Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a double-shaft paddle mixer. Background Art

[0002] A mixer is a mechanical device that uses mechanical force and gravity to evenly mix two or more materials. During the mixing process, it can also increase the contact surface area of ​​the materials to promote chemical reactions and accelerate physical changes. Commonly used mixers are divided into four categories: gas and low-viscosity liquid mixers, medium- and high-viscosity liquid and paste mixers, and powdered and granular solid material mixers. In order to obtain the degree of mixing uniformity, sampling and observation are required. The existing sampling structure is very simple, which is a sampling tube that passes into the cylinder. The outer port of the sampling tube is sealed with a wire plug or a stopper. When sampling, open the wire plug or the stopper, and the material slides into the sampling cup by gravity.

[0003] However, the sampled material can only slide down by gravity, which may easily lead to blockage of the port of the sampling tube. At the same time, when the sampling tube is opened, the pressure inside the mixer is different from that outside, which may cause material spraying, resulting in adverse consequences. In view of this, a double-shaft paddle mixer is proposed to solve the above problems. Utility Model Content

[0006] The sampling mechanism includes a cavity, a fixing rod and a control panel. The upper end of the shell is provided with a cavity, two partitions are fixed in the cavity, a first sealing plate that can move left and right is arranged horizontally in the partition, a pressure sensor is fixed at the lower end of the first sealing plate, an infrared sensor is fixed on the partition, and a material storage frame that can move up and down is placed in the cavity;

The upper end of the cavity is provided with a sampling slot for taking out the material storage frame.

[0008] Furthermore, a control panel is fixed on the housing, and the infrared sensor is located between the first sealing plate and the second sealing plate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. When sampling the mixed material, the double-shaft paddle mixer drives the second sealing plate to move to two sides apart by starting the second electric push rod. At this time, the material storage frame descends to between the first sealing plate and the second sealing plate, and then drives the second sealing plate to move to the opposite side by the second electric push rod for sealing. Then, the first sealing plate is driven to move to two sides apart by starting the first electric push rod, so that the material storage frame can descend to the inside of the shell for sampling. After sampling, the material storage frame moves to above the first sealing plate, and then the two sealing plates move relative to each other to seal the bottom of the cavity. Then, the material storage frame is sensed by the setting of the infrared sensor, and the second sealing plate moves to two sides apart, so that the material storage frame can be taken out.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 A double-shaft paddle mixer in this embodiment includes a housing 1, a sampling mechanism 2 is provided on the housing 1, and an observation window 3 is embedded in the housing 1.

[0021] The sampling mechanism 2 includes a cavity 202, a fixing rod 207 and a control panel 201. The upper end of the housing 1 is provided with a cavity 202, and two partitions 208 are fixed to the cavity 202. A first sealing plate 209 that can move left and right is transversely arranged in the partition 208. A pressure sensor 211 is fixed to the lower end of the first sealing plate 209. When the material storage frame 212 abuts against the pressure sensor 211, an infrared sensor 213 is fixed on the partition 208. When the infrared sensor 213 senses the material storage frame 212, the second sealing plate 210 can be controlled to move to both sides, so that the material storage frame 212 is taken out. The material storage frame 212 that can move up and down is placed in the cavity 202;

[0022] The first electric push rod 203 and the second electric push rod 204 are fixed to the left and right sides of the inner cavity of the cavity 202, respectively. The first sealing plate 209 is fixed to the output end of the first electric push rod 203, and the second sealing plate 210 is fixed to one end of the second electric push rod 204. Semicircular holes for movement of the fixed rod 207 are provided on the opposite sides of the two first sealing plates 209 and the second sealing plates 210, so as to facilitate the movement of the fixed rod 207. When the fixed rod 207 moves up and down, the two first sealing plates 209 and the second sealing plates 210 move relative to each other, so that the two semicircular holes can be moved by the fixed rod 207. A sampling slot for taking out the material storage frame 212 is provided at the upper end of the cavity 202.

[0023] A plurality of fixing rods 207 are fixed to the upper end of the material storage frame 212, a pull plate 205 is fixed to the fixing rods 207, a guide rod 206 is fixed to the outer shell 1, and a through hole is provided on the pull plate 205 for sliding connection with the guide rod 206, so that the fixing rod 207 can move up and down stably.

[0024] The device places a material storage frame 212 in the cavity 202, and then drives the second sealing plate 210 to move to two sides away from each other through the second electric push rod 204. Then the second electric push rod 204 drives the second sealing plate 210 to move to the opposite side, so that the second sealing plate 210 fits with the fixed rod 207, and then starts the first electric push rod 203 to drive the first sealing plate 209 to move to both sides, so that the material storage frame 212 can be lowered to the inside of the shell 1 for sampling.

[0025] Among them, a control panel 201 is fixed on the shell 1 to facilitate controlling the opening and closing of the first electric push rods 203, 204 and the second electric push rod 204. The infrared sensor 213 is located between the first sealing plate 209 and the second sealing plate 210 to facilitate sensing the material storage frame 212.

[0026] At the same time, an opening is provided at the lower end of the cavity 202 for the material storage frame 212 to enter the interior of the housing 1, so that the material storage frame 212 can enter the interior of the housing 1 for sampling.

[0027] In addition, the two first sealing plates 209 and the second sealing plates 210 are distributed up and down, and the upper and lower opposite sides of the two first sealing plates 209 and the second sealing plates 210 are slidably connected, so that when the two first sealing plates 209 and the second sealing plates 210 move relative to each other, the semicircular hole can be sealed.

[0028] The working principle of the above embodiment is:

[0029] First, align the through hole on the pull plate 205 with the guide rod 206, and then the pull plate 205 drives the fixed rod 207 to move downward, and then the second sealing plate 210 is driven to move to the two sides apart by starting the second electric push rod 204, and the fixed rod 207 can be lowered again. At this time, the material storage frame 212 is lowered to between the first sealing plate 209 and the second sealing plate 210, and then the second sealing plate 210 is driven to move to the opposite side by the second electric push rod 204, so that the second sealing plate 210 is slightly close to the fixed rod 207 for sealing.

[0030] Then, the first electric push rod 203 is started to drive the first sealing plate 209 to move to the two sides apart. At this time, the material storage frame 212 can be lowered to the inside of the shell 1 for sampling. At this time, the first electric push rod 203 drives the first sealing plate 209 to move to the opposite side to reduce the gap. After sampling, the fixed rod 207 moves upward, so that the upper end of the material storage frame 212 abuts against the pressure sensor 211, so that the first electric push rod 203 drives the first sealing plate 209 to move to the two sides apart and move to between the first sealing plate 209 and the second sealing plate 210.

[0031] The first electric push rod 203 then drives the first sealing plate 209 to move to the two sides apart to seal the bottom of the cavity 202, and then the infrared sensor 213 senses the material storage frame 212, and the second electric push rod 204 drives the second sealing plate 210 to move to the two sides apart, and then the material storage frame 212 is pulled up to be taken out.
