DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0026] With reference to Figures 1-6 , the utility model provides an embodiment:
[0027] The device for in-situ treatment of pig manure by microalgae and earthworms comprises a treatment box 1, a partition 2 fixedly arranged at the middle position of the inner end of the treatment box 1, a fixed pipe 3 fixedly arranged at one side of the inner end of the treatment box 1, a plurality of leakage holes 4 fixedly arranged at one side of the fixed pipe 3, a first motor 5 fixedly arranged at the side of the outer end of the treatment box 1 away from the partition 2, a transmission roller 6 fixedly arranged at the output end of the first motor 5, a feeding pipe 7 fixedly arranged at the outer end of the treatment box 1 relative to the first motor 5, a guide plate 9 fixedly arranged at the inner end of the treatment box 1 close to the first motor 5, a manure residue collecting box 12 movably arranged at one side of the inner bottom end of the treatment box 1, a second motor 13 fixedly arranged at one side of the manure residue collecting box 12, a stirring paddle 14 fixedly arranged at the output end of the second motor 13, a microalgae culture pond 10 movably arranged at one side of the inner bottom end of the treatment box 1 relative to the manure residue collecting box 12, a microalgae feeding port 11 fixedly arranged at the upper end of one side of the microalgae culture pond 10, a sawdust feeding port 8 fixedly arranged at one side of the upper end of the treatment box 1, the sawdust feeding port 8 being arranged at the side away from the fixed pipe 3 and above the manure residue collecting box 12, the fixed pipe 3 being fixedly connected with the partition 2, the plurality of leakage holes 4 being arranged above the microalgae culture pond 10, the transmission roller 6 being rotatably arranged at the inner end of the fixed pipe 3, the outlet of the feeding pipe 7 being arranged at the inner end of the fixed pipe 3, the guide plate 9 being rotatably arranged at the output end of the first motor 5, the stirring paddle 14 being rotatably arranged above the manure residue collecting box 12, and the microalgae culture pond 10 and the manure residue collecting box 12 being arranged at the two sides of the partition 2 respectively.
[0028] Specifically, the raw manure generated by the pig farm is added at the feeding pipe 7 of the treatment box 1, and since the raw manure is divided into dry materials and wet materials, after the raw manure enters the fixed pipe 3, the wet materials will seep into the microalgae culture pond 10 through the leakage holes 4 due to gravity, at this time, after the first motor 5 is started, the transmission roller 6 will start to rotate, thereby driving the two kinds of materials to move towards the manure residue collecting box 12, at this time, the wet materials will continue to leak into the microalgae culture pond 10 through the leakage holes 4, and the dry materials will finally fall into the manure residue collecting box 12 from the other side of the fixed pipe 3;
[0029] The wet materials falling into the microalgae culture pond 10 need to add chlorella and tetradesmus sp. through the microalgae feeding port 11, and such microalgae can absorb ammonia nitrogen, nitrate, phosphate and the like in the liquid as nutrients required for growth through photosynthesis, at the same time, photosynthesis can absorb carbon dioxide and release oxygen, thereby greatly improving the quality of the water body;
[0030] After the dry material falls into the dung collection box 12, broken wood chips need to be added from the wood chip feeding port 8, and the wood chips will enter the dung collection box 12 along the guide plate 9, which can protect the output end of the first motor 5 from being damaged. After the wood chips and the dry material enter the dung collection box 12, the second motor 13 is started, and the stirring paddle 14 fully mixes the wood chips and the dry material. After the wood chips and the dry material are mixed, earthworms are added from the wood chip feeding port 8. The earthworms eat solid dung and decompose organic matter into a more stable and more plant-absorbable form. At the same time, the activity of the earthworms can also loosen the material and increase the oxygen, thereby inhibiting anaerobic spoilage and the generation of odor. However, it should be noted that after the earthworms are added, the second motor 13 should not be started again, so as to prevent the stirring paddle 14 from damaging the earthworms.
[0031] Since the wet material may still contain part of the dung after entering the microalgae culture tank 10, after the microalgae culture is completed, the dung will be concentrated at the bottom of the microalgae culture tank 10. At this time, after the water in the microalgae culture tank 10 is completely discharged, the dung can also be added into the dung collection box 12 from the wood chip feeding port 8, thereby reducing material waste.
[0032] Working principle: The feed pipe 7 of the treatment box 1 is used to add raw dung produced by a pig farm. Since the raw dung is divided into dry material and wet material, after the raw dung enters the fixed pipe 3, the wet material will seep into the microalgae culture tank 10 from the leakage hole 4 due to gravity. At this time, after the first motor 5 is started, the transmission roller 6 will start to rotate, thereby driving the two materials to move in the direction of the dung collection box 12. At this time, the wet material will continue to leak into the microalgae culture tank 10 from the leakage hole 4, and the dry material will finally fall into the dung collection box 12 from the other side of the fixed pipe 3. The wet material falling into the microalgae culture tank 10 needs to add small ball algae and grid algae from the microalgae feeding port 11. Such microalgae can absorb carbon dioxide and release oxygen through photosynthesis, thereby greatly improving the quality of the water body. After the dry material falls into the dung collection box 12, broken wood chips are added from the wood chip feeding port 8, and the wood chips will enter the dung collection box 12 along the guide plate 9. After the wood chips and the dry material enter the dung collection box 12, the secondmotor 13 is started, and the stirring paddle 14 fully mixes the wood chips and the drymaterial. After the wood chips and the dry material are mixed, earthworms are added from thewood chip feeding port 8. The earthworms eat solid dung and decompose organic matter intoa more stable and more plant-absorbable form.
[0033] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
