Description

Technical Field

[0001] The present application belongs to the technical field of material mixing, and in particular to a batch mixer. Background Art

[0002] At present, in order to reduce the differences in raw material batches and ensure product quality, most manufacturers mix different batches of materials evenly together to ensure the consistency of material batches. Batch mixers are generally used to mix materials. The mixing principle of batch mixers is generally to lift and stir materials in the batch mixer, and form a mixing flow field with gravity to achieve the mixing purpose. It has the advantages of high efficiency, strong adaptability, simple structure and low power consumption, so it is widely used in production.

[0003] However, in the entire material mixing and transportation process, after the materials in the batch mixer flow to other processes, some materials will be deposited in the batch mixer, especially the stirring blades and the connection between the stirring blades and the stirring shaft. If they are not cleaned, the next batch of materials will be contaminated. This increases the difficulty and uncertainty of quality stability control. The existing mixers generally have a manhole for cleaning at the upper feed inlet, but the mixing of each batch of materials requires manual cleaning, which affects production efficiency. In addition, the manual cleaning process is also prone to introduce external foreign matter and cause pollution. Utility Model Content

[0031] Currently, existing batch mixers have low production efficiency and are prone to contamination due to the need for manual cleaning of material deposits.

[0032] In view of the above problems, the present application provides a batch mixer, such as Figure 1 As shown, it includes: a conical barrel 1, a stirring mechanism 5 and a cleaning component 6. The position of the large end of the conical barrel 1 is higher than that of the small end. The large end is provided with an upper cover 2, and the upper cover 2 is provided with a feed port 21, and the small end is provided with a discharge port 3; the stirring mechanism 5 includes a stirring shaft 51 arranged in the conical barrel 1, a stirring blade 52 arranged on the stirring shaft 51, and a rotating drive member 4 arranged on the upper cover 2 and connected to the stirring shaft 51; the cleaning component 6 includes a support frame 61, a motion mechanism 62 and a nozzle 63. The support frame 61 is arranged at the upper end of the conical barrel 1 and connected to the upper cover 2, the motion mechanism 62 is arranged on the support frame 61, and the nozzle 63 is arranged on the motion mechanism 62. The nozzle 63 can be connected to an external air source, and the injection port of the nozzle 63 faces the stirring blade 52. The nozzle 63 can move in a direction perpendicular to the axial direction of the conical barrel 1 under the action of the motion mechanism 62 to reciprocate and purge the stirring blade 52.

[0033] A cleaning assembly 6 is arranged in the conical cylinder 1, a support frame 61 is arranged at the upper end of the conical cylinder 1 and connected to the upper cover 2, and a moving mechanism 62 is arranged on the support frame 61, so that the moving mechanism 62 can drive the nozzle 63 to move in a direction perpendicular to the axis of the conical cylinder 1, so as to reciprocately blow the stirring blade 52 and the connection between the stirring blade 52 and the stirring shaft 51. The batch mixer provided in the present application can automatically clean the stirring blade 52 and the connection between the stirring blade 52 and the stirring shaft 51, without the need for manual cleaning, thereby improving production efficiency and avoiding the contamination of materials by external pollution sources brought into the conical cylinder 1 due to manual cleaning.

[0034] The rotating drive member 4 may be a stirring motor, which is used to drive the stirring shaft 51 to rotate so as to drive the stirring blade 52 to rotate and mix the materials. The stirring blade 52 is a spiral stirring blade, which is connected to the stirring shaft 51 through a plurality of support rods 53.

[0035] In some embodiments of the present application, Figure 2 As shown, the motion mechanism 62 includes an active member 621 and a driven member 622 . The active member 621 is disposed on the support frame 61 . The driven member 622 can move under the drive of the active member 621 . The nozzle 63 is disposed on the driven member 622 .

[0036] The above-mentioned active member 621 is used to drive the driven member 622 to move in a direction perpendicular to the axial direction of the conical cylinder 1, so that the nozzle 63 on the driven member 622 can perform a range-wide sweep on the stirring blade 52. Exemplarily, the above-mentioned active member 621 can be an electric push rod, a cylinder or a rotary cylinder, etc., which can drive the driven member 622 to move in a direction perpendicular to the axial direction of the conical cylinder 1.

[0037] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the active member 621 is an incomplete gear, including a gear body 6211 and teeth arranged on a part of the outer circumferential surface of the gear body 6211. The gear body 6211 is sleeved on the stirring shaft 51. A limit block 511 is arranged on the stirring shaft 51. A limit groove 62111 is arranged on the gear body 6211 corresponding to the limit block 511. The driven member 622 includes two oppositely arranged racks 6221. One end of the two racks 6221 in the same direction is connected by a connecting rod 6221. The incomplete gear meshes with one of the two racks 6221 when rotating.

[0038] The above-mentioned active member 621 adopts an incomplete gear and the gear body 6211 is sleeved on the stirring shaft 51, which can save energy and directly use the energy brought by the rotation of the stirring shaft 51 to drive the active member 621 to rotate, thereby driving the driven member 622 to reciprocate in a direction perpendicular to the axial direction of the conical cylinder 1, so that the nozzle 63 on the driven member 622 can comprehensively purge the stirring blade 52.

[0039] In some embodiments of the present application, Figure 2 As shown, two slide rails 611 are relatively arranged on the support frame 61 , and two racks 6221 are respectively located in the two slide rails 611 . The two slide rails 611 can limit the axial position of the driven member 622 to the stirring shaft 51 .

[0040] The slide rail 611 is used to limit the follower 622 so as to make the movement of the follower 622 more stable and smooth.

[0041] In some embodiments of the present application, Figure 1 As shown, the batch mixer also includes a linear drive 7, a fixed end of the linear drive 7 is connected to the upper cover 2, and an output end of the linear drive 7 is connected to the support frame 61 and can drive the cleaning component 6 to move axially along the stirring shaft 51 so that the limit block 511 is engaged or separated with the limit groove 62111.

[0042] The above-mentioned linear drive 7 can drive the support frame 61 to move axially along the stirring shaft 51, so as to drive the active member 621 and the driven member 622 to move axially in the stirring shaft 51, so that the limit block 511 can be engaged or separated with the limit groove 62111 to achieve the working state of the control motion mechanism 62.

[0043] In some embodiments of the present application, Figure 1 As shown, the position of the limiting block 511 is higher than the position of the limiting groove 62111.

[0044] The position of the limiting block 511 is higher than that of the limiting groove 62111 so that the linear actuator 7 can be more tightly engaged with the limiting groove 62111 when driving the active member 621 to move up and down.

[0045] In some embodiments of the present application, the linear drive 7 is a cylinder, the cylinder body of the cylinder is connected to the upper cover 2 , and the piston rod of the cylinder is connected to the support frame 61 .

[0046] In some embodiments of the present application, Figure 1 As shown, there are two cylinders, the cylinder bodies of the two cylinders are respectively connected to the upper cover 2, and the piston rods of the two cylinders are respectively connected to the support frame 61.

[0047] Two cylinders are used to drive the support frame 61 to move, and the cylinder bodies of the two cylinders are respectively connected to the two connecting rods 6221, so that the force exerted by the cylinders on the support frame 61 can be more uniform.

[0048] In some embodiments of the present application, Figure 1 As shown, the batch mixer further comprises a frame 8, and the conical barrel 1 is arranged on the frame 8 to ensure stability.

[0049] When the batch mixer provided by an embodiment of the present application is used, Figure 1 and Figure 2 As shown, the rotating driving member 4 drives the stirring shaft 51 to drive the incomplete gear to rotate, and the incomplete gear drives the nozzle 63 connected to the driven member 622, so that the nozzle 63 reciprocates to purge, and the rotation of the stirring shaft 51 drives the rotation of the stirring blade 52 to achieve full coverage automatic purge. When purge is not needed during the production process, the linear drive 7 is used to disengage the limit block 511 from the limit groove 62111, which can reduce wear.

[0050] The batch mixer provided in one embodiment of the present application is used for batch mixing. Figure 1 and Figure 2 As shown, the linear drive 7 moves the cleaning component 6 toward the small end, the limit block 511 is disengaged from the limit groove 62111, and the cleaning component 6 is in a standby state, thereby avoiding wear caused by ineffective operation and increasing the service life; after the batch mixed materials pass through the discharge port 3, automatic cleaning is turned on: the linear drive 7 moves the cleaning component 6 toward the large end, the limit block 511 is engaged with the limit groove 62111, and the stirring shaft 51 begins to drive the incomplete gear to rotate, thereby driving the follower 622 to reciprocate; the incomplete gear only engages with one rack 6221 when rotating, and when engaging with the rack 6221, it will disengage from the other rack 6221, thereby driving the follower 622 to reciprocate in a direction perpendicular to the axial direction of the conical cylinder, and the nozzle 63 on the follower 622 blows back and forth, and cooperates with the rotation of the stirring blade 52 to achieve the effect of fully blowing the stirring blade 52 and the place where materials are prone to accumulate above the support rod 53.

[0051] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
