Description

Technical Field

[0001] The invention relates to the technical field of zinc stearate production, in particular to a nozzle assembly for synthesizing particles by a melting method. Background Art

[0002] When producing granular zinc stearate, first, stearic acid is heated to a temperature above the melting point of zinc stearate, that is, in a molten state, and zinc oxide is directly added. Under the action of a catalyst, the reaction temperature, pressure and stirring speed are controlled to allow them to fully react. The mixture is then sprayed out through a nozzle and cooled to obtain granular zinc stearate.

[0003] The disadvantage of the prior art is that, when producing granular zinc stearate, the zinc stearate sprayed from the nozzle connected to the pipeline is of fixed specifications. Due to the high requirements for the preparation of zinc stearate particles, particles of different sizes need to be produced. Therefore, when producing granular zinc stearate of different specifications, different production equipment must be selected, which increases production costs accordingly. Therefore, those skilled in the art have provided a nozzle assembly for melt-synthesized particles to address the problems raised in the above background art. Summary of the Invention

[0010] As a further description of the above technical solution: each of the nozzles is provided with a protrusion adapted to the sealing member, and the discharge port is provided with a slot for the protrusion to be inserted.

[0011] As a further description of the above technical solution: the first disc is rotatably arranged on the pipeline through a bearing seal, and the liquid inlet of each of the nozzles is located in the first disc.

[0012] As a further description of the above technical solution: the second disc is driven by a driving member, and the driving member includes a motor and a transmission assembly arranged on the box.

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments.

[0033] See also Figure 1-9 The embodiment of the present invention provides a technical solution: a nozzle assembly for synthesizing particles by a melt method, which is arranged in a box body 1, including a pipe 2, a discharge port 3 is opened on the pipe 2, and also includes a first disc 4 rotatably arranged on the pipe 2, and the first disc 4 corresponds to the discharge port 3, and a plurality of nozzles 5 are equidistantly arranged on the circumference of the first disc 4, each nozzle 5 slides along the radial direction of the first disc 4, and the liquid inlet of each nozzle 5 can be connected with the discharge port 3; a second disc 6 is rotatably arranged on one side of the first disc 4, and an extrusion piece is arranged on the second disc 6; when the second disc 6 rotates, the extrusion piece drives each nozzle 5 to rotate, so that each nozzle 5 can be selectively connected with the discharge port 3.

[0034] Specifically, one end of the pipe 2 extends out of the outside of the box body 1 and is connected to the molten zinc stearate. Air ducts 14 are provided on both sides of the box body 1. The air ducts 14 are connected to the air cooler, and a discharge port 15 is provided at the bottom of the box body 1. The air cooler blows cold air into the box body 1 through the air duct 14 to cool the molten zinc stearate sprayed from the nozzle 5 to obtain granular zinc stearate. The first disc 4 is sleeved on the outside of the discharge port 3, so that each nozzle 5 is arranged around the discharge port 3. A sealed space is formed between the first disc 4 and the discharge port 3, so that the liquid inlet of each nozzle 5 is located in the sealed space, avoiding the liquid inlets of other unused nozzles 5 from being exposed in the box body 1, so as to prevent the molten zinc stearate sprayed from the nozzle 5 from entering the liquid inlets of other unused nozzles 5 during zinc stearate production. The droplets sprayed by each nozzle 5 are different in size, so that it can adapt to the production of granular zinc stearate of different specifications. The surface of each nozzle 5 is marked with specifications, and the box 1 is provided with a visualization window on the surface, through which the specifications and sizes of the nozzles 5 connected to the discharge port 3 can be observed. When the nozzles 5 rotate to the position of the discharge port 3, they are connected to the discharge port 3. The user can select the nozzles 5 of corresponding specifications to be connected to the discharge port 3 according to production requirements. The first disc 4 is rotatably connected to the pipe 2, and the second disc 6 is rotatably connected to the first disc 4. The extrusion piece is fixedly provided on the second disc 6 and rotates synchronously with the second disc 6. The number of extrusion pieces is the same as the number of nozzles 5, so that each extrusion piece can extrude the corresponding nozzle 5 respectively. When the second disc 6 rotates, the nozzles 5 are driven to rotate by the extrusion piece to realize that each nozzle 5 is selectively connected to the discharge port 3, that is, when the second disc 6 rotates, the nozzles 5 can be driven to rotate by the extrusion piece, so that the nozzles 5 of the required specifications and sizes are connected to the discharge port 3, thereby changing the size of the droplets sprayed by the nozzles 5 to obtain zinc stearate particles of the required specifications and sizes.

[0035] The present invention arranges multiple nozzles 5 on the first disc 4, and cooperates with the second disc 6 and the extrusion piece. When the second disc 6 is rotated, the extrusion piece is driven to rotate, so that the extrusion piece can squeeze the nozzle head 5 to rotate, so that each nozzle head 5 is selectively connected to the discharge port 3, thereby realizing the switching of nozzle heads 5 of different specifications to adapt to the production of granular zinc stearate of different specifications, greatly saving production costs. In addition, in this design, the liquid inlet of each nozzle head 5 is located in a sealed space, which can avoid the liquid inlets of other unused nozzle heads 5 from being exposed in the box body 1, so as to prevent the zinc stearate melt sprayed from the nozzle head 5 from entering the liquid inlets of other unused nozzle heads 5 during zinc stearate production, greatly reducing the problem of clogging of other nozzle heads 5.

[0036] In another embodiment provided by the present invention, an inclined groove 8 adapted to the extrusion piece is provided on the nozzle 5. When the second disc 6 rotates, the extrusion piece enters the inclined groove 8, and the extrusion nozzle 5 slides along the radial direction of the first disc 4, so that the nozzle 5 is separated from the discharge port 3 and rotates synchronously with the second disc 6 to switch the nozzle 5. In this design, each nozzle 5 can slide along the radial direction of the first disc 4, so that when each nozzle 5 is switched, it can first slide along the radial direction of the first disc 4 to separate from the discharge port 3, and then rotate and switch, avoiding direct rotation of the nozzle 5 and friction between the seal 9, and preventing the seal 9 from being squeezed, deformed, or dislocated when the nozzle 5 is switched, thereby affecting the sealing effect. That is, this design can prevent the seal 9 from being squeezed and deformed while realizing the switching of the nozzle 5.

[0037] Specifically, when the second disc 6 rotates, the extrusion piece rotates synchronously with the second disc 6. When the extrusion piece rotates to enter the chute 8, as the second disc 6 continues to rotate, each extrusion piece continuously squeezes each nozzle 5, causing the nozzle 5 to slide along the radial direction of the first disc 4. At this time, the nozzle 5 connected to the discharge port 3 moves downward (refer to Figure 8 ) so that the nozzle 5 connected to the discharge port 3 is separated from the discharge port 3. During this process, the second disc 6 continues to rotate. At this time, the extrusion nozzle 5 of the extrusion part rotates synchronously with the second disc 6 to realize the switching of nozzles 5 of different specifications until the nozzle 5 of the required specification is switched.

[0038] In another embodiment provided by the present invention, the extrusion member is a latch 7. Specifically, the latch 7 is adapted to the inclined slot 8 and can be inserted into the inclined slot 8 when the second disc 6 rotates forward, thereby squeezing the nozzle 5 to cause the nozzle 5 to rotate. When the second disc 6 reverses, the latch 7 synchronously reverses and disengages from the inclined slot 8.

[0039] In another embodiment provided by the present invention, an elastic member 10 is sleeved on the outer side of the nozzle 5. The elastic force of the elastic member 10 causes the nozzle 5 to press against the discharge port 3 for sealing. Specifically, the elastic member 10 is a tension spring, which is arranged in the first disc 4. When the pressure of the nozzle 5 disappears, that is, when the pin 7 disengages from the inclined groove 8 and the nozzle 5 loses the extrusion of the extrusion member, the nozzle 5 is pulled to slide and reset along the radial direction of the first disc 4, that is, each nozzle 5 slides toward the direction of the pipeline 2. At the same time, the elastic force of the elastic member 10 can press the nozzle 5 against the discharge port 3 when the nozzle 5 is connected with the discharge port 3, thereby realizing the sealed connection between the nozzle 5 and the discharge port 3.

[0040] In another embodiment provided by the present invention, a seal 9 is provided in the discharge port 3. The seal 9 is a sealing ring. The seal 9 is pressed against the discharge port 3 under the elastic force of the elastic member 10 to achieve sealing between the nozzle 5 and the discharge port 3.

[0041] In another embodiment provided by the present invention, each nozzle 5 is provided with a protrusion 51 that is compatible with the seal 9, and a slot for inserting the protrusion 51 is opened on the discharge port 3, and the seal 9 is arranged in the slot. Specifically, when the nozzle 5 is connected with the discharge port 3, the protrusion 51 on the nozzle 5 is inserted into the slot on the discharge port 3 and pressed against the seal 9 to improve the sealing effect.

[0042] In another embodiment provided by the present invention, the first disc 4 is rotatably mounted on the pipe 2 via a bearing 41, and the liquid inlet of each nozzle 5 is located within the first disc 4. This can prevent the liquid inlets of other unused nozzles 5 from being exposed within the housing 1, thereby preventing the zinc stearate melt sprayed from the nozzle 5 during zinc stearate production from entering the liquid inlets of other unused nozzles 5, thereby greatly reducing the problem of clogging of other nozzles 5.

[0043] In another embodiment provided by the present invention, the second disc 6 is driven by a driving member, which includes a motor 11 and a transmission assembly arranged on the box body 1. Specifically, the motor 11 is a forward and reverse motor, so that the second disc 6 can rotate both forward and reverse. When the motor 11 is working, it drives the second disc 6 to rotate through the transmission assembly.

[0044] In another embodiment provided by the present invention, the transmission assembly includes a second pulley 12 sleeved on the output shaft of the motor 11 and a first pulley 61 arranged on the second disc 6, and a belt 13 is arranged between the second pulley 12 and the first pulley 61. Specifically, when the motor 11 rotates forward, it drives the second pulley 12 to rotate, and then drives the first pulley 61 to rotate through the belt 13, thereby realizing the forward rotation of the second disc 6. Similarly, when the motor 11 rotates reversely, the second disc 6 reverses.

[0045] In another embodiment provided by the present invention, a ball is provided on the pin 7, so that the pin 7 can roll along the inclined groove 8, reducing the friction between the pin 7 and the inclined groove 8. A limiting groove adapted to the ball is provided in the inclined groove 8. After the pin 7 is inserted into the inclined groove 8, it is stuck in the limiting groove, so that the pin 7 drives the nozzle 5 to rotate more stably.

[0046] During the production of zinc stearate, the molten zinc stearate enters the nozzle 5 connected to the discharge port 3 through the discharge port 3 on the pipe 2, and is sprayed into the box body 1 through the nozzle 5. At the same time, the air duct 14 is connected to the cold air blower, and cold air is blown into the box body 1 through the air duct 14 to cool the molten zinc stearate sprayed from the nozzle 5 to obtain granular zinc stearate, which flows out through the discharge port 15. When it is necessary to adjust the nozzle 5 to produce granular zinc stearate of different specifications, the pipe 2 stops feeding, and the motor 11 is driven to rotate the second pulley 12, and then the first pulley 61 is driven to rotate through the belt 13, so that the second disc 6 rotates forward synchronously. When the second disc 6 rotates forward (reference Figure 6), the latch 7 rotates synchronously with the second disc 6. During this process, the latch 7 gradually rotates into the inclined slot 8. As the second disc 6 continues to rotate, the latches 7 continuously squeeze the nozzles 5, causing the nozzles 5 to slide along the radial direction of the first disc 4, that is, the nozzles 5 slide along the radial direction of the first disc 4 in a direction away from the pipe 2 (such as Figure 8 As shown), at this time, the latch 7 is located in the limit groove, and the nozzle 5 connected to the discharge port 3 is separated from the discharge port 3. As the second disc 6 continues to rotate, each latch 7 squeezes the corresponding nozzle 5, driving each nozzle 5 to rotate synchronously with the second disc 6. The specification markings on the nozzle 5 are observed through the visual window until the nozzle 5 of the required specification rotates to the position of the discharge port 3. The second disc 6 stops rotating forward. Then, similarly, when the motor 11 is reversed, the second disc 6 is driven to rotate backward (refer to the attached Figure 8 ), when the second disc 6 reverses, the latch 7 reverses synchronously with the second disc 6, and disengages from the chute 8 from the limit slot, and the second disc 6 stops rotating. When the latch 7 disengages from the chute 8 (as Figure 6 As described above, that is, when the nozzle 5 loses the extrusion of the extrusion member, the elastic restoring force of the elastic member 10 pulls the nozzle 5 to slide and reset along the radial direction of the first disc 4, that is, each nozzle 5 slides toward the direction of the pipe 2. At this time, the nozzle 5 corresponding to the discharge port 3, that is, the nozzle 5 of the required specification is connected to the discharge port 3. At the same time, the elastic force of the elastic member 10 can insert the protrusion 51 on the nozzle 5 connected to the discharge port 3 into the groove on the discharge port 3, and press it against the sealing member 9 to achieve the sealing between the nozzle 5 and the discharge port 3, that is, to achieve the switching of nozzles 5 of different specifications, and to be able to produce granular zinc stearate of different sizes.

[0047] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
