Description

Technical Field

[0001] The utility model relates to the technical field of sludge dehydration pretreatment, in particular to a pretreatment device for dehydrating residual sludge in winemaking. Background Art

[0002] In recent years, with the increasing output of residual sludge from brewing, the stockpile volume has gradually increased, and the treatment of residual sludge from brewing has become urgent. Therefore, since the applicant established a research team with Wu Yuanhui and Luo Suxing as the main leaders in 2020, he has taken the treatment of residual sludge from brewing as the main research direction project. In the process of carrying out educational and teaching activities, he combined "production-university-research" to carry out post-treatment research on residual sludge from brewing, in order to reduce the stockpile volume of residual sludge from brewing and reduce the cost of treating residual sludge from brewing, and formed a large number of research results, such as: Patent No. 2020106345491 A heteropolyacid-sludge-based adsorbent and its preparation method and application, sludge is used to prepare adsorbent products to improve adsorption performance; another example: Patent No. 2022106330974 A natural siderite-sludge-based composite material and its preparation method and application, using natural siderite and sludge to prepare composite materials, improving the performance of composite materials; another example: Patent No. 2022106330974 A natural siderite-sludge-based composite material and its preparation method and application, using natural siderite and sludge to prepare composite materials, improving the performance of composite materials; another example: Patent No. The patent application number is 2023108160243, a sludge-based biochar prepared from residual sludge from brewing, a method and an application thereof, the sludge is prepared into biochar and returned to the sludge to improve the sludge dewatering performance; another example: the patent application number is 2023108416211, a sludge-based biochar suspension for electrode modification, a preparation method and an application thereof, the sludge is prepared into a biochar suspension and used to improve the electrode sensitivity research; another example: the patent application number is 202410892193X, a biochar prepared from residual sludge from brewing, a method and an application thereof, the sludge is prepared into biochar and used as a raw material for soil conditioner preparation to reduce pesticide residues; a systematic study on the resource utilization of residual sludge from brewing has basically been formed, and it has also provided a rich practical and theoretical basis for the research team on the resource utilization of residual sludge from brewing. However, during the research process, the residual sludge from brewing needs to be dehydrated and dried so that the residual sludge from brewing can be further utilized and studied. Therefore, the dehydration and drying devices or equipment for residual sludge from brewing are taken as the research direction for further research.

[0003] Regarding the drying of brewing waste sludge, the efficiency of drying and carbonizing the waste sludge was considered. After thorough discussion and exploration by the research team, the research results of a continuous drying and carbonization device for brewing waste sludge were obtained, with patent number 202421570845X. However, before the waste sludge is sent to the drying station, it needs to be dehydrated. Otherwise, the drying energy consumption and cost will be high. Moreover, dehydration is also a conventional measure for brewing companies to detoxify and reduce the amount of waste sludge.

[0004] At present, there are many technologies for sludge dewatering research, but they all take into account that sludge contains not only free water but also bound water. Therefore, when dewatering sludge, it is necessary to consider the simultaneous removal of free water and bound water. Otherwise, it is still difficult to reduce the water content of sludge, resulting in high difficulty in sludge post-treatment. Therefore, pretreatment of sludge before dewatering has become a key step in sludge dewatering, and has been widely studied, forming a large number of pretreatment technologies, such as: exposing the intracellular water in the sludge so that it can be removed, reducing the water content of the sludge; for example: destroying the bond energy of bound water in the sludge, reducing the binding capacity of bound water, and improving the removal efficiency of bound water.

[0005] However, whether it is the treatment of intracellular water exposure or the treatment of bound water bond energy destruction, it can be achieved by adding chemical reagents or combining the addition of chemical reagents with physical treatment. How to add chemical reagents to the sludge for pretreatment of the sludge, and in what device to add them to reduce the amount of chemical reagents used and improve the sludge pretreatment efficiency have become the focus of research by those skilled in the art, and corresponding research literature has been formed. For example: Patent application No. 202410810626.2 discloses a sludge inlet device and a sludge dewatering system of a sludge dewatering equipment, including a vertical pump body and a reflux device, the vertical pump body is arranged at the top of the sludge tank, the feed end is connected to a liquid inlet pipe, and the discharge end is connected to a liquid outlet pipe: the reflux device includes a reflux pipe and a reflux valve, the first end of the reflux pipe is connected to the liquid outlet pipe, and the second end of the reflux pipe is connected to the sludge tank, etc., so as to achieve the purpose of improving work efficiency and reducing labor costs. Another example: Patent application number 202410387690.4 is a method and equipment for dewatering domestic sewage sludge, which includes a base, a sewage tank, a conveying unit, a concentration unit, a homogenizing unit, a first screw conveyor, a second screw conveyor, connecting pipes, multiple plate and frame filter presses, a filtrate collection tank, multiple filtrate collection pipes and a filtrate return pipe and other structural components. The residual reagents can be reused through reflux, thereby reducing the amount of reagents used and reducing costs.

[0006] However, the structure of the sludge dewatering pretreatment device in the existing technology is relatively complex and inconvenient to use, which makes it difficult to promote it in the industry. Moreover, since the residual sludge from brewing contains a high amount of organic matter, the viscosity of the residual sludge from brewing is relatively high, which makes it very easy to cause blockage of the sludge supply pipeline and the sludge slurry discharge pipeline when it is treated in the sludge dewatering pretreatment device, resulting in low efficiency of the residual sludge dewatering pretreatment of brewing.

[0007] Based on the above technical problems, the present invention provides a pretreatment device for dehydration of residual sludge from brewing wine. The device combines a cover body with a full-flow mixer so that the top of the full-flow mixer is closed, and the pressure effect is used to improve the discharge efficiency on the discharge pipe, thereby improving the pretreatment efficiency of dehydration of residual sludge from brewing wine.

[0008] The specific technical solutions are:

[0009] A pretreatment device for dehydrating residual sludge from brewing wine comprises: a full flow mixer and a cover body, wherein the cover body can cover the top of the full flow mixer, a discharge pipe is provided at the bottom of the full flow mixer, and a discharge valve is provided on the discharge pipe; the cover body is provided with a reagent input component, a stirring component, a feeding component and an observation hole; the reagent input component is used to input reagents into the full flow mixer, the stirring component is used to stir and mix the inside of the full flow mixer, and the feeding component is used to feed sludge slurry into the full flow mixer.

[0010] The reagent tube, stirring assembly and feeding assembly are integrated on the cover body, and the cover body is used to cover the full-flow mixer, so that the residual sludge from brewing wine passes through the feeding assembly and enters the full-flow mixer to add reagents for pretreatment. At the same time, it is stirred and mixed evenly, so that the gas generated by the pretreatment of the residual sludge from brewing wine continuously escapes to the top of the full-flow mixer, increasing the pressure in the full-flow mixer, so that the residual sludge from brewing wine can be discharged from the discharge pipe under the action of pressure when the pretreatment is completed and discharged from the discharge pipe, thereby avoiding clogging of the discharge pipe due to the discharge of the residual sludge from pretreatment, thereby improving the discharge efficiency.

[0011] In order to avoid opening the cover to add reagents and realize continuous replenishment of reagents in the pretreatment process of brewing residual sludge, preferably, the reagent input component includes a reagent tank and a reagent tube installed at the bottom end of the reagent tank, and the reagent tube passes through the cover and extends into the full flow mixer.

[0012] In order to control the amount of reagent added, preferably, a third flow valve is provided on the reagent tube.

[0013] In order to improve the covering strength between the cover and the full flow mixer, preferably, the cover and the full flow mixer are connected as a whole by a flange. In order to enhance the sealing performance, preferably, a sealing layer is provided between the connection between the cover and the full flow mixer.

[0014] In order to meet the requirements of reagent stirring and mixing in the pretreatment stage before dehydration of brewing waste sludge, so that the pretreatment of brewing waste sludge is in a relatively sealed full-flow mixer, and the subsequent discharge efficiency of the discharge pipe is improved, preferably, the stirring assembly includes a motor and a bearing installed on the cover body, a stirring shaft is provided in the bearing, and the top end of the stirring shaft is connected to the motor; the bottom end of the stirring shaft extends into the full-flow mixer, and a plurality of stirring blades are provided on the stirring shaft.

[0015] In order to reduce the difficulty of feeding the residual sludge from brewing, avoid the blockage of the feed pipe due to excessive viscosity, and improve the efficiency of feeding the residual sludge from brewing in the feed pipe, preferably, the feed assembly includes a feed pipe, a water pipe and a sludge pipe, one end of the feed pipe passes through the cover body and extends into the full-flow mixer, the other end of the feed pipe is provided with a sealing plug, and the sealing plug is provided with a first through hole and a second through hole; the water pipe is installed in the first through hole, the sludge pipe is installed in the second through hole, and the end of the water pipe located in the feed pipe is provided with a liquid outlet.

[0016] In order to be able to monitor the amount of residual brewing sludge added to the full-flow mixer and then accurately control the amount of reagent added, preferably, a second flow valve is provided on the feed pipe.

[0017] In order to prevent the residual sludge from brewing from entering the feed pipe and completely closing the feed pipe, making it difficult for water in the water adding pipe to penetrate into the residual sludge from brewing, it is preferred that the length of the water adding pipe extending into the feed pipe is greater than the length of the sludge pipe extending into the feed pipe, and a number of triangular cones are provided on the water adding pipe; the triangular cones are located between the left end of the sludge pipe and the left end of the water adding pipe.

[0018] In order to achieve water penetration when the triangular cone is grooved to reduce the viscosity of the residual sludge from brewing, it is preferred that the triangular cone is hollow inside and is connected to the inside of the water supply pipe; and a plurality of micropores are provided on the triangular cone.

[0019] In order to be able to draw a plurality of grooves on the residual brewing sludge in the feed pipe, it is preferred that the triangular cones are arranged in a staggered manner on the water adding pipe.

[0020] In order to more accurately determine the amount of residual sludge from brewing and configure the amount of reagent added, and at the same time meet the water replenishment demand during the stirring process of the residual sludge from brewing in the full flow mixer, preferably, a water supply pipe is provided on the side wall of the full flow mixer, a first flow valve is provided on the water supply pipe, and the water supply pipe is close to the top of the full flow mixer.

[0021] Compared with the prior art, the technical effects created by the present invention are embodied in:

[0022] The invention has a simple structure, is easy to operate, and is easy to promote and implement industrially. Moreover, the invention can fully utilize the gas generated by the pretreatment of the brewery surplus sludge before dehydration to increase the relatively sealed full flow mixer, so that when the brewery surplus sludge slurry is discharged from the discharge pipe after the pretreatment is completed, the discharge efficiency is improved and the blockage of the discharge pipe is avoided.

[0023] The present invention also improves the feed assembly integrated on the cover body, which is composed of a feed pipe, a sealing plug, a water adding pipe and a sludge pipe. When the residual sludge from brewing is added into the feed pipe, its viscosity in the feed pipe can be adjusted by adding water in time, thereby avoiding the residual sludge from brewing to block the feed pipe and improving the feeding efficiency.

[0024] In addition, the present invention also provides a water supply pipe on the full-flow mixer to avoid excessive addition of water into the feed component to dilute the brewing surplus sludge, which makes it difficult to control the feed amount of the brewing surplus sludge and causes the defect of accurate control of the reagent dosage. When water is added into the feed component, it can only prevent the brewing surplus sludge from clogging the feed pipe, and ensure that the amount of brewing surplus sludge entering the full-flow mixer is relatively accurately determined, and then ensure that the amount of reagent added is relatively accurately matched, thereby avoiding the defects of high cost caused by excessive reagent dosage and poor pretreatment effect of brewing surplus sludge caused by too little reagent dosage.
