Detailed Implementation

[0015] Example

[0016] See appendix Figure 1 Appendix Figure 2 Appendix Figure 3The present invention relates to a filtration device for liquid in a bottle washing machine, comprising a vertical backwash filter 1 and a backwash pump assembly. The liquid inlet pipe 113 of the vertical backwash filter connects to two hard particulate interceptors 201, which are vertically arranged in parallel. Each hard particulate interceptor is equipped with a liquid inlet valve 402 and a liquid outlet valve 403. Each hard particulate interceptor includes a stainless steel outer tank 204 and a stainless steel inner tank 205, with a liquid inlet 202 located at the top of the outer tank. The upper part of its side wall is provided with a liquid discharge port 203. The upper part of the stainless steel inner cylinder is provided with a rectifier zone, the middle part with an interception zone, and the lower part with a settling zone. An annular baffle 211 is provided between the interception zone and the settling zone. The bottom of the stainless steel inner cylinder is provided with a drain hole 209. The interception zone is provided with multiple interception holes 206. The vertical backwash filter includes a pressure tank 101, a cylindrical filter screen 106, a backwashing assembly, and a drive mechanism. The drive mechanism is installed on the top of the pressure tank, and a cleaning liquid output device is installed on the upper part of the pressure tank. Lan 103, the cylindrical filter screen is installed in the middle of the pressure tank, and the liquid input pipe is installed at the bottom of the pressure tank; the backwash assembly includes a vertical long shaft 102, a sewage collection pipe assembly 110, and a backwash water distribution pipe 109; the head of the vertical long shaft is connected to the drive mechanism, a high-pressure water chamber is provided at the upper part of the vertical long shaft, a sewage collection channel is provided at the lower part of the vertical long shaft, the inlet end of the high-pressure water chamber is connected to the high-pressure water outlet end of the backwash pump assembly, and the outlet end of the high-pressure water chamber is connected to the... The backwash water distribution pipe is connected; multiple sewage collection pipe assemblies are installed at the lower part of the vertical long shaft, and the cavity of the sewage collection pipe assembly is connected to the sewage collection cavity; the sewage collection pipe assembly is located inside the cylindrical filter screen, the backwash water distribution pipe is located outside the cylindrical filter screen, and multiple backwash nozzles 116 are provided on the backwash water distribution pipe; a sewage discharge pipe assembly is provided at the bottom of the pressure tank, and the sewage collection cavity is connected to the sewage discharge pipe assembly; a water cooling mechanism is provided at the upper end of the vertical long shaft.

[0017] See appendix Figure 1In this embodiment, the vertical backwash filter and backwash pump assembly are existing technologies and will not be described in detail. The liquid inlet pipe 113 of the vertical backwash filter is connected to two rigid particulate interceptors 201. The two rigid particulate interceptors are set vertically in parallel. Each rigid particulate interceptor is equipped with a liquid inlet valve 402 and a liquid outlet valve 403. Considering that the liquid from the bottle washing machine carries many glass fragments and gravel, the rigid particulate interceptors are set vertically, which allows glass fragments, gravel, and other debris entering the rigid particulate interceptors to quickly sink to the bottom, effectively preventing glass fragments and other debris from entering the vertical backwash filter. The liquid injection valve 402 of the hard particulate interceptor 201 and the liquid injection valve 302 of the hard particulate interceptor 301 are connected in parallel (connected) through a pipe 401, which is connected to the liquid discharge pipe A of the bottle washing machine. The liquid discharge valve 403 and the liquid discharge valve 405 of the hard particulate interceptor 201 and the hard particulate interceptor 301 are connected in parallel through a conveying pipe 404, which is connected to the liquid input pipe 113 of the vertical backwash filter.

[0018] See appendix Figure 2 Appendix Figure 3 (Appendix) Figure 3 It is attached Figure 2 (Enlarged view of section B) In this embodiment, the hard particulate matter interceptor includes a stainless steel outer barrel 204 and a stainless steel inner barrel 205. An inlet connection flange (liquid inlet) 202 is provided at the top of the stainless steel outer barrel, and a buffer water chamber is provided at the top. A stainless steel inner barrel mounting flange is provided at the bottom of the buffer water chamber. An outlet flange (liquid outlet) 203 is provided on the upper part (side wall) of the stainless steel outer barrel. A support base 210 is provided at the bottom of the stainless steel outer barrel to improve the stability of the stainless steel inner barrel. A rectifier zone is provided at the upper part of the stainless steel inner barrel, an interception zone is provided in the middle, and a settling zone is provided at the lower part. An annular baffle 211 is provided between the interception zone and the settling zone. The interception zone is provided with multiple interception holes 206 to prevent larger glass fragments and gravel from passing through the stainless steel inner barrel and entering the stainless steel outer barrel. The lower part of the settling zone is a collection hopper 207 to collect larger glass fragments and gravel. A drain hole 209 is provided at the bottom of the settling zone. No water passage holes are provided in the rectifier zone and the settling zone. The rectifier zone is positioned corresponding to the outlet flange. The annular baffle is a perforated plate. The purpose of setting the annular baffle is to prevent hard particles entering the collection hopper from flowing back into the interception zone with the liquid.

[0019] See appendix Figure 3 To prevent flexible fibers carried in the bottle washing machine liquid from entering the vertical backwash filter, flexible fiber capturing ratchet 208 is provided on the inner edge of the interception hole. In this embodiment, multiple flexible fiber capturing ratchet is provided on the inner edge of the interception hole. The capturing ratchet can lock the flexible fibers floating in the liquid, such as plastic fiber packaging bag fragments or strips.

[0020] In existing technology, the discharge liquid from bottle washing machines carries solid particles (such as glass shards and large-volume gravel) and long fibers (such as fragments of plastic fiber packaging bags). The discharge liquid from the bottle washing machine is injected into the rectifying zone from the top of the hard particle interceptor. The flow velocity of the liquid is different from the movement velocity of the hard particles. When the hard particles pass through the buffer water chamber and the rectifying section, they form an inertia that causes them to settle rapidly downwards along the stainless steel inner cylinder wall. When passing through the interception section, larger particles continue to settle downwards along the wall until they reach the bottom. The fibers floating in the liquid are captured by the capture ratchet when they pass through the interception hole. The liquid without solid particles passes through the interception hole into the cavity between the stainless steel inner cylinder and the stainless steel outer cylinder, and then rises to the outlet flange for discharge.

[0021] In this embodiment, when cleaning the hard particulate matter interceptor, two hard particulate matter interceptors can be used alternately to achieve online cleaning without stopping the machine. For example, the liquid injection valve 402 and the liquid discharge valve 403 are closed, the top end cap of the hard particulate matter interceptor 201 is opened, the stainless steel inner cylinder is removed, cleaned, and then installed into the stainless steel outer barrel. When the stainless steel inner cylinder is removed from the stainless steel outer barrel, all the bottle washing machine liquid remaining in the cylinder is discharged into the stainless steel outer barrel through the drain hole 209. Therefore, cleaning the stainless steel inner cylinder will not result in the loss of bottle washing machine liquid. In this embodiment, the liquid injection valve 402 and the liquid discharge valve 403, and the liquid injection valve 302 and the liquid discharge valve 405 can be either manual or electric valves. The opening method of the top end cap of the hard particulate matter interceptor and the method of removing the stainless steel inner cylinder are prior art and will not be described.

[0022] See appendix Figure 4In this embodiment, the vertical backwash filter includes a pressure tank 101, a cylindrical filter screen 106, a backwash assembly, and a drive mechanism. The drive mechanism includes a motor 2 and a reducer 3. A cleaning liquid output flange 103 is installed on the upper part of the pressure tank, the cylindrical filter screen is installed in the middle of the pressure tank, and the liquid input pipe is installed at the bottom of the pressure tank. The backwash assembly includes a vertical long shaft 102, a sewage collection pipe assembly 110, and a backwash water distribution pipe 109. The head (upper part) of the vertical long shaft is mechanically connected to the drive mechanism. A high-pressure water chamber 104 is provided on the upper part of the vertical long shaft, and a sewage collection channel 111 is provided on the lower part of the vertical long shaft. The inlet end 108 of the high-pressure water chamber is connected to the high-pressure water outlet end of the backwash pump assembly (the backwash pump assembly is prior art, see attached). (Not shown in the figure) The outlet end of the high-pressure water chamber is connected to the backwash water distribution pipe; multiple sewage collection pipe assemblies are installed at the lower part of the vertical long axis, and the cavity of the sewage collection pipe assembly is connected to the sewage collection channel; the sewage collection pipe assembly is located inside the cylindrical filter screen, and the backwash water distribution pipe is located outside the cylindrical filter screen; the backwash water distribution pipe is two L-shaped pipe fittings installed symmetrically on an axis, including a horizontal pipe section 114 and a vertical pipe section 115; multiple backwash nozzles 116 are provided on the vertical pipe section 115; a sewage discharge pipe assembly is provided at the bottom of the pressure tank, and the sewage collection channel is connected to the sewage discharge pipe assembly. The sewage discharge pipe assembly includes a horizontally arranged sewage discharge pipe 107, a solenoid valve installed in the sewage discharge pipe, and a backwash water discharge valve seat 112. The vertical backwash filter is prior art and will not be described in detail.

[0023] See appendix Figure 5 In this embodiment, to prevent the flexible fibers entering the vertical backwash filter from becoming entangled in the backwash water inlet pipe assembly or the cylindrical filter screen, multiple scissor blades 105 are installed in the middle of the vertical long axis, and these scissor blades are disposed between the backwash water inlet pipe assemblies. In actual use, unintercepted packaging bag fragments entering the vertical backwash filter often become entangled in the backwash water inlet pipe assembly or the cylindrical filter screen, affecting filtration efficiency. The scissor blades can break up the flexible fibers and then send them into the wastewater collection chamber.

[0024] In this embodiment, to prevent dirt buildup at the bottom of the vertical backwash filter, multiple stainless steel agitator wires 118 are installed at the bottom of the backwash water distribution pipe. The base of the stainless steel agitator wire (where it is installed in the backwash water distribution pipe) is designed as a spiral spring structure, and the head is a needle-shaped structure. In the prior art, small particles in the bottle washing machine's liquid will settle at the bottom of the vertical backwash filter. If not cleaned in time, this will form scale, reducing filtration efficiency. The stainless steel agitator wires reciprocate with the backwash water distribution pipe, agitating the small particles and discharging them from the vertical backwash filter with the bottle washing machine's liquid. Alternatively, a cleaning nozzle 117 is installed at the bottom of the backwash water distribution pipe. The high-pressure water jet from the cleaning nozzle can also agitate the small particles and discharge them from the vertical backwash filter with the bottle washing machine's liquid.

[0025] See appendix Figure 6 (Appendix) Figure 6 It is attached Figure 4 (Partial enlarged view of section C). In this embodiment, the temperature of the washing liquid inside the pressure tank is 90°C. The drive mechanism installed on the top of the pressure tank includes a motor 2, a reducer 3, a vertical long shaft housing 4, and the head (upper part) of the vertical long shaft 102 is installed together with the reducer. Under normal operating conditions, the washing liquid continuously heats the vertical long shaft. To avoid the high temperature affecting the mechanical performance of the sealing mechanism installed on the vertical long shaft, a water cooling mechanism is installed at the upper end of the vertical long shaft to reduce the temperature of the sealing mechanism and ensure the normal operation of the vertical backwash filter. In this embodiment, the water cooling mechanism consists of a cooling water inlet 6, an inlet channel 9, a seal 8, an outlet channel 7, and a cooling water outlet 5. The seal has an annular water channel.
