or cumbersome steps, greatly improving the convenience of maintenance. The disassembled filter layers can be cleaned separately to remove the attached impurities and dirt and restore their filtering performance. After cleaning, the operator can also reinstall the filter layers on the fixing frame 4 through the sliding parts to ensure their tight fit with the sliding tracks. This detachable connection design not only facilitates the cleaning and maintenance of the filter, but also extends the service life of the filter assembly 5 and reduces the performance degradation and replacement cost caused by long-term use.

[0052] In a preferred embodiment of the present utility model, it can be further configured as follows: As Figure 2 shown in the figure; a sensor assembly 7 for real-time monitoring of wastewater parameters at different height levels in the soaking pool 2 is further provided on the bracket 1 to clean the filter assembly 5 in a timely manner when necessary and maintain the filtering efficiency of the filter. At the same time, the presence of the filter also reduces the accumulation of impurities in the soaking pool and avoids the occurrence of sedimentation and accumulation at the bottom. Among them, the sensor assembly 7 includes:

[0053] A turbidity sensor 71, fixedly installed on the support frame 3, which is located below the bottom polyester fiber mesh 51;

[0054] An on-line COD monitor 72, fixedly installed on the support frame 3, which is located between the middle microporous filter mesh 52 and the bottom polyester fiber mesh 51; and

[0055] The dissolved oxygen sensor 73 is fixedly installed on the support frame 3, which is located between the middle microporous filter screen 52 and the top fine stainless steel mesh 53. The support 1 serves as the basic support structure of the entire wastewater treatment device. It not only bears the soaking pool 2 and the filter screen assembly 5, but also is provided with a sensor assembly 7, which is composed of multiple professional sensors and is respectively installed at different height positions on the support frame 3 to achieve comprehensive monitoring of the wastewater parameters in the soaking pool 2. The turbidity sensor 71 is fixedly installed on the support frame 3, and its position is selected below the bottom polyester fiber mesh 51. This layout enables the turbidity sensor 71 to directly monitor the turbidity of the wastewater. Through real-time monitoring, the interception effect of the bottom polyester fiber mesh 51 can be accurately judged. Once turbidity anomalies are found, measures can be taken in a timely manner to clean the filter screen, thereby maintaining its interception effect. Secondly, the on-line COD monitor 72 is also fixedly installed on the support frame 3, but its position is between the middle microporous filter screen 52 and the bottom polyester fiber mesh 51. The on-line COD monitor 72 is responsible for monitoring the change of chemical oxygen demand in the wastewater, which is an important indicator for evaluating the organic pollution degree of the wastewater. By monitoring the COD value of this layer of wastewater, the interception effect of the middle microporous filter screen 52 on organic matter can be understood, and it can be judged whether the filter screen needs to be maintained or replaced accordingly. Finally, the dissolved oxygen sensor 73 is fixedly installed on the support frame 3 and is located between the middle microporous filter screen 52 and the top fine stainless steel mesh 53. It can monitor the interception effect of the top fine stainless steel mesh 53. At the same time, dissolved oxygen is an important water quality parameter in the wastewater treatment process, which directly affects the effect of the subsequent biological treatment process and provides data support for the subsequent wastewater treatment process to select different treatment means according to the actual situation. For example, when the dissolved oxygen is abnormal, corresponding wastewater treatment reagents are added to facilitate subsequent treatment.

[0056] In a preferred embodiment of the present utility model, it can be further configured as follows: as Figure 2 、 Figure 3 shown; a vertical lifting assembly 8 is provided on the support 1. The vertical lifting assembly 8 is used to take out the filter screen assembly 5 from the soaking pool 2 when cleaning the filter screen assembly 5. The vertical lifting assembly 8 includes:

[0057] A winch 81, fixedly installed on the support 1, and a steel wire rope 82 is arranged at its retracting and releasing end. One end of the steel wire rope 82 far from the winch 81 is fixedly connected to the support frame 3; and

[0058] The guide wheel 83 is arranged on the bracket 1. The steel wire rope 82 is in contact with the outer side of the guide wheel 83. The bracket 1 serves as the main structure of the entire wastewater treatment device. It not only bears the soaking pool 2 and the filter screen assembly 5, but also integrates the vertical lifting assembly 8. The vertical lifting assembly 8 mainly consists of a winch 81, a steel wire rope 82 and a guide wheel 83. The winch 81 is fixedly installed at an appropriate position on the bracket 1. As the power source, it is responsible for the retraction and release operation of the steel wire rope 82. One end of the steel wire rope 82 is tightly connected to the retraction and release end of the winch 81, and the other end is cleverly fixedly connected to the support frame 3. This connection method ensures that when the winch 81 works, the support frame 3 and the filter screen assembly 5 thereon can be lifted or lowered together through the steel wire rope 82. To ensure the stability and directionality of the steel wire rope 82 during the retraction and release process, a guide wheel 83 is also arranged on the bracket 1. The position of the guide wheel 83 is carefully arranged so that when the steel wire rope 82 is in contact with its outer side, it can slide smoothly along a predetermined path. This not only reduces the frictional loss between the steel wire rope 82 and the bracket 1, but also improves the smoothness and reliability of the entire lifting process. When it is necessary to clean the filter screen assembly 5, the operator only needs to start the winch 81 to make it work. As the winch 81 rotates, the steel wire rope 82 is gradually tightened, thereby driving the support frame 3 and the filter screen assembly 5 thereon to rise slowly. Under the guidance of the guide wheel 83, the filter screen assembly 5 can smoothly leave the water surface of the soaking pool 2 until it is completely lifted above the bracket 1. At this time, the operator can conveniently clean and maintain the filter screen assembly 5. After the cleaning is completed, by operating the winch 81 in the reverse direction, the filter screen assembly 5 can be placed back into the soaking pool 2 again.

[0059] In a preferred embodiment of the present utility model, it can be further configured as follows: as Figure 1 shown; the water outlet pipeline 6 includes:

[0060] Branch pipelines 61, three in number, are fixedly installed on the outer wall of the soaking pool 2 and are in communication with the soaking pool 2;

[0061] Electric valves 62 are arranged on the outer sides of the branch pipelines 61, and their number and distribution positions are adapted to the branch pipelines 61; and

[0062] The main pipeline 63 is fixedly installed on the outer wall of the soaking pool 2. One end of the branch pipeline 61 away from the soaking pool 2 is communicated with the main pipeline 63. The water outlet pipeline 6, as a key part of the wastewater discharge of the soaking pool 2, includes three branch pipelines 61, all of which are fixedly installed on the outer wall of the soaking pool 2 and are communicated with the inside of the soaking pool 2. This multi-branch pipeline design enables wastewater to be pumped out from different positions of the soaking pool 2, which helps with stratified discharge treatment. On the outside of each branch pipeline 61, an electric valve 62 is provided, which is adapted to the quantity and distribution position thereof. As a control element, the opening and closing state of the electric valve 62 directly determines the on-off of the corresponding branch pipeline 61. Through remote control or a preset program, the operator can conveniently control the opening and closing of the electric valve 62, thereby realizing the flow control of the branch pipeline 61. Finally, one end of all the branch pipelines 61 away from the soaking pool 2 is communicated with a common main pipeline 63. As a summary channel for wastewater discharge, the main pipeline 63 uniformly discharges the wastewater after extracting wastewater at different levels for subsequent treatment.

[0063] In a preferred embodiment of the present utility model, it can be further configured as follows: as Figure 1 、 Figure 2 shown; an impurity discharge pipeline 9 is fixedly installed at the bottom of the soaking pool 2. The impurity discharge pipeline 9 is communicated with the soaking pool 2. A discharge valve 10 is provided on the impurity discharge pipeline 9. As an important part in the process of wastewater treatment, a certain amount of impurities, such as particulate matters and suspended matters, will inevitably accumulate inside the soaking pool 2. In order to keep the soaking pool 2 clean and the wastewater treatment effect, an impurity discharge pipeline 9 is fixedly installed particularly below the filter screen assembly 5, that is, at the bottom of the soaking pool 2. This pipeline is directly connected to the inside of the soaking pool 2, forming an effective impurity discharge channel. A discharge valve 10 is provided on the impurity discharge pipeline 9. As a control element, the opening and closing state of this valve determines the on-off of the impurity discharge pipeline 9. Under normal circumstances, the discharge valve 10 is in a closed state to prevent wastewater or impurities from being directly discharged without treatment. However, when a certain amount of impurities accumulates at the bottom of the soaking pool 2 and needs to be cleaned, the operator can open the discharge valve 10 to connect the impurity discharge pipeline 9 with the inside of the soaking pool 2. As the discharge valve 10 is opened, the impurities at the bottom of the soaking pool 2 will gradually be discharged along the impurity discharge pipeline 9 under the action of gravity. This process not only helps to reduce the accumulation of impurities in the soaking pool 2 and avoid its negative impact on the wastewater treatment effect.

[0064] The specific working principle of a soaking pepper wastewater treatment device of the present utility model is as follows:

[0065] Peppers are put into the soaking pool 2, and the pepper skins are washed off through the soaking process. During this process, all the peppers and the corresponding pepper skins are located above the top fine stainless steel mesh 53;

[0066] The filter assembly 5 can effectively block and separate different levels of impurities in the soaking tank 2 through its fine mesh structure. These impurities include but are not limited to high-density particulate matter, easily aggregated colloids and some organic matter. The bottom polyester fiber mesh 51 is mainly used to intercept heavy organic matter, the middle microporous filter 52 further intercepts suspended solids and colloids, and the top fine stainless steel mesh 53 intercepts suspended solids. This design ensures that different levels of impurities in the soaking tank 2 can be accurately blocked and separated to avoid the situation that when the wastewater at the lowest level is extracted, the extracted liquid may be mixed with the upper wastewater due to the obstruction of the sediment layer, resulting in mixed water quality and greatly reduced stratified treatment effect;

[0067] In conjunction with the use of the water outlet pipe 6, by controlling the opening and closing of the electric valve 62, wastewater at different levels can be selectively extracted for targeted treatment, and the extracted wastewater is discharged through the main pipe 63 and enters the subsequent treatment process;

[0068] In order to monitor the parameters of wastewater at different heights in the soaking tank 2 in real time, a sensor assembly 7 is also provided on the bracket 1, and the assembly includes a turbidity sensor 71, an online COD monitor 72 and a dissolved oxygen sensor 73, which are respectively installed on the support frame 3 and located between different levels of the filter assembly 5. These sensors can monitor key parameters such as turbidity, COD value and dissolved oxygen content of the wastewater in real time, and provide data support for the cleaning and maintenance of the filter assembly 5;

[0069] When the filter assembly 5 needs to be cleaned, the vertical lifting assembly 8 can be started. The assembly consists of a winch 81, a wire rope 82 and a guide wheel 83. The winch 81 is connected to the support frame 3 through the wire rope 82. When the winch 81 is working, the wire rope 82 drives the support frame 3 and the filter assembly 5 thereon to rise together, and is guided by the guide wheel 83 to achieve a smooth lifting. At this time, the operator can disassemble and clean the filter assembly 5, and after the cleaning is completed, the winch 81 can be reversed to put it back to its original position;

[0070] Finally, in order to discharge impurities at the bottom of the soaking tank 2, an impurity discharge pipeline 9 is fixedly installed at the bottom, the pipeline is connected to the inside of the soaking tank 2, and is provided with a discharge valve 10. When it is necessary to discharge impurities, it is only necessary to open the discharge valve 10, and the impurities will be discharged through the pipeline under the action of gravity;

[0071] In summary, the present pepper soaking wastewater treatment device achieves efficient treatment of pepper wastewater through layered filtration of the filter assembly 5, flexible extraction of the outlet pipe 6, real-time monitoring of the sensor assembly 7, and the auxiliary effects of the vertical pulling assembly 8 and the impurity discharge pipe 9.
