Description

Technical Field

[0001] The present application relates to the technical field of casserole production, and specifically discloses a mud mixing device for casserole production. Background Art

[0002] Sand pots are ceramic products made of quartz, feldspar, clay and other materials that are not easy to conduct heat. They are fired at high temperatures and have the characteristics of air permeability, adsorption, uniform heat transfer, and slow heat dissipation. The main raw materials of sand pots include clay, kaolin, quartz sand, feldspar, limestone powder, clay and other possible additives. These raw materials need to be mixed in a certain proportion to ensure that the final product has suitable physical and chemical properties.

[0003] In the production process of clay pots, it is necessary to first grind various raw materials into mud, and then filter them before evenly mixing them. However, with the expansion of the production scale, the distance between raw material grinding and mud mixing vehicle frame is relatively far. During the transportation of the ground raw materials, the raw materials are affected by air moisture and their own gravity extrusion and are prone to different degrees of agglomeration. This phenomenon is particularly obvious in humid areas. The current way to deal with this phenomenon is usually to manually break up the raw materials before mixing. This treatment method not only has high labor intensity and poor working environment, but also can only have a good treatment effect on the agglomeration of large particles. It has a poor treatment effect on the agglomeration of small particles in the raw materials. Some small particles agglomerate directly into the mixer, which affects the uniformity of mixing of various raw materials, thereby reducing the quality of clay pot products. Therefore, in view of this, the inventor provides a mud mixing device for clay pot production to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that in the production process of traditional clay pots, some small particles agglomerate and directly enter the mixer, which affects the uniformity of mixing various raw materials and thus reduces the quality of clay pot products.

[0005] In order to achieve the above object, the basic scheme of the present invention provides a mud mixing device for casserole production, comprising:

[0006] A mixing tank, wherein a feed pipe is provided at the top of the mixing tank and a discharge pipe is provided at the bottom of the mixing tank;

[0007] The mixing assembly includes a main shaft rotatably connected to the mixing tank, a stirring blade driven to rotate by the main shaft, and a driving mechanism driving the main shaft to rotate;

[0008] A screen disposed in the mixing tank;

[0009] The crushing assembly includes a collar arranged on the side wall of the main shaft and located above the screen, a plurality of rotating shafts arranged on the collar, and a plurality of rollers respectively arranged on each rotating shaft and rolling along the surface of the screen. An adjusting gear is arranged at the end of the rotating shaft, and a toothed disc meshing with the adjusting gear is arranged in the mixing tank.

[0010] The principles and effects of this basic solution are:

[0011] Compared with the prior art, the present invention arranges a screen and a roller in the mixing tank, so that when the main shaft drives the stirring blades to rotate to mix the materials, it also drives the sleeve and the rotating shaft to rotate in the plane. During the rotation of the two rotating shafts in the plane, the meshing between the gear and the toothed disk is adjusted to make the rotating shaft rotate vertically, thereby driving the roller to rotate, so that when small particles agglomerate into the mixing tank, they stay on the screen and are squeezed and broken by the roller, thereby avoiding the small particles agglomerating directly mixing with other raw materials and affecting the uniformity of mixing of various raw materials. At the same time, it can avoid the problem of local overheating or incomplete sintering caused by different particle sizes in the subsequent sintering process.

[0012] Furthermore, the inner wall of the mixing tank is provided with a partition, the adjusting gear and the toothed disc are both arranged in the partition, and the rotating shaft is provided with a rotating ring connected along the partition to avoid rotation. This arrangement prevents the mixed raw materials such as limestone powder and clay from contacting the toothed disc and the adjusting gear to affect the performance of the toothed disc and the adjusting gear.

[0013] Furthermore, a retaining ring is provided in the partition layer, and the retaining ring divides the partition layer into a transmission chamber and a heat preservation chamber, and the outer wall of the mixing tank is provided with a liquid inlet pipe and a liquid outlet pipe connected to the heat preservation chamber, so as to ensure that the materials in the mixing tank are in a suitable temperature environment when being mixed.

[0014] Furthermore, a spiral guide vane is provided in the heat preservation chamber, and the spiral guide vane guides the liquid in the heat preservation chamber.

[0015] Furthermore, the crushing assembly is also arranged below the screen, and the rollers of the two crushing assemblies are located in the same vertical plane and rotate relative to each other. With this arrangement, the roller below the screen can support the roller above the screen, avoiding the formation of a gap between the upper roller and the screen to affect the crushing effect of the agglomerated particles, and making the overall transmission structure more compact.

[0016] Furthermore, the top and bottom of the toothed disc are respectively provided with latching teeth meshing with the adjusting gear, thereby further improving the compactness of the transmission.

[0017] Furthermore, a rotating sleeve rotatably connected to the main shaft is provided in the middle of the screen, a fixed sleeve located inside the rotating sleeve is provided on the side wall of the rotating shaft, a plurality of spring guide plugs are provided at the peripheral end of the fixed sleeve, and a stepped surface matching with the spring guide plug is provided on the end surface of the screen located inside the rotating sleeve. With this arrangement, the fixed sleeve is driven to rotate during the rotation of the main shaft, so that the spring guide plug contacts the stepped surface, so that the spring guide plug is repeatedly compressed and released, and then hits the screen, so that the screen produces an oscillating effect, thereby preventing materials from accumulating on the screen.

[0018] Furthermore, the step surface includes a smoothly transitioning arc surface and a cliff surface connected to the arc surface, and the arc surface and the cliff surface are arranged alternately. The spring guide plug is gradually compressed when it contacts the arc surface, and is released when it reaches the cliff surface, thereby hitting the screen to cause the screen to vibrate.

[0019] Furthermore, the fixed sleeve is provided with a plurality of guide holes at the peripheral end, and the spring guide plug includes a reset spring arranged in the guide hole and a clamping bead connected to the reset spring. The reset spring is squeezed by the combination of the clamping bead and the arc surface, and when the clamping bead reaches the cliff surface, the elastic potential energy of the reset spring is used to release the clamping bead to hit the screen.

[0020] Furthermore, a discharge bin is provided at the bottom of the mixing tank, the discharge pipe is provided on one side wall of the discharge bin, a linear drive is provided on the other side wall of the discharge bin, the output shaft of the linear drive extends into the discharge bin and is provided with a piston which is slidably and sealably connected to the inner wall of the discharge bin. With this arrangement, the linear drive is used to drive the piston to move, thereby pushing the mixed material in the discharge bin to the discharge pipe for the next step of processing.

[0030] A mud mixing device for casserole production, for example Figure 1 As shown: it includes a mixing tank 1, a screen 14 arranged in the mixing tank 1, a mixing component and a crushing component.

[0031] A first feed pipe 3 and a second feed pipe 4 are respectively provided on the top of the mixing tank 1 for different raw materials to enter. A discharge bin 2 is provided at the bottom of the mixing tank 1. A discharge pipe 5 is provided on one side wall of the discharge bin 2. A linear drive member 6 is provided on the other side wall of the discharge bin 2. The linear drive member 6 adopts an electric push rod. A liquid inlet pipe 7 and a liquid outlet pipe 8 are respectively provided at the bottom and the middle of the side wall of the mixing tank 1.

[0032] like Figure 2 As shown, a partition is provided on the inner wall of the mixing tank 1, and a baffle ring 13 is provided in the partition. The baffle ring 13 divides the partition into a transmission chamber 21 and an insulation chamber 11 from top to bottom. The liquid inlet pipe 7 and the liquid outlet pipe 8 are respectively connected to the bottom and the top of the insulation chamber 11, and a spiral guide blade 12 is provided in the insulation chamber 11 to guide the liquid in the insulation chamber 11.

[0033] like Figure 1 and Figure 2As shown, the mixing assembly includes a driving motor 9 arranged on the top of the outer wall of the mixing tank 1, a main shaft 10 rotatably connected in the mixing tank 1 and driven by the driving motor 9 through a belt drive, and a stirring blade coaxially connected to the main shaft 10, the stirring blade is located below the screen 14, and a bracket supporting the bottom end of the stirring blade is provided at the bottom of the mixing tank 1.

[0034] like Figure 2 As shown, the output shaft of the linear drive member 6 extends into the discharge bin 2 and is provided with a piston which is slidably and sealedly connected to the inner wall of the discharge bin 2, thereby pushing the mixed material in the discharge bin 2 to the discharge pipe 5 for the next processing.

[0035] like Figure 2 , Figure 3 and Figure 5 As shown, the crushing assembly includes a collar 19 arranged on the side wall of the main shaft 10 and respectively located above and below the screen 14, three rotating shafts 20 respectively arranged at the ends of the collar 19, and rollers 15 respectively arranged on each rotating shaft 20, the rollers 15 roll along the upper surface and the lower surface of the screen 14 respectively, and the rollers 15 located above and below the screen 14 are in the same vertical plane.

[0036] like Figure 2 and Figure 4 As shown, the partition wall is rotatably sealed and connected with a rotating ring 23, and each rotating shaft 20 passes through the rotating ring 23 and extends into the partition, where an adjusting gear 24 is provided. A supporting ring 22 corresponding to the position of the screen 14 is provided in the partition, and a toothed disk is provided on the supporting ring 22.

When the card bead 1702 contacts and slides along the arc surface 26, the reset spring 1701 is gradually compressed. When the card bead 1702 reaches the cliff surface 27, the elastic potential energy of the reset spring 1701 is released, and then hits the screen 14, causing the screen 14 to produce a vibration effect, so as to avoid material accumulation on the screen 14.

[0038] When the main shaft 10 drives the stirring blades to rotate to mix the materials, it also drives the sleeve 19 and the rotating shaft 20 to rotate in the plane. During the rotation of the two rotating shafts 20 in the plane, the meshing between the adjusting gear 24 and the toothed disc causes the rotating shaft 20 to rotate vertically, thereby driving the roller 15 to rotate, so that when small particles agglomerate into the mixing tank 1, they stay on the screen 14 and are squeezed and broken by the roller 15, thereby avoiding the small particles agglomerating directly mixing with other raw materials and affecting the uniformity of the mixing of various raw materials. At the same time, it can avoid the problem of local overheating or incomplete sintering caused by different particle sizes in the subsequent sintering process.
