Description

Technical Field

[0001] The utility model relates to the technical field of ceramic production, in particular to a ceramic powder spray tower. Background Art

[0002] The spray tower plays the role of continuous drying of wet materials in the ceramic production industry. That is, the slurry wet material is pumped into the spray tower pipe by the screw pump, and evenly sprayed down from the nozzle to the upper end of the pipe. Then, the spray tower is matched with a certain high temperature to instantly atomize and dry the wet material into powder and drop it to the bottom of the spray tower. In the current spray tower production process, after the powder is sprayed out from the nozzle of the spray gun, the dust often accumulates on the spray gun's spray rod, or agglomerates on the periphery of the spray gun's nozzle, causing the spray gun to be easily blocked or the atomization effect to be poor. Once this phenomenon occurs, it is often necessary to stop the spray tower's powder spraying work, and then manually check which pipe is blocked, or manually repair it. It is necessary to use a hammer to knock the spray gun pipe to let the blocked powder and mud fall off, but this will seriously affect the drying efficiency, and the knocking after long-term blockage will also cause damage to the pipe, thereby shortening the life of the spray tower.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0030] The following is combined with Figures 1 to 3 The technical solution of the utility model is further illustrated by specific implementation methods.

[0031] The utility model provides a ceramic powder spray tower, comprising a tower 1, a plurality of spray guns 2, a plurality of drive devices 3, a limit assembly 43 and a control module, wherein the side wall of the tower 1 is provided with an observation window 11;

[0032] A plurality of spray guns 2 are arranged in an array along the circumference of the tower 1. The spray guns 2 include a gun barrel 21 and a nozzle 22. The gun barrel 21 is detachably and limitably disposed in the tower 1 through the limiting assembly 43. The output end of the gun barrel 21 is inserted into the side wall of the tower 1 and is located inside the tower 1. The output end of the gun barrel 21 is connected to the nozzle 22.

[0033] A driving device 3 is correspondingly connected to a spray gun 2, and the driving device 3 is used to drive the spray gun 2 to reciprocate so that the gun barrel 21 moves on the tower 1;

[0034] The plurality of driving devices 3 are electrically connected to the control module respectively, and the control module is used to control the start and stop states of the driving devices 3 .

[0035] Multiple spray guns 2 are arranged in an array around the tower 1. The multiple spray guns 2 are used to spray the slurry at the same time, thereby improving the efficiency of powder making. The spray gun 2 is connected to the driving device 3, and the driving device 3 is used to drive the spray gun 2 to shake, so that the accumulated powder mass falls from the nozzle 22. In addition, the gun barrel 21 is detachably mounted on the tower 1 through the limit assembly 43, and is movably arranged in the tower 1 in a limit position, so that when the spray gun 2 moves back and forth relative to the tower 1 under the drive of the driving device 3, the range of movement is limited by the limit assembly 43 to prevent the spray gun 2 from leaving the tower 1. Each driving device 3 is electrically connected to the control module. Specifically, the operator observes the inside of the tower 1 from the observation window 11. When it is found that the nozzle 22 of a spray gun 2 has serious powder accumulation, the control module controls the driving device 3 of the spray gun 2 to operate accordingly, and the spray gun 2 is shaken to avoid excessive accumulation of powder mass at the nozzle 22 and the occurrence of false particles, thereby improving the particle grading and product quality of the powder. The utility model improves the efficiency of powder making by arranging a plurality of spray guns 2 in an array on the circumference of the tower 1 to spray the mud at the same time; each spray gun 2 is respectively connected to the corresponding driving device 3, and the corresponding driving device 3 can be controlled by the control module to drive the spray gun 2 to shake, so that the accumulated powder mass falls from the nozzle 22, so as to avoid the accumulation of powder mass on the nozzle 22 affecting the powder spraying, powder making effect and powder making efficiency; at the same time, the moving range of the spray gun 2 can be limited by the limit component 43, so as to avoid the spray gun 2 moving range being too wide, making it difficult to recover, and making it impossible to continue to implement the vibration powder shaking of the spray gun 2.

[0036] Furthermore, the driving device 3 is disposed on the outer side wall of the tower 1 , and the driving end of the driving device 3 is detachably connected to the gun barrel 21 , and the driving device 3 is used to drive the gun barrel 21 to reciprocate along the axial direction of the gun barrel 21 .

[0037] The driving device 3 is arranged outside the tower 1 for easy installation and maintenance. To further explain, the driving device 3 drives the gun barrel 21 to reciprocate along its axial direction, thereby driving the spray gun 2 to reciprocate, and the nozzle 22 of the spray gun 2 will vibrate during the movement, and the powder mass accumulated on the nozzle 22 is shaken off by continuous vibration, thereby improving the particle size distribution of the powder and the product quality.

[0038] Furthermore, it also includes a plurality of guide sliding components 4 arranged on the outer side wall of the tower 1, and one of the guide sliding components 4 is arranged corresponding to one of the spray guns 2;

[0039] The guiding and sliding assembly 4 includes a sliding mechanism 41, a slide rail 42 and the limiting assembly 43 which cooperate with each other. The sliding mechanism 41 is connected to the gun barrel 21. The slide rail 42 is fixedly arranged on the outer side wall of the tower barrel 1. The slide rail 42 extends in a direction away from the tower barrel 1. The limiting assembly 43 is detachably arranged at one end of the slide rail 42 away from the tower barrel 1. The limiting assembly 43 is used to limit the sliding mechanism 41 from detaching from the slide rail 42.

[0040] The sliding mechanism 41 is connected to the gun barrel 21. The slide rail 42 is fixedly arranged on the outer side wall of the tower barrel 1. When the driving device 3 drives the spray gun 2 to reciprocate, the sliding mechanism 41 reciprocates along the extending direction of the slide rail 42, avoiding the position deviation of the spray gun 2 during reciprocating movement. A limiting assembly 43 is detachably arranged at one end of the slide rail 42 away from the tower barrel 1, preventing the spray gun 2 from detaching from the end of the slide rail 42 and causing damage to the driving device 3 and the spray gun 2.

[0041] Furthermore, the vertical section of the slide rail 42 is in a U-shaped structure;

[0042] The sliding mechanism 41 includes a mounting frame 411 and a plurality of guide pulleys 412. The mounting frame 411 is connected to the spray gun 2. The guide pulleys 412 are rotatably arranged on both sides of the bottom of the mounting frame 411. The guide pulleys 412 slide along the slide rail 42.

[0043] Since a certain amount of dust will be generated in the ceramic production workshop, if the sliding mechanism 41 is directly installed on the slide rail 42, after long-term use, the slide rail 42 being covered with dust may cause the sliding mechanism 41 to slide不畅. By rotatably arranging a plurality of guide pulleys 412 at the bottom of the mounting frame 411, smooth sliding is achieved through the contact between the guide pulleys 412 and the slide rail 42. Once the guide pulleys 412 are damaged or cannot work, only the guide pulleys 412 need to be replaced to resume work. In addition, the vertical section of the slide rail 42 is in a U-shaped structure, and the two side walls of the slide rail 42 play a role in limiting the guide pulleys 412, ensuring that the sliding mechanism 41 does not derail from both sides of the slide rail 42.

[0044] Furthermore, limiting parts 421 which bend inward are arranged at the tops of the two side walls of the slide rail 42. The limiting parts 421 are adapted to the guide pulleys 412.

[0045] On the one hand, the limiting parts 421 are adapted to the guide pulleys 412 to limit the sliding position of the guide pulleys 412 and avoid the guide pulleys 412 from derailing from the top of the slide rail 42. On the other hand, the limiting parts 421 are located at the tops of the guide pulleys 412 and can also prevent dust from falling onto the path (slide rail 42) where the guide pulleys 412 work.

[0046] Furthermore, the limiting assembly 43 is a bolt, the slide rail 42 is provided with a threaded hole penetrating therethrough, and the bolt is used in conjunction with the threaded hole.

[0047] The limiting component 43 is a bolt, and a threaded hole is provided at the end of the slide rail 42 (equivalent to the end of the slide rail 42 away from the tower 1). By passing the bolt through the threaded hole, the bolt is vertically set at the end of the slide rail 42 to prevent the sliding mechanism 41 from derailing from the end of the slide rail 42, so that the guide pulley 412 cannot slide normally after detaching from the slide rail 42.

[0048] Furthermore, the driving device 3 is a cylinder, and the moving direction of the piston rod 31 of the cylinder is perpendicular to the side wall of the tower 1;

[0049] The gun barrel 21 is provided with a connecting arm 23 extending vertically upward, and the top of the connecting arm 23 is detachably connected to the piston rod 31 of the cylinder;

[0050] The sliding mechanism 41 is disposed at the bottom of the gun barrel 21 .

[0051] The driving device 3 and the guide sliding assembly 4 are respectively arranged on both sides of the gun barrel 21. Specifically, the cylinder is arranged on the upper part of the gun barrel 21, and the guide sliding assembly 4 is arranged on the lower part of the gun barrel 21, and the two are arranged opposite to each other.

[0052] The top of the gun barrel 21 is provided with a connecting arm 23 extending upward, and the upper end of the connecting arm 23 is connected to the piston rod 31 of the cylinder; the bottom of the gun barrel 21 is connected to the sliding mechanism 41, and the sliding mechanism 41 slides in cooperation with the slide rail 42. When the piston rod 31 of the cylinder is extended and retracted, the gun barrel 21 is driven to move back and forth along the direction of the slide rail 42 through the connecting arm 23. The specific working principle is as follows: the piston rod 31 of the cylinder drives the connecting arm 23 to move, and the spray gun 2 and the sliding mechanism 41 under the connecting arm 23 move accordingly. When the piston rod 31 extends, the connecting arm 23 drives the spray gun 2, and the spray gun 2 drives the sliding mechanism 41 to move in the direction away from the tower 1; when the piston rod 31 retracts, the connecting arm 23 drives the spray gun 2, and the spray gun 2 drives the sliding mechanism 41 to move in the direction close to the tower 1, so as to achieve reciprocating movement (shaking).

[0053] Furthermore, the piston rod 31 of the cylinder is provided with a U-shaped head 32, and the U-shaped head 32 includes a mounting plate and two mounting arms 321. One side of the mounting plate is connected to the piston rod 31 of the cylinder, and the two mounting arms 321 are arranged parallel to each other on the other side of the mounting plate. The two mounting arms 322 are respectively provided with corresponding mounting holes, and the top of the connecting arm 23 is provided with a connecting hole 231. The U-shaped head 32 and the connecting arm 23 are installed by passing a screw through the mounting hole and the connecting hole 231.

[0054] The piston rod 31 is connected to a U-shaped head 32, which is composed of a mounting plate and two mounting arms 321, and the connection part of the connecting arm 23 is between the two mounting arms 321. The two mounting arms 321 are respectively provided with mounting holes, and the top of the connecting arm 23 is provided with a connecting hole 231. When the connecting arm 23 is in the connection part, the screw rod passes through the mounting hole and the connecting hole 231 respectively, so as to realize the installation connection of the connecting arm 23 and the piston rod 31. The driving device 3 and the spray gun 2 are detachable from each other, which can be more convenient to install and maintain.

[0055] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
