Description

Technical Field

[0001] The present application relates to the technical field of storage tools, and in particular to a multi-layer composite steel barrel. Background Art

[0002] Steel drums are mostly used to store liquid materials. Sometimes the materials are highly corrosive, and the metal material of the cylinder cannot come into direct contact with the materials. It is necessary to coat the surface of the steel drum that contacts the materials with a corrosion-resistant layer. However, due to the thermal expansion and contraction effect of the metal, the corrosion-resistant layer may separate from the metal surface after a long period of use. If the inspection is not careful, the entire steel drum may be damaged and there is a risk of leakage. Summary of the invention

[0003] The purpose of the present application is to provide a multi-layer composite steel drum which is more durable and more convenient to use.

[0004] To achieve the above objectives, the present application provides a multi-layer composite steel barrel: comprising a plastic barrel body, the plastic barrel body is outer-coated with a ceramic barrel body, the ceramic barrel body is outer-coated with an alloy barrel body, the alloy barrel body comprises an outer barrel wall, the bottom of the outer barrel wall has a lower base plate, the outer barrel wall is provided with a pair of handles on the outer side, the two handles are close to the upper end of the outer barrel wall and are located on opposite sides, so as to facilitate the smooth transfer of the entire steel barrel.

[0005] Preferably, the handle is provided with a hanging hole and a hook groove, wherein the hanging hole is horizontal and passes through opposite sides of the handle, and the hook groove is longitudinal and extends upward from the bottom surface of the handle, so as to realize two different hanging states.

[0006] As a preference, the upper end of the outer barrel wall has an outer flange, and the outer side surfaces of the outer flange and the lower bottom plate both protrude from the outer side surface of the outer barrel wall. This can reduce the probability of the outer barrel wall being hit, because the raised outer flange 205 and the lower bottom plate 206 are more likely to be hit first during transportation.

[0007] Preferably, the outer surface of the outer barrel wall has reinforcing ribs, the upper ends of the reinforcing ribs extend to the lower surface of the outer flange, and the lower ends of the reinforcing ribs extend to the upper surface of the lower base plate, which can effectively improve the structural strength of the alloy barrel body.

[0008] As a preferred embodiment, the outer side surface of the outer barrel wall is also fixedly connected with a plurality of friction strips, and the plurality of friction strips are made of rubber or silicone material and are all arranged horizontally to increase the contact friction in the vertical direction.

[0009] Preferably, the plastic barrel body comprises an inner barrel wall, the lower end of the inner barrel wall has an inner bottom plate, and only the upper end is open for the entry and exit of materials.

[0010] Preferably, a sink groove is formed between the upper end surface of the outer barrel wall and the inner wall of the outer flange, and the upper end of the inner barrel wall has an inner edge suitable for fitting with the sink groove, so that the plastic body can be directly contacted and connected with the alloy barrel body.

[0011] Preferably, the ceramic barrel body includes an integrated middle bottom plate and a barrier barrel wall, wherein the middle bottom plate is located between the inner bottom plate and the lower bottom plate, and the barrier barrel wall is located between the inner barrel wall and the outer barrel wall, which can effectively weaken the effect of the corrosion-resistant layer falling off caused by thermal expansion and contraction.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] (1) By placing the ceramic layer between the plastic layer and the alloy layer, the probability of separation between the plastic layer and the alloy layer is reduced by utilizing the lower thermal expansion and contraction effect of the ceramic material, thereby improving the durability of the entire composite steel drum, making the steel drum safer and more convenient to use;

[0014] (2) When the steel drum needs to be scrapped after use, it is only necessary to break the ceramic layer from the inside, and then use the greater adsorption force of the ceramic and plastic layers to completely separate them from the metal part of the steel drum, thereby improving the cleanliness of the material, which is conducive to classified recycling and thus reducing the cost and difficulty of recycling.

[0023] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0026] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0027] like Figure 1-7 The multi-layer composite steel drum shown includes a steel alloy barrel body 2. The specific structure of the alloy barrel body 2 includes an outer barrel wall 201 with only an upper end open. The bottom of the outer barrel wall 201 has a lower bottom plate 206. The lower bottom plate 206 is used to seal the lower open end of the outer barrel wall 201. The upper end of the outer barrel wall 201 has an outer flange 205. The diameter of the outer flange 205 is larger than the diameter of the outer barrel wall 201. Therefore, a sink 207 structure is formed between the upper end surface of the outer barrel wall 201 and the inner wall of the outer flange 205.

[0028] The outer side surfaces of the outer flange 205 and the lower bottom plate 206 both protrude from the outer side surface of the outer barrel wall 201, so that the lower bottom plate 206 has a larger bottom area and can disperse the pressure, and the outer flange 205 allows the alloy barrel body 2 to have a grippable portion. The outer surface of the outer barrel wall 201 has reinforcing ribs 203, and the reinforcing ribs 203 are usually arranged in the longitudinal direction, which can effectively improve the compressive resistance of the alloy barrel body 2. The upper end of the reinforcing rib 203 extends to the lower surface of the outer flange 205, and the lower end of the reinforcing rib 203 extends to the upper surface of the lower bottom plate 206, which is almost the same as the longitudinal height of the outer barrel wall 201. Therefore, the entire alloy barrel body 2 has good structural strength. The outer side surface of the outer barrel wall 201 is also fixedly connected to a plurality of friction strips 204. These friction strips 204 are made of materials with a high friction coefficient such as rubber or silicone, and are all arranged horizontally to provide a larger contact friction when holding the steel barrel.

[0029] A pair of handles 220 are provided on the outer side of the outer barrel wall 201. The outer side of the handles 220 is flush with the outer side of the outer flange 205. The two handles 220 are close to the upper end of the outer barrel wall 201 and are located on opposite sides. It is easier to keep the entire steel barrel stable by applying force on the symmetrical sides. A hanging hole 221 and a hook groove 222 are provided on the handle 220. The hanging hole 221 is horizontal and passes through the opposite side of the handle 220 to allow the hook to pass through. The hook groove 222 is longitudinal and extends upward from the bottom surface of the handle 220. The bottom surface of the handle 220 is an inclined surface, so the hook groove 222 is deeper as it goes up, and is used to engage with the end of the hook. Although it is not as stable as the hanging hole 221, the advantage is that it can be quickly disassembled and assembled, which is beneficial to improving the efficiency of loading and unloading steel barrels.

[0030] A ceramic barrel body 3 is arranged inside the alloy barrel body 2. Since the thermal conductivity of ceramic materials is relatively poor, they have a certain heat insulation effect. The ceramic barrel body 3 is fixedly connected to the alloy barrel body 2 by the curing glue on the outer surface. A plastic barrel body 1 is arranged inside the ceramic barrel body 3. The plastic is made of polymerized high molecular material and has good corrosion resistance. At the same time, the harder ceramic barrel body 3 can maintain the shape of the plastic barrel body 1. The plastic barrel body 1 is fixedly connected to the ceramic barrel body 3 by the curing glue on the outer surface. The specific structure of the plastic barrel body 1 includes an inner barrel wall 102. The lower end of the inner barrel wall 102 has an inner bottom plate 101, and the upper end of the inner barrel wall 102 has an inner card edge 103, which fits exactly with the sink 207. The specific structure of the ceramic barrel body 3 includes an integrated middle bottom plate 301 and a barrier barrel wall 302. The middle bottom plate 301 is located exactly between the inner bottom plate 101 and the lower bottom plate 206, and the barrier barrel wall 302 is located exactly between the inner barrel wall 102 and the outer barrel wall 201.

[0031] Manufacturing method: the first step is to make an alloy barrel body 2, forming the metal part of the alloy body by casting, and then forming the hanging hole 221 and then the hook groove 222 on the handle 220 by cutting. The lower bottom plate 206 will open a small hole that runs through the upper and lower end surfaces for exhaust during assembly, and finally use curing glue to fix the friction strip 204 to the outer surface of the outer barrel wall 201; the second step is to make a ceramic barrel body 3, forming the ceramic barrel body 3 by mold molding, and then hardening it by baking. A small hole will also be reserved at the bottom of the ceramic barrel body 3 for exhaust; the third step is to make a plastic barrel body 1, and then form it by injection molding. The molding can be done in one step; finally, assemble, evenly apply curing glue on the outer surface of the plastic barrel body 1, and then press the plastic barrel body 1 into the ceramic barrel body 3 until the inner bottom plate 101 fits with the middle bottom plate 301, and the inner card edge 103 is close to the upper end surface of the interlayer barrel wall 302, and then evenly apply curing glue on the outer surface of the ceramic barrel body 3, and press the ceramic barrel body 3 and the plastic barrel body 1 together into the alloy barrel body 2 until the inner card edge 103 is completely sunk into the sink 207 at the upper end of the alloy barrel body 2, wait for the curing glue to solidify, and spray a layer of anti-rust paint on the exposed surface of the alloy barrel body 2 to complete the production of the entire multi-layer composite steel barrel.
