Description

Technical Field

[0001] The present invention relates to the technical field of organic waste treatment, in particular to a waste biochemical treatment machine and a decanter thereof. Background Art

[0002] When using aerobic fermentation biological treatment process to treat food waste, the moisture content of the material is required to be controlled at 55%±5%. However, the food waste actually loaded into the biochemical treatment machine, although dehydrated, still has a moisture content of more than 80% to 85%.

[0003] During the three processes of heating, fermentation and initial drying, the material will produce some free water in the form of leachate due to mechanical stirring, salt penetration, fermentation and other factors. If this leachate is not discharged in time, it will take energy and time to convert it into steam for evaporation and drying, which increases the working energy consumption of the biochemical treatment machine and prolongs the process time. In addition, more importantly, this leachate has high salt and oil content. If this leachate is not discharged in time, it will affect the product quality of the biochemical treatment machine.

[0004] However, most of the decanters on the market are equipment used in sewage treatment processes and water grates commonly used in daily life. Water grates only have decanting functions but no self-cleaning functions, and the decanting holes (slits) are easily clogged. These products are not suitable for garbage biochemical treatment machines in terms of structure or working principle.

[0005] Therefore, how to provide a decanter to reduce the working energy consumption of the organic waste biochemical treatment machine is an urgent problem to be solved by people in this technical field. Summary of the Invention

For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0026] Figure 2 This is a schematic diagram of the second structure of the decanter disclosed in the embodiment of the present invention. DETAILED DESCRIPTION

[0027] The invention discloses a decanter for a biochemical garbage treatment machine, which reduces the working energy consumption of the biochemical organic garbage treatment machine. In addition, the invention also discloses a biochemical garbage treatment machine with the decanter.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, the present application discloses a decanter installed at the bottom of a storage chamber 7 , which includes a valve body 1 , a static decanting tray 3 , a dynamic decanting tray 2 and a control component.

[0030] The valve body 1 serves as the structural foundation of the entire decanter, mounted at the bottom of the storage chamber 7. It includes a leachate channel and a leachate outlet 5 connected to the channel. The shape and dimensions of the valve body 1 are not limited. Preferably, the valve body 1 is cylindrical with the leachate channel in the center. The connection between the valve body 1 and the storage chamber 7 and the mounting arrangement can be customized to meet specific needs.

[0031] The static decanting tray 3 is disposed at one end of the leachate channel, preferably near the stirring end, and has a decanting hole that connects the storage chamber 7 and the leachate channel. The decanting hole allows the leachate generated in the storage chamber to be discharged into the decanter. Therefore, the size and shape of the decanting hole are not limited, as long as the structure can meet the above requirements.

[0032] The aforementioned movable decanter 2 is disposed within the leachate channel and is capable of axial movement along the leachate channel. During use, the material within the storage chamber 7, under the axial extrusion force of the stirring screw or impeller and the weight of the material, generates axial pressure on the decanter. This causes the movable decanter 2 to axially move away from the static decanter 3, allowing the leachate to flow through the decanting holes of the static decanter 3, into the gap between the two, and ultimately out of the leachate discharge port 5. In other words, the leachate is discharged by moving the movable decanter 2 away from the static decanter 3, while the sealing is achieved by the contact between the movable decanter 2 and the static decanter 3.

[0033] The control member is used to control the distance between the movable decanter tray 2 and the static decanter tray 3. By providing the control member, the decanter can be automatically controlled without manual operation, thereby improving the usability of the device.

[0034] By adding a decanter to the garbage biochemical treatment machine, the garbage biochemical treatment machine can have a decanting function, reduce the working energy consumption of the biochemical treatment machine, shorten the process time, and more importantly, ensure the product quality of the biochemical treatment machine.

[0035] In a specific embodiment, the valve body 1 of the decanter is fixed to the bottom outer wall of the storage chamber 7 by bolts. This discloses one connection method and location for the decanter. Those skilled in the art will appreciate that the valve body 1 and the storage chamber 7 may also be connected by snapping or bonding. To minimize leachate in the storage chamber 7, the decanter may be positioned at the bottom side of the storage chamber 7 or on the bottom surface of the storage chamber 7.

[0036] In a preferred embodiment, the static decanter tray 3 is fixed to the end of the leachate channel and is sealed to the inner wall of the leachate channel. In summary, the static decanter tray 3 not only seals the decanter but also connects the decanter to the storage chamber 7. Sealing the static decanter tray 3 from the leachate channel prevents backflow of liquid within the leachate channel.

[0037] In a specific embodiment, the control member is a pulsating return spring 4, and the pulsating return spring 4 connects the static decanter 3 and the dynamic decanter 2. Specifically, since the axial extrusion force of the stirring screw is pulsating and the direction is alternating, therefore, during operation:

[0038] When the material in storage chamber 7 is squeezed by the axial pressure of the stirring screw (or blade) and gravity, the resulting leachate flows into the decanting hole of static decanter 3, overcoming the preload of pulsating return spring 4 to push open dynamic decanter 2. The leachate then flows through the gap between the interface of static decanter 3 and dynamic decanter 2 to the leachate discharge port 5 of the decanter. When the axial pressure reverses, dynamic decanter 2 is depressurized, and the pulsating return spring 4 resets the dynamic decanter 2. During this process, the dynamic decanter 2 exerts a reverse force on the leachate in the decanting hole, causing it to flow in the opposite direction. This arrangement ensures self-cleaning of the decanting hole, prevents clogging, and promptly discharges leachate from storage chamber 7, reducing energy consumption, shortening process time, and improving product quality.

[0039] To accommodate varying extrusion forces and gravity, the valve body 1 of the present invention is provided with an adjustment handle 6 at one end, away from the storage chamber 7, for adjusting the elastic force of the pulsating return spring 4. By providing the adjustment handle 6, the elastic force of the pulsating return spring 4 can be varied to accommodate varying requirements, thereby expanding the applicability of the decanter.

[0040] Specifically, the adjustment handle 6 is threadedly connected to the inner wall of the leachate channel. This threaded connection allows the adjustment handle 6 to rotate, adjusting the compression of the pulsation return spring 4 during rotation, thereby adjusting the elastic force of the pulsation return spring 4. Furthermore, the threaded connection ensures a tight seal between the adjustment handle 6 and the leachate channel, preventing leachate from contaminating the adjustment handle 6. The adjustment handle 6 can be an adjustment rod structure, and in practice, the adjustment handle 6 can also be configured to move relative to the axis of the leachate channel.

[0041] In another embodiment, Figure 2 As shown, the control element can also be an electromagnetic control assembly 8, and the electromagnetic control assembly 8 is used to control the movement of the dynamic decanting pan 2. When the electromagnetic control assembly 8 is energized, the dynamic decanting pan 2 and the static decanting pan 3 move away from each other; when the electromagnetic control assembly 8 is deenergized, the dynamic decanting pan 2 and the static decanting pan 3 fit together. That is, the dynamic decanting pan 2 and the electromagnetic control assembly form a solenoid valve structure. Through the above-mentioned setting, the gap between the dynamic decanting pan 2 and the static decanting pan 3 is opened and closed, completing the control process. In addition, during the control process of the electromagnetic control assembly, when the dynamic decanting pan 2 moves in the opposite direction toward the static decanting pan 3, the dynamic decanting pan 2 can also achieve a reverse force on the leachate in the decanting hole, causing the leachate to flow in the opposite direction, achieving self-cleaning of the decanting hole, preventing blockage, and timely discharging the leachate from the storage chamber 7, thereby reducing energy consumption, shortening process time, and improving product quality.

[0042] The leachate discharge port 5 disclosed in this application is a threaded quick-change connector. A specific structure of the leachate discharge port 7 is disclosed herein. In practice, other structures can also be selected as the structure of the leachate discharge port 7 and are all within the scope of protection.

[0043] Specifically, the leachate discharge port 7 is arranged in the middle part of the leachate channel along the axial direction, that is, the specific position of the leachate discharge port 7 is defined here, but the leachate discharge port 7 in this solution is not limited thereto.

[0044] In addition, the present application also discloses a garbage biochemical treatment machine, which includes a decanter as disclosed in the above embodiment. Therefore, the garbage biochemical treatment machine with the decanter also has all the above technical effects, which will not be described one by one here.

[0045] In practice, the decanter can also be used in organic waste wet material storage bins, that is, in other equipment that requires decanting, and all are within the scope of protection.

[0046] In practice, the effect of the biochemical treatment machine using the decanter disclosed in this solution is illustrated by taking the following example:

[0047] For example, a GS7500 biochemical treatment unit equipped with two BSQ-DN50 pulsating decanters handles 5,500 kg of food waste with an 80% moisture content per shift. During the warming, fermentation, and initial drying processes, 4% of the leachate, or 220 kg, is discharged from the decanters. Based on the GS7500 biochemical treatment unit's actual steam consumption of 0.4 tons of fresh steam per ton of water, evaporating and drying 220 kg of leachate consumes 88 kg of steam. Based on a 330-shift production schedule, this saves 29 tons of steam annually.

[0048] The cost of a DN50-d5 pulsating decanter is no more than 500 yuan, and its design service life is 5 years.

[0049] Based on the steam price of RMB 260 per ton, a GS75OO biochemical treatment machine can save RMB 7,540 in steam costs each year.

[0050] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0051] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
