Description

Technical Field

[0001] This utility model relates to the field of brewing equipment technology, specifically to a cellar maintenance device. Background Technology

[0002] In the brewing process of strong-aroma baijiu, when the mother vat in the fermentation pit is emptied and the pit is temporarily empty, a fall-prevention net is placed on the empty pit to prevent people from falling into the pit. At the same time, in order to prevent the pit mud from losing water and aging and to improve the quality of the pit mud, it is necessary to clean the empty pit and spray it with a maintenance solution to build and maintain a good microbial system for the pit mud, and maintain sufficient moisture, balanced nutrition, and a suitable pH environment. This series of measures is called pit maintenance.

[0003] Traditionally, cellars are maintained by workers periodically sprinkling a curing solution. However, because a fall-prevention net is placed above the cellar, direct contact of the curing solution with the net's ropes can accelerate its aging and failure. Therefore, the fall-prevention net must be removed each time the cellar is maintained, increasing labor intensity and increasing the risk of falls and other personal safety accidents. Furthermore, sprinkling the solution with a ladle during the maintenance process can easily damage the mud on the cellar walls and result in uneven application.

[0004] Based on production experience, the empty pit time is generally around 24 hours. Two pits are empty in each production cycle. According to the production process, the pits need to be maintained at least every 2 hours. A production team (three shifts) works 8 hours a day, so each shift needs to maintain the pits an average of about 8 times, approximately 2 times every 2 hours. In practice, workers have multiple tasks, making it difficult to consistently perform such frequent pit maintenance. Utility Model Content

[0005] To overcome the contradiction between the installation of anti-fall nets and the maintenance of the pit when the pit is empty, this utility model provides a pit maintenance device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: The cellar maintenance device includes a fall-prevention net, maintenance pipes, an external connection pipe, and a pump. The fall-prevention net is laid on top of the cellar. The maintenance pipe is fixedly installed on one side of the fall-prevention net and is connected to the external connection pipe. The pump is installed on the external connection pipe and is used to pump maintenance liquid from the outside into the external connection pipe. The maintenance pipe is connected to a nozzle for spraying maintenance liquid into the cellar.

[0007] This application integrates a maintenance pipe beneath the fall-prevention net and connects it to an external pipe, allowing the maintenance fluid to be obtained within the pipe. Simultaneously, nozzles are installed on the maintenance pipe to spray the maintenance fluid into the pit. This design enables pit maintenance work to be completed without removing the fall-prevention net, reducing labor intensity and improving production safety.

[0008] In some embodiments, the pump is connected to a timer switch to start and stop the pump according to a preset time, thereby achieving automated maintenance.

[0009] In some embodiments, multiple support pads are provided around the fall protection net so that the nozzle does not directly contact the ground when the fall protection net is laid flat.

[0010] In some embodiments, a cover is provided on the side of the fall protection net away from the nozzle to completely cover the fall protection net.

[0011] In some embodiments, the safety net is provided with multiple lifting rings for hoisting the safety net.

[0012] In some embodiments, a filter device is provided at the end of the outer pipe.

[0013] In some embodiments, the maintenance pipeline is provided with multiple nozzles, which are evenly distributed on the maintenance pipeline.

[0014] In some embodiments, the maintenance pipe is a rectangular pipe with multiple nozzles evenly distributed around its circumference.

[0015] In some embodiments, the nozzle is an atomizing nozzle, the rectangular pipe is configured such that each side is 50-70cm away from the inner wall of the adjacent pit, and the nozzle is configured to be inclined vertically downward toward the inner wall of the adjacent pit at a direction of 30°-60°.

[0016] In some embodiments, the fall arresting net includes two rectangular pipes, which are connected to an external pipe via a tee connector, and the two rectangular pipes are arranged side by side.

[0017] The beneficial effects of this utility model are: This application integrates a maintenance pipe beneath the fall-prevention net and connects it to an external pipe, allowing the maintenance fluid to be obtained within the pipe.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] The existing methods of using anti-fall nets and maintaining cellars have the following problems: (1) The existing anti-fall nets only serve a safety protection function and have a single function. (2) The maintenance frequency is high, the number of times the anti-fall nets are moved is relatively frequent, the labor intensity is high, and there is a safety risk of falling to the bottom of the cellar. (3) Since maintenance operations need to be completed twice every 2 hours on average, workers cannot maintain the cellars on time due to numerous work tasks. (4) Traditional cellar maintenance uses a ladle to splash the maintenance liquid, which has a large impact on the cellar wall, causing the cellar wall mud to fall off, and it cannot be guaranteed to be splashed evenly. (5) If the empty cellar is not properly maintained, the cellar mud will easily age, the quality of the base liquor will decline, the production process will be out of balance, and the production will be adversely affected. It is not conducive to protecting the activity of the cellar mud, the stability of the cellar, and the quality of the base liquor.

[0023] Meanwhile, the maintenance solution for the cellar needs to be artificially cultivated, which requires a complex process, a certain amount of time and cost. The existing method of maintaining the cellar by splashing the solution with a ladle results in most of the liquid settling at the bottom of the cellar, with relatively little maintenance solution on the cellar wall, poor uniformity, and failure to fully exert its effect.

[0024] To solve the aforementioned problems, such as Figure 1 As shown, this utility model provides a cellar maintenance device.

[0025] The cellar maintenance device includes a fall-prevention net 1, a maintenance pipe 2, an external connection pipe 5, and a pump 6. The fall-prevention net 1 is laid on top of the cellar. The maintenance pipe 2 is fixedly installed on one side of the fall-prevention net 1 and is connected to the external connection pipe 5. The pump 6 is installed on the external connection pipe 5 and is used to pump maintenance liquid from the outside into the external connection pipe 5. The maintenance pipe 2 is connected to a nozzle for spraying maintenance liquid into the cellar.

[0026] This application integrates a maintenance pipe 2 below the fall-prevention net 1 and connects it to an external pipe 5, allowing the maintenance fluid to be obtained within the maintenance pipe 2. Simultaneously, a nozzle is installed on the maintenance pipe 2 to spray the maintenance fluid into the pit. This design allows for pit maintenance work to be completed without removing the fall-prevention net 1, reducing labor intensity and improving production safety.

[0027] In practice, the fall protection net 1 completely covers the cellar. The maintenance pipe 2 can be made of food-grade PVC pipe or stainless steel pipe.

[0028] Given the high frequency of pit maintenance, to achieve timed maintenance and ensure more timely and accurate maintenance, pump 6 in this embodiment is connected to timer switch 7 to start and stop pump 6 according to preset times, thus achieving automated maintenance. The timer switch 7 can be implemented as a timer plug or a timer socket. Alternatively, a smart timer socket with a Bluetooth module can be selected, supporting remote adjustment of maintenance time and frequency by the system, adapting to unified management of multiple pits.

[0029] A control display panel can be installed on the timer socket to set the start interval and running time of pump 6, so as to realize the timed and quantitative spraying of maintenance liquid.

[0030] In this embodiment, multiple support pads 11 are arranged around the fall protection net 1 so that the nozzle does not directly contact the ground when the fall protection net 1 is laid flat.

[0031] Reference Figure 1 As shown, the support pads 11 are distributed at the four corners of the fall protection net 1 and in the middle of the long side.

[0032] In this embodiment, the support pad 11 is a block structure, which can be replaced by a ring-shaped rubber pad or other forms. It can also be sleeved on the outside of the nozzle to further improve safety.

[0033] In this embodiment, a cover 12 is provided on the side of the fall protection net 1 away from the nozzle to completely cover the fall protection net 1.

[0034] In practice, the fall protection net 1 is set above the pit. The side of the fall protection net 1 facing the pit is equipped with a curing pipe 2 and a nozzle, and the side away from the pit is equipped with a cover 12. The cover 12 completely covers the fall protection net 1 to prevent the curing liquid from evaporating and to maintain the temperature inside the pit.

[0035] Furthermore, the cover 12 can be configured as a transparent PVC cover or an insulating cotton cover. When configured as a transparent PVC cover, it is convenient to observe the curing condition. When configured as an insulating cotton cover, it can enhance the temperature maintenance effect of the pit. Both types of covers 12 can cover the anti-fall net 1, reducing the evaporation of the curing liquid.

[0036] In this embodiment, the fall protection net 1 is provided with multiple lifting rings 10 for lifting the fall protection net 1.

[0037] In this embodiment, the fall arrestor net 1 is equipped with lifting rings 10 for hoisting by a crane, facilitating production implementation. The position of the lifting rings 10 should be adjusted adaptively according to the actual structure of the product. For example, besides Figure 1 The form shown can also be implemented by setting one lifting ring 10 at the midpoint of the long side and the midpoint of the short side of the fall protection net 1, which can meet the needs of overhead crane lifting.

[0038] In this embodiment, a filter device 8 is provided at the end of the outer pipe 5.

[0039] Reference Figure 1 The outer connecting pipe 5 is inserted into the movable maintenance solution storage tank 9 to draw maintenance solution from the tank. A filter device 8 is provided at the end of the outer connecting pipe 5 to filter the maintenance solution. In this embodiment, the filter device 8 is a filter plug. In practice, it can also be replaced with a detachable filter connector with a filter screen, etc., for easy cleaning and replacement.

[0040] In practice, the portable curing solution storage tank 9 is equipped with a movable cover, which facilitates observation of the curing solution level and the addition of new curing solution. During shift handover, staff check whether the curing solution in the storage tank is sufficient and replenish it in a timely manner, and enter the new curing cellar time (once every 2 hours) and duration (30 seconds) on the control display panel.

[0041] To further ensure the uniformity of the curing solution spraying, this embodiment also optimizes the selection and placement of the curing pipe 2 and the nozzle.

[0042] Obviously, based on the function of spraying the curing liquid, the curing pipe 2 can be configured as one or more, and multiple pipes can be configured to be connected or independent, while one pipe can be configured as a closed loop or an open loop. The nozzle can be configured to be rotatable or fixed, and there are various options for selection. In this embodiment, the curing pipe 2 is configured as follows.

[0043] In this embodiment, the maintenance pipe 2 is equipped with multiple nozzles, which are evenly distributed on the maintenance pipe 2.

[0044] By configuring multiple nozzles, spraying efficiency and spray uniformity can be improved.

[0045] In this embodiment, the maintenance pipe 2 is a rectangular pipe with multiple nozzles evenly distributed around its circumference.

[0046] Based on the fact that the cellar is generally rectangular in shape in practice, it is preferable to set the maintenance pipe 2 as a rectangular pipe. With this implementation, and with the addition of multiple nozzles evenly distributed around the perimeter, the uniformity of spraying can be improved.

[0047] In this embodiment, the nozzle is an atomizing nozzle 3, the rectangular pipe is configured such that each side is 50-70cm away from the inner wall of the adjacent pit, and the nozzle is configured to be tilted vertically downwards towards the inner wall of the adjacent pit at a direction of 30°-60°.

[0048] The preferred nozzle configuration here is an atomizing nozzle 3, which is fixedly mounted on a rectangular pipe, and the tilt angle of the nozzle is limited to further improve the uniformity of spraying.

[0049] Reference Figure 1In this embodiment, the atomizing nozzles 3 are distributed on the rectangular pipe as follows: 3 are evenly distributed along the long side and 2 are evenly distributed along the short side, and they are vertically downward and inclined at 45° towards the inner wall of the pit.

[0050] In this embodiment, the fall protection net 1 includes two rectangular pipes, which are connected to the external pipe 5 through a tee connector 4, and the two rectangular pipes are arranged side by side.

[0051] This cellar maintenance device can be used for two adjacent cellars or a large, long cellar. When applied to a large cellar, it may also include a sill, dividing the large cellar into two smaller cellars.

[0052] This configuration increases the adaptability of the device, allowing two adjacent spraying areas to share the pump 6, external pipe 5, and timer switch 7, thus optimizing the structure and facilitating implementation.

[0053] The cellar maintenance device provided by this utility model can enrich the functions of the anti-fall net 1, realize the automation of cellar maintenance, reduce manual workload, and avoid the waste of maintenance solution and possible safety accidents during manual cellar maintenance. It can maintain the cellar at regular intervals and in quantitative amounts, which is conducive to maintaining the activity of the cellar mud, providing a suitable environment for microorganisms in the cellar mud (such as caproic acid bacteria, methanogens, etc.), maintaining the temperature, humidity and pH of the cellar, maintaining the stability of the cellar environment, ensuring the normal fermentation and improving the quality of the wine, while reducing the waste of maintenance solution caused by uneven application and gravity settling.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
