[0001] The utility model relates to the technical field of heat preservation barrels, in particular to a heat preservation barrel with an inner heat preservation layer. Background Art

[0002] Rural domestic sewage mainly refers to the sewage generated by rural residents' living activities, mainly including drainage from toilet flushing, washing, bathing, and kitchens. Rural domestic sewage treatment is to remove and degrade harmful substances and environmental pollutants in domestic sewage to make it harmless. Using a solid-liquid separation device to separate solids and liquids from sewage can reduce the water content of the discharged material. The separated sludge can be reused as raw material for organic fertilizers, while reducing the content of suspended solids in the effluent and reducing environmental pollution.

[0003] When performing the above water treatment, a barrel is needed as a container to store and hold the water treatment device. When using the existing barrel for water treatment, in the case of low temperature, the sewage in the barrel will freeze, resulting in blocked pipelines and unable to perform subsequent sewage treatment. Even in the case of extremely low temperature, the excessive expansion of the frozen sewage in the barrel will cause the barrel to burst. Content of the Utility Model

[0004] Therefore, the technical problem to be solved by the present utility model is to overcome the problem that when using a barrel for water treatment in the prior art, in the case of low temperature, the sewage in the barrel will freeze, resulting in inability to perform subsequent sewage treatment. Even in the case of extremely low temperature, the excessive expansion of the frozen sewage in the barrel will cause the barrel to burst. Thus, a heat preservation barrel with an inner heat preservation layer is provided.

[0005] To solve the above technical problem, the present utility model provides a heat preservation barrel with an inner heat preservation layer, including:

[0006] A barrel body having a receiving cavity and an opening communicating therewith;

[0007] Rib bodies, including: first longitudinal ribs and transverse ribs respectively arranged on the barrel body along the height direction and the circumferential direction, and first and second groove bodies formed in the receiving cavity by the first longitudinal ribs and the transverse ribs and the barrel body;

[0008] A heat preservation layer covering the wall of the receiving cavity and the first and second groove bodies, and the heat preservation layer is a foaming layer.

[0009] In an embodiment of the present utility model, the heat preservation layer is any one of a polyethylene foaming layer, a polyurethane foaming layer, and a polypropylene foaming layer.

[0010] In an embodiment of the present utility model, the thickness of the heat preservation layer is 0.5 cm - 1.5 cm.

[0011] In an embodiment of the present utility model, the thickness of the barrel body is 1 cm - 3 cm.

[0012] In an embodiment of the present utility model, the wall body of the accommodating cavity is covered with an attachment layer, and the attachment layer is a pe attachment agent layer sprayed on the accommodating cavity or a rough layer provided on the wall of the accommodating cavity.

[0013] In an embodiment of the present utility model, a support layer and a corrosion-resistant layer are further sequentially covered on the surface of the heat-insulating layer. The material of the support layer is the same as that of the barrel body, and the corrosion-resistant layer is a polytetrafluoroethylene layer.

[0014] In an embodiment of the present utility model, the barrel body is provided with two groups of openings, and the two groups of openings are arranged along the length direction of the barrel body.

[0015] In an embodiment of the present utility model, the wall thickness of the barrel body is uniform. The longitudinal ribs extend into the accommodating cavity and form a first groove on the outer wall of the barrel body. The transverse ribs are arranged at both ends in the length direction of the barrel body, and the transverse ribs extend away from the barrel body and form a second groove on the inner wall of the barrel body.

[0016] In an embodiment of the present utility model, a second longitudinal rib is arranged between the two groups of openings. The second longitudinal rib is annularly arranged on the outer side wall of the barrel body, and the second longitudinal rib forms a third groove in the accommodating cavity.

[0017] In an embodiment of the present utility model, the barrel body is further provided with a third longitudinal rib. The third longitudinal rib is arranged on the inner side wall of the barrel body. The third longitudinal rib forms a fourth groove on the outer side wall of the barrel body. The bottom surface of the fourth groove is provided with a fourth longitudinal rib. The width of the fourth groove is greater than that of the fourth longitudinal rib. The fourth longitudinal rib is arranged on the outer side wall of the barrel body, and the fourth longitudinal rib forms a fifth groove in the accommodating cavity.

[0018] The above technical solution of the present utility model has the following advantages compared with the prior art:

[0019] A heat-insulating bucket with an inner heat-insulating layer according to the present utility model, the accommodating cavity of the bucket body is used to accommodate grey water, black water and corresponding treatment devices. By covering a foamed heat-insulating layer on the wall of the accommodating cavity, and by providing the first longitudinal ribs, the first grooves, the transverse ribs and the second grooves, not only can the cross-sectional area of the bucket body be increased to enhance the structural strength of the bucket body, but also the heat-insulating layer can better adhere to the inner accommodating cavity of the bucket body. The heat-insulating layer is embedded in the first grooves and the second grooves to prevent the heat-insulating layer from falling off. The heat-insulating layer has a large number of closed pores, thereby reducing heat conduction, effectively preventing air convection and heat radiation. When the sewage in the bucket freezes and expands at extremely low temperatures, the first longitudinal ribs, the first grooves, the transverse ribs and the second grooves can correspondingly stretch and deform, increasing the volume inside the bucket, avoiding the bursting of the bucket body, and cooperating with the heat-insulating layer to achieve a good heat-insulating effect, preventing the grey water and black water in the bucket from freezing at low temperatures, and ensuring the smooth and normal operation of the water purification device and pipelines.

[0026] The following further illustrates the present utility model in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model. Embodiment

[0027] Referring to Figures 1-4 as shown, a heat-insulating bucket with an inner heat-insulating layer 10 of the present utility model includes:

[0028] A barrel body 1, which has a receiving cavity and an opening 2 communicating therewith;

[0029] A rib body, which includes: a first longitudinal rib 7 and a transverse rib 4 respectively arranged on the barrel body 1 along the height direction and the circumferential direction, and a first groove body 8 and a second groove body 9 respectively formed in the receiving cavity by the first longitudinal rib 7 and the transverse rib 4 and the barrel body 1;

[0030] A heat insulation layer 10, which covers the wall of the receiving cavity, the first groove body 8 and the second groove body 9, and the heat insulation layer 10 is a foaming layer.

[0031] A heat-insulated barrel with an internal heat insulation layer 10 according to the present utility model. The receiving cavity of the barrel body 1 is used to accommodate gray water, black water and corresponding treatment devices. By covering the wall of the receiving cavity with a foamed heat insulation layer 10, and by arranging the first longitudinal rib 7 and the first groove body 8, and the transverse rib 4 and the second groove body 9, not only can the cross-sectional area of the barrel body 1 be increased to increase the structural strength of the barrel body 1, but also the heat insulation layer 10 can be better attached to the receiving cavity of the barrel body 1. The heat insulation layer 10 is embedded in the first groove body 8 and the second groove body 9 to prevent the heat insulation layer 10 from falling off. The heat insulation layer 10 has a large number of closed pores, thereby reducing heat conduction, and can effectively prevent air convection and heat radiation, thus achieving a good heat insulation effect, preventing the black water and gray water in the barrel from freezing due to low temperature, and ensuring the smoothness of the water purification device and the pipeline.

[0032] The number of the first longitudinal ribs 7 is multiple, and the heat insulation layer 10 is also correspondingly arranged in the grooves between the multiple first longitudinal ribs 7, so as to prevent the heat insulation layer 10 from falling off.

[0033] The shape of the first longitudinal rib 7 is a long oval shape, and there is an arc transition between the first longitudinal rib 7 and the wall of the barrel body 1.

[0034] The heat insulation layer 10 is any one of a polyethylene foaming layer, a polyurethane foaming layer, and a polypropylene foaming layer. The polyethylene foaming layer, the polyurethane foaming layer, and the polypropylene foaming layer can all achieve the purpose of heat insulation. The polyurethane rigid foam is a closed-cell organic foam, and its closed-cell rate reaches more than 90%. The diameter of the foaming pores is about in the um level, and the pores are similar to a honeycomb structure. The pores are composed of a mixed gas of a foaming agent, air and carbon dioxide. In this embodiment, the foamed heat insulation layer 10 is selected as a pe foaming layer. PE-LD with a melt flow rate (190 °C, 10 min) of 0.5-6 g is used as the main raw material for manufacturing the PE foaming material, and the method of mixing PE-HD with PE-MD or PE-LD is adopted to delay crystallization and change the fluidity of the material, so that the foaming material can not only maintain a certain softness but also improve the strength.

[0035] The thickness of the heat insulation layer 10 is 0.5 cm - 1.5 cm, which can meet the heat insulation requirements of most regions. In this embodiment, the thickness of the heat insulation layer 10 is 1 cm. A thickness of 1 cm can effectively prevent heat loss, and at the same time, it will not make the internal space of the barrel 1 too narrow. Moreover, it is also reasonable in terms of manufacturing cost. Similarly, the thickness of the barrel 1 is 1 cm - 3 cm, which can ensure the structural strength of the barrel 1 and balance the production cost. When the barrel 1 bears the pressure from the internal items or external collisions, the thickness in the range of 1 cm - 3 cm can disperse and bear these forces. In this embodiment, the thickness of the barrel 1 is selected as 2 cm, and the distribution and structure of its material can evenly bear the stress, avoiding the barrel 1 from cracking due to local stress concentration.

[0036] The wall body of the accommodation cavity is covered with an attachment layer, and the attachment layer is a pe attachment agent layer sprayed on the accommodation cavity, that is, spray a layer of Pe water on the Pe substrate, namely the Pe attachment agent. It increases the surface energy of the Pe material, facilitating the attachment of various groups in the paint, such as the Pe adhesion promoter 153-2, or a rough layer provided on the wall of the accommodation cavity, forming a rough surface layer on the inner wall of the accommodation cavity through grinding treatment, sandblasting treatment or flame treatment to improve the adhesion of the foaming layer.

[0037] The surface of the heat insulation layer 10 is also sequentially covered with a support layer and a corrosion-resistant layer. The material of the support layer is the same as that of the barrel 1, and the corrosion-resistant layer is a polytetrafluoroethylene layer. In this embodiment, both the support layer and the barrel 1 are made of pe. The PE material has good flexibility, impact resistance and certain strength.

[0038] As Figures 1-4 shown, the barrel 1 is provided with two groups of openings 2, making the barrel body have length and width, forming a similar horizontally placed cylindrical barrel. The two groups of openings 2 are arranged along the length direction of the barrel 1 and are opened above the barrel 1.

[0039] The wall thickness of the barrel 1 is uniform. The barrel body is made by rotational molding process or blow molding process. The rotational molding process is to pour the plastic raw material powder into the mold, then heat the mold and make it rotate along two perpendicular axes, so that the plastic raw material is evenly coated and fused on the inner wall of the mold, and finally a barrel body 1 with uniform thickness is formed. The blow molding process is to place the plastic parison in the mold and blow it up by compressed air to closely adhere to the inner wall of the mold, and a product with uniform thickness is obtained after cooling. Ensure that the thickness of each part of the barrel 1 is equal, and the ribs on one side of the barrel 1 will form grooves on the corresponding side on the other side. The longitudinal ribs extend into the accommodation cavity and form a first groove 8 on the outer wall of the barrel 1. The transverse ribs are arranged at both ends of the barrel 1 in the length direction, and the transverse ribs 4 extend away from the barrel 1 and form a second groove 9 on the inner wall of the barrel 1.

[0040] As Figure 2As shown, a second longitudinal rib 3 is provided between the two sets of openings 2. The second longitudinal rib 3 is disposed around the outer sidewall of the barrel body 1. The second longitudinal rib 3 forms a third groove 13 in the accommodating cavity. When the barrel body 1 is subjected to an external force during use, the second longitudinal rib 3 can enhance the structural strength of the portion of the barrel body 1 between the openings 2, effectively resisting deformation and damage caused by the external force. At the same time, the formed third groove 13 provides an attachment structure for the heat insulation layer 10.

[0041] As Figure 2 shown, the barrel body 1 is further provided with a third longitudinal rib 5. The third longitudinal rib 5 is disposed on the inner sidewall of the barrel body 1. The third longitudinal rib 5 forms a fourth groove 6 on the outer sidewall of the barrel body 1. The bottom surface of the fourth groove 6 is provided with a fourth longitudinal rib 11. The width of the fourth groove 6 is greater than that of the fourth longitudinal rib 11, and the size of the fourth groove 6 is greater than that of the fourth longitudinal rib 11. The fourth longitudinal rib 11 is disposed on the outer sidewall of the barrel body 1. The fourth longitudinal rib 11 forms a fifth groove 12 in the accommodating cavity. The third longitudinal rib 5 can enhance the structural strength of the inner sidewall of the barrel body 1 and improve the resistance of the barrel body 1 to internal pressure and external impact.

[0042] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
