Specifically, the dimensions of the new vacuum mud kneading machine are 101 cm long × 34 cm wide × 76 cm high, weighing 80 kg, the torque of the stirring shaft 103 is 172 Nm, the speed is 48 turns per minute, and the mud output per hour is about 60 kg. The working voltage adopted by the present invention is a single-phase 220V, 50Hz power supply (common household AC voltage). The vacuum mud kneading machine 100 includes a motor cavity 107, a box 106 and an electrical control box 119. A switch door is provided on the side wall of the box 106. The motor cavity 107 is in the shape of a rectangular parallelepiped. The motor 104 is installed inside the motor cavity 107. The motor 104 is installed on the motor cavity support plate 124 through the motor mounting seat 125. The side wall of the motor cavity 107 is provided with a power supply interface for powering the motor 104. The output end of the motor 104 is connected to the motor output shaft 128, and the motor output shaft 128 passes through the vacuum chamber 102 and the stirring shaft 103. When the motor 104 rotates, it will drive the motor output shaft 128 to rotate. An exhaust hole is provided on the motor cavity support plate, that is, inside the vacuum chamber 102. The exhaust hole is connected to the vacuum pump 105 through an air pipe. The motor 104 is installed on one side wall of the motor cavity support plate 124, and the vacuum chamber 102 is installed on the other side. A vacuum chamber mud discharge port 116 is provided on the vacuum chamber 102, and a mud discharge port cover 117 is installed on the vacuum chamber mud discharge port 116. The mud discharge port cover 117 is covered on the mud discharge port cover 117 by a nylon part and a sealing gasket in a sealing snap-fit ​​manner to achieve a sealing effect (the negative pressure of the vacuum pump itself is used to make the mud discharge port cover more and more pressed to achieve effective sealing). Four lock buckles 126 are provided on the vacuum chamber 102. Because a small amount of mud will always be sucked into the vacuum chamber during each mud refining and vacuuming process, and it will increase over time. The function of the vacuum chamber mud discharge port is to regularly clean up the residual mud in the vacuum chamber.The mixing barrel 101 and the vacuum chamber 102 are connected by a sealing gasket lock, and the sealing effect is achieved by pre-tightening the lock. In order to facilitate the disassembly of the mixing barrel 101, four locking hooks 127 are also provided on the mixing barrel 101, and the positions of the locking hooks 127 correspond to the positions of the locks 126. When mud refining is required, the mixing barrel 101 and the vacuum chamber 102 are tightly buckled together through the locks 126. In order to facilitate the placement of mud into the mixing barrel 101, an outwardly protruding mud inlet 114 is opened above the mixing barrel 101, and a mud throwing port cover 115 is installed above the mud inlet 114. The mud throwing port cover 115 is locked and connected to the mud inlet 114. A circular concave hole is provided at the front end of the mixing shaft 103 close to the motor output shaft 128, and the diameter of the concave hole is larger than the diameter of the motor output shaft 128. When connected, the mixing shaft 103 is sleeved on the motor output shaft 128 and fixed by bolts, and the cylindrical hole is used for positioning and the hexagonal The bolt passes through the stirring shaft 103 and the motor output shaft 128, and the torque is transmitted by the cylindrical hole and the six-sided spline groove. The motor output shaft 128 is detachably connected to the stirring shaft 103 by screws. For better stirring, a stirring rod 108, a spiral mud squeezing piece 109 and a mud breaking piece 110 are installed on the stirring shaft 103. The mud breaking piece can squeeze and cut off the mud sent by the spiral blade during the extrusion of the mud, which can make the mud more delicate and the finished mud smoother. The stirring rod 108 is arranged to be installed at the front end of the stirring shaft 103 at the stirring barrel 101. The stirring rod 108 is arranged in multiple shapes. The stirring rod 108 is in a "T-shaped" shape and is installed on the stirring shaft 103. The spiral mud squeezing piece 109 and the mud breaking piece 110 are arranged to be installed at the rear end mud outlet hole 112 of the stirring shaft 103, and the spiral mud squeezing piece 109 and the mud breaking piece 110 are arranged in the conical barrel 111.When in use, when mud is put into the mixing barrel 101 through the mud inlet 114, the motor 104 and the vacuum pump 105 are started, and the motor 104 starts to drive the motor output shaft 128 to rotate. The motor output shaft 128 rotates and drives the mixing shaft 103 to rotate. At this time, the mixing rod 108 on the mixing shaft 103 will mix the mud, and then the mud will move forward along the rotation direction of the mixing shaft 103 into the conical barrel 111. When the mud moves to the position of the spiral mud squeezing piece 109, the spiral mud squeezing piece 109 will bring the stirred mud to the mud outlet 112 position, and the mud outlet 112 position is installed with a screw. Install the mud hole cover, which is stuck on the mud hole 112. The mud hole cover is covered on the mud hole in a sealed snap-fit ​​manner through nylon parts and sealing gaskets to achieve a sealing effect (the negative pressure of the vacuum pump itself is used to make the mud hole cover effectively sealed). When the mud reaches the mud hole 112, it will push the mud hole cover open and come out of the mud hole 112. The extrusion pressure is much greater than the negative pressure in the mixing barrel. The mud after coming out will fall onto the roller bracket 113, and the mud will push the roller forward. The roller bracket 113 is installed on the surface of the box 106. The relevant staff can cut the mud through the mud cutting line to check the condition of the mud. In order to facilitate the cleaning of mud on the outer wall of the vacuum chamber, a scraper is installed on the outer wall. The scraper is set above the connection between the stirring shaft 103 and the motor output shaft 128. The scraper can scrape the mud adhered to the outer wall of the vacuum chamber clean. The vacuum mud kneading machine can be cleaned after use by disassembling the stirring barrel 101. First, loosen the lock of the mud port cover 115, remove the mud port cover 115, and place it on the ground; then loosen the lock of the vacuum chamber, remove the stirring barrel 101, and then use a tool to unscrew the bolts at the connection between the stirring shaft 103 and the motor output shaft 128, remove the stirring shaft 103, place it on the ground and clean it with a matching scraper.

[0029] The stirring barrel 101 and the vacuum chamber 102 are both arranged above the box body 106. Sealing gaskets are provided at the connections between the stirring barrel 101, the vacuum chamber 102 and the motor cavity support plate 124. The box body 106 is a rectangular parallelepiped with an internal hollow structure. A guide rail is fixedly installed on the bottom plane inside the box body 106. A vacuum pump 105 is fixedly installed next to the guide rail. The vacuum pump 105 is electrically connected to the air switch. A frequency converter, a power module, a leakage protector and a relay are installed on the guide rail. The vacuum pump, the frequency converter, the power module, the leakage protector, the relay, the air switch are electrically connected to the control circuit board in the electrical control box. The electrical control box is installed above the motor cavity. The control circuit board and a display screen 120 are installed in the electrical control box. An operating switch 121 is installed below the display screen 120, and a knob 122 and an emergency stop switch 123 are installed above the display screen 120. The display screen 120 receives the output signal of the control circuit board and displays the result; the liquid crystal display screen can prompt the progress of mud kneading in real time, clearly know the status of the mud kneading machine, and meet the control requirements of the whole process of mud kneading. The product has beautiful appearance and low noise, uses 220V AC input, and meets the use requirements of general studios. The state of the vacuum pump can be adjusted by knob 122, such as "vacuum or pressure relief". When encountering an emergency, the emergency stop switch 123 can be pressed to prevent unnecessary losses. In order to facilitate the movement of the mud kneading machine, a self-locking universal wheel 118 is installed on the bottom plane of the box 106. Because the present invention is small and practical, it can be placed where it is needed according to the usage. The vacuum pump 105 used in the present invention is an oil-free vacuum pump with a vacuum rate of 110L / min and a vacuum degree of ≥0.09MPa. A sensor is installed inside the vacuum chamber 102. The sensor is an MPC series capacitive sensor. The sensor collects the pressure data in the vacuum chamber 102 and displays it on the display screen. In addition, different vacuum requirements can be selected according to different mud materials. The lowest air pressure that the mud material can reach in the vacuum chamber 102 is -0.085MPa; and there are multiple gears of -0.02MPa, -0.04MPa, and -0.06MPa to choose from, in order to adapt to different mud materials. The mud outlet 112 is designed as a circular mouth with a diameter of 80mm, which can be replaced with an inscribed triangle mud outlet 112 according to demand. The motor 104 uses a 142-type 1.5kw right-angle hollow reduction motor. At the same time, in order to improve the safety of the mud kneading machine operation, if the mud inlet cover 115 is not covered or locked, start the motor 104 or the vacuum pump 105, the motor 104 and the vacuum pump 105 will stop working and issue a warning sound. If the mud making machine is in operation and the mud injection port cover 115 is removed, the motor 104 and the vacuum pump 105 will stop and a warning sound will be issued.

[0030] In summary, the present invention has the characteristics of wide application range of clay materials, adjustable vacuum degree, good human-computer interaction, convenient and fast disassembly and cleaning. It is suitable for various types of clay materials, including but not limited to pottery clay, porcelain clay, purple clay materials, etc., to meet the needs of different industries.
