[0024] Combine the following Figure 1 , through specific embodiments and application scenarios, an environmentally friendly enzyme mixed fermentation liquid filtration device provided by the embodiment of the utility model is described in detail.

[0025] The utility model provides an environmentally friendly enzyme mixed fermentation liquid filtration device, comprising: a fermentation tank 1, a filter screen 2, a delivery pipe 3 and a liquid storage tank 4. The fermentation tank 1 is used to contain the environmentally friendly enzyme mixed fermentation liquid. The filter screen 2 can be raised and lowered inside the fermentation tank 1, so that at least part of the filter screen 2 is immersed in the environmentally friendly enzyme mixed fermentation liquid. The filter screen 2 divides the fermentation tank 1 into a filtered area and an unfiltered area, the liquid inlet end of the delivery pipe 3 is located in the filtered area, and the liquid outlet end of the delivery pipe 3 is connected to the inside of the liquid storage tank 4.

[0026] It is understandable that the environmentally friendly enzyme mixed fermentation liquid filtration device provided by the utility model, the fermentation tank 1 is used to store fruit and vegetable waste, etc., and after a period of fermentation, an environmentally friendly enzyme mixed fermentation liquid is generated in the fermentation tank 1. Generally, solid waste such as fermented fruit and vegetable residues is deposited at the bottom of the fermentation tank due to gravity, and the environmentally friendly enzyme mixed fermentation liquid is located on the upper layer.

[0027] At least part of the filter screen 2 is immersed in the environmentally friendly enzyme mixed fermentation liquid, dividing the cavity of the fermentation tank 1 into a filtering area and a non-filtering area. It should be noted that the utility model does not specifically limit the shape of the filter screen 2. The filter screen 2 can be barrel-shaped or sheet-shaped. When the filter screen 2 is sheet-shaped, the outer edge of the filter screen 2 contacts the peripheral wall of the fermentation tank 1 to divide the environmentally friendly enzyme mixed fermentation liquid into two layers, the lower layer is the unfiltered environmentally friendly enzyme mixed fermentation liquid, and the upper layer is the filtered environmentally friendly enzyme mixed fermentation liquid.

[0028] The liquid inlet end of the delivery pipe 3 is located in the filtration area. The liquid outlet end of the delivery pipe 3 is inserted into the liquid storage tank 4. Thus, the environmentally friendly enzyme mixed fermentation liquid in the fermentation tank 1 filters solid waste such as fruit and vegetable residues through the filter net 2, and then the environmentally friendly enzyme mixed fermentation liquid is pumped into the liquid storage tank 4 through the delivery pipe 3 for storage.

[0029] Optionally, the delivery pipe 3 may be a PE pipe.

[0030] When the delivery pipe 3 gradually pumps the environmentally friendly enzyme mixed fermentation liquid into the liquid storage tank 4, the liquid level in the fermentation tank 1 gradually decreases. The filter screen 2 is arranged inside the fermentation tank 1 in a liftable manner, which can ensure that the filter screen 2 can always be immersed in the environmentally friendly enzyme mixed fermentation liquid. The filter screen 2 is always located on the upper layer of the environmentally friendly enzyme mixed fermentation liquid, and the filter hole is not easily blocked, which is convenient to clean.

[0031] The utility model provides an environmentally friendly enzyme mixed fermentation liquid suction filtration device, a fermentation tank 1 is used to contain the environmentally friendly enzyme mixed fermentation liquid, a filter screen 2 divides the fermentation tank 1 into a filtering area and an unfiltered area, a liquid inlet end of a delivery pipe 3 is located in the filtering area, and a liquid outlet end of the delivery pipe 3 is connected to the inside of a liquid storage tank 4, so that the environmentally friendly enzyme mixed fermentation liquid in the fermentation tank 1 is filtered through the filter screen 2 and then directly delivered to the liquid storage tank 4 by the delivery pipe 3 for storage, the filter screen 2 can be raised and lowered inside the fermentation tank 1, as the liquid level in the fermentation tank 1 decreases, at least a portion of the filter screen 2 can always be immersed in the environmentally friendly enzyme mixed fermentation liquid, the environmentally friendly enzyme mixed fermentation liquid can be filtered thoroughly, the filtering effect is good, the filter screen 2 is not easy to be blocked, and the cleaning is convenient.

[0032] Specifically, Figure 1 As shown, the environmentally friendly enzyme mixed fermentation liquid filtration device also includes a plurality of rods. The rods extend along the axial direction of the fermentation tank 1. The plurality of rods are connected in sequence, and two adjacent rods are nested with each other to form a telescopic rod 5. One end of the telescopic rod 5 is fixedly connected to the inner wall of the fermentation tank 1, and the other end is fixedly connected to the filter screen 2.

[0033] It is understandable that the rod body is made of stainless steel. Each rod body is arranged vertically. Multiple rod bodies are connected in sequence and nested with each other to form a telescopic rod 5 with adjustable length. One end of the telescopic rod 5 is fixed to the inner wall of the fermentation tank 1, and the other end is telescopic. The telescopic end of the telescopic rod 5 is connected to the top of the filter screen 2 to drive the filter screen 2 to rise or fall in the cavity of the fermentation tank 1.

[0034] Optionally, the shortest length of the telescopic rod 5 is 20 cm. The stretching length of the telescopic rod 5 and the number of sections of the rod body can be adjusted according to the height of the fermentation tank 1 to meet the filtration requirements of the environmentally friendly enzyme mixed fermentation liquid.

[0035] Furthermore, if Figure 1 As shown, in some embodiments, a hook 51 is provided at one end of the telescopic rod 5 away from the filter screen 2. The hook 51 is fixedly connected to the telescopic rod 5. Optionally, the hook 51 and the telescopic rod 5 are an integral connection structure. The hook 51 is hung on the tank mouth of the fermentation tank 1 to provide support for the telescopic rod 5.

[0036] When in use, the hook 51 is hung on the tank mouth of the fermentation tank 1, and then the telescopic rod 5 is manually extended to a certain length so that at least part of the filter screen 2 is immersed in the environmentally friendly enzyme mixed fermentation liquid. After the delivery pipe 3 delivers a part of the environmentally friendly enzyme mixed fermentation liquid to the liquid storage tank 4, the liquid level of the environmentally friendly enzyme mixed fermentation liquid in the fermentation tank 1 becomes low. When the filter screen 2 is not immersed in the environmentally friendly enzyme mixed fermentation liquid, the telescopic rod 5 is continued to be manually extended to ensure that during the entire delivery process of the delivery pipe 3, at least part of the filter screen 2 can always be immersed in the environmentally friendly enzyme mixed fermentation liquid.

[0037] In other embodiments, the environmentally friendly enzyme mixed fermentation liquid filtration device further comprises an electric push rod. The extension direction of the electric push rod is arranged parallel to the axial direction of the fermentation tank 1. The electric push rod is fixed to the inner wall of the fermentation tank 1, and the telescopic end of the electric push rod is connected to the filter screen 2.

[0038] It is understandable that in this embodiment, the electric push rod includes a drive motor, a screw transmission mechanism and a rod body. The output end of the drive motor is connected to the screw of the screw transmission mechanism, the screw nut of the screw transmission mechanism is connected to the rod body, and the rod body is connected to the filter screen 2. The drive motor drives the screw transmission mechanism to operate, and the screw transmission mechanism drives the rod body to perform linear motion, thereby realizing the rise and fall of the filter screen 2.

[0039] In some embodiments, the filter screen 2 is barrel-shaped, the opening of the filter screen 2 faces upward, and the liquid inlet end of the delivery pipe 3 is accommodated in the cavity of the filter screen 2.

[0040] It is understandable that in this embodiment, the filter screen 2 is barrel-shaped. Among them, the filter screen 2 includes a bracket and a plurality of connecting rods. The bracket is barrel-shaped. The connecting rods are welded to the bracket. The plurality of connecting rods are arranged at intervals along the circumference of the bracket, so as to form a filter hole between two adjacent connecting rods. The opening of the filter screen 2 faces upward. When filtering the environmentally friendly enzyme mixed fermentation liquid, at least ensure that the bottom of the filter screen 2 is immersed in the environmentally friendly enzyme mixed fermentation liquid. Fruit and vegetable residues are isolated in the non-filtered area when passing through the filter hole, and the relatively pure environmentally friendly enzyme mixed fermentation liquid passes through the filter hole and is pumped by the delivery pipe 3 to the liquid storage tank 4 for storage, which is convenient for users to use.

[0041] Optionally, the filter screen 2 has a height of 30 cm and a diameter of 15 cm.

[0042] In some embodiments, the mesh size of the filter screen 2 is 58-62 meshes.

[0043] The higher the mesh number of the filter 2, the smaller the filter hole of the filter 2, and the finer the filtering effect. Setting the mesh number of the filter 2 to between 58 and 62 meshes can effectively filter out large and small particle residues in the environmentally friendly enzyme mixed fermentation liquid.

[0044] Preferably, the mesh number of the filter screen 2 is 60 meshes.

[0045] In some embodiments, optionally, the filter screen 2 is a glass fiber filter cartridge.

[0046] It is understood that the glass fiber filter cartridge is made of glass fiber, and using glass fiber as a filter medium can filter and separate the residue in the mixed fermentation liquid of the environmentally friendly enzyme. The glass fiber filter cartridge is in the shape of a long cylinder, and is filled with glass fiber or glass fiber fabric. These fibers can be in different structural forms, such as rope, mesh or tightly woven, to improve the filtering effect.

[0047] When the environmentally friendly enzyme mixed fermentation liquid passes through the glass fiber filter cartridge, the residue is blocked on the outside of the glass fiber filter cartridge, while the relatively pure environmentally friendly enzyme mixed fermentation liquid is discharged through the pores of the glass fiber filter cartridge.

[0048] Furthermore, if Figure 1 As shown, in some embodiments, the environmentally friendly enzyme mixed fermentation liquid filtration device further includes a regulating valve 6. The regulating valve 6 is arranged on the delivery pipe 3.

[0049] It is understandable that the regulating valve 6 may be a manual valve, so that the user can control the opening and closing of the delivery pipe 3 by manually twisting the manual valve.

[0050] Furthermore, if Figure 1 As shown, in some embodiments, the environmentally friendly enzyme mixed fermentation liquid filtration device also includes a controller and a liquid pump 7. The liquid pump 7 is arranged in the delivery pipe 3, and the regulating valve 6 and the liquid pump 7 are both electrically connected to the controller.

[0051] It is understandable that, in this embodiment, the regulating valve 6 can also be an electromagnetic switch valve. The electromagnetic switch valve is used to control the opening and closing of the delivery pipe 3. The controller is electrically connected to the electromagnetic switch valve, and can control the opening or closing of the electromagnetic switch valve, so as to facilitate the user to control the flow rate of the environmentally friendly enzyme mixed fermentation liquid sucked into the liquid storage tank 4.

[0052] Furthermore, the controller is electrically connected to the liquid pump 7, and can control the working state of the liquid pump 7, thereby controlling the liquid pump 7 to pump the environmentally friendly enzyme mixed fermentation liquid from the fermentation tank 1 to the delivery pipe 3 and discharge it into the liquid storage tank 4 from the liquid outlet end of the delivery pipe 3. The controller can adaptively adjust the suction force of the liquid pump 7. For example, when the volume of the environmentally friendly enzyme mixed fermentation liquid in the fermentation tank 1 is small, the controller is used to increase the suction force of the liquid pump 7 to ensure that the environmentally friendly enzyme mixed fermentation liquid can enter the delivery pipe 3.

[0053] Optionally, the liquid pump 7 can be a 15W self-priming water pump.

[0054] In some embodiments, Figure 1As shown, the environmentally friendly enzyme mixed fermentation liquid filtration device also includes a liquid level sensor 8 and an alarm 9. The liquid level sensor 8 is fixed to the inner wall of the liquid storage tank 4 and is used to monitor the liquid level of the environmentally friendly enzyme mixed fermentation liquid in the liquid storage tank 4. The liquid level sensor 8 and the alarm 9 are electrically connected to the controller respectively.

[0055] It is understandable that the liquid level sensor 8 is installed at the top of the liquid storage tank 4, that is, the position where the highest liquid level of the liquid storage tank 4 is located. The liquid level sensor 8 is used to monitor the liquid level of the environmentally friendly enzyme mixed fermentation liquid in the liquid storage tank 4. The liquid level sensor 8 can detect whether the liquid level of the environmentally friendly enzyme mixed fermentation liquid in the liquid storage tank 4 is higher than the preset highest liquid level.

[0056] The alarm 9 can be installed on the outer wall of the liquid storage tank 4. The liquid level sensor 8 is electrically connected to the controller, and the controller is electrically connected to the alarm 9. When the environmentally friendly enzyme mixed fermentation liquid immerses the liquid level sensor 8, which means that the liquid level of the environmentally friendly enzyme mixed fermentation liquid in the liquid storage tank 4 reaches the highest liquid level, the controller controls the alarm 9 to sound an alarm to prompt the user to stop injecting the environmentally friendly enzyme mixed fermentation liquid into the liquid storage tank 4. At the same time, the controller is electrically connected to the liquid pump 7 and the regulating valve 6. When the liquid level sensor 8 detects that the liquid level of the environmentally friendly enzyme mixed fermentation liquid in the liquid storage tank 4 has reached the highest liquid level, the controller controls the liquid pump 7 and the regulating valve 6 to close at the same time.

[0057] Optionally, the alarm 9 is a buzzer.

[0058] Furthermore, the liquid storage tank 4 is also provided with at least one faucet. The faucet is connected to the interior of the liquid storage tank 4, so that the user can control the faucet to dispense the environmentally friendly enzyme mixed fermentation liquid in the liquid storage tank 4 into other containers.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
