Description

Technical Field

[0001] This utility model relates to the field of biomass fertilizer preparation technology, and in particular to a bacterial liquid spraying device. Background Technology

[0002] The raw materials for preparing biomass fertilizer are mainly organic materials such as vegetable straw, which are placed in a fermentation tank, and then additives such as bacterial solution are added. After fermentation, a fertilizer that can be used directly is formed. The injection of bacterial solution is a crucial step in the preparation of biomass fertilizer, and it is usually added to the fermentation tank by spraying. For example, Chinese Patent 202221667893.1 discloses a bacterial solution spraying device for biomass fertilizer preparation. A flexible hose is connected to one side of the fixed shell, and a set of spray pipes is provided on the other side of the fixed shell. Adjacent spray pipes are connected to each other, and a nozzle is connected to the bottom of the spray pipes to spray the bacterial solution.

[0003] For the aforementioned existing technologies, microbial hyphae, spores, or undissolved culture medium components (such as sugars and peptones) in the bacterial solution may form particulate matter, and the bacterial solution residue may form hard lumps after drying, which may adhere to the inner wall of the tube or nozzle, easily causing nozzle blockage. This requires periodic shutdowns to clean the nozzles or replace parts, necessitating frequent manual maintenance and affecting production efficiency. Utility Model Content

[0004] In view of this, it is necessary to provide a bacterial liquid spraying device to solve the technical problem in the prior art where bacterial liquid particles and hard lumps formed after drying adhere to the inner wall of the pipe or nozzle, easily causing nozzle blockage.

[0005] To achieve the above-mentioned technical objectives, the present invention provides a bacterial liquid spraying device, comprising:

[0006] The spraying assembly includes a tube body, a filter element, and a nozzle. The two ends of the filter element are connected to the nozzle and the tube body, respectively, to form a spray channel for spraying bacterial liquid.

[0007] A cleaning assembly having a water inlet for discharging cleaning water, the water inlet being connected to the pipe body for allowing the cleaning water to flow along a spray channel; and

[0009] Furthermore, the cleaning component includes a first three-way valve and a water injection pipe. The first end of the first three-way valve is connected to the water injection end, and its second end is connected to the water injection pipe. The third end of the first three-way valve is connected to a bacterial liquid supply pipe, which is used to switch the connection between the pipe body and the water injection pipe or the connection between the pipe body and the bacterial liquid supply pipe.

[0010] Furthermore, the filter element includes a second three-way valve, a filter box, and a filter screen. The first end of the second three-way valve is connected to the pipe body, and the second end is connected to the filter box.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0029] like Figure 1-5As shown, this utility model provides a bacterial liquid spraying device, including a spraying component 1, a cleaning component 2, and a backflushing component 3. The spraying component 1 includes a pipe body 11, a filter element 12, and a nozzle 13. The two ends of the filter element 12 are respectively connected to the nozzle 13 and the pipe body 11, forming a spray channel for the bacterial liquid to be filtered and then sprayed out. The bacterial liquid supply pipe is connected to the pipe body 11, pressurizing and supplying bacterial liquid into the pipe body 11. The bacterial liquid flows through the pipe body 11 to each filter element 12 for filtration, and then enters the nozzle 13, from which it is sprayed into the fermentation tank for biomass fertilizer preparation, preventing suspended particles from clogging the nozzle 13. The cleaning component 2 has a function of discharging clean liquid. The water inlet 201 is located adjacent to the end of the tube 11 where the bacterial solution is supplied. The water inlet 201 is connected to and communicates with the tube 11, allowing clean water to flow along the spray channel. That is, pressurized clean water is injected, flows sequentially through the tube 11 and the nozzle 13, and flows out from the nozzle 13, rinsing along the spray channel to prevent bacterial solution from remaining in the tube 11 and the nozzle 13, thus reducing the probability of clogging. The backwash assembly 3 has a backwash end 301 for discharging backwash water. The backwash end 301 is connected between the nozzle 13 and the filter element 12, allowing backwash water to flow in the reverse direction to the filter element 12 to backwash the filter element 12 and prevent clogging.

[0030] Understandably, the spraying component 1 forms a bacterial liquid spraying channel for normal bacterial liquid spraying. After each batch of spraying is completed, the bacterial liquid spraying channel can be rinsed through the cleaning component 2 to avoid bacterial liquid residue. After rinsing, the filter element 12 can be backflushed through the backflushing component 3 to prevent excessive accumulation of filtered particles in the filter element 12. With the above structure in combination, the disassembly and replacement of the nozzle 13 can be effectively avoided, reducing the probability of replacement of parts due to blockage.

[0031] In one embodiment, to form a cleaning component 2 structure that allows for switching between bacterial solution and cleaning fluid flow channels, the cleaning component 2 includes a first three-way valve 21 and a water injection pipe 22. The first end of the first three-way valve 21 is connected to the water injection end 201, which is connected to and communicates with the pipe body 11. The second end of the first three-way valve 21 is connected to the water injection pipe 22, which is connected to a cleaning water source. The cleaning water source is pumped to supply cleaning water. The third end of the first three-way valve 21 is connected to a bacterial solution supply pipe 202, which is connected to a bacterial solution storage tank. The bacterial solution is pumped through the bacterial solution supply pipe 202. The first three-way valve 21 is used to switch the connection between the pipe body 11 and the water injection pipe 22 or the connection between the pipe body 11 and the bacterial liquid supply pipe 202. When the first end of the first three-way valve 21 is connected to the second end, the pipe body 11 is in cleaning mode, and cleaning water flows sequentially through the water injection pipe 22, the first three-way valve 21, the water injection end 201, the pipe body 11 and the nozzle 13 to form a flush. When the second end of the first three-way valve 21 is connected to the third end, the pipe body 11 is in bacterial liquid spraying mode, and bacterial liquid flows sequentially through the bacterial liquid supply pipe 202, the first three-way valve 21, the water injection end 201, the pipe body 11 and the nozzle 13 to form a spray.

[0032] In one embodiment, in order to achieve the filtration effect of suspended particles in the bacterial solution, the filter element 12 includes a second three-way valve 121, a filter box 122, and a filter screen 123. The first end of the second three-way valve 121 is connected to the pipe body 11, and the second end of the second three-way valve 121 is connected to the filter box 122. The filter screen 123 is inserted into the filter box 122. When the pipe body 11 is connected, the bacterial solution is filtered by the filter screen 123 before reaching the nozzle 13 and being sprayed out, which can prevent the suspension from clogging at the nozzle 13.

[0033] Understandably, the filter box 122 can adopt a detachable box structure. After the box is disassembled, the filter screen 123 is inserted into the inside of the filter box 122, and then it is reassembled and closed. One end of the box can be connected to the pipe body 11 through the second three-way valve 121, and the other end can be connected to the nozzle 13 through the third three-way valve 31.

[0034] Furthermore, to facilitate backflushing of the filter screen 123, the third end of the second three-way valve 121 is connected to a wastewater discharge pipe 302. The backflushing assembly 3 includes a third three-way valve 31 and a backflushing pipe 32. The first end of the third three-way valve 31 is connected to the backflushing pipe 32, and its second end is connected to the backflushing end 301, which is connected to the filter box 122. The third end of the third three-way valve 31 is connected to the nozzle 13. During backflushing, the third three-way valve 31 switches to a configuration where its second end is connected to its first end, and the second three-way valve 121 switches to a configuration where its third end is connected to its second end. Backflushing liquid is injected into the backflushing pipe 32, enters the filter box 122 to backflush the filter screen 123, and then discharges through the second three-way valve 121 and the wastewater discharge pipe 302.

[0035] Understandably, the waste liquid generated by backflushing is discharged through the waste liquid discharge pipe 302, which can avoid contamination of the pipe body 11 after rinsing.

[0036] In one embodiment, in order to achieve a wider coverage of bacterial liquid spraying, there are multiple nozzles 13, and the filter elements 12 are linearly arranged on the pipe body 11 in a one-to-one correspondence with the nozzles 13, wherein the filter elements 12, nozzles 13 and backwash components 3 are all in one-to-one correspondence.

[0037] Furthermore, a main sewage discharge pipe 303 is connected between the multiple sewage discharge pipes 302 to centrally discharge the sewage backwashed from each filter element 12, thereby enabling centralized collection of sewage.

[0038] In one embodiment, to prevent the flushing water from being discharged into the fermentation tank during rinsing and affecting the concentration ratio of biomass fertilizer, the bacterial liquid spraying device also includes a shut-off component 4. The shut-off component 4 has a liquid guide end 401, which is used to drive the liquid guide end 401 to move, so that it has a first position state in which the liquid guide end 401 covers and connects to the nozzle 13, and a second position state in which it is disconnected from the nozzle 13. The liquid guide end 401 is used to connect to the spray end of the nozzle 13 to guide and collect the flushing water.

[0039] Understandably, in the first position, the liquid guide end 401 blocks the nozzle 13, and the sprayed cleaning liquid can only flow through the liquid guide end 401, thus avoiding the direct discharge of the rinsing liquid into the fermentation tank; in the second position, the liquid guide end 401 is removed from the nozzle 13, the nozzle 13 is not blocked, and normal bacterial liquid spraying can be carried out.

[0040] Specifically, the opening and closing assembly 4 includes a linear drive mechanism 41 and a connecting pipe 42. The liquid guiding end 401 is disposed on the connecting pipe 42 and corresponds one-to-one with the nozzle 13. The movable end of the linear drive mechanism 41 is connected to the connecting pipe 42 and is used to drive the connecting pipe 42 to move, so that the liquid guiding end 401 switches between a first position state and a second position state. The connecting pipe 42 is connected to each liquid guiding end 401, and is used to flush the liquid guiding end 401 into the connecting pipe 42 and discharge it in a concentrated manner.

[0041] Understandably, the linear drive mechanism 41 can be an existing mature device with telescopic function, such as a hydraulic push rod, a lead screw guide pair, or a cylinder push rod.

[0042] Furthermore, the liquid guiding end 401 is connected to the front side of the connecting pipe 42, and the top of the liquid guiding end 401 is provided with an opening 402. By arranging them horizontally, the spray below the nozzle 13 is not blocked.

[0043] Furthermore, in order to improve the sealing effect, a sealing ring 403 is connected to the top of the liquid guiding end 401. When the sealing ring 403 is in the first position state, it abuts against the liquid spraying end of the nozzle 13, and the sealing ring 403 provides a seal between the nozzle 13 and the liquid guiding end 401 when the nozzle is in the first position state.

[0044] It should be noted that, for automated control, the entire device is also equipped with a PLC programmable controller. The first three-way valve 21, the second three-way valve 121, and the third three-way valve 31 are all solenoid valves and are electrically connected to the PLC programmable controller. The switching of the channels of the first three-way valve 21, the second three-way valve 121, and the third three-way valve 31 is controlled by the program to switch between spraying, flushing, and backflushing. The above control adopts existing conventional control methods, which will not be elaborated on here.

[0045] The specific working process of this utility model is as follows: When spraying bacterial liquid, the bacterial liquid supply pipe 202, the pipe body 11 and the nozzle 13 are connected to supply bacterial liquid for flow and spraying; when rinsing the pipe body 11 and the nozzle 13, the water injection pipe 22, the pipe body 11 and the nozzle 13 are connected to supply rinsing water for flow and discharge from the nozzle 13. The liquid discharged from the nozzle 13 enters the liquid guide end 401, and is collected and discharged in the connecting pipe 42; when backwashing the filter element 12, the backwash pipe 32, the filter box 122 and the sewage discharge pipe 302 are connected to supply backwash water into the filter box 122 to backwash the filter screen 123, and is discharged from the sewage discharge pipe 302, and is collected and discharged in the sewage discharge main pipe 303.

[0046] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
