A microbial fertilizer concentration device

Abstract

This invention relates to the field of fertilizer preparation, and more particularly to a microbial fertilizer concentration device. The invention provides a microbial fertilizer concentration device that can heat liquid microbial fertilizer more evenly, thereby better maintaining microbial activity, and can improve steam utilization. A microbial fertilizer concentration device includes a base plate, support rods, a protective shell, and a steam heating mechanism. Four support rods are fixedly connected to the upper side of the base plate, and the protective shell is fixedly connected to the upper side of the base plate. All four support rods are located inside the protective shell, and the steam heating mechanism is located between the four support rods. Steam then drives several blades, a slotted ring plate, and a perforated plate to rotate. Steam enters the perforated plate, causing the perforated plate to rotate around the outside of the concentration tank and discharge steam, allowing steam to evenly surround the outside of the concentration tank. This makes the liquid microbial fertilizer in the concentration tank more evenly heated, thereby more stably evaporating and concentrating the liquid microbial fertilizer, further maintaining the activity of the microbial fertilizer.

Description

Technical Field

[0001] This invention relates to the field of fertilizer preparation, and more particularly to a microbial fertilizer concentration device. Background Technology

[0002] Soil is mainly composed of three parts: minerals, organic matter, and microorganisms. The activity level of microorganisms in the soil microecological zone is very important for the nutrition of plant roots. However, the number of beneficial microorganisms is insufficient in a purely natural state. By artificially adding microbial fertilizers to the soil, the number of beneficial microorganisms can be effectively increased, thereby improving soil fertility. Therefore, microbial fertilizers play a very important role in agricultural production.

[0003] In the preparation of microbial fertilizer, further concentration is required to facilitate transportation and enhance fertilizer effectiveness. Since microbial fertilizer contains microorganisms, the liquid microbial fertilizer is generally concentrated by evaporation and low-temperature heating under reduced pressure to maintain their activity. However, as evaporation proceeds, the amount of liquid microbial fertilizer in the container gradually decreases, and it concentrates at the bottom of the container. Meanwhile, the steam rises within the container, concentrating at the top, resulting in uneven heating of the liquid microbial fertilizer. This leads to instability during concentration, which in turn reduces the activity of the microorganisms, ultimately resulting in poor concentration and low steam utilization, leading to low concentration efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of uneven heating of liquid microbial fertilizer and low steam utilization rate in the current evaporation and concentration of microbial fertilizer, the present invention provides a microbial fertilizer concentration device that can heat liquid microbial fertilizer more evenly, thereby better maintaining the activity of microorganisms, and can improve the utilization rate of steam.

[0005] The technical solution of the present invention is as follows: a microbial fertilizer concentration device, comprising a base plate, support rods, a protective shell, a steam heating mechanism and a concentration mechanism. Four support rods are fixedly connected to the side of the base plate, the protective shell is fixedly connected to the side of the base plate, and the four support rods are all located inside the protective shell. The steam heating mechanism is located between the four support rods, and the concentration mechanism is located on the steam heating mechanism.

[0006] As a preferred embodiment of the present invention, the steam heating mechanism includes an annular heating chamber, a steam generator, a bend, a straight pipe, a slotted air inlet block, round rods, an annular support plate, a return spring, and an L-shaped baffle. The annular heating chamber is fixedly connected to the upper ends of the four support rods. The steam generator is fixedly connected to the side of the base plate. The bend is fixedly connected to the outlet of the steam generator, and the straight pipe is fixedly connected to the inlet of the steam generator. Both the bend and the straight pipe are connected to the steam generator. The other end of the straight pipe is fixedly connected to the annular heating chamber, and the straight pipe is connected to the annular heating chamber. The slotted air inlet block is fixedly connected to the outer side of the annular heating chamber. The bend is fixedly connected to the slotted air inlet block. Three round rods are fixedly connected to the bottom of the annular heating chamber. An annular support plate is slidably connected between the three round rods. Three return springs are connected between the annular support plate and the annular heating chamber. The return springs are sleeved on the round rods. The L-shaped baffle is fixedly connected to the annular support plate and slidably connected to the slotted air inlet block.

[0007] As a preferred embodiment of the present invention, the concentration mechanism includes a concentration tank, an inlet pipe, a first valve, a second outlet pipe, a third valve, and a vacuum pump. The concentration tank is slidably connected to an annular heating chamber. The inlet pipe is fixed to the upper part of the concentration tank and communicates with it, passing through a protective shell. The first valve is located on the inlet pipe. The second outlet pipe is fixed to the bottom of the concentration tank and passes through the protective shell. The third valve is located on the second outlet pipe. The vacuum pump is fixed to the top of the concentration tank and communicates with it, passing through the protective shell.

[0008] As a preferred embodiment of the present invention, it further includes a gas guiding mechanism, which is disposed on the annular heating chamber. The gas guiding mechanism includes a slotted ring plate, a perforated plate, blades, and an inclined gas guide grid. The slotted ring plate is slidably connected to the upper part of the annular heating chamber. The perforated plate is fixed to the bottom of the slotted ring plate and has several through holes. Several blades are fixed to the side of the slotted ring plate away from the concentration tank. The inclined gas guide grid is fixed to the side of the annular heating chamber near the slotted air inlet block.

[0009] As a preferred embodiment of the present invention, it further includes a gas-saving mechanism, which is disposed inside the concentration tank and connected to the annular heating chamber. The gas-saving mechanism includes an annular pressure rod, a float plate, a small baffle, and two return springs. The annular pressure rod is slidably connected inside the concentration tank and slidably connected to the annular heating chamber. The float plate is fixed to one end of the annular pressure rod and is located inside the concentration tank. The small baffle is fixed to the other end of the annular pressure rod and slidably connected to the slotted annular plate. Two return springs are connected between the small baffle and the slotted annular plate. The small baffle is also slidably connected to the perforated plate.

[0010] As a preferred embodiment of the present invention, it further includes an arc-shaped scraper, which is fixedly connected to the bottom of the slotted ring plate and contacts the inner wall of the annular heating chamber.

[0011] As a preferred embodiment of the present invention, a heating ring is also included, which is fixedly attached to the upper side of the top of the concentration tank.

[0012] Beneficial effects:

[0013] 1. First, the worker opens valve one and then injects the liquid microbial fertilizer into the concentration tank through the feed pipe. The L-shaped baffle will move downward and no longer block the slotted air inlet block. Next, the worker starts the vacuum pump, which will create a vacuum inside the concentration tank, reducing the pressure inside the tank and lowering the boiling point of the liquid microbial fertilizer. Then, the worker starts the steam generator, and the steam will enter the annular heating chamber. The annular heating chamber will transfer the heat of the steam to the concentration tank, causing the liquid microbial fertilizer in the tank to evaporate and concentrate at a low temperature. At the same time, the concentrated microbial fertilizer retains its activity, resulting in a better concentration effect.

[0014] 2. The inclined air guide grille guides the steam, which then drives several blades, slotted ring plates, and perforated plates to rotate. The steam enters the perforated plates and is then discharged into the annular heating chamber through the through holes on the perforated plates. This causes the perforated plates to rotate around the outside of the concentration tank and discharge steam, allowing the steam to evenly surround the outside of the concentration tank. This makes the liquid microbial fertilizer in the concentration tank more evenly heated, thus evaporating and concentrating the liquid microbial fertilizer more stably and further maintaining the activity of the microbial fertilizer.

[0015] 3. As the liquid microbial fertilizer in the concentration tank evaporates and concentrates, the amount of liquid microbial fertilizer in the concentration tank will decrease. The float plate and small baffle will move downward under the action of gravity. The small baffle will gradually block the through holes at the top of the perforated plate, so that the steam is concentrated and discharged through several through holes at the bottom of the perforated plate. In this way, when the liquid microbial fertilizer is in the concentration tank, the steam is concentrated in the lower part of the annular heating chamber, which further concentrates the evaporation and concentration of the liquid microbial fertilizer in the concentration tank, improves the utilization rate of steam, and thus improves the concentration efficiency while reducing steam waste.

[0016] 4. The inner wall of the annular heating chamber is scraped by an arc-shaped scraper to remove small water droplets, reducing the impact of water droplets on steam heat conduction. This allows the steam in the annular heating chamber to conduct heat more evenly to the concentration tank, resulting in more uniform heating of the liquid bacterial fertilizer.

Detailed Implementation

[0032] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art, and will not be described in detail here.

[0033] Example 1

[0034] A device for concentrating microbial fertilizer, such as Figures 1-10 As shown, it includes a base plate 101, support rods 102, a protective shell 2, a steam heating mechanism, and a concentration mechanism. Four support rods 102 are welded to the upper side of the base plate 101. The protective shell 2 is bolted to the upper side of the base plate 101. All four support rods 102 are located inside the protective shell 2. The steam heating mechanism is located between the four support rods 102 and is used to heat the liquid microbial fertilizer at low temperature. The concentration mechanism is located on the steam heating mechanism and is used to concentrate the liquid microbial fertilizer.

[0035] The steam heating mechanism includes an annular heating chamber 31, a steam generator 32, a bend 321, a straight pipe 322, a slotted air inlet block 323, a round rod 33, an annular support plate 34, a return spring 35, and an L-shaped baffle 36. The annular heating chamber 31 is welded between the upper ends of the four support rods 102. The steam generator 32 is riveted to the upper side of the base plate 101. The bend 321 is connected to the air outlet of the steam generator 32 via a flange and is used to transport steam. The straight pipe 322 is fixed to the air inlet of the steam generator 32. Both the bend 321 and the straight pipe 322 are connected to the steam generator 32. The other end of the tube 22 is fixedly connected to the annular heating chamber 31, and the straight tube 322 is connected to the annular heating chamber 31. The slotted air inlet block 323 is bolted to the outer side of the annular heating chamber 31. The bent tube 321 is fixedly connected to the slotted air inlet block 323. Three round rods 33 are welded to the bottom of the annular heating chamber 31. An annular support plate 34 is slidably connected between the three round rods 33. Three return springs 35 are connected between the annular support plate 34 and the annular heating chamber 31 through hooks. The return springs 35 are sleeved on the round rods 33. The L-shaped baffle 36 is welded to the annular support plate 34. The L-shaped baffle 36 is slidably connected to the slotted air inlet block 323.

[0036] The concentration mechanism includes a concentration tank 41, an inlet pipe 42, a first valve 43, an outlet bend 44, a second valve 45, and a vacuum pump 46. The concentration tank 41 is slidably connected to the annular heating chamber 31 and is located above the annular support plate 34. The inlet pipe 42 is fixed to the upper part of the concentration tank 41 and communicates with it, passing through the protective shell 2. The first valve 43 is located on the inlet pipe 42. The outlet bend 44 is fixed to the bottom of the concentration tank 41 and passes through the protective shell 2. The outlet bend 44 is used to discharge the microbial fertilizer. The second valve 45 is located on the outlet bend 44. The vacuum pump 46 is bolted to the top of the concentration tank 41 and communicates with it, passing through the protective shell 2. The vacuum pump 46 is used to evacuate the inside of the concentration tank 41.

[0037] First, the worker opens valve 43 and then injects liquid microbial fertilizer into the concentration tank 41 through the feed pipe 42. Under gravity, the concentration tank 41 pushes the annular support plate 34 and L-shaped baffle 36 downwards. The L-shaped baffle 36, now lowered, no longer blocks the slotted air inlet block 323. Next, the worker starts the vacuum pump 46, which creates a vacuum inside the concentration tank 41, reducing the pressure and lowering the boiling point of the liquid microbial fertilizer. Then, the worker starts the steam generator 32, which produces steam. The steam flows through the bend pipe 321 to the slotted air inlet block 323 and then into the annular heating chamber 31. The annular heating chamber 31 then heats the steam... Heat is conducted to the concentration tank 41, causing the liquid microbial fertilizer inside to evaporate and concentrate at a low temperature. This also keeps the concentrated microbial fertilizer active, resulting in better concentration. The steam in the annular heating chamber 31 is discharged through the straight pipe 322 and flows back into the steam generator 32, thus enabling the steam to be recovered and reused. After concentration, the worker turns off the vacuum pump 46 and the steam generator 32, and then opens the valve 45. The microbial fertilizer in the concentration tank 41 is discharged through the discharge bend 44, reducing the mass of the concentration tank 41. The return spring 35 resets and drives the annular support plate 34, the L-shaped baffle 36, and the concentration tank 41 to reset upwards. The L-shaped baffle 36 then blocks the slotted air inlet block 323 again.

[0038] Example 2

[0039] Based on Example 1, such as Figures 10-14As shown, it also includes a gas guiding mechanism, which is located on the annular heating chamber. The gas guiding mechanism is used to guide the steam, so that the liquid bacterial fertilizer in the concentration tank 41 is heated more evenly. The gas guiding mechanism includes a slotted ring plate 51, an orifice plate 52, blades 53 and an oblique gas guide grid 54. The slotted ring plate 51 is slidably connected to the upper part of the annular heating chamber 31. The orifice plate 52 is welded to the bottom of the slotted ring plate 51. The orifice plate 52 has several through holes. Several blades 53 are welded to the side of the slotted ring plate 51 away from the concentration tank 41. The oblique gas guide grid 54 is fixed to the side of the annular heating chamber 31 near the slotted air inlet block 323. The oblique gas guide grid 54 is used to guide the steam.

[0040] When steam flows through bend 321 to slotted air inlet block 323, it passes through inclined guide grille 54, which guides the steam. The steam then enters perforated plate 52 and exits through through holes in perforated plate 52 into annular heating chamber 31. Simultaneously, the steam drives several blades 53, slotted ring plate 51, and perforated plate 52 to rotate, causing perforated plate 52 to rotate around the outside of concentration tank 41 and discharge steam. This allows the steam to evenly surround the outside of concentration tank 41, making the liquid microbial fertilizer in concentration tank 41 more evenly heated, thus evaporating and concentrating the liquid microbial fertilizer more stably and further maintaining the activity of the microbial fertilizer.

[0041] Example 3

[0042] Based on Example 2, such as Figure 5 and Figure 14 As shown, it also includes a steam-saving mechanism, which is located inside the concentration tank 41 and connected to the annular heating chamber 31. The steam-saving mechanism is used to improve the utilization rate of steam, thereby improving the concentration efficiency while reducing steam waste. The steam-saving mechanism includes an annular pressure rod 61, a float plate 62, a small baffle 63, and a second return spring 64. The annular pressure rod 61 is slidably connected inside the concentration tank 41 and to the annular heating chamber 31. The annular pressure rod 61 has an n-shaped structure. The float plate 62 is welded to one end of the annular pressure rod 61 and is located inside the concentration tank 41. The small baffle 63 is welded to the other end of the annular pressure rod 61 and is slidably connected to the slotted annular plate 51. Two second return springs 64 are connected between the small baffle 63 and the slotted annular plate 51. The small baffle 63 is also slidably connected to the perforated plate 52 and is used to block the through holes on the perforated plate 52.

[0043] When liquid microbial fertilizer is introduced into the concentration tank 41, the amount of liquid microbial fertilizer in the concentration tank 41 gradually increases. The float plate 62 comes into contact with the liquid microbial fertilizer in the concentration tank 41, and the float plate 62 moves upward under the action of buoyancy. The upward movement of the float plate 62 drives the small baffle 63 to move upward. The small baffle 63 no longer blocks the through holes on the perforated plate 52. As the liquid microbial fertilizer in the concentration tank 41 evaporates and concentrates, the amount of liquid microbial fertilizer in the concentration tank 41 decreases. The float plate 62 and the small baffle 63 move downward under the action of gravity. The small baffle 63 gradually blocks the through holes in the upper part of the perforated plate 52, so that the steam is concentrated and discharged through several through holes in the lower part of the perforated plate 52. Thus, when liquid microbial fertilizer is in the concentration tank 41, the steam is concentrated in the lower part of the annular heating chamber 31, thereby evaporating and concentrating the liquid microbial fertilizer in the concentration tank 41 more concentratedly, improving the steam utilization rate, thereby improving the concentration efficiency while reducing steam waste.

[0044] Example 4

[0045] Based on Example 1, such as Figure 5 and Figure 6 As shown, it also includes an arc-shaped scraper 7, which is welded to the bottom of the slotted ring plate 51. The arc-shaped scraper 7 is in contact with the inner wall of the annular heating chamber 31 and is used to scrape off the water from the inner wall of the annular heating chamber 31.

[0046] Steam condenses into small water droplets on the inner wall of the annular heating chamber 31. When the slotted ring plate 51 rotates, it drives the arc-shaped scraper 7 to rotate. The arc-shaped scraper 7 scrapes the inner wall of the annular heating chamber 31, thereby removing the small water droplets and reducing the impact of the small water droplets on the heat conduction of the steam. This allows the steam in the annular heating chamber 31 to conduct heat to the concentration tank 41 more evenly, making the liquid bacterial fertilizer more evenly heated. The water removed will flow back into the steam generator 32 through the straight pipe 322 for evaporation.

[0047] Example 5

[0048] Based on Example 1, such as Figure 4 and Figure 5 As shown, it also includes a heating ring 8, which is fixed to the upper side of the top of the concentration tank 41 and is used to heat the top of the concentration tank 41.

[0049] When the steam generator 32 is started, the heating ring 8 is also started. The heating inside the concentration tank 41 generates steam. The steam comes into contact with the top of the concentration tank 41, and the heating ring 8 heats the top of the concentration tank 41, causing the temperature of the top of the concentration tank 41 to rise. The contact between the steam and the high temperature of the top of the concentration tank 41 can reduce the condensation of steam into water, thereby reducing the amount of water dripping into the bacterial fertilizer inside the concentration tank 41, and thus better evaporating and concentrating the liquid bacterial fertilizer.
