Description

Technical Field

[0001] This invention belongs to the field of instant liquid supply. Background Technology

[0002] Some liquid mixtures require timely mixing, such as coatings, paints, and other industrial liquids containing epoxy resin. In the process of mixing raw materials, raw material n and raw material m will undergo a curing reaction in a short time after mixing, so it needs to be mixed and used immediately. In high-volume scenarios such as painting plants, the raw material conveying of the instant mixing device also needs to be conveyed according to a certain transmission ratio. It is also necessary to change the total transmission rate in real time according to the on-site painting rate without changing the transmission ratio. At the same time, it is also necessary to have the ability to flexibly change the ratio of transmission rates of raw material n and raw material m as needed. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the prior art, the present invention provides an instant mixing coating raw material supply system and a supply rate ratio adjustment method, which can flexibly change the ratio of the transmission rates of raw material n and raw material m as needed.

[0004] Technical solution: To achieve the above objective, the raw material supply system for the mixed coating of the present invention is characterized in that: it includes an n-plunger pump body and an m-plunger pump body, the n-plunger pump body and the m-plunger pump body are arranged coaxially and symmetrically, and the n-plunger and m-plunger are respectively arranged in the n-plunger liquid tank and the m-plunger liquid tank in the n-plunger pump body and the m-plunger pump body.

[0005] The n-plunger and m-plunger are coaxially and integrally connected on their respective sides.

[0006] It also includes a guide rail parallel to the n-plunger push rod / m-plunger push rod, on which a slider capable of active displacement is provided. The slider is fixedly connected to a synchronous beam through a connecting arm. The two ends of the synchronous beam are respectively fixedly connected to the n-plunger push rod and the m-plunger push rod, so that the n-plunger push rod and the m-plunger push rod are synchronized under the action of the synchronous beam.

[0007] Furthermore, an n-transition chamber is coaxially arranged at the axis of the n-plunger, and an n-hydraulic cylinder is penetrating along the axis of the n-plunger push rod. One end of the n-transition chamber is connected to the n-hydraulic cylinder, and an n-baffle is fixedly arranged at the end of the n-transition chamber away from the n-plunger push rod. The n-baffle is flush with the end face of the n-plunger. A disc-shaped n-elastic wall is coaxially arranged on the side of the n-baffle away from the n-transition chamber. Several n-permeable holes are evenly distributed on the n-baffle. When the pressure in the n-transition chamber increases, the liquid in the n-transition chamber is squeezed through the several n-permeable holes and squeezed between the n-elastic wall and the n-baffle, thereby causing the n-elastic wall to bulge outward in a spherical shape, forming an n-bulging cavity between the n-elastic wall and the n-baffle.

[0008] Furthermore, an n-hydraulic adjusting cylinder is coaxially arranged inside the n-hydraulic column cavity, and the outer wall of the n-hydraulic adjusting cylinder is slidably sealed to the inner wall of the n-hydraulic column cavity through a first O-ring seal.

[0009] Furthermore, the n hydraulic regulating cylinder contains an n pressure compensation column chamber. An inner wall at the end of the n hydraulic regulating cylinder furthest from the n transition chamber is provided with an n limiting inner edge. A n follower piston is movably mounted within the n pressure compensation column chamber, and a n pressure spring is also provided within the n pressure compensation column chamber. The n pressure spring exerts a thrust along the axial direction on the n follower piston, causing the n follower piston to press against the n limiting inner edge. The end of the n pressure compensation column chamber furthest from the n follower piston is connected to the n hydraulic column cavity through an n connecting hole. It also includes an n electric telescopic device. The n telescopic rod of the n electric telescopic device is parallel to the axis of the n hydraulic regulating cylinder, and the end of the n telescopic rod is fixedly connected to the n hydraulic regulating cylinder through an n arm.

[0010] Furthermore, an m transition chamber is coaxially arranged at the axis of the m plunger, and an m hydraulic cylinder cavity runs through the m plunger push rod along the axial direction. One end of the m transition chamber is connected to the m hydraulic cylinder cavity, and an m baffle is fixedly arranged at the end of the m transition chamber away from the m plunger push rod. The m baffle is flush with the end face of the m plunger. A disc-shaped m elastic wall is coaxially arranged on the side of the m baffle away from the m transition chamber. Several m liquid permeation holes are evenly distributed on the m baffle. When the pressure in the m transition chamber increases, the liquid in the m transition chamber is squeezed through the several m liquid permeation holes and squeezed between the m elastic wall and the m baffle, thereby causing the m elastic wall to bulge outward in a spherical shape, forming an m bulging cavity between the m elastic wall and the m baffle.

[0011] Furthermore, an m hydraulic adjusting cylinder is coaxially arranged inside the m hydraulic column cavity, and the outer wall of the m hydraulic adjusting cylinder is slidably sealed to the inner wall of the m hydraulic column cavity through a second O-ring seal.

[0012] Furthermore, the m hydraulic regulating cylinder contains an m pressure compensation column chamber. An m limiting inner edge is provided on the inner wall of the end of the m hydraulic regulating cylinder furthest from the m transition chamber. An m follower piston is movably mounted within the m pressure compensation column chamber, and an m pressure spring is also provided within the m pressure compensation column chamber. The m pressure spring exerts a thrust along the axial direction on the m follower piston, causing the m follower piston to press against the m limiting inner edge. The end of the m pressure compensation column chamber furthest from the m follower piston is connected to the m hydraulic column cavity through an m connecting hole. It also includes an m electric telescopic device. The m telescopic rod of the m electric telescopic device is parallel to the axis of the m hydraulic regulating cylinder, and the end of the m telescopic rod is fixedly connected to the m hydraulic regulating cylinder through an m arm.

[0013] Furthermore, the inlet and outlet ends of the n-plunger pump body are respectively equipped with a first check valve and a second check valve; the inlet and outlet ends of the m-plunger pump body are respectively equipped with a third check valve and a fourth check valve.

[0014] Furthermore, a method for adjusting the supply rate of the raw material supply system for mixed coatings:

[0015] If you want to increase the pump volume w1 of one pumping cycle in the n plunger pump body, control the n telescopic rod to actively move to the right, driving the n hydraulic regulating cylinder to move to the right a certain distance and then stop.

[0016] To increase the pump volume w2 of one pumping cycle within the m plunger pump body, control the m telescopic rod to actively move to the left, causing the m hydraulic regulating cylinder to shift to the left a certain distance before coming to rest.

[0017] Beneficial effects: The material conveying of this instant mixing and feeding system can change the total conveying rate in real time as needed, without changing the conveying rate ratio of raw material n and raw material m. At the same time, it can also flexibly change the ratio of the conveying rates of raw material n and raw material m as needed. Attached Figure Description

[0024] The invention will now be further described with reference to the accompanying drawings.

[0025] As attached Figures 1 to 6 The raw material supply system for the mixed coating shown is as follows: Figure 1It includes an n-raw material input pipe 1.1, an m-raw material input pipe 1.2, an n-plunger pump body 3.1, an m-plunger pump body 3.2, an n-raw material output pipe 2.1, and an m-raw material output pipe 2.1, respectively, for conveying n-raw material and m-raw material. The liquid outlet ends of the n-raw material output pipe 2.1 and the m-raw material output pipe 2.1 are connected to the mixing and stirring unit. The pump inlet and pump outlet ends of the n-plunger pump body 3.1 are connected to the n-raw material input pipe 1.1 and the n-raw material output pipe 2.1, respectively. The pump inlet and pump outlet ends of the m-plunger pump body 3.2 are connected to the m-raw material input pipe 1.2 and the m-raw material output pipe 2.1, respectively. The outlet ends of the n-raw material output pipe 2.1 and the m-raw material output pipe 2.1 are connected to the feed end of the mixing and stirring unit.

[0026] like Figure 2 The inlet and outlet ends of the n-plunger pump body 3.1 are respectively equipped with a first check valve 30a and a second check valve 30b; the inlet and outlet ends of the m-plunger pump body 3.2 are respectively equipped with a third check valve 30c and a fourth check valve 30d.

[0027] The n-plunger pump body 3.1 and the m-plunger pump body 3.2 are symmetrically arranged coaxially on the left and right sides. The n-pump liquid chamber 32.1 and the m-pump liquid chamber 32.2 inside the n-plunger pump body 3.1 and the m-pump liquid chamber 32.2 are respectively provided with n-plunger 23.1 and m-plunger 23.2. The n-plunger push rod 4.1 and the m-plunger push rod 4.2 are coaxially and integrally connected on the side of the n-plunger 23.1 and the m-plunger push rod 4.2 respectively. It also includes a guide rail 25 parallel to the n-plunger push rod 4.1 / m-plunger push rod 4.2. The guide rail 25 is provided with a slider 26 that can actively move. The slider 26 is fixedly connected to the synchronization beam 28 through the connecting arm 27. The two ends of the synchronization beam 28 are fixedly connected to the n-plunger push rod 4.1 and the m-plunger push rod 4.2 respectively, so that the n-plunger push rod 4.1 and the m-plunger push rod 4.2 are synchronized under the action of the synchronization beam 28.

[0028] Its general principle is, such as Figure 2 The slider 26 is controlled to periodically move left and right. Under the action of the synchronous beam 28, the n plunger 23.1 and m plunger 23.2 move left and right with the same frequency and amplitude in the n plunger pump body 3.1 and m plunger body 3.2, respectively. This causes the n plunger pump body 3.1 and m plunger body 3.2 to pump liquid at the same frequency, so that the n raw material output pipe 2.1 and m raw material output pipe 2.1 continuously export the n raw material and m raw material to the timely mixing and stirring unit, respectively.

[0029] like Figure 3 and 4A transition chamber 18.1 is coaxially disposed within the n-piston 23.1. A hydraulic cylinder 17.1 extends through the n-piston push rod 4.1 along its axial direction. One end of the transition chamber 18.1 is connected to the hydraulic cylinder 17.1. A baffle 19.1 is fixedly disposed at the end of the transition chamber 18.1 away from the n-piston push rod 4.1, and the baffle 19.1 is flush with the end face of the n-piston 23.1. A disc-shaped elastic wall 21.1 is coaxially disposed on the side of the baffle 19.1 away from the transition chamber 18.1. The elastic wall 21.1 can be made of elastic latex or rubber. The outer edge of 21.1 is tightly and sealed against the end face of the n plunger 23.1 by the n pressure ring 22.1, and the n pressure ring 22.1 is locked to the end face of the n plunger 23.1 by flange bolts; a number of n liquid permeation holes 20.1 are evenly distributed on the n baffle 19.1; when the pressure in the n transition chamber 18.1 increases, the liquid in the n transition chamber 18.1 is squeezed through the number of n liquid permeation holes 20.1 and squeezed between the n elastic wall 21.1 and the n baffle 19.1, so that the n elastic wall 21.1 bulges outward in a spherical shape, and an n bulging cavity 24.1 is formed between the n elastic wall 21.1 and the n baffle 19.1;

[0030] A hydraulic regulating cylinder 9.1 is coaxially arranged inside the hydraulic cylinder cavity 17.1 and extends along the axial direction. The outer wall of the hydraulic regulating cylinder 9.1 is slidably sealed to the inner wall of the hydraulic cylinder cavity 17.1 by a first O-ring seal 10.1.

[0031] The n hydraulic regulating cylinder 9.1 contains an n pressure compensation column chamber 14.1. An inner limit edge 13.1 is provided on the inner wall of the n hydraulic regulating cylinder 9.1 at the end furthest from the n transition chamber 18.1. A follower piston 11.1 is movably mounted inside the n pressure compensation column chamber 14.1. A pressure spring 15.1 is also provided inside the n pressure compensation column chamber 14.1, and the pressure spring 15.1 exerts a thrust along the axial direction on the follower piston 11.1, causing the follower piston 11.1 to press against the inner limit edge 13.1. The end of the n pressure compensation column chamber 14.1 furthest from the follower piston 11.1 is connected to the n hydraulic column cavity 17.1 through an n connecting hole 16.1. The system also includes an n electric telescopic device 5.1. The telescopic rod 6.1 of the n electric telescopic device 5.1 is parallel to the axis of the n hydraulic regulating cylinder 9.1, and the end of the telescopic rod 6.1 is fixedly connected to the n hydraulic regulating cylinder 9.1 through an n arm 8.1.

[0032] like Figure 5 and 6An m-transition chamber 18.2 is coaxially disposed within the m-plunger 23.2. An m-hydraulic cylinder 17.2 extends through the m-plunger push rod 4.2 along its axial direction. One end of the m-transition chamber 18.2 is connected to the m-hydraulic cylinder 17.2. An m-baffle 19.2 is fixedly disposed at the end of the m-transition chamber 18.2 away from the m-plunger push rod 4.2. The m-baffle 19.2 is flush with the end face of the m-plunger 23.2. A disc-shaped m-elastic wall 21.2 is coaxially disposed on the side of the m-baffle 19.2 away from the m-transition chamber 18.2. The outer edge of the m-elastic wall 21.2 is connected by an m-pressure ring. 22.2 A tight and sealed ring is pressed against the end face of the m plunger 23.2, and the m pressure ring 22.2 is locked to the end face of the m plunger 23.2 by flange bolts; several m liquid permeation holes 20.2 are evenly distributed on the m baffle 19.2; when the pressure in the m transition chamber 18.2 increases, the liquid in the m transition chamber 18.2 is squeezed through several m liquid permeation holes 20.2 and squeezed between the m elastic wall 21.2 and the m baffle 19.2, so that the m elastic wall 21.2 bulges outward in a spherical shape, and an m bulging cavity 24.2 is formed between the m elastic wall 21.2 and the m baffle 19.2;

[0033] A hydraulic regulating cylinder 9.2 is coaxially arranged inside the hydraulic cylinder cavity 17.2 and runs through the axial direction. The outer wall of the hydraulic regulating cylinder 9.2 is slidably sealed to the inner wall of the hydraulic cylinder cavity 17.2 by a second O-ring seal 10.2.

[0034] The hydraulic regulating cylinder 9.2 contains a pressure compensation chamber 14.2. A limiting inner edge 13.2 is located on the inner wall of the end of the hydraulic regulating cylinder 9.2 furthest from the transition chamber 18.2. A follower piston 11.2 is movably mounted within the pressure compensation chamber 14.2, and a pressure spring 15.2 is also located within it. The pressure spring 15.2 exerts a thrust along the axial direction on the follower piston 11.2, causing the follower piston 11.2 to press against the limiting inner edge 13.2. The end of the pressure compensation chamber 14.2 furthest from the follower piston 11.2 is connected to the hydraulic cylinder cavity 17.2 via a connecting hole 16.2. The system also includes an electric telescopic device 5.2. The telescopic rod 6.2 of the electric telescopic device 5.2 is parallel to the axis of the hydraulic regulating cylinder 9.2, and the end of the telescopic rod 6.2 is fixedly connected to the hydraulic regulating cylinder 9.2 via an arm 8.2.

[0035] Working method and principle: In the initial state, both the n hydraulic regulating cylinder 9.1 and the m hydraulic regulating cylinder 9.2 are in a fixed state; the control slider 26 moves back and forth periodically, and under the action of the synchronous beam 28, the n plunger 23.1 and the m plunger 23.2 move back and forth with the same frequency and amplitude in the n plunger pump body 3.1 and the m plunger body 3.2, respectively. This causes the n plunger pump body 3.1 and the m plunger body 3.2 to perform pumping actions at the same frequency, so that the n raw material output pipe 2.1 and the m raw material output pipe 2.1 continuously output the n raw material and the m raw material to the timely mixing and stirring unit, respectively.

[0036] Taking the n-plunger pump body 3.1 as the analytical counterpart, in one complete pumping cycle within the n-plunger pump body 3.1: after the n-plunger 23.1 moves to the right to the right end of the n-plunger pump body 3.1, the n-plunger 23.1 then moves to the left to the left end of the n-plunger pump body 3.1. Since the n-hydraulic regulating cylinder 9.1 is fixed, during the process of the n-plunger 23.1 moving to the right to the right end of the n-plunger pump body 3.1, the volume of the n-hydraulic cylinder cavity 17.1 gradually decreases, thereby causing the n-bulging cavity 24.1 formed between the n-elastic wall 21.1 and the n-baffle 19.1 to gradually increase to a certain value v1; subsequently, the n-plunger 23.1... As the pump moves to the right end of the n-piston pump body 3.1, the n-hydraulic cylinder 17.1 gradually increases in size, and the volume of the n-expansion chamber 24.1, which has a volume of v1, gradually decreases to zero. At this time, the m-hydraulic cylinder 17.2 enters a negative pressure state. The n-follower piston 11.1 will move to the left under the action of negative pressure, overcoming the n-pressure spring 15.1, thus playing a pressure compensation role and preventing the negative pressure in the n-hydraulic cylinder 17.1 from becoming too large. Therefore, in one complete pumping cycle in the n-piston pump body 3.1, the larger the value of v1, the smaller the value of the pumping volume w1 in one pumping cycle in the n-piston pump body 3.1.

[0037] Taking the m-plunger pump body 3.2 as the analytical target, in one complete pumping cycle within the m-plunger pump body 3.2: after the m-plunger 23.2 moves to the left to the left end of the m-plunger pump body 3.2, the m-plunger 23.2 then moves to the right to the right end of the m-plunger pump body 3.2; since the m-hydraulic regulating cylinder 9.2 is fixed, during the process of the m-plunger 23.2 moving to the left to the left end of the m-plunger pump body 3.2, the volume of the m-hydraulic cylinder cavity 17.2 will gradually decrease, thereby causing the m-bulging cavity 24.2 formed between the m-elastic wall 21.2 and the m-baffle 19.2 to gradually increase to a certain value v2; subsequently As plunger 23.2 moves to the right to the right end of plunger pump body 3.2, hydraulic cylinder 17.2 gradually increases in size, while the volume of expansion chamber 24.2 (volume v1) gradually decreases to zero. At this point, hydraulic cylinder 17.2 enters a negative pressure state. Under the negative pressure, follower piston 11.2 will overcome the pressure spring 15.2 and move to the right, thus providing pressure compensation and preventing excessive negative pressure in hydraulic cylinder 17.2. Therefore, in one complete pumping cycle within plunger pump body 3.2, the larger the value of v2, the smaller the pumping volume w2 in one pumping cycle within plunger pump body 3.2.

[0038] Since the internal working conditions and structure of both the n-plunger pump body 3.1 and the m-plunger body 3.2 are symmetrical in their original state, the values ​​of v1 and v2 are equal, and therefore the values ​​of w1 and w2 are always equal. Consequently, the proportions of n-material output pipe 2.1 and m-material output pipe 2.1 that export n-material and m-material to the mixing unit are always consistent and are not affected by the frequency of the periodic left-right back-and-forth movement of slider 26. The higher the frequency of the periodic left-right back-and-forth movement of slider 26, the faster the amount of n-material and m-material exported from n-material output pipe 2.1 and m-material output pipe 2.1 to the mixing unit will be.

[0039] To increase the discharge rate of raw material n relative to raw material m, thereby increasing the instantaneous mixing ratio of raw material n, it is only necessary to increase the pumping volume w1 of one pumping cycle within the n plunger pump body 3.1. The specific adjustment method is as follows: Control the n telescopic rod 6.1 to actively move to the right, causing the n hydraulic regulating cylinder 9.1 to move to the right a certain distance and then stop, thereby increasing the volume of the n hydraulic cylinder cavity 17.1 relative to the original state. At this time, taking the n plunger pump body 3.1 as the analysis counterpart, in one complete pumping cycle within the m plunger pump body 3.2, the value of v1 decreases relative to the original state, thereby increasing the value of w1; thus achieving the purpose of increasing the pumping volume w1 of one pumping cycle within the n plunger pump body 3.1; and the adjusted discharge ratio of raw material n to raw material m is not affected by the frequency of the periodic left-right reciprocating movement of the slider 26.

[0040] To increase the discharge rate of raw material m relative to raw material m, thereby increasing the instantaneous mixing ratio of raw material m, it is only necessary to increase the pumping volume w2 of one pumping cycle within the plunger pump body 3.2. The specific adjustment method is as follows: Control the telescopic rod 6.2 to actively move to the left, causing the hydraulic regulating cylinder 9.2 to move to the left a certain distance and then stop, thereby increasing the volume of the hydraulic cylinder cavity 17.2 relative to the original state. At this time, taking the plunger pump body 3.2 as the analysis counterpart, in one complete pumping cycle within the plunger pump body 3.2, the value of v2 decreases relative to the original state, thereby increasing the value of w2. This achieves the purpose of increasing the pumping volume w2 of one pumping cycle within the plunger pump body 3.2, and the adjusted discharge ratio of raw material n to raw material m is not affected by the frequency of the periodic left-right reciprocating movement of the slider 26.

[0041] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
