Description

Technical Field

[0001] This application relates to the field of mechanical technology for cleaning, bleaching, and drying vegetables and fruits, specifically to a two-way water spray pipe assembly and a ginger washing machine. Background Technology

[0002] In the industrial processing of fruits and vegetables, spray washing machines are a common type of cleaning equipment. They use high-pressure water jets to spray and rinse the surface of fruits and vegetables, effectively removing dirt, pesticide residues, and microorganisms. Spray washing machines typically consist of a water pump, water delivery pipes, a two-way water flow spray pipe assembly, and nozzles. The two-way water flow spray pipe assembly often uses rigid pipes (such as stainless steel or PVC pipes) connected end-to-end with bends to form a serpentine arrangement, ensuring that the spray water can evenly cover the surface of the fruits and vegetables to be cleaned.

[0003] In actual operation, the mechanical vibrations generated by the water pump are transmitted to the bidirectional water flow spray pipe assembly through the water delivery pipe. Since the bidirectional water flow spray pipe assembly is typically composed of straight pipe sections and curved pipe sections connected by welding or threading, and the curved sections are often manufactured using bending processes, their mechanical strength is relatively low. Especially at the connection between the curved and straight pipes, stress concentration can easily occur, making it a structural weak point. After prolonged exposure to vibration, cracks or breaks can easily appear at the connection, leading to water leakage. This not only reduces cleaning efficiency but may also affect the cleaning effect due to a drop in water pressure. Furthermore, damage to the bidirectional water flow spray pipe assembly requires shutdown for repair, increasing equipment maintenance costs and affecting production continuity.

[0004] When cleaning ginger mechanically, the ginger has an irregular shape, an uneven surface, and many crevices, which can easily trap dirt, impurities, and microorganisms. If the cleaning is not thorough, it can easily leave mud and sand on the surface. However, the ginger skin is very thin, and excessive scrubbing can easily damage it, causing juice loss, which affects the taste of the ginger and its subsequent preservation. Summary of the Invention

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a bidirectional water flow spray pipe assembly and a ginger washing machine, the technical solution of which includes:

[0006] A bidirectional water flow spray pipe assembly includes an inlet pipe, an outlet pipe, two longitudinal pipes, and multiple horizontal pipes. The two longitudinal pipes are arranged horizontally side by side and spaced apart. The inlet pipe is located at one end of the two longitudinal pipes and is connected and communicates with the two longitudinal pipes. The outlet pipe is located at the other end of the two longitudinal pipes and is connected and communicates with the two longitudinal pipes. Multiple first openings are provided on the side of the two longitudinal pipes that are close to each other, and the first openings on the two longitudinal pipes correspond one-to-one. Multiple horizontal pipes are arranged horizontally between the two longitudinal pipes. The two ends of each horizontal pipe are inserted into the first openings on the two longitudinal pipes and are welded and communicate with the two horizontal pipes. Multiple nozzles are installed on the horizontal pipes, the inlet pipe, and the outlet pipe.

[0007] In a preferred embodiment of this application, the inlet pipe and outlet pipe are provided with a second opening that matches the longitudinal pipe, and the longitudinal pipe is inserted into the second opening and welded and connected to the inlet pipe and outlet pipe.

[0008] In a preferred embodiment of this application, one end of the water outlet pipe and the water inlet pipe are connected to a longitudinal pipe through a bend, the other end of the water outlet pipe is the water outlet, and the other end of the water inlet pipe is the water inlet.

[0009] In a preferred embodiment of this application, the nozzles on two adjacent horizontal pipes are staggered.

[0010] In a preferred embodiment of this application, each of the spray heads includes a nozzle and a duckbill spray head. One end of the duckbill spray head is connected to the horizontal pipe, and the width of the duckbill spray head gradually increases from one end to the other. The nozzle communicates with the interior of the horizontal pipe and extends into the narrower end of the duckbill spray head.

[0011] Based on the aforementioned bidirectional water flow spray pipe assembly, this application also proposes a ginger washing machine, comprising a soaking pool and a sprayer arranged sequentially. The soaking pool is equipped with an aeration pipe. The sprayer includes a frame, a conveyor belt mounted on the frame, and two of the aforementioned bidirectional water flow spray pipe assemblies respectively mounted above and below the conveyor belt. The conveyor belt is used to receive ginger passing through the soaking pool and transport the received ginger to the space between the two bidirectional water flow spray pipe assemblies for spraying and cleaning. The frame is provided with a water collection tank below the bidirectional water flow spray pipe assemblies, and a filter screen is installed at the upper end of the water collection tank.

[0012] In a preferred embodiment of this application, the filter screen is detachably installed at the upper end of the water collection tank.

[0013] The beneficial effects of this utility model are:

[0014] In this application, after opening the longitudinal pipe, the horizontal pipe is inserted into the opening and welded to the longitudinal pipe by welding, avoiding the use of a bend. When the water pump delivers spray water to the bidirectional water flow spray pipe group, even if the vibration generated by the water pump is transmitted to the horizontal and longitudinal pipes, the horizontal and longitudinal pipes are connected by welding, resulting in higher mechanical strength. The connection between the horizontal and longitudinal pipes will not break due to vibration.

[0015] Furthermore, in this application, water can enter from both ends of each horizontal pipe equipped with a nozzle, achieving bidirectional water intake in the horizontal pipe. The spray water entering from the water inlet pipe can flow into the horizontal pipe in both directions. After the spray water flows into the bidirectional water flow spray pipe assembly, it is more evenly dispersed, ensuring that all nozzles can spray spray water more evenly.

[0016] During the initial cleaning, the mud and sand attached to the surface of the ginger are removed. After the initial cleaning is completed, the ginger is conveyed to the conveyor belt. The conveyor belt transports the received ginger to the area between two bidirectional water flow spray pipe groups for spray cleaning. The two bidirectional water flow spray pipe groups simultaneously rinse the ginger from above and below, thoroughly cleaning the lower surface of the ginger and any stubborn stains and attachments remaining on the lower surface, ensuring the cleaning effect of the ginger and avoiding over-scrubbing of the ginger and causing damage to the ginger surface.

[0024] Reference Figure 1 This application proposes an embodiment of a bidirectional water flow spray pipe assembly, which includes an inlet pipe 231, an outlet pipe 232, two longitudinal pipes 233, and multiple horizontal pipes 234. The two longitudinal pipes 233 are arranged horizontally side by side and spaced apart. The inlet pipe 231 is located at one end of the two longitudinal pipes 233 and is connected and communicates with the two longitudinal pipes 233. The outlet pipe 232 is located at the other end of the two longitudinal pipes 233 and is connected and communicates with the two longitudinal pipes 233. Multiple first openings are provided on the side of the two longitudinal pipes 233 that are close to each other, and the first openings on the two longitudinal pipes 233 correspond one to one. Multiple horizontal pipes 234 are arranged horizontally between the two longitudinal pipes 233. The two ends of each horizontal pipe 234 are inserted into the first openings on the two longitudinal pipes 233 and are welded and communicated with the two horizontal pipes 234. Multiple nozzles 235 are installed on one side of each horizontal pipe 234.

[0025] In this application, after opening the longitudinal pipe 233, the horizontal pipe 234 is inserted into the opening and welded to the longitudinal pipe 233 by welding, avoiding the use of bends. When the water pump delivers spray water to the bidirectional water flow spray pipe group, even if the vibration generated by the water pump is transmitted to the horizontal pipe 234 and the longitudinal pipe 233, the horizontal pipe 234 and the longitudinal pipe 233 are connected by welding, resulting in higher mechanical strength. The connection between the horizontal pipe 234 and the longitudinal pipe 233 will not break due to vibration.

[0026] Furthermore, in this application, water can enter from both ends of each horizontal pipe 234 equipped with a spray head, realizing bidirectional water intake of the horizontal pipe 234. The spray water entering from the water inlet pipe 231 can flow into the horizontal pipe 234 in both directions. After the spray water flows into the bidirectional water flow spray pipe group, it is more evenly dispersed, ensuring that the spray water from all the spray heads can be more even.

[0027] Specifically, the inlet pipe 231 and the outlet pipe 232 are provided with a second opening that matches the longitudinal pipe 233. The longitudinal pipe 233 is inserted into the second opening and welded and connected to the inlet pipe 231 and the outlet pipe 232 to ensure that the connection between the longitudinal pipe and the inlet pipe and the outlet pipe is fixed.

[0028] In this embodiment, one end of the water outlet pipe 232 and the water inlet pipe 231 are connected to a longitudinal pipe 233 through a bend pipe 236, the other end of the water outlet pipe 232 is the water outlet, and the other end of the water inlet pipe 231 is the water inlet.

[0029] Preferably, the nozzles 235 on two adjacent spray pipes 232 are staggered to spray and rinse different parts of the ginger, ensuring the cleaning effect.

[0030] Preferably, each of the nozzles 235 includes a nozzle 2351 and a duckbill spray head 2352. One end of the duckbill spray head 2352 is connected to the horizontal tube 234, and the width of the duckbill spray head 2352 gradually increases from one end to the other. The nozzle 2351 communicates with the interior of the horizontal tube 234 and extends into the narrower end of the duckbill spray head 2352.

[0031] Spray water flows from one end of the duckbill spray head 2352 into the other end. The flat head is formed by flattening the pipe, which causes the width of the duckbill spray head 2352 to gradually increase from one end to the other, so that the spray coverage area gradually increases. This ensures that the water volume sprayed from the spray head 235 is uniform in the middle and on both sides, avoiding uneven water flow distribution due to higher water pressure in the middle and lower water pressure on both sides, which would affect the spraying effect on the ginger.

[0032] Based on the above, this application also proposes a ginger washing machine, including a soaking pool 10 and a sprayer 20 arranged in sequence. The soaking pool 10 is provided with an aeration pipe 11. The sprayer 20 includes a frame 21, a conveyor belt 22 installed on the frame 21, and two bidirectional water flow spray pipe groups 23 as described above, respectively installed above and below the conveyor belt 22. The conveyor belt 22 is used to receive ginger passing through the soaking pool 10 and transport the received ginger to the two bidirectional water flow spray pipe groups 23 for spraying and cleaning. The frame 21 is provided with a water collection tank 24 below the bidirectional water flow spray pipe groups 23, and a filter screen 25 is installed on the upper end of the water collection tank 24.

[0033] Specifically, the soaking pool 10 is equipped with an aeration pipe 11, and a primary cleaning and conveying platform is installed inside the soaking pool 10. After the ginger is sent into the soaking pool 10, the aeration pipe 11 works to perform primary cleaning on the ginger, removing the mud and sand attached to the surface of the ginger. After the cleaning is completed, the primary cleaning and conveying platform conveys the ginger after primary cleaning to the conveyor belt 22.

[0034] Baking soda can also be added to the soaking pool 10, and the ginger can be soaked in the soaking pool 10 for a period of time to remove pesticide residues on the surface of the ginger.

[0035] After the initial cleaning is completed, the ginger is conveyed to the conveyor belt 22. The conveyor belt 22 conveys the received ginger to the area between two bidirectional water flow spray pipe groups 23 for spray cleaning. The two bidirectional water flow spray pipe groups 23 simultaneously rinse the ginger from above and below, thoroughly cleaning the lower surface of the ginger and any stubborn stains and attachments remaining on the lower surface, ensuring the cleaning effect of the ginger and avoiding over-scrubbing of the ginger and causing damage to the ginger surface.

[0036] Preferably, the filter screen 25 is detachably installed on the upper part of the water collection tank 24, so that the filter screen 25 can be removed and cleaned by the staff, avoiding the accumulation of residue on the filter screen 25. A baffle is provided on the upper periphery of the water collection tank 24, and the filter screen 25 is detachably installed on the upper part of the water collection tank 24 by preventing it from being blocked.

[0037] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
