Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a single-machine bag dust collector. Background Art

[0002] The single-machine bag filter is a type of filter-type dust collector. It is a device that allows the dust-laden airflow to pass through the filter material to separate and capture the dust. This device mainly uses fiber fabric as filter material and is often used in the dust removal of industrial exhaust gas. Its dust removal efficiency can generally reach more than 99%. Although it is one of the oldest dust removal methods, it is increasingly widely used due to its high efficiency, stable and reliable performance, and simple operation.

[0003] The filter cloth inside the existing single-machine bag dust collector plays the main function of filtering. Once it is damaged, it will affect the filtering effect of the air, and the existing filter cloth is relatively cumbersome to replace. Therefore, a single-machine bag dust collector is proposed.

[0004] A patent with a publication number of CN207805252U is disclosed in the prior art. The solution includes a box body, a plurality of filter bags and an induced draft fan arranged inside the box body. The box body is also provided with an air inlet and an air outlet. When the induced draft fan is started, the air flow is sucked in from the air inlet, and the air flow is discharged from the air outlet after being filtered by the filter bag. The box body is also provided with an ash storage drawer, which is located below the filter element and is used to collect fallen dust. The ash storage drawer can be drawn out of the box body. A vibrating and cleaning mechanism is also provided in the box body, which is used to vibrate the filter bag to make the dust fall. The utility model has the advantages of dust not being easy to deposit.

[0005] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:

[0006] First, as the existing bag dust collector is used, a large amount of impurities are easily accumulated on the inner wall, so that when the existing device cleans the bag, the dust is still inside the bag. As the gas enters the bag during use, it is easy to adhere to the bag again, affecting the air circulation.

[0007] Second, when the existing bag dust collector is used, the bag is prone to folding, which affects the contact area with the air and thus reduces the filtering efficiency of the bag.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] In view of the defects in the prior art, the utility model solves the problem that a large amount of impurities are easily accumulated on the inner wall of the bag-type dust collector in the traditional technology during use, so that when the existing device cleans the bag, the dust is still inside the bag. As the bag is used, the gas enters and easily adheres to the bag again, affecting the air circulation; and the existing bag-type dust collector is prone to folding when used, which affects the contact area with the air and reduces the filtering efficiency of the bag.

[0010] In order to solve the above problems, the utility model provides the following technical solutions:

[0011] The single-machine bag dust collector comprises a box shell, an air inlet cylinder is fixedly connected horizontally in the box shell, a mounting cylinder is inserted in the air inlet cylinder, a blocking plate is fixedly connected to the outer end of the mounting cylinder, and a slag discharge hole and an air outlet hole are opened on the upper and lower side walls of the mounting cylinder from top to bottom, and a dust bag is arranged in the air outlet hole.

[0012] The installation cylinder is slidably arranged along its axial direction through a transverse member, and is also rotatably arranged along its circumferential direction through a steering member. A shielding plate is fixedly connected to the upper end of the air inlet cylinder, and when the slag discharge hole is located at the upper part, the shielding plate closes the slag discharge hole.

[0013] As an optimized solution, the air outlet is internally threadedly connected with a connecting ring, the lower end of the connecting ring is fixedly connected with a supporting net cylinder, and the cloth bag is mounted on the supporting net cylinder.

[0014] As an optimized solution, a dust removal striking hammer is rotatably provided on the inner top of the box shell.

[0015] As an optimized solution, a rotating shaft is provided at the inner top of the box shell for vertical rotation, and a plurality of ball joint seats are fixedly connected from top to bottom on the opposite side walls of the rotating shaft, and a connecting rod is fixedly connected to the movable end of each ball joint seat, and a plurality of dust removal striking hammer bodies are provided corresponding to the connecting rod and are fixedly connected to the swinging end of the connecting rod.

[0016] As an optimized solution, the transverse moving member includes a telescopic cylinder horizontally fixed to the outer wall of the box shell, the telescopic rod of the telescopic cylinder extends into the box shell, and a transverse axis is coaxially fixed to the outer wall of the blocking plate, and the other end of the transverse axis is fixed to the telescopic rod of the telescopic cylinder through a turntable.

[0017] As an optimized solution, the steering member includes a driving machine, the output end of the driving machine is fixedly connected to a spur gear, the peripheral wall on the horizontal axis is surrounded by teeth, and the spur gear meshes with the teeth and is in sliding contact with the teeth.

[0018] As an optimized solution, a bracket is fixedly connected to the inner wall of the box shell, and the driving motor is fixedly connected to the bracket.

[0019] As an optimized solution, the outer top surface of the box shell is fixedly connected to the drive motor, and the output shaft of the drive motor is fixedly connected to the upper end of the rotating shaft.

[0020] As an optimized solution, a discharge tube which is arranged to taper downward is fixedly connected to the lower end of the box shell, and a discharge valve is fixedly connected to the lower end of the discharge tube.

[0021] As an optimized solution, an air outlet connected to the inner cavity of the box shell is fixedly connected to the outer wall of the box shell.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] By setting a supporting mesh tube, the cloth bag can be supported to increase its contact area with the air, thus overcoming the problem of reduced contact area with the air due to flat folding;

[0024] During normal dust removal use, air enters through the air inlet cylinder, passes through the bag filter and enters the box shell, and is discharged through the air outlet cylinder. When the bag is removing dust, the air inlet is closed, and the telescopic cylinder pulls the mounting cylinder out of the air inlet cylinder to expose the slag discharge hole. At this time, the driving motor rotates and drives the mounting cylinder to rotate 180°, so that the bag is located at the engine, and the slag discharge hole is located below. The driving motor drives the shaft to rotate. The ball joint seat can be used to control the rotation range of the dust removal hammer through the shaft speed, and the dust removal hammer is used to hit the surface of the bag. Under the action of the supporting mesh cylinder, the dust removal hammer hits the supporting mesh cylinder to make it vibrate, so as to knock down the dust on the inner surface of the bag. The knocked-down dust enters the inside of the box shell through the slag discharge hole, gathers in the outlet cylinder, and is discharged by opening the discharge valve; the dust removal and cleaning efficiency of the bag is improved, the air flow is ensured, and the efficiency of the bag dust collector is improved.
