Description

Technical Field

[0001] The utility model relates to the technical field of ceramic production lines, in particular to a mixing device. Background Art

[0002] Currently, mixers are primarily used to stir and mix multiple raw materials to obtain a uniform mixture, which is beneficial for improving the production quality of ceramics. To this end, the applicant or a company affiliated with the applicant has designed a mixer for use in ceramic production lines (a patent has been applied for and granted for the mixer, with Chinese patent application number 201720629517.6). The mixer primarily comprises a frame, a mixing barrel mounted on the frame, a drive device for rotating the mixing barrel, and a discharge hood mounted on the frame. The discharge hood is provided with an inlet, which is placed over the output end of the mixing barrel through the inlet. During use, the discharge hood prevents dust sprayed from the output end of the mixing barrel from flying out, thereby reducing the dust concentration in the workshop environment and minimizing the health impact on workshop employees. However, in actual application, this technical solution still has the following deficiencies: During production, in order not to affect the rotation of the mixing barrel, a movable gap is usually reserved between the feed inlet and the output end of the mixing barrel. Moreover, since the mixer is not provided with a dust shield to cover the movable gap, the movable gap becomes an open circulation channel, so that the dust in the material cover can easily overflow to the outside through the movable gap, resulting in a large amount of dust flying in the workshop environment, which still has a significant adverse effect on the health of workshop employees. Therefore, it is very necessary to design a mixing device that can further reduce dust overflow and flying, so as to better meet people's application needs and protect the health of workshop employees. Utility Model Content

[0003] The purpose of the present utility model is to solve the above-mentioned problems and deficiencies, and to provide a mixing device. The mixing device, by providing a conical dust-blocking flange, can directly block the active gap, thereby blocking most of the dust that drifts toward the active gap, thereby achieving the first purpose of preventing dust from overflowing. Moreover, by providing a closing channel structure from large to small, the dust that flies into the closing channel structure can be congested and difficult to pass through the active gap, so that most of the dust can only settle to the bottom of the discharge cover and be discharged, thereby achieving the second purpose of preventing dust from overflowing. Through such a double dust-blocking effect, the amount of dust overflow can be greatly reduced, thereby further reducing the dust concentration in the workshop environment, and thus further reducing the impact on the health of workshop employees.

[0021] like Figure 1 and Figure 3 As shown, the mixing device described in the present invention includes a frame 1 with a mixing barrel 2 and a discharge cover 3, and a driving mechanism 4 for driving the mixing barrel 2 to rotate. In order to achieve the purpose proposed by the present invention, as shown in FIG. Figure 3As shown, the utility model also includes a conical output barrel 21, the large end of the conical output barrel 21 is connected to the output end of the mixing barrel 2, and the small end of the conical output barrel 21 is provided with a conical dust-blocking flange 22 folded outward, and a V-shaped dust-blocking ring groove 23 is formed between the conical dust-blocking flange 22 and the conical output barrel 21; the discharge cover 3 is provided with a feeding ring 30, the discharge cover 3 is placed on the conical dust-blocking flange 22, and the feeding ring 30 is placed in the V-shaped dust-blocking ring groove 23, and a movable gap 24 is formed between the feeding ring 30 and the bottom of the V-shaped dust-blocking ring groove 23, and a closing channel structure 25 from large to small is formed between the movable gap 24 and the conical dust-blocking flange 22. The utility model provides a conical dust shield flange 22 to directly shield the movable gap 24, thereby blocking most of the dust that drifts toward the movable gap 24, thereby achieving the first purpose of preventing dust from overflowing. Moreover, by providing a closing channel structure 25 from large to small, dust that flies into the closing channel structure 25 is blocked and difficult to pass through the movable gap 24, so that most of the dust can only settle to the bottom of the discharge cover 3 and be discharged, thereby achieving the second purpose of preventing dust from overflowing. This dual dust shielding effect can greatly reduce the amount of dust overflow, further reduce the dust concentration in the workshop environment, and thus further reduce the impact on the health of workshop employees.

[0022] During actual assembly, by setting the V-shaped dust shield ring groove 23, on the one hand, it can facilitate rapid positioning with the inlet ring 30 of the discharge cover 3 to improve the convenience of assembly, and on the other hand, it can facilitate the manufacture of the closing channel structure 25.

[0023] In actual application, Figure 3 As shown, the spacing L of the movable gap 24 is 0.1-0.3 mm. Preferably, the spacing L of the movable gap 24 is 0.2 mm. This ensures that the mixing drum 2 has sufficient space for rotation, while also keeping the spacing of the movable gap 24 small enough to prevent dust from escaping, further reducing the dust concentration in the workshop environment and thus reducing the impact on the health of workshop employees.

[0024] In order to further improve the structure of the discharge cover 3, as Figure 2 and Figure 6 As shown, the discharge cover 3 comprises a semicircular cover body 31 and a discharge funnel 32. One end of the semicircular cover body 31 is hingedly connected to the discharge funnel 32, and the semicircular cover body 31 covers the upper end of the discharge funnel 32. The semicircular cover body 31 and the discharge funnel 32 are each provided with a semicircular bayonet 33 for connecting them together. The feed ring 30 is formed by enclosing the two semicircular bayonet 33. This facilitates opening the discharge cover 3 for cleaning and maintenance of the conical dust-proof flange 22, the conical output barrel 21, and the mixing barrel 2, and also facilitates observation of the mixing status.

[0025] In order to make the semicircular cover 31 and the discharge funnel 32 not easy to loosen, Figure 1 As shown, the discharge cover 3 also includes an openable and closable locking member 34, through which the other end of the semicircular cover 31 is connected to the discharge hopper 32 in an openable and closable manner. This allows the other end of the semicircular cover 31 to be locked to the discharge hopper 32, preventing it from becoming loose. When the semicircular cover 31 needs to be opened, the locking member 34 can be opened, making it very convenient and reliable to use. In actual use, the locking member 34 adopts a commonly used lock buckle on the market, for example, the lock buckle structure disclosed in the Chinese patent application number CN200620140834.3, entitled "Lock Buckle". The specific structure and working principle of the lock buckle are not further elaborated here.

[0026] In actual application, the bottom of the discharge funnel 32 is the discharge port. A collection bag can be directly placed at the bottom of the discharge funnel 32 to collect the mixed material, or the input end of the conveyor belt can be placed below the discharge funnel 32 to directly convey the mixed material to the next process for processing and manufacturing. When a conveyor belt is used for feeding, in order to further prevent dust, such as Figure 4 As shown, dust shields 35 are provided on the left, right and rear sides of the lower end of the discharge funnel 32, and the bottom surface of the dust shield 35 is lower than the bottom surface of the discharge funnel 32. This not only prevents dust, but also reserves one side for the conveyor belt to feed, making it more reliable to use.

[0027] In order to further improve the stirring effect of the stirring barrel 2 and make the mixing of the raw materials more uniform, Figure 3 and Figure 5 As shown, multiple groups of strip stirring arrays 20 are also installed on the inner wall of the mixing barrel 2 in a circular pattern. Each group of strip stirring arrays 20 is composed of multiple stirring paddles 201 arranged in an inclined shape, and a feeding gap 202 is formed between two adjacent stirring paddles 201. By providing multiple groups of strip stirring arrays 20 and multiple stirring paddles 201, more stirring components can be formed to increase the number of stirring times of the raw materials, thereby making the mixing of the raw materials more uniform. By providing a feeding gap 202 between two adjacent stirring paddles 201, not only can the raw materials flow through, but more feeding gaps 202 can be formed, thereby extending the stirring time of the raw materials in the mixing barrel 2, thereby making the mixing of the raw materials more uniform.

[0028] In order to make it easier for the conical output barrel 21 to output the mixed material, Figure 3 and Figure 5As shown, the inner wall of the conical output barrel 21 is also annularly mounted with a plurality of guide paddles 211. Each guide paddle 211 is arranged obliquely on the inner wall of the conical output barrel 21, and the ends of each guide paddle 211 in the longitudinal direction extend to the input and output ends of the conical output barrel 21, respectively. This allows for easy and reliable discharge of the mixed material, preventing it from accumulating in the conical output barrel 21.

[0029] In order to keep the raw materials in the mixing barrel 2 without affecting the mixing, and to make the raw materials automatically flow to the output end of the mixing barrel 2, such as Figure 1 As shown, the mixing barrel 2 is arranged on the frame 1 in an inclined manner with the input end facing upward and the output end facing downward.

[0030] In order to further improve the structure of the driving mechanism 4, make it simple, scientific and reasonable, and easy to manufacture, as Figure 3 As shown, the drive mechanism 4 includes a rotating shaft 41, a connecting rod 42, and a transmission motor 43 disposed at one end of the frame 1. A bearing seat 11 is also disposed at the other end of the frame 1. The rotating shaft 41 is inserted into the mixing drum 2 and arranged on the same central axis as the mixing drum 2. The rotating shaft 41 and the mixing drum 2 are connected together by the connecting rod 42. The two ends of the rotating shaft 41 are respectively connected to the bearing seat 11 and the power output end of the transmission motor 43. This makes it very easy to drive the mixing drum 2 to rotate without affecting the input and output of raw materials in the mixing drum 2.

[0031] In order to further improve the structure of the mixing device, the raw materials can be accurately transported to the mixing barrel 2, such as Figure 1 and Figure 3 In the embodiment, the input end of the mixing barrel 2 is an open structure, and the frame 1 is also provided with a feeding funnel 5 for introducing raw materials into the input end of the mixing barrel 2; the input end of the feeding funnel 5 is provided with a funnel-shaped feeding port 51, and the output end of the feeding funnel 5 is placed in the mixing barrel 2 from the input end of the mixing barrel 2. This allows the raw materials to be accurately delivered to the mixing barrel 2 without spilling out, and is very reliable to use.
