Technical Field

[0001] The invention relates to the technical field of bottled water filling, and more specifically, to a filling and disinfecting method for a clean water barrel. Background Art

[0002] As people's requirements for drinking water quality increase, water treatment technology continues to develop. There are various ways to produce bottled water on the market. Many small bottled water plants use manual operations to rinse and disinfect the inside of the clean water barrels, or use machines for disinfection. In the multi-station machine disinfection process, the clean water barrels are easily contaminated during the station switching process. At the same time, during the use of the filling water machine, it is easily affected by the environment and manual operations, resulting in water source pollution;

[0003] In view of the problem that the water source in the above-mentioned water purification barrel is easily contaminated, a filling and disinfection method for a water purification barrel is proposed to achieve all-round disinfection of the inner wall of the water purification barrel without dead angles, improve filling efficiency and accuracy, and ensure the water safety of users. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a filling and disinfecting method for a water purification barrel to solve the problems existing in the above-mentioned background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A filling and disinfection method for a water purification barrel, comprising:

[0006] Step A: Install the clean water barrel: insert the clean water barrel upside down at 45 degrees into the rotating filling head of the filling machine. The rotating filling head recognizes the mouth of the clean water barrel and locks the mouth of the clean water barrel.

[0007] Step B, disinfecting and sterilizing the inner cavity of the clean water bucket: the rotary filling head rotates, driving the clean water bucket to rotate, so that the barrel mouth of the clean water bucket is vertically downward along the gravity direction, and the rotary filling head sprays disinfectant acid into the inner cavity of the clean water bucket to complete the disinfection and sterilization of the inner cavity of the clean water bucket;

[0008] Step C, cleaning and filtering the inner cavity of the clean water bucket: the rotating filling head sprays clean cooling water into the inner cavity of the clean water bucket, thereby bringing out the disinfecting acid in the inner cavity of the clean water bucket and flowing into the rotating filling head from the inner cavity of the clean water bucket;

[0009] Step D, rotating the water purification barrel: rotating the filling head to drive the water purification barrel to rotate, so that the barrel mouth of the water purification barrel faces upward along the direction of gravity;

[0010] Step E: Filling the water tank with purified water: Rotate the filling head to pour purified water into the inner cavity of the water tank to complete the process of filling purified water;

[0011] Step F: Disassembly and separation of the clean water barrel: When a certain mass of pure water is filled into the clean water barrel, the mouth of the clean water barrel is separated from the rotating filling head due to the increase of its own gravity, thereby completing the disassembly and separation of the clean water barrel and the rotating filling head.

[0012] Optionally, the disinfecting acid solution in step C comprises the following components: 0.1-0.5 wt % peracetic acid, 1-3 wt % food-grade citric acid, and the balance is deionized water.

[0013] Optionally, the rotating filling head in step E fills the inner cavity of the clean water bucket with pure water in three stages:

[0014] Stage 1: Fill to 30% of the total capacity at a flow rate of 500-800 mL / min;

[0015] Stage 2: Fill to 80% of the total capacity at a flow rate of 300-500 mL / min;

[0016] Stage 3: Fill to rated capacity at a flow rate of 100-200 mL / min.

[0017] Optionally, step A also includes: measuring the size of the mouth of the clean water bucket to obtain the rated capacity of the clean water bucket.

[0018] Optionally, the step F also includes: after the clean water bucket is disassembled and separated from the rotary filling head, the rotary filling head performs secondary ultraviolet disinfection on the bucket mouth, and the irradiation intensity is ≥8000μW / cm 2 , irradiation time 10-15 seconds.

[0019] Optionally, the rotary filling head is driven by a servo motor with a speed control accuracy of ±1rpm and is equipped with a torque overload protection device.

[0020] Optionally, the rotary filling head in step E is provided with a quantitative filling module; the quantitative filling module adopts a mass flow meter for measurement with an accuracy of ±0.1% and is equipped with an automatic deviation correction device.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. The rotating filling head is combined with a nozzle that can spray medicine and clean water at different times. The disinfectant acid can be effectively sprayed onto the inner wall of the clean water bucket, which can achieve an effective bacteria killing effect. At the same time, the residual disinfectant acid can be washed out of the clean water bucket by spraying clean water, thereby achieving the disinfection and filling of the clean water bucket.

[0023] 2. The innovative three-stage flow rate control filling increases the filling efficiency, avoids the overflow or spillage of the pure water bucket, and improves the filling accuracy of the clean water bucket.

[0024] 3. A new method for fully automatic disinfection, cleaning and filling of clean water buckets. Especially in extremely limited places, the up and down rotation method is adopted to achieve fully automatic disinfection, cleaning and filling on the spot. Since the bucket does not move left or right during the whole process, fully automatic disinfection, cleaning and filling are achieved in a very small space. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] The present invention provides a filling and disinfecting method for a water purification bucket, such as Figure 1 As shown, including:

[0032] Step A: Install the clean water barrel: insert the clean water barrel upside down at 45 degrees into the rotating filling head of the filling machine. The rotating filling head recognizes the mouth of the clean water barrel and locks the mouth of the clean water barrel.

[0033] Step B, disinfecting and sterilizing the inner cavity of the clean water bucket: the rotary filling head rotates, driving the clean water bucket to rotate, so that the barrel mouth of the clean water bucket is vertically downward along the gravity direction, and the rotary filling head sprays disinfectant acid into the inner cavity of the clean water bucket to complete the disinfection and sterilization of the inner cavity of the clean water bucket;

[0034] Step C, cleaning and filtering the inner cavity of the clean water bucket: the rotating filling head sprays clean cooling water into the inner cavity of the clean water bucket, thereby bringing out the disinfecting acid in the inner cavity of the clean water bucket and flowing into the rotating filling head from the inner cavity of the clean water bucket;

[0035] Step D, rotating the water purification barrel: rotating the filling head to drive the water purification barrel to rotate, so that the barrel mouth of the water purification barrel faces upward along the direction of gravity;

[0036] Step E: Filling the water tank with purified water: Rotate the filling head to pour purified water into the inner cavity of the water tank to complete the process of filling purified water;

[0037] Step F: Disassembly and separation of the clean water barrel: When a certain mass of pure water is filled into the clean water barrel, the mouth of the clean water barrel is separated from the rotating filling head due to the increase of its own gravity, thereby completing the disassembly and separation of the clean water barrel and the rotating filling head.

[0038] In this embodiment, a three-claw chuck is used as the structure for clamping the mouth of the clean water bucket in the rotating filling head. The elastic clamping force of the three-claw chuck is greater than the gravity of the empty bucket. The mouth of the empty bucket will not separate from the chuck at any position during the up and down rotation process, and the empty bucket will be suspended at the chuck position.

[0039] In other embodiments, the residual water flows from the inner cavity of the clean water barrel into the rotary filling head, and is drained back to the medicine tank for repeated use, thereby saving costs and improving disinfection efficiency.

[0040] In other embodiments, during the filling process, the gravity in the barrel is increased, and the barreled water filled with purified water naturally drops down, detaches from the filling chuck, and falls onto the barrel receiving platform for the user to take away, thereby further increasing the adaptability to different scenarios.

[0041] Furthermore, the disinfecting acid solution in step C comprises the following components: 0.1-0.5wt% peracetic acid, 1-3wt% food-grade citric acid, and the balance is deionized water.

[0042] Furthermore, the rotary filling head in step E fills the inner cavity of the clean water bucket with pure water in three stages:

[0043] Stage 1: Fill to 30% of the total capacity at a flow rate of 500-800 mL / min;

[0044] Stage 2: Fill to 80% of the total capacity at a flow rate of 300-500 mL / min;

[0045] Stage 3: Fill to rated capacity at a flow rate of 100-200 mL / min.

[0046] In a specific embodiment, the filling states of the rotating filling head into the inner cavity of the clean water bucket are respectively an initial turbulent state to quickly fill the main volume, a mid-term transition flow to stabilize the flow rate, and a final laminar flow to ensure accurate metering.

[0047] Furthermore, the step A also includes: measuring the size of the mouth of the clean water bucket, and then obtaining the rated capacity of the clean water bucket.

[0048] Furthermore, the step F also includes: after the clean water bucket and the rotary filling head are disassembled and separated, the rotary filling head performs secondary ultraviolet disinfection on the bucket mouth, the irradiation intensity is ≥8000μW / cm2, and the irradiation time is 10-15 seconds.

[0049] Furthermore, the rotary filling head is driven by a servo motor with a speed control accuracy of ±1rpm and is equipped with a torque overload protection device.

[0050] Furthermore, the rotary filling head in step E is provided with a quantitative filling module; the quantitative filling module adopts a mass flow meter for measurement with an accuracy of ±0.1% and is equipped with an automatic deviation correction device.

[0051] The present invention provides a filling and disinfection method for a clean water bucket. A rotary filling head is combined with a rotary spraying technology, so that the disinfecting acid can be effectively sprayed to cover the inner wall of the clean water bucket, thereby achieving an effective bacteria killing effect. At the same time, by spraying clean water, the residual disinfecting acid can be washed out of the clean water bucket, thereby achieving the post-disinfection filling of the clean water bucket; the innovative three-stage flow rate controlled filling increases the filling efficiency, avoids the overflow or spillage of pure water out of the clean water bucket, and improves the filling accuracy of the clean water bucket; the significant improvement in the degree of automation does not require multiple workstations as in the traditional filling process. The design of the rotary filling head only requires a single workstation to meet the production requirements, further saving work space.

[0052] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
