[0002] In the production of composite pipes of some specifications, high-density polyethylene and ingredients need to be mixed in proportion, so that the wrapping material of the outer wall of the composite pipe can be formed after hot-melt stirring in the later stage, so that the product can meet the use requirements. In the prior art, in order to facilitate transportation, both raw materials are granular substances. Before use, the operator needs to pour the required raw materials into the raw material bucket according to a certain proportion for stirring, and then pump the original particles into the hot-melt stirring equipment through the negative pressure pipe. However, the mixing degree of the raw materials stirred manually is low. In the process of pumping the raw materials through the negative pressure pipe, it is impossible to control the ratio of the two raw materials near the pipe mouth of the negative pressure pipe to be the same or close to the required ratio, which reduces the production quality of the product. In addition, due to the low mixing degree, the mixing time after the subsequent hot melt is also increased, and the manpower and time of the operator are wasted, which reduces the production efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] The rubber pellet mixing feeding pipe for composite pipe production described in the utility model comprises a three-way connector 1 and a static mixing pipe 3. The three-way connector 1 comprises a first connector 11 and a second connector 12 arranged coaxially, and the axis of the third connector 13 and the axis of the second connector 12 are at an acute angle. The first connector 11 of the three-way connector 1 is connected to the negative pressure pipeline through the static mixing pipe 3, and the two raw materials are pumped into the hot melt mixing equipment through the negative pressure pipeline. The second connector 12 and the third connector 13 are respectively connected to a pipeline. During the working process, the two raw materials can be poured into two collecting buckets respectively, and the two pipes are respectively inserted into the raw material pile to extract the raw materials in the two collecting buckets through negative pressure. The inner diameter of the second connector 12 and the inner diameter of the third connector 13 are set according to the required ratio of the two raw materials. For example, in this embodiment, if the required ratio of polyethylene to the ingredients is 2:1, the cross-sectional area ratio of the second connector 12 and the third connector 13 should also be 2:1, so that the ratio of the extracted raw materials is consistent with the required ratio.

[0029] A separator 2 is provided in the second connector 12, and the separator 2 divides the second connector 12 into two feed channels, and the third connector 13 is connected to one of the feed channels. When the raw material enters the second connector 12, the raw material is divided into two parts and enters the two feed channels respectively. The ingredients entering from the third connector 13 are first mixed with the material in one of the feed channels and move along the negative pressure direction, and then mixed with the material in the other feed channel. Specifically, an angle is provided between the length direction of the separator 2 and the axis of the second connector 12, and the axis of the third connector 13 can pass through the separator 2, and an acute angle is provided between the axis of the third connector 13 and the length direction of the separator 2; for the feed channel 14 connected to the third connector 13, the feed channel Under the guidance of the separator 2, the material in 14 moves toward the third connector 13. At the same time, when the raw material in the third connector 13 enters the feeding channel 14, it can impact and collide with the raw material in the feeding channel 14, thereby disrupting the movement direction of the raw material in the feeding channel 14 and the third connector 13, so that the raw material in the third connector 13 and the material in the feeding channel 14 are initially mixed. Furthermore, the reason why the raw materials in the second connector 12 and the third connector 13 are not directly mixed by impact is that the amount of raw materials in contact and mixing in the second connector 12 and the third connector 13 is similar, so that the flow rate of the raw material in the third connector 13 can have a greater impact effect on the flow rate of the raw material in the feeding channel 14, so that the two raw materials are mixed more evenly. In order to further enhance the impact effect, the cross-section of the separator 2 is arc-shaped, and the top of the arc faces the third connector 13, so that the raw materials entering the material channel connected to the third connector 13 are divided into two streams, and the raw materials in the feeding channel 14 facing the top of the arc are less, and a part of the raw materials in the third connector 13 directly impacts the raw materials in the material channel, causing the raw materials to eject and jump, and the other part impacts the top of the arc of the separator 2, thereby changing the ejection angle, thereby further disrupting the flow of objects in the feeding channel 14 and improving the mixing effect.

[0030] In order to install the separator 2, two slide grooves 15 are axially provided on the inner wall of the second connecting head 12, and slide bars 21 extend outward on both sides of the separator 2, and the slide bars 21 are placed in the slide grooves 15. The inner diameter of the first connecting head 11 gradually decreases from the inside to the outside, so that the slide groove 15 can be against the inner wall of the first connecting head 11, and the separator 2 is prevented from falling by the friction between the slide bar 21 and the slide groove 15, the negative pressure effect of the negative pressure tube and the impact of the material. More specifically, in order to make the angle between the length direction of the separator 2 and the axis of the third connecting head 13 smaller than the angle between the axis of the third connecting head 13 and the axis of the second connecting head 12, the cross-sectional curvature of the separator 2 gradually increases from the outer end to the inner end of the second connecting head 12.

[0031] The outer ends of the second connector 12 and the third connector 13 extend outwardly with flanges 16, and the flanges 16 are in a bell-mouth shape, and the inner diameter of the end close to the second connector 12 or the third connector 13 is smaller than the inner diameter of the end away from the second connector 12 or the third connector 13, so as to facilitate the fixing of the pipes plugged into the second connector 12 and the third connector 13. Specifically, the pipe is sleeved on the second connector 12 or the third connector 13, and the flange 16 is tightly against the inner wall of the pipe, and the bell-mouth makes it easier for the raw materials in the pipe to enter the three-way connector 1. The pipe in this embodiment is a hose, and in order to make the connection between the pipe and the three-way connector 1 more secure, the pipe mouth of the pipe can be locked and fixed by parts such as a throat clamp and a clamp.

[0032] The static mixer 3 is provided with a plurality of first baffles 31 and second baffles 32, and the projection of the first baffles 31 can block the cross section of one of the feed channels in the second connector 12, and the projection of the second baffles 32 can block the cross section of another feed channel. The first baffles 31 and the second baffles 32 are arranged alternately in the static mixer 3, and an acute angle is formed between each baffle and the axis of the static mixer 3. After the raw materials preliminarily mixed in the feed channel 14 and the third connector 13 and the raw materials in another feed channel 14 enter the static mixer 3, turbulence is formed by the staggered baffles, and at this time, the raw materials in the feed channel 14 close to the third connector 13 and the raw materials in the third connector 13 complete the confluence of the raw materials, and the difference in the amount of the raw materials in it and the raw materials in the other feed channel 14 is reduced or even more, so that the raw material particles in the two feed channels 14 are further mixed in the static mixer 3.

[0033] In this embodiment, the static mixing tube 3 and the first connector 11 are connected by threads, and the other end of the static mixing tube 3 is provided with barbs, and the negative pressure pipe can be inserted into the other end of the static mixing tube 3 and fixed by parts such as clamps or clamps. The baffle can be directly fixed (such as clamping, bonding, etc.) in the static mixing tube 3; it can also be produced by fixing multiple sheets on a core shaft first, and then inserting the core shaft and the sheet body as a whole into the static mixing tube 3 for fixing. The specific connection method is the existing technology and will not be repeated here.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
